很多时间用英语怎么说

很多时间可以用英语表达为"a lot of time"或者"a great deal of time"。
这两个短语都比较常用，它们来源于拉丁语，"a lot of time"的"lot"来源于拉丁语的"latus"，意思是"宽的"，"a great deal of time"的"deal"来源于拉丁语的"dilatare"，意思是"扩大"。
下面是一些例句：
I spent a lot of time studying for the exam. 我花了很多时间来复习考试。
We need a great deal of time to finish this project. 我们需要很多时间来完成这个项目。
