true that a dog is one of the most useful animals in the world, but the reason that one keeps a dog has
changed. Long, long ago, a man met a dog and wanted it to help him fight other animals and he found
that the dog listened to him and did what he told it to. Later people used dogs for hunting for other
animals, and the dog didn"t eat what they got until their master agreed. So dogs were used for driving
sheep and guarding chickens. But now people in the towns and cities do not need dogs to fight other
animals. They keep them to frighten thieves, but the most important reason is that people feel lonely in
the city. For a child, a dog is the best friend when he has no friends to play with. For a young wife, a
dog is her child when she doesn"t have her own. For old people, a dog is also a child when their real
children have grown up and left. Now people do not have to use a dog, but they keep it as a friend,
just like a member of the family.

( )2. Short people often have better balance than tall people.
( )3. If you want to run fast, you must have long legs.
( )4. There is a lot of medicine to make people grow taller.
( )5. Some young people grow taller than their parents because they eat better.
People usually think that boys are stronger, heavier and taller than girls. Maybe it"s true. Some people even think that boys are smarter than girls. Expert"s view: I can"t agree with them. If you say that girls learn faster than boys, you may be right, at least when it comes to young chimps(猩猩)using tools. People
found that girl chimps in Tanzania, East Africa, use sticks to find tasty insects(昆虫)two years earlier
than boy chimps. This is because young girl chimps watch their moms collect bugs, while the boy chimps climbtrees.But young boy chimps may hunt and throw(扔)sooner than girl chimps.It"s also true for humans. It"s easier for girls to learn to write and draw earlier, but boys often run and throw balls earlier than girls.
Teacher"s view: I think boys and girls both have their special advantages. Boys are good at sports. They are very athletic. But girls do well in performance. They are very calm.

highest mountains; some traveled into unknown parts of the world; some sailed small boats across the
largest sea. Now some people begin to look for new excitement.
Bungee jumping (蹦极) and motorcycle racing (摩托车赛) are quite dangerous sports. Bungee
jumping only lasts a few minutes or even seconds. You jump from a high place, 200 meters above the
ground, and there is a rubber band (橡胶带子) tied to your legs. When you jump down, the rubber
band pulls you up. About 2,000,000 people around the world have tried bungee jumping.
Why do people join in these dangerous sports? Some scientists say that it is because modern life
has become safe and it is not interesting. In the past, people lived in danger. They had to go out and
look for food, and life was like a fight but was interesting.

in shops, and there are doctors and hospitals to look after them if they become ill.
