落下的

Sometimes the neighbour's pigeons land on my windowledge Cooing softly Where the great poplar at the window has somehow grown beyond the fourth-floor roof They skim round its crown and back The sunlight on their fluffy feathers Alive day by day I keep coming indoors empty-handed And throwing book and jacket on the bed As the days hurry by I can bring scarcely anything home Even after days away Only you remain and the little room Living day by day We have grown used By an unspoken pact to the room's breadth A pair of pigeons cooing softly on the windowledge Which at many instants belong to us Day by day Dust that falls on book spines gradually yellows Perhaps it is otherwise That life, if it does, provides I know that the unwitting request is not excessive And that summer turns to autumn Perhaps fallen leaves will swirl after a night of rain It does not mean a return to green shade deep in sunlight A house-cleaning when leisure affords Feelings may come on latent even as Irrelevancies are spoken softly The instant when a first trembling on the lips teaches you happiness Lasts till the end of life A request always voiced unwittingly

有时候，邻家的鸽子落在我的窗台上咕咕地轻啼窗口的大杨树不知不觉间已高过了四层楼的屋顶它们轻绕那些树冠又飞回来阳光在蓬松的羽毛上那么温柔生命日复一日我往往空着手从街上回来把书和上衣掷在床上日子过得匆匆忙忙我时常不能带回来什么即使离家数日只留下你和这小小的屋子生活日复一日面对无声无息的默契我们已习惯了彼此间的宽容一对鸽子在窗台上咕咕地轻啼他们在许多瞬间属于我们日复一日灰尘落在书脊上渐渐变黄如果生活时时在给予那也许是另一回事我知道，那无意间提出的请求并不过份我知道，夏日正转向秋天也许一场夜雨过后就会落叶纷飞不是说再回到阳光下幽深的绿荫日子需要闲遐的时候把家收拾干净，即使轻声述说些无关紧要的事情感也会在其间潜潜走过当唇际间最初的战栗使你感知了幸福这一瞬已延伸到了生命的尽头而那些请求都是无意间说出的

Yet such was the Fright I had taken at the Moors, and the dreadful Apprehensions I had of falling into their Hands, that I would not stop, or go on Shoar, or come to an Anchor; the Wind continuing fair,'till I had sail'd in that manner five Days: And then the Wind shifting to the southward, I concluded also that if any of our Vessels were in Chase of me, they also would now give over; so I ventur'd to make to the Coast, and came to an Anchor in the Mouth of a little River, I knew not what, or where; neither what Latitude, what Country, what Nations, or what River: I neither saw, or desir'd to see any People, the principal thing I wanted was fresh Water: We came into this Creek in the Evening, resolving to swim on shoar as soon as it was dark, and discover the Country; but as soon as it was quite dark, we heard such dreadful Noises of the Barking, Roaring, and Howling of Wild Creatures, of we knew not what Kinds, that the poor Boy was ready to die with Fear, and beg'd of me not to go on shoar till Day; well Xury said I, then I won't, but it may be we may see Men by Day, who will be as bad to us as those Lyons; then me give them the shoot Gun says Xury laughing, make them run wey; such English Xury spoke by conversing among us Slaves; however I was glad to see the Boy so cheerful, and I gave him a Dram (out of our Patroon's Case of Bottles) to chear him up: After all, Xury's Advice was good, and I took it, we dropt our little Anchor and lay still all Night; I say still, for we slept none!

但是，我已被摩尔人吓破了胆，生怕再落到他们的手里；同时风势又顺，于是也不靠岸，也不下锚，一口气竟走了五天。这时风势渐渐转为南风，我估计即使他们派船来追我。这时也该罢休了。于是我就大胆驶向海岸，在一条小河的河口下了锚。我不知道这儿是什么地方，在什么纬度，什么国家，什么民族，什么河流。四周看不到一个人，我也不希望看到任何人。我现在所需要的只是淡水。我们在傍晚驶进了小河口，决定一等天黑就游到岸上去，摸一下岸上的情况。但一到天黑，我们就听到各种野兽狂吠咆哮，怒吼呼啸，不知道那是些什么野兽，真是可怕极了！这可把那可怜的孩子吓得魂飞魄散，哀求我等天亮后再上岸。我说，"好吧，佐立，我不去就是了。不过，说不定白天会碰见人。他们对我们也许像狮子一样凶呢！"佐立笑着说，"那我们就开枪把他们打跑！"佐立在我们奴隶中能用英语交谈，虽然发音不太地道。见到佐立这样高兴，我心里也很快乐。于是我从主人的酒箱里拿出酒瓶，倒了一点酒给他喝，让他壮壮胆子。不管怎么说，佐立的提议是有道理的，我接受了他的意见。于是，我们就下了锚，静静地在船上躺了一整夜。我是说，只是"静静地躺着"，我们事实上整夜都没合过眼。

METHODS: The model of tissue damaged submandibular gland in 10 rats was made by deligation. One week later, the gland tissue was obtained to harvest submandibular gland stem/progenitor cells by enzyme digestion in vitro. Following 10-14 days of primary culture, small round cells were collected, purified and subcultured for monoclonal culture.

Root-derived organic carbon is composed of three compartments: root detritus, root eaudates and root symbionts, which represents a large important and potential C sink in forest ecosystems, The known responses of root derived organic carbon and heterotrophic microbes to elevated CO2 were reviewed. Overall, increases in root biomass, productivity, and exudation indicate an augmentation of C inputs into the soil via roots, although changes in root lifespan are still unclear and may modify this flux positively or negatively, Altogether, changes in root chemistry and morphology that may augment soil C storage under elevated CO2 include decreased N concentration and wider root diameter, Alternately, a shift in rooting depth upwards in the soil profile may increase average turnover rates of root detritus. Effects of CO2 concentration on C qualities of root exudates and root symbionts are the least understood components discussed here, Changes of soil heterotropic microbial activity and community under elevated CO2 still remained large uncertainties.

林木根源有机C包括根东通过根枯落物、根系分泌物和根共生菌周转3条途径向土壤输入的有机C，它是森林生态系统中一个重要的、潜在的C汇，综述了根源有机C与其微生物对CO2浓度升高的响应，虽然对根系寿命的变化尚不清楚，但CO2浓度升高将导致根系生物量、生产量、死亡量和分泌物的增加；同时，CO2升高亦促使根共生菌生物量的增加而增加了共生菌的C归还潜力，表明CO2升高使根源有机C的输入增加了，CO2农度升高情况下，根系化学性质和形态特征的这些变化均有利于增加土壤C的吸存；而根分布深度的降低则对土壤C吸存不利；CO2浓度升高对根分泌物和根共生菌质量的影响研究则极少，CO2浓度升高下土壤微生物活性和群落组成的变化存在较大的不确定性，目前CO2浓度升高下林木根源有机C对森林长期C吸存的贡献仍很不清楚。

As the flakes that fall thick upon a winter's day, when Jove is minded to snow and to display these his arrows to mankind- he lulls the wind to rest, and snows hour after hour till he has buried the tops of the high mountains, the headlands that jut into the sea, the grassy plains, and the tilled fields of men; the snow lies deep upon the forelands, and havens of the grey sea, but the waves as they come rolling in stay it that it can come no further, though all else is wrapped as with a mantle so heavy are the heavens with snow- even thus thickly did the stones fall on one side and on the other, some thrown at the Trojans, and some by the Trojans at the Achaeans; and the whole wall was in an uproar.

像冬日里的一场大雪，下得纷纷扬扬，密密匝匝――其时，统治世界的宙斯卷来飞落的雪花，对凡人显耀攻战的声势。他罢息风力，一个劲地猛下雪片，覆盖了山岳中迭起的峰峦和突兀的岩壁，覆盖了多草的低地和农人精耕的良田，飘落在灰蓝的海波里，遍洒在港湾和滩沿上，只有汹涌的长浪可以冲破它的封围，其余的一切全被蒙罩在白帐下，顶着宙斯卷来的大雪的压挤。就像这样，双方扔出的石块既多且密，有的飞向特洛伊人，还有的出自特洛伊人之手，扔向阿开亚人，整道护墙发出震耳欲聋的巨响。
