名词所有格(Possessive Case) 在英语中,有些名词在词尾加-’s表示所有关系,这种格式称为该名词的所有格。例如:My father's car,Today's newspaper。 名词所有格的构成: 单数名词在词尾加-’s。例如:Denn’s turn,the daughter’s shirt,my aunt’s house 复数名词词尾是-s或者是-es,仍要加-’。例如:The students’ books,The boxes’ tops. 复数名词词尾不是-s或者-es,仍要加-’s。例如:men’s clothes,children’s toys 名词词组的所有格在最后一个词的词尾加-’s。例如:an hour and a half’s walk ,,Jenny and Mary's bedroom 's在清辅音后读/s/,在浊辅音和元音后读/z/。在/t/后读/ts/,在/d/后读/dz/。 名词所有格的另一种形式是在介词of后加名词,这种形式多用于表示没有生命的东西的名词。例如:the name of the book,the root of the tree,the legs of the desk
when或because引导的状语从句 (Adverbial Clause with “when” or “because”) 用来修饰主句或主句中的动词、副词、形容词的从句叫状语从句。状语从句可分为时间状语从句、原因状语从句、地点状语从句等。学习状语从句时,要注意连词的正确使用,主句与从句的时态呼应的。本次学习when引导的时间状语从句和Because引导的原因状语从句.。 1.when引导的时间状语从句 1)表示“当……的时候”=at the time that……。此时,when从句用来说明主句动词发生的背景。例如: I couldn't help laughting when I saw it. When i was a little boy,My grandmother told me the the story of Chang'e. 2)表示“无论什么时候……”,与whennever的意思差不多,但语气比较轻。例如: Remember me when you wear the cap. 注意: 在when引导的时间状语从句当中,通常用一般现在时态表示将来。例如: I will think of you when i wear it. I'll go on with the work when I come back tomorrow. Please tell him about it when you see hin back 2.Because引导的原因状语从句 Because引导的原因状语从句一般置于主句之后,表示直接的原因,语气最强。例如: I feel comfortable here Because it is safe. He was fixing a pair of pants for an old because they were too long. I like winter because i like to ski and skate. 注意: 1)Because习惯上不与so连用。在汉语中我们习惯说“因为……所以……”,但在烟雨中却不能将so与because连用。例如: 因为下雨,所以我们待在家里。 正:Because it was raining,We stayed at home. It was raining, so we stayed at home. 误:Because it was raining, so we stayed at home. 2)Because与because of短语转换 Because引导的原因状语从句有时可以与because of短语转换。例如: He can't come because he is ill./He cat because of his illness
