Being interested in the relationship of language and thought, Whorf developed the idea that the structure of language determines the structure of habitual thought in a society.后面的这个句子，它的主谓宾都是齐全的，主语Whorf ,谓语developed, the idea是宾语。句子的基本成分有了，那么剩余的就是句子的定语、状语和补语等这样一些成分了。being interested in就是现在分词做原因状语的，因为对语言和思维之间的关系感兴趣，所以沃夫才形成了这种想法。
I get up early to catch the early bus.在这个句子中，主语I，谓语get up,to catch the early bus做的就是目的状语这样一个成分，我早早的起床，目的就是为了赶上早班车。
状语，一般都是放在主语之后，动词之前的，且时间放在前面，地点放在后面。而对信息量较小的状语，我们可以采用将状语放到主语后面这种方式。如：Being interested in the relationship of language and thought, Whorf developed the idea that the structure of language determines the structure of habitual thought in a society.译文：由于对语言和思维之间的关系感兴趣，所以沃夫才形成了这种想法：语言的结构决定了一个社会中习惯思维的结构。

When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London, they were not taken seriously.
当有报道进入伦敦公园，that是report的定语从句，也就是解释report的内容，是说有一只野生美洲狮在距离伦敦以南45英里的地方被发现了。had been spotted是个被动语态后边they，指代复数名词，前半句只有reports，这些报道并没有得到严肃对待。
However, as the evidence began to accumulate, experts from the Zoo felt obliged to investigate, for the deions given by people who claimed to have seen the puma were extraordinarily similar.
for表原因，因为。for后边的句子主语是deions,谓语是were similar.given by people过去分词作定语修饰deion，由谁给出的这一描述who引导定语从句修饰people，声称看见过美洲豹的人。这一描述(跟报道)惊人的一致。
Nowhere do 1980 census statistics dramatize more the American search for spacious living than in the Far West.
该句是倒装句，把nowhere提前引起部分倒装，原型是：1980 census statistics dramatize more the American search for spacious living nowhere than in the Far West.nowhere …than译为“除了……没有其他地方”译为：1980年的美国人口统计更能显示出，美国人迁往遥远的西部(而不是其他地方)是为了寻找广阔的生活空间。在部分倒装里，do做助动词置于主语前more是比较级的用法。
Critics also argue that commercial genetic testing is only as good as the reference collection to which a sample is compared.
第一句话，critics是主语argue是谓语，that后面是宾语从句，然后to which引导的是修饰collections的定语从句，因为compare的固定用法是compare to/with sth,在which引导从句时候compare后面的to提到了which前面。评论家也指出商业的基因检测仅仅和类似作为样本的参考搜集一样。
But because hard laughter is difficult to __4__, a good laugh is unlikely to have __5___ benefits the way, say, walking or jogging does.
Because引导原因状语从句，后边是主句，不好理解的可能是way后边的成分，the way做方式状语，does代替have measurable benefits.这句话是说因为强笑很难保持，所以不可能以衡量散步或慢跑好处的方式来衡量大笑带来的好处。
