Unit 1　第2课时 ★学以致用★ 1.【辨析】problem与question problem和question都有“问题”的意思，但用法有所不同： (1)problem指说话者认为难以解决的问题，它与动词solve或settle(解决)搭配； (2)question指说话者需要寻找答案的问题，它常与动词ask或answer连用。 用question或problem填空 Please answer my __question(s)__ first and then I can help you solve the maths __problem(s)． 2．【辨析】too much，too many与much too (1)too much意为“太多”，与too many同义，但too much修饰不可数名词，too many修饰可数名词复数形式。 (2)much too意为“太”，起副词作用，在句中常用来修饰形容词或副词。 用too much，too many或much too填空 ①I have __too much__ homework to do. ②It's __much too__ expensive. ③Don't eat __too many__ sweets.They are bad for your teeth. 3．billion的用法 作数词，意为“十亿”，当表示具体的“几十亿”时，用“基数词＋billion”表示，此时billion不能加“s”。billions of…表示“数十亿……”，此时billion后要加“s”，并且不能与数词连用。 The government is spending __billions__(billion) of dollars protecting wild animals. 4．Hang on a minute！等等！ hang on意为“稍等”，常用于口语交际。 【拓展】Hang on.也用作电话用语，表示“别挂电话，等一下”。 ①__Hang__ __on__(等一等)—I'm not quite ready. ②等一下，我这就看看他在不在。 __Hang__ __on__—I'll just see if he's here.
