1、表語從句講解及專項練習(xí)表語從句講解及專項練習(xí)概念： 表語從句是在復(fù)合句中作表語的名詞性從句。放在系動詞之后,一般結(jié)構(gòu)是“主語+系動詞+表語從句”可以接表語從句的連系動詞有be, look, remain, seem 等。 The trouble is that we are short of money. 困難是我們資金短缺。 That is why stone walls are used instead of fences around New England fields. 這就是為什么在新英格蘭用石頭墻 而不用柵欄的原因。 At that time, it seemed as if I

3、表語從句。that在引導(dǎo)表語從句日無詞義，而whether有詞義，意為、“是否”。這時主句的主語常常是些抽象名詞，如question（問題）,trouble（麻煩）,problem（問題）,result（結(jié)果）,chance（可能性）,suggestion（建議）,idea（想法）, reason（理由）等。表語從句對主句主語進行說明、解釋，使主語的內(nèi)容具體化。例如： The trouble is （that） she has lost his money. 麻煩的事是他丟了錢。 The question is whether we need more ice cream. 問題是我們是否還需

9、is question.C. 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.D. that 在表語從句中不可以省掉?；居梅ū碚Z從句只能置于主句之后，而主句的動詞只能是聯(lián)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例如： The problem is how we can get the things we need.問題是我們怎樣能弄到
