A little under one-third of U.S. families have no Internet access and do not plan to get it, with most of the holdouts seeing little use for it in their lives, according to a survey released on Friday.
Park Associates, a Dallas-based technology market research firm, said 29 percent of U.S. families, or 31 million homes, do not have Internet access and do not intend to subscribe（预订） to an Internet service over the next 12 months. The second annual National Technology Scan conducted by Park found that the main reason why potential customers say they do not subscribe to the Internet is because of the low value to their daily lives rather than concerns over cost.
Forty-four percent of these families say they are not interested in anything on the Internet, versus just 22 percent who say they cannot afford a computer or the cost of Internet service, the survey showed. The answer "I'm not sure how to use the Internet" came from 17 percent of participants who do not subscribe. The response "I do all my e-commerce shopping and YouTube-watching at work" was cited by 14 percent of Internet-access refuseniks. Three percent said the Internet doesn't reach their homes.
The study found U.S. broadband adoption grew to 52 percent over 2006, up from 42 percent in 2005. Roughly half of new subscribers converted（转变） from slower-speed, dial-up Internet access while the other half of families had no prior access.
"The industry continues to chip （击破）away at the core of non-subscribers, but has a long way to go," said John Barrett, director of research at Parks Associates. "Entertainment applications will be the key. If anything will pull in the holdouts, it's
going to be applications that make the Internet more similar to pay-TV," he predicted.What does the underlined word “holdouts” in the first paragraph most probably mean?
| A．some American families |
| B．those who hold out one’s opinions |
| C．those who have been surveyed |
| D．those who still haven’t access to the Internet currently |
Many potential customers refuse to subscribe to the Internet mainly because __________.
| A．they show too much concern about the cost |
| B．they can find little value of it |
| C．they do most YouTube-watching at work |
| D．the Internet doesn’t reach their homes |
From the passage we can infer that _____________.
| A．It is not an easy job to transform those holdouts into the Internet users |
| B．people will adopt dial-up Internet access no more |
| C．many Americans enjoy doing e-commerce shopping at home |
| D．more than half of the population are using the Internet in 2005 |
According to John Barrett, what is the key to attracting more U.S. families to broadband service?
| A．making the Internet look more similar to TV set |
| B．applying the Internet more to entertainment |
| C．providing more pay-TV programs |
| D．chipping away at the core of non-subscribers |
Which is the best title for the passage?
| A．Web develops with technology |
| B．The present situation of web |
| C．Many Americans see little point to web |
| D．It is urgent to promote web service |
A super drug that could remove Alzheimer’s (老年痴呆症)，heart disease and diabetes (糖尿病) and help people live to 100 is being developed by scientists. Their research is based on the identification of three genes that help prolong lives and prevent diseases which occur in old age. Medically controlling the proteins made by the “ longevity genes” will allow millions to live longer, predicts Dr Nir Barzilai.
Those whose DNA strongly features the three genes are 80 percent less likely to develop Alzheimer’s. The genes also fight against the deadly impact of smoking, poor diet, obesity and lack of exercise.
Already, several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage old age. “ The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing,” he said.
Of the three longevity genes, two genes increase the production of so-called good cholesterol(胆固醇), which reduces the risk of heart disease. The third prevents diabetes. They were discovered by Dr Barzilai’s team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the group, which shared relatively few common ancestors, was 20 times more likely to hit the entury. Dr Barzilai said: “ 30 percent of them were obese or overweight and 30 percent smoked two acks of cigarettes a day for more than 40 years, however they can live to 100.”
But Andrew Ketteringham of the Alzheimer’s Society said: “Alzheimer’s disease, a most common disease, is likely to be caused by a combination of genetic disosition(遗传倾向), lifestyles and life events. Many genes are probably involved. Some people are able to live to 100 years because of ______.
| A．a magical medicine | B．three special genes | C．good living habits | D．longevity proteins |
Why does the discovery of the longevity genes mean a lot?
| A．Because it can bring great benefits to scientific labs. |
| B．Because it can help people change their unhealthy genes |
| C．Because it helps produce a drug that can make people live longer. |
| D．Because it will help scientists build up a new branch of biology. |
From Paragraph 4 we can infer that ________.
| A．longevity genes can create good cholesterol. |
| B．the volunteers share some common ancestors |
| C．bad habits are likely to have no effect on the volunteers |
| D．longevity genes protect the volunteers against bad habits |
What is Andrew Ketteringham’s attitude toward the study?
| A．Positive | B．Negative | C．Critical | D．Cautious |
Jeans are trousers made of a kind of clothe called denim. For many people, blue jeans represent American culture.
The history of blue jeans usually begins with a man named Levi Strauss. Although he did not invent the jeans, he is considered the first person to produce and sell this kind of clothing in large amounts.
Levi Strauss was born in Bavaria, Germany. In 1847, he and his family moved to the US. He opened a store, first in New York, and then in San Francisco, California. Among the products he sold were jeans. These trousers were especially useful for miners in California who needed clothing made of a strong material.
Levi Strauss partnered with a clothing maker named Jacob Davis, who had invented a process for making rivets(铆钉) for jeans. These metal things helped strengthen the blue jean cloth to make the trousers stronger. In 1873, Strauss and Davis received a patent to officially own this invention. They began producing “ copper-riveted waist overalls(工装裤)”. In 1928 the Levi Strauss company used the word “Levi’s” as the trademark for their products.
The 19th-century workers would probably be surprised to know that their trousers would one day become a fashion object. Today, jeans are worn by people of all ages, incomes and lifestyles. Jeans come in many colors other than blue and in many styles and at many prices.
A national museum in Washington, D.C. has one of the oldest known pairs of Levi’s jeans in its collection. Jeans have come to express different ideas about American culture based on the people who wear them. These include the heroes of the Wild West and famous Hollywood actors like James Dean and Marlon Brando in the 1950s. Writer James Sullivan published a book called Jean: A Cultural History of an American Icon. In the book, he says jeans serve as a sign for two American values, creativity and rebellion (叛逆).This passage is mainly about _______.
| A．the life story of Levi Strauss | B．jeans and American culture |
| C．why jeans are popular. | D．the history of jeans |
We know from the passage that Levi Strauss _________.
| A．was the first person who wore jeans. | B．moved to the US from Germany alone. |
| C．not only sold jeans at first in his store | D．helped Jacob Davis invent a kind of rivet |
Which of the following statements is TRUE about jeans?

My mother-in-law, Dorothy, is showing me the red notebook that’s almost as precious to her as my husband’s baby pictures. Inside the notebook is a list of the books she has read since 2007. For some people waking up in the middle of the night is a terrible thing. But for my mother-in-law, that time is a gift. At 87, she is getting the education she never had by working her way through great literature. She has now read close to 100 books, including every single novel by Anthony Trollope, Charles Dickens, Jane Austen, Edith Wharton, Henry James and Thomas Mann.
My mother-in-law discusses her passion with the enthusiasm of a young girl, although she can also be a very tough critic, writing “VG’ for “ very good” in the margins next to her favorites. So far, only a handful of books have received the top prize.
Born in Ridgefield, Conn, Dorothy was the youngest daughter of an Italian gardener. She taught herself English by reading The New York Times. Eager to come to Manhattan, she became a nurse, married a dentist and spent the next several decades keeping the house and raising a family. In her later years, she put her nursing skills to good use by taking care of my father-in-law, who had lung cancer. There were many trips to the emergency room in the middle of the night and then a long hospital stay. She stayed awake to watch over him for 15 hours a day. Always a light sleeper, she developed sleeplessness as a result of the stress.
It worsened after he died. Deeply sad and lonely for the first time in her life, she began waking up around 2am. Julian and Sylvia, the elderly couple next door suggest she read literature. And so Julian, a great lover of literature, became her “professor”, providing books from his large library. Suddenly the terrifying hole turned onto a world of amazing characters.Why is Dorothy considered a tough critic?
| A．Because no books are inspiring enough in her eyes. |
| B．Because only a few books are thought highly of by her. |
| C．Because she only reads books by famous writers. |
| D．Because she finds fault with every book she reads. |
It can be inferred from the passage that _____.
| A．the books Dorothy has read were bought by her husband. |
| B．the couple next door are college professors. |
| C．the author loves literature too. |
| D．Dorothy was a great wife. |
The underlined part “the terrifying hole” in the last paragraph refers to _____.
| A．the frightening death |
| B．Dorothy’s lack of education |
| C．waking up in the middle of the night |
| D．a hole in a book that Dorothy read |

Everyday we go to school and listen to the teacher, and the teacher will ask us some questions. Sometimes, the classmates will ask your opinions of the work of the class. When you are telling others in the class what you have found out about these topics, remember that they must be able to hear what you are saying. You are not taking part in a family conversation or having a chat（闲谈）with friends — you are in a slightly unnatural situation where a large group of people will remain silent, waiting to hear what you have to say. You must speak so that they can hear you — loudly enough and clearly enough but without trying to shout of appearing to force yourself.
Remember, too, that it is the same if you are called to an interview whether it is with a professor of your school or a government official who might meet you. The person you are seeing will try to put you at your ease（轻松）but the situation is somewhat（一点儿）different from that of an ordinary conversation. You must take special care that you can be heard.

The Internet has led to a huge increase in credit-card(信用卡) fraud. Your card information could even be for sale in an illegal Web site(网站).Web sites offering cheap goods and services should be regarded with care. On-line shoppers who enter their credit-card information may never receive the goods they bought. The thieves then go shopping with your card number — or sell the information over the Internet.
Computers hackers(黑客) have broken down security(安全) systems, raising questions about the safety of cardholder information. Several months ago, 25 000 customers of CD Universe, an on-line music retailer(批发商),were not lucky. Their names, addresses and credit-card numbers were posted on a Web site after the retailer refused to pay US $157 828 to get back the information.
Credit-card firms are now fighting against on-line fraud. MasterCard is working on plans for Web-only credit card, with a lower credit limit. The card could be used only for shopping on-line.
However, there are a few simple steps you can take to keep from being cheated.
Ask about your credit-card firm's on-line rules: Under British law, cardholders are responsible(对……负有责任的) for the first US $78 of any fraudulent spending.
And shop only at secure sites: Send your credit-card information only if the Web site offers-advanced secure system.
If the security is in place, a letter will appear in the bottom right-hand corner of your screen. The Web site address may also start with https:// — the extra “s” stands for secure. If in doubt, give your credit-card information over the telephone.
Keep your password safe: Most online sites require a user name and password before placing an order. Treat your passwords with care.
