I’m afraid to grow old—we’re all afraid. In fact, the fear of growing old is so great that every aged person is an insult and a threat to the society. They remind us of our own death, that our body won’t always remain smooth and responsive, but will someday betray(背叛) us by aging. The ideal way to age would be to grow slowly invisible, gradually disappearing, without causing worry or discomfort to the young. In some ways that does happen. Sitting in a small park across from a nursing home one day, I noticed that the young mothers and their children gathered on one side, and the old people from the home on the other.

Whenever a youngster would run over to the “wrong” side, chasing a ball or just trying to cover all the available space, the old people would lean forward and smile. But before any communication could be established, the mother would come over, murmuring embarrassed apologies, and take her child back to the “young” side.

Now, it seemed to me that the children didn’t feel any particular fear and the old people didn’t seem to be threatened by the children. The division of space was drawn by the mothers. And the mothers never looked at the old people who lined the other side of the park. These well-dressed young women had a way of sliding their eyes over, around, through the old people; they never looked at them directly. The old people may as well have been invisible; they offended the aesthetic eye of the mothers.

My early experiences were somewhat different; since I grew up in a small town, my children had more of a nineteenth-century flavor. I knew a lot of old people, and considered some of them friends.

Although similar in appearance to hyenas(土狼), African wild dogs are nevertheless true wild canine(犬). They are a mixture of black, yellow, and white in such a wide variety of patterns that no two individuals look exactly alike. African wild dogs are widely distributed across the African plains but they do not live in jungle areas.

They are social animals, living in groups of usually from 2 to 45 individuals. A hierarchy（统团） exists within the group, but the animals are friendly to one another. The young and the infirm（体弱的） are given special privileges within the group.

African wild dogs use their sense of sight, not smell, to find their prey. They can run up to 55 km/h for several kilometers. In eastern Africa, they mostly hunt Thomson's gazelles, but they will also attack calves, warthogs, zebras, impalas, and the young of large antelopes such as the gnu.

Growing human populations have decreased or degraded the African wild dog's habitat and also diminished their available prey. Road kill and human persecution（迫害） have also had a negative impact on African wild dog populations. This species is also susceptible to a variety of diseases such as distemper, which is controlled in domestic .dogs. Conservation of the African wild dog's natural habitat must have the highest priority, as these dogs suffer in habitats modified by human intrusion（干扰）．

1.What does the underlined word "susceptible" mean?

A. easily affected or suffered B. badly doubtful

C. seriously harmful D. highly dangerous

2.What factors affect the population of the wild dogs?

a. the distribution of the dogs b. social living

A. African wild dogs are completely different from domestic dogs in size, weight

B. African wild dogs are living in groups

C. African wild dogs use their eyes mostly when sleeping to guard

C. African wild dogs can run at a speed of about 15 m/s for a long distance.

(NEW YORK) A French tourist highly praised for rescuing a two-year-old girl in Manhattan said he didn’t think twice before diving into the freezing East River.

Tuesday’s Daily News said 29-year-old Julien Duret from France was the man who left the spot quickly after the rescue last Saturday.

He lifted the little girl out of the water after she fell off the bank at the South Street Seaport museum. He handed the girl to her father, David Anderson, who had dived in after him.

“I didn’t think at all,” Duret told the Daily News. “It happened very fast. I reacted very fast.”

Duret, an engineer on vacation, was walking with his girlfriend along the pier(码头) when he saw something falling into the water. He thought it was a doll, but realized it was a child when he approached the river. Immediately, he took off his coat and jumped into the water.

When he reached the girl, she appeared lifeless, he said. Fortunately, when she was out of the water, she opened her eyes.

Anderson said his daughter slipped off the bank when he was adjusting his camera. An ambulance came later for her, said Duret, who was handed dry clothes from onlookers. Duret caught a taxi with his girlfriend shortly after.

The rescue happened on the day before he left for France. Duret said he didn’t realize his story of heroism had greatly moved New York until he was leaving the city the next morning.

“I don’t really think I’m a hero,” said Duret. “Anyone would do the same thing.”

1.Why was Duret in New York?

A. To meet his girlfriend. B. To spend his holiday.

C. To work as an engineer. D. To visit the Andersons.

2.What did Duret do shortly after the ambulance came?

A. He was interviewed by a newspaper.

B. He went to the hospital in the ambulance.

C. He disappeared from the spot quickly.

D. He asked his girlfriend for his dry clothes.

3.Which of the following is TRUE according to the passage?

A. Duret thought twice before he jumped into the cold water.

B. Duret dived into the water before the girl’s father.

C. The rescue happened on the day Duret left for France.

D. Duret didn’t think he was brave enough to be a hero.

The sea has always interested man. From it he can get food, minerals, and treasure. 1. But he could not go far beneath its surface.

2. However, he is not a fish. He must breathe air, so he can’t stay under the water’s surface for any length of time. To explore deep water, man faces even more dangers and problems.
