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.Which of the following is TRUE according to Paragraph 1?

What are you going to do if you are in a burning house? How will you escape? Do you know how to save yourself? Please read the following passage.
Escaping from a fire is a serious matter. Knowing what to do during a fire can save your life. It’s important to know the ways you can use and show them to everyone in the family, such as stairways and fire escapes, but not elevators.
From the lower floors of the buildings, escaping through windows is possible. Learn the best way of leaving by windows with the least chance of serious injury.
The second floor window is usually not very high from the ground. Of course, it is safer to jump a short way than to stay in a burning building.
Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or smoke and fire may come into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may get into the room.
On a second or third floor, the best windows for escape are those that open onto a roof . From the roof a person can drop to the ground more safely. Dropping onto hard ground might end in injury. Bushes and grass can help to break a fall.
根据短文内容,判断句子正(T)误(F)。It’s serious to know how to escape from a fire.
In a fire we can use elevators to come down.
Windows can’t be used when you are waiting for help.
Doors must all be open so that smoke can come into the room.

What do people do with their old, out of date but still useful computers? Most people don’t know how to do with them. Many old computers are put away. Many more are simply thrown away as rubbish
Finally, some companies are thinking of ways to bring down the number of old computers.Sony has agreed to help recycle old Sony products(产品).Dell,Hewlett-Packard and other companies now also take back some old computers of their own brands.
In some countries, laws are being passed, too. Computer companies have to play for collecting and recycling their used products. And 70% of computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay for the cost. That will encourage them to make computers which are easier and cheaper to repair and upgrade(升级).
Yet many people are throwing away good computers, while others cannot afford them at all. Hundreds of organizations are working to solve this problem. They collect and repair old computers. Some also teach others how to repair computers. These repaired computers then go to schools, charities (慈善团体)or people who need them. Giving a used computer to one of these organizations can turn one person’s rubbish into someone else’s useful things and cut down on waste, too.

A kind of little cars may take the place of today’s big ones many years later. If everyone drives such cars in the future, there will be less pollution in the air. There will also be more space for parking in cities, and the streets will be less crowded.
The little cars of the future will cost less. Driving will be safer, too, since these little cars can go only 65 kilometers an hour. The cars of the future will be fine for going around a city, but they will not be useful for a long way. Little cars will go 450 kilometers before they need to stop for more gasoline (汽油). If big cars are still used with the small ones, two kinds of roads will be needed in the future. Some roads will be needed for the big, faster cars and other roads will be needed for the small, slower ones.

During a winter storm in 1919, one dog managed to save the lives of the people on the ship Ethie. Today, people still tell the story of the dog.
In December 1919, Ethie was travelling along the coast of northern Canada. Without warning, the ship ran into a bad storm. Because of high winds and heavy snow, the captain could not tell where he was going. Sailing too close to the shore (岸), the ship could not move because of some rocks. Ethie was in danger.
The captain decided to save the people on his ship. He thought it was too dangerous to try to reach the shore by lifeboat, so he sent up flares (闪光信号) to call for help. People saw the flares and rushed to the beach. The crew (船员) tried to throw a rope (绳子) to them, but there seemed to be no way to get a rope to the shore.
In the early 1900s ships often carried a large kind of dog called a Newfoundland. Newfoundlands are excellent swimmers. During sea journeys, Newfoundlands would bring back things that had fallen off the ship or even save people from the sea.
The Newfoundland on Ethie was named Tang. The captain decided that Tang offered their best hope of survival (幸存). He gave the dog a long rope. Holding the rope between his teeth, Tang jumped into the turbulent water. He fought his way through high waves and strong winds. Finally he reached the beach.
The people on the shore took the rope. The rope became the ship’s lifeline.
Because of Tang, all the people on Ethie landed on the beach safely. He was given a special medal for being a hero. Tang wore the medal for the rest of his life.What happened to the ship Ethie at the beginning of the story?
