高三英语第一轮模拟考知识点1

1. 对在句中作时间、条件、原因还是别的状语不是很清楚。

2.分不清何时用现在分词、何时用过去分词。

解决办法：

1.理解分词作状语时可以转换成相应的状语从句。

2.分清何时用现在分词、何时用过去分词。

用法讲解：

1. 分词或分词短语作状语时，可以表示时间、原因、让步、条件，方式或伴随状况。通常可转换成相应的状语从句;表示方式或伴随状况时可以转换成并列句或非限制性定语从句。例如：

Put into use in April 2000 (=When it was put into use in April 2000), the hotline was meant for residents reporting water and heating supply breakdowns. 分词短语作时间状语

Blamed for the breakdown of the school computer network (=Because she was blamed for the breakdown of the school computer network), Alice was in low spirits. 分词短语作原因状语

Given time (=If he is given time), he’ll make a fist-class tennis player. 分词短语作条件状语

We often provide our children with toys, footballs or basketballs, thinking that all children like these things. (= and think that all children like these things.) 分词短语作伴随状语

2. 有时为了强调，分词前可带when, while, if, though, as if, unless等连词一起作状语，以便使句子的意思更清楚、更连贯。例如：

When comparing different cultures, we often pay attention only to the differences without noticing the many similarities.

Though tired, he still continued reading.

3. 现在分词和过去分词作状语时的用法比较。

不管是现在分词还是过去分词单独作状语，其逻辑主语必须与主句的主语一致。分词作状语通常可转换成一个相应的状语从句或并列句，如果状语分句或并列句中的谓语动词为被动结构，就用过去分词;如果状语分句或并列句中的谓语动词为主动结构，就用现在分词。例如：

When compared with the size of the whole earth , the biggest ocean does not seem big at all.

分词部分相当于When the biggest ocean is compared with the size of the whole earth, 主语与分词是被动关系，所以用过去分词。

When comparing it with the size of the whole earth, we find that the biggest ocean does not seem big at all.

When we compare it with the size of the whole earth... 主语与分词是主动关系, 所以用现在分词。

Faced with a bill for,000(=Because he is faced with a bill for,000), John has taken an extra job.

Whenever he was asked why he was late for class, he would answer carelessly, always saying the same thing (= and he would say the same thing).

注意：

1. 现在分词有两种时态：一般式doing和完成式having done。一般式通常表示与主句的谓语动词所表示的动作同时发生或无先后;完成式则强调分词所表示的动作先于谓语动词所表示的动作。如：

While walking in the street, we met some friends of ours.(同时发生)

Having waited in the queue for half an hour, Tom suddenly realized that he had left his wallet at home. (“等待”先于谓语动词“意识到”)

2. 分词的否定式的构成: not +分词。 Not having received a reply, he decided to write again.

高三英语第一轮模拟考知识点3

1. Since从句为非延续性动词的过去时或现在完成时，时间的起点应该从从句动作完成时刻算起。

例如：

Things have changed a lot since I wrote to you last time.

自我上次给你写信之后，情况已发生了很大的变化。

She has lived with us since she has come here.

自从她来到这里，就一直和我们住在一起。

2. Since从句为延续性动词的一般过去时，表示动作或状态的结束。其含义与动词的词义恰好相反，具有否定意味。

例如：

All has changed since he was at home.

自从他离开家以后，这里的一切都变了。

I haven’t written to her since she lived in London.

自从离开伦敦以来，我还没有给她写过信。

He has never been to see me since I was ill.

自从我病愈以来，他一直没有来看我。

Two years have passed since I last smoked.

我戒烟已经两年了。

但如果since从句是延续性动词的现在完成时，则表示动作由开始延续至说话的时候，具有肯定意味。

例如：

He has never been to see me since I have been ill.

自从我生病以来，他一直没有来看我。

She has talked little since she has stayed at home.

自从她呆在家里以后，就很少讲话。

Since we have owned a car， we have gone camping every year.

自从我们有了汽车后，年年都去野营。

3. 在现代英语中，since从句是延续性动词的一般过去时，有时候也可以表示肯定意味。此时，多半用ever来加强since的语义。

例如：

She has known me ever since she was a child.

她从小就认识我了。

I have live here ever since I was born.

我生下来就住在这里。

4. 在it is+时间+since从句结构中，since从句是非延续性动词的一般过去时，含有肯定意味。

例如：

It is three years since her husband left her.

她丈夫离开她已经3年了。

It is over sixty years since the People’s Republic of China was established.

中华人民共和国已经成立60多年了。

5. 在it is+时间+since从句结构中，since从句是延续性动词的一般过去时，含有否定的意味。

例如：

It is three years since she stayed here.

她离开这里已经3年了。

How long is it since you were a league member?

你_有多久了?

6. 在it is+时间+since从句结构中，since从句是现在完成时或过去完成时，均含有否定意味。

例如：

It is five years since we have seen her.

我们已经5年没有见她了。

It was years since I had seen her.

在那之前，我已经有好久没有见到她了。

It’s been a long time since I’ve seen you.

我已经很久没有见到你了。

另外，①根据英语惯用法，since从句不可以否定形式出现。

例如：

It is four years since I have smoked a cigarette. 我已经4年不抽烟了。

不可说：It is four years since I haven’t smoked a cigarette.

但由于下句中的since不作“自从”解，所以从句可以用否定形式。

例如：

I haven’t been out anywhere since I don’t know how long.

也不知多久了，我哪儿也没去过。

②Since从句通常不与非延续性动词的现在完成时的肯定式连用。

例如：

Her mother died when she was a child.

她小时候母亲就去世了。

不可说：Her mother has died since she was a child.

③Since前不可加表示时间的词语，但可以与ago连用。

例如：

She has lived with us since her mother died three years ago.

自从她母亲3年前去世，她就一直和我们住在一起。

不可说：She has lived with us three years since her mother died.

④在It was five years ago since his father died. 一句中的since用错了，因为在含有ago的时间范畴里，已经有了从过去的一个时间点以来的时间，即已有了since的时间范畴，所以再用since是多余的。

改为：

It was five years ago that his father died.

他父亲5年前去世了。

It is five years since his father died.

他父亲去世已经5年了。
