You have waited 45 minutes for the valuable 10 minutes’ break between classes. But when the bell for the next class rings, you can’t 36 how quickly time has passed.
If you are familiar with this 37 , you’ll know how time flies when you are having fun-and 38 when you are bored. Now scientists have 39 a reason why this is the case.
Scans have shown that patterns of activity in the brain 40 according to how we focus on a task. When we are 41 , we concentrate more on how time is passing. And this makes our brains 42 the clock is ticking more slowly.
In an experiment 43 by a French laboratory, 12 volunteers watched an image 44
researchers monitored their brain activity.
The volunteers were told to 45 concentrate on how long an image appeared for, then
46 the color of the image, and thirdly, study both duration and color. The results showed that 47 was more active when the volunteers paid 48 subjects.
It is thought that if the brain is 49 focusing on many aspects of a task, it has to 50 its resources, and pays less attention to the clock. 51 , time passes without us really 52 it, and seems to go quickly. If the brain is not so active, it concentrates its 53 energies on monitoring the passing of time. 54 , time seems to drag.
Next time you feel bored 55 , perhaps you should pay more attention to what the teacher is saying!

查看习题详情和答案>>The common cold is the world's most widespread illness, which is plagues(疫病) that flesh receives.
The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses(病毒) passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.?
During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet, showed no increased tendency to catch colds.?
In the Second World War prisoners at the notorious Auschwitz concentration camp(奥斯维辛集中营), naked and starving, were astonished to find that they seldom had colds.?
At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.?
If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains—taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.?
No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is to relieve the symptoms(症状).?
1. The writer offered _______ examples to support his argument.?
A. 4 B. 5 C. 6 D. 3
2. Which of the following does not agree with the chosen passage??
A. The Eskimos do not suffer from colds all the time.?
B. Colds are not caused by cold.?
C. People suffer from colds just because they like to stay indoors.?
D. A person may catch a cold by touching someone who already had one.
3. Arctic explorers may catch colds when ________.
A. they are working in the isolated Arctic regions?
B. they are writing reports in terribly cold weather?
C. they are free from work in the isolated Arctic regions?
D. they are coming into touch again with the outside world
4. The passage mainly discusses ________.
A. the experiments on the common cold
B. the fallacy about the common cold?
C. the reason and the way people catch colds
D. the continued spread of common colds
查看习题详情和答案>>When a group of children politely stop a conversation with you, saying: “We have to go to work now,” you’re left feeling surprised and certainly uneasy. After all, this is the 1990s and the idea of children working is just unthinkable. That is, until you are told that they are all pupils of stage schools, and that the “work” they go off to is to go on the stage in a theatre.
Stage schools often act as agencies（代理机构）to supply children for stage and television work. More worthy of the name “stage school” are those few places where children attend full time, with a training for the theatre and a general education.
A visit to such schools will leave you in no doubt that the children enjoy themselves. After all, what lively children wouldn’t settle for spending only half the day doing ordinary school work, and acting, singing or dancing their way through the other half of the day?
Then of course there are times for the children to make a name and make a little money in some big shows. Some stage schools give their children too much professional work at such a young age. But the law is very tight on the amount they can do. Those under 13 are limited to 40 days in the year; those over 13 to 80 days.
The schools themselves admit that not all children will be successful in the profession for which they are being trained. So what happens to those who don’t make it? While all the leading schools say they place great importance on children getting good study results, the facts seem to suggest this is not always the case.
People would stop feeling uneasy when realizing that the children they’re talking to________.
A. attend a stage school B. are going to the theatre
C. have got some work to do D. love singing and dancing
In the writer’s opinion, a good stage school should ________.
A. produce star performers
B. help pupils improve their study skills
C. train pupils in language and performing arts
D. provide a general education and stage training.
“Professional work” as used in the text means ________.
A. ordinary school work B. money-making performances
C. stage training at school D. acting, singing or dancing after class
Which of the following best describes how the writer feels about stage schools?
A. He thinks highly of what they have to offer.
B. He favours an early start in the training of performing arts.
C. He feels uncomfortable about children putting on night shows.
D. He doubts the standard of ordinary education they have reached.

A girl named Jenny once told me about her 36 in the world of Lose Win during her eighth grade year before she finally broke 37 :
My 38 with my mom all started one day 39 she said to me sarcastically(讽刺地)，“Wow, you’re sure sassy today.” I 40 it so literally (字面地) that then and there I decided to close myself off from her and never 41 back to her. So every time she would say something 42 I disagreed with her I would just say, “Okay, 43 you want, Mom”
But I really got cold quickly. And my 44 began to build. One night I talked to my mom about the school homework and she said, “Oh, that’s 45 ”and then went back to mop the floor.
“Don’t you ever 46 ?”I thought. But I didn’t say anything and stormed off. She had no idea I was 47 upset. She would have been willing to talk to me had I 48 her how important it was to me.
At last, I just blew up. “Mom, this has got to 49 . You tell me everything you want me to do and I just do it because it’s 50 than fighting. Well, I’m sick of it.” This all came as a 51 to her.
After my blowup, we felt like we were 52 all over in our relationship. But it’s getting better all the time. We discuss things now and I always 53 my feeling with her.
If you adopt Lose Win as your basic 54 toward life, then people will wipe their dirty feet on you. You’ll also be 55 your true feelings deep inside. And that’s not healthy.
