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.

We let ourselves believe that life will be better once we are married, have a baby, then another. Then we get frustrated because our children are not old enough and that all will be well when they are older. Then we are frustrated because they reach teenage years and we must deal with them. Surely we'll be happier when they grow out of the teen years.

We tell ourselves our life will be better when our spouse (配偶) gets his/her act together, when we have a nicer car, when we can take a vacation, when we finally retire. The truth is that there is no better time to be happy than right now. If not, then when? Your life will always be full of challenges. It is better to admit as much and to decide to be happy in spite of it all.

For the longest time, it seemed that life was about to start—real life.

But there were always some obstacles along the way, an ordeal (苦难) to get through, some work to be finished, some time to be given, a bill to be paid. Then life would start. I finally realized that those obstacles were part of life. Little by little, that point of view also helped me see that there isn't any road to happiness.

Happiness is the road. So, enjoy every moment. And keep in mind that __________. So stop waiting for school to end, for a return to school, to lose ten pounds, to gain ten pounds, for work to begin, to get married, for Friday evening, for Sunday morning, waiting for a new car, for your mortgage(借款) to be paid off, for spring, for summer, for fall, for winter, for the first or the fifteenth of the month, for your song to be played on the radio, to die, to be reborn… before deciding to be happy.

Happiness is a voyage, not a destination. There is no better time to be happy than… NOW! Live and enjoy the moment.

The most proper title for the passage should be______.

A. Happiness Is a Frustration B. Happiness Is a Destination

C. Happiness Is a Dream D. Happiness is a Process

Imagine that the genome (基因组) is a book. The book consists of 23 chapters with thousands of stories made up of paragraphs, words and letters on different levels. There are one billion words in the book, which makes it longer than 5,000 volumes the size of this book, or as long as 800 Bibles. If I read the genome out to you at the rate of one word per second for eight hours a day, it would take me a century. If I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube. This is an enormous document. A huge volume, a cook book of great length, and it all fits inside the extremely small nucleus (核) of a tiny cell that fits easily upon the head of a pin.

The idea of the genome as a book is not, strictly speaking, even a metaphor (比喻), It is true to a great extent. A book is a piece of digital information, written in one-directional form and defined by a code that translates a small alphabet of letters into a large dictionary of meanings through the order of their groupings. So is a genome. The only complication is that all English books read from left to right, while some parts of the genome read from left to right, and some from right to left, though never both at the same time.

While English books are written in words of different lengths using twenty-six letters. Genomes are written entirely in three-letter words, using only four letters, And instead of being written on flat pages, they are written on long chains of DNA molecules (分子), The genome is a very clever book, because in the right conditions it can both photocopy itself and read itself.

How do human genomes read according to the passage?

A. Only from left to right. B. Only from right to left.

C. From both directions at the same time D. From one direction at a time
