When skimming,readers only try to locate specific information and they often do not even follow the development of the story.(10)Scanning is another technique readers often use when looking up a word in a telephone book or dictionary to search for key words or ideas.Scanning involves moving your eyes quickly down the page to seek specific words and phrases.Based on this,I will introduce to you three strategies which may help you to conduct effective reading.First,make sure the books are specific to your age and reading levels.Second,find some background information which relates to the book before reading.Third,leave plenty of time for reflection and let yourself be free to develop imagination at the end of the reading.OK,today we had a brief look at the ways to be effective readers,and the skills of reading as well. Undoubtedly,reading is always beneficial.I hope you'll enjoy reading and keep reading after today's lecture.Thank you for your attention.【精解精析】1.written information【定位】First of all,I'd say,reading is a method of absorbing written information.(第二段第一句)【解析】根据定位句可知,作者认为读书首先是对书面信息的吸收,此处缺少名词,故填入written information。

What is the woman writing about?14. W here did the woman’s articles usually appear?15. What does the woman expect?Section BPassage OneBody language, especially gestures, varies among cultures. For example, a nod of the head means “yes” to most of us. But in B ulgaria and Greece a nod means “no” and a shake of the head means “yes”. Likewise, a sign for OK, forming a circle with our forefinger and thumb, means zero in France and money in Japan. Waving or pointing to an Arab business person would be considered rude, because that is how Arabs call their dogs over. Folded arms signal pride in Finland, but disrespect in Fiji. The number of bows that the Japanese exchange on greeting each other, as well as the length and the depth of the bows, signals the social status each party feels towards each other. Italians might think you’r e bored unless you use a lot of gestures during discussions. Many American men sit with their legs crossed with one ankle resting over the opposite knee. However, this would be considered an insult in Muslim countries, where one will never show the sole of the foot to a guest. Likewise, Americans consider eye contact very important, often not trusting someone who is afraid to look at you in the eye. But in Japan and many Latin American countries, keeping the eyes lowered is a sign of respect. To look at your partner fully in the eyes is considered a sign of ill breeding and is felt to be annoying.Questions 16 to 18 are based on the passage you’ve just heard.16. What gesture do Bulgarians and Greeks use to express negative responses?17. What is likely to offend Arab business people?18. What is considered to be impolite in Muslim countries?Passage TwoThree years ago, Puncha Maya, her husband and five children lived in a shaky flat in southern Nepal. Every morning, the parents walked the dirt roads, seeking work in the rice fields. After the harvest, the family went begging for food. Today, the Mayas own a small paperbag-making company. With the money they’ve earned, the Mayas have purchased a small plot, on which they grow vegetables and raise goats for additional income. In fact, the family has saved $ 68. this is remarkable in a country with an average annual income of $160. grace Monbka, her husband and eight children, once lived hand-t-mouth in Cameroon. Today, the Monbkas run a clothing-manufacturing business and own a home. They’ve able to send their children to school at a costly annual sum of $ 2,800. the idea of starting her own business seemed impossible to Pillar Moya, a poor woman from Atahualpa, high in Ecuador’s Andes Mountains. Today, however, she’s one of the proud owners of a bakery specialized in sweet cakes.These businesses are part of an economic revolution sweeping the developing world. The sponsor is the Trickle Up Program, a non-profit organization founded by New Yorkers Glen and Mildred Leet. This organization offers people like the Mayas, the Monbkas and the Moyas modest $grants. Since 1979, the program has helped over 130,000 of the world’s neediest people in 90 countries win small life-saving victories over poverty. And it has turned conventional thinking about foreign aid on its head.Questions 19 to 21 are based on the passage you’ve just heard.19. what do you learn about Puncha Maya’s family of three years ago?20. what are the Monbkas able to do now?21. what does the speaker mainly talk about?Passage ThreeTake care of your teeth and your teeth will take care of you. Your teeth are a living part of your body. They have nerves and blood vessels. Diseased teeth can cause pain, die and fallout.Plaque is the main enemy of healthy teeth. Everyone has plaque. It is a sticky, colorless film that coats the teeth. Plaque is always forming on the teeth especially at the gum line. If plaque is not removed, it builds up and gets under the gum line. Plaque that is left on the teeth for some time hardens. The result is tooth decay and gum disease. The bacteria in plaque live on sugar. They change sugar into acids which break down the tooth’s harder outer-covering. If left untreated, decay goes deeper and deeper into the tooth. After a while the decay reaches the nerves and blood vessels of the inner tooth. By the time this happens, the tooth has probably started to ache.In addition to tooth decay there are also gum diseases to watch out for. The bacteria in plaque make poisons that attack the gums. Small pockets form around the teeth. The pockets trap more bacteria and food particles. Finally, the bone supporting the teeth is attacked and starts to shrink. Teeth become loose and may fall out. Adults lose most teeth this way. Keep your mouth healthy. When you brush your teeth, do a good job.Questions 22 to 25 are based on the passage you’ve just heard.22. what does the speaker say about your teeth?23. what does the speaker say about plaque?24. why is sugar harmful to teeth?25. what causes adults to lose most of their teeth according to the speaker?Section CStunt people (替身演员) are not movie stars, but they are the hidden heroes of many movies.They were around long before films. Even Shakespeare may have used them in fight scenes.must be set up so that no one gets hurt. It is almost like planning a dance performance.named Jan Davis does all kinds of jumps. She has leapt from planes and even off the top of a waterfall. Each jump required careful planning and expert (33)timing.Yakima Canutt was a famous cowboy stunt man. Among other stunts, he could jump from a second story window onto a horse’s back. He (34)invented the famous trick of sliding under aonly stunt man ever to get an Oscar.。

If the body has only partially decayed, it is reburied in a smaller cheaper grave, but not for long, the body will be dug up again some time later when it has fully decayed. Buying a piece of land for a grave is the only way to avoid this process. The cost of the grave is so great that most p0eople choose to rent the grave for three years and even after it has been dug up, lasting peace is still not guaranteed. If no one pays for renting space in the bone room, the skeleton is removed and stored in a building in a poor part of the town. Lack of space in Athens is the main reason why the dead are dug up after the three years. The city is so overcrowded that sometimes dead bodies are kept in the hospitals for over a week until a grave is found. Athens’ city council wants to introduce cremation, that is burning dead bodies as a means of dealing with the problems. But the Greek church resists this practice, they believe the only place where people burn is hell, so burning dead bodies is against the Greek concept of life after death. To save space, the church suggested burying the bodies standing up instead of lying down. Some people proposed building multi-storey underground grave yards.26. What must Greeks do to keep the dead resting in ever-lasting peace?27. Why are most dead bodies in Athens dug up after three years?28. What suggestions does the church give about the burying of dead bodies?29. What practice does the Greek church object to?Passage TwoIf you visit a big city anywhere in the world, you will probably find a restaurant would serve the food of your own native country. Most large cities in the United States offer international sample of foods. Many people enjoy eating the food of other nations. This is probably one reason why there are so many different kinds of restaurants in the United States. A second reason is that many Americans come from other part of the world. They enjoy tasting the foods of their native lands. In the city of Detroit, for example, there are many people from western Europe, Greece,Latin America, and the Far East. There are many restaurants in Detroit which serve the foods of these areas. There are many other international restaurants too. Americans enjoy the foods in these restaurants as well as the opportunity to better understand the people and their way of life. One of the most common international restaurants to be found in the United States is the Italian restaurant. The restaurant may be a small business run by a single family. The mother of the family cooks all of the dishes, and the father and children serve the people who come to eat there. Or it may be a large restaurant owned by several different people who worked together in the business. Many Italian dishes that Americans enjoy are made with meats, tomatoes and cheese, they are very delicious and tasty.30. Why are there so many international restaurants in the United States?31. Why do Americans like to go to international restaurants apart from enjoying the foods there?32. How is a typical Italian family restaurant run in the United States?Passage ThreeOne winter day in 1891, a class at a training school in Massachusetts, U.S.A, went into the gym for their daily exercises. Since the football season had ended, most of the young man felt they were in for a boring time.But their teacher, James Nasmith had other ideas. He had been working for a long time on a new game that would have the excitement of the American football. Nasmith showed the men a basket he had hung at the each end of the gym, and explained that they were going to sue a round European football, at first everybody tried to throw the ball into the basket no matter where he was standing. “Pass! Pass!” Nasmith kept shouting, blowing his whistle to stop the excited players. Slowly, they began to understand what was wanted of them. The problem with the new game, which was soon called “basketball”, was getting the ball out of the basket. They used ordinary food baskets with bottoms and the ball, of course, stayed inside. At first, someone had to climb up every time a basket was scored. It was several years before someone came up with the idea of removing the bottom of the basket and letting the ball fall through. There have been many changes in the rules since then, and basketball has become one of the world’s most popular sports.33. What did Nasmith do to entertain his students one winter day?34. According the speaker, what was the problem with the new game?35. How was the problem with the new game solved?。

News Report OneNew tougher alcohol guidelines have been published which reduce the recommended drinking limits and[1] call for some days every week,away from alcoholic beverages.It says if people drink,it should be moderately over three or more days and that some days should be alcohol-free.Pregnant women should not drink at all.The guidance from the UK’s chief medical officers,which says there is no safe level,set s a new limit of 14 units-equivalent to six pints of beer or seven glasses of wine-a week.The 14-unit limit has been chosen because at that point,[2]your drinking leads to 1% risk of dying from alcohol-related causes.This has been considered an acceptalbe level of risk as it is approximately the same risk that someone has when they do an everyday task such as driving a car.1.What is the key information of the latest-issued guidelines?2.Why are 14 units regulated in the latest-issued guidelines?News Report TwoOver the past decade,New York’s most populous marketplace has emerged f rom the shadow of Manhattan to become the most fashionable part of the largest city in the US.Helped by its cheaper rents compared with Manhattan,artists and hip young people have breathed new life into Brooklyn.[3]This has established a creative culture and atmosphere that started in neighbourhoods before spreading out across the market.Mr.Demby and Mr.Butler’s idea was to create a street market to bring together Brooklyn’s newfound artistic culture and renewed community spirit.So eight years ago they rented out a large school yard and launched Brooklyn Flea,a street fair for salesmen selling antiques,crafts and food.Today it is the most popular street market in New York,[4] from April to November typically hosts 140 sellers every Saturday and Sunday across two outdoor locations.And from December to March it is held equally popular indoors.3.What is the contribution of the street market?4.How often is the street market held?News Report ThreeHSBC says all its online banking services are operating at full capacity again,after two days of disorder.Throughout Monday and most of Tuesday,[5]the personal banking site was not allowing customers to log on,while business accounts were running slowly.HSBC said business and personal customers had been able to log on since Tuesday evening.In a video posted on Twitter,the bank’s chief operating officer,John Hackett,again apologised to customers.”We continue to monitor the service very closely ,and[6]are ready to respond should any issues arise ,but all the evidence is posi tive,”he said.But the bank,which has 17 million customers,has still not given a precise explanation as to what went wrong.It blamed the problem on a complex technical issue within its banking and mobile systems.Mr.Hackett said that no one’s personal data was put at risk during the failure,and that all customers would be compensated for losses caused by it.[7]The chair of the Treasury Select Committee,Andrew Tyrie,promised to question HSBC’s chief executive closely on why such failures keep occurring.5.What happened to HSBC’s online banking services?6.What d id the bank’s chief operating officer say to the public?7.What will HSBC probably face in the future?Conversation oneW:Good afternoon,sir.Anything I can do for you?M:Yes,I'd like to return this shirt I bought here about ten days ago for a refund.W:Well,could you please tell me what seems to be the problem for returning?M:[8]I washed it only once and it shrank at least two sizes!And now I can’t wear it.W:Oh,didn’t you follow the instructions?It’s on the label:to hand wash and dry it on low heat. M:How could I possibly know it ?The label is in French!W:I’m sorry about that.[9]But I can only help you to exchange for another one.M:I don’t want to exchange.I want my money back!W:Well,[9]I can give you a ten percent discount on another purchase.[10]But since the item you bought was on clearance,I’m afraid we can’t give you a refund.M:What?It’s a clearance item!I didn’t know that.W:I guess you didn’t read our advertisement.Here it is.And the information about the clearance sale is at the bottom.M:Where?That small print! I have to use an electron microscope to read those words.W:And anyway,you can only return items with the receipt within ten days,but unfortunately,that was yesterday in your case.M:[11] OK,OK,I give up.Take your shirt.You can take it to a pet store and sell it as a dog’s shirt.8.Why does the man want to return the shirt?9.What does the sales clerk offer to do for the man?10.Wh y can’t the man get a refund?11.How does the man feel in the end?Conversation TwoM:Excuse me,may I come in?W:Oh,yes.How can I help you?M:I am looking for the Economics Office.I looked for it all over the Arts Faculty Building,but I could only find the School of Accounting and Economic History.Is this the right place?W:Yes. This is the School of Economics.M:Oh good. Um, I'm a new student and I ‘m looking for someone who could give me some advice.W: Well,I might be able to help .I lecture on that program.What do you want to know about? M:A few things.First ,how many lectures do I have to attend a week?W:Well,[12]the Economics course is a double unit so there are two lectures a week and one tutorial. The lectures are scheduled for Monday and Thursday.M:] What time?W: Let me see...[13]You know this information is all in the handout that you should have received yesterday at the orientation .M: [13]Oh, I didn't know about that...no one told me...W: Never mind. [14]Now,there’s going to be a lecture at four this afternoon.M:[14] Four's a bit late. I've a part- time job starting from thirty.W: Well, you can't be in two places at one time,and [15]attendance is necessary. We expect at least 90% attendance at this university.M:90%!That’s high.[15]Is it compulsory?W:[15]Yes ,it is.We’re pretty stri ct about it ,actually.M:And what times have been set down for the tutorials--do you have that information?W:It's a well attended course, so there's a number of tutorial times. Monday, Wednesday and Friday, all at 9 a.m. Yours will be allocated at the first lecture.M: Can I choose the time?W:Maybe not. You'll have to talk to Dr.White,the lecturer on the course.M:OK.Thanks a lot for the information.12.When are the Economics lectures scheduled?13.What did the student miss yesterday?14.Why does the student find the four-o’clock lecture a bit late?15.What can we learn about the attendance rule?Section CPassage1The motor vehicle has killed and disabled more people in its history than any bomb or weapon ever invented.[16]Much of the blood on the street flows mainly from uncivil behavior of drivers who refuse to respect the legal and moral rights of others. So the killing on the road may be regarded as a social problem.In fact,the enemies of society on wheels are rather harmless people-just ordinary people acting carelessly,you might say. But it is a general truth both of law and common morality that carelessness is no excuse when one's actions could bring death or damage to others. A minority of killers go even beyond carelessness to total negligence .Researchers have estimated that as many as[17] 80 percent of all automobile accidents can be attributed to the psychological condition of the driver. Emotional upsets can distort (扭曲) drivers' reactions, slow their judgment, and blind them to dangers that might otherwise be clear. The experts warn that it is necessary for every driver to make a conscious effort to keep one's emotions under control.[18]Significant legal advances have been made towards safer driving in the past few years. Safety standards for vehicle have been raised both at the point of manufacture and through periodic road-worthiness inspections. In addition,speed limits have been lowered. Due to these measures,the accident rate has decreased. But the accident experts still worry because there has been little or no improvement in the way drivers behave. The only real and lasting solution,say the experts,is to persuade people that driving is a skilled task requiring constant care and concentration. Those who fail to do all these things present a threat to those with whom they share the road.16.Why are traffic accidents regarded as a social problem?17. Why does the passage mention the psychological condition of the drivers?18. What legal measures have been taken towards safer driving in the past few years?19.What is the main purpose of the passage?Passage 2Until recently,a tomato was just a tomato.[20]But now scientists have begun to change the genes of plants in laboratories, so it is not as easy to know when tomatoes are pure tomatoes.[20]That is true with many other vegetables and fruits。

Model test 1Air pollutionPeople nowadays have realized the serious problem of the air pollution caused by the car. One way to get rid of the polluted car is to design a car that does not pollute. That is what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this filed has been slow. Another way is to take the place of the car engine something else. Inventors are now working on steam cars as well as electric cars.Mini-lectureIf you are a college student in the United States, you are most likely to live in dorms. You don’t have a lot of choice when it comes to where you’re going to live. You will probably be asked to fill out a form indicating your housing choices. You can list your ideal dorms on campus (If you’ve visited or done some research), but there's no guarantee that you’ll end up there. Here are a few examples of the different types of college dorms or living arrangements you might encounter. The first type is all first year. Some dorms are set aside for first-year students only. The benefit is no upperclassmen ticked off by all the noise and chaos and you get to meet first-year students who share the similar experiences and feelings as you do everyday.The second type is single gender. There tend to be fewer all-male dorms than all-female. The disadvantage of a single-gender dorm is the fun factor. It’s simply more exciting to be in a coed dorm. Also. Coed dorms eliminate the mystique of the opposite sex. When you’re l iving with both guys and girls, everyone becomes just another person in the hallway.Unlike single gender for the whole building, single-gender floors are coed, but split the girls and boys up by floor. Depending on dorm rules, you may or may not be able to mix after certain hours.Then there is coed by room. Many dorms are coed by room girls and boys sharing walls but not rooms. Exciting at first, yes. However, this excitement can quickly turn sour when romantic relationships in the dorm go bad.The quiet-floor dorms set aside quiet floors where it’s easier to study. The fear is often that the resident on these floors are uptight and won’t party, but that’s not always the case. They just don’t want the party in their faces. However, quiet is relative to t he listener, and many people will find these floors noisy, especially if the rules aren’t well enforced.Special focus. Some campuses offer special dorm floors, such as those for students with an interest in majoring in music or languages, or are dedicated to earning academic honors. International dorms. Some college have dorms specially for students from other countries. Domestic students are allowed to live in these dorms too, but priority is given to those students coming from abroad.These are the most common types of dorm in American colleges or universities, and there are usually different rules in different dorms. But here are some common dorm rules that many colleges have.First, no alcohol. As is stated by the US law, the minimum legal drinking age is 21 and so it is illegal for anyone to drink alcohol under the age of 21. some dorms allow students who are over 21 to have alcohol in their rooms. At a first year, you are probably not over 21.Second, no fire hazards. These include candles, cigarettes, portable heating units, and sometimes irons. Some dorms still have smoking rooms, but this is becoming less common.Third, no unruly conduct. In other words, no fighting, destroying dorm property, setting off fire alarms… you get the idea.No appliances. Some dorms have rules about what kinds of kitchen items you can bring. Some only allow low-wattage microwaves and coffeemakers, and others don’t allow anything, not even a little fridge. Check with your dorm before you bring any appliances.No loud music or voices at night. Quiet hours generally start at 10 or 11 p.m. No loud music or voices after this time.Conversation 1M: Tina, I’m reading an article and just run across a term “the Greek System”. What is that?W: Oh, the Greek System is a very unique part of American college education. Most American colleges have these students organizations on campus. A boy’s group is called a fraternity which means brotherhood, and a girl’s groups is called a sorority. These fraternities and sororities have the ir own houses on campus. Collectively, these groups are called the “Greek System,” because each house is named after two or three letters of the Greek alphabet.M: So they are student organizations. What do they do?W: Well, there are different kinds of them. There are social Greek organizations, as well as those dedicated to a particular profession, such as medicine, law, engineering, or journalism. Also. Greek organization do a lot of community service: they raise money for charities, volunteer in soup kitchens and for other community organizations, and organize food drives on campus.M: Hmm I see. Why do students join these groups?W: There are many reasons to go Greek, “to go Greek” means to join a fraternity or sorority. For example, statistics show that there is a lower dropout rate among Greek students than non-Greek students. Also, once you join the Greek system, you immediately become part of a big community. There are lot of events offering you leadership opportunities, which will serve you well later in life. The community service will also add credits to your resume. These events are great resume builders, and employers see participation in Greek organization as a plus. Among other things, it means that you have some measure of discipline and that you managed to maintain decent grades in college despite your extracurricular commitments. There is established support structure, which helps students when they are going through hard times, including tutoring and academic support, and also networking opportunities after graduation. Besides, there are many parities, sports events, and nice houses with great cooks.M: Wow, that does sound fun!W: But of course, there are also reasons not to join a Greek organization. There are dues and fees, which can add to your financial burden. You also may not be the “frat type,” and prefer to go it alone. After all, you’ll be able to find friends even if you don’t join a house. While it can be tough to be an independent on a campus that’s mostly Greek, but there is no obligation to join.M: I see. Thank you for the explanation.W: You are very welcome.Q1: Which of the following statement is true about Greek System?Q2: The Greek organization have the following kinds EXCEPT?Q3: Which does the phrase “to go Greek” mean?Q4: Which of the following is NOT one of the reasons for joining the Greek organization?Q5: Which of the following is one of the reasons for not joining Greek organizations?Conversation 2W: Good morning! What can I do for you?M: Good morning! I want to open a bank account.W: No problem. Please fill out this form first. And may I have a look at your driver’s license or personal ID card?M: I don’t have a local driver’s license yet. I just arrived from Britain last week. But I have my passport with me. Here you are.W: Thanks. Would you like to open a checking account or savings account?M: I think I’ll do both.W: Great. And how much would you like to open your account with? We usually ask for a minimum sum of 10 dollars.M: Well I’m going to deposit 360 dollars into my checking account t start with. Also I need to transfer money to my account in Britain to pay back my student loans on a regular basis. In fact, I wanted to ask you about that. What’s the best way to do it?W: It depends on which bank you are with.M: It’s Bank of England.W: Ok, I will check that in a minute. If we have links with them, we can do the direct transfer. It’s not a big problem either way. By the way, would you also like to apply for a credit card? When you link the credit card with your checking account, you don’t need to worry about paying the money back every month. It will do automatically.M: That sounds good.W: OK, let’s see. How often would you like to receive statements?M: I haven’t really thought about it. What’s the usual thing?W: It’s up to you. Some people like it weekly.M: Oh no. That's too often. Can I have them sent once a month?W: Yes, that’s fine. Do you want to have the paper statement sent to your mailbox or just through email?M: I think just email will do. Let’s save the paper and go green.W: Great! Email statements sent monthly. Is there anything else?M: I was thinking of registering for your Internet service.W: Oh yes. Do you mind coming with me to the desk over there. I can guide you through the steps to activate online banking. I can’t do it on the computer at the counter here.M: Of course. No problem.W: Let me first input your information here, as I already have it for opening. Now, please take a look and confirm that all the information is correct.M: Let me see. Hmmm… yes, everything is correct. Thank you.W: Now please set up a password that contains at least 8 characters of both letters and numbers. M: OK… done!W: Would you like to receive the information about the bank and other services, insurance, loans, anything like that?M: I don’t think so, thanks.W: that’s ok, then.Q6: Which personal identification document does the man provide?Q7: Which account does the man NOT open?Q8: How does the man want to have the bank statements sent to him? Q9: What’s the password requirement for the online banking account? Q10: Which of the following statement is true?。

torch里model()用法
torch里model()用法在PyTorch深度学习框架中,`model()`是一个用于定义和构建神经网络模型的方法。
该方法可以用多种方式来使用,以适应不同的模型结构和需求。
本文将介绍`model()`方法的基本用法,并提供一些示例以帮助读者更好地理解和应用。
一、`model()`方法的基本用法在PyTorch中,我们可以通过继承`nn.Module`类来定义自己的神经网络模型。
在定义模型结构时,我们需要实现`__init__()`和`forward()`两个函数。
其中,`__init__()`函数用于初始化模型的结构和参数,`forward()`函数用于定义模型的前向传播过程。
在使用`model()`方法时,我们首先需要创建一个模型对象,如`model = MyModel()`,其中`MyModel`是我们定义的模型类。
然后,我们可以调用`model()`来完成模型的前向传播计算。
具体使用方法如下所示:```pythonimport torchimport torch.nn as nn# 定义模型类class MyModel(nn.Module):def __init__(self):super(MyModel, self).__init__()# 定义模型的结构和参数self.conv1 = nn.Conv2d(3, 16, kernel_size=3, stride=1, padding=1) self.relu = nn.ReLU()self.conv2 = nn.Conv2d(16, 32, kernel_size=3, stride=1, padding=1) self.fc = nn.Linear(32*8*8, 10)def forward(self, x):# 定义模型的前向传播计算x = self.conv1(x)x = self.relu(x)x = self.conv2(x)x = self.relu(x)x = x.view(x.size(0), -1)x = self.fc(x)return x# 创建模型对象model = MyModel()# 构建输入数据inputs = torch.randn(1, 3, 32, 32)# 完成前向传播计算outputs = model(inputs)```上述示例中,我们首先导入了`torch`和`torch.nn`模块,并定义了一个名为`MyModel`的模型类,该类继承自`nn.Module`类。
torch里model()用法
torch里model()用法PyTorch是一个流行的深度学习框架,它提供了许多方便的功能和工具,使开发人员能够更轻松地构建和训练神经网络。
在PyTorch 中,model()函数是一个重要的工具,用于创建和加载模型。
本文将介绍torch中model()的用法,包括其基本概念、创建模型、加载模型等。
一、model()的基本概念在PyTorch中,model()函数用于创建和加载模型。
它接受一个模型类或一个已经定义好的模型实例作为参数,并返回一个模型对象。
通过使用model()函数,开发人员可以轻松地创建和加载各种类型的神经网络模型,包括卷积神经网络(CNN)、循环神经网络(RNN)等。
二、创建模型要使用model()函数创建模型,需要先定义模型类。
模型类通常继承自torch.nn.Module,并实现其子类中的方法。
这些方法包括前向传播(forward())和其他必要的操作。
下面是一个简单的示例,展示如何使用model()函数创建一个简单的全连接神经网络:```pythonimport torch.nn as nnclass SimpleModel(nn.Module):def __init__(self, input_size, hidden_size,output_size):super(SimpleModel, self).__init__()self.fc1 = nn.Linear(input_size, hidden_size)self.relu = nn.ReLU()self.fc2 = nn.Linear(hidden_size, output_size)def forward(self, x):x = self.fc1(x)x = self.relu(x)x = self.fc2(x)return x```要使用上述模型类创建一个模型对象,可以使用model()函数:```pythonmodel = torch.nn.model(SimpleModel, input_size=784, hidden_size=500, output_size=10)```这将创建一个SimpleModel类的实例,并将其传递给model()函数。

机器学习中的目标检测与卷积神经网络模型参数调优方法及实践应用案例
机器学习中的目标检测与卷积神经网络模型参数调优方法及实践应用案例目标检测是机器学习领域中一个重要的任务,它被广泛应用于计算机视觉、图像处理、自动驾驶等众多领域。
而在目标检测的方法中,卷积神经网络(Convolutional Neural Networks,简称CNN)是目前被广泛使用和研究的深度学习模型。
在机器学习中,模型参数调优是十分关键的一步,它决定了模型的性能和泛化能力。
而调优卷积神经网络模型参数,尤其是用于目标检测的模型参数,是一个挑战性的任务。
本文将介绍一些常用的调优方法,并结合一个实践应用案例进行讲解。
在目标检测任务中,常用的卷积神经网络模型有Faster R-CNN、YOLO、SSD 等。
这些模型包含了许多参数,如学习率、批量大小、网络结构等。
在调优这些参数前,首先需要了解模型的性能指标和训练数据。
对于目标检测的性能指标,常见的有精确度(Precision)、召回率(Recall)和F1-score。
精确度是指被检索到的相关样本在所有检索到的样本中的比例,召回率是指被检索到的相关样本占所有相关样本的比例,F1-score是精确度和召回率的调和平均数。
训练数据则需要包含正样本和负样本的标签,用于模型的训练和评估。
针对模型参数调优,一种常用的方法是网格搜索(Grid Search)。
网格搜索将给定参数范围的所有组合都进行尝试,并通过交叉验证选择最佳的参数组合。
这种方法的优点在于简单直观,但其缺点是计算资源消耗大且耗时。
另一种常用的方法是随机搜索(Random Search)。
与网格搜索相比,随机搜索通过设置参数的分布范围,在参数空间中随机选择参数组合进行尝试。
这种方法相对于网格搜索更加高效,而且能够在有限的计算资源下得到较好的结果。
除了这些传统的调优方法,还有一些高级的优化算法也被广泛使用。

Today, we’ll talk about closeness and personal space. Every culture has different levels of physical closeness appropriateto different types of relationship, and individuals learn these distances from the society in which they grew up. When someone violates an appropriate distance, people may feel uncomfortable or defensive. Their actions may well be open to misinterpretation.In Western society, four distances have been defined according to the relationship between the people involved. They are intimate distance, personal distance, social distance, and public distance. These four distances are associated with the four main types of relationship-- intimate, personal, social and public.Now we’ll talk about the four personal distances one by one.First, we’ll begin with intimate distance. Intimate distance ranges from close contact, such as touching, to 45cm. In British society, it tends to be seen as an inappropriate distance for public behaviour and entering the intimate space of another person with whom you do not have a close relationship can be e_tremely disturbing.Ne_t, let’s look at the second type of distance, personal distance, which ranges from 45cm to1.2m. The far phase of personal distance is considered to be the most appropriate for people holding a conversation. At this distance it is easy to see the other person’s e_pressions and eye movements, as well as their overall body language. Handshaking can occur within the bounds of personal distance.OK, let’s move onto the third type of personal distance, social distance, which covers the range from 1.2m to 3.6m. This is the normal distance for impersonal business, for e_ample working together in the same room or during social gatherings. Seating is also important; communication is far more likely to be considered as a formal relationship if the interaction is carried out across a desk In addition, if the seating arrangements are such that one person appears to look down on another, an effect of domination may be created. At a social distance, speech needs to be louder and eye contact remains essential to communication, otherwise feedback will be reduced and the interaction may end.Finally, the last type of personal distance is public distance, which ranges from 3.7m to 4.5m. Teachers and public speakers address groups at a public distance. At such distances e_aggerated non-verbal communication is necessary for communication to be effective. Subtle facial e_pressions are lost at this distance, so clear hand gestures are often used as a substitute. Larger head movements are also typical of an e_perienced public speaker who is aware of changes in the way body language is perceived at longer distances.OK, today we’ve taken a brief look at the four personal distances associated with four main types of relationship. It is worth noting that these distances are considered the norm in Western society. Understandingthese distances allows us to approach others in non-threatening and appropriate ways. We can understand how others feel about us, how they view the relationship and, if appropriate, adjust our behaviour accordingly. SECTION B CONVERSATIONS Conversation One1.

You are in my American History 201 class, right? How can I helpyou today?M: It’s about my term paper. I know it’s due ne_t Monday, but I was hoping... I don’t think I can getit done by then. Could I please turn it in by the end of ne_t week instead?I have a really good e_cuse.W: Oh, I’m sure you do! I’ve been teaching 33 years. Do you know how many e_cuses I’ve heard?\papers due on the same day!\favorite was a student who told me she \ was due. It’s amazing she remembered to come to class.M: I didn’t forget, madam. I’ve been working on the paper, really! Here, I brought my outline and arough draft. It’s just that... Well, a lot of things have been going on in my life, and I’m having trouble managing things.W: I see. You know, I assigned that paper four weeks ago, and I’ve been reminding students about itin each class. So, tell me your story. What’s happening in your life? M: First, about two weeks ago, my roommate found out his mother was real sick. So he’s beenreally upset, and, uh,well, I went home with him for a couple of days to see his mom. That caused me to miss biology lab, and I have a huge biology final coming up on Tuesday that I really need to study for this weekend. Then I got the flu last week, and missed a day of class. I tried to workon your paper that day, but I really felt horrible...W: OK, I can understand that. I’m glad that you’re helping your roommate through a tough time.That’s more important than school work. But all this seems to have happened recently. What about the two weeks after I first assigned the term paper?M: I guess I didn’t use that time very well. I kind of put off getting started on it.W: Yes, you did. You know, if I had a dollar for every time I’ve heard a student say that...M: I’m sorry, Professor. I’ve learned my lesson. If I had spent just a little bit of time each week onthe paper, I could have had it done on time. I know now that I need to plan for une_pected things.W: You seem like a bright, conscientious young man. So I’ll tell you what. This time you can turn inyour paper no later than 9 a.m.Friday, right here on my office desk. M: Thank you, Professor! You bet I will.Questions 1-5 are based on Conversation One.1. Why does the man visit the woman?2. What is the man’s e_cuse?3. According to the man, what happened to his roommate?4. What lesson has the man learned from talking to the woman?5. What does the woman think of the man?Conversation TwoM: Hi! Welcome to WebWare. Sit down please. W: Thanks, nice to see you again.M: You too. So, you said you wanted to come in and have a chat with me before you start yourwork here. Tell me about it.W: Yeah, I just want to have a look round and ask a few more questions. I’m wondering whether itis okay for me to do so.M: Of course, just fire away with your questions!W: Well, first of all, I was surprised when I received the e-mail about the offer. Thank you fortrusting me, and I am delighted to receive the job offer... M: Good! And we are delighted to offer it to you.W: But... before I sign the contract there are one or two specifics I want to talk about. M: Ok... \W: Well. I read from your last e-mail that there is a pay scale, instead of a fi_ed salary. Is that right? M: Yes, you’re quite right about it. As a new employee in our company, you’d be at the lower end ofthe pay scale. And of course, things get changed later when you continuously bring contribution to the company.W: But taking my e_perience into account...M: Well, you haven’t had that much e_perience-- we see you as an investment...W: But that salary would only be a little more than I’m making now. So, instead of asking for ahigher level on the pay scale, I thought this could be compensated by adding certain bonuses, for instance if I make certain sales targets, or even break them, I would be looking for a good cash payment, or stock options in the company. Would it be possible?M: Well, that is something we sometimes offer to senior members of staff, but to show good faithI’ll provisionally offer you the bonus scheme, but I’ll have to okayit with Philip first. W: That’s fine. One more thing, I also see there are 25 days holiday. M: Yes. That’s standard.W: It’s not very much for a high pressure job though...M: I’m sorry I can’t offer you any more holiday. Only the staff who work here for over three yearscan get e_tra days, so you will get more holiday after you work here for a longer time.W: No, I don’t mean that. But I was wondering if I could delay the start date-- so instead of startinga week from now, as we discussed, I could start in a month’s time? M: You’re a tough negotiator, Madison! W: That’s one of the reasons you hired me!M: Yes, of course. Okay, I think we can do that. I’ll look forward to seeing you in a month, andearning those bonuses!Questions 6-10 are based on Conversation Two. 6. Why does the woman go to see the man?7. What does the man say about the pay scale in his company? 8. What requirement does the woman make about the salary? 9. What is the holiday policy in the company? 10. What does the man think of the woman?。
模型拟合指标
模型拟合指标
模型拟合指标是用于评估训练模型的性能,它可以帮助我们理解模型是否有效地捕捉到了数据中包含的信息,以及模型对新数据的泛化能力。
一般来说,模型拟合指标有三种:准确率、召回率和F1得分。
首先,准确率是衡量模型识别正确类别的比例,也就是真正例与所有预测正例之间的比率。
它可以被定义为:准确率 = 正确预测的样本/总样本数
召回率是衡量模型检测出正确类别的比例,也就是真正例与所有正例之间的比率。
它可以被定义为:
召回率 = 正确预测的样本/所有正例样本的总数
F1得分是准确率和召回率的调和平均数,它可以被定义为:
F1得分 = 2*(准确率*召回率)/(准确率+召回率)
准确率和召回率都是有限的,不可能同时达到最大值,而F1得分是两者的综合,能够反映出模型的整体性能。
当我们使用这三个模型拟合指标时,必须注意到,不同的应用场景会对这些指标产生不同的影响,因此,我们在选择指标时要根据不同的应用场景进行选择。
例如,在垃圾邮件检测的应用场景中,我们更关注模型的准确率,
因为我们不希望将正常邮件误认为垃圾邮件,而在欺诈识别应用场景中,我们更关注模型的召回率,因为我们需要尽可能多地检测出欺诈行为。
总之,模型拟合指标是评估模型性能的重要指标,它可以帮助我们更好地理解模型的表现,以及模型对新数据的泛化能力。
在选择模型时,我们要根据不同的应用场景来选择合适的模型拟合指标,以便对模型的性能进行有效评估。
model.score函数中的参数
model.score函数中的参数
在sklearn机器学习库中,model.score函数是用来评估模型在测试集上的表现。
这个函数的参数通常只有一个,即X_test,表示测试集的数据。
具体来说,X_test是一个数组或者列表,包含了测试集的数据。
这个数据需要与训练数据X_train格式一致,且特征顺序需要相同。
score函数返回的是模型在测试集上的得分,这个得分通常是一个介于0和1之间的值,表示模型在测试集上的准确率。
举个例子,如果我们使用逻辑回归模型训练了一个二分类问题,那么score函数返回的就是模型在测试集上的准确率,即模型预测正确的样本数占总样本数的比例。
需要注意的是,score函数只在模型有predict方法的情况下可用,因为score函数是通过模型预测测试集的结果来计算得分的。

But as more young people go to university in the UK, will those who decide to call it a day after A-levels find this decision proves a costly one?Students considering university might be put off by the prospect of higher tuition fees, a heavy student debt and years more studying. A review into higher education funding due in the autumn might recommend students pay more. But graduates can expect to earn 100,000 more over their working life after tax than teenagers who get a job after A-levels, according to the government.It still wants to reach a situation where 50% of people aged 18 to 30 participate in higher education. In 2007 - 2008, the participation rate reached 43. 3% . UK graduates can expect to earn even more than the government suggests, gaining on average 157% more than non-graduates, according to the Organization for Economic Co-operation and Development (OECD).Analyst Andreas Schleicher says improved graduate job prospects have a knock-on effect for the wider economy. "This is not simply a zero-sum game where those with university degrees are pushing out those without degrees from a fixed set of jobs."Countries that have done well in raising the proportion of highly-skilled workers have also seen better employment prospects for the lower skilled as job opportunities filter down, OECD data suggests "Not all courses equal. "But graduates' prospects of gaining the highly-skilled jobs depend on the university they go to and the course they do, according to John Philpott, chief economic adviser at the Chartered Institute of Personnel and Development." There will be a gradual realization that not every degree is of equal value in market terms," he says. He believes students need better information on the "likely level of pay" that could follow a particular course and that they will consider increasingly the "return" on their degree.For undergraduate Alex Mbaya, in his final year at Queen Mary, University of London, these considerations were not uppermost in his mind when he started his pharmaceutical chemistry degree. "I just had a passion for science. I didn't really think about a career at the end. It was what I really wanted to do. I wanted to learn more and enjoy it," says the 23-year-old. He is convinced he will fare better in the jobs stakes because he has been to university. "It is true at the end of this degree I will have 28,000 worth of debt but having done science I am certainly one of the winners. I can go into finance or I can transfer to law or even stay in science," he says.Final-year student Sophie Richardson also took her French and linguistics degree because she was interested in the subject. Even with a debt of 36,000 the 22-year-old woman does not regret for her decision. "I think I will be able to get into a higher level of job than I would have without a degree," she said, "I hope so. "Best motivation? Her optimism does not seem misplaced. Ian Brinkley, associate director of the Work Foundation, says the "reward" graduates can earn has remained constant over the past 10 years. He believes this will continue, especially in sectors where demand is likely to be high, such as business services, IT, computer services and the creative and cultural sector.Courses in science, engineering, mathematics or computer-related subjects will attract greater financial returns than humanities or arts degrees, he says.University and Colleges Union general secretary Sally Hunt does not think a "graduate premium" is the best basis for deciding on a course. She says students should be encouraged to pursue what they have always wanted to do. She also fears the cost of university means some students are choosing a course because it is nearer home. "Universities are not just graduate factories turning out a ready supply for business—they are there to teach all sorts of things. Graduates are less likely to be involved in crime, they are less likely to be on benefits and less likely to be a burden on the NHS, and so the case for investing in students is clear."Friends madeWes Streeting, president of the National Union of Students, says going to university is about more than the financial rewards, including the network of friends made and the broader experience it brings. Although graduates are leaving university with record levels of debt, he says people should not be put off applying as they are likely to face a better economic outlook.The government is keen to point out that more people are at university than ever before. In 2008 - 2009, there were nearly 2. 4 million people in higher education in the UK compared with more than 1. 5 million in 1994 -1995.Higher Education Minister David Lammy said, "A degree is a strong investment which stands graduates in good stead for a long and successful career, giving them better prospects than those with lower qualifications." He says university is "not the only choice" and that more resources are being put into other training, including money to create jobs for long-term unemployed young people."Second-rate"But economist Mr. Philpott says, "The push for more graduates is partly based on the conception that it is good financially to get a degree and it has a social cache and the idea that people who don't get a degree are somehow treated as second-rate. That attitude will take some time to shift. "For those considering university, Mr. Streeting says, " My advice to young people is to think really carefully about what they want to do, what interests them, what excites them and what the best route is for them. "Second-year drama student Scott Austin Shaw does not need convincing about the merits of university. "You can learn a lot about yourself and what you want to achieve in life from the different people you meet and the different things you get involved in. I would stay forever if I could," he says.1.If there were no higher education funding cuts, ______ .A) university in England would be hit B) the cost for higher education would increaseC) a heavy debt would occur to students D) students would finish studying earlier2.Which goes against John Philpott in terms of obtaining a highly-skilled job?A)The university and the course matter a lot.B)The specific interest of a student matters a lot.C)The value in market terms of a degree matters.D)The better information of "likely level of pay" matters.3.Alex Mbaya's choice of pharmaceutical chemistry as his major is based on _____ .A) information on the "likely level of pay" B) a good "return" on this degreeC) strong passion for science D) the career after graduation4.Which of the following four subjects expects the worst "financial return" , according to Ian Brinkley?A) Foreign Language.

"Look before you (37)________ ," "Don't count your chickens before they're hatched," "(38)________ what you preach," and many other familiar sayings are the (39)________ of old fables. In almost all fables the characters are animals that have the (40)________ power of speech. One of the best known writers of fables was Aesop, who was a Greek slave. He had had no (41)________ about fable, but he knew a great deal about people and the way they (42)________ . Some of his stories were funny, but often they were bitter ( 43)________ on Greek life.Little is known about him. In fact, there is some question as to whether he lived at all. ( 44 )_________________________________________________________________________________.Anyway, whether a man named Aesop really lived is not very important. What does matter is that someone whose name may or may not have been Aesop gave us a great many fables. (45)_____________________ _____________________________________________________________________________________. Among the fables which are believed to have been told by Aesop are The Fox and the Grapes, The Wind and the Sun, and The Lion and the Mouse. (46)________________________________________________ ____________________________________________________________________________________. Part IV Reading Comprehension (Reading in Depth) (25 minutes) Section ADirections: .In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.Questions 47 to 56 are based on the following passage.Civil rights leader Martin Luther King Jr. 47 his famous "I have a dream" speech while President Barack Obama has made the Oval Office his own 48 .To varying degrees, each president puts his own imprint on this 49 workspace. Even the smallest change—Obama's penholder, for example—is closely 50 for symbolism.While recent presidents have each done a big 51 upon taking office, Obama decided against major redecorating.The table behind Obama's desk is full of family photos—a wedding picture, a picture from the day he announced for president and more—photos that he says 52 him "why I'm doing what I'm doing."There's now a bust (半身像) of King in the Oval Office, in addition to the March on Washington program that 53 hung on Obama's "wall of heroes" in his Senate office.Perhaps no room in the White House is more closely 54 with the presidency.As Obama on updating the look of the Oval Office, in came four pieces of pottery by 55__ ___ Native American artists, all on loan from the National Museum of the American Indian. Also new to the Obama bookshelves are three mechanical devices on loan from the National Museum of American History's patent(专利) collection; models for Samuel Morse's 1849 telegraph register, John Peer's 1874 gear-cutting machine and Henry Williams' 1877 feathering paddlewheel for steamboats.White House curator (馆长) William Allman said the patent models fit Obama's 56 —his " interest in American history, his interest in technology and his interest in the creative spirit".Section BDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre. Passage OneQuestions 57 to 61 are based on the following passage.Are you a social butterfly, or do you prefer being at the edge of a group of friends? Either way, your genes and evolution may play a major role, U.S. researchers reported.While it may come as no surprise that genes may help explain why some people have many friends and others have few, the researchers said, their findings go just a little farther than that.7 "Some of the things we find are frankly bizarre (异乎寻常的)," said Nicholas Christakis of Harvard University in Massachusetts, who helped conduct the study."We find that how interconnected your friends are depends on your genes. Some people have four friends who know each other and some people have four friends who don't know each other. Whether Dick and Harry know each other depends on Tom's genes," Christakis said in a telephone interview.Christakis and colleague James Fowler of the University of California San Diego are best known for their studies that show obesity, smoking and happiness spread in networks.For this study, they and Christopher Dawes of UCSD used national data that compared more than 1,000 identical and fraternal (异卵的) twins. Because twins share an environment, these studies are good for showing the impact that genes have on various things, because identical twins share all their genes while fraternal twins share just half."We found there appears to be a genetic tendency to introduce your friends to each other," Christakis said. There could be good, evolutionary reasons for this. People in the middle of a social network could be privy (参与其中的)to useful gossip, such as the location of food or good investment choices.But they would also be at risk of catching germs from all sides—in which case the advantage would lie in more cautious social behavior, they wrote in the Proceedings of the National Academy of Sciences." It may be that natural selection is acting on not just things like whether or not we can resist the common cold, but also who it is that we are going to come into contact with," Fowler said in a statement.57.What can be inferred from the telephone interview on the researcher Christakis?A)One's genes decide how many friends he/she can have in social life.B)The intimacy between a person's friends relies on the person's genes.C)One's genes decide whether one is active in the social connection or not.D)The reason why the number of one's friends may vary from one to another.58.Which aspect are Christakis and his colleague James Fowler good at?A)Such common issues as obesity, smoking and happiness in social life.B)The style people interact with their friends in social connection.C)How genes may affect people's obesity, smoking and happiness.D)The transmission of obesity, smoking and happiness among friends.59.The genetic tendency mentioned in the passage ______ .A) is estimated to be reasonable B) could be explained by evolutionC) is relevant to genetic functions D) is possible to do good for people60.According to the research, what had people better do to benefit from socializing?A)Make great efforts to take part in social activities with higher alertness.B)Cultivate a better genetic tendency to introduce friends to each other.C)Make friends with each other more cautiously in the social network.D)Endeavor to decrease the potential risk that exists in the social network.61.What does "natural selection" in the last paragraph probably refer to?A)The genes a person is born with.B)Natural personality decided by genes.C)Gifts that the nature gives to a person.D)Evolutionary process one may experience.Passage TwoQuestions 62 to 66 are based on the following passage.Bosses in general can be a pain in the...well, you know, but a new study finds that your boss' gender can affect just how much pain he or she seems to inflict (使承受).Researchers at the University of Toronto used data from a national telephone survey of working adults in the United States and compared the stress levels and physical health problems of men and women working in one of three situations; for a lone male supervisor, a lone female supervisor, or for both a male and female supervisor.The study found that:Women who had only one female boss reported more psychological distress (such as trouble sleeping, difficulty focusing on work, depression and anxiety) and physical symptoms (such as headaches, stomach pain or heartburn, neck and back pain and tiredness) than women who worked for one male boss.Women who reported to a mixed-gender pair of supervisors also reported more of these symptoms than their peers who worked for a single male boss.Men who worked for a single supervisor, regardless of the supervisor's gender, had similar levels of distress. Men who worked for a mixed-gender pair had fewer mental and physical symptoms than those working for a lone male supervisor.The analysis, detailed in the September issue of the Journal of Health and Social Behavior, controlled for occupation, job sector and other workplace conditions, meaning the results were independent of these factors.The findings, specifically those of female subordinates with females bosses, contradict theories suggested by previous studies that demographic (人口统计学的) similarities between a boss and their subordinate would promote harmony in the work place, while demographic differences would create problems.The researchers speculated that these contradictions may stem from the stereotype (老套、模式化的见解)that it is more "normal" for men to be leaders and display the typical leadership characteristics. So while female subordinates may expect more "aggressive" traits from a male leader, they could expect more support from a supervisor who is also female than they actually get, said study co-author Scott Schieman.Women leaders who "act like men" in terms of society's unconscious expectations may be viewed more negatively, Schieman said. He and other sociologists suspect this was a situation faced by Hillary Clinton during the Democratic primary races.62.According to the passage, what can we learn about the findings of the study?A)People working for a female supervisor face more depression and physical symptoms.B)Men have fewer depression and physical symptoms than their female counterparts.C)Women facing a single boss have similar symptoms to their peers facing a mixed-gendersupervisor.D)Men facing a lone male supervisor experience more depression and physical symptoms.63.To remove certain disturbing effect, the research limited the interviewees _______ .A) workplace B) position typeC) job description D) working style64.According to the findings of previous studies, which of the following statements is true?A)Male supervisor is more capable of leading female workers into harmony.B)The mix-gender group is apt to promote their working efficiency.C)Boss and employee of the same gender cooperate better than mix-gender pair.D)Female worker is prone to come into collision with female boss.65.What is the conventional conception of men and women in workplace?A)Men leaders have greater working capacity.B)Women leaders are inclined to be more tolerant.C)Women supervisors have less grasp of the business overall than male leaders.D)Men are better at management than their female counterparts.66.What can be inferred from the last paragraph?A)Women leaders face more discrimination in career than men.B)Women leaders with male manner of acting are aggressive and not welcome.C)The potential concept of women leaders affects their career prospects.D)Hillary Clinton's dilemma in election could be attributed to her gender.Part V Cloze (15 minutes) Directions: There are 20 blanks in the following passage.
