21、Scientists have long debated how the bird ancestors evolved the ability to fly. The ground-up theory assumes they were ground animals moving fast by jumping and flapping（ 振 翅 ）their wings. The tree-down theory assumes they were tree climbers that glided（滑行）among branches.
At field sites Ken Dial saw a pattern in young ground birds. They flapped their half-formed wings, making short jumps into the air like popcorn. So to come up with new data on the age-old debate. Ken Dial designed a project to see what clues might lie in how baby birds learned to fly.
He settled on the Chukar as a model species，and brought in some hay bales（千草团）for the Chukars to rest on as a local farmer suggested. To his surprise, instead of lying up, the baby Chukars were using their legs. They run right up the side of a hay bale, flapping all the while. For Ken, this was the“aha” moment, which opened a world of possibilities.
Ken conducted more experiments, filming the birds as they raced up inclines（纤）tipped at increasing angles. As the incline increased, the birds began to lap, but they angled their wings differently from birds in flight. They aimed heir flapping down and backward, using the force not for lift but to keep their feet firmly pressed against the incline. It's exactly like the spoiler on the back of a race car. In Formula One, spoilers are the big aerodynamic（空气动力）fins that push the cars downward as they speed along, increasing power and handling
Ken called the technique WAIR, for wing-assisted incline running. It not only allowed young birds to climb vertical surfaces but also gave adults an energy-efficient alternative to lying In an evolutionary context, WAIR takes on surprising explanatory powers. Ken came up with a reasonable origin for the flapping strokes of birds (something gliding animals don't do and thus a shortcoming of the tree-down assumption) and an aerodynamic function for half-formed wings (one of the main drawbacks to the ground-up theory).
【1】Which is Ken Dial's central assumption in setting up his project?
A．The acquisition（习得）of Night in young birds sheds light on that in bird ancestors.
B．The bird ancestors learned to fly by jumping and lapping their wings.
C．Young birds in a lab setting are less likely than wild birds to require branches.
D．Ground bird and tree-climbing bird ancestors evolved in parallel.
【2】At Ken Dial had his “aha” moment, he________.
A．tried to train the birds to fly to the to the top the inclines.
B．studied existing films to observe the birds' movements.
C．observed how the birds dealt with increasingly steeper inclines
D．consulted with Formula One race car experts about aerodynamic.
【3】According to the passage,which helps the baby Chukar run up the incline?
A．The speed with which they climbed
B．The position of their flapping wings
C．The spoiler on the back of a race car
D．Their continuous jumping movements
【4】Which of the following is TRUE of the technique WAIR?
A．It stops young and adult birds from lying.
B．It proves that the ground-up theory is true.
C．It allows birds to move faster on the ground.
D．It accounts for the birds’ flapping movement.
22、Baby girls make their way to dolls as son as they can crawl(爬), and boys will head for the toy cars, a study has shown. The findings-the first t o show consistent differences in very young babies-suggest there is a biological basis for their preferences.
Psychologists Dr Brenda Todd carried out an experiment involving 90 babies aged 9 months to 36 months. They were allowed to choose from 7 toys. Some were 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 amount of time they spent playing with each toy were recorded.
Of the youngest children (9 to 14 months), girls spent much longer time playing with the doll than boys, and boys spent much more time with the car and the 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’ views on which toys were more appropriate for boys or girls, and the children’s choices.
Dr Brenda Todd said, “Children of this age are already exposed to much socialization. Boys may be given ‘toys that go’ while girls get toys they can care for, which may help shape their preferences. But these findings are consistent with the former idea that children show intrinsic(内在的) interest in particular kinds of toys. There could be a biological basis for their choices. Males through evolution have been adapted to moving objects, probably through hunting instincts (本能), while girls prefer warmer colors such as pink, the color 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 colors better
C. their parents treat them differently
D. there is a biological difference between them
【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. The older the babies are, the more obvious their preference is.
D. Parents should teach baby boys and girls to share each other’s toys.
【3】What conclusion did Dr Brenda Todd draw from the results of the study?
A. Adults purposely influence the preference of babies.
B. Babies’ preference isn’t affected by social surroundings.(环境)
C. Baby boys preferring moving toys will be good at hunting.
D. Baby girls preferring warmer colors will be warmhearted.
【4】Which column of a newspaper does the passage probably appear in?
A. Science. B. Health.
C. Education. D. Entertainment.

24、Crossing your legs is an extremely common habit. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.
A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason is that crossing one leg over the other increases resistance, making it even harder for the blood to circulate and increase your blood pressure. Thus, you shouldn’t have your legs crossed for more than 15 minutes, and it’s important that you get up and walk around at least once every hour.
Crossing your legs can also lead to neck and back pain. Ideally, it’s best for our bodies to sit with our feet planted flat on the floor. When you sit with your legs crossed your hips are in a twisted position, which can cause pressure on your lower and middle back and neck.
You also might notice that when you sit with your legs crossed for long periods of time your feet and legs get painful. This is because when one leg sits on top of the other, it causes pressure on the veins and nerves in your legs and feet. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.
So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.
【1】A study published in Blood Pressure Monitoring showed that .
A. crossing your legs can raise your blood pressure
B. crossing one leg over the other can increase the blood circulation
C. you should have your legs crossed once every hour
D. you should get up and walk around for more than 15 minutes
【2】Crossing your legs can cause some health problems except .
A. pressure on veins and nerves in legs and feet
B. permanent nerve damage
C. unstable posture
D. neck and back pain
【3】What seems to be the writer’s attitude toward crossing legs?
A. Supportive. B. Negative.
C. Casual. D. Confused.
25、The beauty, majesty, and timelessness of a primary rainforest are indescribable. It is impossible to _______ on film, to describe in words, or to explain to those who have never had the awe-inspiring experience of standing in the heart of a primary rainforest.

In 2001, The World Resources Institute estimated that the demand for rice, wheat, and corn is expected to grow by 40% by 2025, increasing irrigation water demands by 50% or more. They further reported that the demand for wood could double by the year 2050; ________, it is still the tropical forests of the world that supply the most part of the world’s demand for wood.
In 1950, about 15 percent of the Earth’s land surface was covered by rainforest. Today, more than half has already gone up in ________. In fewer than fifty years, about half of the world’s tropical rainforests have fallen ________ to fire or deforestation, and the rate of destruction is still ________. Unbelievably, more than 200,000 acres of rainforest are burned every day. That is more than 150 acres lost every minute of every day, and 78 million acres lost every year! More than 20 percent of the Amazon rainforest is already gone, and much more is severely ________ as the destruction continues.

26、阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
A farmer grew some vegetables in his garden. One day his wife was ill and he had no money. He had to sell some cabbages and carrots in the market. The next morning he took two baskets of vegetables to town. But it was snowing hard that afternoon and there were few people in the street. When his vegetables were sold out, it was dark. He bought some medicine and hurried to his village.
On his way home he saw a person lying on the snow. He placed his baskets on the ground and was going to help the person to get up. At that time he found it was a dead man and there was much blood on his body. He was so afraid that he ran away quickly, without taking the baskets with him.
The next afternoon the farmer was sent to the police station. Having shown the baskets, an officer asked, “Are these yours?” “Yes, sir,” the farmer answered timidly. “Have you killed the man?” “No, no, sir,” the farmer said in a hurry. “When did you see the dead man?” “About seven last evening.” “Did you see who killed the man?” “No, sir.” The officer brought out a knife and asked, “Have you seen it before?” “No, sir.” The officer became angry and told the policeman to beat him up and sent him into prison. He wanted to trap the farmer into the confession, but the farmer didn't admit he was the murderer.
Paragraph 1:
The officer was so angry that he asked the policeman to beat him up again.
