A
Look closely at your hands. Are they clean? 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. fingerprints
B. scientists' hands
C. microbes
D. fingerprints and microbes on people's hands
42. Paragraph 3 tells us that ?.
A. our hands look similar
B. the microbes will make the keyboard dirty
C. we should compare hands often
D. we have our own sets of microbes

A. just stay on our hands B. also stay on the keyboard
C. will do harm to you D. will disappear
44. 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.

C. Noah Fiercer Does Research Into Microbes
D. Fingerprints Help Catch Criminals
B
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.

C
A sunflower is a sunflower. 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 environment
B. the phone cover will break down easily in the soil you bury it
C. it will be recycled by the producers
D. it can be sent back to the shops
52. 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 down
B. It looks like normal plastics but it can break down
C. It includes a sunflower seed
D. It makes sure the seed only grows after the phone is thrown away
53. The new type of phone can reduce the harm to the environment mainly ?.
A. because of the material of its cover
B. because of the sunflower seed
C. because it's made of no poisonous chemicals
D. because you bury it in the soil after you finish with it
54. This type of research is done because ?.
A. the technology that produces mobile phones is changing quickly
B. users are constantly throwing their mobiles away
C. nobody has ever thought of recycling mobile phones
D. producing mobile phones uses a lot of energy, so this has become a very big problem for the environment
55. We can guess from the story ?.
A. the new type of mobile phones is already on the market
B. the new type of mobile phones will sell very well
C. recycling mobile phones is not useful to the environment
D. other flowers may be used in the new type of mobile phones

You can't always predict a heavy rain or remember your umbrella. But designer Mikhail Belvacv doesn't think that forgetting to check the weather report before heading out should result in you getting wet. To protect people from the rain, he created lampbrella, a lamp post with its own rain sensing umbrella.
The designer says he comes up with the idea after watching people get wet on streets in Russia. "Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be all right to have a canopy(伞蓬) built into a street lamp." he said.
The lampbrella is a street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella in need. Sensors(传感器) then make sure that the umbrella offers the walkers whenever it starts raining.
In addition to the rain sensor, there's also a 360° motion sensor on the street lamp which finds out whether anyone's using the lampbrella. After three minutes of not being used the canopy is closed.
According to the designer, the lampbrella would move at a low speed, so as not to cause harm to the walkers. Besides, it would be grounded to protect from possible lightning strike. Each lampbrella would offer enough protection for several people. Being fixed at 2 meters off the ground, it would only be a danger for the tallest of walkers.
While there are no plans to take lampbrella into production, Belyacv says he recently introduced his creation to one Moscow Department, and insists this creation could be fixed on my street where a lot of people walk.
根据短文内容，完成下列小题。
81. Who designed lampbrella?
? ? ? ? ?
82. Why did Belyacv create lampbrella?
? ? ? ? ?
83. How soon is the the canopy closed if it's not being used?
? ? ? ? ?
84. Would each lampbrella offer enough protection for only one person or several people?
? ? ? ? ?
85. What is the main idea of the passage?
? ? ? ? ?
