根据材料,回答题。

The Cold Places

The Arctic is a polar region. It surrounds the North Pole.

Like Antarctica, the Arctic is a land of ice and snow. Antarctica holds the record for a low temperature reading——125 degrees Fahrenheit below zero~ Reading of 85 degrees below zero is common in both the Arctic and Antarctica. Winter temperatures average 30 degrees below zero in the Arctic. At the South Pole the winter average is about 73 degrees below zero.

One thing alone makes it almost impossible for men to live in Antarctica and in parts of the Arctic. This one thing is the low temperature——the killing chili of far North and the polar South.

To survive, men must wear the warmest possible clothing. They must build windproof shelters. They must keep heaters going at all times. Not ever for a moment can they be unprotected "against the below-zero temperatures.

Men have a way of providing for themselves. Polar explorers wrap themselves in warm coatsand furs. The cold makes life difficult. But the explorers can stay alive.

What albout animals? Can they survive? Do we find plants? Do we find life in the Arctic andin Antarctica? Yes, we do. There is life in the oceans. There is life on land.

Antarctica, as we have seen, is a cold place indeed. But this has not always been the case.

Expedition scientists have discovered that Antarctica has not always been a frozen continent. At one time the weather in Antarctica may have much like our own.

Explorers have discovered coal in Antarctica. This leads them to believe that Antarctica at one time was a land of swamps and forests. Heat and moisture must have kept the trees in the forests alive.

The lowest temperature that man has ever known was recorded in Antarctica. 查看材料

A.Right

B.Wrong

C.Not mentioned

请根据短文的内容,回答题。

Common-cold Sense

You can&39;t beat it, but you don&39;t have to join it. Maybe it got the name "common cold" because it&39;s more common in winter. The fact is, though, being cold doesn&39;t have anything to do with getting one. Colds are caused by the spread of rhinoviruses, and, at least so far, medical science is better at telling you how to avoid getting one than how to get rid of one.<br>

Children are the most common way cold viruses are spread to adults, because they have more colds than adults -- an average of about eight per year. Why do kids seem so much more easily to get colds than their parents? Simple. They haven&39;t had the opportunity to become immune to many cold viruses.<br>

There are more than 150 different cold viruses, and you never have the same one twice. Being infected by one makes you immune to it -- but only it.<br>

Colds are usually spread by direct contact, not sneezing or coughing. From another person&39;s hand to your hand and then to your nose or eyes is the most common route. The highest concentration of cold viruses anywhere is found under the thumbnails of a boy, although the viruses can survive for hours on skin or other smooth surfaces.<br>

Hygiene is your best defense. Wash your hands frequently, preferably with a disinfectant soap,especially when children in your household have colds.<br>

But even careful hygiene won&39;t ward off every cold. So, what works when a coughing, sneezing, runny nose strikes?<br>

The old prescription of two aspirins, lots of water, and bed rest is a good place to start. But you&39;ll also find some of the folk remedies worth trying. Hot mixtures of sugar(or honey), lemon,and water have real benefits.

According to the essay, you may have a cold because__________. 查看材料

A.the weather is too cold

B.the spread of rhinoviruses gets people infected

C.another person"s coughing passes the cold to you

D.you wash your hands too often

根据下面材料,回答题。

Sleepless at Night

It was a normal summer night. Humidity (湿气) hung in the thick air. I couldn&39;t go to sleep,partly because of my cold and partly because of my expectations for the next day. My mum had said that tomorrow was going to be a surprise.

Sweat stuck to my aching body. Finally, I gathered enough strength to sit up. I looked out of my small window into the night. There was a big bright moon hanging in the sky, giving off a magic light.

I couldn&39;t stand the pressure anymore, so I did what I always do to make myself feel better. I went to the bathroom and picked up my toothbrush and toothpaste. I cleaned my teeth as if there was no tomorrow. Back and forth, up and down.

Then I walked downstairs to look for some signs of movement, some life. Gladiator, my cat frightened me as he meowed (喵喵地唱出) his sad song. He was on the old orange couch (长沙发),sitting up on his front legs, waiting for something to happen. He looked at me as if to show "I&39;m lonely, pet me. I need a good hug (紧抱)." Even the couch begged me to sit on it.

In one movement I settled down onto the soft couch. This couch represented my parents&39; marriage, my birth, and hundreds of other little events.

As I held Gladiator, my heart started beating heavily. My mind was flooded with questions:

What&39;s life? Am I really alive? Are you listening to me? Every time I moved my hand down Gladiator&39;s body, I had a new thought; each touch sang a different song.

I forgot all about the heat and the next day&39;s surprise. The atmosphere was so full of warmth and silence that I sank into its arms. Falling asleep with the big cat in my arms, I felt all my worries slowly move away.

The author of the passage could not go to sleep partly because__________. 查看材料

A.it was too cold

B.it was too dry

C.he had a cold

D.he had a fever

The space temperatures just discussed affect only our area of the solar __________(5).

Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about -210~C. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your __________(6).
