In this century the traditional American family is constantly faced with the threat of breakdown. Some people suggest that one little – noticed cause may be the introduction of the TV dinner.
Before the appearance of television seats, the American dinner was a big event for the family. In many homes dinner time may be the only time when everyone got together. A typical dinner was usually in three periods In the preparation period, the children and Father frequently helped with setting while Mother put the last touches on the roast. In the eating period, family members shared the day’s experiences and more than food was eaten. In this period,families got to know one another and made joint decisions around the dinner table, and thus the family solidarity（团结） was strengthened. In the cleaning – up period,children or Father again gave their hands, so that their meaning to the home community was clear. Unfortunately, all of these have been abandoned by a product—the television set.
By the beginning of the 1980s, the typical American family dinner was just twenty minutes long. The speed – up of this once – leisurely experiences is clearly connected to the overall pace of modern life and maybe a model of the modern life is the TV dinners—meals designed to be used between the opening and closing credits of a half – hour program. The once family affair has now become nothing more than the use of a fork and knife.According to the passage, the American family is now threatened by .
| A．Being poor | B．having few children | C．poor living conditions | D．separation |
In the past, Americans tended to .
| A．spend more time eating their food at dinner table |
| B．eat more food than they have today |
| C．spend more time talking about their day’s experience at dinner table |
| D．talk so much that they forgot to eat |
The shortening of the dinner time in America is related to .
| A．the TV programs | B．the pace of modern life |
| C．the wide use of household appliances | D．the popularity of fast food |
The best title for this passage might be .
| A．Talk At Dinner Table | B．TV Dinner |
| C．Pace Of Modern Life | D．Problems Caused By TV |
If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven’t you noticed that you have become smarter since you started to learn a language?
According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles.
The study also found the effect is greater when the younger people learn a second language. A team led by Dr. Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of “early bilinguals” who had learnt a second language before the age of five, as well as a number of later learners.
Scans showed that grey matter density (密度) in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference.
“Our findings suggest that the structure of the brain is changed by the experience of learning a second language,” said the scientists.
It means that the change itself increases the ability to learn.
Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. “Having two languages gives you two windows on the world and makes the brain more flexible (灵活的),” he said. “You are actually going beyond language and have a better understanding of different ideas.”
The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of two and thirty-four. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. “Studying a language means you get an entrance to another world,” explained the scientists.The main subject talked about in this passage is ________.
| A．science on learning a second language | B．man’s ability of learning a second language |
| C．that language can help brain power | D．language learning and maths study |
The underlined word “bilingual” probably means _______.
| A．a researcher on language learning | B．a second language learner |
| C．a person who can speak two languages | D．an active language learner |
We may know from the scientific findings that ________.
A. the earlier you start to learn a second language, the higher the grey matter density is
Bthere is no difference between a later second language learner and one who doesn’t know a second language
C. the experience of learning a second language has bad effect on people’s brain
D. the ability of learning a second language is changing all the timeIn the last two paragraphs, the author wants to tell us that _________.
A. learning a second language is the same as studying maths
B. early learning of a second language helps you a great deal in studying other subjects
CItalian is the best choice for you as a second language
D. you’d better choose the ages between 2 and 34 to learn a second language
World Expo 2010 Shanghai China is to be staged in Shanghai from May 1 to October 31, 2010. If you plan to visit the Shanghai Expo this summer, China Pavilion(馆)is a must - see area for you.
China Pavilion, which is called Oriental Crown, is located at the center of the Expo site. Standing 63 meters tall, the China Pavilion takes the shape of an emperor's crown, with the upper layers larger than the lower ones. Covering 160,000 square meters in floor space, the pavilion is made up of a national hall and a regional(宗教的 ) hall. Buildings on the China Pavilion began on Dec. 18, 2007. The design of the China Pavilion was picked from a total of 344 designs put forward by Chinese from around the world. The pavilion has both traditional and modern features, which helps develop the theme of the 2010 Expo; "Better City, Better Life. For example, it is red in appearance, which covers the traditional Chinese culture, and it is green indoors, with the use of energy - saving techniques. The Shanghai World Expo is expected to attract 70 million visitors from across the globe. It is estimated that 400,000 people will visit the Expo and its 140 pavilions every day during the period, but the China Pavilion is only able to receive about one tenth of the total. How to hold so many people in the pavilion remains a tough task. Luckily, the China Pavilion is built as a permanent(长久的) landmark.
During the Expo, the main structure(结构 ) will be used for an exhibition based on the theme of “ Chinese wisdom in urban （城市）development” by explaining the values of harmony（和谐）, nature and spirit. The three - story pavilion has three sections. The top floor's “Footprint of the East” will show some of the changes in Chinese cities. There, you can see a film which shows how Chinese cities have changed, especially in the past 30 years. According to Lu Chuan, director of the film, the scenery is like something from Lord of the Rings. On the second floor, “Journey of Wisdom” will explain China's four great inventions. And the ground's “ Blossoming” City will display scenes from cities of the future. Which of the following words can be used to describe the China Pavilion?

“Birds are not as loyal to their partners as you might think, with divorce, child abandonment and remarriage a common part of birds’ life,” a new book has shown. Author and biology professor Bridge Stutchbury, dispels the love-bird belief that birds pair up for life. “In terms of the top 10 beliefs about birds, the lasting pair bonds that we think about, do occur in some birds, but in most of the little songbirds that we studied, no,” the professor from York University in Toronto said. The divorce rate among greater flamingos is 99 percent.
Stutchbury’s book, The Private Lives of Birds, based on 20 years of research from radio filming and DNA testing shows male Acadian flycatchers fertilize(使受孕) females far away from their home nests, “ The main discovery is that so many birds do divorce for what humans would describe as selfish reasons,” Professor Stutchbury said. She noted that females may seek out males that are more colorful and better singers, or look to “step up in the world” and move to areas that are safer and have more food. “Females are looking for the highest quality male so that their children will be of high quality,” she added.
Professor Stutchbury said shorter summers may drive females to leave their nests before their young are fully grown up so they can quickly find new mates（配偶） and lay more eggs, leaving the males to feed the hungry chicks on their own.
Males can double their success in producing children by fertilizing neighboring females, but only “mates” care for the young, and some are none the wiser. “ They can’t tell when the egg comes out and whether it’s theirs or not,” She said. “They have no way to know.”
Divorce is surprisingly common among birds, and most live with one partner for only a few months or years. Divorce rates range from 99 percent in the greater flamingo to zero in the wandering albatross(信天翁).What does the underline word “dispels” mean?
| A．States | B．Doubts | C．Confirms | D．Removes |
The book The Private Lives of Birds_____.
| A．shows the kind of male birds females seek out. |
| B．indicates the wandering albatross is the most faithful. |
| C．is based on Professor Stutchbury’s 20 years’ research. |
| D．suggests that female birds select males near their home. |
According to the passage, we can infer that________.
| A．young birds’ quality depends on their feather. |
| B．some male birds care for others’ young as their own. |
| C．female birds go to find males as soon as autumn comes. |
| D．female birds are responsible for feeding the hungry babies. |
What is the passage mainly about?
| A．A book about love-birds. |
| B．Birds’ living habits and love life |
| C．The fact that birds don’t love their mates forever. |
| D．The factors that influence birds to look for another mate. |
