從句

1.賓語(yǔ)從句

在復(fù)合句中,由一個(gè)句子充當(dāng)賓語(yǔ),這個(gè)句子叫做賓語(yǔ)從句。賓語(yǔ)從句主要有三種類型,分別是that引導(dǎo)的賓語(yǔ)從句、if或whether引導(dǎo)的賓從、連接代詞和連接副詞引導(dǎo)的賓語(yǔ)從句。 常見的賓語(yǔ)從句引導(dǎo)詞:that、if、whether、what、who、where、why和how。

Eg. I am sad that you refused me. 我很難過你拒絕了我。

2.定語(yǔ)從句

定語(yǔ)從句在中考和高考中出現(xiàn)的頻率都非常高。在復(fù)合句中,修飾名詞或代詞的從句叫定語(yǔ)從句。被修飾的名詞或代詞叫先行詞。定語(yǔ)從句一般放在先行詞的后面。常見的關(guān)系代詞包括that,which,who(賓格whom,所有格whose),as 等,關(guān)系副詞包括where,when,why等。

Eg. Lily likes music that is quiet and gentle. 瑪麗喜歡輕柔的音樂。

3.狀語(yǔ)從句

狀語(yǔ)從句就是由一個(gè)句子在復(fù)合句中充當(dāng)狀語(yǔ)。所以狀語(yǔ)從句又可以分為時(shí)間狀語(yǔ)從句、地點(diǎn)狀語(yǔ)從句、原因狀語(yǔ)從句、目的狀語(yǔ)從句、結(jié)果狀語(yǔ)從句等等。每種狀語(yǔ)從句都有特定的引導(dǎo)詞:

(2)時(shí)間狀語(yǔ)從句:when, while, as, before, until, till, since

considering that, in that

(4)目的狀語(yǔ)從句:so, so that, in order that, that, to the end that, in case,for fear that,lest

(5)結(jié)果狀語(yǔ)從句:so...that, such that, so that, with the result that

(6)條件狀語(yǔ)從句:if,unless,if only,only if,in case,suppose/supposing

(that),provided/providing(that),on condition that,so/as long as
