Question

麻烦帮我解决几个英语问题！

1。在完成时中，

by+时间（过去） 表示什么意思？
2.在虚拟语气里 情态动词+动词原形的用法 的用法好混乱啊！

这里有2个句子；
1，He walked lightly（ ）以免惊醒婴儿
2，Were I in your place（ ）我会毫不犹豫的抓住机会。

还有这句话该怎么写；
But for his help（ ）我们就不会以这么低的价格租到房子了。

我希望能有更多的机会吧我们在课堂上学到的东西应用与实践。
We hope to have more opportunities apply knowledge learned in the class to the practice.
这个句子可以这么翻译吗？

Answer 1

1，过去完成时
表示到过去某个时间点时，已经做过某事
例如：到去年9月，我已经学习英语两年了。
By last September,I had learned English for 2 years.
2, 原来应该做某事而没有做

in case of waking up the baby

I would have grasped the opportunity without the least hesitation.

we would have not rent the house with so low price.

We hope that there are more opportunities to put the knowledge learned in the class into practice
