Grown-ups know that people and objects are solid. At the movies, we know that if we reach out to touch Tom Cruise, all we will feel is air. But does a baby have this understanding?
To see whether babies know objects are solid, T. Bower designed a method for projecting an optical illusion（视觉影像） of a hanging ball. His plan was to first give babies a real ball, one they could reach out and touch, and then to show them the illusion. If they knew that objects are solid and they reached out for the illusion and found empty air, they could be expected to show surprise in their faces and movements. All the 16-to 24- week -old babies tested were surprised when they reached for the illusion and found that the ball was not there.
Grown-ups also have a sense of object permanence. We know that if we put a box in a room and lock the door, the box will still be there when we come back. But does a baby realize that a ball that rolls under a chair does not disappear and go to never-never land?
Experiments done by Bower suggest that babies develop a sense of object permanence when they are about 18 weeks old. In his experiments, Bower used a toy train that went behind a screen. When 16-week-old and 22-week-old babies watched the toy train disappear behind the left side of the screen, they looked to the right, expecting it to reappear. If the experimenter took the train off the table and lifted the screen, all the babies seemed surprised not to see the train. This seems to show that all the babies had a sense of object permanence. But the second part of the experiment showed that this was not really the case. The researcher substituted a ball for the train when it went behind the screen. The 22-week-old babies seemed surprised and looked back to the left side for the train. But the 16-week -old babies did not seem to notice the switch. Thus, the 16-week-old babies seemed to have a sense of “something permanence,” while the 22-week-old babies had a sense of object permanence related to a particular object. The passage is mainly about _____.
| A．babies' sense of sight | B．effects of experiments on babies |

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 |
BEIJING, Nov. 26—U.S. dollar hit another record low against the euro on Friday, with the European currency climbing above $1.32 for the first time. The green-backfellto itslowest in nearly five years against the yen the same day.

The British National Health Service (NHS) was set up in 1948 and was designed to provide equal basic health care, free of charge, for everybody in the country. Before this time health care had to be paid for by individuals.
Nowadays central government is directly responsible for the NHS although it is administered by local health authorities. About 83 percent of the cost of the health service is paid for by general taxation and the rest is met from the National Insurance contributions paid by those in work. There are charges for prescription and dental care but many people, such as children, pregnant women, pensioners, and those on Income Support, are exempt from payment.
Most people are registered with a local doctor (a GP, or General Practitioner) who is increasingly likely to be part of a health centre which serves the community.
As the population of Britain gets older, the hospital service now treats more patients than before, although patients spend less time in hospital. NHS hospitals—many of which were built in the nineteenth century—provide nearly half a million beds and have over 480, 000 medical staff. The NHS is the biggest employer in Europe although Britain actually spends less per person on health care than most of her European neighbours.
During the 1980s there was considerable restructuring of the Health Service with an increased emphasis on managerial efficiency and the privatization of some services (for example, cleaning). At the end of the 1980s the government introduced proposals for further reform of the NHS, including allowing some hospitals to be self-governing, and encouraging GPs to compete for patients. Patients would be able to choose and change their family doctor more easily and GPs would have more financial responsibility. The political questions continue of how much money should be provided to support the NHS and where it should come from. We can know from the first paragraph that ______.
| A．the original aim of the NHS was to provide equal basic health care for everybody |
| B．people didn’t have to pay for health care since the NHS was set up |
| C．patients were charged for receiving health care before 1948 |
| D．the NHS was an organization which gave free advice to villagers |
What do we know about the NHS?
| A．It’s managed by the central government. |
| B．Its cost is mainly paid for by the National Insurance contributions. |
| C．It hires more people than any other unit in Europe. |
| D．Fewer patients go to its hospitals than before because they spend less on health care. |
All the following statements about GPs are true except that they ______.
| A．take care of the local people’s health |
| B．often take part in competitions to see who is the best |
| C．work under high pressure nowadays |
| D．have more responsibilities than before |
What does the underlined word “exempt” probably mean?
| A．suffering | B．different | C．prevented | D．free |
The biggest problem for the NHS is ______.
| A．many hospitals are too old to be used |
| B．some services are in the charge of individuals |
| C．more and more patients go to GPs for treatment |
| D．there is not enough money for further reform |
