【題目】Teenagers are known for being creative and full of new ideas. Let’s have a look at these teenage inventions that might change the world.

Banana leaves usually go bad in two or three days. Tenith Adithyaa, a teenager from India, used UV to make the leaves stay fresh for a year. Tenith thinks that one day the leaves will be used for making plates, cups and other things.

David Cohen, an American teenager, built an earthworm(蚯蚓) robot. It is able to go into the smallest places, where humans or dogs can’t go. It will be used for finding people in a fire or an earthquake.

Remya Jose, a 14-year-old from India, found it tiring and boring to handwash clothes in the nearby river. She reused some bicycle parts and created a washing machine that saves time, energy and keeps people fit at the same time.

Kenneth Shinozuku, a 15-year-old from New York, noticed that his grandfather who got Alzheimer＇s disease（老年癡呆） would often leave home and get lost. So he invented the wearable sensors(感應(yīng)器)to help people find their family members like his grandfather.

【題目】Old Dawson had the best apples in town,but kids knew they mustn't go into his yard to pick a delicious apple,even off the ground,because Dawson,a bad-tempered(壞脾氣的)man,they said,would come after you with his gun.

One Friday,12-year-old Janet was going to stay all night with her friend Amy.They had to walk by Dawson's house on the way to Amy's house.Like most of the children,Janet was scared of the old man because of the stories she'd heard about him.

Amy said that Mr.Dawson wouldn't hurt anyone.Still,Janet was growing more nervous with each step closer to the old man's house.When they got close enough,Dawson looked up with his usual frown(皺眉),but when he saw it was Amy,a big smile changed his whole face as he said,“Hello,Miss Amy.I see you've got a little friend with you today.”

Amy smiled back and told him Janet was staying overnight and they were going to listen to music and play games.Dawson told them that sounded fun,and offered them each a fresh picked apple off his tree.

As they walked on,Janet asked Amy,“Everyone says he's the meanest man in town.Why was he so nice to us?”

Amy explained that when she first started walking past his house, he wasn't very friendly and she was afraid of him,but she always smiled at him.It took a while,but one day he half-smiled back at her.

After some more time,he started smiling real smiles and then started talking to her.Just a“hello” at first,then more.She said he always offers her an apple now,and is always very kind.

【題目】A Cloud of Hope and Danger

A small cloud floats through the air in a hospital operating room. In the room a patient, suffering from cancer, lies on a table. The cloud surrounds(包圍) the patient, covering her body and filling her lungs(肺). The cloud is not smoke or steam. It is made of millions of microscopic robots called nanorobots(納米機(jī)器人). These tiny robots move from cell(細(xì)胞) to cell in the patient’s body, destroying the cancer.

Fighting cancer with nanorobots is only an idea today, but scientists say that it could be possible in the future. Using nanorobots for good purposes such as fighting disease or repairing the environment may be the solution to many of today’s problems.

However, nanorobots could be a dangerous risk as well. Since nanorobots are so tiny, they will have to work in large teams of many thousands to many millions. For this reason, nanorobots will have to be programmed to build themselves. Scientists will not have the ability to build millions of nanorobots one by one.

This ability to reproduce is making some scientists worried. What if something goes wrong in the programming? Quite a lot of crazy nanorobots would be far worse than any disease. Some people think that if they get out of control, nanorobots could destroy the Earth.

What should be done? Should we continue researching nanorobots or should we search for other methods? This is one of the many difficult decisions that we have to make in the future.

【1】What is the cloud in the passage, smoke and steam or microscopic robots?

________________________________________________________________________

【2】What can be the good use of nanorobots for us?

________________________________________________________________________

【3】Why will nanarobots have to work in large teams?

________________________________________________________________________

【4】What makes it possible for nanorobots build themselves?

________________________________________________________________________

【5】Can you give the passage another title?

________________________________________________________________________

【6】Are you for or against using nanorobots in the future? Why?
