- 试题详情及答案解析
- finish the difficult task on time, we had to work day and night for weeks.
| A．So as to | B．So that |
| C．In order that | D．In order to |
- 答案：D
- 试题分析：考查不定式用法；so as to do sth是不能放在句首的；BC两项后面通常要接句子而不是动词原形。D项in order to do sth为了做某事，通常放在句首做目的状语。句意：为了准时完成这个困难的任务，我不得不夜以继日工作了好几个星期。故D正确。
考点：考查不定式用法
