Brenda Bongos was a happy, artistic girl. She had one big ambition—to play the drums in a band. But one big obstacle lay in her way. To be good enough to play in a band, Brenda had to practice a lot, but she lived next-door to a lot of old people. Many of them are sick. She knew that the sound of beating drums would really get on their nerves. So, she had tried playing in the strangest places: a basement, a kitchen, and even in a shower. But there was always someone it would annoy.

    One day, while watching a science documentary on TV, she heard that sound cannot travel in space, because there's no air. At that moment, Brenda Bongos decided to become a sort of musical astronaut.

    With the help of a lot of time, books and work, Brenda built a space bubble. This was a big glass ball connected to a machine which sucked out all the air inside. All that would be left inside was a drum kit(成套设备) and a chair. Brenda got into the space suit she had made, entered the bubble, turned on the machine, and played those drums like a wild child.

    It wasn't long before Brenda Bongos came very famous. Many people came to see her play in her space bubble. Shortly afterwards she came out of the bubble and started giving concerts. Her fame spread so much that the government suggested that she be part of a unique space journey. Finally, Brenda was a real musical astronaut, and had gone far beyond her first ambition of playing drums in a band.

    Years later, when asked how she had achieved all this, she thought for a moment, and said: ''If those old people next – door hadn't mattered so much to me, I wouldn't have found a solution, and none of this would have ever happened.''

61. Why did Brenda try to play in the strangest places?

   A. Because she didn't want others to hear her play.

   B. Because she didn't mean to disturb others.

   C. Because she didn't have her own room.

   D. Because she didn’t like her neighbors.

62. Brenda started to give concerts _______.

   A. after she practiced in her space bubble

   B. when she became part of the unique space journey

   C. after she became a real musicalastronaut

   D. when people came to see her in the space bubble

63. Brenda became famous because _______.

   A. she was good at music and science

   B. she became a real musical astronaut

   C. she invented a special way of practice

   D. she played well and had a talent

64. Which of the following can be used to describe Brenda?

   A. Kind, hardworking andclever.

   B. Brave, kind and hardworking.

   C. Lovely, brave and kind.

   D. Nervous, kind and clever.

   C. Two heads are better than one

   D. One good turn deserves another

Baby girls make their way directly for dolls as soon as they can crawl, while boys will head for the toy cars, a study has shown. The findings, the first to show differences in very young babies, suggest there is a biological(生物学的) basis to their preferences(偏爱).

Psychologists Dr. Brenda Todd from City University London carried out an experiment involving 90 infants(婴儿) aged nine months to 36 months. The babies were allowed to choose from seven toys. Some were stereotypically boys' toys - a car, a digger, a ball and a blue teddy.  The rest were girls’ toys: a pink teddy, a doll and a cooking set. They were placed a meter away from the toys, and could pick whichever toy they liked. Their choice and the amount of time they spent playing with each toy were recorded.

Of the youngest children (nine to 14 months), girls spent significantly longer playing with the doll than boys, and boys spent much more time with the car and ball than the girls did. Among the two-and three-year-olds, girls spent 50 percent of the time playing with the doll while only two boys briefly touched it. The boys spent almost 90 percent of their time playing with cars, which the girls barely touched. There was no link between the parents’ view on which toys were more appropriate for boys or girls, and the children’s choice.

Dr Brenda Todd said: “Children of this age are already exposed to much socialization(社会化). Boys may be given ‘toys that go’ while girls get toys they can care for, which may help shape their preference. But these findings agree with the former idea that children show natural interests in particular kinds of toys. There could be a biological basis for their choices. Males through evolution have been adapted to prefer moving objects, probably through hunting instincts(本能), while girls prefer warmer colours such as pink, the colour of a newborn baby.”

1.Baby boys and girls have different toy preferences probably because__________.    

A.baby boys are much more active

B.baby girls like bright colours more

C.there is a natural difference between them

D.their parents treat them differently

2.What can we infer from Paragraph 3?

A.Nine-month-old baby boys don’t play with dolls at all.

B.Two-year-old baby girls sometimes play with cars and balls.

C.Parents should teach their babies to share each other’s toys.

D.The older the babies are, the more obvious their preference is.

3.What conclusion did Dr. Brenda Todd draw from the results of the study?

A.Babies’ preference isn’t affected by social surroundings.

B.Adults purposely(故意地) influence their babies preference.

C.Baby boys preferring to moving toys will be good at hunting.

D.Baby girls preferring warmer colors will be warm-hearted.

     Have you seen Jurassic Park? In this film, scientists use DNA kept for tens of millions of years to clone dinosaurs. They find trouble, however, when they realize that the cloned creatures are smarter and more dangerous than expected. That’s nothing more than a fiction.

     But could we really clone endangered animals?

     To date, the most successful attempt to do so was the cloning of a gaur, a rare ox-like animal from southeast Asia. Scientists used a cow to bring the cloned baby gaur, named Noah. Two days after birth, however, Noah died from a common bacterial infection. Other endangered species that may be cloned include the African bongo antelope (邦戈羚羊), the Sumatran tiger, the cheetah (猎豹), and the giant panda.     Next, could we really clone extinct animals?

     In theory? Yes. To do this, you need a well-kept source of DNA from the extinct animals such as wool mammoth (毛象), Tasmanian tiger, or even dinosaur, and a closely related species, still living, which could serve as a surrogate mother.

     In reality? Probably not. On the one hand, it’s not likely that extinct animals’ DNA could survive undamaged for such a long time. Cloning extinct animals as wool mammoth, Tasmanian tiger, or dinosaur is much more difficult due to the lack of properly well-preserved DNA. On the other hand, for example, a gaur can have a cow as a surrogate mother, definitely not a monkey. But what about an extinct animals as unique as the panda? What species could possibly serve as a surrogate mother?

     Cloning presents many exciting possibilities. However, even if extinct animals are brought back, they could not survive in today’s world. Not only do most extinct animals have no habitat to love in, but the other plants and animals they depended on for food may also be gone as well.

1. It can be learned from the text that ________.

A. scientists have cloned the African bongo antelope

B. both the cheetah and the giant panda live in Asia

C. the gaur lives in Asia and is endangered 

D. the gaur is an extinct species

2. The underlined words “a surrogate mother” probably refer to a female who -----

A. contributes its eggs to another female   B. gives birth to a baby for another female

C. gives birth to a baby of its own        D. cannot give birth to a baby

3. The difficulty in cloning an extinct species is the lack of ______.

  A. both the well-preserved DNA and plants to live on

  B. both the habitat to live in and the well-preserved DNA

  C. both habitat to live in and plants to live on

  D. both the well-preserved DNA and a surrogate mother

4. In the author’s opinion, it is possible that ______.

  A. some extinct species may be cloned, but not survive

  B. extinct species may be cloned and easily survive

  C. a gaur can have a monkey as a surrogate mother

  D. all the extinct species may be cloned

5.Today , have scientists  cloned  dinosaus?
