until 與till 的區(qū)別：

　�。�1）在句首時(shí)多用until 。例如：

　　Until then I had known nothing about it.

　�。�2）在from … till … 這一詞組里，用till比用until普通，但也可用until。例如：

　　I worked from morning till late at night.

　　There was a beautiful Mozart concert on the radio from six  o′clock until a quarter past seven.

　　（3）在“good—bye till …”及“up till…”中，till不能用until 替代。例如：

　　Yes, we can help one another. Good–bye till then.

　　I’ve lived in the country all my life up till now.
