Unit 2 第2课时
★学以致用★
1.There was nothing strange about that.那没什么好奇怪的。
nothing是不定代词,strange是形容词,形容词修饰不定代词时,要放在不定代词之后。

2.Alice got up and ran across the field after it.爱丽丝站起来并跟着它(兔子)跑过田野。
(1)across作介词,意为“越过”,常用表达“go/run/swim/…+across”相当于cross。
(2)run after sb./sth.意为“追逐、追赶某物或某人”。
The police are __running__after__(追捕)the man named John Smith.
3.【辨析】while与when
两者都表示“当……时”,引导时间状语从句,但用法有所不同:
(1)when引导的时间状语既可以指时间点,也可以指一段时间;while引导的时间状语只可以指一段时间。
(2)when引导的时间状语从句中的谓语动词可以是终止性动词,也可以是延续性动词;while引导的时间状语从句中的谓语动词必须是延续性动词或表示状态的词。
__When__ the teacher came in,we were talking.=__When/While__ we were talking,the teacher came in.(填入一个适当的引导词)
4.【辨析】think of与think about
(1)两者表示“考虑;对……有某种看法”时,可互换使用。
(2)think of表示“想到;想起”等意义时,不能与think about互换。
