Though “nanometer”（纳米） is now a fashionable term all over the world, few people know
exactly what it is. It has become a new favorite of manufacturers and sellers in recent years.Many “high-tech” products bearing the name “nano” have entered the market,bringing more mysterious feeling to surprised consumers.
Nanometer is a very small length unit of measure,and is very small.One millimeter is 1000 micrometers,and one micrometer is 1000 nanometers.That is,one nanometer is one billionth of a meter.Nano materials are solid materials composed of particles（粒子）or crystallites（晶体） of less than 100 nanometer in size.Then,is a cup made of nano material really any different from an ordinary cup in function as far as how it works?
Are nano cups really so wonderful?A reporter went to the Institute of Nanomedicine,which is the first such institute of such a sort in the world and the only one in China,specializing in researching the investigation of the application of nano technology into medicine.
A water molecule（分子） is composed of 2 hydrogen atoms and 1 oxygen atom.It can be changed only by special manipulation of the atoms. The material constituting the cup can have ananometer particles . But it cannot change the chemical and physical properties of the water contained in it.The water in the cup is still water. When people drink it,it will produce no special effect on human body.
Professor Ji who worked in the Instiute of Nanomedicine told the reporter, so far, the investigation of nano materials is still limited in the laboratory. No commercial micro products can be produced yet. With the present level of science and technology, the time of everyday goods made of nanometer materials is still years away.
The products labeled with nano marks in the market now are only traditional products coated with a thin layer of nanometer material, which makes them more abrasion resistant（耐磨）, much easier to be cleaned, or oil resisting or moth proof（防蛀）.
Professor Ji explained that nano cup is a real up. It can also be included in the list of nano products in a certain sense. But the nano up has not changed its property and function as a cup. It is not a magical medicine for curing and health care.
72．Which of the following shows the right relationship?
A．nanometer<millimeter<micrometer<meter
B．micrometer<millimeter<nanometer<meter
C．nanometer<micrometer<millimeter<meter
D．millimeter<micrometer<nanometer<meter
73．It can be inferred from the passage that       .
A．nano materials have been put into use in daily goods
B．real nano products haven’t become available for people
C．the nano cup is very effective in curing and health care
D．real nano products are being produced by some companies
74．The underlined word “properties” in the fourth paragraph probably means        .
A．possessions      B．qualities    C．reactions   D．symbols
75．What would be the best title for the passage?
A．High-tech Products B．Nano Cups
C．Nano Materials        D．High-teach Research

High-tech machines have made life easier for millions around the world. However, some people still prefer low-tech ways of doing things. Here’s an example of why this is happening. You can microwave a frozen hamburger in 60 seconds. However, it won’t taste as good as one you cook on the stove. And if you’re in that much of a hurry, you probably won’t take time to toast the bun. High-tech cooking saves time, but it doesn’t make for better tasting meals.
Most people get their news from high-tech sources like television or the Internet. This has many advantages. For example, electronic news is more up to date than newspapers

or magazines. It’s also more exciting to see live and videotaped news events than photographs. However, newspapers and magazines have some important advantages. They give more background and details. They also let you read the parts that are important to you and skip the rest.
Other high-tech timesavers have similar disadvantages. For example, most people use the phone or email to stay in touch with friends and family members who live in other places. But when you use the Internet or the phone, you don’t always think carefully about what you are saying, and sometimes you forget the important things you want to communicate. Similarly, when you word process a home work assignment instead of handwriting it, you can check your spelling electronically and put in fancy headings. However, some students are so busy with the computer that they don’t pay enough attention to the actual words they are writing.
72. Which of the following statements is TRUE according to the passage?
A. The writer likes high-tech cooking.
B. Low-tech cooking produces better-tasting meals.
C. High—tech news programs always keep you reading what is important to you.
D. Handwritten homework is better than word-processed homework.
73. How does the writer feel about high—tech tools?
A. Better late than never. B. Easy come, easy go.
C. Every coin has two sides. D. Learn to walk before you run.
74. What is the main subject discussed in the text?
A. High—tech vs. low—tech.
B. Advantages vs. disadvantages.
C. Newspapers and magazines vs. television and the Internet.
D. Word—processing vs. handwriting.
75. How is the text organized?
A. Main idea — Argument — Explanation.
B. Opinion — Discussion — Description.
C. Topic — Comparison — Supporting examples.
D. Introduction — Supporting examples — Discussion.

In learning a foreign language, one should first pay attention to speaking. It is the groundwork of reading and writing. You’d better try your best to speak. Don’t be afraid of making mistakes. But be careful not to let them keep you from improving the language. While you are doing this, a good exercise is to write – keep a diary, write notes, letters or articles, then if you can, ask someone to go through what you have written and tell you where is wrong . Many mistakes in your speaking will be easily found when you write. Through correcting the mistakes, you can do better in learning a language.
If you are slow in speaking, don’t worry. One of the helpful ways is by reading, either aloud or to yourself. The important thing is to choose something interesting to read. It can’t be too difficult for you. When you are reading in this way, don’t stop to look up the words if you can guess their meanings or if they have nothing important to do with the sentence. You can do that some other time.

Because plants cannot move or talk, it is believed that they have no feelings and that they cannot receive signals from outside. However, this may not be completely true.
People who studied plants have found out that plants carry a small electrical charge (电荷). It is possible to measure this charge with a small piece of equipment called “galvanometer”. The galvanometer is placed on a leaf off the plant, and it records any changes in the electrical field of the leaf. Humans have a similar field which can change when we are shocked or frightened.
A man called Backster used a galvanometer for his studies of plants and was very surprised at his results. He found that if he had two or more plants in a room and he began to destroy one of them － perhaps by pulling off its leaves or by pulling it out of its pot － then the galvanometer on the leaves of the other plants showed a change in the electrical field. It seemed as if the plants were signalling a feeling of shock. This happened not only when Backster started to destroy plants, but also when he destroyed other living things such as insects (昆虫).
Backster said that the plants also knew if someone had destroyed a living thing some distance away, because they signalled when a man who had just cut down a tree entered the room.
Another scientist, named Sauvin, achieved similar results to Backster’s. He kept galvanometers fixed to his plants all the time and checked regularly to see what the plants were doing. If he was out of the office, he telephoned to find out about the signals the plants were sending. In this way, he found that the plants were sending out signals at the exact times when he felt strong pleasure or pain. In fact, Sauvin could cause a change in the electrical field of his plants over a distance of a few miles simply by thinking about them.
60. Why was Backster surprised at the results of his studies?
A. Because he found someone had just cut down a tree.
B. Because he destroyed a plant by pulling it out of its pot.
C. Because he found that plants could move and speak after all.
D. Because he found that plants could express feelings of shock.
61. The plants sent out signals _____.
A. only when Backster Started to destroy plants
B. when Backster destroyed plants or other living things
C. only when he destroyed things such as insects
D. only when Backster placed the galvanometer on the leaves of the plants
62. The scientist called Sauvin _____.
A. did not agree with Backster’s ideas
B. did not get the same sort of results as Backster did
C. found out some of the same things that Backster did
D. got different results from Backster’s
63. Which of the following is true according to the passage?
A. The electrical charge plants carry may shock or frighten us.
B. A tree will signal when it has been cut down.
C. Sauvin could make his plants send out signals some distance away.
D. Plants have feelings because they can receive signals without moving.

A new study suggests that the round-the-clock(24小时不断的)availability that cell phone have brought to people’s lives may be taking a toll on family life．The study，which followed more than 1，300 adults over 2 years, found that those who consistently used a mobile phone throughout the study period were more likely to report negative “spillover’’ between work and home life—and，in turn, less satisfaction with their family life.
Spillover essentially(本质上)means that the line between work and home begins to become unclear．Work life may invade home life when a parent is taking job—related calIs at home，for instance--or family issues may start to take up work time．For example，a child may call mom at work，telling her "microwave exploded” explained Noelle Chesley，an assistant professor of sociology at the University of Wisconsin—Milwaukee and the author of the study. The problem with cell phones seems to be that they are allowing for ever more spillover between work and home．
This may be especially true for working women，the study found. Among men，consistent use of mobile phones seemed to allow more work issues to creep (潜入)into family time．But for women，the spillover tended to go in both directions. Being “connected” meant that work cut into home time，and family issues came into work life．
Cell phones seem to be opening more lines for stressful exchanges among family member．But there may be ways to control the spillover，according to Chesley．Employers, she said，could look at their policies on contacting employees after hours to make sure their expectations are “reasonable”．For their part，employees could decide that cell phones go off during family time, Chesley said.
64．What does the underlined phrase “taking a toll on’’ probably mean in Paragraph 1?
A. Explaining. B. Influencing. C. Damaging. D. Extending
65．According to Chesley，what is the best solution to the problem caused by cell
phones?
A. Refuse to use cell phones．
B. Separate work hours from family time．
C. Ignore coming calls during family time．
D. Encourage women to stay at home．
66．We can learn from the passage that ___________________.
A．spillover makes the line between work and home unclear
B．cell phones seem to be convenient to families
C．cell phones affect men as much as women
D．we can do nothing to solve the problem
67. What is the main idea of the passage?
A .How to control the negative spillover caused by cell phones.
B. Cell phones cause negative “spillover’’ between work and home life.
C. Consistent use of cell phones makes people feel less satisfied with their work.
D.How work life invades home life.
