關閉窗口 一道介詞怪考題
有這樣一道題，是關于介詞的，有點怪：
Who is it up _________ decide whether to go or not？
A. to to B. for for C. to for D. for to
許多同學一看選項排除了A和B，因為像兩個介詞連在一起用一般是不可能的。至于C和D，該選哪個呢？顯然空格的 decide 是動詞，所以它前面應是不定式符號to，而不能是介詞 for，所以此題應選D。此分析盡管有些道理，但所選答案還是錯了，正確的選項應是A。同學們應該熟悉 up to 的用法，它的意思很多，其中一個用法是表示“該由……負責”“在于……”“取決于……”。如：
“Shall we go out?” “It’s up to you.” “我們出去嗎？”“這由你決定。”
When we start is up to you. 我們什么時候出發由你來定。
It’s up to you to decide whether to go or not. 去還是不去由你來決定。
若對上面一句中的you 提問即有：
Who is it up to to decide whether to go or not？
請再看以下幾題；
(1) I asked him what he hoped _________ his birthday.
A. on on B. at at C. to to D. for for
答案選D。比較：He hoped for a bike for his birthday. 若對其中的 a bike 提問即得到 What did he hope for for his birthday.
(2) Would you tell me what subject you were good _________ school?
A. at at B. in in C. for for D. with with
答案選A，be good at = 擅長于，at school = 在校，在學校讀書。
(3) The books we _________ nothing to do with this subject.
A. have have B. do do C. read read D. need need
答案選A，we have 是修飾 the books 的定語從句，have nothing to do with 是短語，意為“與……無關”。
(4) Whoever has a strong _________ not leave his work half way done.
A. shall shall B. will will C. can can D. may may
答案選B, 第一個will 是名詞，意為“意志”，have a strong will 意為“意志堅強”；第二個 will 是助動詞，意為“將”。
