It said Hans-Hilger Ropers, director at Max-Planck-InstituteforMolecular Genetics in Berlin, has tested a pillthwartinghyperactivity in certain brain nerve cells, helpingstabiliseshort-term memory and improve attentiveness.

柏林马普学会高分子研究所所长罗普斯表示，他已经对能减少某些脑神经细胞过度活跃的药物进行了试验，这种药物能帮助生物稳定短期记忆力和改善注意力。

His proposals include introducing molluscs into the city's waterways as natural bio-filters, adding bicycle lanes and hastening the cleaning and rezoning of 7,600 acres (3,100 hectares) of contaminated land.

他的建议包括在城市的水道中引入软体动物作为自然生物过滤器，在道路上增加自行车道，并加速清理并重新规划7600英亩（3100公顷）被污染的土地。

After selecting a highly potent strain of poxvirus that was able to traffic to tumors when administered intravenously to mice the authors engineered the virus such that it would target only specific cancer cells -- those with increased expression of a protein known as E2F and/or activation of signaling downstream of a protein known as EGFR.

以毒攻毒：设计病毒，攻击肿瘤一种新的治疗癌症的方法正在开发中：用病毒感染肿瘤杀死癌细胞留下正常细胞不被伤害。这些病毒以病毒疗法而著称。在一项新的研究当中，David Kirn 和他在旧金山Jennerex生物疗法同事已经描述出利用新病毒疗法后老鼠和兔子抗肿瘤效应的发展。在选择高度特异性痘状病毒后才能有效的到达肿瘤生长地方，然后通过静脉途径给老鼠。

He stooped and lifted a single leaf from the ground, handing it to the two-headed creature.

他弯下身子从地上拿起了一片叶子，递给了那个双头生物。

Who would like to moe into embryonic stem cell work but who won't because of the political uncertainties," says Stephen Minger, director of the Stem cell Biology Laboratory at King's College in London, speaking to me in his cramped and cluttered office."

&我知道在美国很多人都愿意转移到胚胎干细胞的领域，但是碍于不明朗的政治因素，&伦敦King's College 干细胞生物实验室的主管Stephen Minger在他混乱不堪的办公室里对我说，&我认为美国真的有落后的危险。&

Upon returning to flesh, Chantico had hoped to find semi-intelligent fire creatures.

对于身体，他希望能看到这个火生物会是半智能的。

But Lovelock saw that if you had a vast network of coevolutionary impulses, such that no creatures could escape creating its own substrate and the substrate its own creatures, then the web of coevolution spread around until it closed a circuit of self-making and self-control.

他认为，假使有一张具有共同进化冲力的大网，它网罗所有生物使无可逃遁地为它织造扩展所需的基质，而且这基质不断地增殖的话，这个共同进化的网络就会向周围扩展直到封闭成为一个自给自足、自我控制的轮回。

但洛夫洛克别有见地，他认为，假使有一张具有共同进化冲力的大网，它网罗所有生物使无可逃遁地成为它织造扩展所需的基质，而且这基质不断地增殖的话，这个共同进化的网络就会向周围扩展直到封闭成为一个自给自足、自我控制的轮回。

He was accepted by the School of Medicine, Yale University.

他在学校里的成绩不错，尤其是在生物和化学上更加突出，这对我们来说是极大的安慰。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
