If you are worried about the planet，please make sure your rubbish is buried under ground.
People talk about "reduce，reuse and recycle”. It sounds like a good idea. There is a problem，though. Recycling costs too much money.
Even the US Environmental Protection Agency（EPA）says it only makes sense economically and environmentally to recycle about 35 percent of abandoned（废弃的）materials. Among those materials are paper and aluminum cans. Recycling 1 ton of paper or aluminum cans，the agency says，can save about 3 tons of CO2emissions（排放物）over producing those materials anew. Paper producers pay for the trees they process. If it were cost-effective to recycle paper，producers would beat down your door to buy it. But it isn't. That means it's more expensive to recycle old paper than to cut trees and then replant trees for processing.
Plastic can be recycled too. Given the recent drop in crude oil prices，it is now cheaper to make a new plastic container than to recycle an old one. Even if that is not true，the EPA says that recycling a ton of plastic saves only about a ton of CO，.However，it doesn't take into account the water most consumers use to wash their plastic containers before having them recycled. The New York Times journalist John Tierney recently wrote, "If you wash plastic in water that was heated by electricity, then the effect of your recycling could be more carbon in the atmosphere."
Glass is another recyclable material. To reduce greenhouse gas emissions by 1 ton you have to recycle 3 tons of glass. If one includes the cost of collecting glass waste from neighbourhoods, and the pollution produced by the collection trucks and the recycling process itself, glass recycling creates more greenhouse gas emissions and is more expensive than making new glass, which comes primarily from sand that exists everywhere.
If recycling were truly cost-effective, private companies would line up on your doorstep to buy your rubbish. Don't look now because they' re not there.
1. What's the EPA's attitude to recycling aluminum cans
A. It is helpful to the environment.
B. It is actually a waste of money.
C. It costs less than recycling paper.
D. It costs the same as producing new cans.
2. What increases the cost of recycling plastic
A. The crude oil.
B. The water pollution.
C. The process of cleaning it.
D. The electricity for lights.
3. What can be learnt about making new glass
A. It results in lots of waste in neighbourhood.
B. The material for new glass can be easily got.
C. It is slightly more expensive than recycling glass.
D. Making 3 tons of new glass produces 1 ton of CO2 emissions.
4. What does the author mean by saying the underlined sentence
A. Recycling will disappear soon.
B. Companies will line up on your doorstep.
C. Recycling is a way to deal with your rubbish.
D. Companies won't bother to collect discarded materials.

How to Do Man-on-the-street Interviews
The man-on-the-street interview is an interview in which a reporter hits the streets with a cameraman to interview people on the spot. 1 But with these tips, your first man-on-the-street interview experience can be easy.
· When your boss or professor sends you out to do man-on-the-street interviews for a story, think about the topic and develop a list of about ten general questions related to it. For example, if your topic is about environmental problems in America, you might ask,"Why do you think environmental protection is important in America " 2
· Hit the streets with confidence. 3 Say, "Excuse me, I work for XYZ News, and I was wondering if you could share your opinion about this topic." This is a quick way to warm people up. Move on to the next person if someone tells you he/she is not interested in talking on camera. Don't get discouraged.
· 4 Each interview that you get on the streets shouldn't be longer than ten minutes. As soon as you get the answer you need, move on to the next person. Make sure that as you go from interview to interview, you are getting a variety of answers. If everyone is giving you the same answer, you won't be able to use it. A safe number of interviews to conduct is about six to ten. 5
·If your news station or school requires interviewees to sign authorisations（授权书）to appear on the air，don't leave work without them.
A. Limit your time.
B.As you approach people，be polite.
C. If you don't own a camera，you can buy one.
D. For new reporters，this can seem like a challenging task.
E. To get good and useful results，ask them the same question.
F. That number of interviews should give you all the answers you need.
G. With a question like this，you will get more than a “Yes” or “No” reply.

[山东胶州2021高二期中]阅读下面短文，根据其内容写一篇60词左右的内容概要。
In the past，most people exercised every day. They didn't exercise on purpose. Instead，they exercised by working the land and by walking everywhere. Now，however，people do not take as much exercise. Many people work in offices or factories where they do not have to move around very much. Now that cities are so big，few people walk to work. They drive or travel by bus or train. With modern telecommunications technology，they don't have to move around to get messages delivered. What they have to do is just to press buttons on their phones or other devices.
Because of this unhealthy modern lifestyle，many people try to exercise in other ways. Jogging and running are very popular. Going to the gym is also a popular way of getting exercise. Many women prefer to go to aerobic（有氧的）classes at the gym. In these classes，music is played loudly and an instructor shouts out instructions for the exercises. The people in the class run，stretch and jump around for an hour or more. Men and women also do weight training at the gym. They lift heavy weights to build up their muscles.
Although thousands of people do these sorts of exercise every day，some experts believe that they are actually bad for the body. Running on hard surfaces like roads can damage your feet and knees，and aerobics and weight training can be dangerous if the instructor is not properly trained. It's easy to hurt yourself if you lift heavy weights or exercise hard for a long time.
The experts believe that more gentle forms of exercise are better. They advise people to walk more as it is one of the best ways to exercise and does not damage the body at all. They also suggest traditional Chinese exercise such as Tai Chi because these activities are better for the body than hard，fast activities like running. Tai Chi trains your flexibility and improves your sense of balance. Meanwhile，it has the least harmful effects on your joints and knees.

【语篇导读】本文为一篇议论文。作者就垃圾的回收利用进行探讨：回收利用听起来很好，但回收过程耗费的成本较高。
1.A推理判断题。根据第三段中的Recycling 1 ton of paper or aluminum cans，the agency says，can save about 3 tons of CO，emissions over producing those materials anew.可知，美国国家环境保护局认为与制造新的铝罐相比，回收利用铝罐可以减少二氧化碳的排放，所以，美国国家环境保护局认为回收利用铝罐对环境是有帮助的。故选A项。
2.C细节理解题。根据第四段中的However，it doesn't take into account the water most consumers use to wash their plastic containers before having them recycled.和最后一句可知，如果把清洗塑料容器的过程考虑在内，回收塑料的成本就会增加。故选C项。
3.B细节理解题。根据第五段中的.…glass recycling creates more greenhouse gas emissions and is more expensive than making new glass，which comes primarily from sand that exists everywhere.可知，制造新玻璃的材料到处都是，很容易获得。故选B项。
4.D词义猜测题。根据全文讲的回收物品成本较高以及最后一段可知，作者认为如果回收物品真的可以节约成本，私人企业一定会在你家门口排队购买你的垃圾，但是别四处看了，因为他们没在门口。作者是用了戏谑的方式，再次强调自己的观点：回收利用旧物的成本太高，企业不会费心收集废弃材料。故选D项。
【方法总结】
阅读理解中作者有时会通过使用习语、俗语或一语双关来表达观点，猜测此类表达的意思时不能只从字面去理解，一定要先理解文章及段落大意，进行合理的推断，选出最佳选项。如本篇阅读中的第4题，先要理解本文大意及作者的观点，从而理解画线句的含义。
