After silencing it, I remained in bed. My motivation to push ahead with my PhD was disappearing, which made it hard to face each new day. Continuing would risk a total breakdown. With anxiety, I decided to cease my PhD temporarily and take a 9-month position at a health care charity. Back when I looked for PhD positions, I was unclear what I wanted to study. For me, the degree mostly served as a means to an end, securing more interesting and higher-paid positions in the private sector than my master’s degree would unlock. So I wasn’t picky and reasoned a variety of projects that would provide the training and degree I wanted.In hindsight (事后想来), I should have been more selective. I ended up working on a project I was technically capable of completing but over time felt full of disappointment. The purely academic research was intellectually interesting, yet I struggled to see how it would make an impact on the wider real world.Some unexpected things amplified my trouble. I started my program in 2020, when meetings were virtual and in-person contact was actively discouraged, so I had few opportunities to form personal connections with co-workers. Research became my only focus, and when my interest in that faded, my project felt depressing.After only 1 month at the charity, it became clear that I’d made the right decision. My mental health improved and I found it easier to come into work. Things I did could matter and energize me after all —if I chose wisely. That was exactly what I needed and desired. After that realization, I decided I wanted to return to my PhD program and make changes. I told my teacher I wasn’t interested in the current research. To my relief, he was supportive, and we redesigned the project to better fit me. I will return to my program next month, optimistic that this time will be different. But if it doesn’t go as I hope, my charity experience has given me direction and confidence that I’ll live a satisfying life, with or without a PhD.4.What did the author view the PhD degree as at first?A.A struggle for new days.B.A breakthrough in his study.C.A way of getting a better job.D.A chance to build connections.5.Why did the author become disappointed at his project?A.It was of slight practical use.B.It failed to meet his social need.C.It showed an unpromising future.D.It had a high degree of difficulty.6.What does the underlined word “amplified”in paragraph 3 mean?A.Reflected.B.Caused.C.Solved.D.Increased.7.How did the charity work affect the author?A.It inspired him to face challenges.B.It helped him find a purpose in life.C.It fueled his enthusiasm for his program.D.It enabled him to make the right decision.I wanted to set myself the writing challenge of citing some of the many positive things about having a baby. It’s addressed to one person, but I hope that those who find themselves at a similar crossroads get help from it.To my friend A,All you ever seem to hear about parenthood is negative. I do not feel this. You create a new life in that child, and with that baby, you get a new life, too. When I became a mother, my own mother’s embrace, and my father’s, not to mention my extended family’s, have kept me going.We are used to hearing about how motherhood limits your life, less so about how it can expand it. I have always believed that life is fundamentally about human relationships, and having a baby has enhanced mine. Becoming a mother—and giving birth—has enhanced my feelings of solidarity with other women. Parenting has also allowed me to experience childhood again. I have always wanted to give someone else a childhood. My wide-eyed little boy is at the stage where he is simply in love with the world, and that love is thrillingly unconditional. It is a privilege to witness, and it makes me determined to maintain it for him as much as I am able to, because his laugh is the best sound that I have ever heard.A note about sleep: you will be OK-you’ve had enough wild nights to know you can cope. And you can get your body back, whatever that might mean to you. As for your career, it’s normal to worry. I speak only for myself when I say that I wish I had spent less time worrying beforehand about how I would write. I have far less time, now, but I’m still writing. Even a paragraph a day adds up to a novel, eventually. There is so much untapped joy and love there waiting for you, and I hope I’ve given you a small glimpse of some of it to hold on to.8.Who might be the intended audience for this article?A.Self-centered parents.B.Those fearing to have a baby.C.Broken-hearted friends.D.Those avoiding marriage.9.How does the author mainly make his arguments convincing?A.By explaining ideas.B.By quoting sayings.C.By comparing facts.D.By concluding opinions.10.Why does the writer give examples of her writing in the last paragraph?A.To show how successful she was as a writer.B.To note that where there is a will there is a way.C.To tell her friend that giving birth is a piece of cake.D.To persuade her friend not to worry about her career.11.Which column may the article be chosen from?A.Opinion.B.Headline.C.Health.D.Culture.When you ask people to judge others by their speech, a trend emerges: Listeners dislike disfluency. Slow talkers producing loads of ums and pauses (停顿) are generally perceived as less charming. But science tells us there may be even more to disfluency.Disfluencies do not occur in arbitrary positions in sentences. Ums typically occur right before more difficult or low-frequency words. Imagine you’re having dinner with a friend at a restaurant, and there’re three items on the table: a knife, a glass, and a wine decanter (醒酒器). Your friend turns to you and says, “Could you hand me the...um...” What would you assume they want? Since it’s unlikely that they will hesitate before such common words as knife, and glass,chances are you’ll pick up the decanter and ask, “You mean this?”This is exactly what we demonstrated through controlled eye-tracking studies in our lab. Apparently, listeners hear the um and predict that an uncommon word is most likely to follow. Such predictions, though, reflect more than just simple association between disfluencies and difficult words; listeners are actively considering from the speaker’s point of view. For example, when hearing a non-native speaker say the same sentence but with a thick foreign accent, listeners don’t show a preference for looking at low-frequency objects. This is probably because listeners assume non-native speakers may have as much trouble coming up with the English word for a common object, like a knife, as for unusual ones and can’t guess their intention.In another experiment, listeners were presented with an uncommon speaker who produced disfluencies before simple words and never before difficult words. Initially, participants displayed the natural predictive strategy: looking at uncommon objects. However, as more time went by, they gained experience with this uncommon distribution of disfluencies. Listeners started to demonstrate the contrary predictive behavior: They tended to look at simple objects when hearing the speaker say um.These findings represent further evidence that the human brain is a prediction machine: We continuously try to predict what will happen next, even though not all disfluencies are created equal.12.Which statement does the example in paragraph 2 support?A.Pauses usually follow uncommon words.B.Slow talkers tend to pause more.C.Fluent speakers are unlikely to pause.D.Active listeners only guess difficult words. 13.What does the author say about the non-native speakers?A.They can be understood easily.B.They actively put themselves in others’ shoes C.Their vocabularies are limited.D.Their disfluencies are a little less predictive. 14.What does the experiment in paragraph 4 show?A.Simple things are difficult in some cases.B.Listeners can adjust predictions accordingly.C.Distribution of disfluencies is changeable.D.Disfluencies in communication can be avoided.15.Which of the following can be the best title for the article?A.Pauses Coexist with Hesitation B.Human Brains Have the Power to PredictC.Active Listeners Simplify Talks D.Disfluency Says More than You ThinkEveryone is faced with problems at some point or the other. 16 The problems, however, become different when past strategies do not work and there is no obvious solution. This can cause anxiety and stress. However, all you need to do is remain calm and use a new, different method. Here are some easy ways to solve problems.Acknowledge that there is a problem. Many people refuse to acknowledge that there is a problem. They continue thinking everything will disappear on its own, so they fail to seek timely help. This does not help the situation in any way. 17Keep a journal. Keeping a daily journal is the best way to solve deeper problems that may be affecting your peace of mind. 18 Sometimes, just by writing down issues, you might get to see that a problem isn’t as big as you are thinking.19 Often, to solve a problem, you need to test your limits. You may have to take on certain challenges including learning something new to improve yourself. If you continue thinking of the problem as a threat and view yourself as a failure or a weak person, you will not be able to deal with the problem. Nevertheless, if you can see some benefits coming out of the problem, you will be in a better position to accept the challenge and learn something new.Seek help. 20 If you are still unable to solve the issue despite giving it much thought and attention, seek help from friends, colleagues, family or even professionals. A.Challenge yourself.B.Set achievable goals.C.Instead, it can make the problem bigger than before.D.So write down all the problems you are facing right now.E.Sometimes, certain problems can’t be solved on your own.F.So try to come up with at least 10 different solutions to a problem.G.Many problems can be solved by using methods we might have used before.二、完形填空While most teenagers spend the summer hanging out, Ke’Nyzjah Ferebee doesn’t join.Filling cake orders and updating her website 21 the 17-year-old senior high school student.

湖南省长郡中学2022-2023学年高二下学期普通高中学业水平合格性考试模拟试题学校:___________姓名:___________班级:___________考号:___________一、阅读理解Do you know what to do when there is an emergency? By calling the police, you can protect yourself and those around you.Call the police in all of the following emergencies:◆ A crime, such as a theft, especially if it is still in progress.◆ A car accident, especially if someone is injured.◆ Domestic violence, such as a child being mistreated.◆ Anything else that seems like an emergency.You may also call the police when you see something suspicious(可疑的)in your neighborhood:◆ Someone you don’t know is frequently walking around in your neighborhood. This could be a sign that the person is trying to break into a house.◆ Someone is trying to open the doors of a car. This could be a sign that the person is trying to steal the car.When you see something suspicious, do not suppose someone else has already called the police. People often hesitate to call the police for fear of danger. However, the police want to help prevent crime.What should you do when you call the police?◆Dial 911 (the U.S. emergency number; the number varies from one country to another—in China, you dial 110 to call the police). Stay calm when calling and give your name, address and phone number. Then, tell the person why you are calling (What happened? Where did it happen? When did it happen? Is it still in progress?). Follow any instructions you are given. For example, the dispatcher (调度员) might say, “Stay on the line,” or “Leave the building.”◆ If you dial the emergency number by mistake.do not hang up. Doing so could make the dispatcher think an emergency really exists. Instead,just tell the person that you called by mistake.Most police departments have a communication center. The communication center staffreach police officers by radio. Police officers carry headsets. like earphones, to stay in touch with the communication center.1.When calling the police, you DON’T need to give ______ to the dispatcher.A.your name B.your phone numberC.your ID card number D.some details of the emergency 2.What should you do if you dial the emergency number by mistake?A.Power off your smartphone.B.Hang up your phone at once.C.Tell the dispatcher you called by mistake.D.Go to a police station to explain your mistake.3.What do the communication center staff in police departments do?A.Monitor police officers.B.Answer emergency calls.C.Tell people what to do in an emergency.D.Reach police officers when there is an emergency.4.What is the purpose of the passage?A.To tell people when and how to call the police.B.To introduce a police officer’s general duties.C.To share the author’s experience of calling the police.D.To thank the police for trying to prevent crimes.Anderson Carey is 12 years old. One day, he saw a magazine article that interested him.It was about prosthetics(假肢), which can be used to replace a hand, arm or leg.The article said people are using 3-D printers to build these devices. Anderson thought this was very cool. He wanted to learn more about it. So Anderson talked to his science teacher, Dr. Holly Martin. He asked if they could build a prosthetic together. The timing(时机的把握) was perfect. Martin had just heard about a group called Enabling the Future. This group asks volunteers to help to build robotic arms and legs. The volunteers build them for people who share their stories on the website.Anderson and Martin looked through the website together. They decided to help a man from the country of Romania. His name is Cornel Crismaru, who lost his leg, hand and part of his arm.In February, Anderson and Martin got to work. Building the robotic arm was not easy. Anderson ran into some problems along the way. He had hoped to use a 3-D Printer at hisschool. One of the pieces for the arm was bigger than the size of the printer, though.Soon Anderson had an idea to solve this problem. He reached out to a 3-D printing company in Woodstock, Georgia. The company agreed to help. Anderson and Martin could use their big 3-D printers. After that, Anderson worked on the arm for about three months.Anderson and Martin sent the arm to Crismaru in May. In August, they received a notice. It is from Crismaru’s son. He thanked Anderson and Martin for their help.Martin said she hopes children and grown-ups who hear about Andersons projects will realize that it may be hard to change the world, but they can start with small acts.

如公元前645年,晋国被秦国打败,国君被俘,国内大臣借惠公名义“朝国人”,宣布了对土地的改革方案,即“作爱田”,并要求国人同心一致;公元前502年,卫灵公在晋国受辱,欲叛晋,为获取支持,便召集国人,讲述他受辱于晋的情况;公元前494年,吴国派人召陈国跟随伐楚,怀公拿不定主意,于是“朝国人”而问其所以。
