sometimes意為“有時候”,比如,Sometimes, I will not eat breakfast, because it will be too late to go to school.（有時候,因為上學來不及了,我就不吃早飯.）同理,Lions donnot like water,but sometimes when the weather is hot,they will go into water to cool down. (獅子不喜歡水,但有時候天熱,它們也下水涼快去.)Sometimes,my uncle would bring me some sea food.（有時候我舅給我?guī)Шｕr來.）
some times意為“好幾次”,這里要注意times加了復數(shù)是“次數(shù)”“倍數(shù)”的意思了,不是時間的意思.比如,I have winned the first in my class for some times.（我得班上第一好幾次了.）同理,Shanghai is sometimes larger than Dalian. (上海比大連要大好幾倍.) I have lent my pen to you for some times!（我都借過你好幾次鋼筆了!）
sometime 意為“一段時間”,這里的time就是時間段的意思,some就是“一些”“一點”“一段”.比如,This work is really hard, I have done it for some time.（這活兒好難,我弄了一段時間.）其實也可以是“for an hour”"for a year"等等,就是這個意思.同理,The doctor is busy now, please wait for some time.（大夫忙著呢,請再等會兒.）Some time ago, there are no buildings here.(一段時間前,這兒還沒房子呢.)
sometime意為某個時候,這個比較特殊,要注意some除了“一些”以外的另一種意思：某個,指不確定的什么東西.比如somebody,someone就是“某人”的意思而不是“一些人”,你肯定明白something是“某東西”,道理一樣的.舉例如,I will visit you sometime in the next month.（下個月指不定什么時候我去看你.）同理,He cannot remenber the whole story, but it happened sometime ago. （他記不住整件故事了,但以前什么時候肯定有這事.） I know of her, sometime ago she worked in my company.（我跟她臉熟,她以前什么時候在我公司干過.）
總結：注意some的獨特意思——表示“不確定的某個”,
times是“次數(shù)、倍數(shù)”. （注：這個也可以表示“時代”,比如很有名的《時代》周刊就 是這個題目.）
