Stories about SpringPPT，第二部分內(nèi)容：課堂互動(dòng)探究
詞匯點(diǎn)睛
1 below prep. &adv. 低于；在……下面
[辨析] below與under
below
指位置低于某物或在某物下方，但不一定在正下方，所指范圍較寬，與above相對(duì)。
under
指在某物的正下方，有垂直在下的含義，與over相對(duì)。
2 as…as 和……一樣
[觀察] The temperature can be as low as 15℃.
氣溫可能會(huì)低至零下15攝氏度。
Li Ming runs as fast as Jim.李明和吉姆跑得一樣快。
[探究] as…as中間必須用形容詞或副詞的________(原級(jí)/比較級(jí))。其否定形式為not as/so…as，意為“比不上……；不如……”。例如：
Tony doesn't run as/so fast as Tom.托尼不如湯姆跑得快。
句型透視
We probably won't see any flowers until May or June!
我們可能直到五月或六月才能看到一些花兒！
[探究] (1)until用于否定句，構(gòu)成not…until，意為“___________”，通常與_______(瞬間性/延續(xù)性)動(dòng)詞連用，表示主句謂語動(dòng)詞所表示的動(dòng)作直到until所表示的時(shí)間才發(fā)生。
(2)not…until結(jié)構(gòu)可與before/after引導(dǎo)的從句相互轉(zhuǎn)換。例如：
I didn't go to bed until I finished all the homework.
＝I didn't go to bed before I finished all the homework.
＝I went to bed after I finished all the homework.
直到完成所有的家庭作業(yè)，我才上床睡覺了。
