Heres how it works.Viruses, which cause pandemics, have two important proteins haemagglutinin(H) and neuraminidase(N).H helps the virus go into a cell .N helps new virus break out of that cell .They are parts of a virus that may be known and dealt with by the immune systemA flu virus attacks a host cell in order to reproduce itself. But the virus created out of it is quite different now. The viruss genetic material is copied with low fidelity. That difference produces virus which immune system does not always know and deal with immediately. Each years seasonal virus is therefore a little bit different, and thus requires an updated vaccine to prevent people from getting that disease.Pandemics viruses have bigger changes in this process .Many hosts defences are unprepared for such big changes, which happen three or four times a century .The 1918 pandemics was caused by viruses carrying H1 and N1.Anotber two pandemics in 1957 and 1968 were caused by viruses carrying H2and H3 together with N2.They are numbered by scientists. Much of this change goes on outside humans. A flu is usually from sick binds. Sometimes a bird-flu appears with materiel that enable it to spread among people .The H7N9 is recently worrying scientists in the health center.The flu virus sometimes jumps directly from a bird(often a chicken) to a person, but more usually passes through a pig The cells in bird and human are built differently, It means us that the virus needs different sets of material to attack them .Pig cells have features of both so that it can act as a platform in which the virus can fit from one to the other .Even after it has made humans ill, a virus cannot go ca to cause a pandemic unless it also gets the ability to pus easily between people, Luckily, this is something H7N9 has yet to do.（1）The underlined ward pandemics in the first paragraph probably is .A . a virus from pigs and chickenB . an animal carrying flu virusesC . a disease passing easily aroundD . a race inside human body（2）Paragraph 2 is mainly about .A . the harm of viruses.B . the spread of viruses C . the cause of virusesD . the structure of viruses（3）What can we learn from the passage? A . H7N9 can move from person to person easily nowB . Flu viruses develop both inside and outside humans.C . Pandemics viruses change very often during a short time.D . Immune system can always keep flu viruses away immediately（4）What is the best title of the passage? A . A Serious Disease Worrying ScientistsB . A New Effective Way to Prevent VirusesC . Changeable viruses Mind your H and ND . The Important Function of Immune System3. （8分） According to scientists research, the month in which babies are born could affect them in some ways.Babies born in spring get sick easily. Children born under Aquarius may be less clever than those born in other seasons. They may also have shorter lives than those born in autumn Scientists believe many of the differences can be explained by the mothers exposure to sunlight in pregnancy(怀孕). Sunlight helps lead to the production of Vitamin D in the body. The lack of this in the first months of life may have a bad effect on mental and physical health.Vitamin D, called the sunshine vitamin, is known to help regulate（调节） thousands of genes during development, according to a study of more than two million people. So Vitamin D has a good effect on health This study showed that people born from April to June had slightly shorter lives than those born in October, November or December. Similar studies in the USA showed that people born in autumn lived about 160 days longer than those born in spring.Professor Russell Foster, an Oxford University neuroscientist on seasonal biology, said the conclusions were surprising and interesting. He added, These are small effects but they are very, very clear. I am not giving voice to star signs and they are just for fun. But it is true that we are affected by our season of birth.（1）A babys season of birth doesnt affect its_.A . healthB . heightC . length of lifeD . mind（2）According to the passage,_ can help people get Vitamin D.A . enough sleepB . enough sunlightC . fresh air D . suitable seasons（3）Which of the following is TRUE according to the passage?A . People born in spring may not be in good health.B . Children born under Aquarius are cleverer than those born under Libra.C . Professor Russell Foster is interested in star signs and believes in themD . People born in May will live longer than those born in October.（4）What does the passage mainly tell us?A . People can know the length of life by star sign.B . Women should choose to give birth to children in spring.C . A childs season of birth has some effect on him or her.D . Vitamin D is very important to peoples health.二、 根据首字母、中文提示填空 (共8题；共8分)4. （1分）Hearing someone came in, my younger sister hid h_ behind the door. 5. （1分）My new t_number is 212-7188. 6. （1分）Its _(not interesting) for me to stay at home all day long. 7. （1分）A_ is my favorite season. 8. （1分）When I am sad, my friend Annie always tells me funny_（笑话）. 9. （1分）The teacher is writing with a piece of white c_.10. （1分）Sue has a new_（夹克）.
