安得广厦千万间,大庇天下寒士俱欢颜 英语翻译
下面是Burton Watson的版本，个人感觉这个版本更好：
Where can I get a big broad shelter a thousand, ten thousand spans wide,huge roof that all the world’s poor people can share with smiling faces?
寒士，这里是儒雅的说法，其实不仅仅指读书人，以杜甫的个性，因该是说所有穷困之人。
(C5H5N)2ZnBr2汉语是怎么说的~
The reaction of 2-methoxycyclohexanone (I) with dialkyl carbonate by means of NaH/KH in THF gives 3-methoxy-2-oxocyclohexanecarboxylic acid allyl ester (II), which is condensed with (3R,4R)-4-acetoxy-3-[1(R)-tert-butyldimethylsilyloxy)ethyl]azetidin-2-one (III) by means of NaH in THF yielding the condensation product (IV) as a mixture of the alpha- and beta-stereoisomers at the methoxy group. The protection of the NH group of (IV) with tert-butyldimethylsilyl (TBS) trifluoromethanesulfonate affords the bis-TBS-protected compound (V), which is stereospecifically decarboxylated with palladium acetate, formic acid and triphenylphosphine to the protected azetidinone (VI) also as alpha- and beta-isomers. The selective desilylation of (VI) with tetrabutylammonium fluoride (TBAF) in acetic acid gives the O-protected azetidinone (VII) also as a mixture, which is epimerized by sequential treatments with lithium diisopropylamide (LDA), with ZnBr2 and finally with diethyl malonate to afford the alpha-(S)-epimer (VIII). The acylation of (VIII) with benzyloxalyl chloride and pyridine in dichloromethane gives the N-benzyloxazyl derivative (IX), which is cyclized by means of triethyl phosphite in refluxing xylene yielding (4S,8S,9R,10S)-10-[1(R)-(tert-butyldimethylsilyloxy)ethyl]-4-methoxy-11-oxo-1-azatricyclo[7.2.0.0(3,8)]undec-2-ene-2-carboxylic acid benzyl ester (X). The desilylation of (X) with TBAF in THF/acetic acid affords (XI) with a 1-hydroxyethyl group, which is hydrogenated with H2 over Pd/C in dioxane in the presence of 3,3,6,9,9-pentamethyl-2,10-diazabicyclo[4.4.0]dec-1-ene (XII) giving the addition salt (XIII). The treatment of (XIII) with potassium 2-ethylhexanoate yields the corresponding potassium salt (XIV) (1), which is finally esterified with 1-chloroethyl cyclohexyl carbonate (XV) by means of benzyltrimethylammonium chloride in DMF.
英语八年级下册第七单元SectionB 2b翻译
2014年春季八年级下册（人教版）英语 Unit7 2b
8：30在成都熊猫研究基地，林伟和其他熊猫饲养员正在准备给小熊猫喂奶。在9：00，他们发现大多数熊猫已经醒来、也饿了。小熊猫看见饲养员，它们就高兴的过来，有的向它们的朋友走过来、有的翻身滚过来。
“它们多么可爱和聪明。我把它们像自己的孩子那样好好照看。我每天给它们洗澡、喂食和陪它们玩。它们对我有特别的感情。”林伟喜欢她的工作，但是这份工作也非常困难。
熊猫生育孩子很少，大概每两年才生育一只。小熊猫常常死于疾病、生存时间很短。一只成年熊猫每天用12小时以上时间吃大约10千克竹子。许多年前，在中国竹林和熊猫都比现在多。但是人们就开始砍伐森林，熊猫吃竹就变少了。科学家说现在野生熊猫不到2000只。另外的200只熊猫生活在中国或者其它国家的动物园、熊猫研究基地。
成都的一个教育项目是教生活在城市的孩子们了解熊猫以及其它濒临灭绝动物常识。他们派专职人员去学校给孩子们讲解拯救濒临灭绝动物的重要性。（教）孩子唱歌或者制作熊猫及其它野生动物的宣传画。教孩子帮助拯救熊猫的一种方法。中国政府也计划为熊猫种更多竹林让熊猫生活。我们都希望将来的熊猫比现在多一些。
