我算達人嗎
Earlier this year, bird flu panic was in full swing: The French feared for their foie gras, the Swiss locked their chickens indoors, and Americans enlisted prison inmates in Alaska to help spot infected wild birds.
The H5N1 virus - previously confined to Southeast Asia - was striking birds in places as diverse as Germany, Egypt, and Nigeria, and a flu pandemic seemed inevitable.
Then the virus went quiet. Except for a steady stream of human cases in Indonesia, the current flu epicenter, the past year's worries about a catastrophic global outbreak largely disappeared.
What happened?
Part of the explanation may be seasonal. Bird flu tends to be most active in the colder months, as the virus survives longer at low temperatures.
"Many of us are holding our breath to see what happens in the winter," said Dr. Malik Peiris, a microbiology professor at Hong Kong University. "H5N1 spread very rapidly last year," Peiris said. "So the question is, was that a one-off incident?"
Some experts suspect poultry vaccination has, paradoxically, complicated detection. Vaccination reces the amount of virus circulating, but low levels of the virus may still be causing outbreaks - without the obvious signs of dying birds.
"It's now harder to spot what's happening with the flu in animals and humans," said Dr. Angus Nicoll, influenza director at the European Centres for Disease Control and Prevention.
While the pandemic has not materialized, experts say it's too early to relax.
"We have a visible risk in front of us," said Dr. Keiji Fukuda, coordinator of the World Health Organization's global influenza program. But although the virus could mutate into a pandemic strain, Fukuda points out that it might go the other direction instead, becoming less dangerous for humans.
H5N1 has primarily stalked Asia. This year, however, it crossed the continental divide, infecting people in Turkey, Iraq, Egypt, Djibouti, and Azerjan.
But despite the deaths of 154 people, and hundreds of millions of birds worldwide dying or being slaughtered, the virus still has not learned how to infect humans easily.
Flu viruses constantly evolve, so the mere appearance of mutations is not enough to raise alarm. The key is to identify which mutations are the most worrisome.
"We don't really know how many changes this virus has got to make to adapt to humans, if it can at all," said Dr. Richard Webby, a bird flu expert at St. Jude Children's Research Hospital in Tennessee.
The most obvious sign that a pandemic may be under way will almost certainly come from the field: a sudden spike in cases suggesting human-to-human transmission. The last pandemic struck in 1968 - when bird flu combined with a human strain and went on to kill 1 million people worldwide.
In May, on Sumatra island in Indonesia, a cluster of eight cases was identified, six of whom died. The World Health Organization immediately dispatched a team to investigate.
The U.N. agency was concerned enough by the reports to put pharmaceuticals company Roche Holding AG on standby in case its global antiviral stockpile, promised to WHO for any operation to quash an emerging pandemic, needed to be rushed to Indonesia.
Luckily, the Sumatra cluster was confined to a single family. Though human-to-human transmission occurred - as it has in a handful of other cases - the virus did not adapt enough to become easily infectious.
This highlighted many of the problems that continue to plague public health officials, namely, patchy surveillance systems and limited virus information.
Even in China, where H5N1 has circulated the longest, surveillance is not ideal.
"Monitoring the 14 billion birds in China, especially when most of them are in back yards, is an enormous challenge," said Dr. Henk Bekedam, WHO's top official in China. Of the 21 human cases China has logged so far, 20 were in areas without reported H5N1 outbreaks in birds.
"We need to start looking harder for where the virus is hiding," Bekedam said.
To better understand the virus' activity, it would help to have more virus samples from every H5N1-affected country. But public health authorities are at the mercy of governments and academics. Scientists may hoard viruses while waiting for academic papers to be published first. And developing countries may be wary of sharing virus samples if the vaccines that might be developed from them might ultimately be unaffordable.
That leaves public health officials with an incomplete viral picture.
"It shouldn't just be WHO as a lonely voice in the desert, calling for more viruses (to be shared)," said Dr. Jeff Gilbert, a bird flu expert with the Food and Agriculture Organization in Vietnam. All countries, need to understand that sharing will help them better prepare for a flu pandemic, he said.
Though scientists are bracing themselves for increased bird flu activity in the winter, there are no predictions about where it might appear next. The WHO's Fukuda said it would not be a surprise to see it appear in new countries.

㈥ 考博英語作文要符合哪些特性
考博英語是很多已經參加過考博考試的學員公認的比較難的一個科目，特別是考博英語作文更是無從下筆，但也有不少考博考生寫出了很多不錯的英文文章。這就要求考生在寫作時文章要內容切題，表達清楚，意思連貫，語言比較規范。那麼，考博英語作文要符合哪些特性呢？
考博英語作文要符合的特性一，文章統一性。
想要寫好一篇文章，考生首先要做到的就是切題，而實際上就是要求考博文章統一性。所謂統一性，就是指考博英語短文必須圍繞著主題擴展，不能多中心。考博英語作文統一性表現在句子、段落、篇章三個方面。
考博英語作文要符合的特性二，文章連貫性。
文章的連貫性指句子與句子之間、段落與段落之間的銜接要能夠顯得自然通暢，主要體現在文章的邏輯發展順序和過渡詞語的運用上。在邏輯順序上，按照時間先後，或空間位置的相互關系，考生可以寫出眉目清晰、符合邏輯的段落或文章。敘述文體多採用時間順序，描寫文體中空間順序更常見。有時，單靠邏輯上的連貫對英語來說是很不夠的，因而過渡詞語的運用必不可少。漢語的連貫屬於"意合"，英語的連貫屬"形合"，而藉助過渡詞語取得語篇的連貫是形合法最突出的特點。
考博英語作文要符合的特性三，文章規范性。
考博英語作文語言的規范涉及面廣。小至遣詞造句，大到文章結構，無不體現語言使用的質量。因此要多讀多看英語報刊和原著，從中學習語言用法，沒有仔細閱讀過、理解過的東西千萬不要在作文中使用，切忌中國式英語。
㈦ 2018年上海交通大學考博英語作文題目是什麼

其大作文題目為：大學是硬體重要還是有名學者重要？

作文字數要求為：300字左右。
由於所有內容由考生提供，因此與正式的考題有所出入，但基本相差不大。現由華慧考博為各位考生整理公布，以供將來的博士生考生們復習參考！
㈧ 中國石油大學考博經驗：考博英語作文該怎樣
有的考生一味追抄求文章的完美而千篇一律地用結構復雜的句型，從而使得文章變的過於華麗反而顯得冗長拖沓，就像是文言文般的「咬文嚼字」，讓評卷教師感到「不太舒服」從而影響作文的得分，適得其反。長句短句各有千秋，簡單句復合句也是各有特色：長句能夠增加要點的內涵，使得句子「枝繁葉茂」，但使用不當會有失精準，運用起來不夠靈活；不失時機地插入短句，會讓文章長短有致，既達到了結構上的要求，有符合表達意義上的要求
