Biomass energy (生物能).often forgotten as a promising alternative (替代物) to oil, received its day in the sun with the gathering of the Bio-Energy World Congress and Exposition in Atlanta, Georgia, late in April, 1990. Nearly 1, 700 scien??tists, businessmen, and policy-makers, one-quarter from the foreign nations, gathered for a week to discuss various means of squeezing usable energy out of trees, crops, manure, sea??weed, algae, and urban waste. Biomass in the United States contributes 2. 5 percent of the total supply, but this amount can be doubled by 2000 and then doubled again by the year 2010.

Eight percent of Sweden’s energy supply, for example, is presently coming from wood bark and pulp remainings, Sweden intends to raise this percentage by more intensive harvesting of waste food lying around in forests, and through the planting of so-called energy forests of fast-growing trees such as willow and birch.

Brazil is frequently pointed to as a nation with a major successful investment (投资)in energy coming from grains: it presently runs 330,000 automobiles on a water and alcohol (酒精) mixture, replacing 10 percent of its previous oil sup??ply. Brazilian representatives (代表) at the conference said they wish to double this in five years, with a final goal of total replacement. Most of the cars are built at the factory to use the mixture, while older models are changed through low-cost gov??ernment programs.

China’s second manned（人造的） space flight will be done by two astronauts（宇航员） over five days in 2005. “Shenzhou-VI will be sent into space sometime in 2005,” said Zuo Saichun, a spokesperson of the China Aerospace Science and Technology (CAST). “The spacecraft（宇宙飞船） will make new breakthroughs（突破性进展） in China’s manned space technology.”

    Unlike Shenzhou-V, a little more than a year ago (in October, 2003), the next flight will see two astronauts fly in space for five days. Their capsule (太空舱) is designed to be capable（能够）of orbiting（绕轨道运行） for a whole week, the spokesperson said. “For the first time, astronauts will enter and live in the orbital module（舱） of the spacecraft to do scientific experiments,” said a statement from CAST. CAST did not say what those experiments will be.

    In Shenzhou-VI, scientists have changed the spacecraft’s configuration (构形) to reduce its weight, and tried to improve the performance of on-board equipment. They have also worked to make sure of the energy supply of the spacecraft and further improve its safety. So far, scientists have worked out ways to solve problems on environmental control and life support. Shenzhou-VI will be sent into orbit atop（在……顶上） a Long March 2F rocket.

    Meanwhile, a model of the Chang’e-1 satellite is expected to be sent to orbit the moon in two years. The satellite, part of the three-stage programme, would be followed by the landing of an unmanned vehicle on the moon in the second stage by 2010 and collecting samples（样品） of lunar soil by 2020 in the final stage, according to Sun Laiyan, director of the China National Space Administration.

　　   A. It will be sent into space in 2005.

　　   B. It is capable of orbiting for two weeks.

　　   C. It will be sent into orbit atop a Long March 2F rocket.

　　   D. It will be sent into space with two astronauts.

2.. According to the passage, the following problems should be solved before Shenzhou-VI is sent into space EXCEPT ______.

　　   A. environmental control     B. energy supply

　　   C. life support              D. lunar soil collecting

3.. Which of the following does NOT belong to the three-stage programme?

　　   A. Shenzhou-VI’s being sent into space.

　　   B. A model of the Chang’e-1 satellite will be sent to orbit the moon.

　　   C. The landing of an unmanned vehicle on the moon.

　　   D. Collecting samples of lunar soil.

4.. The passage mainly tells us ______.

　　   A. some problems need solving before Shenzhou-VI is sent into space

　　   B. Shenzhou-VI will be sent into space in 2005

　　   C. what China’s space programme is

　　   D. how China’s three-stage programme is carried out

完形填空(共10小题；每小题2分，满分20分)

The Americans are desperate, and with good reason, they have successfully kept the U.S. economy in__21__ after the financial crisis, but the problem is far from over. Despite a moderate recovery, the lack of job creation is serious. Many U.S. leaders rightly see jobs as the key to their country’s __22__and avoiding a second dip. The lack of a solution is fast becoming a political one as the November elections approach. Recent __23__ to get tough with China are gaining momentum（势头）in various quarters. The charge that China is the __24__of the U.S.-led financial crisis in the West looks ridiculous in the East. But we should at least give it a proper response.

The logic goes like __25__: China is the cause of America’s cheap money, and cheap money is the cause of the crisis. This is like saying a kid is corrupt(挥霍无度) __26__ he has a rich father who makes his wild spending possible; to cure the kid’s problem, you have to rein in（鞭笞）the father. This is not a very good parallel. But the United States is spending the money it borrowed from China.

There is a big gap between cheap money and wild spending on one side and irresponsible lending on __27__. You can pay down your mortgage faster and spend only what you have left, or you can take out a second mortgage to have an expensive vacation and buy a new S.U.V. Many Americans  __28__ the latter path. But who is __29__? The banks? Yes! But China?

The West must recognize that its problem — and its solution — come from within. What China did or did not do did not create the financial crisis. What China will do or not do would not solve their problems. But China can help and it is willing. And you are not going to get it by getting __30__ with China.

When we think about giving help to developing countries, we often think about giving money so that these countries can build schools and hospitals, buy food and medicine, or find clean water supplies. These seem to be the most important basic needs of the people we are trying to help. However, it’s far from enough. Ladies and gentlemen, we’ve got to come up with some better ideas to help them.
I was very surprised, then, when I read about a plan to make cheap laptop computers（便携式电脑）for children in developing countries. A man called Nicholas Negroponte invented a cheap laptop computer, which can run without electricity. He decided to invent this computer after he visited a school in Cambodia.
The laptop which Mr. Negroponte has designed is a little different from the normal laptop computers you can buy in the shops. One difference is that it will be covered in rubber so that it is very strong and won’t be damaged easily. As an electricity supply can be a problem in developing countries, the computer also has a special handle（把手）so that children can wind（摇）the computer up to give it extra power when needed.
These special laptop computers will cost less than 100 US dollars and Mr. Negroponte wants to build as many as 15 million machines in the first year of production. The idea is that these computers will help the children’s education as they will be able to access the Internet. These computers might not help the people in developing countries immediately, but by improving children’s education they should help people to find their own solutions to their problems in the long term.
Another idea to help children in developing countries is to recycle old mobile phones so that they can be used again. In the UK, and, probably in many other countries too, millions of mobile phones are thrown away every year. The waste created by throwing away these old phones is very bad for the environment, so it seems to be an excellent idea to recycle them. In this way we will be able to achieve two important goals（目标）at the same time. We will reduce the waste we produce and help others. In other words, we will be able to “kill two birds with one stone”, and that is always a good thing.
