I happened to read in the paper about your summer camp a couple of days ago, which is why I’m now writing to you to present myself for the camp.
There is a joke among flu researchers: “If you've seen one flu season, you've seen one flu season.” The joke is about the unpredictable nature of the flu virus. Every year it looks different, and every strain (类型) follows its own pattern — it's the reason why new strains like H1N1 are extremely difficult to predict.
Dr. Michael Osterholm is a former adviser to the U.S. Department of Health and Human Services. “I know less about influenza today than I did 10 years ago,” he says in a joking way. “Every stone we've turned over, we get more questions.”
The flu rectums every season and the world experiences terrible pandemics (全国或全世界范围流行的疾病), but researchers still do not understand why some strains infect people and others do not; they are not entirely sure about how the flu is transmitted; nor do they understand why some patients become seriously ill while others develop mild symptoms (症状). As a result, when a new strain shows up — like H1N1 — they often have little information to fall back on, and the lessons of previous pandemics are only somewhat helpful. While researchers are still putting together a complete picture of H1N1, for example, its most striking difference with the seasonal flu is that the elder1y are not the most vulnerable (易受攻击的) population.
Influenza's unpredictable nature makes it a moving target for researchers, says researcher Allison Aiello at the University of Michigan. “Even if we had complete seasonal flu data from the past, it wouldn't be much helpful for a new strain of influenza,” she explains.
Whi1e researchers are frustrated by the holes in their knowledge, they say, however, that the pub1ic--health community is generally doing a very good job responding to H1N1 with seasonal flu data that do exist. Studying influenza, says Osterholm, is “like looking through the windows of a house you can't get into because the door is locked.” Gathering the data researchers do have is like “looking through the windows to get a pretty good picture of what the inside looks like.”
One thing researchers do know for sure: the best way for people to protect against H1N1 is to get the vaccine once it becomes available to them.

Rare birds in the UK have been living far better than the more common birds over the last decade due to the efforts of conservation organisations, according to a new assessment.
The research shows almost 60% of the 63 rare birds that live in the UK have increased over the last 10 years.
By contrast, only about one third of common species have increased over the same period. Just 28% of rare birds have decreased over the same period, compared with four out of every 10 common birds. The rare birds described in the assessment with increasing populations include the osprey (鹗) and corncrake (秧鸡). All of these birds are subject to conservation action.
The declining common birds include the nightingale, swift (雨燕), house sparrow and red grouse (苏格兰雷鸟). These are suffering declines for a variety of reasons, including changes in farming practices.
Dr David Noble, from the British Trust for Ornithology, said: “That some of our rarer birds have responded to targeted conservation action is great news. It shows just what can be achieved. What we need to do now is to continue the good work and use some of the lessons we have learned to help our more common birds.”
Dr Mark Avery, the conservation director of the Royal Society for the Protection of Birds (RSPB), said: “Over the last decade we've enjoyed some great conservation successes, including removing some threatened species from the World Conservation Union's Red List of Thratened Animals and increasing the populations of red kite, osprey, etc. However, these successes are countered (抵消) by continued declines of some widespread species.”
The overview of 210 native birds has been produced by a group of conservation organisations, to mark the publication of The State of the UK's Birds report, which is in its l0th year. The report was published by the RSPB for a group of conservation organisations.

|
D．Half of common birds have decreased in the past ten years in the UK. |
2.We can learn from the passage that Dr David Noble .
|
A．hopes that conservation organisations will change the way they work |
|
B．is quite disappointed with the result of the new assessment |
|
C．is losing confidence in conservation organizations’ action |
|
D．has high hopes for the increase in bird population in Britain |
3. Which of the following can best explain Dr Mark Avery's words?
|
A．The UK should not be satisfied with what they have achieved. |
|
B．The UK should share their experience with other countries. |
|
C．What conservation organisations do is far from satisfactory. |
|
D．The RSPB is responsible for the decrease of common birds. |
4.The passage is most likely to be found in a book about .
|
A．popular science |
B．historical events |
|
C．nature |
D．society |

|
B．the differences between rare birds and common birds |
|
C．the number of rare birds has increased over the last decade |
