seem的用法

seem用作表语、接连仿物用于此导从句作表语、可用于转移否定句型等。

1、seem表示“感觉”时可接“to be+名词或形容词”、介词短语、动词不定式、现在分词、过去分词作表语。

2、seem还可接连词that或连词短语as if〔though〕引导的从句作表语, as if〔though〕的从句常用陈述语气, that从句可用于陈述语气,也可用虚拟语气。此时主语多为非人称代词it。历大庆

3、在含有seem的句子中,有时可插入to sb。为了强调,有时to sb 可移至句首。

4、seem还可用于存在句中, seem的主语可为名词、代词或动词不定式(多为to be), seem的形式要与其后的主语一致。

5、在美式英语中seem常用于转移否定句型。

一．seem常常和不定式，形容词，分词，名词和介词短语搭配。如:

1．seem+不定式（短语）

a)I seemed to hear a voice in the distance .

b)Your advice seems to be doing me a favor .

c)I seem to have caught a cold .

注意：1seem后跟不定式（短语）时，要注意不定式所表示动作发生的时间，以此来确定不定式的时态。

2seem后不定式的否定式习惯上用 don’t 来代替，（放在seem 前），如：

You don’t seem to be quite yourself today ( =You seem not be quite yourself today )

2.seem +形容词

a) She seems quite happy today.

b) The enemy seems powerful but in fact it is weak.

[注]此句式出可看作是seem+to be+adj句式的一渣码种简化形式。

如例a可转换为：

She seems to be quite happy today.

例b可转换为：

The enemy seems to be powerful but in fact it is weak.

但目前由于英语的发展，seem+to be+形容词结构的用法已越来越少，seem+adj的结构已趋成型，属口语语体。

3．Seem+分词

a) The situation seemed quite encouraging.

b) The news seems exciting.

c) They seems interested in the film.

[注]seem后用现在分词还是过去分词取决于分词本身的逻辑主语，如句中的主语（盍作的执行者）是分词的逻辑主语，用现在分词，反之用过去分词。

4、seem+名词

a) She seems a clever girl.

b) Her mother seems a teacher.

c) It seemed a long time before my turn came.

5.seem+介词短语

They seemed in high spirits.

二、seem常用于it作形式主语的“It seems/seemed that……”结构，如：

a) It seems that you were lying.

b) It seemed that he had been a scientist.

c) It seems impossible that he will be here tomorrow.

[注]1）在这一句式中，常省去that，如例a可改为：

It seems you were lying.

2)间或在seem后老梁好可跟一形容词，如例c.

三、seem常用于由as if/though引导的从句中，如：

a) It seems as if it is going to rain.

b) It seems as though our plan’ll be perfect.

c) It seems as if he knew nothing about that.

d) It seems as if it was/were spring already.

[注]在这种句式中，如从句所叙述的情实现的可能性比较大，从句侍铅谓语用陈述语气

，如a,b两例；若实现的可能性较小，或根本不可能实现，从句的谓语则用虚拟语气，如c,d 两例。

四、seem通常用在“It seems(seemed)to sb(that)……”的结构中，这种结构常用来表示“行为”的主体，例：

a) It seems to us a good chance.

b) It seems to the emperor that the people were right.

c) It seems to me eveyythingis all right.

五、seems也常用在“there seem(s) to be”句式中，用来代替be，作句子的谓语。如：

a) There seems to be no point in refusing.

b) There seemed to be something the matter with him.

c) There doesn’t seem to be too much hope of our team beating theirs.

[注]1）在这一结构中，seem表示“似乎有”、“看来”的意思，如：

There seem to be a lot of things to do .(=It seems as if there were a lot of things to do.)

2)There seem(s) to be +n”这个结构的否定形式为“There seem(s) to be +no+n.”（如例a）或（“There doesn’t seem to be +n.”（如例c）.

六、seem有时也同人称代词I连用，意为“感到好像、觉得似乎”等意，如：

a)I seem unable to solve it right now.看来我无法立刻解决它。

b)I seem to have seen him somewhere before.我好像以前在什么地方见过他。

七、seem还常常同like搭配。如：

[注]这种句式表达的意思同“seem+to be +n.”结构表达的意思基本相同，故两种句式可替换，如：

The girl seems like a bird/to be a bird.
