花时间做某事的英文

主要有两个词可用，一个是take,一个是spend,还是举例子说明吧1 I spent two days on this project.2 I spent two days in solving this problem.3 It took me two days to solve this problem.4 How long did it take you to solve this problem?5 How many hours did you spend on this project?可以看出来，两个词的用法还是很灵活的，spend后面的on和in的介词选择根据后面是名词还是动名词来决定。
