13. 這是賓語從句還是狀語從句

I don’t know if it ______ or not tomorrow.

A. rain                     B. rains                    C. will rain               D. is raining

此題應(yīng)選C。容易誤選B。稍有點(diǎn)英語基礎(chǔ)的人都知道英語中有這樣一個習(xí)慣：當(dāng)主句為一般將來時或含有將來含義時, 其時間狀語從句、條件狀語從句、讓步狀語從句等, 通常要用一般現(xiàn)在時表示將來意義。所以考生一見到此句, 就不加思索地認(rèn)為應(yīng)選B。

其實(shí), 句中的if引導(dǎo)的不是條件狀語從句(if≠如果), 而是賓語從句(if＝是否), 句意為：我不知道明天是否會下雨。

做以下各題, 注意分清是狀語從句還是名詞性從句：

1. I don’t know if he _____, but if he ____ I will

let you know.

A. comes, comes       B. will come, will come

C. comes, will come  D. will come, comes

2. The weather report says that it ____ tomorrow, but if it _____, we will stay home.

A. rains, rains            B. will rain, will rain

C. rains, will rain       D. will rain, rains

3. —When _____ he come?

—I dont’know, but when he _____, I’ll tell you.

A. does, comes          B. will, will come

C. does, will come     D. will, comes

4. —When he _____ is not known yet.

—But when he ____, he will be warmly welcomed.

A. comes, comes       B. will come, will come

C. comes, will come  D. will come, comes

答案：1. D 2. D 3. D 4. D

14. 這個引導(dǎo)賓語從句的that可省略嗎

He says ______ he is attacked he will certainly counterattack.

A. if                         B. that                     C. if that                  D. that if

此題應(yīng)選 D。容易誤選 A。其實(shí)此題也可將詞序改為：

He says that he will certainly counterattack ifhe’s attacked. 他說他若受到攻擊, 他一定會反擊。

按照語法規(guī)則：當(dāng)主句與賓語從句之間插有其它成分時引導(dǎo)賓語從句的that通常不能省略。如：

她答應(yīng)要是誰找到他的兒子, 她會給他一大筆錢。

正：She promised (that) she would give him a lot of money if anyone found her son.

正：She promised that if anyone found her son she would give him a lot of money

誤：She promised if anyone found her son she would give him a lot of money

他說等他妻子回來, 他就離開。

正：He said (that) he would leave when his wife came back.

正：He said that when his wife came back he would leave.

誤：He said when his wife came back he would leave.

她在信上說她愛我。

正：She said (that) she loved me in the letter.

正：She said in the letter that she loved me.

誤：She said in the letter she loved me.
