The fiddler crab (蟹) is a living clock. It shows the time of day by the colour of its skin, which is dark by day and pale by night. The crab’s changing colour follows a regular twenty—four hour plan that exactly matches the daily rhythm of the sun.
Does the crab actually keep time, or does its skin simply answer to the sun’s rays, changing colour according to the amount of light strikes it? To find out, biologists kept crabs in a dark room for two months. Even without daylight, the crab’s skin colour continued to change exactly on time.
This characteristic probably developed gradually in answer to the daily rising and setting of the sun, to help protect the crab from sunlight and enemies. After millions of years it has become completely regulated (受控制) inside the living body of the crab.
The biologists noticed that once each day th
e colour of the fiddler crab is especially dark, and that each day this happens fifty minutes later than on the day before. Fro
m this they discovered that each crab follows not only the rhythm of the sun but also that of the tides (潮水). The crab’s period of greatest darkening is exactly the time of low tide on the beach where it was caught!The fiddler crab is like a clock because it changes colour ______.
A in a regular 24—hour rhythm B. in answer to the sun’s rays
C.
at low tide D. every fifty minutesThe crab’s changing colour ______.
| A．tells the crab what time it is | B．protects the crab from the sunlight and enemies |
| C．keeps the crab warm | D．is of no real use |
When the fiddler crabs were kept in the dark , they ______.
| A．did not change colour | B．changed colour more quickly |
| C．changed colour more slowly | D．changed colour on the same timetable |
The crab’s colour—changing ability was probably developed ______.
| A．in the process of evolution (进化) | B．over millions of years |
| C．by the work of biologists | D．both A and B |
The best title for this selection would be ______.
| A．The Sun and the Tides | B．Discoveries in Biology |
| C．A scientific Study | D．A Living Clock |
When I opened my e-mail the other day, a pretty woman named Rachel appeared on my computer screen. She greeted me by name and started talking with great enthusiasm. Every now and then she stopped to smile at me or blow a kiss. She was reading to me an e-mail from my brother. It was pretty cool.
Rachel was there thanks to a new technology called Facemail. Facemail lets you send an e-mail that gets read to the receiver on line by an attractive male or female or by a clown . The software, which is free, can be downloaded at www.facemail.com. Facemail faces are lifelike, and they simulate （模仿）emotions based on emotions that you put in your text. Type in: -X, and Rachel blows a kiss.
Life FX, the company that develops the Facemail, is sure there are broad business uses. The reason why e-business is not popular, the company says, is that buying over the Internet lacks the human touch. But what if you went to the Nike website and Michael Jordan greeted you by name, waited on you and personally closed the sale? And it is talking with Whirpool Company about using the technology in a computer screen on a fridge. Then if Mom can’t be home when the kids get back from school, she can leave a note with voice and image telling them what there is to eat.
Facemail could get hot fast. Personally, I’m a fan. Facemail is lively and funny at first, but if you select the clown, put a few rude words in an e-mail and add some angry emotions, you’ve got a crazy mail.
67. The main advantage of Facemail is that ________.
A. you can hire a beautiful woman to read the e-mail to you
B. you can see the person who sends you the e-mail
C. you can put your own emotions in the e-mail as you like
D. the e-mail can be read in a more lovely way
68. We can infer from the passage that Facemail _______.
A. is likely to be used in other ways in our daily life
B. can destroy your e-mail if not properly used
C. is a software hard to download
D. will take the place of the e-mail system
69. The writer mentioned Nike website and Michael Jordan to show that ______.
A. famous people like Michael Jordan also like to use Facemail
B. Facemail can make shopping on the Internet more interesting
C. Nike company is increasing its sales through the fame of Jordan
D. Michael Jordan will serve you himself on Nike website
70. The writer thinks _______.
A. Facemail needs further improvement
B. Facemail is cool and funny
C. Facemail is a danger to the Internet
D. people should be careful with Facemail
Attend the Next Forum!
For the last fourteen years CPSB has had the pleasure of hosting a learning event we call a Forum. We started offering programs in Sarasota in February in 1991 and our first Forum was held in 1992 as a small group meeting. Being from the Northern USA, this was a particularly good time to go south for the warmth of our friendship with Dr. Treffinger and Dr. Noller and to keep away from the cold winter.
The Forum is the only chance to learn about various topics of the creativity and innovation（革新）and from those who have rich experience and interest in the field. The theme of the 2005 Forum includes searching for a few new methods, sharing lessons from experience, and learning and exchange ideas on cutting-edge research. Space is limited, so early registration （登记）is welcome.

Perhaps no single monument in the U.S.A. is as famous as the Statue of Liberty. Standing on small island in New York Harbor, the crowned lady, holding high in her right hand the torch of freedom and in her left hand a table with words "July 4th , 1776", is a symbol of American democracy. She is colossal. She is 151 feet high and the pedestal(垫座) on which she stands is almost as much. The Statue of Liberty was a gift to the USA from France in 1886, as a mark of friendship and also in memory of the aid France gave the Americans during the American Revolution.
For millions of immigrants, the Statue was their first sight of the promised land, and for a few also the last, as they sailed back home again. About a mile from Liberty Island, there is another small island, called Ellis Island, which was looked upon with dread by the immigrants. For it was here that they had to wait their turn to be examined by doctors and officials. Most of the immigrants could not speak a word of English. But only two out of 100 immigrants were refused admission to New York City. Often the person refused turned out to be a grandmother or a weary, frightened girl mistakenly labeled "weak-minded". Sometimes husbands and wives were parted because one of them happened to have a bad cough and was suspected of having tuberculosis(肺结核).
New York City was a bitter disillusionment(幻灭) to some immigrants. Far from being a city paved with gold, it was a city teeming with overcrowded, unhealthy and unsafe ghettos(少数民族居住区). The immigrants looked for earlier immigrants of their own nationality or religion. So Italian, Polish, Irish, Jewish neighborhoods grew up. Because they could not speak English, the newcomers found it difficult to get work at once, and their living quarters were often slum.
However, they found in the U.S.A. opportunities of bettering themselves. Today immigrants no longer have to endure the rude treatment of Ellis Island. The unpleasant buildings were closed down in 1924. In 1976, Ellis Island became a historic monument.
59. Which of the following is the best title for this passage?
A. Gateway to the U.S.A.B. The Statue of Liberty.
C. Ellis Island.D. Immigrants of the U.S.A.

61. Immigrants looked upon Ellis Island with dread because ________.
A. they could not speak a word
B. they might be refused admission to the U.S.A.
C. husbands and wives might be recognized
D. they were suspected
62. Paragraph 3 implies that_________.
A. New York City was paved with gold
B. immigrants of the same nationality and religion lived in the same building
C. immigrants lived everywhere
D. some immigrants were disappointed at New York City
CDMA is " spread spectrum (频谱) " technology, which means that it spreads the information contained in a particular signal of interest over a much greater bandwidth (带宽) than the original signal.
When implemented (实现) in a cellular telephone system, CDMA offers numerous benefits to the cellular operators and their subscribers (订户). Following is an overview of CDMA benefits:
1. Improved call quality, with better and more consistent sound.
2. Simplified system planning through the use of the same frequency in every sector of every cell.
3. Increased talk time for portables.
4. Bandwidth on demand.
Compared with GSM ( Global System for Mobile communication ), which was developed mainly in Europe, the CDMA system matured (成熟) later and has better efficiency, low radiation, high voice quality and ability to adopt third-generation communications technology.
China, Indonesia, Japan, South Korea and now India will make up the major market for CDMA technology in addition to the United States, the Republic of Korea, Japan and Australia to ensure that CDMA users can receive phone calls from overseas.
56. Which of the following statements is TRUE?
A. CDMA has a clearer and higher sound than GSM.
