冠词的用法专项讲解

今天我们来学习Seem 的用法 ，快来一起学习吧。下面小编就和大家分享，来欣赏一下吧。

Seem 的用法

Seem 意为「似乎，好像，看起来」，仅能当连缀动词用，其后接形容词 (或名词 - 接名词的情况比较少见) 来做主词补语，本身通常不用进行式。例如：

Tom seemed slightly embarrassed to see me in the nightclub. (汤姆在夜店看到我好像有点尴尬) - 接形容词。

Mary seems very happy with her new boyfriend. (玛丽对她的新男友似乎很满意) - 接形容词。

Mary is seeming very happy with her new boyfriend. (误) - 不可使用进行式。

Buying a new computer seems a complete waste of money to me. A used one would be just as good. (买新电脑对我来说完全是浪费金钱。二手电脑就好了) - 接名词 (片语)。

Seem 后面经常接「to + 塬形动词」的不定词结构，或者接「to + have + P.P.」的完成式不定词结构来表示该完成式动作或状态比 seem 还要早发生或出现。例如：

She would always seem to offend people. (她过去似乎老是得罪人)

Teresa seems to know more about me than my wife. (泰瑞莎似乎比我太太更瞭解我)

Cindy seems to have gone out. (辛蒂似乎已经外出了)

The professor seemed to have mistaken me for someone. (教授看来好像把我误认为某人)

Seem 的否定形式有两种，—是将否定词放在 seem 之前，另一是将否定词放在 seem 后面的不定词之前，但意思一样。例如：

The president seems not to like the plan. (总统似乎不喜欢这项计画)

= The president doesn’t seem to like the plan.

They seem not to be at the dormitory. (他们似乎不在宿舍)

= They do not seem to be at the dormitory.

除上述外，seem 还有下列几种常见的句型：

There seem(s) to be 或 there seemed to be + 名词 (片语) - 注意：Seem 的单复数与名词一致

There seem to me to be two possibilities. (= I think there seem to be two possibilities.) (我觉得有两个可能性)

There seems to be something wrong with her. (她似乎有点不对劲)

There seemed to be a mistake in these calculations. (这些计算似乎有错)

Seem + as if/as though/like 所引导的子句 (like 后面亦可接名词或名词片语)

Dad seemed (as if/as though/like he was) tired. (爸爸好像累了)

It seems as if they’re no longer in love. (他们似乎不再相爱了)

Sam seemed as though he was a bit detached. (山姆似乎有些心不在焉)

It seems like their marriage is over. (他们的婚姻好像结束了)

- 这句与 It seems that their marriage is over. 的意思相同，但大多用于非正式场合或口说英语。

It doesn’t seem like a good idea to lend money to John. (借钱给约翰似乎不是个好主意)

It seems 或 it seemed + that 所引导的名词子句 (连接词 that 可以省略)。在此一句型中，seem 后面可接介系词 to + 人来表示「某人感觉好像，某人觉得似乎」的意思。例如：

It seems (that) he is a good guy. (他似乎是个好人)

It seemed (that) he had changed his mind. (他似乎已改变心意)

It seemed to everyone (that) Linda was wrong. (大家都觉得琳达似乎是错了)

= Everyone thought (that) Linda was wrong.

It seems to me (that) it will rain tonight. (在我看来，今晚会下雨)

= I think (that) it will rain tonight.

在 it seems 或 it seemed + (that) 名词子句的句型中，名词子句的否定词可转移到主句中;进一步而言，主句的否定词係否定名词子句的动词，不是否定 seem。例如：

It seems that they don’t know how to deal with the situation. (他们似乎不知道如何处理这种情况)

= It doesn’t seem that they know how to deal with the situation.

It seems (that) Peter can’t come. (彼得好像不能来了)

= It doesn’t seem (that) Peter can come.

It seems to me (that) Richard isn’t the right person for the job. (在我看来，理查不是这项工作的合适人选)

= It doesn’t seem to me (that) Richard is the right person for the job.

= I don’t think (that) Richard is the right person for the job. - think、believe 等动词后面的名词子句也是否定转移。

wish hope 的用法小结

wish和hope都有“希望”的意思，但它们的用法不同。

1、wish 意思是“ 希望，想要，但愿”，常表达一种虚拟语所，指“想要不可能的事情”或“也许可能，但跟实际有差异”。后跟代词、名词或不定式作宾语。wish跟从句时常用虚拟语气。也可用于祝贺语中。

如：

1). I wishto see the manager .

我想见到那个经理。

2). I wish him to look at this .

我希望他能看看这个。

3). I wish I could fly .

我希望我能飞。

2、hope 意思是“希望” ，指相信有可能达到或实现的愿望，后常跟动词不定式或that 从句，但没有hope sb to do sth这种用法。

如：

1). I hope to go to America next month .

我希望下个月去美国。

2). I hope that they get here soon.

我希望他们能尽快到这里。

拓展：

1、expect 意思是“期待，盼望”，后跟名词、代词或动词不定式作宾语，但不能接doing。如：

I expect to work with you some day .

我期待着有一天和你一起工作。

2、look forward to 意思是"盼望，期待“，后跟名词、代词或动名词，不能接不定式。

如：

I look forward to hearing from you.

我盼望收到你的来信。

重点语法情态动词shall的用法

1)用于第一人称征求对方的意见。

如：

What shall I wear on the journey?

我路上穿什么好呢?

Shall we dance?

我们跳舞好吗?

2)shall 用于第二、三人称时表允诺，警告，命令，威胁(现已少见)。

如：

She shall get her share.

她可以得到她的一份。

You shall have it back tomorrow.

你明天可以将它拿回。

情态动词should一般不应被认为是情态动词shall的过去式，主要用法有：

1)用于第一人称疑问句中询问对方的意愿，但语气较委婉温和。

如：

What should we do now?

我们现在该怎么办?

2)表示应该、必须，常与must 换用。

例如：

We should (must) master a foreign language at least.

我们应当至少掌握一门外语。

3)“should+be+表语”的结构，表示推测或惊奇。

例如：

They should be back by now.

他们现在应该回来了吧。

I am sorry that she should be so careless.

我感到遗憾她竟会那样粗心。

4)“should+have+过去分词”的结构，表示过去该做而实际上尚未做的动作或行为;其否定则表示发生了不应该发生的行为。
其同义结构“ought to have +过去分词”,表示过去“早应该”、“本当”之意，语气较强。

例如：

I should have thought of that.

这一点我是应当想到的。(但没想到)

They should not have left so soon.

他们不应当走得这么早。(但已走了)

5) 在“It is natural (strange, natural, necessary, surprised, impossible, important ) that……”句型中，主语从句中的谓语动词要用should +动词原形”表示“理所当然”、“奇怪”、“必要”、“惊异”等的意思。在lest(以免)、for fear (that) (以防)、in case(以备万一)等之后也要用should+动词原形;在advise, sugest, order, demand, request 等的从句中should+do”

例如：

It is necessary that he(should) be sent there at once.

有必要马上派他到那里去。

It is strange that he should say so.

他会说这样的话真是奇怪。

Let us go at once lest we should be late for the train.

我们马上走吧，以免赶不上火车。
