In the last stages of the disease, the patient may not be able to take care of himself. He may have lost the ability to speak and walk.

Scientists don't know exactly what causes Alzheimer's disease. It may be caused by a virus (病毒). It may be caused by a poisonous substance(物质) in the environment.

The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruits and green vegetables. It is only when people try to live on a very restricted diet, say that when trying to lose weight, that it is necessary to make special provisions to supply the missing vitamins.
  An example of the dangers of a restricted diet may be seen in the disease known as “beri-beri”, which used to make large numbers of Eastern people who lived mainly on rice suffer. In the early years of last century, a Dutch scientist named Eijkman was trying to discover the cause of beri-beri. At first he thought it was transmitted(传播)by a germ(病菌). He was working in a Japanese hospital, where the patients were fed on polished rice which had had the outer coverings removed from the grain. It was thought this would be easier for weak and sick people to digest.
  Eijkman thought his germ theory was proved when he noticed the chickens in the hospital yard, which were fed on remains from the patients’ plates, were also showing signs of the disease. He then tried to separate the germ, which he thought was causing the disease, but his experiments were interrupted by a hospital official, who ordered that the rice without coverings, even though left over by the patients, was too good for chickens. It should be recooked for the patients, and the chickens should be fed on cheap, rough rice with the outer coverings still on the grain.
  Eijkman noticed that the chickens began to recover on the new diet. He began to consider the possibility that eating unmilled rice(糙米)somehow prevented or cured beri-beri — even that a lack of some ingredient(成分)in the coverings may be the cause of the disease. Indeed this was the case. The element needed to prevent beri-beri was shortly afterwards separated from rice coverings and is now known as vitamin B. The milled rice, though more expensive, was in fact causing the disease the hospital was trying to cure. Nowadays, this terrible disease is much less common thanks to our knowledge of vitamins.
【小题1】According to the passage, a good mixed diet ________.

【小题2】What do we know about the disease beri-beri?

C.It was transmitted by milled rice.D.It was caused by diseased chickens.
【小题3】What can be the best title of the passage?
A.A Good Mixed Diet       B.New Discovery
C.The Dangers of Beri-beri     D.The Importance of Vitamins

It's not a new phenomenon, but have you noticed how many nouns are being used as verbs? We all use them, often without noticing what we're doing.

I was arranging to meet someone for dinner last week, and I said “I’ll pencil it in my diary”, and my friend said “You can ink it in”, meaning that it was a firm arrangement not a tentative one!

Many of these new verbs are linked to new technology. An obvious example is the word fax, which is a shortening of facsimile originally, an exact copy of a book or document. We all got used to sending and receiving faxes, and then soon started talking about faxing something and promising we'd fax it immediately. So, nouns turn into verbs in two easy stages. Then along came email, and we were soon all emailing each other madly. How did we do without it? I can hardly imagine life without my daily emails.

Email reminds me, of course, of my computer and its software, which has produced another couple of new verbs. On my computer I can bookmark those pages from the World Wide Web that I think I'll want to look at again, thus saving all the effort of remembering their addresses and calling them up from scratch. I can do the same thing on my PC, but there I don't bookmark; I favorite—coming from “favorite pages”, so the verb is derived from an adjective not a noun. I wasn’t really sure whether people said this, but someone told me recently that they had favorited a site I was looking for and so they could easily give me its address.

In the late 1980s I noticed that lots of my friends had acquired pagers, and kept saying things like “I’ll page you as soon as I know what time we’re meeting”. They couldn't say it to me, though; I refused to have one. So my children bought me a mobile phone, now known simply as a mobile and I had to learn yet more new verbs. I can message someone, that is, I can leave a message (either spoken or written)for them on their phone.Or I can text them, write a few words suggesting when and where to meet, for example. How long will it be before I can mobile them, that is, phone them using my mobile? I haven’t heard that verb yet, but I’m sure I will soon. Perhaps I’ll start using it myself!  

60. “I’ll pencil it in my diary” in the second paragraph probably means              .

A. it was a firm arrangement            

B. it was an uncertain arrangement

C. the arrangement should be written as a diary    

D. he prefers a pencil to a pen

61. A website address can be easily found if it has been            .

A. emailed            B. messaged          C. favorited          D. texted

62. Which of the following has not been used as a verb yet?

A. message            B. page                 C. email               D. mobile

63. The best title for this passage is           .

A. New Verbs from Old Nouns    

B. The Development of the English language

C. New Technology and New words     

D. Technology and Language

For years scientists have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse.

Indoor air pollution can cause a person to feel tired, to suffer eye pain, headache and other problems. Some pollutants can cause breathing disorders, diseases of blood and even cancer. Most scientists agree that every modern house has some kind of indoor pollution.

People have paid more attention to the problem now. It is true that when builders began making houses and offices they did not waste energy. To do this they build buildings that limited the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to let out harmful gases.

As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building—green plants. Scientists do not really know how plants control air pollution. They believe that a plant’s leaves absorb or take in the pollutants. In exchange the plant lets out oxygen through its leaves and tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and more healthy place.

1.Generally speaking, indoor air pollution may be more harmful than the air outside because ______.

A.indoor air pollution can often make people seriously ill

B.man-made building materials give off dangerous gases

C.there may be more harmful gases outside the buildings

D.the air indoors is polluted, which is very harmful

2.Some kind of indoor pollution can be found in______.

A.every modern house          B.every old house

C.all kinds of houses           D.all kinds of offices

3.The indoor air pollution is caused by ______.

A.the limit of the flow of air between inside and outside

B.the building way that the builders want to save energy

C.the building things that are made of man-made materials

D.the man-made building materials and the limit of air-flow

4.The reason why we should use different kinds of plants to clean the air is that ______.

A.plants can let out all kinds of pollutants indoors

B.plants may take in more oxygen which people need

C.plants can absorb all kinds of harmful indoor chemicals

D.plants can make our houses prettier and more healthy
