Part A
Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D . Mark your answers on ANSWER SHEET 1.
You can't beat it, but you don't have to join it. Maybe it got the name common cold because it's more common in winter. The fact is, though, being cold doesn'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.
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't had the opportunity to become immune to many cold viruses.
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.
Colds are usually spread by direct contact, not sneezing or coughing. From another person'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.
Hygiene is your best defense. Wash your hands frequently preferably with a disinfectant soap, especially when children in your household have colds.
But even careful hygiene won't ward off every cold. So, what works when a coughing, sneezing, runny nose strikes？
The old prescription of two aspirins, lots of water, and bed rest is a good place to start. But you'll also find some of the folk remedies… worth using. Hot mixtures of sugar (or honey), lemon, and water have real benefits.
According to the essay, you may have a cold because______.

Which of the following statements is true according to the passage？

听力原文： When my interest shifted from space to the sea, I never expected it would cause such confusion among my friends, yet I can understand their feelings. As I have been writing and talking about space flight for the best part of 20 years, a sudden switch of interest to the depth of the sea doer seem peculiar. To explain, I'd like to share my reasons behind this unusual change of mind. The first excuse I give is an economic one. Underwater exploration is so much cheaper than space flight. The first round-trip ticket to the moon is going to cost at least 10 billion dollars if you include research and development. By the end of this century, the cost will be down to a few million. On the other hand, the diving suit and a set of basic tools needed for skin-diving can be bought for 20 dollars. My second argument is more philosophical. The ocean, surprisingly enough, has many things in common with space. In their different ways, both sea and space are equally hostile. If we wish to survive in either for any length of time, we need to have mechanical aids. The diving suit helped the design of the space suit. The feelings and the emotions of a man beneath the sea will be much like those of a man beyond the atmosphere.
How did the speaker's friends respond to his change of interest？
