China has mapped out plans for its new launches in the Shenzhou program on the next flight. But one conclusion seems to have escaped most reports in the aerospace media.The flight of Shenzhou 7 could be timed to coincide with the Beijing Olympics. Plans for 2008 Summer Olympics call for the events to be held between the 8th and 24th of August in that year. It's reasonable to expect that China will use the event to display its achievements before the world, and human spaceflight is China's most significant recent breakthrough. Shenzhou 7, China's next manned space mission, was originally advertised for 2007.This fit the pattern of staging a two-gap between crewed Shenzhou missions, which have previously launched in 2003 and 2005.But Chinese media statements have amended this to 2008.Chinese media have reported that the whole program is going well, more time is needed to work on spacesuit that will be used on this flight to stage China's first spacewalk. It's possible that Chinese engineers want to make best preparations for this complex mission. China could intend to carry out the mission of Shenzhou 7 just as media attention is focused on the lead--up to the Olympics. The crew of the fight, and possibly China's other flown astronauts, could then take part in the opening ceremony. China has previously honnoured her space travelers in great celebrations, such as the Hong Kong event that saw Yang Liwei singing with Jacky Chan. China has decided to carry out the human spaceflight in 2008 in order to _ . A) attract more athletes to take part in the Beijing Olympics B) show its great achievements to the whole world C) prove China has become a great developed country like the USA D) introduce its technology to the world

When you turn on the radio, you hear an advertisement. When you watch television, you hear and see an advertisement. If you turn the pages of a newspaper or magazine, again you find an advertisement. If you walk down the street, you see one advertising board after another. All day, every day, people who want to sell you something compete to catch your attention. As a result, advertisements are almost everywhere. In the West, advertisements are the fuel that makes mass media work. Many TV stations, newspapers, magazines, radio stations are privately owned.

First, advertising is usually paid for. Various sponsors pay for the advertisements we see, read, and hear over the various media. Second, advertising is non-personal.

Ques: American's genius with high technology may have put men on the moon, but there is growing doubt about its ability to solve human problems closer to home. In fact, a slight but significant change from purely technological solutions is already under way as scientists insist that answers to the world's problems will not come from an attractive exhibition of electronics and machines. Instead, as they see it, solutions must develop from a better understanding of the humans that drive the system and from a fuller appreciation of the limits and potential of the earth's resources. What this means is an increased emphasis on the life and earth sciences, on sociology, psychology, economics and even philosophy. More and more of the best minds in science, particularly young researchers, are being drawn into these developing fields. All this is not to say that technological creativity will not play a critical role in solving energy and food shortages, or that answers to environmental difficulties will not come from further advances in the same technologies that may have helped cause the problems. Where the real challenge lies, in the view of the new generation of scientists, is in finding ways to produce goods and meet the world's needs, using less of the raw materials that are becoming short. Which of the following best expresses the main idea? A) a growing number of Americans are doubtful about what high technology can do in solving the world's problems. B) Many scientists are beginning to believe that the better understanding of human beings will play a more decisive role in solving the world's problems. C) More and more young scientists are trying their best to find new ways to solve the world's problems. D) Technological creativity will still play a very important part in solving the world's problems.

Ques: It's a time when school,homework,active social lives and pare-time jobs keep teenagers busy from early in the morning until late at night.They are likely to try to make up for a lack of sleep by "sleeping in" on the weekends.Unfortunately,this causes irregular sleep and actually makes the problem worse. Most teenagers are not able to fall asleep until late at night.Since many teens aren't sleepy until around 11 pm.but need to be at school by 7:30 or 8:00 am .They cannot get enough sleep .During puberty ,the biological clock in the brain naturally re-sets to a later time ,and this causes teens to fall asleep later.Then ,when it's time to get up ,a teen's body clock is likely to still be producing the night-time hormones .This makes it hard for them to feel active and energetic in the morning. A growing body of research suggests that starting high school later improves attendance,achievements and grades.A few years ago in an important study ,test scores on the SAT college entrance exams in Edina,Minnesota jumped more than 100 points on average,when the morning school bell rang an hour later.Unfortunately,most schools are not set up to start later and fail to satisfy teen's sleep needs. The study in Minnesota shows that starting morning school one hour later helps to _ . A) make teenagers grow faster B) change teenagers' sleep needs C) do more research on teenagers D) improve students' achievements
Ans:
D
