sometime 過(guò)去（或?qū)?lái)）的某一時(shí)間
sometimes 有時(shí)
some times 幾次
some time 一段時(shí)間
1.maybe 副詞,意為“可能”、“也許”,通常用于句首,有時(shí)也放在句中或句末；may be 是情態(tài)動(dòng)詞“may”加動(dòng)詞“be”,意為“可能是”、“可能在”等.比較以下各組句子,含義相同,但結(jié)構(gòu)不同：
你也許是對(duì)的.
正：Maybe you are right.
正：You may be right.
他可能迷路了.
正：Maybe he has lost the way.
正：He may have lost the way.
正：It may be that he has lost the way.
2.副詞 maybe 可單獨(dú)用作答語(yǔ),但 may be 不能這樣用.如：
A：Do you think he’ll come back?你認(rèn)為他會(huì)回來(lái)嗎?
B：Maybe.(Maybe not.) 也許會(huì)回來(lái)吧(也許不會(huì)回來(lái)吧).
some day原意“若干天”,引申義"來(lái)日"(將來(lái)的某一天),或"總有一天".常用于將來(lái)時(shí),如:
Some day my prince will come 總有一天我的王子會(huì)出現(xiàn)
Some day I’ll find my love 總有一天我會(huì)找到真愛.
*someday 意為"有一天",多指將來(lái)的一天.在這一點(diǎn)上,someday=some day.就是說(shuō)上面的例子完全可以換成someday.
基本上兩者可以通用,除了some day可以拆開用,如:
There is still some day before he comes.離他來(lái)還有些日子.
