Say sorry to your wife---it may help her live longer, according to scientists.

“Sorry” may be the hardest word, but scientists say it could be one of the healthiest. Researchers have discovered that women who receive an apology for hurtful behavior suffer less stress and possible damage to their heart than those who don’t.

It is said that the heartbeat of a wronged woman returns to normal 20 percent quicker after a well-timed “sorry” than without it. But for men, their heartbeat takes longer to recover, according to the research.

The research was undertaken by American scientists using 29 men and 59  women whose diastolic blood pressure was measured throughout an experiment. Diastolic blood pressure

is a measure of pressure in the blood vessels( 血管 ) between heartbeats---if it is continuously high it can increase the chances of heart attacks.

The men and women were asked to undertake a difficult mathematical task. They were told they had five minutes to complete it but were disturbed after a minute and told rudely to carry out the task more quickly. They were disturbed twice more before five minutes had passed and told to speed up. Finally they were told, “ You’re obviously not good enough.” Two minutes later researchers said sorry to half of the men and women.

The researchers found that, on average, the women’s diastolic blood pressure dropped back to normal 20 percent---quicker if they received an apology from the researchers, while the men’s took 20 percent longer to return to normal. One of the researchers said, “Results indicates that the effects of apology and forgiveness on women are greater.”

1.The term “sorry” is considered as one of the healthiest words because it _________.

2.We can know from Paragraph 3 _________.

3.Which of the following is the RIGHT time order for events in the study?

a. Half of them received apologies.

b. They were disturbed a minute later.

c. They were told that they weren’t good enough.

d. They were asked to finish a math task in five minutes.

e. They were disturbed two more times during the study.

4.The research confirmed (证实) that _________.

Scientists think it will be possible to record people's dreams and then interpret them, according to a new report.

They claim to have developed a system which allows them to record higher level brain activity.

Dr Moran Cerf told the journal Nature: "We would like to read people's dreams."

Previously the only way to access people's dreams is for psychologists to ask about them after the event and try to interpret them.

Dr Cerf hopes to eventually compare people's memories of their dreams with an electronic visualization(影像) of their brain activity.

He told the BBC: "There's no clear answer as to why humans dream. And one of the questions we would like to answer is when do we actually create this dream?"

The scientist believes his latest research shows that certain neurons(神经元) or individual brain cells are linked with specific objects or concepts.

He found that a particular neuron lit up when a volunteer thought about Marilyn Monroe.

If a database was built up identifying various neurons with concepts, objects and people it would allow them to "read the subject's minds", according to Dr Cerf.

However, Dr Roderick Oner, a clinical psychologist and dream expert, said that this kind of visualisation would be of limited help when it came to interpreting the "complex dream narrative".

In addition to get a detailed picture of individual neurons subjects had to have electrodes implanted(植入电极) deep in the brain using surgery.

The Nature researchers used data from patients who had electrodes implanted to monitor and treat them for brain seizures(癫痫).

However, Dr Cerf said he hoped that it would be possible at a later stage to monitor people without invasive surgery. He said it would be "wonderful" to be able to read the minds of coma patients who are unable to communicate.

1.According to the passage, psychologists try to interpret people’s dreams______.

A. by recording higher level brain activity

B. by comparing people’s memories of their dreams with an electronic visualization

C. by asking about people after their dreams

D. by linking certain neurons with specific objects or concept

2.What’s the best title for this passage?

A. Scientists plan to record people’s dreams

B. Psychologists try to ask people about their dreams

C. Dream experts want to interpret the complex dream narrative

D. The Nature researchers intend to treat patients for brain seizures

3.According to Dr Cerf’s research, when a patient thinks about a famous film star, ______.

A. various neurons will identify the star as famous

B. a particular neuron will become bright with excitement

C. the star will appear in his brain

D. the star’s face will light up

4.The underlined word “coma” in the last paragraph most probably means______.

A. the lost of the ability to hear

B. being unable to control one’s movements

C. the state of being unconscious (无意识的)

D. being unable to move

A new study has found that it may be possible to train people to be more intelligent, increasing the brainpower they had at birth．

Until now，it has been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience—what psychologists call fluid intelligence—is innate and cannot be taught（though people can raise their grades on tests of it by practicing）．

But in the new study，researchers describe a method for improving this skill，along with experiments to prove it works．

The key, researchers found, was carefully structured training in working memory—the kind that allows memorization of a telephone number just long enough to dial it．This type of memory is closely related to fluid intelligence，so the researchers reasoned that improving it might lead to improvements in fluid intelligence．

First they measured fluid intelligence of volunteers using standard tests．Then they trained each in a complicated memory task—the child’s card game，in which they had to recall a card they saw and heard．During the course, they needed to ignore irrelevant items, monitor ongoing performance，manage two tasks at the same time and connect related items to one another in space and time．

The four groups experienced a half-hour of training daily for 8, 12, 17 and 19 days, respectively．To make sure they were not just improving their test-taking skills，the researchers compared them with control groups that took the tests without the training．

The results, published Monday in The Proceedings of the National Academy of Sciences，were striking．Improvement in the trained groups was a lot greater．Moreover，the longer they trained, the higher their scores were．All performers，from the weakest to the strongest，showed significant improvement．

“Our results show you can increase your intelligence with proper training．” said Dr Jaeggi, a co-author of the paper．“No one knows how long the gains will last after training stops,” he added, “and the experiment’s design did not allow the researchers to determine whether more training would continue to produce further gains．

1.By writing the article，the writer intends to ______________．

A. inform the readers of a new study

B. call on people to be trained to increase intelligence

C. prove one’s born brainpower can be improved

D. tell people the improved intelligence will last forever

2.The researchers thought the key to improving the intelligence was ______________．

A. memorizing telephone numbers　　　

B .improving working memory

C. training in concentration　　　　　　　

D. recalling a card

3.The following aspects of the training help increase intelligence EXCEPT___________．

A. ignoring irrelevant items　　　　　　　　

B.monitoring ongoing performance

C.managing two tasks at the same time　　

D.using previous experience

4.When the experiment was conducted, the researchers______________．

A.trained the four groups for the same period of time

B.only made comparisons between the four groups

C.compared the four groups with control groups

D.trained the four groups together

Advice to “sleep on it” could be well founded, scientists say. After a good night’s sleep, a problem, which couldn’t be solved the night before, can often seem more manageable, although the evidence until now has been anecdotal (个人体验的). But researchers, at the University of Luebek in Germany, have designed an experiment that shows a good night’s sleep can improve insight (顿悟) and problem-solving.

“If you have some newly-got memories in your brain, sleep acts on these memories and restructures (重新组织) them, and as a result, after sleep, the insight into problem which you could not solve before increases,” said Dr Jan Born, a neuroscientist (神经科学家), at the university.

To test the theory, they taught volunteers two simple rules to help them turn a string of (一连串) numbers into a new order. There was also a third, hidden rule, which could help them increase their speed in solving the problem. The researchers divided the volunteers into two groups: Half were allowed to sleep after the training, while the rest were forced to stay awake. Dr Jan Born and his team noticed that the group that had slept after the training were twice as likely to figure out (想出) the third rule as the other group.

“Sleep helped,” Born said in a telephone interview. “The important thing is that you have to have a memory representation (描绘，表现) of the problem you want to solve in your brain and then you sleep, so it can act on the problem.” But Born admitted that he and his team don’t know how restructuring of memories occurs or what governs it.

Pierre Maquet and Perrine Ruby of the University of Liege in Belgium said the experimental evidence supports the anecdotal suggestions that sleep can help develop creative thinking. Although the role of sleep in human creativity will still be a mystery, the research gives people good reason to fully respect their periods of sleep, they added.

1.The underlined phrase “sleep on it” in Paragraph 1 probably means ______.

A. to delay deciding something until the next day

B. to get as much sleep as possible

C. to go on sleeping without being disturbed

D. to sleep till after the time you usually get up in the morning

2.Jan Born and his team carried out the experiment through ______.

A. comparison       B. interview         C. survey       D. imagination

3.It can be inferred from the passage that ______.

A. people should sleep so long as they have time

B. sleep is the only way to solve hard problems

C. people have various periods of sleep

D. people know how sleep reconstructs memories

4.What would be the best title for the passage?

A. How Sleep Works                       B. Sleep Helps Solve Problems

C. No Evidence, But Well Founded         D. Born’s Discovery On Sleep

Even if you really enjoy your job, it’s still possible to feel bored as you work. You may not be able to make big changes—or change your job—but you can make small adjustments. Here are some tips on how to battle boredom.

1. Switch Your Seat

Change your outlook at the office by changing your office. Ask your assistant to help you find a new desk. If it’s not possible to change your location, see if you can change your desk’s direction. A new view can be just as refreshing as a new location.

2. ______________

Take a subway. Ride a bike on sunny days. You needn’t change the way to go to work for ever—just long enough to help you escape the boredom.

3. Find a New Work Style

Tired of attending that long-standing Monday morning meeting? Try to change it to the afternoon. If you find yourself feeling most bored in the afternoons, try to arrange to do your favorite tasks then and tackle less desirable projects in the mornings. If you usually communicate with coworkers via email and instant messaging, start dealing with people face to face. Increased communication with coworkers may help improve your mood.

4. Get and Set an aim

If your work is short of aims, it’s no wonder that work has become boring. Set an aim. Your aim needn’t be great as long as you are enthusiastic about it. Whatever it is, actively move toward an objective.

1. What is the main idea of the passage? (within 10 words)

______________________________________________________________________________________

2.Which sentence in the text is the closest in meaning to the following one?

You will feel bored when you are not working toward something.

______________________________________________________________________________________

3. Fill in the blank in Paragraph 3 with proper words. (within 8 words)

———————————————————————————————————————————

4. List three methods of escaping from boredom from the passage. (within 5 words for each)

①________________________  ②________________________  ③________________________

5.Translate the underlined sentence in the Last Paragraph into Chinese.
