英語和漢語的表達(dá)方式有很大的區(qū)分點(diǎn)，所以很多考生在接觸到GRE閱讀文章的時(shí)候都需要一個(gè)轉(zhuǎn)換的過程。每天閱讀一篇優(yōu)質(zhì)的GRE雙語閱讀可以大大縮短轉(zhuǎn)換的時(shí)間，提高閱讀速度。下面是小編為大家整理的一篇關(guān)于GRE雙語閱讀：合成生物學(xué)應(yīng)對流感病毒。

Flu vaccines and synthetic biology —— Going viral

流感病毒與合成生物學(xué)：向病毒行進(jìn)

IF A new and deadly strain of influenza were to arise, putting together a vaccine against it in the least possible time would be a priority.

如果出現(xiàn)了一枝新型致命性流感毒株，那么當(dāng)務(wù)之急就是要在盡可能短的時(shí)間里拼湊出對應(yīng)的疫苗。

To test how quickly that could be done a group of researchers have just had a race with themselves.

一支研究小組為了測試到底疫苗 " 出欄 " 速度有多快，小組內(nèi)部展開了一次速度競賽。

They have not quite matched the show sometimes given by workers at the Venetian arsenal, who would assemble a galley in a single day in order to overawe visiting foreign dignitaries.

當(dāng)然和威尼斯工人是比不了的，他們?yōu)榱苏饝赜慰蜁r(shí)不時(shí)表演一番在一天之內(nèi)安裝一艘大帆船。

But Philip Dormitzer, Craig Venter and their colleagues did create the crucial component of a flu jab in four days and four hours.

但是，菲利普 · 多米提奇、克雷格 · 文特爾和同事們的的確確在四天零四小時(shí)研發(fā)了流感病毒疫苗了一支重要組成部分。

Dr Dormitzer, who works for Novartis, a drug company, and Dr Venter, eponymous founder of the J. Craig Venter Institute in San Diego, reported their record-breaking attempt in this week's Science Translational Medicine.

多米提奇博士在諾華制藥公司工作，文特爾博士是位于圣地亞哥 J · 克雷格 · 文特爾的同名創(chuàng)始人。本周《科學(xué)轉(zhuǎn)化醫(yī)學(xué)》雜志刊載了二人創(chuàng)紀(jì)錄的研發(fā)結(jié)果。

It began with the transmission to them from America's Biomedical Advanced Research and Development Authority of the sequence data for the haemagglutinin and neuraminidase genes of a unknown flu virus.

一開始，他們得到 " 美國生物醫(yī)學(xué)高級研究所和發(fā)展管理局 " 的序列數(shù)據(jù)，關(guān)于不知名的流感病毒的血凝素和神經(jīng)氨酸酶基因的數(shù)據(jù)。

The team took this information and used it to make DNA that contained both the gene sequences themselves and the genetic apparatus needed to let a cell read those sequences and produce proteins from them.

小組利用數(shù)據(jù)制作包含兩種成分的 DNA，分別是基因本身序列和需要細(xì)胞識別這些序列并且從中產(chǎn)生蛋白質(zhì)的基因組織。

They then put these pieces of synthetic DNA — which were, in effect, tiny chromosomes — into cell cultures derived from dog kidneys, which have been found particularly effective for this kind of work.

之后，研究人員將合成的 DNA 碎片植入從犬類腎臟中提取的細(xì)胞培養(yǎng)物中。經(jīng)研究發(fā)現(xiàn)，犬類腎臟的細(xì)胞培養(yǎng)物質(zhì)非常適合此類實(shí)驗(yàn)。

The dog-kidney cells duly churned out viruses, suitable for seeding the process of vaccine manufacture, that contained the proteins in question.

犬類腎臟不負(fù)眾望地大量產(chǎn)出病毒，當(dāng)然也就適合批量生產(chǎn)含尚未定性蛋白質(zhì)的疫苗。

Since these two proteins are the variable elements that stop new strains of flu being recognised by the immune systems of people who have had influenza in the past, this is an important step forward.

過去人們感染流感，他們的免疫系統(tǒng)會受到新流感毒株的影響，而如今這兩種易變的蛋白質(zhì)可以阻止影響繼續(xù)下去，也算是向前邁出了重要的一步。

Experiments on ferrets showed that these seed viruses stimulated the animals' immune systems in the desired way, producing protective immunity.

在白鼬身上做的實(shí)驗(yàn)，按照預(yù)期顯示出這些種子病毒刺激到了白鼬的免疫系統(tǒng)，白鼬體內(nèi)產(chǎn)生出保護(hù)性抗體。

Having a seed is not the same thing as being able to make a vaccine in large quantities.

種苗實(shí)驗(yàn)并不難代表大量臨床實(shí)驗(yàn)。

But it is an important first step.

但這是重要的開始。

Novartis, in collaboration with the commercial arm of Dr Venter's enterprise, Synthetic Genomics, hopes to create a bank of seed viruses using this method.

文特爾博士合成基因公司商業(yè)部門和諾華制藥有合作項(xiàng)目，諾華制藥希望能夠利用這種方法研制出大量的源病毒。

That will speed matters up even more.

為的是可以加快疫苗研發(fā)進(jìn)度。

But the fact that something not actually in the bank could be knocked up at short notice if necessary is comforting.

事實(shí)其實(shí)是這樣的：如果必要性能夠讓人覺得心寬，那么只要一聲令下不確定的東西也可以準(zhǔn)備完畢。
