很多时间的英语

I have a little time to do homework.

I do not have free time to do homework.

就是much time。 many time有语法的错误，而a lot of time用法不够地道

大多数时间 Most time英 [taim] 美 [taɪm] n. 时间; 时机; 时代; 所需时间; vt. 为…安排时间; 测定…的时间; 调准（机械的）速度; 拨准（钟、表）的快慢; vi. 合拍; 和谐; 打拍子; adj. 定时的; 定期的; [美国英语]分期（付款）的; int. [体育]时间到，（一场或一局等的）比赛时限，暂停;

much/a lot of time都可以many不行，因为time是不可数名词

I don"t have a lot of time for homework

I don't have a lot of time to do my homework.

I donot have too much time on my homework!
