From the passage, which of the following is thought to be the reason for sleep-deficit? A. The light bulb was invented. B. People have to work harder than they used to. C. People have more time to relax themselves at night. D. Shorter-hour sleep can make people more energetic. D Scientists say that air pollution causes downfall in the world’s average air temperature. In order to prove that theory, ecologistshave turned to historical facts in relation to especially huge volcanic eruptions.They suspect that volcanoes effect weather changes that are similar to air pollution. One source of information is the effect of the eruption of Tambora, a volcano in Sumbawa, the Dutch East Indies, in April 1815.The largest recorded volcanic eruption, Tambora threw 150 million tons of fine ash into the air. The ash from a volcano spreads worldwide in a few days and remains in the air for years. Its effect is to turn incoming solar radiation back into space and thus cool the earth. For example, records of weather in England show that between April and November 1815,the average temperature had fallen 4.50F. During the next twenty-four months, England suffered one of the coldest periods of its history. Farmer’s records from April 1815 to December 1818 indicate frost throughout the spring and summer and sharp decreases in crop and farm animal markets. Since there was a time of several years between cause and effect, by the time the world agricultural product community had worsened, no one realized the cause. Ecologists today warn that we face a double threat. The ever-present possibility of volcanic eruptions, such as that of Mt. St. Helens in Washington, added to man’s pollution of the atmosphere with oil, gas, coal, and other polluting substance, may bring us increasingly colder weather. 查看更多

 

题目列表(包括答案和解析)

Even if you are an experienced backpacker or climber,you need to know what to do if something goes wrong.It is not that Alaska is that much more dangerous than other places.It is no more hazardous than elsewhere,as long as the proper precautions(预防措施)are taken.So, being prepared is crucial to ensure a safe trip.

First of all,make sure you pack everything you will need for your trip.Even if you are traveling by car,pack clothes and gear for backpacking.Because of the bad weather, cars break down frequently. Pack a survival(生存)kit full with:a down coat, boots ,mittens, a hat, snow-pants,sleeping bags,candles,a flashlight,and high-energy food. If you are traveling by car , also pack extra belts, a shovel, and a chain.

If you are camping or hiking,make sure you know how to avoid bears.If you are lost in the wilderness, there is no doubt you will encounter them.

However,there is no need to be nervous.Just take these precautions:make noise as you walk,bears will avoid you;cook your food away from where you sleep,and store your food away from where you sleep,so the bears are not attracted.Both of these should keep the bear away.However,if you do encounter a bear,there are two different schools of thought.One is to make noise and scare the bear away.The other is to stand still and speak softly to get the bear to leave.If you are dealing with a brown bear,you can climb a tree,since it cannot follow.But,black bears can climb.If for some reason the bear attacks,play dead.Try to protect your head and neck,and hopefully the bear will leave its“dead” prey.

The Man was very sad. He knew that the Cat's days were numbered. The doctor had said there wasn’t anything more that could be done, and that he should take the Cat home and make him as comfortable as possible.

A tear rolled down the Man’s cheek and landed on the Cat’s forehead, The Cat gave him a slightly annoyed look. “Why do you cry, Man?” the Cat asked. “Because you can’t bear the thought of losing me? Because you think you can never replace me?” The Man nodded “yes”.

“Pick up that piece of string from the floor~~there, my ‘toy’ The Man reached over and picked up the string. It was about two feet long and the Cat had been able to entertain himself for hours with it. “Now take each end of the string in one hand,” the Cat ordered. The Man did so.

“The end in your left hand is my birth and the end in your right hand is my death. Now bring the two ends together,” the Cat said. The man did so. Then the Cat continued, “You have made a continuous circle. Does any point along the string appear to be different, worse or better than any other part of the string?” The Man inspected the string and then shook his head.

“Close your eyes.” the Cat said. “Now lick your hand.” The Man widened his eyes in surprise. “Just do it,” the Cat said. “Lick your hand, think of me in all my familiar places, and think about all the pieces of string.”

Licking his hand, he discovered what a cat must know, that licking a paw is very calming and allows one to think more clearly. He continued licking and the corners of his mouth turned upward into the first smile he had shown in days. He waited for the Cat to tell him to stop, and when he didn’t, he opened his eyes. The Cat’s eyes were closed. The Man stroked the warm, brown fur, but the Cat was gone.

One day, not long after, there was a new cat on his lap. She was a lovely calico and white.

It is very different from his earlier beloved Cat and very much the same.

1.Why did the Cat give the man a slightly annoyed look?

A.Because the man’s tears made the Cat really anxious.

B.Because the Cat didn’t know what made the man burst into tears.

C.Because the Cat couldn’t go to sleep when the man was in low spirits.

D.Because the man didn’t have to be so sad and concerned.

2.According to the text, which of the following is the reason why a cat licks paws?

A.Licking paws can make a cat remain calm and have a clear mind.

B.Licking paws will make a cat happy and energetic.

C.Licking paws will make a cat find out many unknown secrets.

D.Licking paws can make a cat stay tidy and healthy.

3.What does the underlined word “string” in paragraph 3 stand for?

A Swedish man was dug out alive after being snowed in his car on a forest track for two months with no food, police and local media reported on Saturday.
The 45-year-old from southern Sweden was found on Friday, February17, too weak to say more than a few words.
He was found not far from the city of Umea in the north of Sweden by snowmobilers who thought they had come across a ruined car until they dug their way to a window and saw movement inside.
The man, who was lying in the back seat in a sleeping bag, said he had been in the car since December 19.
“Just incredible that he’s alive considering that he had no food, but also since it’s been really cold for some time after Christmas.” a rescue team member told regional daily Vasterbottens- Kuriren, which broke the news.

Umea University Hospital, where the man is recovering after being rescued by police and a rescue team, said in a statement he was doing well considering the circumstances.
Doctors at the hospital said humans would normally be able to survive for about four weeks without food. Besides eating snow, the man probably survived by going into a dormant-like(休眠似的) state, physician Stefan Branth told Vasterbottens-Kuriren.
“A bit like a bear that hibernates. Humans can do that.” he said. “He probably had a body temperature of around 31 degrees which the body adjusted to. Due to the low temperature, not much energy was used up.”
