As free as they make us, mobile phones still need to stay close to a power source. Soon that may change with "green" power.

Three Chilean students got the idea for a plant-powered device(装置) to charge their cellphones, while sitting in their school's outdoor courtyard during a break from exams, with dead mobile phones. Then, one of them had an "aha" moment.

“It occurred to Camila to say about plants, "said inventor Evelyn Aravena. "Why don't you have a socket, if there are so many plants? 'After that, we thought, why don't they have a charging outlet? Because there are so many plants and living things that have the potential to produce energy, why not? ' "

Their invention — a small biological circuit called E-Kaia - uses the energy plants to produce during photosynthesis(光合作用). A plant uses only a small part of that energy and the rest goes into the soil, and that's where the E-Kaia collects it. The device plugs into the ground and then into your phone.

"It's the most amazing project I've ever seen in my life, plain and simple. They brought this original model, and it worked — and that's when it all changed, at least from my personal point of view and I began to support them. " said Mauricio Cifuentes.

The device solved two problems for the engineering students — they needed an idea for a class project, and an outlet to plug in their phones.

"Looking for a place to charge the notebook, which had no power, and the mobile phones, we weren't able to find anything because all the other students were in the same state of madness trying to find a place to charge their devices," said Aravena.

But plants are everywhere, and the biocircuit makes the best of their excess(过多的) power.

The E-Kaia doesn't carry much charge but it's powerful enough to completely recharge a mobile phone in less than two hours.

The student inventors have applied for patents on their technology, and expect the E-Kaia to go on sale in December 2016.

1.How could the students get the "green" power idea?

A. By carrying out an experiment.

B. Just from an occasional thought.

C. With the support of their professors.

D. Enlightened(启发) by the information in a science book.

2.How does the device work?

A. By using the energy during photosynthesis.　　 B. By using a small biological circuit.

C. By using the electricity stored in the device.　　 D. By using a device buried in the ground.

3.What can we learn from what Mauricio Cifuentes said?

A. He intended to buy the patent.

B. The device was made in a rough way.

C. He showed great interest in the device.

D. He attempted to produce the device in large numbers.

4.What might be the best title for the passage?

A. A New Device to Change the World

B. Green Power - A New and Potential Source

C. Chilean Students Find A Green Way to Charge Phones

D. A New Device Invented by Chilean Students Will Be on Sale

Across the world, mobile phones are very popular with young people. They think that the phones are more than a means of communication — having a mobile phone shows that they are cool and connected.

The explosion in mobile phone use around the world has worried some health professionals. Some doctors are concerned that in the future many people will suffer from health problems because of the use of mobile phones. But mobile phone companies say that there is no proof that mobile phones are bad for health.

On the other hand, why do some medical studies show changes in the brain cells of some people who use mobile phones? Signs of change in the tissue (组织) of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at a young age due to the fact that he couldn’t remember even simple tasks. The man had been talking on his mobile phone for about six hours a day for a couple of years. His family doctor blamed his mobile phone use.

What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

As the discussion about their safety continues, it appears that it is better to use mobile phones less often. Use a normal phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. So, for now, it is wise not to use your mobile phone too often.

高三英语阅读理解简单题查看答案及解析

Most children now chat daily either online or through their mobile phones. They are connecting to a huge number of other children all over the world. Some are shy “in real life” but are confident to communicate with others online; others find support from people of their own age on relationship issues, or problems at home.

Sometimes the online world, just like the real world, can introduce problems, such as arguments. Going online is great fun, but there are also a few people who use the Internet for offensive (冒犯性的) or illegal aims. Children must be made aware of both the good things and the dangers.

To keep children safe your management must cover the family computer. Just as you decide which TV programs are suitable, you need to do the same for the websites and chat rooms your children visit. Remind your children that online friends are still strangers. Reminding them of the risks will keep them alert (警惕).

Computer studies are part of schoolwork now, so it’s likely that your children may know more than you do. We get left behind when it comes to the latest gadgets and the interactive areas of websites, like chat rooms and message boards, which are especially strange. The language of chat is strange to many parents, too. Chatters love to use abbreviations (缩写) such as: atb — all the best, bbfn — bye bye for now, cul8er — see you later, gr8 — great, Idk — I don’t know, imbl — it must be love, kit — keep in touch, paw — parents are watching, lol — laugh out loud, xlnt — excellent!

1.The passage is meant for ______.

A. children　　 　 B. parents

2.Which of the following will the author probably agree with?

A. The Internet is no good for children.

3.In order to keep children safe online, you’d better ______.

A. choose suitable websites and chat rooms for them

B. teach them to use correct net words

C. surf the Internet together with them
