Stories about SpringPPT，第二部分内容：教材解读
1.The temperature can be as low as -15℃,but it can also reach 15℃.
as…as…意为“和……一样……”,用于同级之间的比较。其基本结构为:as+形容词或者副词的原级+as。
I gave him as much as he could eat.
他能吃多少,我就给了他多少。
【拓展】(1)as…as…的否定形式为“not as/so+形容词或者副词的原级+as…”,表示“不如……,比不上……”。
(2)as…as…结构中可以使用以下修饰词(组):just,exactly,not quite,half,
twice等,并且这些修饰词(组)必须置于第一个as之前,而不能置于其后。
2.We probably won’t see any flowers until May or June!
until意为“直到……为止”,引导时间状语从句。until用于肯定句时,主句的动作必须是延续性的,表示这一动作或状态一直延续到until所表示的时间为止;用于否定句时,主句的动作一般是非延续性动词,强调表示动作或者状态直到until所表示的时间才发生,构成not…until…结构,表示“直到……才……”。如果主句使用一般将来时态,则从句必须用一般现在时态表示将来。
The bus won’t start until everyone gets on.直到每个人都上车,公共汽车才会开动。
【拓展】till 是连词,意思是“直到……之时;在……之前”,通常用来表示时间,相当于until,只是语气较弱。
They waited here till ten o’clock.他们在这儿一直等到十点。
