    A person's chances of falling ill from a new strain (菌株) of flu are at least partly determined by the first strain they ever met with, a study suggests.

    Research in Science Journal looked at the 18 strains of influenza A ( 甲型流感) and the hemagglutinin protein (红血球凝集素蛋白) on its surface. They say there are only two types of this protein and people are protected from the one their body meets first, but at risk from the other one. A UK expert said that could explain different patterns in flu pandemics (流行病).The researchers, from University of Arizona in Tucson and the University of California, Los Angeles, suggest their findings could explain why some flu outbreaks cause more deaths and serious illnesses in younger people. The first time a person's immune system meets a flu virus, it makes antibodies targeting hemagglutinin protein that sticks out of the surface of the virus — like a lollipop (棒棒糖).

    Even though there are 18 types of influenza A, there are only two versions of hemagglutinin. The researchers, led by Dr Michael Worobey, classed them as "blue" and "orange" lollipops. They said people born before the late 1960s were exposed to "blue lollipop" flu viruses — H1 or H2 — as children. In later life they rarely fell ill from another "blue lollipop" flu — H5N1 bird flu, but they died from "orange" H7N9. Those born in the late 1960s and exposed to "orange lollipop" flu — H3 — have the opposite pattern.

    His team looked at cases of H5N1 and H7N9 — two kinds of bird flu which have affected hundreds of people, but have not developed into pandemics. The researchers found a 75% protection rate against severe disease and 80% protection rate against death if patients had been exposed to a virus with the same protein version when they were children.

    Dr Worobey said the finding could explain the unusual effect of the 1918 "Spanish flu" pandemic, which was more deadly among young adults. "Those young adults were killed by an H1 virus and from blood analysed many decades later there is a pretty strong indication that those individuals had been exposed to a mismatched H3 as children and were therefore not protected against H1. The fact that we are seeing exactly the  same pattern with current H5N1 and H7N9 cases suggests that the same fundamental processes may govern both the historic 1918 pandemic and today's contenders (斗争者) for the next big flu pandemic."

    Jonathan Ball, professor of University of Nottingham, said, "This is a really neat piece of work and provides a reason why human populations have been sensitive to different strains of bird influenza over the past 100 years or so. The findings are based on analysis of patient records and they certainly need further proof in the laboratory, but nonetheless the results are pretty amazing and inspiring."

(1)、The findings, if proved, will help people      .
A、protect themselves from flu attacks B、analyze more clearly the records of a patient infected with a bird flu C、find out who are easier to get infected with a bird flu than others D、find new drugs to cure patients of flu infections
(2)、The researchers use "blue lollipop" and "orange lollipop" for two versions of hemagglutinin in order to produce                 .
A、a good visual effect B、a good logic effect C、an effect of being abstract D、an effect of being clear
(3)、While what Dr Worobey said is focused on the facts, Jonathan Ball's remarks on the research are focused on                 .
A、the popularity of the research B、challenges and current situation C、summary and future plans D、evaluation and influences
(4)、What can serve as the best title of this passage?
A、Cure for Bird Flu Not Far Away B、First Flu Affects Lifetime Risk C、New Classification of Flu Pandemics D、How Bird Flu Affects People
举一反三
阅读下列短文,从每题所给的A、B、C、D四个选项中,选出最佳选项。

        Every man wants his son to be somewhat of a clone, not in features but in footsteps. As he grows you also age, and your ambitions become more unachievable. You begin to realize that your boy, in your footsteps, could probably accomplish what you hoped for. But footsteps can be muddied and they can go off in different directions.

My son Jody has hated school since day one in kindergarten. Science projects waited until the last moment. Book reports weren't written until the final threat.

I've been a newspaperman all my adult life. My daughter is a university graduate working toward her master's degree in English. But Jody? When he entered the tenth grade he became a “vo-tech” student(技校学生). They're called “motorheads” by the rest of the student body.

When a secretary in my office first called him “motorhead”, I was shocked. “Hey, he's a good kid,” I wanted to say. “And smart, really.”

I learned later that motorheads are, indeed, different. They usually have dirty hands and wear dirty work clothes. And they don't often make school honor rolls(光荣榜).

But being the parent of a motorhead is itself an experience in education. We who labor in clean shirts in offices don't have the abilities that motorheads have. I began to learn this when I had my car crashed. The cost to repair it was estimated at $800. “Hey, I can fix it,” said Jody. I doubted it, but let him go ahead, for I had nothing to lose.

      My son, with other motorheads, fixed the car. They got parts(零件)from a junkyard, non-toasting toaster have been fixed. Neighbours and co-workers trust their car repair to him.a

        Since that first repair job, a broken air-conditioner, a non-functioning washer and a non-toasting toaster have been fixed. Neighbors and co-workers trust their car repairs to him.

        These kids are happiest when doing repairs. They joke and laugh and are living in their own relaxed world. And their minds are bright despite their dirty hands and clothes.

I have learned a lot from my motorhead: publishers need printers, engineers need mechanics, and architects need builders. Most important, I have learned that fathers don't need clones in footsteps or anywhere else.

        My son may never make the school honor roll. But he made mine.

    What might the future be like? Here are some predictions: things to come, things to go.

    Spring Festival, the most important Chinese holiday when everyone returns home has caused headaches for millions of Chinese. More than 2 billion people travel at the same time, making getting travel tickets and the journey difficult. But in 28 years, Spring Festival travel may not be a problem at all. China plans to build more than 120,000 kilometers of railway and a fast transportation network that will serve 90% of the population by 2020.

    And because most of China will be cities, people will not have to go to other places to find a job, so it will no longer be a problem.

Newspapers will come to an end in 2043. In the future, digital newspapers will be sent to personal web tools through Internet. Readers can discuss topics with journalists and editors. Information will move faster.

    Oil is running out faster than expected. But scientists have found something else for oil as fuel. Coal, natural gas, solar power, nuclear power and even water can take the place of oil as sources of energy.

    Schools will go electronic. Computers will be important and popular among the students. Everything will be in the computer and students will not need to bring books to school. They will find information on the Internet. A computer will be the students ‘library, schoolbag and connection to the outside world. There will be robot teachers, who will check homework on computers and communicate with the students' parents through e-mail. And school buses will be like spaceships, comfortable and safe.

    What will man be like in the future—in 5000 or even 50,000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time.

    Let us take an obvious example, Man, even five hundred years ago, was shorter than he is today. Now, on averse, men are about three inches taller. Five hundred years is a relatively short period of time, so we may assume that man will continue to grow taller. Again, in the modem world we use our brains a great deal. Even so, we still make use of only about 20% of the brain's capacity. As time goes on, however, we shall have to use our brains more and more, and eventually we shall need larger ones! This is likely to bring about a physical change too: the head, in particular the forehead, will grow larger. Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man's eyes will grow stronger.

    On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they an; a great deal in modem life.

    But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald (光秃的).

    Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. But in spite of all these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and emotions similar to our own.

    One of the greatest sources of unhappiness, in my experience, is the difficulty we have in accepting things as they are.

    When we see something we don't like, we wish it could be different. We cry out for something better. That may be human nature, or perhaps it's something ingrained(根深蒂固的) in our culture. The root of the unhappiness isn't necessarily that we want things to be different. However, it's that we decided we didn't like it in the first place. We've judged it as bad, rather than saying, "It's not bad or good, and it just is it."

    In one of my books, I said "You should expect people to mess up and expect things to go differently than you planned". Some readers said it's too sorrowful to expect things to go wrong. However, it's only negative if you see it as negative and judge it as bad. Instead, you could accept it as the way the world works and try to understand why that is.

    This can be applied to whatever you do: how other people act at work, how politics works and how depressing the news media can be. Accept these things as they are, and try to understand why they're that way. It will save you a lot of sadness, because you'll no longer say, "Oh. I wish bad things didn't happen!"

    Does it mean you can never change things? Not at all. But change things not because you can't accept things as they are, but because you enjoy the process of changing, learning and growing.

    Can we make this world a better place? You can say that you'll continue to try to do things to help others, to grow as a person, to make a difference in this world. That's the correct path you choose to take, because you enjoy that path. Therefore, when you find yourself judging and wishing for difference, try a different approach: accept, and understand. It might lead to some interesting results.
