Should we be afraid of sharks? Maybe not. New research into the reasons for shark attacks (攻击) suggests that sharks don’t like the way humans taste! In fact, most people who are attacked by the shark are still alive after receiving only one bite (咬). Why is this?

There are many opinions to explain why sharks sometimes attack people. One opinion is that sharks are just curious (好奇的). We know that sharks are the strongest animals in their environment, so they are not afraid of anything. Naturally, that means they are curious when they meet something unusual. Because they don’t have hands or feet., the only way they can find out an object is to bite it! It is thought that sharks sometimes bite humans for this reason, and then swim away.

Scientists also say that sharks would not waste energy trying to eat a human, as we have a lot of bones (骨头). It is hard for a shark to eat us because sharks don’t have hands, and they can’t pull the meat off our bones. Maybe that’s why they only bite us once. Unluckily, one bite from a large shark is serious enough to hurt people greatly!

Another opinion is that sharks attack humans by mistake. Some sharks may sometimes mistake humans for a seal. An example of this is when a shark attack attacks a surfer. A surfer lying on a surfboard looks like a seal when seen from below. Sharks like seals because they have thick fat.

Whatever the reason for shark attacks on humans, sharks should be afraid of us. Sadly, we kill almost 40 million of them each year.

Everyone needs friends. We all like to   1  close to someone.   2  is nice to have a friend to talk, laugh, and do things with. Certainly, sometimes we need to be alone. We don't always want people   3 . But we will feel lonely if we  4  have a friend.

No two people are just the same. Friends   5  don't get on(相处的) well. That doesn't mean that they no longer like each other. As time passes, they will make up(言归于好) and become   6  again.

Sometimes friends move away. Then we feel very   7 . We miss them very much, but we can   8  them and write to them. It is likely that we would never see them again. And we can   9  new friends.

There's more good news for people who have friends. They live longer than people who don't. Why? It could be true that they are  10 . Being happy helps you keep healthy.

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.
