名詞性從句

a. leaves        b. would leave        c. left        d. had left
[key]  b
[點撥] 本句子是過去時間，soon的出現就是表示過去將來。干擾項答案a以一般現在實施表示將來時，是適用于條件狀語從句，故不正確！
3.連接詞的選用關鍵要理解、弄清楚各自的含義和在句子中做的成分。
例12
i remember _____ this used to be a quiet village.
a. when        b. how        c. where        d. what
[key]  a
[點撥] 本題考查賓語從句的連詞。how和 where在從句中分別作地點和方式狀語，在此不合題意，而此句是一個完整句子即主系表結構，故排除what。本句欲表示的意思是：“我記得那個時候這里曾經是一個安靜的村莊”
例13
i would do _____ i can do to help them.
a. that        b. whatever        c. which        d. whichever
[key]  b
[點撥] i can do句中的及物動詞do沒有賓語，句子不完整，缺句子成分，whatever在句中可以作do的賓語。
4.that 在賓語從句中不可省略的情況。
1）當that引導的賓語從句中的狀語緊靠that時，或者說that從句中含有主從復合句時。
i’m sure that if you’ve lost it, you mast pay for it.
2）當賓語從句被it替代時
she has made it clear that she will have nothing to do with the decision.
3）當由兩個that引導的從句作同一個動詞或介詞的賓語時，第二個that不可省。
tom told the leader (that) jone had worker very hard and that he wanted him stay.
4）有插入語或其它成分把賓語從句和主句分開時。
he thinks, i’m afraid, that he is always right.
5）當that引導的賓語從句的主語是非謂語動詞或主語從句時。
they said that rubbing the girl’s leg might help.
6）從句的主語是that時。
she says that that is a real gold ring.
5.it 可充當形式賓語，代替真正的賓語從句，此時謂語動詞除帶賓語從句外，還帶賓補。
they want to make it clear to the public that they do an important job.
核心解讀四  表語從句
1. 當reason和 cause引導的從句做主語時，其表語從句多用that引導，而不用because引導。
the reason why he was late was that he missed the last bus.
2. because引導表語從句時，一般在句型“it(that, this) is because …”中說明原因；而在“it(that, this) is why…”中說明結果。
the teacher was very angry. that was because he was very late.
he was very late. that was why the teacher was angry.
3. as if/ as though也可引導表語從句。
it looks as if / as though it were going to rain.
4. 除that和wh-詞外，as 也可引導表語從句。
things are not always as they seem to be.
