常州市二十四中2017-2018学年上学期期中考试初二语文试卷一、积累运用4、仔细观察下面的漫画,完成下面的题目。

(3分)(1)请给这幅漫画拟个标题:5、某中学正在开展“预防电信诈骗”综合性学习活动,材料组已收集了一些材料,请你阅读这些材料,回答问题。

(4分)材料一:诈骗分子用网络虚拟电话冒充公安局的电话,打给退休在家的张女士,自称是某公安局的警官。

诈骗分子称张女士涉嫌犯罪,要求她把自己的银行存款打入指定的银行账户,以协助调查。

半信半疑的张女士通过查询得知,某公安局的电话与来电号码是一致的。

惊恐之下,张女士将十几万打入了对方提供的账户。

等她意识到被骗时,痛悔不已。

反诈骗专家说,公安机关执法期间要向老百姓了解情况时会当面询问当事人,不会电话要求你往银行帐户存钱。

近年来,这类案件令群众的损失每年高达上百亿元,许多受害者除了蒙受巨大的经济损失外,还承受着心理的痛苦。

材料二:电信诈骗是指诈骗分子通过电话、网络和短信方式,编造虚假信息,设置骗局,对受害人实施远程、非接触式诈骗,诱使受害人给犯罪分子打款或转账的犯罪行为。

受害者对这类案件了解不多,缺少警惕,容易轻信来历不明的电话,透露身份和银行卡信息,甚至向陌生人的账户存钱。

有些受害者接到这类电话,思想就被骗子控制了,不能及时询问亲友,或打电话给公安机关了解情况。

我们要通过电视、报纸、网络等渠道多了解这类骗局,提高警惕,增强防骗意识。

(1)请用简短的语句概括材料一的内容。

(2)由上述材料你能得出哪些预防电信诈骗小知识?6、默写。

(6分)(1)________________________,夜泊秦淮近酒家。

(2)东市买骏马,________________________,________________________。

北市买长鞭。

(3)体现龚自珍载着“浩荡离愁”辞官还乡,却仍关心国家的前途和命运的诗句是________________________,________________________。

Another thing of Green Island that people are interested in is its rocks in different shapes. “ Sleeping Beauty ” and “ Pekinese Dog ” are the two most strangely shaped ones. There are also other interests which one cannot miss. The green hills, blue sea, clear sky, and ocean gentle winds make a “ must” for you. l:From the article we know Green Island is.D. a dog of “ Sleeping Beauty ”(B )Nobody is happy all the time, but some people are really happier than others. Here are some tips for you to be happy.Make enough money to meet your basic needs: food, shelter; and clothing. In the US, that magic number is $40,000 a year.

Borrow money from family members ・C. How to make family members be happy.D. Stay close to friends and family.3.The passage is from ____________ .A. the InternetB. a magazineC. a newspaperD. a book review(C)When my family moved to America in 2010 from a small village in Guangdong, China, we brought not only our luggage, but also our village rules, customs and culture. One of the rules is that young people should always respect(尊敬)elders. Unluckily this rule led to my very first embarrassment in the United States.I had a part-time job as a waiter in a Chinese restaurant. One time, when I was serving food to a middle-aged couple, the wife asked me how the food could be served so quickly. I told her that I had made sure they got their food quickly because I always respect the elderly. As soon as I said that, her face showed great displeasure. My manager who happened to hear what I said, took me aside and gave me a long lecture about how sens让ive(敏感)Americans are and how they dislike the description "old". I then walked back to the table and apologized to the wife. After the couple heard my reason, they understood that the problem was caused by cultural differences, so they laughed and were no longer angry.In my village in China, people are proud of being old. Not so many people live to be seventy or eighty; and people who reach such an age have the most knowledge and experience・ Young people always respect older people because they know they can learn from their rich experience ・However in the United States, people think '"growing old" is a problem since "old" shows that a person is going to retire or that the body is not working well. Here many people try to keep themselves away from growing old by taking exercise, and women put on makeup, hoping to look young. When I told the couple in the restaurant that I respect the elderly, they got angry because this caused them to feel they had failed to stay young. I had told them something they didn't want to hear.After that, I changed the way I had been with older people. It is not that I don't respect them any more; I still respect them, but now I don't show my feelings through words.1.Jack brought the couple their food very fast because _________ .A. the manager asked him to do soB. he respected the elderlyC. the couple wanted him to do soD. he wanted more money2.What does the underlined word H embarrassment n mean in the first paragraph?A.尴尬B.拮据C.潦倒D.敬仰3.In the writer's hometown, ________ .A. people dislike being called "old” because they can't learn a lot from othersB・ many people reach the age of seventy or eightyC.people are proud of being oldD.the elderly are the first to get food in restaurants4.Which of the following is TRUE?A.The more Jack explained, the angrier the couple got.B.Jack wanted to show his feelings through words after his experience.C.The manager went back to the table and apologized to the couple・D.From this experience, Jack learned more about American culture.四、阅读和表达We need to be responsible for our environment. Being a frugal consumer (节俭H勺丫肖费者)is one way to help. But, what exactly does that mean?Use It UpYou can use things up instead of wasting them. Squeeze that last bit of toothpaste out of the tube. Use the last little piece of soap. Don't throw away any bits of the biscuit at the bottom of the box.Wear It OutYou do not always need to have new things. Suppose your sneakers have broken laces, but they still fit you. Repair them and wear them longer. You don f t have the latest iPhone until the old one doesn't work anymore・ Then you can get a new one・ Think twice before replacing something that still works.Make It DoWhen something you want is not on hand, look for something else that you already have to take 让s place. If you are packing your lunch for tomorrow and want a butter sandwich. You are out of butter. Have a cheese sandwich instead so that you can use all of the cheese. Learn to fix broken toys instead of just throwing them away. W让h a little thought, you can make something do, instead of buying something new.Do WithoutThink about all those things that you would like to have. Do you really need them? How long will you really play w让h that new toy you saw on TV? Making the things that we want uses up your world's resources(资源)・And, getting rid of the things we don't want any more takes up even more resources and space.%1.词汇A)根据句意,用所给词的适当形式填空1.Most ___________________ (south) cities in our country develops much faster than the other cities in the north.2.A human cell is ten times _______________ (tiny) than the width your hair.3.Have you booked the ___________________ (fly) tickets to Tokyo recently?4.What does the word _________________ (exact) mean?5.—Why do you think 让____________ (possible) for the lazy boy to pass the hard exam? -—Because he seldom puts his heart in anything he needs to do.B)根据中文提示,用所给词的适当形式填空。

The old name for Green Island was Huoshandao,meaning “fireburning island”. The island got its name because people on the island used to set up fires at night to help people who went fishing home. Another story goes that in the Qing Dynasty there was afire and most of the island’s trees and grass died. The coastline of the island is only 20 kilometers long,the tallest mountain is only 281 meters high and the island is only 15 km2,but it is attracting(吸引) a growing number of tourists.Green Island has a lot of interests that make it a place where people like to go:seaside,a clean white beach,green grasslands,seawater,hot springs,beautiful undersea sights,and a great many plants and animals. Another thing of Green Island that people are interested in is its rocks in different shapes. “Sleeping Beauty”and “Pekinese Dog”are the two most strangely shaped ones. There are also other interests which one cannot miss. The green hills,blue sea,clear sky,and ocean gentle winds make a “must”for you. 1:From the article we know Green Island is ________.A.very large B.281 meters longC.in the Indian Ocean D.33 kilometers from Taitung2:According to the two stories,people on Green Island used to ________.A.meet a lot of visitors B.set fires to get warmC.make a living by fishing D.cut down too many trees and grass3: The sight “Pekinese Dog”is ________ on Green Island.A.a cute living dog B.a rock like a dogC.a dog­shaped plant D.a dog of “Sleeping Beauty”(B)Nobody is happy all the time, but some people are really happier than others. Here are some tips for you to be happy.Make enough money to meet your basic needs: food, shelter, and clothing. In the US, that magic number is $40,000 a year. Any money you make beyond(超过) that will not necessarily make you happier. Once you make enough money to support your basic needs, your happiness is not affected by how much money you make.______________________________ Or move to where other members are-so you can see them more. Now, people follow jobs around the country and sometimes around the world. As a result, our relationships with our friends and family have a far greater impact (影响) on our happiness than our jobs do. So next time you think about moving, consider a place where most of your friends and families live.Find happiness in the job you have now. Many people expect the right job to change their level of happiness. But happiness research makes it clear that changing jobs can’t bring you happiness. If you want, you will make the best of any job. If you have good relationships withpeople, you won’t depend on (依赖) your job to give your life a greater sense of meaning. You will find it in your communication with the people you care about.If you are unhappy for a long time, you should ask an expert (专家) or a doctor for help. I hope you will be happy all the time.小题1:The writer wrote this passage mainly to _____________.A.make friends B.give advice on how to be happyC.put on an advertisement D.ask for help2:What is the topic sentence for the third paragraph?A.Ask family members for help. B.Borrow money from family members. C.How to make family members be happy. D.Stay close to friends and family.3. The passage is from ___________.A. the InternetB. a magazineC. a newspaperD. a book review(C)When my family moved to America in 2010 from a small village in Guangdong, China, we brought not only our luggage, but also our village rules, customs and culture. One of the rules is that young people should always respect(尊敬) elders. Unluckily, this rule led to my very first embarrassment in the United States.I had a part-time job as a waiter in a Chinese restaurant. One time, when I was serving food to a middle-aged couple, the wife asked me how the food could be served so quickly. I told her that I had made sure they got their food quickly because I always respect the elderly. As soon as I said that, her face showed great displeasure. My manager, who happened to hear what I said, took me aside and gave me a long lecture about how sensitive(敏感) Americans are and how they dislike the description “old”. I then walked back to the table and apologized to the wife. After the couple heard my reason, they understood that the problem was caused by cultural differences, so they laughed and were no longer angry.In my village in China, people are proud of being old. Not so many people live to be seventy or eighty, and people who reach such an age have the most knowledge and experience. Young people always respect older people because they know they can learn from their rich experience.However, in the United States, people think “growing old” is a problem since “old” shows that a person is going to retire or that the body is not working well. Here many people try to keep themselves away from growing old by taking exercise, and women put on makeup, hoping to look young. When I told the couple in the restaurant that I respect the elderly, they got angrybecause this caused them to feel they had failed to stay young. I had told them something they didn’t want to hear.After that, I changed the way I had been with older people. It is not that I don’t respect them any more; I still respect them, but now I don’t show my feelings through words.1.Jack brought the couple their food very fast because _______.A. the manager asked him to do soB. he respected the elderlyC. the couple wanted him to do soD. he wanted more money2.What does the underlined word ”embarrassment” mean in the first paragraph?A. 尴尬B. 拮据C. 潦倒D. 敬仰3.In the writer’s hometown, _______.A. people dislike being called “old” because they can’t learn a lot from othersB. many people reach the age of seventy or eightyC. people are proud of being oldD. the elderly are the first to get food in restaurants4.Which of the following is TRUE?A. The more Jack explained, the angrier the couple got.B. Jack wanted to show his feelings through words after his experience.C. The manager went back to the table and apologized to the couple.D. From this experience, Jack learned more about American culture.四、阅读和表达We need to be responsible for our environment. Being a frugal consumer (节俭的消费者) is one way to help. But, what exactly does that mean?Use It UpYou can use things up instead of wasting them. Squeeze that last bit of toothpaste out of the tube. Use the last little piece of soap. Don't throw away any bits of the biscuit at the bottom of the box.Wear It OutYou do not always need to have new things. Suppose your sneakers have broken laces, but they still fit you. Repair them and wear them longer. You don't have the latest iPhone until the old one doesn't work anymore. Then you can get a new one. Think twice before replacing something that still works.Make It DoWhen something you want is not on hand, look for something else that you alreadyhave to take its place. If you are packing your lunch for tomorrow and want a butter sandwich. You are out of butter. Have a cheese sandwich instead so that you can use all of the cheese. Learn to fix broken toys instead of just throwing them away. With a little thought, you can make something do, instead of buying something new.Do WithoutThink about all those things that you would like to have. Do you really need them? How long will you really play with that new toy you saw on TV? Making the things that we want uses up your world's resources(资源). And, getting rid of the things we don't want any more takes up even more resources and space.五、词汇A)根据句意,用所给词的适当形式填空1. Most __________________(south) cities in our country develops much faster than the other cities in the north.2.A human cell is ten times _______________(tiny) than the width your hair.3.Have you booked the ___________________(fly) tickets to Tokyo recently?4.What does the word _________________(exact) mean?5.---Why do you think it __________________(possible) for the lazy boy to pass the hard exam?----Because he seldom puts his heart in anything he needs to do.B)根据中文提示,用所给词的适当形式填空。
