Methane gas forms when organic matter breaks down and is drawn off from large rubbish tips by pipes sunk into the middle of the waste. Until now this process wasn’t possible on small sites because the pipe allowed oxygen to seep in and that stop the breakdown process.
Viktor Popov of the Wessex Institute of Technology has now developed a system to modify existing landfill sites by making them airtight while the methane is extracted from sunken wells. The site is covered by a special three-layered skin whose two outer layers are made of clay with a pressurized(加压的)layer of carbon dioxide gas in the middle. As the methane is sucked out through a central well it is replaced by carbon dioxide from the middle layer rather than oxygen, allowing the breakdown process to continue.
Unfortunately there are no plans to use the power of methane even though Popov claims his invention could provide a valuable source of energy over the next 20 years.
小题1:The passage mainly introduces ______ to us.
A.how to make methane | B.a new way to make use of rubbish |
C.the valuable things in rubbish | D.the amount of rubbish beig reused |
A.in Europe 94 billion cubic meters of methane is produced every year |
B.some of the waste will explode if it is not burnt off |
C.99% of the rubbish has been burnt off in Europe |
D.only a very small part of this kind of energy is used in Europe |
A.methane gas | B.the long pipe | C.oxygen | D.the rubbish |
A.Oxygen can cause the breakdown process to stop. |
B.When the methane is sucked out, oxygen will enter from the middle layer. |
C.Carbon dioxide doesn’t affect the breakdown process. |
D.The new invention has not been put into use. |
答案
小题1:B
小题2:C
小题3:C
小题4:B
解析
小题1:整篇文章介绍了一种新发明——利用生活垃圾生产沼气。
小题2:从第一段第三句可以看出,仅欧洲本身的垃圾每年就能生产出94亿立方米的沼气,但
只有1%得到利用,其余全部烧毁以防气体爆炸。
小题3:根据前面的“管道让氧气渗入”判断that指的是“氧气”。
小题4:从倒数第二段可知,当沼气通过中井被吸出来后,来自中间层的二氧化碳会取而代之,而非氧气。

However, you will find college life is different from your previous school environment. Many of us can be easily overwhelmed by the details of running a well-balanced life. While some of us may have the know-how, I guess there are more of us who can benefit from learning about the experiences of others who have walked the college halls before you.
The following you may find of use about life on campus:
·Plan well. There are so many new things to do at a new college or university. Give yourself time to make new friends and became familiar with the campus, but don’t forget why you are there. Give some time for social activities and manage your time wisely.
·If you don’t have a “system” for planning your time now (like a day timer a computer data book). get one. Most of all, don’t depend on your memory.
·Don’t miss the guidelines. The restrictions, rules and regulations of all kinds can usually be found in your student’s handbook. Consider them well-balanced food for thought. What dates are important? What pieces of paper need to be handed in? What can / can’t you do in your student residence(住处)? Who has the right for what? What do you need to complete to graduate?
·Write the word “STUDY” on the walls of our bedroom and bathroom, and maybe it will help to to write it on a piece of paper and stick it on the telephone, TV and the kitchen table. Consider this — you are paying thousands of dollars for your course. You pay every time you have to repeat or replace a course.
·Build your identity. This is the time for you to decide what to do and what not to do. Take as much time as you need to explore new ideas. Do not be afraid of the beyond. This is learning to make good choices.

In my family, it was always important to place blame when anything had happened.
“Who did this?” my mother would scream about a dirty kitchen.
“This is your entire fault, Katherine,” my father would insist when the cat got out or the dishwasher broke.
From the time we were little, my sister, brothers and I told to each other. We set a place for blame at the dinner table.
But the Whites didn’t worry about who had done what. They picked up the pieces and moved on with their lives. The beauty of this was driven home to me the summer Jane died.
In July, the Whites sisters and I decided to take a car trip from their home in Florida to New York. The two older sisters, Sarah and Jane, were college students, and the youngest, Amy, had recently turned sixteen. Proud of having a new drivers license, Amy was excited about practicing her driving on the trip. She showed off her license to everyone she met.
The big sisters shared the driving of Sarah’s new car during the first part of the trip, but when they reached less crowded areas, they let Amy take over. Somewhere in South Carolina, we pulled off the highway to eat. After lunch, Amy got behind the wheel. She came to a crossroads with a stop sign. Whether she was nervous or just didn’t see the sign no one would ever know, but Amy continued into the crossroads without stopping. The driver of a large truck, unable to stop in time, ran into our car.
Jane was killed immediately.
I was slightly injured. The most difficult thing that I had ever done was to call the Whites to tell them about the accident and that Jane had died. Painful as it was for me to lose a good friend, I knew that it was far worse for them to lose a child.
When Mr. and Mrs. White arrived at the hospital, they found their two daughters sharing a room. Sarah had a few cuts on the head; Amy’s leg was broken. They hugged us all and cried tears of sadness and of joy at seeing their daughters. They wiped away the girl’s tears and made a few jokes at Amy as she learned to use her crutches(拐杖).
To both of their daughters, and especially to Amy, over and over they simply said, “We are so glad that you are alive.”
I was astonished. No blame. No accusations.
Later, I asked the Whites why they never talked about the fact that Amy was driving and had run a stop sign.
Mrs. White said, “Jane is gone, and we miss her terribly. Nothing we say or do will bring her back. But Amy has her whole life ahead of her. How can she lead a full and happy life if she feels we blame her for her sister’s death?”
They were right. Amy graduated from the University of California and got married several years ago. She works as a teacher of learning-disabled students. She’s also a mother of two little girls of her own, the oldest named Jane.

A.The author’s parents were less caring. | B.The author’s parents were less loving. |
C.The author’s parents were less friendly | D.The author’s parents were less understanding |

Green building means “reducing the impact(影响)of the building on the land”, Taryn Holowka of the US Green Building Council in Washington.D.C. said. According to Holowka, buildings account for 65 percent of total US electricity use.
But green buildings can reduce energy and water use. Also, the buildings are often located near public transportation such as buses and subways, so that people can drive their cars less. That could be good for the environment, because cars use lots of gas and give off pollution. Green buildings are often built on developed land, so that the buildings don’t destroy forests.
Marty Dettling is project manager for a building that put these ideas into action. The Solaire has been called the country’s first green high-rise building. According to Dettling, “We’ve reduced our energy use by one-third and our water by 50 percent.”
The Solaire cuts energy in part by using solar power. “On the surface of the building we have solar panels(电池板)which change the sun’s energy into electricity,” Dettling explained.
The Solaire also has lights that automatically turn off when people leave the room. In addition, the building has lots of windows, allowing people to use the sun for light during the day. The Solaire cuts water by reusing it.
Not everyone is eager to move into a green building, however. Some people think that things like solar panels cost more money than more traditional energy source. Anyhow, Holowka said, “It is going to take off.”
小题1: “A green building”most refers to a____________ building according to the passage.
A.not ripe or modern | B.covering green color |

C.people can collect energy from sunsight to heat water and produce electricity |
D.they are equipped with lots of modern but cheaper equipment |
A.the places will cause a lot of trouble and inconvenience to consruction work |
B.cars will give off more pollution and more forests will be destroyed |
C.the environment of the places is not better than that of big cities |
D.the places are poorly equipped and unfriendly. |
A.will become successful and popular very quickly |
B.will be begining to disappear |
C.will be more modern. |
D.will replace traditional buildings. |
A.Dettling designed the first green building in the US. |
B.Energy shortage calls for buildings of new design |
C.The Solaire serves as a model of high buildings. |
D.Green buildings help save environment. |
Sometimes you’ll hear people say that you can’t love others until you love yourself. Sometimes you’ll hear people say that you can’t expect someone else to love you until you love yourself. Either way, you’ve got to love yourself first and this can be tricky. Sure we all know that we’re the apple of our parents’ eyes, and that our Grandmas think we’re great talents and our Uncle Roberts think that we will go to the Olympics. but sometimes it’s a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge. it is time you build a positive self-image and learn to love yourself.
Self-image is your own mind’s picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about US. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.
The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list if you need to, but write down all of the great things you do every day. Don’t allow doubts to occur in it.
It very well might be that you are experiencing a negative self-image because you can’t move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you’re silly because you aren’t good at math, find a tutor. If you think you’re weak because you can’t run a mile, get to the track and practice. If you think you’re dull because you don’t wear the latest trends, buy a few new clothes. But remember, just because you think it doesn’t mean it’s true.
The best way to get rid of a negative serf-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat(拍) yourself on the back, you’ll know you’re well on your way. Good luck!
小题1:You need to build a positive self-image when you _________.
A.dare to challenge yourself | B.feel it hard to change yourself |
C.are unconfident about yourself | D.have a high opinion of yourself |
A.have positive effects | B.are probably untrue |

A.How to prepare for your success. | B.How to face challenges in your life. |
C.How to build a positive self-image. | D.How to develop your good qualities. |

The first few days are given to physical conditioning and to the teaching of basic skills such as first aid, map and compass reading, rope climbing, and other similar activities.
During the second part of the course students learn how to climb rocks and cliffs, how to use canoes and rafts in swift water, and in some schools how to sail, ski, climb mountains, and make long-distance hikes.
The first two parts of the course are done in groups. Members work together and help each other to overcome the increasing number of challenges. In the third part of the course, students are sent out alone for three days to survive in the wilderness with only a few necessities.
Who are the students of Outward Bound? They are both young people and adults, men and women. The minimum age is 16.5 years. There is no maximum age. About one-third of the 6,000 persons completing the course each year are women. Businessmen, housewives, university students, professors, doctors, and lawyers are among those taking part in the course.
In recent years special courses for the busy business managers have gained in popularity. These courses last from five to ten days rather than the usual three to four weeks of the normal course.
Not all students complete the Outward Bound course. In some cases the individual cannot meet the physical challenges. In its own words Outward Bound literature says: "Make no mistake, Outward Bound is not for everybody. The courses aren"t easy and are not meant to be."
Most students who finish the course share a common experience. They are surprised at themselves that they finish the course and they feel great pride in doing the impossible! The Outward Bound experience makes them feel that they are better than they know!
