英语介词的各种用法

英语介词的各种用法英语介词的各种用法 请看下面一道题： Who is it up _____ decide whether to go or not? A. to to B. for for C. to for D. for to 许多同学一看选项排除了 A 和 B，因为像两个介词连在一起用一般是不可能的，有趣的重复，易错的考题。至于 C 和 D，该选哪个呢?有的同学是这样分析的：decide 是动词，所以它前面应是不定式符号 to，而不能是介词 for，所以此题应选 D。此分析尽管有些道理，但所选答案还是错了，正确的选项应是 A。同学们应该熟悉 up to 的用法，它的意思很多，其中一个用法是表示“该由……负责”、“在于……”、“取决于……”。如： “Shall we go out?” “It’s up to you.” “我们出去吗?”“这由你决定。” When we start is up to you. 我们什么时候出发由你来定。 It’s up to you to decide whether to go or not. 去还是不去由你来决定。 若对上面最后一句中的 you 提问便可得到下面一句： Who is it up to to decide whether to go or not? 请再看以下几道题，先不看解析，自己独立思考一下，看看能否选对： 1.
