The number of penguins have decreased(减少) by 30% since 1987. 　　Penguins are black and white birds that live in the southern part of the world. They are common in South America，New Zealand，Australia and South Africa. Mary live near cold waters. But some live near warm waters in Galapagos Islands. Penguins cannot fly，but they are fine swimmers. Penguins eat fish and krill(磷虾). 　　The warming of the earth is the decrease in penguin populations. The heating of the air has caused ocean waters to become warmer. Higher water temperatures have reduced the supply of fish and krill. Some years later these birds are completely unable to reproduce(繁殖).　 Besides，many adult penguins die of hunger. 　　Widespread(广泛的) fishing，exploration for oil and oil leaks(漏) also make penguins be in danger. Poisonous organisms(生物) in ocean water are another danger. Penguins also have their enemies，including wild dogs，sharks，seals and sea lions. 　　News about penguins is not all bad，however. Several years ago，oil leaking from a ship hurt 40% of the penguins in South Africa. The penguins became covered with oil. But thousands of people helped clean and treat the birds well. Then they returned the penguins to the wild. Now these South African penguins are reproducing in higher numbers than before the oil leaking. 1. Penguins ___________. A. can swim better than fly B. can be found near Oceania (大洋洲) C. eat fish only D. live only in cold waters. 2. Which of the following is NOT the cause of penguin's decrease in numbers? A. Oil searching.　　　　　　  B. Widespread fishing.[来源:学科网ZXXK] C. Human's killing.　　　　　  D. Warming of the oceans. 3. Why are the penguins in South Africa reproducing in higher numbers than before the oil leaking? A. Because people removed the ship. B. Because people sent a lot of penguins to the wild. C. Because people helped the penguins. D. Because people treated the penguins well. B Have you ever been ill? When you are ill，you must be unhappy because your body becomes hot，and there are pains all over your body. You don't want to work，you stay in bed，feeling very sad. 　　What makes us ill? It is germs(细菌). Germs are everywhere. They are very small and you can't find them with your eyes，but you can see them with a microscope. They are very small and there could be hundreds of them on a very small thing. 　　Germs are always found in dirty water. When we look at dirty water under the microscope，we shall see them in it. So your father and mother will not let you drink dirty water.[来源:Zxxk.Com] 　　Germs aren't found only in water. They are found in air and dust. If you cut your finger，if some of the dust from the floor goes into the cut(割开处)，some of the germs would go into your finger. Your finger would become big and red，and you will have much pain in it. Sometimes the germs would go into all of your body，and you would have pain everywhere. 1. Which of the following is TRUE? A. If things are very small，they are germs. B. If things can't be seen，they must be germs. C. Germs are only in dirty water. D. Germs are everywhere around us.[来源:学.科.网Z.X.X.K] 2. What is a microscope used for? A. Making very small things look much bigger. B. Making very big things look much smaller. C. Helping you read some newspapers. D. Helping you if you can't see things clearly. 3. Why don't your parents let you drink dirty water? A. You haven't looked at it carefully.　 B. Water can't be drunk in this way. C. There must be lots of germs in it.　 D. Water will make you ill. 4. Which of the following is NOT true? A. Germs can be found both in water and in the air. B. Germs can go into your finger if it is cut. C. If your temperature is not OK，there must be germs in your body. D. If your finger isn't cut，there aren't any germs on it. 5. What's the main idea of the passage? A. Germs may make us ill.　　　 B. Germs are in dirty water. C. Don't drink dirty water.　　　　D. Take care of your fingers. 1 / 1 学科网（北京）股份有限公司 $
