Read the following article and select the best answer. Article: The earth is 4 600 million years old. We humans have lived on earth for only 35 000 years, but during this period we have changed our planet a lot in many ways. Some things we've done are very good for the earth while some are bad. All over the world, people have cut down millions of trees. When it rains or when the wind blows, the earth is taken away. Forests have become deserts, so more and more sorts of animals and plants are disappearing. In big cities, cars and buses have polluted the air. Many people in cities now have health problems. Factories have also polluted the land and the water. As a result, many rivers and lakes are now dead. Around the earth, there's a special kind of oxygen called "ozone"(O3). It is important to the earth. But now air pollution is destroying it and that has made a very big hole in the ozone layer. Too much harmful radiation from the sun passes through the hole and reaches the earth directly. This is very dangerous because this kind of radiation can cause cancer. Carbon dioxide (CO2) in the air has increased a lot. It mainly comes from burning oil, coal and wood. This has formed a "blanket" around the earth. The heat from the sun can't escape so the temperature is rising. This is called "the greenhouse effect". It causes the level of the oceans to rise and the climate of the earth to change. All these problems are very serious, so we must do something now. ,A, B, C, D. Question: The level of the oceans is rising because of _ . - pollution - few trees - the greenhouse effect - changes in the climate

A young man greeted me with a sweet smile. He looked like not a salesman but a student like me. I sensed a strange feeling -- as if I had met him before. He began patiently showing me each model. With his help, I decided to buy one computer with enough functions at a very low price. I enjoyed this shopping experience because of his smile. A few months later, something was wrong with my computer. I went back to the store to have it fixed. When I arrived there, what I saw was still his smile.

Q: Read the following article and select the best answer. Article: Dolphins are not fish. They are mammals .They live in groups and speak to each other in their own language. But they are quite different from almost all land animals. Their brain is as big as men's and they live a long life at least 20 or 30 years. Like some animals, dolphins use sounds to help them find their way around. They also use these sounds to talk to each other and to help them find food. They do not use their ears to receive sounds,but use the jaw--the lower part of the mouth. It is strange that dolphins are friendly to men, and for thousands of years, there are many stories about dolphins and men. In the 19th century, in a dangerous part of the sea near New Zealand,there was a dolphin. The seamen liked him very much and gave him a very good name, Jack. From 1871 to 1903 ,Jack met every boat in the area and showed it the way. In 1903 a passenger on a boat with the name of The Penguin shot and hurt Jack. Luckily the dolphin didn't die, and after a long time he was well again. He guided the ships through the area for nine more years, but he refused to help the boat of the Penguin. Today, some people still kill dolphins, but many countries in the world now protect them. In these places, people are not allowed to kill them. Question: How do dolphins find their way? - They use their noses to smell the way. - They use their ears to hear the sounds. - They use their eyes to see the way. - They use sounds to find the way.
A: They use sounds to find the way.

Q: Read the following article and select the best answer. Article: Sarah ran in, shouting, "Look what I found!" Over the top of the paper I was reading; came a terrible thing that caused me to jump. It was a snake skin found in our garden. "Isn't it beautiful?" said my seven-year-old daughter. I opened my eyes widely and looked at the snake skin in fear . I didn't think it was beautiful, but I learned never to appear nonchalant with children. Everything they see for the first time is important to their sense of beauty; they see only excellence in the world. "Why does it do this?" Sarah asked. "Snakes shed their skins because they need to renew themselves," I explained. "Why do they need to renew themselves?" Sarah asked. "We often need to shed our skins, those coatings that we cover ourselves with," I said to my daughter. "We leave some things and find other thing unwanted or unnecessary. This snake no longer needs this skin. It is probably too little for him, and he probably doesn't think he looks as smart in it as he once did. " As we talked, I knew that she began to understand. Although she couldn't understand clearly, she would know that renewal is part of progress; that we need to take a good look at ourselves, our rooms, schoolwork and spirit, and see what we need to keep and what we need to leave. I was careful to tell that this is a natural way, not one to be forced. "Snakes don't peel off their skins when they like them. "I explained. "It happens as a natural thing of their growth. " "I see, Dad," said Sarah as she held the snake skin, and then ran off. I hoped she would remember this; we need to throw some away because they are worthless or unnecessary. Then we can store them as memories in our deep hearts. Question: Father jumped up when her daughter came to him with a snake skin because _ . - he didn't want to read any more - he was in great fear of it - he wanted to praised her daughter - he hated snakes
A: he was in great fear of it
