三丶重点短语
知识点：
过去进行时
a) 过去进行时由“was/were+动词ing形式”构成。以动词work为列，b) 其肯定式，c) 否定式，d) 疑问式以及简略答语见下表：
肯定式：I/He/She/It was working. We/You/ They were working.
否定式：I/He/She/It was not working. We/You/They were not working.
疑问式和简略答语：Was I working? Yes, you were.
Was he working? No, he wasn’t.
【注意】was not常简略为wasn’t; were not常简略为weren’t
e) 过去进行时的用法：过去进行时表示过去某一时刻或某一段时间正在进行的动作。这一特定的过去时间，f) 除有上，g) 下文暗示以外，h) 一般用时间状语来表示
not …until直到…才。表示动作在某时之前尚未开始，直到此时动作才开始。not…until可以用after或when来代替，但主句谓语动词要用肯定形式。Until为连词时后接时间状语从句，until作介词时，后面接表示时间的名词。Until 用于肯定句多表示动作或状态一直延续到until所表示的时间为止，意思为“直到…” from..till…中till往往表示不太具体的时间。From …to…或from…until常用来表示具体的时间。
find it…to do，it在此句中为形式宾语代表动词不定式，动词不定式为真正的宾语，常用于这种用法的动词有find, feel, think, make等。
“疑问词+不定式“结构相当于一个名词性从句，常常可用同等成分的从句代替。改写时，只需在疑问词后面加一个适当的主语(这个主语一般与主句的主语一致)，并将不定式改成适当形式的谓语即可。如，Where to go is still a question.= Where we should go is still a question.
when 与while:when连接的状语从句是个特殊句型，“前一个分句(谓语动词用过去进行时)+when(作并列连词，意思为“这时，突然”)+后一个分句(谓语动词用一般过去时)”表示在前一个动作正在进行的过程中突然发生了后一个动作， when强调动作的突然性，when后面的动词为非延续性动词;while表示“在….过程中”，强调在一段时间内，所以while引导的从句中的谓语动词必须为延续性动词。在状语从句中，若从句放在句首时，应用逗号与主句隔开。
感叹句的构成：What +a/an+形容词+单数名词+主语+谓语!What a good book it is!
What+形容词+复数可数名词+主语+谓语!What easy questions they are!
What+形容词+不可数名词+主语+谓语!What cold weather it is!
How+形容词+主语+be动词!How nice the watch is!
How +副词+主语+谓语!How hard they are working!
8.take place, happen“发生”：take place指“发生事先计划或预想到的事物”;happen指“一切客观事情或情况的偶然或未能预见地发生”。两者都是不及物动词或短语，后面不能跟宾语，也不能用于被动语态;happen的意义很广泛，而take place 仅用于历史上的事件，集会等，是先行布置而后发生或举行的事件，它不用于地震等自然界的现象。
happen to do 巧遇 sth happens to sb某人遭遇某事
9.不定代词all, both, each,every与not连用时，只表示部分否定，在否定句中用and连接两个宾语，表语，定语，状语时，只表示部分否定，并且否定 and后面的部分;如用or连接句中两个部分，则表示全部否定。如，She isn’t a bright and beautiful girl.她并不是一个既聪明又漂亮的女孩。(部分否定) She isn’t a bright or beautiful girl.她是一个既不聪明又不漂亮的女孩。(全部否定)。 www.68lou.com
