Stories about SpringPPT，第二部分內(nèi)容：Language points
1. The temperature can be as low as -15℃.
as...as意為“和……一樣”，表示同級的比較。結(jié)構(gòu)為：as+ adj./ adv. +as
(1) This film is as interesting as that one.
這部電影和那部電影一樣有趣。
(2) Your pen writes as smoothly as mine.
你的鋼筆書寫起來和我的一樣流暢。
其否定式為not as/so +adj./ adv. +as。例如：
This dictionary is not as/so useful as you think.
這本字典不如你想象的那樣有用。
若有修飾成分，如twice, three times, half, a quarter等，則須置于第一個as之前。例如：
Your bag is twice as expensive as mine.
你的袋子比我的貴一倍。
2. We probably won’t see any flowers until May or June!
until“直到”，表示某一種行為一直持續(xù)到某一時間

我咋晚學(xué)英語一直學(xué)到9點鐘。 (表示9點前一直在學(xué))
not...until“直到……才”表示直到某一時間，某一行為才發(fā)生，之前該行為并沒有發(fā)生。
I did not study English until 9 o’clock last night.

3. We had to wear our jackets and boots…
have to 意為“必須，不得不”，后接動詞原形。 have to 的否定式是don’t have to

① must強調(diào)人主觀認(rèn)為必須做某事,而have to強調(diào)客觀情況迫使人不得不做某事; ②must只用于一般現(xiàn)在時中,沒有人稱和數(shù)的變化,而have to可用于多種時態(tài)中,并且有人稱和數(shù)的變化。
