由词而句，这两天讨论长难句的分类与分析。考研英语中的长难句分类如下：

一、复合句

When a new movement in art attains a certain fashion, it is advisable to find out what its advocates are aiming at, for, however farfetched and unreasonable their principles may seem today, it is possible that in years to come they may be regarded as normal.

[参考译文]

当艺术上的一项新运动达到一定流行程度时，最好先弄清该运动倡导者的目的，因为，无论他们的创作原则在今天看来多么牵强、多么荒谬，在未来这些理论有可能会被视为正常的东西。

二、并列句

• While talking to you, your could-be employer is deciding whether your education, your experience, and other qualifications will pay him to employ you and your “wares” and abilities must be displayed in an orderly and reasonably connected manner.

[参考译文]

与你谈话时，可能成为你未来老板的人会考虑你所受的教育、你的经历和你的其他资历是否在雇佣你以后会给他带来好处。你的“资历”和能力必须有条不紊、合理连贯地展示出来。

[结构分析]

这也是一个并列句，包含两个分句。第一个分句的主干是your could-be employer is deciding whether...，其中whether引导一个宾语从句whether your education, your experience, and other qualifications will pay him to employ you；第二个分句的主干是your “wares” and abilities must be displayed...。 注意：pay sb. to do sth.此处的意思是“做…对…有利”；“wares”的本义是“商品、货物”，但在本文中，作者认为找工作就是推销自己，所以结合本文的背景，wares的意思是“（求职者的）资历或能力”。

三、定语从句

The change met the technical requirements of the new age by engaging a large professional element and prevented the decline in efficiency that so commonly spoiled the fortunes of family firms in the second and third generation after the energetic founders.

[参考译文]

通过雇用大量的职业人才，这一变化满足了新时代的技术要求，防止了效率下降——在过去，这种效率下降经常使家族公司在充满活力的创业者之后的第二代或第三代毁掉全部财产。
