Dr. Raint Mishor, of Georgetown University Hospital says many people believe it’s possible to become immune to colds. Unfortunately , that’s not the case . “ There are about 200 different viruses that cause the common cold and people think that once you get infected one time you develop immunity for the rest of your life . This is wrong . ‘‘She said .
There are many other common beliefs about colds that medical science doesn’t support. How many of us believe the main cause of the common cold is exposure to cold temperatures? Even some studies have shown that people get sick more frequently during the winter .
But Dr. Mishori says it is not because of cold weather. “ It’s because people tend to congregate and be together and the way the common cold virus is transmitted from one person to another is through handshake , through sneezing , or through coughing on one another.
While there is no actual cure for the common cold , Dr. Mishori says there are still a few things you can do to help reduce its duration and intensity . Though the medical community says Vitamin C does not help prevent colds , there is definitely some proof that it helps keep them from being as bad. “ So if you catch a cold and on day once you start taking about two grams of Vitamin C a day there is evidence that it might shorten the number of days that you will be suffering with these symptoms.” Dr . Mishori stated.
In addition , medical science sys honey and chicken soup are effective against colds. Especially honey .” There is increased evidence that it helps shorten the duration do the common cold sometimes even by two to three days particularly in children,” Dr. Mishori said. “ Chicken soup has anti-inflammatory properties so it helps reduce the duration of the cold but it also helps clear the mucus.
There’s also a common belief that you should “ feed a cold ant starve a fever.” Dr. Mishori says “ not necessary “. ‘ If you do have a cold and you don’t feel like eating anything it’s not going to hurt you bur you have to drink a lot and you can drink water or you can drink tea anything that gets fluids into your body , “ she said , “ That’s very important.”
So if drinking fluids is a good idea What about milk ? “ I will never give milk to a a child who has got bad phlegm. My son used to have that and he would throw up . “ Nadine Audrewy , the Hemmens kids’ grandmother , believes it’s not a good idea to give milk to a child who has a cold .
Well ,says Dr. Mishori ,maybe and maybe not .” Dairy products do not cause increased secretions but they can thicken the secretions,” she explained. ‘So it’s possible that discomfort is somewhat more enhanced when you drink milk , but obviously if you are a baby and its’s all you drink then you should not stop giving babies milk.
There are many other myths about colds that do not pass science muster . Doctors say the best advice is to continue using whatever works best for you . Even if it doesn’t make the cold better , it won’t make it worse either while you wait for the cold to just run its natural course.

In an early survey conducted in 1888, a billion and a half people inhabited the earth. Now, the population exceeds seven billion. This means that the world must accommodate a new population roughly equal to that of the United States and Canada every three years. Even though the rate of growth has begun to slow down, most experts believe the population size will still pass eight billion soon.
If we examine the amount of land available for this ever-increasing population, we begin to see the problem. Everyone on the planet had an equal share of land, we would each have about 50,000 square metres. This figure seems to be quite encouraging until we examine the type of land we would have. Not all land is useful to humans as it cannot produce food. We can cut out about one fifth of it because it is permanently covered by snow and ice. Then we can cut out another one fifth because it is desert. Another fifth is too mountainous or is too great a height above sea-level. A tenth doesn’t have enough soil for crops to grow - it is bare rock. Now the position begins to look rather mom bleak (荒凉)!
Obviously, with so little land to support us, we should be taking great care not to reduce it further. But are we? We are consuming its “ capital” , which means its nonrenewable fossil fuels and other mineral deposits that took millions of years to form but which are now being destroyed in decades. We are also doing the same with other vital resources not usually thought of as being nonrenewable such as fertile soils, groundwater and the millions of other species that share earth with us.
The birth of a baby in, for example, Hong Kong, imposes more than a hundred times the amount of stress on the world's resources as a baby in India. Most people in India do not grow up to own cars or air-conditioners. Nor do they eat the huge amount of meat and fish that the Hong Kong child does. Their life-styles do not require vast quantities of minerals and energy. Also, they are aware of the requirements of the land around them and try to put something back into nature to replace what they take out.
1.Why does the author mention the example of America and Canada?
A.To emphasize that world population has to be reduced.
B.To give a brief history of the population growth.
C.To stress how quickly the world population is rising.
D.To point out what a large population they have.
2.According to the author, how much per person of the earths surface can be used to produce food?
A.15,000 square metres. B.25,000 square metres.
C.30,000 square metres. D.40,000 square metres.
3.Which of the following belongs to vital resources?
A.Fossil fuels. B.Mineral deposits.
C.Chemical fertilizer. D.Groundwater.
4.When can learn from the passage that _____.
A.different lifestyles require similar quantities of resources
B.a Hong Kong baby consumes more resources than an Indian baby
C.tropical forest are being better used for pastureland
D.nature is powerful enough to destroy an aggressive man
