题目内容

Cold weather can be hard on pets, just like it can be hard on people. Sometimes owners forget that their cats are just as used to the warm shelter (住所) as they are. Some owners will leave their animals outside for a long period of time, thinking that all animals are used to living outdoors. This can put their pets in danger of serious illness. There are things you can do to keep your animal warm and safe.
Keep your pets inside as much as you can when the weather is bad. If you have to take them out, stay outside with them. When you’re cold enough to go inside, they probably are too. If you must leave them outside for a long time, make sure they have a warm, solid shelter against the wind, thick bedding, and plenty of non-frozen water.
If left alone outside, dogs and cats can be very smart in their search for warm shelter. They can dig into snow banks or hide somewhere. Watch them closely when they are left outdoors, and provide them with shelter of good quality. Keep an eye on your pet’s water. Sometimes owners don’t realize that a water bowl has frozen and their pet can’t get anything to drink. Animals that don’t have clean and unfrozen water may drink dirty water outside, which may contain something unhealthy for them.

The common cold is the world's most widespread illness, which is plagues(疫病) that flesh receives.

The most widespread fallacy(谬误) of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.

During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet, showed no increased tendency to catch colds.

In the Second World War prisoners at the notorious Auschwitz Concentration Camp(奥斯维辛集中营), naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.

If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.

No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is relieve the symptoms.

Which of the following does not agree with the chosen passage?

A. The Eskimos do not suffer from colds all the time.

B. Colds are not caused by cold.

C. People suffer from colds just because they like to stay indoors. . .

D. A person may catch a cold by touching someone who already has one.

Arctic explorers may catch colds when .

A. they are working in the isolated arctic regions

B. they are writing reports in terribly cold weather

C. they are free from work in the isolated arctic regions

D. they are coming into touch again with the outside world

Volunteers taking part in the experiments in the Common Cold Research Unit .

A. suffered a lot B. never caught colds C. often caught colds D. became very strong

The passage mainly discusses .

A. the experiments on the common cold B. the fallacy about the common cold

C. the reason and the way people catch colds D. the continued spread of common colds

We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons most of them move to find food more easily, but others move to get away from places that are too crowded. When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration（迁移）is probably the migration of the fish, which is called “salmon”. This fish is born in fresh water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies there. In northern Europe, there is a kind of mice. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.

Recently, scientists have studied the migration of a kind of lobsters（龙虾）. Every year, when the season of bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go. So, sometimes we know why humans and animals move from one place to another, but at other times we don’t. Maybe living things just like to travel.

Most animals move from one place to another at a certain time to __________ .

A. give birth B. enjoy warmer weather

C. find food more easily D. find beautiful places

The fish called “salmon” spends a long life in __________ .

A. salt water B. rivers C. fresh water D. its birthplace

The mice in northern Europe move when __________ .

A. they give birth B. the weather is bad

C. the place gets too crowded D. they haven’t enough food

The lobsters move __________ .

A. to the fresh water B. to the sea floor

C. at a certain time D. to find more food

What is the main idea of the passage?

A. Animals move in order to find food more easily.

B. The migration of the fish called “salmon” is the most famous migration.

C. Living things move from one place to another because they like to travel.

D. Sometimes we know why and how living things move from one place to another, but sometimes we don’t.

Of all the things we eat and drink, water is the most important. Not all people realize this, but it is quite true. The human body can live without food for a long time, but two or three days without water usually result in death.
Many people do not understand how much water the human body needs, but many people do not drink enough, especially in the hot weather. Most people drink when they are thirsty but often need more water after exercises.
65 to 70 percent of the human body is water. Water is important in several different ways. Most people need five to seven liters（升） of water every day, but we needn’t drink this amount(量) because a lot comes from the food we have. If we don’t have enough water, however, we will feel tired and many become ill. Do you know what the best drink is? Yes, you are right. Cool water!

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项.

1.Such as runny noses, sore throats, nothing quite like the common cold to make you feel miserable. But experts believe that there is no link between cold weather and catching colds. 2.

Internal Medicine expert, Dr Meenakshi Jain of Max Hospital says, “One reason could be that people are likely to stay indoors, so the virus can spread easily. 3. ”

The common cold is a viral infection that can be caused by any of up to 250 strains of virus, the most common group of which are the rhinovirus(鼻病毒) that hit the nose.

4.“They are transmitted through the nose respiratory(呼吸的) passages, by touch, and by contact with airborne particles that are created by sneezing or coughing,” says Dr Jain.

There is no cure for the common cold and antibiotics(抗生素) are of no help. However, there are some precautions which can help:

5.In this case, you can protect your hands from getting germs.

Don’t touch your eyes, nose and mouth, which can limit your chances of infection.

Don’t share drinking glasses or utensils with anyone as this will prevent the spread of the virus.

Make sure to eat enough fruits to boost your immune system.

A.Also the virus thrives (兴盛，繁荣) in wetness in the atmosphere.

B.Drink lots of fluids to avoid dehydration.

C.They are responsible for anywhere between a third and half of all common colds.

D.Get enough sleep and you’ll certainly feel better.

E.So why are we particularly vulnerable (脆弱的) this season？

F.Wash your hands regularly.

G.It’s winter and you have probably noticed germs are everywhere.
