Answer 1

11. B. At first 固定搭配，跟at the bigining 意思一样，用法一样
12. C. 句中有are说明主语不是单数，是复数，所以排除AB；路只有两边，没有三边，所以排除D
13. A. Twice a day,固定用法。只有一次两次必须用橡搭once twice,从第三信好次开始，可以用3 times a day
14. D. 地点定语从句用where。
15. C. 这句话不是强调强烈的因果关系，所以排除BD。A选项的for只有在句中才能表达因果，此题为句首，故排除。由于只是陈述结果，所以选C，因为有着这许多的问题需要被解决，所以原子车依然是不实用的。
