Mobile phone companies are worried about the negative publicity of such ideas. ___【2】___

On the other hand, why do some medical studies show changes in the brain cells of some people who use mobile phones?

【題目】Modern inventions have speeded up people’s loves amazingly. Motor-cars cover a hundred miles in little more than an hour, aircraft cross the world inside a day, while computers operate at lightning speed. Indeed, this love of speed seems never-ending. Every year motor-cars are produced which go even faster and each new computer boats (吹噓) of saving precious seconds in handling tasks.

All this saves time, but at a price. When we lose or gain half a day in speeding across the world in an airplane, our bodies tell us so. We get the uncomfortable feeling known as jet-lag; our bodies feel that they have been left behind on another time zone. Again, spending too long at computers results in painful wrists and fingers. Mobile phones also have their dangers, according to some scientist; too much use may transmit harmful radiation into our brains, a consequence we do not like to think about.

However, what do we do with the time we have saved? Certainly not relax, or so it seems. We are so accustomed constant activity that we find it difficult to sit and do nothing or even just one thing at a time. Perhaps the days are long gone when we might listen quietly to a story on the radio, letting imagination take us into another world.

There was a time when some people’s lives were devoted simply to the cultivation of the land or the care of cattle. No multi-tasking there; their lives went on at a much gentler pace, and in a familiar pattern. There is much that we might envy about a way of life like this. Yet before we do so, we must think of the hard tasks our ancestor faced: they farmed with bare hands, often lived close to hunger, and had to fashion tools from wood and stone. Modern machinery has freed people from that primitive existence.

【1】The new products become more and more time-saving because .

A. our love of speed seems never-ending

B. time is limited.

C. the prices are increasingly high.

D. the manufactures boast a lot.

【2】What does “the days” in Paragraph 3 refer to ?

A. Imaginary life

B. Simple life in the past.

C. Times of inventions

D. Time for constant activity.

【3】What is the author’s attitude towards the modern technology?

A.Critical B.Objective.

C.Optimistic. D. Negative.

【4】What does the passage mainly discuss?

A. The present and past times.

B. Machinery and human beings.

C. Imaginations and inventions.

D. Modern technology and its influence.

If you do not use your arms or your legs for some time，they become weak；when you start using them again，they slowly become strong again．Everybody knows this, and nobody would think of questioning the fact. 【1】 When someone says that he has a good memory，he really means that he keeps his memory in practice by exercising it regularly, either consciously or unconsciously．When someone else says that his memory is poor，he really means that he does not give it enough opportunity to become strong． 【2】 One of them exercises his arms and legs by playing tennis, while the other sits in a chair or a motor car all day.

If a friend complains that his arms are weak, we know that it is his own fault. 【3】 , many of us think that his parents are to blame，or that he is just unlucky, and few of us realize that it is just as much his own fault as if it was his arms or legs that were weak．Not all of us can become extremely clever; but all of us can, if we have ordinary bodies and brains, improve our strength and our memory by the same means—practice.

Have you ever found that some people who cannot read or write usually have better memories than those who can? 【4】 Of course, because those who cannot read or write have to remember things；they cannot write them down in a little notebook．They have to remember dates，time and prices, names，songs and stories；so their memory is the whole tme being exercised．

【5】 ，learn from the poor：practise remembering．

A. What do you think of it?

B. Yet many people do not seem to know that memory works in the same way．

C. But if he tells us that he has a poor memory

D. So if you want a good memory

E. When someone else says that he is poor in the health

F. Why is this?

G. The position is exactly the same as that of two people.
