People and dogs have been living together for thousands of years. When did dogs and people become friends Where did dogs come from
A group of scientists tried to answer these questions. They just finished a study about the history of dogs. In the study, they looked at the DNA of dogs all over the world and found that dogs, like humans, shared DNA with their family members. The scientists put together a big family tree for dogs. It went all the way back to the animal’s beginning.
In this way, scientists learned about the history of dogs. The first dogs lived in Asia. They were born about 33,000 years ago. At first, there were only about 6,400 of them. Their parents were wolves.
The new study answers many questions. It raises some too. For example, what caused wolves in Asia to become dogs all those years ago
One idea is that their DNA slowly changed and the wolves became dogs in the end. As time went by, dogs became “man’s best friends”. Or it could happen the other way around. It was possible that some wolves started living with people before they became dogs. Living with people led to many changes to these wolves. It changed their DNA, so their offspring(后代) became dogs. In other words, it was possible that the wolves were our friends before they became dogs.
By studying DNA, scientists now have a much better under standing of the history of dogs.

A. By telling a story. B. By giving an example.

B. They were born 6,400 years ago.
C. Their parents were wolves.
D. There were about 33,000 dogs.
( )3. What does the underlined word “some” in Paragraph 4 refer to
A. Wolves. B. Dogs. C. Ideas. D. Questions.
( )4. Which of the following can be put in “ ▲ ”
A. However, there is still much to learn
B. But we still know little about wolves ’ history
C. Because we’ve learned about dogs’ friends
D. So they can explain when dogs became our friends

阅读下面短文，完成短文后的问题。
How much do you know about cheetahs
The cheetah is a truly unique animal as the world’s fastest land animal. A cheetah can go from zero to 60 miles an hour in only three seconds. Most cheetahs live in Africa.
In the past 100 years, the number of cheetahs living in the wild has dropped from 100,000 to fewer than 12,000. They are in danger of dying out because they have few places to live and people hunt them. Can we help cheetahs in danger
Wildlife scientists hope so. They are trying to protect cheetahs by letting people know about their situation and thinking about some useful ways to keep them safe.
Good news for cheetahs at the Saint Louis Zoo! Three baby cheetahs that were born in November are growing up at the Saint Louis Zoo. “The babies do well,” the zoo’s worker, Steve, said. “They are very active and healthy. They like playing with each other or with their mum.”
By raising baby cheetahs, the zoo is working to save cheetahs from dying out. The zoo is also helping protect cheetahs in the wild. “We want children to know that cheetahs are in danger,” said Steve. “It is important to protect their living space.”
1. How long does a cheetah need to r each the speed of 60 miles per hour
