狀語從句講解和練習(xí)(附答案)_百度文庫

1、一、狀語從句分類及常用連詞:類別 連 詞時(shí)間狀語從句 when, whenever, while, as, before, after, since, till, once, as soon as,etc.地點(diǎn)狀語從句 where,wherever原因狀語從句 because, since, as, for, now that, etc.目的狀語從句 in order that, so that, that, etc.結(jié)果狀語從句 so that, so that, such that, that, etc.條件狀語從句 if, unless, as(solong as, etc.讓步狀語從句

2、 though, although, even if, even though, however, whatever, as,etc.比較狀語從句 as as, so as, than, etc.方式狀語從句 as, as if, as though, etc.二、相似連詞的用法區(qū)別1.when, while, as,while 表時(shí)間,從句需用延續(xù)性動(dòng)詞,切不可用瞬間動(dòng)詞。when 表時(shí)間,從句既可以用延續(xù)性動(dòng)詞,又可以用瞬間動(dòng)詞。as 表時(shí)間,與 when 相似,但側(cè)重強(qiáng)調(diào)主從句動(dòng)作同點(diǎn)或同段進(jìn)行。when, while后可以接分詞短語。2.because, as, since, for語

3、氣 位置 意義because 最強(qiáng) 前或后 “原因” ; 表客觀因 果關(guān)系;回答“”as 較強(qiáng) 前 “由于” ; 把眾人所 知的事實(shí)當(dāng)作理由since 較弱 前 “既然”;就對(duì)方陳 述的事實(shí)作為理由for 最弱 后 “理由”;對(duì)某一事 實(shí)進(jìn)行推斷的理由注:上面所說的“前”,指從句在主句之前;“后”,指從句在主句之后。3.so that, so that, such thatso that “以便”、“結(jié)果”表目的和結(jié)果。注意:在從句中有情態(tài)動(dòng)詞表 目的。無情態(tài)動(dòng)詞表結(jié)果。so that “如此的以致于”表結(jié)果。該結(jié)構(gòu)常見于:1.so+形/副+that 2.so+形+a(an+單數(shù)名詞+that

4、 3.so +many/much+復(fù)數(shù)名詞(不可數(shù)名詞 +thatsuch that “如此的以致于”表結(jié)果。該結(jié)構(gòu)常見于:1.such +a(an+形+名詞+that 2.such +形+復(fù)數(shù)名詞/不可 數(shù)名詞+that4.though, although, as,though, although在句首表“盡管”兩者都可以用。但句后不能再用 but 。 下列情況只能用 though : as though (=as if; even if (=even though 在句末表示“然而”as 表示“盡管”,從句的表語、狀語等成分要倒裝。5.whatever, however,wherever,

5、 whenever它們是 what, how, where, when的強(qiáng)勢(shì)語氣。分別等于:no matter what, no matter howno matter where, no matter when原因狀語從句: because, since, as和 for 都表示原因。常常令我們不知該用 哪個(gè)好。我們來比較一下。because 語勢(shì)最強(qiáng),回答 why 提出的問題,用來說明人所不知的原因。當(dāng)能 夠很明顯的看出原因或人們已知原因, 就用 as 或 since 。 如:I don t like that coat,because the color looks terrible.由

6、 because 引導(dǎo)的從句如果放在句末, 且前面有逗號(hào), 則可以用 for 來代替。 但如果不是說明直接原因, 而是多種情況加以推斷, 就只能用 for 。 如:He is not here, because / for his mother is ill.1.
