Passage 1
Narcolepsy is a neurological disorder whose main symptom is excessive,
overriding sleepiness. A victim can fall asleep anytime, anywhere, even in the most circumstances. And there is no cure. “Having narcolepsy,” says Bill, “is like always being as sleepy as a normal person might be after staying awake three days.” It is estimated that a quarter million Americans have narcolepsy, mostly undiagnosed. This is because, in a physical exam,a doctor may not find anything wrong with a narcoleptic person. It may take years, and visits to several doctors, before a narcoleptic discovers the name of his problem. Researchers now believe that the disease is triggered by a chemical imbalance in the part of the brain that controls wakefulness. Initial symptoms may also include a sudden loss if muscle tone brought on by an intense emotion--anything from anger to laughter. Some narcoleptics hallucinate or develop sleep paralysis, which is the feeling during the lighter stages of sleep of being completely unable to move or talk. The prognosis for a patient with narcolepsy isn’t good. Narcoleptics have the disease all their lives, and many cannot hold down a job or lead a normal life. Some narcoleptics take daily doses of prescribed drugs like Dexedrine --”uppers”--to stay awake lone enough to function. The problem of narcolepsy is being studied now, and someday there may be a cure. But current sufferers must endure an existence, that is, as one woman said, “like walking through glue.”

Passage 2
There’s no doubt that nanotechnology promises so much for civilization. However, all new technologies have their teething problems, And with nanotechnology, society often gets the wrong idea about its capabilities. Numerous science-fiction books and movies have raised people’s fears about nanotechnology ---with scenarios such as inserting little nano-robots into your body that monitor everything you do without you realizing it,or self-replicating nano-robots that eventually take over the world.
So how do we safeguard such a potentially powerful technology? Some scientists recommend that nano-particles be treated as new chemicals with separate safety tests and clear labelling. They believe that greater care should also be taken with nano-particles in laboratories and factories. Others have called for a withdrawal of new nano products such as cosmetics and a temporary halt to many kinds of nanotech research.
But as far as I’m concerned there’s a need to plough ahead with the discoveries and applications of nanotechnology.I really believe that most scientists would welcome a way to guard against unethical uses of such technology. We can’t go around thinking that all innovation is bad.all advancement is bad. As with the debate about any new technology.it is how you use it that’s important.So let’s look at some of its possible uses.
Thanks to nanotechnology, there could be a major breakthrough in the field of transportation with the production of more durable metals. These could be virtually unbreakable, lighter and much more pliable leading to planes that are 50 times lighter than at present. Those same improved capabilities will dramatically reduce
the cost of traveling into space making it more accessible to ordinary people and opening up a totally new holiday destination.
In terms of technology, the computer industry will be able to shrink computer parts down to minute sizes. We need nanotechnology in order to create a new generation of computers that will work even faster and will have a million times more memory but will be about the size of a sugar cube. Nanotechnology could also revolutionise the way that we generate power .The cost of solar cells will be drastically reduced so harnessing this energy will be far more economical than at present.
56.In this passage the author tells us that one problem with nanotech is that .
A.it could threaten our way of life
B.It is misunderstood by the public
C.It could be used to spy on people
We only see nanotechology in some books and movies
57.The author says that some scientists believe that nano-particles____.
A.should be used with more caution
B.Should be restricted to secure environments
C.Should only be developed for essential products
D.Should halt to do many kinds nanotech research
58.In the author’s opinion, research into nanotechnology probably means that it_.
A.has yet to win popular support B.ought to be continued
B.C.could be seen as unethical D.can replicate people completely
59.It can be deduced from the passage that___.
A.the use of Nanotcech could eventually take over the world
B.Nanotech has few implications affecting us in many ways
C.it is too expensive to make solar energy
D.it is possible users are very helpful and beneficial to humans.
60.The underlined word”pliable”(line, Para.4) can be replaced by_.
A.durable B.straight C.bent D.unbreakable
