1.时间表达法
(1)教材原句 It's seven thirty!七点三十分了!
英语中的时间通常用以下两种方法表达:
(2)用法:①直接表达法。整点时间可以用“钟点数(基数词)+o'clock”来表达,有时也可以省略 o'clock。非整点时间可以按照“钟点数+分钟数”来直接表达时间。
②间接表达法。如果分钟数少于30分钟,可以用“分钟数+past(过)+钟点数”表示,意为“几点过几分”。如果分钟数超过 30分钟,可以用“(60分钟-原分钟数)+to(差)+(原钟点数+1)”表示,意为“差几分到几点”。如果分钟数是 30分钟,可以用“'half+past十钟点数”表示。

3.let's的用法
(1)教材原句 Let's have breakfast,让我们吃早餐吧。
(2)句式结构 Let's十动词原形(十其他),
(3)用法:因此句型用来提出建议。let's是let us的缩写形式,后接动词原形。赞同别人的提议,常用“OK./All right. /Great!/Good idea(好主意),”等回答;如果不赞同,可先说 Sorry,再说明原因。其他表示提建议的句型“Shall we ...?”“Why not ...?”“How/What about ... ?”
例句:Let's go and watch a film.让我们去看电影吧。
-Let's play football in the park.让我们在公园踢足球吧。
-Good idea.好主意。
-Shall we have dinner at home?我们在家吃晚饭怎么样?
-Great!太好了!
