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.

China's first moon rover (月球车), Yutu, set off from the lander(登陆车) early on December 15, several hours after the Chang'e-3 probe (探测器) soft-landed on the moon surface.

The 140 kg six-wheeled rover touched the moon surface at 4:35 a.m., leaving deep lines on the loose moon land. This was recorded by the camera on the lander and the images were sent to the earth, according to the Beijing Aerospace Control Center. After that, the rover and lander will take photos of each other and start their own science explorations.

Earlier this morning, engineers made final checks of the environment of the landing area and the situation of the probe(探测仪). Yutu, reached its solar panel (光板) and started to drive slowly to the moon at 3:10 a.m.. It took Yutu nearly a whole hour to complete the simple task.

Chang'e-3 landed at the Bay of Rainbows on the moon, at 9:11 p.m. on December 14, making China the third country in the world to carry out such a mission (执行此类任务) after the United States and Russia.

In old Chinese tales, Yutu was the white pet rabbit of Chang'e’s. The name for the rover was selected following an online survey that collected several million votes from people around the world.

The rover, 1.5 meters long with its two wings folded (折叠), 1 m in width and 1.1 m in height, is a perfect robot controlled by the command center from the earth. It will face challenges including temperature differences of more than 300℃ on the moon.

Yutu will do some research and look for natural resources (资源) for three months, while the lander will conduct an exploration at the landing place for one year. Then they will have a good rest on the moon and will not be used for a long time until China’s next probe visits the moon again.

Now I know that we black people are much more likely to have high blood pressure and diabetes (糖尿病) than white people. And they often lead to heart attacks and other untreated diseases. For example, black people are three to four times more likely than white people to have high blood pressure and twice as likely as the white population to die of a stroke (中风).

New research has found out the surprisingly high levels of salt in many of black people’s favorite meals. I stopped putting extra salt in my food at the table long ago and I try to cut down on the salt. I use in cooking. The suggested daily level of salt for adults is 6 grams. It is easy to see that if you try not to eat too many processed (加工过的) foods and use salt in your cooking within the limit, you won’t reach more than the daily level.

The research showed how much salt there is in some foods that we buy from restaurants and takeaways. An average salad with rice and peas has 6.2 grams of salt. This is more salt than you are supposed to eat for the whole day.

A researcher talked about the importance of home cooking rather than take-outs. At home, he pointed out, not only can you hold control of the salt bottle, but also you can create tasty food which is low on salt. The researcher later provided curry goat and rice and peas. They were low on salt, but completely delicious.

I do not suppose Jamaicans are going to stop buying takeaways soon. But if you suffer from high blood pressure, it is probably better not to buy them often.

1.The underlined word “they” in Paragraph 1 refers to _______.

A.white people                          B.black people

C.untreated diseases                      D.high blood pressure and diabetes

2.What has the new research found out according to Paragraph 2?

A.Black people take in too much salt.

B.Black people’s meals are very special.

C.Processed foods have too much salt in them.

D.6 grams of salt per day is enough for an adult.

3.What would the writer probably suggest black people do?

A.Order no salad in a restaurant.             B.Take in no salt for several days.

C.Stop cooking their favorite meals.           D.Eat less takeaways.

4.The researcher provided curry goat and rice and peas in order to _______.

A.thank those who came to his home for his research

B.let people know that eating less salt makes one healthier

C.show that tasty food with less salt can be made at home

D.prove the less salt the food has the more delicious it is

5.What would be the best title for this passage?

A.Watch the salt                          B.Take care, black people

C.Say no to takeaways                     D.Say no to high blood pressure
