有点儿像，多少有几分……。如：

He is a bit of a poet. 他多少有点儿像诗人。

He is a bit of a coward. 他多少有几分怯懦。

微不足道的。如：

We’re having a bit of a party next week. 下个星期我们准备

请几个客人小聚一次。

相当数量的，相当规模的，有一定困难的。如：

The humor of it takes a bit of finding. 这其中的幽默非仔细体会不可。

This new system takes a bit of getting used to. 这个新的制度要适应有一定困难。

英语四级语法用法辨析：a bit和a little的区别

有本教辅书上讲：a bit和a little是一对同义词，可以互换使用。但我最近碰到这样两个句子：

① Im not a bit tired, so I neednt have a rest.

② Toms mother couldnt sleep well recently. She was not a little worried about Toms health.

两个词组在加了not后，意思好像大不相同，请问这是怎么回事?

a bit和a little 在意思上非常相似，都表示“一点点，有点儿”之意。它们用作副词，表达“程度”时，修饰动词、形容词、副词、介词短语或比较级，意思相同，可以互换。例如：

He is a bit like his father.

He is a little like his father.

他有点像他的父亲。

The speaker spoke a bit louder in order to make himself heard more clearly.

The speaker spoke a little louder in order to make himself heard more clearly.

讲话人把嗓门提高了一点儿，以便让别人听得更清楚。

但是，在下列情况下，它们是有区别的：

1. 当它们用作定语，表达“数量”时，a bit后要加of，a little 则不用。例如：

She ate a bit of bread for lunch.

She ate a little bread for lunch.

她午饭就吃了一点点面包。

2. 但是，一旦否定，not a bit 和not a little的意思就大不一样了，甚至相反。

not a bit 意思是“一点也不”，相当于not at all，not in the least 之意。例如：

He is not a bit like his father.他一点也不像他父亲。

Are you hungry? --- No, not a bit. 你饿了吗? 不，一点也不饿。

She is not a bit happy.她很不开心。

not a little意思是“非常，很”，相当于very (much), a lot 之意。例如：

He is not a little like his father.他很像他的父亲。

I am not a little surprised at the news. 我对这个消息深感惊讶。

The boy was not a little worried because he hadnt heard from her parents for a long time. 那个男孩很担心，因为好久没收到父母的来信了。

【注意】有时bit之前，还可以加little，进一步修饰程度之低，如：

Im a little bit tired. Lets take a short rest. 我稍有点累了。让我们休息一会儿

英语语法：副词短语a bit, above all的用法

1. a bit有点儿

用法：a bit通常修饰形容词或者动词。需要注意与a bit of 的区别，a bit of是形容词词组，表示“少量的，少许的”，常修饰不可数名词。

例句：Could you tell me a bit about the business your company is doing? (20XX年12月四级)

你们公司正在做哪些业务，你能告诉一点儿吗?

结构分析：you是主语，could tell是谓语，me是间接宾语，a bit about the business是直接宾语，your company is doing 是后置定语从句，其中your company是主语，is doing是谓语(现在进行时，表示公司现在正在做的业务)，the business是宾语。

2. a moment ago刚才

用法：a moment ago通常与一般过去时态连用，表示某个动作刚刚发生，类似的词组还有just now等。

例句：The man who fainted in the street was sent to the hospital a moment ago.

那个晕倒在大街上的男人刚才被送医院了。

3. above all首先，首要的是

用法：above all起强调作用，一般放在句首或都句中。

例句：Above all, you should attach more significance to the well being of the children.

首先，你要更加重视孩子们的生活。

一般过去时与现在完成时的用法区别

一般过去时与现在完成时区别专题 一、前言： 初一下学期同学们学习了一般过去时态的相关知识，即将到来的初二上学期英语学习中，现在完成时是重要的学习内容。本文通过对比一般过去时和现在完成时，对现在完成时进行初步讲解，希望使同学们读新学期的学习有所准备。 二、现在完成时 1. 现在完成时的构成 现在完成时是由助动词have (has)+动词的过去分词构成。助动词说明该谓语是属于现在时范围。它和主语的人称、数要保持一致。过去分词是主要的谓语动词，说明句子的意义。 2. 现在完成时的用法 现在完成时表示过去某时发生的行为对主语目前产生的影响。即用过去发生的某个行为来说明现在的某种情况。 We are good friends.(现在的情况） I knew him in 1997.（过去的动作） We have known each other since 1997. （现在完成时把过去的动作和现在联系起来并着眼于现在） （1）表示动作发生在过去某个不确定的时间，但对现在留下了某种影响和结果。常被just、already、yet 等副词修饰。如： -Have you had lunch yet? -Yes, I have. I've just had it. 你（已经）吃午饭了吗？我刚刚吃过。（现在我不饿了） （2）表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止，可能仍然在进行。常带有for和since等表示一段时间的状语。 如：He has taught here since 1981 他自1981年就在这儿教书。（可能还要继续教） I haven't seen her for four years. 我有四年没见到她了。 （3）表示说话前发生过一次或多次的动作，现在成为一种经验，一般译为汉语“过”，常带有twice,ever, never,three times等时间状语。 如：I have been to Beijing twice.我去过北京二次。 3.现在完成时的时间状语 （1）现在完成时属于现在时范围，故不能和过去的时间状语连用。如：yesterday,last Sunday,in1990,three years ago等。但是，在强调动作产生的后果和影响时，可以和一些表示不确定的时间状语连用。 a. 用副词already和yet。already一般用于肯定句中，yet一般用于否定句和疑问句中。 如：We have already finished our homework.我们已完成作业了。 They haven't finished their homework yet.他们还没有完成作业。 b.用ever 和never。多用于否定或疑问句中，表示“曾经”或“从未“等。 如：-Have you ever been to the Great Wall? 你曾经去过长城吗？ -I have never been to the Great Wall.我从未去过长城。 c.用表示到说话为止的过去时间状语，如just, before, up to now, the past few years等。 例如：I have seen her before, but I can not remember where. 我以前见过她，但记不起在哪里见过。

四种花费用法讲解

Take\spend\pay\cost表示花费的时候用法1、It takes sb some time to do sth. 该句型只表示花费时间，it是形式主语，真正的主语是动词不定式。sb是宾格形式，some time 是一段时间。 Eg： a.It took the boys two weeks to plant the trees last spring. b.It takes me ten minutes to walk to school every day. c.It will take us about 30 minutes to finish listening the story. 2. Sb spends some time/money (in) doing sth. Sb spends some time/money on sth. 该句型可表示花费时间，也可以表示花费金钱。主语必定是人，做某事可以用动词表示，也可用名词表示。 d.We spent the whole day going hiking in Mount Tai last summer. e.Did you spend ten yuan on the pen? f.All the boys spent about five minutes

remembering the ten English words. 除此之外，还有pay和cost也可以表示花费金钱。 Pay 常用for连用，构成pay for 意思是赔尝、付款。主语必须是人。 I paid for the book yesterday. 昨天我买了这本书。 I paid ten yuan for the book yesterday. 昨天我花了十元钱买了这本书。 You should pay for the book if you lose it. 如果你丢了这本书，你就应该赔偿。 Cost 表示值多少钱，也表示花费。 The magazine costs twenty yuan. The bicycle cost me eight hundred and fifty yuan.
