Passage One
Everyone needs friends. We all like to feel close to someone. It is nice to have a friend to talk, laugh, and do things with. Surely, there are times when we need to be alone. We don’t always want people around. But we would feel very lonely if we never had a friend.
No two people are just the same. Sometimes friends don’t get along. That doesn’t mean that they no longer like each other. Most of the time they will make up and go on being friends.
Sometimes friends move away. Then we feel very sad. We miss them very much. But we can call them and write to them. It could be that we will never see them again. And we can make new friends. It is surprising to find out how much we like new people when we get to know them.
Families sometimes name their children after a close friend. Many places are named after men and women who have been friendly to people in a town. Some parks are named this way. So are some schools. We think of these people when we go to these places. There’s more good news for people who have friends. They live longer than people who don’t. Why It could be that they are happier. Being happy helps you stay well. Or it could be just knowing that someone cares. If someone cares about you, you take better care of yourself.

Which of the following is NOT mentioned in the passage（）

A:People usually feel depressed when their friends move away. B:People may call and write to their friends. C:People like their new friends very much if they get to know them. D:People must depend upon their friends for everything.

Scientists are racing to build the world’s first thinking robot. This is not science fiction: some say they will have made it by the year 2020. Carol Packer reports.
Machines that walk, speak and feel are no longer science fiction. Kismet is the name of an android (机器人) which scientists have built at the Massachusetts Institute of Technology (MIT). Kismet is different from the traditional robot because it can show human emotions. Its eyes, ears and lips move to show when it feels happy, sad or bored. Kismet is one of the first of a new generation of androids—robots that look like human beings—which can imitate human feelings. Cog, another android invented by the MIT, imitates the action of a mother. However, scientists admit that so far Cog has the mental ability of a two-year-old.
The optimists (乐观主义者) say that by the year 2020 we will have created humanoids (机器人) with brains similar to those of an adult human being. These robots will be designed to look like people to make them more attractive and easier to sell to the public. What kind of jobs will they do In the future, robots like Robonaut, a humanoid invented by NASA, will be doing dangerous jobs, like repairing space stations. They will also be doing more and more of the household work for us. In Japan, scientists are designing androids that will entertain us by dancing and playing the piano.
Some people worry about what the future holds: will robots become monsters (怪物) Will people themselves become increasingly like robots Experts predict that more and more people will be wearing micro-computers, connected to the Internet, in the future. People will have micro-chips in various parts of their body, which will connect them to a wide variety of gadgets (小装置). Perhaps we should not exaggerate (夸大) the importance of technology, but one wonders whether, in years to come, we will still be falling in love, and whether we will still feel pain. Who knows
In the future robots will also

A:explore space. B:entertain people. C:move much faster. D:do all of the housework.

Most of the pioneers of low-temperature physics expected gases to liquefy, but none of them predicted superconductivity. This phenomenon was discovered in 1911 by Onnes while he was studying frozen mercury.
More than 40 years passed before physicists were able to offer an explanation for superconductivity. The accepted theory, developed in the 1950s, holds that the fundamental behavior of electrons changes at very low temperatures because of the effects of quantum mechanics. Electrons are tiny particles that make up the outer part of an atom, circling rapidly around the nucleus of the atom. In a regular conductor—a metal that conducts an electric current—the outermost electrons are not bound tightly to the atoms, and so they move around relatively freely. The flow of these electrons is an electric current.
At normal temperatures, a conductor’s electrons cannot move completely freely through the metal because they are "bumped around" by the metal’s atoms. But according to the leading theory of superconductivity, when a metal is very cold, electrons form pairs. Then, like couples maneuvering on a crowded dance floor but never colliding, the paired electrons are able to move unimpeded through the metal. In pairing up, it seems, the electrons are able to "blend together" and move in unison without resistance.This explanation seems to account for superconductivity at extremely low temperatures, but in 1986 scientists in Switzerland found that some metal-containing ceramics are superconductors at much higher temperatures. By 1992, scientists had developed ceramics that become superconducting at - 297’F, and some researchers speculated that room-temperature superconductors may be possible. Scientists are still trying to formulate a theory for high-temperature superconductivity.The new ceramic materials can be maintained at their superconducting temperatures, with relatively inexpensive liquid nitrogen rather than the much colder and much more costly liquid helium required by metal superconductors. The cost difference could make superconductivity practical for many new technologies. For example, magnetically levitated trains, which require superconducting electromagnets, would be much cheaper to build than they are now. Superconducting devices might also be used for advanced power transmission lines and in new types of compact, ultrafast computers. But for the time being, superconductivity is finding application mostly in scientific research and in some kinds of medical imaging devices.

At very low temperatures, superconductivity in a metal occurs where（　）.

A:electrons do not move freely through the metal B:electrons are crowded together C:paired electrons move uninterruptedly D:paired electron dance together to and fro
