初級英語基礎語法 2
一、賓語從句的引導詞

英語語法名詞性從句知識點：八種賓語從句不省略that
引導賓語從句的that在下列情況下一般不省略：
1. 賓語從句前有插入語。如：
We hope, on the contrary, that he will stay at home with us. 恰恰相反，我們希望他和我們呆在家里。
2. 有間接賓語時。如：
He told me that he was leaving for Japan. 他告訴我他要去日本。
3. that在與之并列的另一個賓語從句之后。如：
He said (that) the book was very interesting and that(不省略) all the children like to read it.他說那本書很有趣，所有小孩都喜歡讀。
4. 在“it(形式賓語)+補語”之后時。如：
I think it necessary that he should stay here. 我們認為他有必要留在這里。
5. that從句單獨回答問題時。如：
—What did he hear? 他聽說了什么事?
—That Kate had passed the exam. (他聽說)凱特考試及格了。
6. 在except等介詞后。如：
He has no special fault except that he smokes too much.他除了抽煙太多之外,沒有什么特別的毛病。
7. 位于句首時。如：
That our team will win, I believe. 我相信我們隊會贏。
8. 在較為正式或不常用的.動詞(如reply, object)后。如：
He replied that he disagreed. 他回答說他不同意。
英語語法名詞性從句知識點：whether 和if引導名詞性從句
兩者均可用于及物動詞后引導賓語從句，表示“是否”，常可互換。但除此(用于動詞后引導賓語從句)之外，在其他情況下表示“是否”時，通常要用 whether 而不用 if，如用于引導主語從句、表語從句、同位語從句、讓步狀語從句、與or連用分別引導兩個分句等，或用于不定式前、用于介詞后、直接與 or not 連用等等。如：
Ask him whether [if] he can come. 問他能不能來。
The question is whether he can do it. 問題是他能不能做。
Answer my question whether you can help him. 回答我你是否能幫助他。
It depends on whether the letter arrives in time. 這取決于信是否來得及時。
注：在某些動詞后(如 discuss 等) 通常只用 whether。如：
We discussed whether we should hold a meeting. 我們討論了是否要開一個會。
英語語法名詞性從句知識點：that, why 與 because 引導表語從句
雖然三者均可引導表語從句，但 that 沒有詞義，而 why 和 because 有自己的意思;另外，雖然 why和 because 都可引導表語從句，但前者強調結果，后者強調原因。如：
The reason was that you don’t trust her. 原因是你不信任她。
The fact is that they are angry with each other. 事實是他們生彼此的氣。
He was ill. That’s why he was sent to the hospital. 他病了，所以被送到醫院來。
He was sent to the hospital. That’s because he was ill. 他被送到醫院，是因為他生病了。
英語語法名詞性從句知識點：that與whether引導名詞性從句
兩者均可引導賓語從句，也可引導語從句和表語從句(if 通常不行)，但兩者含義不同，whether (if) 表示“是否”，that 卻不表示任何含義。在它們所引出的從句中，that 表示一種肯定、明確的概念，而 whether (if) 則表示一種不肯定、不明確的概念。比較：
Whether he’ll come is not known yet. 他是否來還不清楚。
That he’ll come is known to us all. 我們都知道他會來。
類似地，動詞doubt (懷疑)后接賓語從句時，由于 doubt的含義不確定，故通常用 whether (if) 來引導其賓語從句，但若 doubt為否定式，則其后的賓語從句用 that 來引導。如：
I doubt if you are honest. 我懷疑你是否誠實。
I don’t doubt that you are honest. 我不懷疑你是誠實的。
英語語法名詞性從句知識點：the fact that引導主語從句
在許多情況下，當語義上需要用一個較復雜的that從句用主語時，若直接將其置于句首位置，則會顯得“頭輕腳重”。這時，我們通常采用的辦法便是使用形式主語it來改變句子結構。如：
That he had no girl friends worried his parents a lot.= It worried his parents a lot that he had no girl friends. 他沒有女朋友，這件事使他父母非常不安。
That he has fully recovered makes me feel good.=It makes me feel good that he has fully recovered. 他已痊愈，真令我高興。
That he had not said anything surprised everybody.=It surprised everybody that he had not said anything. 他一言不發，這使大家很吃驚。
用形式主語改變句子結構是許多同學都可能想得到的方式，屬通常思維，乃常規表達。但如果借助the fact這一輔助手段，按以下方式改寫句子，則會給人以耳目一新的感覺，許多閱卷老師會將其劃入“高級結構”的范疇。如：
The fact that he had no girl friends worried his parents a lot.
The fact that he has fully recovered makes me feel good.
The fact that he had not said anything surprised everybody.
