Three-year-old Teddy Lasry was sleeping in his cowboy outfit(套裝)yesterday at his family’s Fifth Ave. apartment when he shot up in bed screaming. A 3-foot-long black-and-white snake twisted around his left arm and had just bitten his little finger,

“The babysitter was frightened to death.” said Teddy’s father David Lasry, who, along with his wife, Evelyn, was at work when the snake appeared about 4:00 pm. The horrified babysitter called 911 and the building’s doorman. The doorman and two cable TV workers helped take the snake off the boy’s arm and put it in a garbage bag. Police rushed Teddy to Mount Sinai Medical Center, where he spent two hours attached to a heart monitor as a precaution in case the snake was poisonous. It wasn’t. Experts at the snakebite treatment center at Jacobi Medical Center in the Bronx, where policemen took the snake, found out it was a non-poisonous California king snake. But how did it end up in Teddy’s bed?

A little detective work determined that the snake had escaped two weeks ago from its cage in the apartment of a doctor whose family lives four floors below the Lasrys. The owner said his son’s pet snake likely traveled up the water pipes and into his neighbor’s apartment. “It’s a very gentle, very harmless snake, ”he said: “It’s handled by our family all the time.”

David Lasry believed the pet was simply hungry after two weeks of wandering. Evelyn said her son seems to have overcome his fright by thinking of himself as a hero cowboy as he rode in the back of the police car to the hospital.

“I told Teddy he’s a pretty snake, a nice pet snake who got out of his cage.” Evelyn said. “But he asked, ‘Why did he bite my finger, Mamma?’ And I said, ‘Because he saw that you are a big boy, Teddy, in your cowboy outfit and he got scared.’”

1.What did the babysitter do after Teddy was bitten by a snake?

A. She ran out of the apartment.

B. She took the snake off Teddy’s arm.

C. She called the TV company.

D. She made an emergency call.

2.We can learn from the passage that the snake_____.

A. was kept in a cage by its owner

B. was poisonous

C. was deserted by its owner

D. escaped to the apartment downstairs

3.Which of the following is true?

A. Teddy was awake when the snake arrived.

B. The snake had never bitten people before.

C. Teddy’s mother was at home when the snake turned up.

D. Teddy needed a heart machine to stay alive for two hours.

4.Teddy probably believed he was attacked because_________.

A. his parents weren’t at home

B. he was asleep

C. the snake was scared of him

D. the snake was hungry

Modern man has cleared the forests for farmland and for wood, and has also carelessly burned them. More than that, though, he has also interfered(干預(yù)) with the invisible bonds between the living things in the forests. There are many examples of this kind of destruction. The harmfulness of man’s interference can be seen in what happened many years ago in the forest of the Kaibab plateau （凱亞巴布高原） of northern Arizona. Man tried to improve on the natural web of forest life and destroyed it instead.

The Kaibab had a storybook forest of large-sized pine, Douglas fir, white fir, blue and Engelmann spruce. In 1882 a visitor noted, "We, who have wandered through its forests and parks, have come to regard it as the most enchanting（迷人的）region it has ever been our privilege to visit. "This was also the living place of the Rocky Mountain mule deer. Indians hunted there every autumn to gather meat and skins. The forest also had mountain lions, timber wolves and bobcats that kept the deer from multiplying too rapidly.

Then, in 1906, President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was forbidden. Government hunters started killing off the deer’s enemies. In 25 years’ time, 6,250 mountain lions, wolves and bobcats were killed. Before the program, there were about 4,000 deer in the Kaibab, by 1924, there were about 100,000.

The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer was permitted again. This caused a slight decrease in the deer herd，but a far greater loss resulted from starvation and disease. Some 60 percent of the deer herd died in two winters. By 1930 the herd had dropped to 20,000 animals. By 1942 it was down to 8,000.

1. The destruction of the environment of the Kaibab resulted from ________ .

A. turning the forest into cultivated land

B. interfering with natural cycle of forest life

C. forest fires caused by man’s carelessness

D. cutting the trees for building materials

2. "Engelmann spruce"（Para. 2）is most likely the name of ________ .

A. a tree B. an animal

C. a mountain D. a game

3. The number of the deer in the Kaibab had increased enormously in

________ years’ time.

A.25 B.6 C.18 D.12

4.Years later, large numbers of deer in the Kaibab died mainly because of

_______.

A. the cold

B. the organized kill

C. the shortage of food

D. the poor management

I was very disappointed not to be able to go to the concert last Friday. The advertisement in the paper said you could buy tickets at the theatre box any day between 10:00 and 4:00. Since I work from 9:00 to 5:30, the only time I could go to the theatre was during my 45-minute lunch break. Unfortunately, the theatre is on the other side of the town, and the bus service between my office and the theatre is not good. But if you are lucky, you can make the round trip in 45 minutes. Last Monday, I stood at the bus stop for 15 minutes. By the time I saw one come, there was not enough time left to make the trip. So I gave up and went back to the office. The same thing happened on Tuesday, and again next day. On Thursday, my luck changed. I got on a bus right away and arrived at the theatre in 20 minutes. When I got there, however, I found a long line at the box office, and I heard one man say he had been waiting for over an hour. Realizing I would not have enough time to wait in line, I caught the next bus and headed back. By Friday I realized my only hope was to make the trip by taxi. It was expensive, but it would be worth it to hear the concert. The trip by taxi only took 10 minutes, but felt like an hour to me. When I got to the theatre, I was relieved to see that nobody was waiting in line. The reason, however, I quickly discovered, was that they had already sold all the tickets.

1. The man learned from _______ that there would be a concert on Friday.

A. the bus stop B. the theatre box

C. one man in line D. the newspaper

2. He tried to go to the theatre every day but managed to get there only _______.

A. once B. three times

C. twice D. four times

3.One day the man took _______ to get to the theatre by bus．

A. forty-five minutes B. twenty minutes

C. fifteen minutes D. ten minutes

4. The underlined word “relieved” may best be replaced by _______.

A. pleased B. surprised

C. puzzled D. sorry
