The Food and Drug Administration says meat and milk from clones of adult cattle, pigs and goats are safe to eat. An F.D.A. official called them "as safe to eat as the food we eat every day." And when those clones reproduce sexually（有性繁殖）, the agency says, their offspring（后代） are safe to eat as well. But research on cloned sheep is limited. So the F.D.A. proposes that sheep clones not be used for human food.
The United States this year could become the first country to approve the sale of foods from cloned animals. First, however, the public will have ninety days to comment on three proposed documents. On December 28th the F.D.A. released a long report, called a draft risk assessment, along with two policy documents.
The agency says it must receive comments by April second. The F.D.A. seemed ready to act several years ago, but an advisory committee called for more research.
For now, the government will continue to ask producers to honor a request that they not sell foods from cloned animals.
Clones are still rare. They cost a lot and are difficult to produce.
The F.D.A. says most food from cloning is expected to come not from clones themselves, but from their sexually reproduced offspring. It says clones are expected to be used mostly as breeding animals to spread good qualities.
Public opinion studies show most Americans do not like the idea of food from cloned animals. But this research also shows the public knows little about cloning.
Cloning differs from genetic engineering. A cell taken from a so-called donor animals is grown into an embryo（胚胎）in the laboratory. Next, the embryo is placed into the uterus（子宫）of a female animal. If the process is successful, the pregnancy reaches full term and a genetic copy of the donor animal is born.

As time went by, these small family clans joined with others to form larger groups for protection. Joining with other clans gave them more hunters and more women to help cut up the meat and share it between families. Eventually, people tamed(驯养)wild animals such as dogs and horses. People settled around rivers and fertile plains to share responsibilities and duties. Then, people began to plant crops instead of moving to areas where the plants grew. This development changed the environment.
Traditional forms of work also changed. Some people were better at performing a particular task than other clan members, so then began to specialize in things they were good at doing. This also meant that they began to exchange their goods for things that others produced.
People began to communicate with distant tribes. Land was cleared for roads. Foreign plants and animals were transported to places where they had not existed before. Specialization also give people more free time. So art ,dance and music became important ways of expressing feelings and thoughts. This was how many great civilizations started.
Compared to the past, modern civilization has experienced many changes to become the highly developed society that exists today. Populations have increased rapidly. Forests have been cleared for farms. Inventions and technology have made work easier.
However, pollution and other serious problems have also resulted from human progress. As concerned citizens, it is up to us to learn from past mistakes and to help maintain and improve our environment.
小题1:Early tribes didn’t have much effect on animal population because_____
A .they kept animals for themselves B they ate only vegetables
C they loved animals D they killed only enough for food
小题2:The main purpose for small clans to join together was_____
A to hurt animals B to seek safety
C to share caves D to protect environment
小题3:According to the passage ,we can learn that_____
A early people moved to new places looking for new sources of food
B modern civilization began when people started to live together in big groups
C modern advancements are always good for the environment
D people began to exchange goods because they didn’t have enough money
小题4:It can be concluded from the passage that_____
A human progress has brought civilization to the society
B civilization has improved traditional forms of work
C early people understood environmental protection
D our environment has been affected by human progress
The first caves discovered beyond the Earth appear as seven mysterious black dots on the pictures sent back by NASA’s Mars Odyssey orbiter. Each as large as a football field, they may be openings into natural caves below the Martian surface.
“If there is life on Mars, there is a good chance you’d find it in caves,” said Jut Wynne, one of the researchers who noticed the features while working on a US Geological Survey Mars Cave Detection Program.
Jonathan Clarke, a geologist with the Mars Society of Australia, yesterday described the discovery as exciting.
One photo taken at night by an infrared imager(红外线成像器) showed one hole to be unusually warm, suggesting hot air trapped during the day is flowing out.
“I said: ‘Wow, that’s a cave’” Dr. Clarke said excitedly. “People have been looking for these for a long time; now we have found them.”
He agreed such caves would be perfect places to hunt for life escaping from the bitterly cold, radiation-soaked(充满辐射的), dry surface.
“Tiny drops of water could collect inside,” he said. “If there are gases coming out, they could provide energy for a whole range of bacteria. A cave is also a protection from radiation; the surface of Mars is exposed to high levels of space radiation.”
The caves probably formed when tube-shaped lave flows(管状岩浆流) spread across the planet long ago. The outside of the tubes cooled, forming solid walls, while something hotter inside allowed the remaining have to flow out, forming caves.
小题1:What does the passage mainly talk about?
| A．How the caves were formed on Mars. | B．How scientists found these caves on Mars. |
| C．Caves on Mars may be full of hot air or a sign of life. | |
| D．Scientists have completely recognized the surface of Mars. |
| A．water has already been found on Mars | B．the scientists found all the caves at night |
| C．it is certain that there is life in these caves | |
| D．the surface of Mars is bitterly cold, radiation-soaked and dry |
| A．such caves could provide energy for life | B．they had finally found the caves on Mars |
| C．such caves would be perfect places to hunt for life | |
| D．scientists had long been looking for these caves |
| A．lava and energy | B．water and radiation from space |
| C．gases and lava | D．water and protection from radiation |
University tuition fees (学费) are currently capped at £3,000 annually, but this will be reviewed next year and the Government is under enormous pressure to raise the ceiling.
In the research, the teenagers were presented with die terms of four different loans but 76 per cent failed to identify the cheapest. The young people also predicted that they would be earning on average £ 31.000 by the age of 25, although the average salary for those aged 22 to 29 is just £ 17,815. The teenagers expected to be in debt when they finished university or training, although half said that they assumed the debts would be less than £ 10.000. Average debts for graduates are £ 12，363.
Stephen Moir, head of community investment at the Royal Bank of Scotland Group which owns NatWest, said. "The more exposed young people are to financial issues, and the younger they become aware of them, the more likely they arc to become responsible, forward-planning adults who manage their finances confidently and effectively."
Ministers are deeply concerned about the financial pressures on teenagers and young people because of student loans and rising housing costs. They have just introduced new lessons in how to manage debts. Nikki Fairweathcr. aged 15. from St Helens, said that she had benefited from lessons on personal finance, but admitted that she still had a lot to learn about money.
1. Which of the following can be found from the five-year research project?
A. Students understand personal finances differently.
B. University tuition fees in England have been rising.
C. Teenagers tend to overestimate their future earnings.
D. The students" payback ability has become a major issue.
2. The phrase "to raise the ceiling" in paragraph 2 probably means "______".
A. to raise the student loans B. to improve the school facilities
C. to increase the upper limit of the tuition D. to lift the school building roofs
3. According to Stephen Moir, students_______.
A. are too young 10 be exposed 10 financial issues
B. should learn 10 manage their finances well
C- should maintain a positive attitude when facing loans
D. benefit a lot from lessons on personal finance
4. What can we learn from the passage?
A. Many British teenagers do not know money matters well
B. Teenagers in Britain are heavily burdened with debts.
C. Financial planning is a required course at college.
D. Young people should become responsible adults.
Around him use. Bit by bit .he makes the necessary changes to make his language like other people"s. In the same way, children learn to do all the other things: they should learn to do without being taught, such as to walk, run, climb, whistle, ride a bicycle—compare their own performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes and correct them for himself. We do it all for him. We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to .Let him work out, with the help of other children if he wants it, what this word says, what the answer is to that problem, whether this is a good way of saying or doing this or not.
If it is a matter of right answer, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such routine（常规）work? Our job should be to help the child when he tells us that he can’t find the way to get the right answer .Let the children learn what all educated persons must some day learn ,how to measure their own understanding, how to know what they know or do not know.
小题1:According to the passage ,the best way for children to learn things is by______
| A．listening to skilled people"s advice |
| B．asking older people many questions. |
| C．making mistakes and having them corrected |
| D．doing what other people do |
| A．Give children correct answers. |

| D．give children more book knowledge |
| A．different from learning other skills |
| B．the same as learning other skills |
| C．more important than other skills |
| D．not really important skills |
A job description should give details of the performance that is required for a particular job, and a job specification should give information about the behaviour, knowledge and skills that are expected of an employee who works in the position. When all of this has been collected, it is possible to make a training specification. This specifies(详细说明) that the training department must teach for the successful performance of the job, and also the best methods to use in the training period.
There are many different training methods, and there are advantages and disadvantages in all of them. Successful training performances depend on an understanding of the difference between learning about skills and training in using them. It is frequently said that learning about skills takes place “off the job” in classroom, but training in using these skills takes place “on the job,” by means of such activities as practice in the workshop.
It’s always difficult to evaluate the costs of a training programme. The success of such a programme depends not only on the methods used but also on the quality of the staff who do the training. A company can often check savings in time and cost by examining the work performed by the workers and technicians who have completed a training programme. The evaluation of management training is much more complex than that.
