A good memory is a great help in learning a language. Everybody learns his own language by remembering what he hears when he is a small child, and some children, like boys and girls who live abroad with their parents, seem to learn two languages almost as easily as one. In school it is not easy to learn a second language because the pupils have so little time for it, and they are busy with other subjects, too.

A man’s mind is rather like a camera, but it takes photos not only of what we see but of what we feel, hear, smell and taste. When we take a real photo with a camera, there is much to do before the photo is finished and ready to show to our friends. In the same way there is much work to be done before we can keep a picture forever in our mind.

Memory is the diary that we all carry about with us.

Sam, a dog, was left behind in Colorado while his owners, Mr. And Mrs. Green moved to Southern California. They did not give the dog up. They found him a very nice home before they moved. They would have let Sam accompany them, but they were afraid the dog’s presence would make it difficult for them to rent a house when they reached their destination.

The Green family lived in Colorado for less than a year. Before that, they had lived in the same neighborhood in California to which they returned. So Sam had been there before, but only for a short time when he was young.

Several months after the Greens left Colorado, after they were comfortably settled back in California, they heard a scratch at the door. They couldn’t imagine who might be there. It nev

might be Sam, because they were sure he was happily set up with his new family back in Colorado.

When they opened the door, the Greens saw a dirty, tired dog with very hurting feet. The animal looked a little bit like Sam, but no one could believe that Sam could have walked 840 miles on his own. The tired dog spent the night under the family car. The next day, when he was more rested, he performed some of his old tricks. The Greens knew they had their own dog back.

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 (污染物) 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 said that when builders began making houses and offices they did not waste energy. To do this they built 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 (吸收) or take in the pollutants. In exchange the plant lets out oxygen through its leaves and small organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square metres 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.

64. 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

there may be more harmful gases outside the buildings

D.     the flow of air indoors is limited, which is very harmful

65. 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

66. 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

67. 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

New York: When the first plane struck 1 World Trade Center at 8:48 am on Tuesday, the people in 2 World Trade Center who saw the instant (瞬间的) damage to the other tower realized clearly what they, too, must do: get out fast.

Katherine Ilachinsiki, who had been knocked off her chair by the blast (一阵)of heat exploding from the neighboring tower, was one of those. Despite her 70 years of age, Mrs Ilachinsiki, an architect working on the 91st floor of 2 World Trade Center, the south tower, went for the stairs. Twelve floors above her, Judy Wein, an executive (经理), cried sharply and set off too.

But others up and down the 110 floors, many without seeing the damage across the way and thus unclear about what was happening, were not so sure. And the 18 minutes before the next plane would hit were ticking off.

Most people had no idea about what was the best thing to do, formal announcements inside the south tower asked people to stay put, assuring (使……确信) them that the building was sound and the threat (威胁)was limited to the other tower.

Some left, others stayed. Some began to climb down and, when met with more announcements and other cautions (警告) to stop or return, went back up. The decisions made in those instants proved to be of great importance, because many who chose to stay were killed completely when the second plane crashed (坠落，碰撞) into the south tower.

One of those caught in indecision (犹豫不决) was the executive at Fuji Bank USA.

Richard Jacobs of Fuji Bank left the 79th floor with the other office workers, but on the 48th floor they heard the announcement that the situation was under control. Several got in the lifts and went back up, two minutes or so before the plane crashed into their floor.

“I just don’t know what happened to them,” Mr Jacobs said.

68. From the passage, we know that the south tower was hit by the plane ________.

A. at 8:30                                                        B. 18 minutes earlier than the north tower

C. at around 9:06                                              D. at 8:48

69. The underlined words “stay put” means ________.

A. stay in the building                                       B. leave at once

C. put everything back and then leave                 D. keep silent

70. Which floor was hit by the second plane?

A. The 91st floor           B. The 103rd floor          C. The 60th floor    D. The 79th floor

71. Fewer people would have died if ________.
