阅读下列短文，从每题所给的A、B、C和D项中，选出选项，并在答题卡上将该项涂黑。

A

In , I was swimming off Sunrise Beach with some friends and my brother Taariq, on a life-saving exercise.

Two guys stayed in the boat while Taariq and I swam out. Then something caught my eye – a large shark washeading towards my brother. I shouted to the guys in the boat to get Taariq out and I tried to draw the shark’s attention away from my brother by hitting the water. It worked. But now the shark was swimming towards me.

As the three-metre ―great white‖ circled me, I tried to push it away with my feet. But that only made it angry. It swung its body round, making a huge splash.

I tried desperately to swim away, but my right leg wouldn’t move. I looked down and saw why: everything below my knee was in the shark’s mouth. It was like a dog with a bone, shaking me violently.

I screamed to the guys in the boat for help as the shark took me underwater, still shaking me with my leg in its mouth. I was running out of breath and my lungs felt as if they were on fire.

Then I got so angry, I thought, ―without a fight.‖ I started attacking the shark with all my remaining strength, grabbing its eye and punching its nose.

I gave one last enormous push and heard a great snapping sound. Suddenly, I was free. When I broke the water surface I was close to blacking out.

The boat was nearer now, and Taariq grabbed my hand and started pulling me out. He held my injured leg, trying to stop the bleeding. I didn't know it, but halfway down my leg there was nothing left.

After I left from the hospital, I felt angry about what had happened to me at first. But my brother told me not to give up on life. I followed his advice and less than two years later I was chosen to attend the Beijing Paralympics (残运会).

41. The writer started hitting the water in order to __________.

A. tell his brother a shark was approaching

Children who spend more than two hours a day at a computer or watching television are more likely than others to have mental problems, scientists say.

Researchers found that 11-year-olds who spent several hours in front of a screen each day did worse on mental health tests, no matter how much physical exercise they got.

The study found no direct evidence that sitting in front of a screen actually causes mental health problems. Instead, it suggests that children with difficulties, such as extreme shyness, are more likely to choose TV or computer games than sociable activities.

In the study, children were asked whether they agreed, disagreed or somewhat agreed with a list of statements, including, ―I generally play alone or keep to myself‖ and, ―I am often unhappy, or tearful‖. They were also asked how much exercise they took and how long they spent at a TV or computer screen.

According to the study, children who spent more than two hours a day at a screen had a 60% higher risk of mental problems than children who spent fewer viewing hours. The risk was only slightly higher in children who did little or no exercise.

―Physical activity is good for health in many ways, but it can’t make up for long hours of screen viewing. Parents should consider limiting their children’s screen viewing to no more than 2 hours a day,‖ said the study organizer, Angie Page.

Previous studies have raised concerns that watching too much television can affect children's behaviour in later life. A Canadian study found that those who watched most TV as young children performed worse at school, ate more junk food and had more trouble concentrating.

The Dutch did not invent windmills(风车), but they put them to good use, drying flooded fields to create more farmlands.

Unlike history’s first windmills in Persia centuries ago, which were used to make flour, these machines were pumping systems, bringing up water for families and farm animals from deep underground.

In the U.S.A, windmills were introduced to desert lands around the railroads, which needed water along the tracks for the steam engines. Farmers quickly borrowed the idea and bought a lot of windmills.

These days, you can see hundreds of wind turbines(涡轮机) on top of some California mountains, where the wind always --- or at least most of the time --- steadily blows.

A collection of 3,300 wind turbines on one Californian mountain draws enough energy to supply the power needs of a whole city.

While windmills drove water pumps, wind turbines make electricity that goes directly into the electric system. Electricity companies have discovered the same strengths of wind power that farmers learned a century ago: the wind is a wonderful, non-polluting energy source.

You never run out of it, and the price cannot be beat.

About 1.5 million American children --- or 3 percent of the school-age population --- won't be going anywhere as schools open for the new term.

Before 1918, when Mississippi became the last U.S. state to require that school-age children attend public or private schools, many children were taught by their parents at home or by teachers informally hired by the community. Quite often in the countryside, kids of all ages were taught in the same one-room schoolhouse. Many years later in the 1980s, home-schooling made a comeback when very religious parents persuaded the government to approve the teaching of children at home.

Home-schooling is popular with many parents because they believe that children get their moral values from the people with whom they spend the most time.

Adults who choose to stay home and teach their children often don’t agree with standardized testing, grouping students by age rather than ability, and passing them ahead to the next grade whether or not they've grasped the material.

In home-schooling households, it's not unusual to find several children, ages 4 to 16, being taught together. Older kids help younger ones, as they once did in those one-room schoolhouses.
