I have to look after her at home. 妈妈病了，我得在家照 看她。 You must finish your homework first. 你必须先完成作业。 so that 以便 【解析】so that后面需要加一个完整的句子，引导的是目的状语从句，表示主句 中谓语动词的目的，但目的是否达到并没有说明。从句中经常使用can， could，may等情态动词。 【例句】We’ll have to tie ourselves to our beds so that we won’t float away in our sleep! 为了我们不在睡梦中飘走，我们将不得不把我们自己绑在床上！ I run fast so that I may catch the train. 我快跑为的是要赶上火车。 Please read aloud so that I can hear you. 请大声朗读，好让我能听到。 Let me write down your telephone number so that I can call you later. 让我 记下你的号码，以后好打电话给你。 We study hard so that we may work better. 我们努力学习，以便我们能更 好地工作。 Close the gate so that the dog can’t get out. 关上门，不要让狗跑出去。 Come close so that I can see you clearly. 到跟前来，我好看清你。 Stand up so that I can see how tall you are. 你站起来好让我能看看你有 多高。 重点句型 as ... as 像……一样 【解析】此句型的全写是：A+动词+as+形容词/副词原级+as+B（+动词）。A和B 一样…… 【例句】This room is as big as that one (is). 这个房间和那个一样大。 He is as clever as his brother (is). 他和他的哥哥一样聪明。 Mary dances as well as Kate (does). 玛丽和凯特跳舞一样好。 I can run as fast as you (can). 我可以和你跑得一样快。 如果形容词是many或much，后面可以加名词。如： I’m going to take as many photos as I can. 我准备拍尽可能多的照片。 He has as much bread as I (do). 他有和我一样多的面包。 【拓展】此句型的否定式为：not as / so ... as意为“不如……”。否定式中的第一 个as也可用so，第二个不可以改，必须用as。肯定式中的两个as也都 不能改。如： This ruler isn’t as long as yours. 这把尺子没有你的尺子长。 Bob doesn’t write so carefully as Ben. 鲍勃写字没有本认真。 It takes sb. some time to do sth. 某人花费多长时间去做某事。 【解析】这句中的It是形式主语，没有词义，真正主语是后面的不定式to do。 句中的sb.如果是代词，则要用其宾格形式。 【例句】It’ll take us about four days to get there. 我们将要花费大约四天的时间到 那儿。 It takes me half an hour to keep my diary every day. 我每天花半个小时的 时间记日记。 【拓展】此句型可以和spend替换。上述例句可换成： We will spend four days (in) getting there.
