It doesn't matter how many times you wash your hands, tiny microbes(微生物) still stay on them. But don't worry. Most microbes don't harm you. Now scientists say the microbes on our hands could be used in a surprising way; fighting crime, according to a recent survey microbes as well as fingerprints(指纹) could be used to identify the criminal. Everyone has his own set of microbes on the hands. That is to say, if you and your best friend were able to see and compare all the microbes on your hands, your hands probably would look different. Some microbes only show up on your hands while others live only on your friend's hands. When you work on a computer you leave the microbes from your hands on the keyboard. The scientists can easily tell the owner of the keyboard by looking at the microbes on it. Even if you don't leave your fingerprints behind, your microbes may give you away. Noah Fierer, a scientist, says, "You can only clean a fingerprint, but you can't sterilize(使无菌) a surface just by wiping(擦) it off." He says that scientists have a lot more work to do before the microbe is used as a useful tool.41. According to the passage,   could be used to identify the criminal.A. fingerprintsB. scientists' handsC. microbesD. fingerprints and microbes on people's hands42. Paragraph 3 tells us that  .A. our hands look similarB. the microbes will make the keyboard dirtyC. we should compare hands oftenD. we have our own sets of microbes43. When you work on computer, the microbes  .A. just stay on our handsB. also stay on the keyboardC. will do harm to youD. will disappear44. From Noah Fierer we know that  A. fingerprints are no longer useful in fighting crime.B. microbes can be found on everyone's hands.C. unlike microbe fingerprints can be cleaned if people wipe them.D. the microbe is used as a useful tool.45. What's the best title of the passage?A. Microbes May Tell Who You AreB. Scientists Say Everyone Has MicrobesC. Noah Fiercer Does Research Into MicrobesD. Fingerprints Help Catch CriminalsB How did ancient people tell time? Natural ways of keeping time In ancient time, people had to use the sun and the moon to tell time. They got up when the sun came up and worked in the fields until the sun went down. Man-made things The sand clock is made of two glass balls joined by a narrow neck. The top ball was filled with sand. The sand slowly moved through the neck into the bottom(底部) ball. People knew the time by watching how much sand fell to the bottom ball. People also made the water clock. They made a small hole near the bottom of a pot. When the water in the pot dripped(滴) out, marking(刻度) inside the pot showed how much time passed. Body clocks in living things Animals' body clock Animals don't need clocks to know time. They have their body clocks. Birds know when to fly to warmer places before winter. Some animals know when to keep more food for the winter. Some fish know when it's time to move up the river and lay eggs. Plants' own clock Plants have their own clocks to keep time. Plants know when to open flowers or when to drop their leaves. Body clock in human beings People also have their own body clocks. When we get used to our lives, our body clocks can be very exact. It can tell us when it's time to wake up. It can also tell us when to eat or to go to sleep.46. How could an ancient farmer know when to go back home from the field in the daytime?A.

A mobile phone is a mobile phone. But can you combine the two to do something for your local environment? As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury(埋葬) it in the garden and wait for it to flower. A biodegradable(生物可降解的) mobile phone was, this month, introduced by scientists. It is hoped that the new type of phone will encourage users to recycle. Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and able to change shape. Overtime it can also break down into the soil without giving out any poisonous chemicals. British researchers used the new material to develop a phone cover that includes a sunflower seed (种子). When this new type of cover turns into waste, it forms nitrates(硝酸盐). These feed the seed and help the flower grow. Engineers have designed a small transparent(透明的) window to hold the seed. They have made sure it only grows when the phone is thrown away. “We've only put sunflower seeds into the cover so far. But we are working with scientists to find out which flowers would perform best. Maybe we could put roses in next time.” Said one scientist. As phone technology is developing so quickly, people are constantly throwing their mobiles away. This means producers are under pressure(压力) to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can change this, according to the scientists.51. After you have finished using the new type of mobile phone,  .A. the phone will do harm to the environmentB. the phone cover will break down easily in the soil you bury itC. it will be recycled by the producersD. it can be sent back to the shops52. Which of the following is wrong about the cover of the new type of phone?A. It can help the sunflower seed after the mobile phone breaks downB. It looks like normal plastics but it can break downC. It includes a sunflower seedD. It makes sure the seed only grows after the phone is thrown away53. The new type of phone can reduce the harm to the environment mainly  .A. because of the material of its coverB. because of the sunflower seedC. because it's made of no poisonous chemicalsD. because you bury it in the soil after you finish with it54. This type of research is done because  .A. the technology that produces mobile phones is changing quicklyB. users are constantly throwing their mobiles awayC. nobody has ever thought of recycling mobile phonesD. producing mobile phones uses a lot of energy, so this has become a very big problem for the environment55. We can guess from the story  .A. the new type of mobile phones is already on the marketB. the new type of mobile phones will sell very wellC. recycling mobile phones is not useful to the environmentD. other flowers may be used in the new type of mobile phones五、单词拼写(单句首字母填空)（共5小题；共5分）56.
