是some times还是several tiomes?

是some times还是several tiomes? some times和several times有什么区别啊? several times 可以说some times 为什么新概念上说没有这个用法 应该用several times 而不能用some times? [急]请问several times和for several times的区别请问for several times没了for还能表示“几次”的意思吗.如果想说“我见过他几次”,是用“I have seen him for several times”还是去掉for也可以?如果可以希望能 several times用什么替换比较好several times用a number of times 替换好还是用 three times 替换好 英语翻译“需要一些时间”是need some time 还是take some times several times 译中 some some 和times是两个单词 some times 是有时,那some other 到底有没有some times 表达几次的说法?有些书籍或是网站说有some times这种说法表示几次,而有些书籍或网站又说没有some times的说法,要表示几次的时候,会说several times,请问哪个是对的? several times 是现在完成时的时间状语吗 time是可数名词还是不可数?为什么有时候看到的是some time,有时候又是some times? some times Repeat it ____,or you will forget it.A.some time B.sometime C.some times D.several time 具体是several millions of students还是several million students 是 other several months还是over several months “几天”的英语是several days,还是for several days?
