Being able to multitask-doing several things at the same time-is considered a welcome skill by most people. But if we consider the situation of the young people aged from eight to eighteen, we should think again.
What we often see nowadays is that young people juggle an ever larger number of electronic devices(电子产品)as they study. While working, they also surf on the Internet, send out emails, answer the telephone and listen to music on their iPods. In a sense, they are spending a significant amount of time in fruitless efforts as they multitask.
Multitasking is even changing the relationship between family members. As young people around them. They can no longer greet family members when they enter the house, nor can they cat at the family table.
Multitasking also affects young people's performance at university and in the workplace. When asked about their opinion of the effect of modern gadgets(器具)on their performance of tasks, many young people gave a positive response(反应). However, the response from the worlds of education and business was not quite as positive. Educators feel that multitasking by children has a serious effect on later development of study skills. They believe that many college students now need help to improve their study skills. Similarly, employers feel that young people entering the job market need to be taught all over again, as modern gadgets have made it unnecessary for them to learn special skills to do their work.

Tests administered（实施）to most elementary and high-school students in the United States exert（发挥）an unfavorable influence on science and math teaching， according to a new ＄1 million study performed for the National Science Foundation．And because schools with high minority enrollments（入学）generally place a greater reliance（相信）on scores from these tests， the study finds，there tends to be “a gap in instructional emphases between high and low minority classrooms that differs from our national concern for the quality of education．”
George F．Madaus and his colleagues at Boston College analyzed not only the six most widely used national standardized tests， but also the tests designed to accompany（go with）the four most commonly used science and math texts in fourth-grade，eighth-grade，and high-school classrooms．Though curriculum（teaching program）experts argue that schools should place greater emphasis on problem solving and reasoning， the new study shows that the tests focus on lower-level skills—primarily mechanical memorization of routine formulas（公式）．
Researchers surveyed more than 2，200 math and science instructors，interviewing in depth some 300 teachers and administrators．Especially in schools with high minority enrollments，teachers reported feeling pressured to help students perform well on these tests．Some states judge schools and some schools determine teacher assignments（工作安排）based on students' test scores．
“With so much worry，”Madaus says，“teachers feel forced to focus their instruction on drilling what the tests will measure—at the expense of the more valuable，higher-level skills．”The author of this article states that ____ _ ．
| A．the tests don't affect teaching in most elementary and high schools |
| B．the science and math teaching is influenced by the present tests |
| C．no study is performed on tests for the National Science Foundation |
| D．the United States exerts a strong influence on science and math teaching |
It can be inferred that in high minority classrooms ____ _ ．
| A．the students can not get high score from the tests |
| B．scores from the tests are not important |
| C．instructional emphases are unfavourable |
| D．teaching doesn't focus on the quality of education |
According to the second paragraph，the study has discovered that ____ _ ．
| A．emphasis of teaching is on problem solving and reasoning |
| B．curriculum is good for national standardized tests |
| C．the tests mainly center around the memorization of some formulas |
| D．routine formulas are not useful for students to memorize |
According to Madaus' opinion，teachers are forced to ____ _ ．
| A．evaluate（评估）students' skills every year |
| B．suffer so much worry on the texts |
| C．teach what will be tested |
| D．focus their instruction on useful drillings |
Anti-bird flu contingency (意外事故) measures, including a proposal to separate poultry from humans and a series oftraffic and logistics (后勤) measures will be discussed at the Legislative Council's Food Safety and Environmental Hygiene Panel meeting next month. Secretary for Health, Welfare and Food Dr York Chow says the contingency plan would come into force if an outbreak occurred near Hong Kong.
Speaking on a radio talk show this morning, Dr Chow said the separation of poultry from humans policy, which will be determined after a decision whether to set up a central slaughtering (屠宰) house or several regional ones,would be based on thedemand for live chickens.
He pointed out that at present therewere 30,000 live chickens imported from the Mainland and 30,000 supplied locally. If this demand persisted, therewould beno central slaughtering house or wholesale point that could handle such an amount and regional slaughtering housescouldbe the choice.
He added that building of regional slaughtering houses took time, but stressed the need to study the views of the public and the sector before a final decisionwas made.
Regarding avian flu vaccination (种痘) for humans, Dr Chow said itwas still being developed.He added that it may not be reliable in the case of an outbreak as records show vaccination can only offer 5% protection against a virus.
He said Hong Kong had more experience and expertise than neighbouring territories in the fight against viral outbreaks, andwas willing to offer them help.He addedtherewas no “boundary” for infectious diseases and close cooperation among different countries had to be maintained to fight against a possible outbreak.It can be inferred from the first paragraph that ______.
| A．the government is planning to take strong action to fight against bird flu |
| B．an outbreak which happened near Hong Kong made people very frightened |
| C．anti-bird flu contingency measures will come into use next month |
| D．Dr York Chow will organize a meeting to discuss the contingency plan |
According to the passage, the best way to fight against bird flu is to ______.
| A．separate poultry from humans | B．set up a central slaughtering house |
| C．set up several regional slaughtering houses | D．get avian flu vaccination |
When the final decision will be made mainly depends on ______.
| A．the demand for live chickens | B．the views of the public |
| C．the advice from experts | |
| D．the time when regional slaughtering houses will be finished |
Which of the following statements isn’t Dr York Chow’s opinion?
| A．Hong Kong is better at dealing with viral outbreaks than its neighbours. |
| B．Infectious diseases could happen in any country. |
| C．Other territories should ask Hong Kong for help because it has more experience. |
| D．Cooperation is quite necessary when danger is coming. |
A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces (熔炉) that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.
The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.
After the explosion gravity pulls in what’s left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.
The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!
That’s what we know about black holes. What we don’t know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.
But if the black hole doesn’t keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly—somewhere else. But where? A different place, perhaps, or a different time — many years in the past or future.
Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed. So far the time being, black hole must remain a mystery.
Black holes are a mystery—but that hasn’t stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth’s energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste—a sort of huge waste disposal(处理) in the sky!When the star begins to die ______.
| A．there is no fuel left in it | B．its outer layer goes into space first |
| C．a huge explosion will happen | D．it doesn’t give off light any longer |
Which of the following doesn’t help produce a black hole?
| A．The gravity inside the star is very strong. | B．The light can’t go out of the star. |
| C．The star becomes smaller and smaller | D．The dying star shines very brightly. |
The black hole ______.
| A．continues becoming smaller and smaller all the time |
| B．goes into another universe and becomes a white hole |
| C．can pull in everything we know of in the world |
| D．will appear at another place at a different time |
What’s the best title for this passage?
| A．A New Scientific Discovery: Black Holes |
| B．How Do Black Holes Come Into Being? |
| C．What Are Black Holes? |
| D．Travel Through A Black Hole |
