It often takes me half an hour to watch TV every evening.每天晚上我常常用半小时看电视。2. It took me ten yuan to buy the book last week.上周我花了 10 元买那本书。3. How long will it take them to finish the work?完成那项工作需要花费他们多少时间？●使用该句式要注意的是：sb. 假如代词表示用宾格；take 随时态改变；句中的时间用段时间,对此提问用 how long。例：It takes us more than two hours to do our homework every day.It took us more than two hours to do our homework yesterday.It will take us more than two hours to do our homework tomorrow.How long did it take you to do your homework yesterday?二. It’s time to do sth. 该做某事了同义句为：It’s time for sth. / doing sth. 例：It’s time to go to school. 该上学了。(It’s time for school.)It’s time to get up. 该起床了。(It’s time for getting up.)此句可以扩展为：It’s time for sb. to do sth. 是某人做某事的时间了。for sb. to do sth. 是动词不定式的复合结构。例：It’s time for me to work.到我工作的时间了。It’s time for you to go to school.到你们上学的时间了。三. 主语+be(not)+adj. +enough to do sth. (某人、某物)足够(不能)做某事。例：The boy is old enough to go to school.这个孩子到了上学年龄。I’m tall enough to reach the top of the tree.我够高能够到树顶。●此句是肯定句时,可以用主+be +so+ adj.+ that 的句型(即 so…that…表示的结果状语从句)来替换。The boy is so old that he can go to school.I’m so tall that I can reach the top of the tree.●此句是否定句时,既可以用 so…that…引导的结果状语从句来替换,还可以用 too…to…句式替换...
