下面小编给大家整理的seem的用法总结，本文共13篇，希望大家喜欢!
篇1：seem的用法总结
此时seem为连系动词,后直接接形容词或to be+形容词或名词(短语)作表语,以说明主语的特征或状态。如:
Tom seems (to be)a very clever boy. 汤姆看上去是一个很聪明的男孩。
Everything seems easy.一切似乎很容易。
注意:afraid,asleep,awake等表语形容词不能直接跟在seem 之后,必须和seem to be 连用,如:They seem awake.(误)应改为:They seem to be awake.
“主语+seem +不定式(或不定式的完成式)”
此句型中的`seem 用作不及物动词,不用在进行时态中,其与不定式一起构成复合谓语(不定式作宾语)。如:
a. The moon seems to change its shape. 月亮好像在变换形状。
b. I seem not to be able to make him happy. 我似乎不能使他高兴起来。
c. They seemed to be eating something. 他们好像在吃什么东西。
d. I seem to have caught a cold. 我似乎已经感冒了。
注意:seem 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,如例c、d;seem 后不定式的否定式习惯上在seem 前加don’t ,也可以用seem not to...,如例b也可以说成:I don’t seem to be able to make him happy.

篇5：Seem的用法总结
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。

篇6：there seem to be用法及例句
引证用法不同
1、there seem to be：seem的`基本意思是“好像”“似乎”，指根据某迹象按照自己的主观印象、看法作出的主观判断或个人推断，虽然有一定的根据，但并不一定是事实。
2、there seems to be：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。在接名词作表语时，如名词前有形容词修饰。
篇7：seem的用法是什么？
seem 是连系动词,意为“似乎”、“好像”、“看上去”,用来表示说话人内心的?有一定依据的推测、判断或猜想。其用法如下:
一、“seem(to be) +n(作表语)”,此结构中的 to be 可省略,但名词前一般应有形容词修饰:

It seemed(to be) an interesting book. 这好像是本有趣的书。
二、“seem(to be) + adj(作表语)”,此结构中的 to be 也可省略?如果 to be 后面是 afraid, asleep, awake 等表语形容词,则 to be 不能省略:

seem的5个考点用法，有2个你可能不知道哦!
在初中英语中seem是一个常见的单词,也是一个重要的考点单词。小编根据多年的教学经验总结,发现seem有五个用法。 seem可用作连系动词或不及物动词，意为“似乎;好像”，其常见用法现归纳如下：
一、主语+seem+形容词，表示主语似乎.……(怎么样)。The boys Seemed hungry when I saw them.我看见这些男孩的时候，他们似乎很饿。
The problem seems easy,but it's so difficult.这个问题似乎很容易，但却很难。
二“主语+ seem +(to be )+表语”，表语多为名词或形容词，有时是其他的词或短语，以说明主语的特征或状态。例如：
Jenny seems (to be ) a very clever girl. 珍妮看上去是一个非常聪明的女孩
The man over there seems to be a history teacher. 那边的那个人看上去像一个历史老师。
Mr. Brown seemed to be quite unhappy. 布莱克先生好像十分不快乐。
This small town seems changed a little. 这个小城镇似乎有点儿变化。
三、“主语+ seem + 不定式”，此句型中的seem与不定式一起构成复合谓语。例如：

The children seemed to enjoy themselves in the new museum.孩子们似乎在新的博物馆里玩的很开心。
The young men seem to have changed a lot over the years. 这些年轻人近年来看起来变化很大。
四、“It seems + that从句”，其中it 是形式主语，that引导主语从句。

It seems that Mr Brown doesn't like his job very much.好像布朗先生不是很喜欢她的工作。
五、“There + seem to be +名词”，其中to be 可省略。seem 的单复数形式要根据后面作主语的名词的单复数形式而定。例如：
There doesn’t seem to be anything interesting in the newspaper.报纸上似乎没什么有趣的东西。
There seems no need to stay there for so long 看来没有必要呆在那里那么久了。
英语中的“好像”——seem和look的用法
seem/look
1)二者都可以作“看起来”讲，但seem暗示凭借一些迹象作出的有根据的判断，这种判断往往接近事实;look着重强调由视觉得出的印象。两者都可跟(to?be)+形容词和as?if从句。
He seems / looks (to be) very happy today. 他今天看起来很高兴。
It looks (seems) as if it is going to rain. 好像要下雨了。
2)但下列情况中只用seem不用look：
1)后跟不定式to do时。
He seems to know the answer. 他似乎知道答案。
2)在It seems that?...结构中。
It seeems that he is happier than yesterday. 他看起来比昨天高兴些了。
名词可数与不可数的“相对论”
所谓可数与不可数的“相对论”，即是指一个名词是可数还是不可数关键在于它所表达的意义，而意义又随语境的不同而改变，因而名词的可数性是与它所使用的上下文语境密切相关的。同样一个名词，会因为在不同的语境中含义不同而导致它的可数性不同，因而不能孤立地来看待名词的可数性。这是有关名词可数性的重要理念。简言之，名词的可数性重在意义而不是形式，与使用的语境有关，意义和语境的不同会导致名词的可数性不同，这就是名词可数性的“相对论”。为了让读者能够深刻地理解这个名词可数性的理念，笔者这里给大家看下面这篇短文。短文是有关食物营养方面的，请读者关注其中food的单复数及其含义的变化：
1
Eating for Energy
Do you know anything about this food pyramid? What does it show?
Many professional sports teams have recently added a new member to their organization—a nutritionist. That's because athletes have become aware that food affects performance. You don't have to be an athlete to notice this effect. If you've ever skipped breakfast and then tried to clean the house, you know that you need food for energy. Here are some tips about eating to increase your physical performance:
Eat enough food. Your body needs a certain number of calories each day. If you're too thin, you'll often feel tired and you'll be more likely to get sick.
Read the labels on food products. This information will tell you how nutritious the foods are.
Avoid eating foods that are high in simple carbohydrates, that is, sugars. A chocolate bar will first give you energy, but then it will leave you feeling even more tired.
Eat a balanced diet, one that includes complex carbohydrates, protein, and fat. Use the food pyramid to help you decide how much to eat of each type of food. Complex carbohydrates provide the body with “fuel”. They are found in fruits and vegetables, and in bread, rice, pasta, and other foods made from grains. The body uses protein to build muscles, and it uses fat to absorb the vitamins in food. Protein and fat are found in foods like milk, cheese, meat, fish, and eggs. Too much fat, however, can be harmful.
精品译文
科学饮食，摄取能量
你了解食物金字塔吗?它有什么内容?
很多专业的运动队现在都已增添了一名新成员——营养师，那是因为运动员们已经意识到饮食会影响他们的运动成绩。作为一名普通的读者，你不必非得是运动员才能感受到这样的影响。比如，若是你某天没有吃早饭就开始打扫房间，你就会知道你需要吃东西以增加体力。下面的一些小贴士告诉你该如何科学地饮食来增强体力：
饮食要足量。你的身体每天都需要一定的热量。如果你太纤瘦，你就会常常感觉疲倦，因而更易生病。
仔细阅读食品标签。因为它会告诉你该食品的营养成分。
不要吃那些富含单糖类的食物，也就是各种甜食。比如吃巧克力，刚开始会增加你的能量，但是过后它会让你感觉更疲倦。
均衡饮食。饮食中要包括多糖类食物、蛋白质和脂肪。可以利用食物金字塔来帮助自己决定每样食物该吃多少。多糖能够提供给人体“燃料”，它们富含在水果、蔬菜、面包、米饭、面食以及其他谷物类食物中。我们人体要利用蛋白质生长肌肉，利用脂肪来帮助吸收食物中的维生素。蛋白质和脂肪常见于牛奶、奶酪、肉类、鱼类以及蛋类等食物中。不过要注意，太多的脂肪也会有害。
以上这篇短文中共有12处food，读者也看到了，其中有food和foods两种变化。这也就意味着其中的food有时作为不可数名词，有时作为可数名词，因而有了复数的foods。我们现在来详细分析比较这12处food的含义和可数性。

这里的第一个food作定语，修饰products，是表示“食物”这个总称的、抽象的概念，而不是表示不同种类的、具体的食物，因而作为不可数名词。第二个foods则是指代上文中的food products，表示“各种食品”，这种指代关系我们可以从foods前面的定冠词the看出来(the修饰一个复数名词时必然表示特指，即上文出现过的内容)，所以我们在上面的译文中把the foods译成了“该食品”，以示指代food products。在这样的上下文语境中，这里的food转化为一个可数名词，因而要添加-s变为复数。
6) Avoid eating foods that are high in simple carbohydrates, that is, sugars. A chocolate bar will first give you energy, but then it will leave you feeling even more tired.
妙语点睛
这里的food不是表示“食物”这个总称的、抽象的概念，而是表示不同种类的、具体的食物，这一点可以从下文的sugars这个复数名词看出来。我们知道，sugar若是作为“糖”这种物质来理解的话，应该是一个不可数名词，属于上述第二组Group B里的名词，但在这里是表示“各种糖类食物”，因此我们在上面的译文中把sugars译成了“各种甜食”(所以下文中出现了a chocolate bar这样甜食的例子)，因而也转化为可数名词。在这样的上下文语境中，为了配合sugars，这里的foods也转化成了一个复数名词，表示“不同的食物”。
7) Use the food pyramid to help you decide how much to eat of each type of food.
妙语点睛
这里的第一个food作定语，修饰pyramid，是表示“食物”这个总称的、抽象的概念，而不是表示不同种类的、具体的食物，因而作为不可数名词。第二个food也是表示“食物”这个总称的、抽象的概念，然后通过each type of这个短语来表示食物的种类。
8) They are found in fruits and vegetables, and in bread, rice, pasta, and other foods made from grains.
妙语点睛
这里的food不是表示“食物”这个总称的、抽象的概念，而是表示不同种类的、具体的食物，这些具体的食物包括上文提到的fruits, vegetables, bread, rice和pasta。在这样的上下文语境中，这里的food转化为一个可数名词，因而要添加-s变为复数。
9) The body uses protein to build muscles, and it uses fat to absorb the vitamins in food.
妙语点睛
这里的food是表示“食物”这个总称的概念，泛指任何食物，因而是不可数名词。
10) Protein and fat are found in foods like milk, cheese, meat, fish, and eggs.
妙语点睛
这里的food不是表示“食物”这个总称的、抽象的概念，而是表示不同种类的、具体的食物，这些具体的食物就是下文提到的milk, cheese, meat, fish和eggs。在这样的上下文语境中，这里的food转化为一个可数名词，因而要添加-s变为复数。
从以上的详细分析中，读者应该看到了，food所使用的上下文语境对其含义及可数性有重要影响。比如，在Protein and fat are found in foods like milk, cheese, meat, fish, and eggs. 这个句子里，因为有like milk, cheese, meat, fish, and eggs这样的下文，而使得原本不可数的food转化成了可数名词(foods)。
