为使着火,放火烧。如:

了。

2.still(adv.)意为“安安静流地”、“一动不动地”,作方式状语。如:

He lay still in bed and was deep in thought.他静静地躺在床上,陷入了沉思。
3.with + n. ./ pron. + p. p. 表示状态、境况等。这种复合结构中的名词或代词是后面过去分词的
动作对象。如:

上的形象。
with + n./pron. + -ing/prep.phr./adv./to -v.都可以在句中作状语,表示方式、状态、情
况、原因等。如:

4.nor意为“也不”、“也没有”,引起分句时,要用倒装语序。如:

I don’t know,nor do I care.我不知道,也不在乎。
Neither of them knew where I would go,nor(did they know)when I would start.他们谁也
不知道我要去哪里,也不知道我什么时候动身。
5.expense(n.)意为花费,费用(总称)时,是不可数名词;意为一笔花费时,是可数名词。如:
The expense of a good education is great.良好教育的花费昂贵。

词组 at someone’s expense意为花费某人的钱。如:

6.inspire(vt,)意为鼓囊,鼓励,还常接复合其语。如:

I was inspired to work harder.我被鼓励更努力工作。
7.词组no more than意为只不过,强调少的含义,而词组not more than意为不多于,只是客观说
明数目,不强调多少。如:
The boy is no more than 15 years old.男孩只有十五岁。
The boy is not more than 15 years old.男孩不超过十五岁。
8.表示动作特别是持续动作的动词如work,study,live等可以用一般时态,也可以用进行时态,
而表示短暂动作的瞬间动词如begin,close,jump等通常用一般时态,而不用进行时态。如:
Suddenly it began to rain.突然下起雨来。(用一般过去时,不宜用 Suddenly it was beginning
to rain.)
Hearing the good news,we jumped for joy. 听到好消息,我们高兴得跳了起来。(用一般过去式,
不宜用Hearing the good news,we were jumping for joy.)
但有些表示短暂动作的瞬间动词可以用进行时态表示“逐渐”、“重复”、“即将”等含义。如:
We were beginning to get tired.我们开始感到疲乏。(此句意思是:We were gradually getting
tired.)
He is jumping up and down.他在跳上跳下。(用进行时态表示动作重复)
The train is arriving.火车就要到了。(用进行时态表示即将发生的行为)
9.某些表示状态和感觉的动词如be,see,love,hear,like,hate,need,guess,mean等一般不
能用于进行时态,因为它们不能表示正在进行的动作。但如果词义转变为正在进行的动作,则可用进行时
态。如:
Do yon see anyone over there?你看到附近有人吗?(表示感觉,用一般时态)
We are seeing Mr Li off.我们在为李先生送行。(表示正在进行动作,用进行时态)
I hear someone singing an English song.我听到有人在唱英语歌曲。(表示感觉,用一般时态)
We are hearing an English talk.我们正在听英语报告。(表示正在进行动作,用进行时态)
10.get sth.going意为使某物开始活跃,开始工作(casue sth.to be
active,working,etc.)。如:
Getting the factory going in these hard times is almost impossible.在这个困难时期,想把
这家工厂搞活是不可能的。
It’s difficult to get the car going on cold mornings.冷天的早晨很难把汽车发动起来。
get sth. going实际上是get + n./pron.+ -ing结构,意为使某人(某物)正在做某事,发生某
情况,动词-ing形式作宾语补足语。如:
The lecture soon got us thinking.报告使我们反复思考。
How can we get things moving?我们如何才能使事情有进展?
We got him talking about his war experiences.我们要他谈自己的战争经历。
11.现在完成进行时由have/has + been + -ing形式构成,表示从过去某一时间开始一直延续到现
在的动作,这动作可能刚结束,也可能会继续下去,并可能延续到将来。如:
I’ve been sitting here for half an hour.(相当于:I sat down here an hour ago,and
I’m still sitting here.)我在这儿坐了有半个不时了。(半小时前开始坐在这儿,现在仍坐着)
They have been studying French since they came to this school.(相当于:They began to
study French when they came to this school.They’re still studying French now and will go
on studying French.)他们进校以来一直在学习法语。(从进校开始学法语,现在仍在学,而且将继续
学下去)
但是某些动词如live,study,work,teach等用现在完成时和现在完成进行时的意思差不多。如:
How long have you been living in Beijing?(或者:How long have you lived in Beijing?)
你在北京住多久了?
