※ 引述《hoodoo (bug)》之銘言:
: 這是空英八月份雜誌的練習題:
: If you ______ to put a single drop of blood in an Olympic-size
: swimming pool, a great white shark could smell that.
: (A) are
S + be + to V. S (未來) 應該.../預定.../會做...
ex.The President is to visit Taiwan next week.
ex.You are to blame.
: (B) used
S + used + to V. S(過去)習慣...(現在已沒有)
ex.We used to grow peanuts.
另一個
S + be + used + to(介詞)+ Ving S(現在)習慣...(過去情況不知)
ex.I am used to walking to school.
及這一個
S + be + used + to V. S是被用來...
ex.This key is used to open this door.
: (C) fail
S + fail + to V. S 沒能.../忘記去...
ex.He did very well, but he still failed to break the record.
: (D) were
參考"假設語氣",用於未來幾乎不可能發生的假設
If + S + were + to V , S + would/could/should/might + VR
ex. If the sun were to rise in the west, I would marry you.
(A)只要你隨時放一滴血,鯊魚都聞得到,所以不用"計畫"(不是重點),所以不適合
(B)(C)的時間點跟意思也都不對
(D)是唯一可以在這裡解釋的
作者認定"put a single drop of blood in an Olympic-size swimming pool"
這件事未來幾乎不可能發生
所以在用假設法If時
採取以上句型
參考一下:)
: 答案是(D),但是我不太清楚為什麼是這個答案,也找不到是哪種文法,
: 所以想請教一下版上的英文老師們,麻煩各位先進。:)

師:「這本講義有不懂的地方可以私下來問我。」
生:「不能整本拿過去,一定要撕下來嗎?」
