Do you suppose Darwin, one of the greatest scientists of all time, really did foolish experiments? Or did he do experiments that were so simple and basic that other people just thought they were foolish?
Sometimes, people think they already know the answer to a question or the solution to a problem. Sometimes, they really do know an answer or a solution, but without thinking they are important.
Charles Darwin didn’t settle for(满足于)just thinking he knew something. And, he believed all things could be important however simple they seemed to be.
Suppose you drop sheets of paper that are of exactly the same size and shape. If you drop them at the same time in the same place, they will fall in the same way. Now make one of the sheets of paper into a tight little ball and let it drop along with the other sheets. What happens? You have done an experiment that is so simple that you might think it couldn’t be worth anything.
But this simple experiment is important. It explains part of our present-day understandings of physics, ideas that were worked out long ago by Galileo and Newton. And these understandings set aside some of ancient Greek physics.
Scientists sometimes stop to look at very simple things and to think very hard about them. Even the simplest idea, which we might think is foolish, can shake the foundations of science.
The passage tells us that Charles Darwin .
| A．was a great English scientist |
| B．always liked doing the experiments that others thought difficult |
| C．thought even the simplest thing was important |
| D．didn’t get well with others |
The underlined phrase “set aside” most probably means .
| A．throw away | B．store up |
| C．put to use | D．realize |
The author of the passage tries to .
| A．convince us that Charles Darwin, Galileo and Newton are the greatest scientists in the world |
| B．draw the conclusion that basic sciences are simple things |
| C．prove that two sheets of paper, with the same size and shape, will fall at the same speed |
| D．draw our attention to everyday happenings around us |
Which of the following is TRUE?
| A．Darwin really did foolish experiments. |
| B．According to some people Darwin did foolish experiments. |
| C．It is believed by all the people that things could be important though they seemed to be simple. |
| D．Galileo and Newton worked out ancient Greek physics. |
Zinc (锌) is one of about 20 elements necessary for good health. It is present in the body in a very small amount, but it makes it possible for important chemical actions to be carried out in cells. Scientists are just beginning to discover how zinc and other elements work.
Researchers first studied zinc as a way to speed recovery. Dr. Waltor Powys, formerly with the United States Air Force, noted that the laboratory animals recovered faster when some matters were added to their food. One of these matters was zinc. Dr. Powys later tested the zinc treatment on an American airman recovering from medical operations. The airman who received zinc sulphate (硫酸盐) recovered in half of the usual time. Other doctors studied persons who had a number of strange disorders. The doctors learned that all of these problems were caused by lack of zinc in the body. They treated these disorders successfully by giving the patients zinc sulphate.
The amount of zinc in the body can be found by examining blood and hair. A lack of this important element is not uncommon among people in both industrial and developing countries. Zinc is found in most high protein foods, such as meat milk, fish and eggs. It is also found in whole grains. But many people do not eat enough of these foods. Food markets should add these elements so that more people could get needed amount of these necessary matters.

Laptop computers are popular all over the world. People use them on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms.
Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a ＄10 million computer program at Westlake, a 110-year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e-mail to “speak” with their teachers, their classmates, and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees-anywhere at all!
Because of the many changes in computer technology , laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only the Internet, but also libraries and other resources. State higher-education officials are studying how laptops can help students. State officials are also testing laptop programs at other universities, too.
At Westlake College, more than 60 percent of the staff use computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, “ Here we are in the middle of Virginia and we’re giving students a window on the world. They can see everything and do
everything.”

A couple from Minneapolis decided to go to Florida for a long weekend to warm themselves up during one particularly icy cold winter. They planned to stay at the very same hotel where they spent their honeymoon 20 years ago. They both had jobs, so it was decided that her husband would fly to Florida on a Thursday, and his wife would follow him the next day. Upon arriving as planned, the husband checked into the hotel. There he decided to open his laptop(笔记本电脑) and send his wife an e-mail back in Minneapolis. However, he accidentally left off one letter in her address and sent the e-mail without noticing his error.
In the mean time: In Houston, a woman had just returned from her husband’s burial. He was a minister of many years who had been “called home to glory” following a heart attack. The woman checked her e-mail, expecting message from family and friends. Upon reading the first message, she fainted(昏厥)and fell to the floor.

To: My Loving Wife
From: Your Departed Husband
Subject: I’ve arrived!

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.
