B 　　On a sunny day last August, Tim heard some shouting. Looking out to the sea carefully, he saw a couple of kids in a rowboat were being pulled out to sea. 　　Two 12-year-old boys, Christian and Jack, rowed out a boat to search for a football. Once they’d rowed beyond the calm waters, a beach umbrella tied to the boat caught the wind and pulled the boat into open water. The pair panicked and tried to row back to shore. But they were no match for it and the boat was out of control. 　　Tim knew it would soon be swallowed by the waves."Everything went quiet in my head," Tim recalls(回忆). "I was trying to figure out how to swim to the boys in a straight line." 　　Tim took off his clothes and jumped into the water. Every 500 yards or so, he raised his head to judge his progress. "At one point, I considered turning back," he says. "I wondered if I was putting my life at risk." After 30 minutes of struggling, he was close enough to yell to the boys, "Take down the umbrella!" Christian made much effort to take down the umbrella. Then Tim was able to catch up and climb aboard the boat. He took over rowing, but the waves were almost too strong for him. 　　"Let’s aim for the pier(码头)," Jack said. Tim turned the boat toward it. Soon afterward, waves crashed over the boat, and it began to sink. "Can you guys swim" he cried. "A little bit," the boys said. Once the were in the water, Tim decided it would he safer and faster for him to pull the boys toward the pier. Christian and Jack were wearing life jackets and floated on their backs. Tim swan toward land as water washed over the boys’ faces. 　　“Are we almost there" they asked again and again. "Yes," Tim told them each time. After 30minutes, they reached the pier.Why did the two boys go to the sea

A:To go boat rowing. B:To get back their football. C:To swim in the open water. D:To test the umbrella as a sail.

To swim across the English Channel takes at least nine hours. It’ s a hard work and it makes you short of breath. To fly over the Channel takes only twenty minutes ( as long as you’ re not held up at the airport), but it’ s an expensive way to travel. You can travel by hovercraft if you don’ t mind the noise, and that takes forty minutes. Otherwise you can go by boat, if you forget your sea-sickness ills. All these means of transport have their problems and the weary(不耐烦的) traveler often dreams of being able to drive to France in his own car. "Not possible", you say. Well, wait a minute. People are once again considering the idea of a Channel tunnel or bridge.
This time, the Greater London Council is looking into the possibility of building a Channel link straight to London. (79) A bridge would cost far more than a tunnel, but you would be able to go by rail or by car on a bridge, whereas a tunnel would provide a rail link only.
Why is this idea being discussed again Is Britain becoming more conscious of the need for links with Europe as a result of joining the EEC(欧共体) Well, perhaps. The main reason, though, is that a tunnel or bridge would reach the twenty square kilometers of London’ s disused dockland(船坞地). A link from London to the continent would stimulate trade and re-vitalize(使…各新有活力) the port, and would make London a main trading center in Europe. (80)With a link over the Channel, you could buy your fish and chips in England, and be able to eat them in France while they were still warm!
Which of the following statements is TRUE

A:Swimming across the Channel takes less than four hours. B:The idea of a Channel tunnel or bridge is a very new one. C:It is considered to be more difficult to swim across the channel than any other means. D:A tunnel or bridge would only reach as far as the coast.

The Northern Pike is a very bad fish. It is a big, hungry fish, and swallows little fish such as trout and perch. Many Northern Pikes live in Lake Davis. They are killing all the smaller fish in the lake. The Northern Pike are a serious threat to the lake because they eat all the smaller fish. Soon, all other species of fish in the lake will be killed off. This is not healthy for the environment.
Experts are afraid that the Northern Pike will swim out of Lake Davis through many smaller rivers that feed into the lake. They could spread all over the country and damage many other water environments. If that happens, it would be too late to stop the Northern Pike.
For ten years, officials have been trying to remove the Northern Pike from Lake Davis. They haw. tried using nets, explosives and poisons. However, the Northern Pike population is still doing well in Lake Davis. Many people do not like the idea of using poison to kill the fish. They worry that the poi- sons are bad for humans who use the water. No trace of the poisons has ever been found in local wells, however.
Scientists are going to try the poison again. This time, they will drain the lake before they add the poison to the water. A public hearing will be held to talk about the problem.
What are the experts afraid will happen

A:The Northern Pike will die. B:The wells will be polluted. C:Poisons will kill the Northern Pike. D:The Northern Pike will swim into other lakes.
