1、表語從句2連接詞1時態(tài)2語序3目錄3表語是用來說明主語的身份、性質(zhì)、品性、特征和狀態(tài)的，表語常由名詞、形容詞、副詞、介詞短語、不定式、動詞的-ing、從句來充當(dāng)，它常位于系動詞（be, become, appear, seem, look, sound, feel, get, smell等詞）之后。表語從句（Predicative Clause）就是用一個句子作為表語。說明主語是什么或者怎么樣，由名詞、形容詞或相當(dāng)于名詞或形容詞的詞或短語充當(dāng)，和連系動詞一起構(gòu)成謂語。4知識點(diǎn)一：表語從句一定要用陳述語序False: The question is when can he arrive at t

2、he hotel.Right: The question is when he can arrive at the hotel.知識點(diǎn)二：引導(dǎo)名詞性從句時if/whether（是否）用法辨析if不能引導(dǎo)表語從句，只能用whether 來引導(dǎo)。引導(dǎo)賓語從句時if/whether可以互換，但介詞后面的賓語從句只能用whether來引導(dǎo)。位于句首的主語從句只能用whether來引導(dǎo)，同位語從句也只能用whether來引導(dǎo)。False: The question is if the enemy is marching towards us.Right: The question is whether

3、the enemy is marching towards us.5知識點(diǎn)三：表語從句時態(tài)不像賓語從句，在有表語從句的復(fù)合句中，主句時態(tài)和從句時態(tài)可以不一致。Right: The question is who will travel with me to Beijing tomorrow.Right: The question is why he cried yesterday.知識點(diǎn)四：that在表語從句中不可以省掉表語從句只能置于主句之后，而主句的動詞只能是連系動詞。名詞性從句在be等系動詞后作表語時被稱為表語從句。6知識點(diǎn)五：常見句型分析“That is why.”是常用句型， 意為“

4、這就是的原因/因此”， 其中why引導(dǎo)的名詞性從句在句中作表語， 該句型通常用于針對前面已經(jīng)說明過的原因進(jìn)行總結(jié) That is why you see this old woman before you know, Jeanne.珍妮，這就是現(xiàn)在這個老太婆出現(xiàn)在你面前的原因。（前文提到Jeanne對老婦人顯得蒼老憔悴深感詫異，說話人對她講述了其中的原因之后，用這一句來進(jìn)行概括）。7【題目】Im afraid he is more of a talker than a doer, which is _ he never finishes anything.【選項(xiàng)】AthatBwhenCwhyD
