高二英語法之引導(dǎo)名詞性從句的連接詞
引導(dǎo)名詞性從句的連接詞可分為五類：
a.連詞：that（無任何詞意，不作成分，只起連接作用，賓語從句中�？墒÷裕�
1) my hope is that she will soon be well again. (表語從句)
我的希望是她能很快康復(fù)。
2) everybody hopes that she will soon be well again.（賓語從句）
大家都希望她能很快康復(fù)。
3) that she will soon be well again is our hope.（主語從句）
她能很快康復(fù)是我們的希望。
b. whether, if（均表示“是否”表明從句內(nèi)容的不確定性，不作成分）
1) whether he is coming or not doesn’t matter too much.(主語從句，不能用if)
2) i went in and asked if/whether they had a cheap suit.
3) i wonder whether/if he will come in such bad weather.
c. 連接代詞：what, whatever, which, whichever, (在從句中作主語，賓語，表語，指物)
1) ____he need is more time.
顯然，主語從句：he是主語，謂語動詞need缺賓語，因此應(yīng)填what.
2) tell us ___you saw and heard during your visit to that university.
3) this is not ___i want.
4) ____some people are against is ___other people are for.
5) the question is which team will win.
6) i have two apples, i don’t know which you want.
歸納：what一般用于不知道內(nèi)容或范圍的句子；which“哪一個……”一般用于給出內(nèi)容或范圍的句子�？勺髦髡Z，賓語，表語，還可作定語。
d. who, whoever, whom, whomever, whose（在從句中作主語，賓語，表語，定語，指人）
1) who will give us a lecture is unknown.
2) the question is who will come here.
e. 連接副詞：when, where, how, why, whenever, however, wherever (在從句中作狀語)
1) i have no idea how he learned about it.
2) where she has gone is not known yet.
3) when he will start is not known yet.
4) this is why he is late.
注意：連接代詞和連接副詞在句中既保留自己的疑問含義、又起連接作用，在從句中充當(dāng)從句的成分。
