 assail 指"猛烈连续地攻击", 如:

 assault 语气比 assail强, 指"突然猛烈地进攻", 暗示"武力的直接接触" (如肉搏等), 也有"暴力"的意思, 如:The enemy assaulted us at dawn. 敌人在黎明时向我进攻。

 charge 指"冲击"或"骑兵的突然攻击", 如:

 beset 指"围攻", 即从各个方向攻击, 如:

17 at the age of/by the age of  at the age of表示“在……岁时”,后面接基数词,强调某一时刻的情况或动作,用于一般过去时,作时间状语。例如:

 by the age of表示“到……岁的时候”、“在……岁以前”,后面接基数词,强调到某一时刻为止的结果,用于过去完成时或将来完成时,作时间状语。例如:

18 at the time; at that time; at one time; at a time

 at the time通常用于过去时句子中,指某件事情发生的“当时”、“那时”。例如:

Many people saw the strange thing happen at the time. 当时,许多人都看到了这件奇怪的事情的发生。

 有时,at the time的后面可接“of...”短语。这时,它表示“在(某事态)发生的时候”或“在……的时代”。例如:

Were you in San Francisco at the time of the big earth quake in 1989﹖

1989年旧金山发生地震时,你在那里吗?

It happened at the time of King Alfred. 事情发生在阿尔弗雷德国王时期。

 at that time 则通常指前文明确提到的某个时期、时候。通常其后不带“of...”短语。例如:

(=At the 17th century) the land along the Changjiang River was becoming very crowded.

 at one time=during a period of time in the past意为“过去有一段时期”,“曾经”。例如:

 at a time则意为“一次”,表示一个时间单位。它常与表示数量的词语连用,表示频率。例如:

19 at ... speed / with ... speed at the speed of或者at ... speed,意为“以……的速度”。而当speed被all, lightning, great等修饰时,介词应用with。我们可用一句口诀来帮助记忆:都(all)以闪电般(lightning)大(great)的速度行驶。如:

Our car was running with all speed on the expressway. 我们的车在高速公路上全速行驶。

The Long March No.2 Rocket sent up the satellite into space at the speed of 11.2 kilometers per second. 长征二号火箭以每秒钟11.2公里的速度将卫星发射到太空。

B

20 because/since/as/for

这四个词都是表示原因或理由的连接词,但是as,because,since是从属连词,引导原因状语从句,for是并列连词,所引导的不是原因状语从句,而是表示理由的对等句子,是对前面所讲内容补充和说明。在语气上由强至弱依次为because→since→as→for。because引导的从句多置于句末,表示直接的原因或理由,表示产生那种结果的必然的因果关系,在回答why的提问时,必须用because作答。

如:We stayed at home because it rained.因为下雨我们呆在家里。

 as与since引导的从句多置于句首,不过as表示十分明显的原因,只说明一般的因果关系,可译为“因为、由于”;而since则表示稍加分析、对方已知的原因,一般可译为“既然”。如:

As he was not feeling well,I decided to go there alone.由于他身体欠佳,我决定独自去那里。

Since everyone is here,let's start.既然大家都到了,咱们就开始吧。

 for引导的从句一般放在句末,其前用逗号,它所叙述的理由是间接的,即推测性理由,或是对前面叙述的事实或看法的补充说明。如:

There must be nobody in the classroom,for the light is off.

教室里一定没有人,因为灯灭了。(推测性理由)

 believe;believe in

 believe作及物动词时,其后可跟名词,表示“相信”;后接从句或复合宾语时,表示“认为;料想;相信”等。如:

I believe what he says.我相信他的话。

I believe that he will succeed.我相信他会成功的。

 believe in 是一个动介型短语动词,表示“信奉;信仰”(指对某种思想、主张、观念、行动具有信心)和“信任(have trust in)”。如:

They believe in God.他们信仰上帝。

I believe in having plenty of exercise.我相信多锻炼有好处。

 believe和believe in后均可接表示人的名词或代词,但含义不同。试比较:

I believe in him(I think he is a frustworthy man).我信任他。

I believe him.(I believe what he says).我相信他的话。

21 belief faith trust confidence 都含有“相信”的意思。

 belief 指“承认某事是真的, 尽管有或没有确凿的证据”, 如:

belief in ghosts. 相信有鬼。

 faith 指“认为有确凿证据或道理而完全相信”, 如:

I have faith in his ability to succeed. 我相信他有成功的能力。

 trust 指“信赖”、“信任”, 含有“坚定的信念”的意思, 如:

 confidence 指“在有证据的基础上相信”, 也常指“自信”、“有把握”, 如:

She has great confidence in her success. 她对自己的成功充满信心。

22 besides;except;but  三者都可以用作介词。用于肯定句中时,except/but意为“除……外(不再有)”;besides意为“除……外(还有)”。请比较:

All of them have seen the film except/but Wu Dong. 除了吴东外,他们都看过了那部影片。

All of them have seen the film besides Wu Dong. 除了吴东看过那部影片外,他们也都看过了。

 except后接名词、代词、-ing或不定式时,可以与but互换;except后接副词、介词短语时,一般不能为but所替换。如:

I’ll do everything except/but cook. 除了做饭,我什么事情都干。

This window is never opened except in summer. 除了在夏天,这个窗子从不打开。

 用在否定句中,三者可以互换。如:

除了你,没人能做这工作。

23 be anxious to; be anxious for; be anxious about ;be anxious that be anxious to表示“急于”、“渴望”,其中to是不定式符号,后面接动词原形;

 be anxious for表示“渴望”,后面接名词或代词时,强调渴望得到某物或渴望了解某事;后面接sb.to do sth.时,表示“渴望某人能做某事”,其中for sb.to do sth.是不定式复合结构。
