完成句子，为什么用 so as to be received in time,考的是什么知识点，要详细解答

Question

All the food and clothes must be sent immediately ________________ ( 以便及时收到) by the people there. (so receive )

Answer 1

翻译：所有的食物衣服必须被立刻送出，以便于（它们可以）被那儿的人们及时收到。

1. so as to do sth是不定式短语做句子的目的状语，意思是“为了/以便于做某事”。
2. 该不定式to be received by...的逻辑主语即句子的主语all the food and clothes，它们之间明显为被动关系，即“所有的食物和衣服”是“被收到”的，所以必须使用不定式的被动结构to be done.
固定短语in time，意思是“及时”，做状语。
3. 所以正确答案为to be received in time，当然也可以用in order to be received in time或to be received in time.
