rushing into producing biofuels (生物燃料 ) as a solution for global warming, saying that it could be harmful if
they do not consider the long-term influence of what they are doing carefully.
It is necessary to build standards for the supply system of any green fuel project in order to make sure that
there aren"t any side effects on the environment and social structures. The report produced by the scientists
expresses concem that many companies may not be fully aware of the possible disadvantages.
Production of crops (农作物) , such as com and soya beans, has increased greatly in the last few years as
another eco-friendly choice to natural fuels, but environmental and human rights movement leaders are worried
that this will lead to destruction (破坏) of rain forests. Food prices could also go up as there is increasing
competition for crops as both food and sources of fuels. Last week, the UN wamed that biofuels could have
dangerous side effects and said that steps need to be taken to make sure that land chosen to grow biofuels
does not damage the environment or social structures. There is already great concem about palm oil (棕榈油) , which is used in many foods in addition to being an important biofuel, as rain forests are being cleared in
some countries and people driven from their homes to plant more palms.
The report suggests that biofuels are not a solution for climate change but they can play their ptut as long
as govemments and companies manage the social and environment influence thoroughly. There should also be
greater measures (措施) taken to increase the effectiveness and to reduce needs.
B．unwanted results
C. increasing influences
D. unchanged advantages
B. the waming given by the UN
C. the green biofuels liked by people
D. the possible disadvantages of biofuels
B. Greater measures should be taken to reduce the amount of biofuels.
C. Almost all the companies are worried about the future of biofuels.
D. Rain forests are being cleared to grow more palms as biofuels.

There are two ways to make 3D glasses. You can decide which way would be easier for you.
The first way seems like the cheaper way but the things needed to make the glasses this way may not be
things laying around the house. First print out a template(模板) for the glasses at
http://paperproject. org/ PDF files/3 dglasses. pdf.
After you cut out the template, cut your cellophane (玻璃纸) to fit the holes in the glasses. Make sure you
place the red cellophane on the left eye and the blue on the right. You can either stick or tape the cellophane in
place. You are now ready to use your glasses.
To leam more about why your eyes see different colors, read this article:

To learn some more cool things about your eyes, check out the games at this link:
http_://faculty. washington. edu/chudler/chvision. html.
Another way you can make 3D glasses is to find an old pair of sunglasses. Take out the lenses(镜片).
Get a piece of clear plastic and place the lenses on it, draw a line around the lens and then cut the new
plastic lens out. Place the lens back into the sunglasses frame (框). Color the left lens red with a marker
and the right eye blue. You now are ready to watch 3D films.
B. When we cook dinner.
C. When we make things.
D. When we see some films.

B. Hard.
C. Interesting.
D. Boring.
parents often send their children to the best schools or even abroad to England, the United States or Australia.
They also want their children to take extra- course (额外课程) activities where they will either leam music or
dance,or other classes that will give them a head start in life. The Chinese believe that the more expensive an
education is, the better it is. So parents will spend an unreasonable amount of money on education. Even poor
couples will buy a computer for their son or daughter.
However, what most parents fail to see is that the best early education they can give their children is usually
very cheap. Parents can see that their children"s skills are different, maybe skilled in some areas while poor in
others. What most parents fail to realize though, is that today"s children are in need of self-respect and
self-confidence. The problem is that parents are only educating their children on how to take tests and how to
study well, but parents are not teaching them the most important skills they need to be confident, happy and
clever.
Parents can achieve this by teaching practical skills like cooking, sewing and doing other housework.
Teaching a child to cook will improve many of the skills that he will need later in life. Cooking requires
patience and time. It is an enjoyable but difficult experience. A good cook always tries to improve his cooking,
so he will leam to work hard and gradually finish his job successfully. His result, a well-cooked dinner, will give
him much satisfaction and a lot of self-confidence.
Some old machines, such as a broken radio or TV set that you give your child to play with will make him
curious (好奇的) and have interest. He will spend hours looking at them, trying to fix them; your child might
become an engineer when he grows up. These activities are not only teaching a child to read a book, but rather
to think, to use his mind. And that is more important.
B. when children should be educated
C. what children really need in later life
D. why school tests don"t satisfy children
B. Interest is necessary for everything.
C. Broken things are useful for children.
D. Using hands helps improve thinking ability.
B. children today should leam different skills
C. practical skills are helpful to children"s growth
D. school education can"t meet parents" expectations
of hundred dollars may be enough. The training centre opened its doors last year, and, since then, men and
women of all ages have been paying A $ 200 an hour for lessons on how to feel great. "You can really increase
your happiness levels. That"s what we teach, " said Timothy Sharp, beginner of the centre.
Experts say that only about 15 per cent of happiness comes from income and finance(收入及财务). As
much as 85 per cent comes from things such as attitude, life control and relationships.
Most of us are better off financially than our parents and grandparents, but happiness levels haven"t
changed to match that.
Studies show that once the basic needs of housing and food are met, other wealth adds very little to
happiness.
Scientists now say part of the reason we are richer but not happier is that we compare ourselves to
people better off. "
The fact is that if you want to be happy, there"s a very simple thing you can do: compare yourself to
people who are less well off than you-poorer, smaller house, etc. ," said Sharp.
The Happiness Training Centre hopes to show you how to overcome these unhappiness factors(因素) by
paying attention to" more than just your bank account".
"If I compare myself to Bill Gates, then I"m always going to be down," said Sharp.

and also reviewed the scientific research works on that. Among all the methods, three should be specially
mentioned: they"re useful, simple and easy to leam. What"s more, people who have made successful changes in
their lives often depended on one or more of these methods.
To get yourself started in a new direction, try the Three M"s:
Modify Your Environment. People who have never tried this are surprised by the large result it often had.
One of my students got herself bicycling every day simply by putting her bicycle in her doorway before she
left for schools. When she retumed home, that was the first thing she saw, and that"s all she needed to start
cycling away. The power of rearranging (重新布置) one"s space has been well shown in studies since it was
first reported in the 1960s. Professor Israel Goldiamond taught this method to patients with different personal
problems. For example, a young woman who had difficulty studying made great improvement when she got a
better desk lamp and moved her desk away from her bed. To change yourself, change your world.
Monitor Your Behavior. I"ve been reading research studies on self-monitoring for 20 years, and I"ve tried
some myself. To be honest, I still don"t fully understand why this method works, but it does, and surprisingly
well for most people. The fact is, if you monitor what you do, you"ll probably do better. Weigh yourself often
and you may well start to lose weight. Keep a record of what you eat and you"ll probably start eating more
wisely. Use tiny objects. If you say "you know" too much, take a golf counter, and push down the counter
whenever you catch yourself saying "you know". I"ll be sure you say it less often in just a few days. Or you
can put a small piece of paper in your pocket each time you say "you know". The result is the same: you
become more sensible about what you"re doing, and that makes you do better.
Make Promises. When you make a promise to another person, you"ve arranged for a reward(奖赏) if you
keep it and a punishment if you don"t.lt puts some pressure (压力) on you, and that"s often just what you need.
For example, if you want to exercise more, arrange to do it with a friend. If you don"t, your friend will get
angry, and that may be just the ticket to keeping you on time.
B.Improve.
C.Create.
D.Arrange.
B.To present some successful changes.
C.To show the study results of self-change methods.
D.To encourage people to change their bad habits.
B.Keep a record of what you"ve achieved.
C.List the hours spent on computer games.
D.Talk with your friends about your pressure.
Almost certainly, a machine can do any work in thinking that a person can do-if the correct way for doing
the thinking work can be told exactly. Besides, many programs have been made to direct machines so that
they work in very clever ways. Machines have been taught to play chess and to leam from what happens in
the games so as to make their play better and better. Machines can beat many persons who play chess.
Machines can translate from one language to another. They can prove statements in geometry (几何) as
taught in school. Machines can notice printed marks on paper, so that a person is no longer needed to look
at the marks.
Computers can be used in many ways, such as business, science, industry, and govemment. Computers
study oil-field examinations made by airplanes; they keep record of oil sales; they study the working condition
of the machines; they help in plan- ning and producing oil; and much more. If people cannot tell exactly the
correct way to do certain work in thinking, it is still a question how much of this work a machine can do.
Suppose a person is "teaching" the machine and telling the machine "yes" when the machine is right, and "no"
when the machine is wrong. Then the machine can keep on searching among possible ways for solving
a problem-until the machine can do as well as the person, and per haps much better.
But, what is thinking? People can agree about much that is thinking, and much that is not thinking; but they
can"t reach agreement because the word "think" is not a scientific word with an exact meaning. A lot of the
discussion is wasted breath because the persons are using different meanings of the word "think".
People, however, have only had experience with machines that appear to think since 1944.
It would be too early to say that after the next 200 years, machines will not be thinking. And to consider
that machines can think gives people a big push to give to machines more and more work in thinking.
B. Govemment.
C. Sports.
D. Industry.
B. Teaching.
C. Searching.
D. Telling.
B. People discuss a lot about thinking.
C. There is no answer to what thinking is.
D. People already know what thinking is.
B. A machine can do better translation than human beings.
C. A machine won"t be able to beat every chess player.
D. A machine will be able to make plan programs.
B. Can Machines Think?
C. Can Machines Be Taught to Think?
D. Can Machines Beat All Checkers Players?
