   Recently I was asked,“Are we anywhere near the day when you can climb into a car on Long Island, program it to take you to your niece’s house in Chicago, hit enter, and after the first hundred yards, once you hit a main road, the car takes over automatically and you just sit back and enjoy the ride?”

   It is a question I worry. But I had to answer truthfully:“Absolutely. We are without a doubt near that day.”Look, we’re already doing it with airplanes.

   Northrop Grumman’s Global Hawk takes off at an air base in the U.S., climbs to 50,000 feet, flies to Australia, and lands at an Australian air base, where there is a grandstand filled with military officials=with no human pilot.

   The necessary technology is already here. We have radar technology that can be tied to cruise(巡航)control and brakes, which automatically adjusts(调整)your speed based on following distance and preprogrammed settings. It’s still a little bit raw, but it does work great. The technology can allow cars and trucks to follow each other in very closely spaced roads.

   GPS can also change speed with location. Let’s say you’re in a state with a 75-mph limit and you cross into a state with a 65-mph limit. GPS knows that and adjust your speed accordingly.

   It’s not out of the question to imagine that someday soon you’ll be able to start the car, make proper settings, then turn the front seats around and play cards and eat lunch as if you’re riding on a train. All in perfect comfort and safety, all the way to that niece’s place in Chicago.

   If asked to estimate just how far time is, I’d say a working system is ten years out, practice maybe 20 years.

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

       The most widespread mistake 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 Auschwitz concentration camp(奥斯维辛集中营), naked(裸露的)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 kinds of medicines such as aspirin, but all they do is to relieve the symptoms of colds.

       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 had one.

  51. 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

  52. The passage mainly discusses _________.

       A. the experiments on the common cold

       B. the false idea about the common cold

       C. the reason and the way people catch colds

       D. the continued spread of common colds
