Since the Copenhagen Climate Conference, carrying out low carbon economy and living a low carbon life has been a hot topic. Recently our class had a heated discussion about it. Through the discussion, we are fully aware of the necessity of carrying out a low carbon economy in our country. Fossil fuels have been mainly used for power for quite a long time, thus producing large quantities of greenhouse gases and causing serious pollution. People have paid more attention to economic growth than the environmental protection. / People have given priority to economic growth over the environmental protection. / People have developed economy at the sacrifice of the environment. If the situation continues, sustainable development can’t be ensured. During the discussion, my classmates put forward the following suggestions about how to take a green development path. First, more trees should be planted to expand forest coverage. Second, clean energy and renewable energy should be developed. Third, many of what people throw away should be recycled and reused. We all think it everyone’s duty to live a low carbon life. We should try to save every bit of water and electricity. It’s also important to use public transportation as much as possible. Besides, what’s more important is that we should call on people around us to make contributions to creating a green homeland. 低碳经济下的环境保护 查看更多

 

题目列表(包括答案和解析)

 A few months ago, it wasn't unusual for 47-year-old Carla Toebe to spend 15 hours per day online. She'd wake up early, turn on her laptop and chat on Internet dating sites and instant-messaging programs – leaving her bed for only brief breaks. Her household bills piled up, along with the dishes and dirty laundry, but it took constant complaints from her four daughters before she realized she had a problem.

  "I was starting to feel like my whole world was falling apart – kind of slipping into a depression," said Carla. "I knew that if I didn't get off the dating sites, I'd just keep going," detaching (使脱离) herself further from the outside world.

  Toebe's conclusion: She felt like she was "addicted" to the Internet. She's not alone.

  Concern about excessive Internet use isn't new. As far back as 1995, articles in medical journals and the establishment of a Pennsylvania treatment center for overusers aroused interest in the subject. But as reliance on the Web grows, there are signs that the question is getting more serious attention: Last month, a study published in CNS Spectrums claimed to be the first large-scale look at Internet overuse. The American Psychiatric Association may also consider listing Internet addiction in the next edition. And scores of online discussion boards have popped up, on which people discuss negative experiences tied to too much time on the Web.

    The new CNS Spectrums study was based on results of a nationwide telephone survey of more than 2,500 adults. Like the latest survey, this one was conducted by Stanford University researchers. About 6% of respondents reported that "their relationships suffered because of excessive Internet use." About 9% attempted to conceal "nonessential Internet use," and nearly 4% reported feeling " still occupied by the Internet when offline."

  "The Internet problem is still in its early stage," said Maressa Orzack, a Harvard University professor. No single online activity is to blame for excessive use, he said. "They're online in chat rooms, checking e-mail, or writing blogs. The problem is not limited to porn (色情) or gambling websites.”

  “Excessive Internet use should be defined not by the number of hours spent online but in terms of losses.”said Maressa Orzack. "If it's a loss where you're not getting to work, and family relationships are breaking down as a result, then it's too much."

  Since the early 1990s, several clinics have been established in the U. S. to treat heavy Internet users. They include the Center for Internet Addiction Recovery and the Center for Internet Behavior.

  The website for Orzack's center lists the following among the psychological symptoms of computer addiction:

  ● Having a sense of happiness or excitement while at the computer.

  ● Longing for more and more time at the computer.

  ● Neglect of family and friends.

  ● Feeling empty, depremssed or irritable when not at the computer.

  ● Lying to employers and family about activities.

  ● Inability to stop the activity.

  ● Problems with school or job.

  Physical symptoms listed include dry eyes, backaches, skipping meals, poor personal hygiene (卫生) and sleep disturbances.

  “People who struggle with Internet overuse maybe depressed or have other mood disorders.” Orzack said. When she discusses Internet habits with her patients, they often report that being online offers a "sense of belonging, and escape, excitement and fun," she said. “Some people say relief…because they find themselves so relaxed.”

  Some parts of the Internet seem to draw people in more than others. Internet gamers spend countless hours competing in games against people from all over the world. One such game, called World of Warcraft, is cited on many sites by posters complaining of a "gaming addiction."

  Andrew Heidrich, an education network administrator from Sacramento, plays World of Warcraft for about two to four hours every other night, but that's nothing compared with the 40 to 60 hours a week he spent playing online games when he was in college. He cut back only after a full-scale family intervention (干预), in which relatives told him he'd gained weight.

  “There's this whole culture of competition that sucks people in with online gaming, ”said Heidrich, now a father of two. People do it at the expense of everything that was a constant in their lives." Heidrich now visits websites that discuss gaming addiction regularly “to remind myself to keep my love for online games in check”.

  Toebe also regularly visits a site where posters discuss Internet overuse. In August, when she first realized she had a problem, she posted a message on a Yahoo Internet addiction group with the subject line:“I have an Internet Addiction.”

  “I'm self-employed and need the Internet for my work, but I'm failing to accomplish my work, to take care of my home, to give attention to my children,”she wrote in a message sent to the group. “I have no money or insurance to get professional help; I can't even pay my loan and face losing everything.”

  Since then, Toebe said, she has kept her promise to herself to cut back on her Internet use. "I have a boyfriend now, and I'm not interested in online dating," she said by phone last week. "It's a lot better now."

1. What eventually made Carla Toebe realize she was spending too much time on the Internet?

 A. Her daughter's repeated complaints.

 B. Tiredness resulting from lack of sleep.

 C. The poorly managed state of her house.

 D. The high financial costs adding up.

2.What is the main idea of para4?

A. A study claimed to be the first large-scale look at Internet overuse.

B. The American Psychiatric Association plans to list Internet addiction in its edition.

C. There are heated discussions about negative experiences over internet overuse.

D. There is a growing concern towards internet addiction.

3. According to Professor Maressa Orzack, Internet use would be considered excessive if ______.

 A. it seriously affected family relationships

 B. one visited porn websites frequently

 C. too much time was spent in chat rooms

 D. people got involved in online gambling

4. According to Orzack, people who struggle with heavy dependence on    

the Internet may feel ______.

 A. discouraged   B. pressured    C. depressed    D. puzzled

5. Andrew Heidrich now visits websites that discuss online gaming addiction to _____.

 A. improve his online gaming skills

 B. control his desire for online gaming

 C. show how good he is at online gaming

 D. exchange online gaming experience

6.Which of the following best describes the tone(口吻) of the passage ?

 A. Humorous      B. Ironic       C. Objective      D. Casual

阅读理解

  The kids at Shute Country Primary School in Devon are surprisingly quiet when it's time to go home in the afternoon. Instead of the usual shouting and running you can hear them asking each other,“Are the lights all off?”“Shall we check the taps in case they are dripping?”“How many paper towels did we use today?”

  But it's not unusual here. The kids have declared a war on waste.

  “We've never made the children do anything.”explained Liz Templar, the school's head teacher.“They came up with all the ideas themselves. They're doing this because they want to.”

  If you take a look around the school you won't see anything thrown away unnecessarily. Everything is collected and reused, or sent to be recycled.

  Shute School started its green revolution two years ago. They looked carefully at every part of school life--from the teaching to the cleaning. They looked at the stationery(文具) that was used--especially photocopying, the way cleaning was carried out, and how food was used--and wasted!

  Even parents were looked at: how many children came in each car? Did they use unleaded petrol? Could they bring more children in fewer cars?

  High on the list was the waste of paper. Next came unfriendly cleaning products. Paper towels were replaced with recycled paper, but the hardest thing for the kids was when they found out how much rubbish was created by the chocolate, crisps and other snacks(小吃) eaten at lunch time. Of their own accord(自愿地), the children gave them up. Now they bring apples and home-made snacks.

  The school has its own garden where they grow vegetables and flowers so that they can learn about the environment. They also use this area for their recycling store--large containers to collect aluminium, bottles, paper and fabric(织物).

  Even the school's play area is made from recycled things.

  Since the children started, the school's heating and lighting bills have fallen obviously and the number of rubbish bags has gone down from seven a week to two or three.

  Everywhere in Shute School there are bright posters asking everyone to take their rubbish home, to save energy and paper and to keep the green flag flying.

1.Which of the following is the major information we get from the passage?

[  ]

A.The pupils at Shute School are fighting against air pollution.

B.The pupils at Shute School are learning to save things.

C.The pupils at Shute School have declared a war on waste.

D.The pupils at Shute School have found a way to recycle waste things.

2.Children at Shute Country Primary School bring apples and home-made snacks to school in order to _____.

A.create less rubbish

B.save money

C.obey the school's rules

D.keep their promise

3.We can infer from the text that“green revolution” means _____.

[  ]

A.beautifying schoolyard

B.activity against waste

C.planting green plants

D.throwing away waste

4.What do the children think creates the most waste?

[  ]

A.Paper towels.

B.Cleaning products.

C.Snacks.

D.Paper.

5.We learn from the text that the children's behavior _____.

[  ]

A.has brought arguments

B.has saved the school's cost

C.worried their parents

D.was forced by their head teacher
