¡¾´ð°¸¡¿Nowadays many teenagers show great interest in making friends online. Some people think students should make friends on line? Some people say yes. The internet helps make many friends. Chatting on line, students can more freely express their feelings and opinions, and even get help with their foreign language studies. But others think students should not. They say making friends on line is a waste of time, which should be spent more meaningfully on study. Besides, some students get cheated on line.

It is my opinion that students should place their study, health and safety before other things. As for friendship, we can readily find it in our classmates and other people around us.

Getting electricity has always been a problem for the 173 people living in Nuevo Saposoa, a small village in Peru, South America. However, things went worse in March 2017 after heavy rains damaged the only power cables(µçÀÂ) in the area. The villagers were forced to use oil lamps, which are not only expensive but also dangerous because of the harmful gases they produce.

Luckily, researchers at the University of Technology (UT) in Lima, Peru heard about their problem and found a wonderful method to solve it. They made a lamp that can be powered by plants and soil, both of which can be easily found in the Amazonian rainforest where the village lies. The lamp takes energy from a plant growing in a wooden box and uses it to light up an LED light bulb.

While that may sound amazing and even impossible, the science behind the idea is quite simple. As plants create their food (using the sun¡¯s energy, water and chemicals from the soil), they also produce waste which they return to the soil. Tiny animals in the soil eat this waste and they produce electrons(µç×Ó). The UT team put special sticks inside the soil to get the energy and keep it in the lamp¡¯s batteries for later use. The researchers say a single charge(µçºÉ) can power a 50-walt LED light for two hours£­enough time for local villagers to get their evening work done.

The university gave ten Plant Lamps to the villagers of Nuevo Saposoa in October 2017. So far, they have been a huge success! Elmer Ramirez, the UT professor who invented the lamp, believes the Plant Lamp could help improve the lives of many people, especially small rainforest communities, 42% of whom have no electricity.

Topic: A new invention£­the Plant Lamp

The problem in the small village

The people living in Nuevo Saposoa have much ¡¾1¡¿ getting electricity. However, things went worse for the only power cables there were destroyed by heavy rains. The villages had to use oil lamps, although they are expensive to use and can be bad for people¡¯s health.

The method to solve the problem

¡ïSome researchers made a new kind of lamp. It can be powered by¡¾2¡¿ objects found in the rainforest£­plants and soil.

¡ïThe lamp takes energy from a plant growing in a wooden box and uses it to light up an LED light bulb.

The science explanation

¡ïPlants create their food and produce waste which is¡¾3¡¿ to the soil at the same time. Some tidy animals feed on the waste and produce electrons.

¡ïThe UT team can get the energy and keep it in the lamp¡¯s batteries. A 50-walt LED light can be powered by a single charge for local villagers to¡¾4¡¿ their evening work.

Conclusion

Ten Plant Lamps were given to the villagers in October 2017 and they have been very¡¾5¡¿ since then. Elmer Ramirez, the inventor of the lamp, believes that they could be the most helpful for the small rainforest communities.

¡¾ÌâÄ¿¡¿In today¡¯s world many people seem to be hungry for money. Some of them even lose their lives for it. Money does have its most useful effect(Ó°Ïì)on the poor£¬but once a person has a rich life£¬a lot more money doesn¡¯t mean more happiness.

¡¾ÌâÄ¿¡¿ Many people say that they are working too many hours. They don¡¯t have enough time to relax or stay with their family.

Work hours are different from one country to another. In France, people spend about 1,646 hours a year at work. In Japan, however, people work about 2,259 hours a year. That means a Japanese worker works 513 more hours a year than a French worker.

Why do people work so many hours? Some people work extra hours because they want to make more money. However, many companies don¡¯t pay over time. Their workers don¡¯t get more pay for more work. These people think it¡¯s their duty to wore more hours. Some are afraid of losing their job if they don¡¯t work more hours. Many people say that their vacations are too short. In France, people get five weeks of paid vacation a year. In Germany, they get from four to six weeks, and in the United States, two weeks. One study shows fewer than half of workers used all their vacation days. In Great Britain, there is a saying, ¡°All work and no play makes Jack a dull (³Ù¶ÛµÄ) boy.¡± ¡°If that is true, there must be a lot of dull people in the world.¡±

How to ride a bicycle in traffic

Cycling in traffic is something that seems dangerous but can be quite safe as long as you obey the rules of the road and exercise alertness (»úÃô)and common sense. Here are some tips for you.

¡¾1¡¿A helmet(Í·¿ø) won¡¯t prevent accidents. But it can save you from serious head injuries if you are in an accident. That¡¯s why it¡¯s always safer to wear it when cycling.

¡¾2¡¿ So always have lights if it is not very bright out, and if you cycle in the evening, reflective clothing is a great idea. The more obvious you are to drivers, the less likely they are to hit you.

¡¾3¡¿Start from the easy streets. Pick some quiet back streets and get used to being around cars and other road traffic Gradually build up your stamina(ÄÍÁ¦) on larger roads by practicing on them on quiet days.

¡¾4¡¿ Always ride with the traffic. Stay off sidewalks, stop for red lights, stop at stop signs, and obey all other traffic signs. Don¡¯t run red lights no matter how many other cyclists do it. Your good habits can help improve others¡¯ safety awareness.

¡¾5¡¿ If you need to talk on your cellphone, stop and pull over. Don¡¯t listen to an MP3 player or radio. Some cars are very difficult to hear, so you need to pay careful attention to not get run over by them.

A. The wearing of helmets is a requirement in many countries.

B. If you¡¯re an inexperienced cyclist, it is not a good idea to throw yourself in the heavy traffic.

C. Make sure you are comfortable with your bike.

D. You should always pay attention to the rules of the road.

E. Most accidents happen when drivers haven¡¯t noticed a cyclist.

F. Avoid doing things that will affect your ability to hear cars coming up behind you
