　　(b)：表示时间的副词now, then 等副词开头的句子，谓语动词为 come, go, be, follow 等时，需用完全倒装。

　　(a)：never, hardly, scarcely, seldom, little, not until, no, in no case, by no means, on no account 等表示否定意义的副词或介词短语放于句首。

　　(h)：用于表示祝愿的祈使句中 May you be in good health!

　　(i)：省略 if 的虚拟条件 Were I you, I would not do it in this way.

　　6：名词性从句

　　在句子中起名词作用的句子叫名词性从句，它包括主语从句、宾语从句、表语从句和同位语从句。

　　名词性从句连接词的用法

从句成分	人	物
从句主干缺失（主语，宾语，表语）	who, whoever（主语）	what, whatever
	whom, whomever（宾语）
从句缺失定语	whose，which, what
从句缺失状语	when, where, why, how
从句成分完整	缺“是否”意义：whether, if
	不缺意义：that

　　7：定词性从句

　　定语从句(Attributive Clauses)在从句中作定语，修饰一个名词、名词词组或代词，被修饰的名词、词组或代词即为先行词。定语从句通常出现在先行词之后，由关系词(关系代词或关系副词)引出。

　　定语从句关系词的用法(看从句成分)

先行词	主语	宾语	定语	状语
人	who/that	who/whom/that	whose	/
物	which/that	which/that		when（=介词+which）
				where（=介词+which）
				why（=for which）

　　8：状语从句

　　状语从句在复合句中作状语。根据句子的含义，它可表示时间、地点、原因、目的、结果、条件、行为方式、比较、让步等。

　　状语从句一般由连词(从属连词)引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。

　　状语从句的构成：

　　引导词+状语从句+“,”+主句：When she came in, I stopped eating.

　　主句+引导词+状语从句：We were about to leave when he came in.

　　状语从句的关键是掌握不同状语从句的常用连接词和一些特殊的连接词。

　　状语从句引导词的用法
