If we were asked exactly what we were doing a year ago,we should probably have to say that we could not remember. But if we had kept a book and had written in it an account of what we did each dav.we should be able to give an answer to the question.

It 1s the same in history.Many things have been forgotten because we do not have any written account of them. Sometimes men did keep a record of the most important happenings in their country.but often it was destroyed by fire or in a war.Sometimes there was never any written record at all because the people of that time and place did not know how to write.For example,we know a good deal about the people who lived in China 4,000 years ago,because they could write and leave written records for those who lived after them.But we know almost nothing about the people who lived even 200 years ago in Central Africa,because they had not learned to write.

Sometimes,of coures,even if the people cannot write,they may know something of the past.They have heard about it from older people,and often songs, dances and stories have been made about the most important happenings, and these have been sung,acted and told for many generations,for most people are proud to tell what their fathers did in the past.This we may call”remembered history”.Some of it had been written down. If is not so exact or so valuable to us as written history,is,because words are much more easily changed when used again and again in speech than when copied in writing.But where there are no written records,such spoken stories are often very helpful.

Which of the following is not mentioned in the passage?

A.“Remembered history”,compared with written history.is 1ess reliable.

B. Written records of the past play a most important role in our learning the human history.

C. A written account of our daily activities helps us to remember the events that happened in the past.

D.Where there are no written records of the past.there is no history.

Why do we know little about what happened in Central Africa 200 years ago?

A.There was nothing worth being written down at that time.

B.People there had not known how to write in those days.

C.The written records were perhaps destroyed in a fire.

D.People there ignored the importance of keeping a record.

”Remembered history”is regarded as valuable only when      .

A.it is written down       B.it proves to be true

C.no written account is available  D.people are interested in it

It can be inferred from the passage that we could have learned much more about our past than we do now if our ancestors had    .

A.kept a written record of every past event

B.not burnt their written records in wars

C.told exact stories of the most important happenings

Since the gene , called DAF-16 in worms, was found in many animals and in humans, the finding could open up new ways to affect aging ,immunity and resistance in humans the scientists said.
“We wanted to find out how normal aging is being governed by genes and what effect these genes have on other traits such as immunity,”said Robin May , who led the study.
Populations across the world are aging at a surprising pace , bring potentially big challenges for health and social care systems . A study by Danish scientists last year found that half of babies born in rich world today will live to celebrate their 100th birthday . Scientists are eager to find out how people age to try to develop drugs to help them stay healthier lives extend.
“What we have found is that things like resistance and aging tend go hand in hang “ May said in an interview
May’s team compared longevity ,stress resistance and immunity in four related species of worm. They also looked for differences in the activity of DAV-16 in each of the four species and found that they were all quite distinct.
May said DAF-16 was active in most cells in the body and was very similar to a group of human genes called FOXO genes , which scientists believe play a role in the aging process. “The fact that subtle differences in DAF-16 between species seem to have such an impact on aging and health is very interesting and many explain how differences in lifespan and related traits have arisen during evolution,”May said
【小題1】In which section may the text appear in a newspaper?
A  Education   B  Science   C  Entertainment    D  Culture
【小題2】 According to May ,   
A resistance has a lot of to do with aging    B FOXO genes can be found in worms
C genes play the same role in difference species   D  new drugs will change the genes in older people
【小題3】From the text we know that DAF-16   
A is a gene that is only found in worms     B can make people live longer

Do you know some people who just have all the luck? They seem to get all the       and you ask yourself: “Why don’t I get    ? Why don’t I get a great education?” But the real reason why most people are successful or lucky is that they’ve learned how to       themselves in a place so they can be lucky. They’ve learned how to, in a way,       their own luck!

I’m not       about dishonest or illegal ways. I’m talking about hard,       work. But successful people work smart. They keep improving and making the most of their abilities. Yet they also learn to      for help in things they themselves are not that good       doing. So we not only must make the most of our own special strengths, we must also learn our       and weaknesses.

A man recently got his lucky big break. Everyone said, “That guy’s so lucky!” But that man created his own luck       by arriving at the office early. He apologized and       when he was wrong. He even shared the credit and reward with others       he had done much of the work. He was never satisfied just to get       and do average work. He always       the extra effort to do his very best.

We have to work hard and do what it       to be on the way to luck and success when it comes.        , weMI miss it because we aren’t ready. You never know when the right opportunity will come your way, and when the right, important person is watching your excellent        and work. That’s when you’ll get your lucky break! But when you put your life in Jesus Christ’s         , the right important person is always         you and all that you do. Then he will       and bless vour life in manv wavs as vou do vour very best to please him in every thina every dav.
