1．Ifyouopenupanymedicinecupboardorgotoanymedicinecounterintheworld，itislikelythatyouwillfindaspirinandpenicillin.

[句式分析]　该句为主从复合句。

主句中it为形式主语，that引导的主语从句为真正的主语；

if引导条件状语从句。

[自主翻译]　倘若你打开世界上任何一个药柜或去任何一个药品柜台，你很可能会发现阿司匹林和青霉素。

2．Itwasin1897thataEuropeanchemistcalledDrFelixHoffmannproducedaspirinfromthischemical.

[句式分析]　此句是强调句型“Itis/was＋被强调部分＋that/who＋句子的其余部分”，句中强调时间状语in1897。

calledDrFelixHoffmann为过去分词短语作后置定语。

[自主翻译]　正是在1897年，一位名叫费利克斯·

霍夫曼的欧洲药剂师提取了这种化学物质，制成了阿司匹林。

3．Notonlyhasaspirinprovedvitalforreducingfeverandhelpingstoppain，buttherearealsootherthingsthataspirincanhelpwith.

[句式分析]　本句中notonly...butalso...连接两个并列分句。

notonly置于句首，所在分句使用部分倒装结构。

thataspirincanhelpwith是定语从句，修饰先行词otherthings。

[自主翻译]　阿司匹林不仅被证明对于退烧、止痛必不可少，而且还有其他用途。

4．Itastonishedhimtoseethebacteriasurroundingthemoulddead，whichmeantthatthemouldhadkilledthem.

主句中it为形式主语，真正的主语为动词不定式结构toseethebacteriasurroundingthemoulddead，其中surroundingthemould为现在分词短语作后置定语修饰thebacteria，dead为宾语themould的补足语；

which引导的非限制性定语从句中又含有that引导的宾语从句。

[自主翻译]　他惊讶地发现，这种霉周围的细菌都死了，这意味着是这种霉杀死了它们。

故选D。
