Grace Brown leads a busy school life. Apart from the many required subjects, the 14-year-old also sings in a choir (合唱团) and plays the piano. The school day lasts from 8 a.m. to 4 p.m., but Grace has so many activities to attend that she has no time for P. E.classes. That’s why Grace has chosen to take P. E. classes on her own time. Her school has allowed her to try “virtual” P. E.. For many subjects, tests and textbooks have become available on computers. Now, new technologies are also having an effect on P. E.. Grace wears a fitness tracker(追踪设备) called Fitbit on her arm while exercising. She usually exercises three times a week for 30 minutes each time. A program on her computer records her activity. Grace needs to hand in the records to her school every week. “Virtual” P. E. is becoming more and more popular among teenagers. Usually, P. E. teachers don’t guide their Fitbit-wearing students in real time. But they do lead the students’ work by setting goals. The students can choose their favorite activities. Those who swim or dance all year round may easily meet the workout requirements. As for Grace, she has added light running and cycling to her days. Some schools, however, do not support this trend. “Physical activity is different from physical education,” said a P. E. teacher. “Physical activity is great for the body. Everybody is moving. But in P. E. classes, students are taught not only how to move but also things like teamwork.【小题1】Grace has so many activities to attend that she has to _________.

英文阅读理解Directions: Read the following passages carefully and choose the best answer from the four choices marked A, B, C and D. Questions 1 to 5 are based on the same passage or dialog.Language is a way to communicate with each other. We started to learn language when we were born. However, people are used to speaking their native language, so immigrants are having many problems between the first generation and the second generation because they don't have the same native language. Also, the second generation is losing their identity. Especially in America, there are many immigrants that came from different countries to succeed in the States. Because they suffer in lots of areas such as getting a job and trying to speak English, they want their children to speak English, not only at school, but also at home in order to be more successful. Because of this situation, their children are losing their ethnic identity and, even more, they are ignoring their parents whose English is not very good.I think most immigrants are trying to preserve their native language in their new country, but this doesn't help very much in getting a good job. My aunt didn't teach Korean to her children in order to help them succeed in the US; she did so, hopefully, to help them establish a Korean identity. Though the second generation is born in the new country, they often get confused about their identity. My cousins told me that when they visited Korea a few years ago, they felt different from other Koreans. They could even feel it just strolling around the street because they wore different clothes.We must realize that language is important and valuable for many reasons. Immigrants should make an effort not to be ignored by their children and to make their children understand their heritage by teaching them the parents' language. This is important in helping the second generation establish their identity.1. Which people are having trouble with language? A. Natives. B. People of the 2nd generation. C. People when born. D. Immigrants. 2. Why are children ignoring their parents? A. Children have lost their identity. B. Parents cause children to suffer. C. They speak different languages. D. They have different job levels. 3. The author's aunt taught Korean ________. A. so she could preserve her language B. so she would have a job in America C. to help children succeed in their new country D. to help children keep their Korean identity 4. The author's cousins felt ________. A. they were not similar to people in Korea B. they could not get a job in America C. it was all right to look and feel different D. it was important to keep their identity 5. A proper title for this passage is ________. A. The Identity of the Second Generation B. Korean Problems in America C. Learning a New Language in the US D. Keeping Your Culture in a New Land

The Harry Potter series, written by J.K. Rowling, is perhaps the most popular set of novels of the modern era. With seven books and many successful films to its name, the series has gathered about 15 billion dollars in sales. How did the series become so popular? The reason can be broken down into several areas.The first book in the series was rejected 12 times before it was picked up by Bloomsbury—a small publisher in England. So receiving this contract was Rowling's first step to success. However, getting a book contract does not ensure the success of a book. The story was soon loved by children and adults alike. In light of this, Bloomsbury Publishing published a second version of the books with “adult” (less colorful and more boring) book covers. This made it easier for a full range of ages to enjoy the series.Another factor that worked like a charm was that the publisher and Rowling herself, through the books, conducted midnight releases, promotions, and pre-ordering more readers. Customers who feared that their local bookstore would run out of copies responded by pre-ordering over 700,000 copies before the July 8, 2000 release.What does the underlined word “releases” (Para. 3) mean?A. The activity that frees or expresses energy or emotion.B. The announcement about the book’s publishing information.C. The sales of books that is available only at midnight.
The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding. [共5题](1)What kind of manager is needed in present international business and foreign investment? [本题2分]A. The man who represents a large multi-million-dollar corporation. B. The man with knowledge of foreign languages and skills in cross-cultural communication. C. The man who is wealthy and impersonal. D. The man who can negotiate with his foreign counterparts.

question or statement.Hot pot is a traditional dish in China. It is believed to date back more than 1,000 years to the time of the Jin Dynasty. Hot pot's origins can be found in the dining practices of Mongolian horsemen who rode across the steppe and into northern China. Legend has it that the Mongols used their helmets as pots to simmer (炖) broth (汤底) over open fires, and cooked chunks of meat in the broth.Hot pot cooking seems to have spread to northern China during the Tang Dynasty. In the regional variations developed with different ingredients such as seafood. In the centuries that witnessed the growth of the Song Dynasty, hot pot moved — and changed — further south, with each successive region adapting it to their local ingredients and tastes.The ingredients in a hot pot vary a lot from region to region. Perhaps the most famous hot pot is the Chongqing or Sichuan hot pot. It features a dark red broth chock-full (塞满了的) of spices, chili peppers, and the uniquely mouth-numbing Sichuan peppers. In Beijing and elsewhere in the north, hot pot broth tends to be mild and, compared to its racy southern "cousins", a little light. In the northeast of China, a kind of local sauerkraut (酸菜) is used to add some tang (强烈的味道), making the broth a bit sour. People can choose a version of hot pot according to their taste.1 Hot pot is believed to date back more than 1,000 years to the time of _______.A. the Jin Dynasty B. the Tang DynastyC. the Song Dynasty D. the Yuan Dynasty
