Who are these people rushing by you on the street? More than 250 million people now call Amer??ica" home" , but most of them can trace their families back to other parts of the world. If you, look at the names on shop windows, you will see that Americans come from many different lands. The idea that these people, who once were strangers to the United States，have lost the customs and cultures of their original countries and have become "Americans"is really not true. In fact, what exists in Ameri??ca is - more often a kind of “ side - by - side" living in which groups of people from other countries often have kept many of their own customs and habits. They join the general American society only in certain areas of their lives such as in schools，business，and sports一but they keep many of their own native customs and manners socially and at home. This “ side - by - side" living has both advantages and disadvantages. Sometimes it may cause disagreements to develop between groups whose ways of life are very different from one another. However, there are also great advantages that come from the variety of cultures brought by settlers from other lands. There is great freedom of choice among ideas ’ dress, food, and social customs in America. Everyone can find some part of his or her own familiar world in the United States, in churches, music, food, national groups, or newspaper.

A long-awaited final report from the Food and Drug Administration (FDA) concludes that foods from healthy cloned animals and their offspring(后代) are as safe as those from ordinary animals, effectively removing the last US regulatory(监管的) barrier to the marketing of meat and milk from cloned cattle, pigs and goats.
The 968-page final report, not yet released but obtained by The Washington Post, finds no evidence to support people’s concerns that food from clones may have hidden risks.
But, recognizing that a majority of consumers are wary of food from clones—and that cloning could damage the good image of American milk and meat—the report includes hundreds of pages of raw(原始的) data so that others can see how it came to its conclusions.
The report also admits that human health concerns are not the only subject raised by the coming-out of cloned farm animals.
“Moral, religious and ethical concerns have been raised,” the agency notes in a document accompanying the report. But the report is “exactly a science-based evaluation.” It reports, because the agency is not authorized by law to consider those subjects.
In practice, it will be years before foods from clones make their way to store shelves in large quantities, in part because the clones themselves are too valuable to kill for meat or milk. Instead, the expensive animals—replicas(复制品) of some of the finest farm animals ever born—will be used firstly as breeding stock to create what supporters say will be a new generation of superior farm animals.
When food from those animals hits the market, the public may yet have its say. FDA officials have said they do not expect to require food from clones to be labeled as such, but they may allow foods from ordinary animals to be labeled as not from clones.
64.   What can we infer from the first paragraph?
A.    FDA has waited for a long time to get this final report.
B.    Products from cloned animals have been put into the market before.
C.    People are having the products from cloned animals safely.
D.    There have been once opposite opinions against cloned products.
65.   What does the underlined word “wary” mean?
A. Disappointed.           B. Careful.         C. Fond.                                 D. Proud.
66.   It will be a few years before foods from clones come into the market, partly because _____.
A.    people have little knowledge of the cloned animals
B.    supporters can’t give powerful evidence to support that
C.    the few cloned animals will first be used to create superior animals
D.    they are a new generation for the customers and are too valuable for the customers
67.   What can we conclude from the passage?
A.    FDA officials encourage people to eat more food from clones.
B.    FDA officials think the food from clones will sell better than ordinary food.
C.    People only worry about the health problems when it comes to foods from the clones.
D.    All the foods will not have detailed labels on them.

If you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of out brains are not getting enough exercise, and as a result, we are growing old unnecessarily soon.
Professor Taiju Matsuzawa wanted to find out why quite healthy farmers in northern Japan appeared to be losing their ability to think and reason at a rather early age, and how the speed of getting old could be slowed down.
With a team of researchers at Tokyo National University, he set about measuring brain sizes of a thousand people of different ages with different jobs.
Computer technology helped the researchers to get most exact measurements of the sizes of the front and side parts of the brain, which have something to do with thinking and feeling, and decide the human character. As we all know, the back part of the brain, which controls task like eating and breathing, does not contract(萎缩) with age.
Contraction of front and side parts, as cells(细胞) die off, was seen in some people in their thirties, but it was still not found in some sixty and seventy-year-olds.
Matsuzawa concluded from his tests that there is a simple way to prevent the contraction---using the head.
The findings show that contraction of the brain begins sooner in people in the country than those in the towns. Those with least possibility, says Matsuzawa, are lawyers, followed by university professors and doctors. White-collar workers doing the same work day after day in government offices are, however, as possible to have contracting brains as the farm workers, bus drivers and shop assistants.
