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 考博英语作文要符合哪些特性
考博英语是很多已经参加过考博考试的学员公认的比较难的一个科目，特别是考博英语作文更是无从下笔，但也有不少考博考生写出了很多不错的英文文章。这就要求考生在写作时文章要内容切题，表达清楚，意思连贯，语言比较规范。那么，考博英语作文要符合哪些特性呢？
考博英语作文要符合的特性一，文章统一性。
想要写好一篇文章，考生首先要做到的就是切题，而实际上就是要求考博文章统一性。所谓统一性，就是指考博英语短文必须围绕着主题扩展，不能多中心。考博英语作文统一性表现在句子、段落、篇章三个方面。
考博英语作文要符合的特性二，文章连贯性。
文章的连贯性指句子与句子之间、段落与段落之间的衔接要能够显得自然通畅，主要体现在文章的逻辑发展顺序和过渡词语的运用上。在逻辑顺序上，按照时间先后，或空间位置的相互关系，考生可以写出眉目清晰、符合逻辑的段落或文章。叙述文体多采用时间顺序，描写文体中空间顺序更常见。有时，单靠逻辑上的连贯对英语来说是很不够的，因而过渡词语的运用必不可少。汉语的连贯属于"意合"，英语的连贯属"形合"，而借助过渡词语取得语篇的连贯是形合法最突出的特点。
考博英语作文要符合的特性三，文章规范性。
考博英语作文语言的规范涉及面广。小至遣词造句，大到文章结构，无不体现语言使用的质量。因此要多读多看英语报刊和原著，从中学习语言用法，没有仔细阅读过、理解过的东西千万不要在作文中使用，切忌中国式英语。
㈦ 2018年上海交通大学考博英语作文题目是什么
2018年上海交通大学博士入学英语考试已经于3月10日上午结束。根据参加考试的考生的回忆，内本年度上海交通容大学考博英语作文为一篇大作文。

作文涉及内容为：Do you agree or disagree with the following statement? Universities should spend more money in improving facilities (e.g. libraries and computer labs) than hiring famous teachers.
作文字数要求为：300字左右。
由于所有内容由考生提供，因此与正式的考题有所出入，但基本相差不大。现由华慧考博为各位考生整理公布，以供将来的博士生考生们复习参考！
㈧ 中国石油大学考博经验：考博英语作文该怎样
有的考生一味追抄求文章的完美而千篇一律地用结构复杂的句型，从而使得文章变的过于华丽反而显得冗长拖沓，就像是文言文般的“咬文嚼字”，让评卷教师感到“不太舒服”从而影响作文的得分，适得其反。长句短句各有千秋，简单句复合句也是各有特色：长句能够增加要点的内涵，使得句子“枝繁叶茂”，但使用不当会有失精准，运用起来不够灵活；不失时机地插入短句，会让文章长短有致，既达到了结构上的要求，有符合表达意义上的要求
