  It is only a shiny, yellow metal, but it is one of the most valuable things on earth. Since the beginning of time, men have looked for this extremely valuable item, gold.

  Gold is soft and easy to form into different objects. If it gets wet, it does not rust like iron or other metals. Acids(酸)don't change it. One important reason why gold is so valuable is that it is scarce. Because of its softness, gold must be combined with other metals and so make it harden and give it strength. By hardening gold, people can then make coins and jewelry with it. Metals commonly mixed with gold are nickel(镍), platinum(铂)and copper. Gold jewelry bears(刻有)a number and the letter K. The K means karat (carat), which is a measure of the amount of pure gold in the jewelry. Pure gold is 24K. Therefore, a necklace which is 14K is fourteen parts of gold and ten parts of other metals.

  Many countries make use of gold for certain coins, but this practice is not as common now as it once was. The United States, for instance, stopped making gold coins in1933.

(1) Which of the following would be the best title for this passage?

[  ]

A.Valuable Metal.

B.Looking for Gold.

C.Jewelry and Coins.

D.What is Karat?

(2) Which is not the reason why gold is highly valuable?

[  ]

A.It can be made into jewelry.

B.It is not easily found.

C.It is soft and shiny.

D.It doesn't rust(生锈)when wet.

(3) In order to make it stronger, gold is often mixed with ______.

[  ]

A.hard gold

B.coins and jewelry

C.acids(酸)

D.other metals

(4) If a ring is marked 12K, then the percentage of gold is _____.

  It looks like a mobile phone, but the service is much cheaper. It acts like a mobile phone, but only in your own city. Beyond the city walls, it's useless.

  If you are enjoying such a service, you are one of a growing number users of “Little Smart” in China.“Little Smart”, also called “Xiaolingtong”, has always been compared to mobile phones. But actually, it is more like one of those cordless phones(无线电话)used around the home. The only difference is that this one reaches much further than from the bathroom to the living room. It can travel across an entire city.

  Cheap costs are the main reason for the success of Little Smart. It costs 25 yuan a month for the line and about 0.1 yuan per minute to use. A mobile phone, on the other hand, can cost four or five times as much. What's more, unlike mobile phone, there is no fee for incoming calls.

  These low changes have attracted many users. Since it was first established in Zhejiang in 1998, Little Smart had spread to 300 cities with 12 million users in China by the end of last year.

  But, Little Smart is not really that smart. Users often complain about its bad voice quality. The system uses the fixed phone lines and has a great number of base stations placed close to each other to send the signals. And there are not as many stations to pick up its signals as there are for mobiles. “I couldn't receive a phone call if I was on a bus,” said Li Ping, a user in Hangzhou. “It worked fine when I stood still, but there were breaks in the signal when I was moving. People calling me would get angry because they kept thinking I have hung up on them.”

  Scientists are trying to make Little Smart more user-friendly. Messaging and Internet access has been added to the service. And the latest Little Smart hand-set even have a color screen

  Your body is made up of little cells(细胞).Each one of these is alive. The big difference between your body and a man-made machine is that every part of your body is alive. Each cell has a job to do and needs energy to do it. If you count correctly, you will find the total is around 60,000,000 cells.

  Nerve(神经)cells have long thread like shapes. Bone cells may have branching parts to link with other cells, while red blood cells are round and almost flat.

  The cells are alive, but they do not live nearly as long as you do. Each cell lives for a while--from a few weeks to a year or more--and then it dies and a new cell is made to do the same. Only one kind of cell is not made after birth, the brain cells. So a new born baby is the brainiest person in the world, he has a full set of brain cells in thinking.

  All our lives, we are storing more and more information in the brain. The fastest rate is at the time when we are young.

  Men sometimes say, “We are better and cleverer than women. Women never invent things, we do.” It is true that men have invented a lot of useful things. But scientists and archaeologists(考古学家)now agree that women invented one very important thing. It has changed history. They invented agriculture. Before the invention of agriculture, men were hunters. They went out every day. Sometimes they killed animals, sometimes animals killed them. Life was difficult and dangerous. Women had to go out every day, too. They collected roots, fruit and grasses. Then, one day more than 10,000 years ago, a woman dropped some grass seeds. They grew--and the first wheat was born. The idea grew, too. Women planted roots and fruit trees. Then they could stay at home and look after the children and the animals they kept. Women like baby animals. Archaeologists think that women kept the first domestic(驯养的)animals:dogs, cows, sheep and goats. That idea grew, too. Then their husbands didn't have to go hunting for meat. They stayed at home. They built villages and cities. Civilization(文明)began.

  Smoking, which may be a pleasure for some people, is a serious reason of discomfort for their fellows. Medical scientists have expressed their concern about the effect of smoking on the health not only of those who smoke but also of those who don't. In fact non-smokers who take in the air polluted by tobacco smoke suffer more than the smokers themselves. A great number of students have joined in an effort to persuade the university to forbid smoking in classrooms. I believe they are entirely right in their air. However, I think it more important to achieve this by calling on the smokers to use good judgment and to show concern for others.

  Have you ever been afraid to talk back when you were treated unfairly? Have you ever bought something just because the salesman talked you into it? Many people are afraid to support themselves. Dr Robert Albert, author of Stand Up, Speak Out, and Talk Back thinks it's because their self-respect is low. “There's always a'superior' around--a parent, a teacher, a boss--who knows better.”

  But Albert and other scientists are doing something to help people help themselves. They offer“assertiveness(维护)training” courses--A. T. for short. In the A.T. Course people learn that they have a right to be themselves. They learn to speak out and feel good about doing so. They learn to be aggressive(进攻的)without hurting other people.

  In one way, learning to speak out is to get rid of fear. A group taking an A.T. Course will help the timid(懦弱的)person to lose his fear. But A. T. uses an even stronger motive(动机)--the need to share. The timid person speaks out in the group because he wants to tell how he feels. Whether or not you speak up for yourself depends on your self-respect, If someone you face is more“important”than you, you may feel less of a person. You start to doubt your answers to problems. You can get to feel good about your self. And once you do you can learn to speak out.

(1) The problem the writer talks about is that ______.

[  ]

A.some people have a low sell-respect

[  ]

A.make people distrust their own answers

[  ]
