Space is where our future is — trips to the Moon, Mars and beyond. Most people would think that aside from comets(彗星) and stars, there is little else out there. But, since our space journey started we have left so much trash（垃圾） there that scientists are now concerned that if we don't clean it up, we may all be in mortal （致命的）danger.
The first piece of space junk was created in 1964, when the American satellite Vanguard I stopped operating and lost its connection with the ground center. However, since it kept orbiting around the Earth without any consequences, scientists became increasingly comfortable abandoning（抛弃） things that no longer served any useful purpose in space.
It is estimated （估计）that there are now over 500,000 pieces of man-made trash orbiting the Earth at speeds of up to 17,500 miles per hour. The junk varies from tiny pieces of paint chipped off rockets to cameras, huge fuel tanks, and even odd items like the million-dollar tool kit that astronaut Heidemarie Stefanyshyn Piper lost during a spacewalk.
The major problem with the space trash is that it may hit working satellites and damage traveling spacecraft(飞船). Moreover, pieces of junk may collide（碰撞） with each other and break into pieces which fall back to the Earth. To avoid this, scientists have invented several ways for clearing the sky. Ground stations have been built to monitor larger pieces of space trash to prevent them from crashing into working satellites or space shuttles. Future plans include a cooperative effort among many nations to stop littering in space and to clean up the trash already there.What was the first piece of man-made space trash?

My father never wanted his children to know what he did for a living. Dad worked in Plant C. Lying beside Lake Erie, it saw him in at sunrise and out at nightfall. Sometimes my mother would take my siblings (兄弟姐妹) and me to the public beach in our hometown of Ashtabula. She’d gather us round and point to the smokestacks, coughing clouds into the sky.
“Wave to daddy!” she’d shout. Four little hands would shoot into the air. I never knew what Dad did in Plant C, but during 34 years of hard work, he had surgery (手术) on his shoulder and hand. At 48, he had his first heart attack. He retired in 1993, right after the last kid graduated from college. But the damage was done. A few years later, the next heart attack killed him.
I saw my dad in plant C only once, when I took dinner to him. That night, I looked at my father, covered in sweat and coal, and for the first time I knew why he was so often angry for no reason.
Recently my father’s friend, Toby Workman, walked me there. I knew my father never wanted me to see it. At every station, he described the job and the danger. It was like listening to a foreign language. I walked past many DANGER signs. Toby put his hand on my shoulder. “Look”, he said, “you need to understand something. Your dad was a maintenance mechanic. He worked the most dangerous job. If something broke, he fixed it. ”

Do you find getting up in the morning so difficult that it’s painful? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.
During the hours when you labor through your work you may say that you’re "hot". That's true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people the peak comes during the morning. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues as “Get up, John! You’ll be late for work again!” The possible explanation to the trouble is that John is at his temperature-and-energy-peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles each member of the family has.
You can’t change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes. Maybe you’re sleepy in the evening but you must stay up late anyway. Counteract your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour. This won't change your cycle, but you'll get up steam and work better at your low point.
Get off to a slow start which saves your energy. Get up with a leisurely yawn and stretch. Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the trouble of searching for clean clothes by laying them out the night before. When ever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharp hours.What is the best title of the passage?
| A．Change Your Habits | B．Save Your Energy |
| C．Daily Energy Cycle | D．Temperature-and-energy Peak |
If a person finds getting up early a problem, most probably_______.
| A．he is a lazy person |
| B．he refuses to follow his own energy cycle |

| A．Unawareness of energy cycles |
| B．Familiar monologues. |
| C．A change in a family member's energy cycle. |
| D．Attempts to control the energy cycle of other family members. |
If one wants to work more efficiently at his low point in the morning, he should____________.

If you want to get the most out of the study of a language, you must also read for pleasure: novels, plays, travel books, and so on. And in reading books of this kind the important thing is to get on with the reading; to try to grasp what the writer is going to tell you in the book as a whole. This is impossible if you stop and think over the meaning of every single word which happens to be unfamiliar. You can not enjoy a story if you stop half a dozen times on every page in order to look up words in the dictionary. You may even prevent yourself from understanding the story as a whole by doing this.
When you are reading books of this kind, therefore, you will usually have to rely mainly on the context to help you. If you meet an unfamiliar word, do not let it take too much of your attention from the main thread(主线) of the story. In all probability you will meet the same word again a few pages later on in a slightly different context, and each time you see it that your understanding of it will become more exact.The phrase “to get on with reading” in the passage has the same meaning as “_________”.
| A．to try to grasp the meaning of every sentence in the book |
| B．to try to catch the meaning of every word in the book |
| C．to try to understand all the writer is going to tell you |
| D．to try to understand the main idea of the book |

| A．stop and look them up in a dictionary | B．stop and think them over |
| C．try to guess their meanings from the context | D．have none of them |

The World Trade Organization (WTO) founded on January 1, 1994, aims to encourage international trade to flow as freely as possible, making sure that trade agreements are respected and that any disputes (争端) can be settled.
In the five years since its founding, the WTO has become well-known as one of the world’s most powerful economic organizations, taking its place alongside the World Bank and International Monetary Fund.
The system of global rules for international trade, however, dates back half a century to 1948 when the General Agreement on Tariffs (关税) and Trade (GATT) was formed after World War II.
As time went by it became clear that the GATT had two major drawbacks—the limited areas of trade it covered, and the lack of an effective system to settle disputes.
After seven years of trade talks ending in 1994. the so-called Uruguay Round finally gave birth to the WTO, complete with an effective system to settle disputes and new rules covering trade in services and intellectual property (知识产权).
Even after seven years of talks and 22500 pages of agreements there were still problems, especially the difficult-to-deal-with areas of agriculture and services.
The WTO. with its head office in Geneva, has 135 members with 30 more waiting to join.Compared with the GATT, the WTO _____.
| A．can do better to settle disputes in more areas of international trade |
| B．got its members to sign the agreements more easily |
| C．has got too many areas of international trade to deal with to work effectively |
| D．didn’t pay enough attention to services and intellectual property |
In the new century the WTO will _____.
| A．take the place of the World Bank and International Monetary Fund |
| B．have new rules covering trade in services and intellectual property |
| C．make complete new rules in every area of international trade |
| D．have more members and do much more to settle more problems |
The underlined word “drawbacks” probably means _____.
| A．weak points | B．changes | C．strong points | D．improvements |
The best title for the passage is _____.
| A．WTO—Another Name for GATT |
| B．WTO—an International Service Organization |
| C．WTO—One of the World’s Strongest Economic Organizations |
| D．WTO—the World’s Most Powerful Economic Organization |
