while除了有“当/在……时候”的意思外（注意：引导的句子谓语动词只能是延续性动词！），另外的两层意思也是考查的重点：（1）while = although “尽管”、“虽然”，引导让步状语从句；（2）while的意思是“然而；可是”，常用来表达对比关系。

[注意]where引导地点从句时，可以引导定语从句或是逻辑地点状语从句。当它在定语从句中作地点状语，指代地点时，这时可以用in which, on which, at which, to which, from which等结构代替。但是它引导逻辑地点状语从句时，没有这样用法。[例句] You should put the book where it was.把书放回原处。

what在英语中非常活跃,它可以用来引导主语从句、宾语从句、表语从句，但是不用来引导定语从句。在句子里可以充当主语、宾语、表语、定语，既可以指人，也可以指物。[例句] What is the population of the world? 世界的人口有多少？ What did you pay for this picture? 这幅画你付了多少钱？

在as引导的非限制性定语从句中，连接代词as在句子中可以作主语、宾语或表语等，可以指人或物。其在定语从句中的位置比较灵活，即可以在句子前面，在句子中间或句子末尾。常用的结构有：as we all know;as is well known to…;as is often the case;as is said/mentioned above;as has been said before;as I told you before;as is evident;as often happens;as can be seen;as is/was expected;as we expect;as I can remember等。[注意1]as通常只指整个句子的内容，不表示部分内容。
[注意2]as引导的非限制性定语从句通常指“事先可以预料到的”“料想到的”，表达“好”的方面。[注意3]as引导限制性定语从句时，常构成the same…as…;such…as…;so/as …as…等结构。在从句中既可以指人、物，也可以指整个句子。[例句] This is also part of your work, as I told you before.我曾告诉过你，这也是你工作的一部分。The man was a teacher, as was evident from his way of speaking.从那人说话的样子可明显看出，他是个老师。

which引导的非限制性定语从句既可以指整个句子内容，也可以指句子的部分内容（如单词或词组等），在句子中可以作主语、宾语（动词或介词的）、定语等。注意它在句子中的位置：只能放在主句后，不能放在主句前。表达的内容是“不好的”、“事先没有预料到的”等时，常用which，只指物。

说明︰此句型意为“值得„”。worth 是<介系词>，使用时要用<名词>或<动名词>做<受词>，形成<介系词词组>，当 <形容词>用。worth 之后接<动名词>时，<主词>必须为该<动名词>之<受词>，否则<动名词>之后须另加<介系词>，使<主词>做其<受词>。这种<句型>不可用虚<主词> it 做<主词>。
London is a city worth visiting.伦敦是值得参观的城市。
