All the following sentences definitely indicate future time EXCEPT_____(2013)

A、 Mother is to have tea with Aunt Betty at four.
B、 The President is coming to the UN next week.
C、 The school pupils will be home by now.
D、 He is going to email me the necessary information.

【正确答案】 C

【答案解析】解析：2013年第58题。A、B、D项都是将来时的各种表达，唯独C项的will，看似是将来时标志，其实不然，因为和by now矛盾，这里will的用法是指you thinksomething is true，表示说话人自己的看法，比如：That will be Tim coming homenow．Ask anyone and they will tell you the same thing．故本题选C。
