Do you know that women’s brains are smaller than men’s? Normally the women’s brain weighs 10% less than men’s. Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent(聪明的) than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain. The brain is made up of “grey matter” and “white matter”. While men have more of the white matter, the amount(数量)of “thinking” brain is almost the same in both men and women.
It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls may learn to speak earlier, and that women can understand sorts of different information at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.
There are other important differences between two sexes(性别). As white matter is the key to spatial(空间的)tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life’s great mysteries: why men refuse to ask for directions … and women often need to!
The differences begin when fetuses(胎儿)are about nine weeks old, which can be seen in the action of children when they are very young. A boy would try to climb a barrier before him or push it down while a girl would ask for help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.

A.Grey matter controls thinking in the brain.
B.Men’s brain is 10% less than women’s.

A.Men have weaker spatial abilities.
B.Women do not need to tell directions.
C.Women prefer doing many things at a time.
D.Women do many jobs at a time better than men.

答案

小题1:A
小题1:D
小题1:D
小题1:C
解析

小题1:A 推理判断。由第一段最后两句可知。尽管男人有更多的后者(白质),但是大脑的思考部分(当然是灰质)的量男女几乎完全相等。A有很大的迷惑性,但仔细一看文章中说的是平均。
小题1:D 推理判断。可采用排除法。女人在同时完成多项任务上有优势,并不是说女人喜欢同时干许多事情,因此A 错。C 、D明显与文章内容不符。
小题1:D 推理判断。由more men take up jobs that require good spatial skills, while more women speech skills(while more women take up jobs that require speech skills.)一句可知。
小题1:C . 考查文章大意。本文主要讲述科学家对男女两性大脑的研究,故选C。

Phys ed (physical education) is making a comeback, but with a difference. The new way is to teach skills that are useful beyond gym class, like lifting weights, balancing their diets and building physical endurance(耐力).
Considering that 15% of American children 6 to 18 are overweight, supporters say more money and thought must be put into phys ed curriculum. In many cases, that may mean not just replacing the old gym-class model with fitness programs but also starting up phys ed programs because school boards(教育委员会)often “cut P.E. completely or decrease(减少)its teachers or the days it is offered,” says Alicia Moag-Stahlberg, the director of Action for Health Kids. The difference in phys ed programs is its short of a national standard.
The wisdom of the new idea has some scientific support. Researchers at the University of Wisconsin have showed how successful the fit-for-life model of gym class can be. They observed how 50 overweight children lost more weight when they cycled and skied cross-country than when they played sports. The researchers have also found that teaching group sports like football results in less overall(全体的)movement, partly because the students who are unwilling to do may sit on the bench.
Another problem with simply teaching group sports in gym class is that only a small part of students continue playing them after finishing their high school. The new method teaches skills that translate to adulthood, which means kids are given skills and experiences so they can lead a physically active life in their future.
小题1:Is the new Phys ed program different from the one before?
小题2:What does the new P.E. program teach the students?
小题3:According to the passage, what do some school boards do with P.E?
小题4:What are the problems with simply teaching group sports?
小题5:What’s the passage mainly about?

Recently, more and more people pay attention to eating healthily. Some food additives(添加剂) are used to make different kinds of foods. Some of them can make the food more delicious and some of them can make it colorful. But lots of chemicals are used to produce what we eat every day.
Sudan red is a kind of chemical that factories used it to dye cloth, make the shoes brighter. But some people produced salted duck eggs with it . However, it isn’t a kind of food additive. The food made from Sudan red makes it easier to cause cancer. Melamine(三聚氰胺) is another kind of chemical that are banned(禁止). It’s white crystal(晶体), which was discovered by a German chemist called Sustus Von Liebig in 1834. Melamine can be used to make paper, medicine and woods, ect. But nobody can imagine that some people used it as a material of milk powder(粉末). Because of melamine, it’s reported that 4 babies died and more than 50 thousand babies are affected since 2008. Sanlu, a famous milk powder factory was closed. Whats worse, milk powder with melamine appeared in 2011 again. Problems of food safety, for example, poisonous rice, lean meat powder(瘦肉精) and plasticizers(塑化剂) are becoming more and more serious.
Fortunately, lots of laws have been made to make the solution(解决方法) better. We think we will eat more healthily in the future.
小题1:Can the food additives make the food colorful and more delicious?
小题2:What is Sudan red?
小题3: When was melamine discovered?
小题4:请将划线句子翻译成汉语。
小题5:为了保证食品安全,避免类似事件发生,请你用英语给负责食品安全的相关部门提出建议(只需一条即可)。

Today there are 6.4 billion people on the earth. By the year 2050 there may be 12.5 billion . There are a lot of people to feed. We need more  and more food.
One way to produce more food is growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic(遗传的) material. Foods from plants grown in this way are called genetically modified(改变的) foods, or GM foods.
By changing the genetic material of a plant, it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases; a kind of rice is being prepared , for example , which stops people becoming blind.
Rich countries produce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food.
GM plants are not natural. No one knows how good or bad they are,. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them, because they are unnatural. They may feed people , then hurt them or their children later. But both rich and poor countries are interested in their use, and they are not going to go away.
