A Southampton University team found that people who were vegetarians by 30 had recorded five IQ points higher on average at the age of 10. Researchers said it could explain why people with a higher IQ were healthier as a vegetarian diet was linked to lower heart disease and obesity rates. The study of 8，179 people was reported in the British Medical Journal.
Twenty years after the IQ tests were carried out in 1970，366 of the participants said they were vegetarians — although more than 100 reported eating either fish or chicken.
Men who were vegetarians had an IQ score of106，compared with 101 for non-vegetarians； while female vegetarians averaged 104, compared with 99for non-vegetarians. There was no difference in the IQ scores between strict vegetarians and those who said they were vegetarians but reported eating fish or chicken.
Researchers said the findings were partly related to better education and higher class, but it remained statistically significant after adjusting for these factors.
Vegetarians were more likely to be female, to be of higher social class and to have higher academic or vocational qualifications than non-vegetarians. How-ever, these differences were not reflected in their annual income, which was similar to that of non-vegetarians.
Lead researcher Catharine Gale said，"The findings that children with greater intelligence are more likely to report being vegetarians as adults, together with the evidence on the potential benefits of a vegetarian diet on heart health, may help to explain why a higher IQ in childhood or adolescence is linked with a reduced risk of coronary heart disease in adult life. ”
But Dr. Frankie Phillips of the British Dietetic Association said，“ It is like the chicken and the egg . Do people become vegetarians because they have a very high IQ or is it just that they are clever enough to be more aware of health issues?" What's the result of the research mentioned in the text?
| A．Intelligent children are more likely to become vegetarians later in life. |
| B．Children with a higher IQ are less likely to have heart disease later in life. |
| C．Intelligent children tend to belong to higher social class later in life. |
| D．Children with a healthier heart tend to have a higher IQ later in life. |

| A．most of the participants became vegetarians 20years after the IQ tests were carried out |
| B．vegetarians who ate fish or chicken were of similar intelligence with strict vegetarians |
| C．female vegetarians were more likely to have higher annual income than non-vegetarians |
| D．vegetarians were more likely to have higher annual income than non-vegetarians |
What does the underlined sentence in the last paragraph mean?
| A．Intelligence is linked to not just being a vegetarian but to many factors. |
| B．The rate of getting heart disease is linked to your lifestyle. |
| C．The link between a high IQ and being a vegetarian is still uncertain. |

| B．Be a vegetarian, please! |
| C．Vegetarian diet cuts heart risk. |
| D．A high IQ is linked to being a vegetarian. |
No one knows why we sleep, but it’s certain that we need to. People who are prevented from sleeping begin to suffer obvious effects after a few days—they think less clearly, and they fall asleep during the working hours; some may have hallucinations(幻觉).
There are no rules about sleep. Generally speaking, grown-ups sleep about 7 and a half hours each night and probably more than 60 per cent get between seven and eight hours. But perhaps eight per cent are quite happy with 5 hours or less, and four per cent or so find that they want ten hours or more. If you feel all right, you’re probably getting enough sleep. The important thing is not to worry how much other people get—their needs may be different. Exercise doesn’t seem to increase the need for sleep—office workers, for example, sleep for about as long as people doing physically active work.
Children sleep more than grown-ups—perhaps 14 to 18 hours soon after birth, going down to grown-up levels by early teenage. Sleep patterns also tend(倾向) to be different in the elderly, who may sleep less at night than they did when younger, find sleep getting more broken, and often make it a rule to sleep during the daytime.According to the passage, some people are unable to think clearly because ___________ .
| A．they have hallucinations |
| B．they feel sleepy during the working hours |
| C．they don’t have enough sleep |
| D．they are certain to be kept from going to bed |
Which of the following is TRUE?
| A．All grown-ups must have at least eight-hour sleep. |
| B．Most of grown-ups sleep for seven or eight hours. |
| C．Quite a few people need only 5 hours or less for them to sleep. |
| D．No grown-ups sleep more than ten hours. |
Whether you have got enough sleep is judged by__________.
| A．how many hours you have slept |
| B．how many hours you need to sleep |
| C．whether you do exercise and physical work |
| D．whether you feel fresh and energetic |

An English saying goes: “All work and no play makes Jack a dull boy.” That means we should relax after a day’s hard work or we’ll be unhealthy.
Many students know that if they want to get ideal jobs with good salaries, they must do well in high school so they can enter good universities. Therefore, they spend all day studying without time to relax.
However, not all students can go to top universities even if they work very hard. Students are pressurized by parents and teachers who are just concerned about their studies and exam scores while ignoring their hobbies and individual differences. As a result, students are forces to work harder and harder. Furthermore, there is pressure coming from students themselves. They realize they have a slim chance of getting into a top university as competition is fierce. So, they put a lot of stress on themselves and stay in a nervous state day after day. If they keep it up, they’ll suffer illnesses; both psychological and physical.
What students need is relaxation. This doesn’t mean that they should give up their ambitions and stop studying hard. It means “work while you work, play while you play”. If you can do this, you will improve your health greatly. You’ll feel yourself suddenly fresh, just like recovering from a terrible illness. You’ll find that your studies are not a burden(负担) anymore.The underlined part in the first paragraph might mean all the following EXCEPT______.
| A．too much work may bring trouble to anyone |
| B．overwork without rest is sure to make one foolish |
| C．Jack becomes dull because he works too much |
| D．Anyone who doesn’t work will break down |
What trouble have both the parents and teachers brought to the students?
| A．They don’t know how to let the students relax. |
| B．They give too much burden for them to bear. |
| C．They don’t love those who work the hardest. |
| D．They fail to understand what the students need most. |
What causes the student’ pressure from themselves?
| A．That they don’t know how to get top universities. |
| B．That they want to relax but have no chance. |
| C．That they fail to relax themselves during their work. |
| D．That they think too much about the result of their work. |
What is the passage mainly about?
| A．What to do to relax yourself. |
| B．The serous situation for the poor students. |
| C．Some problems caused by the misunderstanding of learning. |
| D．How to be a healthy and successful learner. |
There are many differences between America and China. The biggest difference is traffic rules. In America there are too much more cars than in China. But there are much fewer traffic jams and accidents in America than in China. We hardly see traffic police in the street, but all cars obey strictly traffic rules, and people hardly find that a car does not obey traffic rules in the street.
About American traffic rules, there are many better terms, such as:
1. Stop line: There are stop lines in all crossing without traffic light (some have two stop lines and others have four stop lines). All cars must stop while meeting the stop line.
2. Traffic light: There is traffic light in the crossing of the road. Cars may almost turn every direction. The traffic light can give signal step by step including u-turn. There is a kind of middle lane of turning left. When a car wants to turn left in the road, he may enter into the middle lane of turning left and give a signal of turning left. When he thinks being safe, he may turn left. In many conditions the order of passing is also given very specifically. If people want to change lane or turn, they must look behind and think being safe. Only so, they may do it.
3. Specific item: Such as parking, there are three kinds of lines (their colors are white, blue or red) in the roadside. Every line may park different kinds of cars. There are many streets in some residential areas (住宅区), and there is a kind of rule that any car cannot park at any time or any period time. In every parking, there are some special positions for invalid (伤残的) people.
4. About the priority of passenger and car: At any case, passengers have the priority to cars. And only after passengers have passed the road and got the top of sidestep, cars may go ahead.

| A．Traffic police are not very necessary because few cars break traffic rules. |
| B．The traffic is very clear and there are few traffic jams and accidents in the street. |
| C．There are so many cars in the street that the traffic police can’t be seen. |
| D．The effective traffic rules play an important part in the road safety. |
Why is there a middle lane of turning left on the road?
| A．It is designed for the cars that want to turn left. |
| B．It is very safe to drive there. |
| C．It is very convenient for the traffic police to find the cars that break the rules. |
| D．The cars that want to turn left can easily give a signal of turning left. |

More than four out of five people admit to telling little white lies at least once a day and the preferred way of “being economical with the truth” is to use technology such as cellphones, text messages and e-mails, a survey said last Thursday. The research found that “techno-treachery （高科技说谎）” was widespread with nearly 75 percent of people saying gadgets (小器具) made it easier to fib (撒小谎). Just over half of the respondents （被调查者） said using gadgets made them feel less guilty when telling a lie than doing it face to face. The workplace was a favorite location for fibbing with 67 percent of the 1,487 respondents admitting they had lied at work. The top lie was pretending to be ill (43 percent), followed by saying work had been completed when it hadn’t (23 percent). Worryingly for bosses 18 percent said they lied to hide a big mistake. But, employers were not the only ones on the receiving end of dishonest statements. Just over 40 percent of the respondents said they had lied to their families or partners. Key topics to lie about were: buying new clothes or the cost of them (37 percent), how good someone looked in something (35 percent), how much they had eaten (35 percent) and drunk (31 percent) and how much they weighed (32 percent). The underlined phrase “being economical with the truth” probably means______.
| A．telling lies | B．making apologies | C．feeling guilty | D．admitting mistakes |
