Some students get so nervous before a test; they do poorly even if they know the material. Sian Beilock has studied these highly anxious test-takers.
Sian Beilock: “They start worrying about the consequences. They might even start worrying about whether this exam is going to prevent them from getting into the college they want. And when we worry,it actually uses up attention and memory resources. I talk about it as your cognitive horsepower that you could otherwise be using to focus on the exam.”
Professor Beilock and another researcher,Gerardo Ramirez,have developed a possible solution. Just before an exam,highly anxious test-takers spend ten minutes writing about their worries about the test.
Sian Beilock: “What we think happens is when students put it down on paper,they think about the worst that could happen and they reappraise the situation. They might realize it’s not as bad as they might think it was before and,in essence(本质上),it prevents these thoughts from popping up when they’re actually taking a test.”
The researchers tested the idea on a group of twenty anxious college students. They gave them two short math tests. After the first one, they asked the students to either sit quietly or write about their feelings about the upcoming second test.
The researchers added to the pressure. They told the students that those who did well on the second test would get money. They also told them that their performance would affect other students as part of a team effort.
Professor Beilock says those who sat quietly scored an average of twelve percent worse on the second test. But the students who had written about their fears improved their performance by an average of five percent.
Next, the researchers used younger students in a biology class. They told them before final exams either to write about their feelings or to think about things unrelated to the test.
Prefessor Beilock says highly anxious students who did the writing got an average grade of  B+,compared to a B- for those who did not.
Sian Beilock: “What we showed is that for students who are highly test-anxious,who’d done our writing intervention(排解),all of a sudden there was no relationship between test anxiety and performance. Those students most likely to worry were performing just as well as their classmates who don’t normally get nervous in these testing situations.”
But what if students do not have a chance to write about their fears immediately before an exam or presentation? Professor Beilock says students can try it themselves at home or in the library and still improve their performance.
小题1:Which of the following is TRUE?
A.The result in the math test agrees with that in the biology test.
B.In the first math test, students who sat quietly performed better.
C.In the second math test, students who wrote about their feelings did worse.
D.Some college students are highly anxious test-takers while others are not in the tests.
小题2:What may happen if students have the problem of test anxiety?
A.Test anxiety is sure to cause students to fail the test.
B.Test anxiety can improve students’ performance to some degree.
C.Students’ attention and memory resources run out when worried.
D.Students may not be admitted into their favorite college if worried
小题3:The result of the research suggests that ________.
A.proper amount of burden may turn out to be a good thing
B.facing the fears bravely may help one to achieve more
C.avoiding facing the problem may contribute to relaxation
D.taking no action before difficulty may result in success
小题4:What is the main idea of the passage?
A.It is important for students to overcome test anxiety.
B.Anxious students overcome test anxiety by writing down fears.
C.It is a common practice for students being worried before a test.
D.Being worried before tests does harm to students’ performance.

解析

试题分析:本文主要分析了如何避免考试焦虑症的影响,可以通过将自己的焦虑写下来,从而对克服考试焦虑症有了相当大的作用。
小题1:判断题。第一场考试中,文章并没有进行比较,B答案偷换概念。由Professor Beilock says those who sat quietly scored an average of twelve percent worse on the second test. But the students who had written about their fears improved their performance by an average of five percent.可知,第二场考试中,写了感受的学生表现的更好。故C错误。D选项文章并未提到当别的学生没在考试时,一些学生会变得焦虑。故D错误,由Prefessor Beilock says highly anxious students who did the writing got an average grade of B+, compared to a B- for those who did not. Prefessor Beilock说高度焦虑的学生考试前写下了他们的担忧,拿到了B+,而没有写的只拿到了B-,因此,考试前写下担忧的学生结果要好一些,与数学测试的结果是一致的,故本题答案为A。
小题2:细节题。由第二段的句子:when we worry, it actually uses up attention and memory resources.当我们担心时,事实上,它会消耗尽我们的注意力和精力,因此,可知,答案为C
小题3:推理判断题。文章倒数第三段的内容和第二段最后一句话表明勇敢的面对恐惧会让学生取得更好的成绩,选B。
小题4:主旨题。文章主要是讲了如何减少焦虑对考试的影响,方法是可以将恐惧,焦虑写下来,从而可以减轻这种影响,并通过两个实验进行了说明,所以选B,克服考试焦虑的方法是可以将担忧写下来。

试题【Some students get so nervous before a test; they do poorly even if they know the】;主要考察你对题材分类等知识点的理解。[详细]
举一反三
阅读下面短文,从各题A、B、C、D四个选项中,选出最佳选项。
Your brain isn’t a muscle, but you can treat it like one
Many people focus on physical fitness, but few know that brain fitness is also something you can work on. In fact, you can exercise your brain as often as you do to your arms or legs —and the results can be positive and empowering.
To improve your brain, you can’t simply repeat the same exercises over and over. Just as lifting a two—pound weight will stop challenging you, so will repetitive exercises such as crosswords or Sudoku. Once you master easy exercises, you must move on to harder ones in order to push your brain —like your muscles —to a new level.

The science behind brain training
Scientists once believed that your mental abilities were fixed in adulthood. Since studies have shown just the opposite, millions of people around the world have adopted the new practice of brain training. The most popular of these brain training products is made by the San Francisco—based Lumosity. Lumosity"s scientists with an experienced team of game designers have developed a fun,effective online brain training program that measures,tracks,and adapts to your progress,so you"ll always be challenged.
Promising studies on the effects of brain training
In a 2013 Stanford study,a treatment group of 21 breast cancer survivors used 12 weeks of Lumosity training to work on processing speed,mental flexibility,and working memory tasks. On average,those who trained improved on tests of these abilities,compared to a group that did not train with Lumosity.
There is even some evidence suggesting that Lumosity may be beneficial to normal,healthy adults. In a 2011 study by Lumosity and San Francisco State University researchers. 13 people who trained over 5 weeks improved working memory scores by 10%and attention scores by 20%.
Brain training is designed to meet real-life needs
The design of brain training is targeted at real-life benefits instead of improving game scores. Better attention,for example,can mean greater focus in the classroom or at an important business meeting. With improved processing speed,you might react and adapt faster to the demands of a busy life. And a better memory could mean stronger,longer relationships with the people closest to you.
小题1:We can learn from the passage that _________.
A.brain training speeds up the recovery of breast cancer
B.your brain is like a muscle because it gives you power
C.people"s mental abilities can"t develop after they grow up
D.Lumosity can measure,track and suit your level as you improve
小题2:Which skill may brain training not improve?
A.Better attention. B.A better memory.
C.Better writing skills.D.Higher processing speed.
小题3:What can we infer from the passage?
A.People should care more about physical health instead of mental health.
B.Brain training has been proved effective through scientific researches.
C.A bad memory is the only reason for weak relationships with people.
D.Playing online games is the best way of brain training.
小题4:What"s the best title for the passage?
A.Brain Training Makes a DifferenceB.Train Your Brain like a Muscle
C.Lumosity,Your Best ChoiceD.How to Train Your Brain

I got tired of living the life that everybody told me I “should” be living, so one day I decided to start living life in my own ways. Frustrated(挫败)with my job, I came home, put on my shoes, and just started running. It felt so good to be free. That first day I ended up running 30 miles without stopping. Yes, I had rediscovered my old passion ( 酷爱的事物) — and it felt so good that I set a goal to support myself and my family from my running alone.
I trained hard every day. Since I wanted to be the best I could be, I knew I would have to set some clear goals for myself. A couple of my goals were: run a 135-mile ultra-marathon(超级马拉松) across Death Valley, win the Badwater Ultra-Marathon, and run a marathon to the South Pole.
I had no idea how I was going to achieve these goals, but they certainly encouraged me to work hard. Today, I am really grateful to say that I have achieved all of them. Shortly after completing these goals, I set another goal: to run fifty marathons, in fifty states, in fifty days. Nobody had done anything like this before. To be honest, I was not quite sure if I could. But there was only one way to find out…so I just started training and preparing to give it my best try.
I completed that goal one year ago, and it felt great! But for me, life is not all about achieving goals. Sure, it feels good to succeed, but the greatest reward for me was learning more about myself and what I was able to do.
Only by stepping out into the unknown and stretching(使倾注全力) ourselves can we really discover what our true potential(潜能) is。
小题1:Which played an important role in the author’s success?
A.Setting goalsB.Learning from others.
C.Being honestD.Keeping on reading .
小题2:According to Paragraph 3, before achieving the goals the author felt _____________
A.very gratefulB.not quite confident
C.quite afraidD.not very satisfied
小题3:What does the underlined part “that goal” in Paragraph 4 refer to?
A.Win the Badwater Ultra-Marathon.
B.Run a marathon to the South Pole.
C.Run fifty marathons, in fifty states, in fifty days.
D.Run a 135-mile ultra-marathon across Death Valley.
小题4:The author probably agrees that____________.
A.life means achieving goals
B.success is the greatest reward
C.sports help develop our potential
D.everyone may have great potential.

Zoology(动物学)is the part of science that deals with the study of the animals’ growth, home and behavior. It has nothing to do with people, so many students are left wondering why they have to learn it.
Our nature includes not just humans but plants and animals as well. Everything in our environment is connected in a complex cycle. If you have a better understanding of how animals would behave and work with us, then you would value nature better.
Some animals are actually misunderstood by people like sharks and snakes. These creatures are thought of as human killers, and this is mainly because we don’t understand why they behave that way. In zoology you would be able to learn natural behavior as well as their homes so you would completely understand why they would behave in a defensive(防御的) manner when they seem to be threatened. Studying zoology would help people achieve clearness over the common myths we have on different wild animals.
Studying zoology would help people know the real facts about animals. One of the negative facts is the decreasing numbers of some species of animals. It makes people realize that there is a need for nature to be always balanced. We need animals to keep the balance in our environment and for humans to survive as well. It would help us learn the needs that animals lack and we can respond by thinking of solutions we can give to the endangered species of animals.
Modern progress is needed for a country to grow in terms of its economy; however, it should not force us to destroy our rainforests and oceans. People should realize that our modern lives should include the lives of the animals that live with us. They should not be contained in zoos but in their natural homes as well. We will learn that every living creature on the earth has the right to own a home and we need to fight for them to have permanent(永久的) homes.
小题1:According to the text, nature should be       .
A.left aloneB.treated seriously
C.taken for grantedD.taken lightly
小题2:It is implied in Paragraph 4 that animals play a role of        .
A.making our world beautifulB.protecting species of plants
C.providing food for humansD.keeping nature in balance
小题3:To animals, humans should act as        .
A.caretakersB.killersC.competitorsD.trainers
小题4:The best title for the passage may be “     ”.
A.The Ways of Protecting Animals
B.The Importance of Studying Zoology
C.The Introduction to Zoology
D.The Advantages of Learning Zoology

Every electronic gadget (小玩意) needs good memory. A music player stores songs, albums and playlists. A computer holds schoolwork and programs and remembers how far a player has advanced in his or her favorite game. Mobile phones store names, numbers and hundreds of texts.
Now, scientists in California say they have come up with a way to turn a living cell into a memory device.
It can store only one tiny bit of information, but it’s a start. In the future, a cell-based gadget might travel through the body and record measurements. The benefit to human health could be big: the right tool, for example, might record the earliest signs of disease.
Doctors, scientists and other curious people want to know what is happening inside the body, even at levels that can’t be seen by the naked eye. So far, there is no device small enough to travel through the bloodstream.
If normal machines won’t do the trick, perhaps biology will. Scientists who work in the field of synthetic (合成的) biology are trying to find ways to turn living things into human tools. In the case of the new memory device, bioengineers from Stanford University used the genetic material inside living cells to record information.
This genetic material consists of DNA. Found in nearly every cell, DNA carries all of the information that keeps a living thing alive.
In the new experiment, the researchers turned DNA from bacteria(细菌) into a switch. They “flip (翻转)” a small section of DNA. Then, using the same procedure (过程) , the scientists flip the section again—returning it into its normal structure.
Using these DNA switches, “We can write and erase DNA in a living cell,” bioengineer, Jerome Bonnet, explained to Science News.
It might take years before his team or others identity whether a DNA-based memory device might be practical. Right now, it takes one hour to complete a flip. That is far too long to be useful. Plus, a flipped section has a very small little memory—less than what a computer uses to remember a single letter.
“This was an important proof that it was doable,” Bonnet told Science News. “Now we want to build a more complex system, something that other people can use.”
小题1:What is the aim of listing the electronic things in the first paragraph?
A.To make the passage more fashionable.
B.To show how electronic things have memory.
C.To discuss things in detail.
D.To make the subject of the text more understandable.
小题2:What is possible future benefit of the cell-based gadget for people?
A.To detect disease at the earliest point.
B.To help improve the memory.
C.To help people build a body.
D.To replace many electronic gadgets.
小题3:What is the object being researched?
A. The cells of bacteria.         
B. The DNA of bacteria.
C. A section of bacteria.         
C. The nucleus of bacteria.
小题4:What do we know about a flipped section of DNA?
A.It has a very small memory.
B.It can function as a computer.
C.It has one letter in it.
D.It takes a day to complete it.

About ten men in every hundred suffer from color blindness in some way. Women are luckier, only about one in two hundred if affected in this matter. Perhaps, after all, it is safer to be driven by a woman.
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person can’t tell the differences between blue and green. In rare cases an unlucky man sees everything in shades of green--- a strange world in deed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions very small things called “cones”. These help us see in a bright day and tell the differences between colors. There are also millions of “rods”, but these are used for seeing when it is nearly dark. They show us shapes(形状) but not color. Some insects have favorite colors. Mosquitoes like blue but do not like yellow. A red light will not attract insects but a blue lamp will. In similar way human being also have favorite colors. Yet we are lucky. With the aid of cones in our eyes we can see many beautiful colors by day and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.
小题1:The passage is mainly about ______.
A.color and its surprising effects on drivers
B.women being luckier than man in that fewer of them are color blind
C.danger caused by color blindness
D.color blindness and how our eyes tell different colors and shapes
小题2:According to the passage, with the help of “cones” we can _____.
A.tell different colorsB.see in weak light
C.tell different shapesD.tell orange from yellow
小题3:Why do some people say it is safer to be driven by women?
A.Women are more careful.
B.There are fewer color blind women.
C.Women are fonder of driving than men.
D.Women are weaker but quicker in thinking.
小题4:Which of the following statements about color blind people is true?
A.Not all of them have the same problem in recognizing colors.
B.None of them can see deep red but all can tell blue from green.
C.None of them can tell blue from green but all can see deep red.
D.All of them are lucky enough to see everything in shades of green.
