(2) “When _____ he come?” “I don’t know, but when he _____, I’ll tell you.”

A. does, comes         B. will, will come

C. does, will come      D. will, comes

答案選 D，第一個 when 疑問副詞，用于引出一個特殊疑問句；第二個 when是從屬連詞，用于引導(dǎo)時間狀語從句。

(3) “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

答案選 D，第一個 when 引導(dǎo)的是主語從句，第二個 when引導(dǎo)的是時間狀語從句。

8. The bridge, which _____ 1688, needs repairing.

A. is dated from                                        B. was dated from

C. dates from                                            D. dated from

【陷阱】此題容易誤選B或D，認為句中用了 1688 這個過去時間，所以應(yīng)選過去時態(tài)，又因為 date from 不用于被動語態(tài)，所以只能選D。

【分析】其實此題的最佳答案應(yīng)是C，因為 date from 的意思是“自某時起存在至今”(＝have existed since)，它通常用于一般現(xiàn)在時，而不用過去時態(tài)(盡管其后接的總是表示過去的時間)。如：(www.hz123456.com)

The church dates from 1176. 這座教堂是六世紀建的。

The castle dates from the 14th century. 這座城堡是14世紀建的。

但若所談?wù)摰臇|西現(xiàn)在已不復(fù)存在，則可用一般過去時。如：

The church, which dated from the 13th century, was destroyed in an earthquake two years ago.  那座教堂是13世紀建成的，兩年前在一次地震中被毀了。

注：與 date from 同義的 date back to 也有類似用法。

9. “You’ve left the light on.” “Oh, so I have. _____ and turn it off.”

A. I’ll go                                                  B. I’ve gone

C. I go                                                     D. I’m going

【陷阱】容易誤選D。

【分析】A和D兩者均可表示將來，填入空格處似乎都可以。但實際上只有A是最佳的，因為根據(jù)上下文的語境來看，“我去把燈關(guān)掉”這一行為是說話人聽了對方的話后臨時想到的，而不是事先準(zhǔn)備的。而按英語習(xí)慣：will 和 be going to后接動詞原形均可表示意圖，但意圖有強弱之分，如果是事先考慮過的意圖，要用 be going to；如果不是事先考慮過的，而是說話時刻才臨時想到的意圖，則用 will。比較：

“I’ve come out without any money.” “Never mind, I will lend you some.” “我出來沒帶錢。”“沒關(guān)系，我借給你。”(句中用will lend，表示“借”錢給對方是臨時想到的，即聽了對方的話后臨時作出的反應(yīng))

I’ve bought a typewriter and I’m going to learn to type. 我買了臺打字機，我想學(xué)打字。(句中用 be going to learn to type，表示說話人要學(xué)打字是事先準(zhǔn)備的，并為此買了臺打字機)
