look happy
这里look是表感官的系动词（相当于系动词be),这类词叫做半系动词。半系动词后可用名词、不定式、分词和形容词等作表语，这类词有： 1.表感观的系动词：look, sound, taste, smell, feel（这些词用形容词作表语）2.表似乎的系动词seem, appear3.表变化的系动词：become, get, turn, grow, make, come, go, fall, run 4.表依旧的系动词：remain, keep, stay, continue, stand, rest, lie, hold 5.可带名词作表语的系动词：become, make, look, sound, fall, prove, remain, turn（该词后接的单数名词前多不用冠词。如：He turned teacher.）
I look forward to,I am looking forward to
短语look forward to在句中可用于一般现在时,也可用于一般进行时,前者口气较随便,多用在私人信件中;后者口气较正式,常用在公文中。
look for, look forward to, anticipate, expect
这组词(组)的共同意思是“期待,等待”。其区别是:expect指“等待某事发生”,常有一定的根据,发生的可能性较大；anticipate含有“预先体味”的意味；look for是日常用词,也可表示“期待”；look forward to指以欢乐或焦急的心情期待某事发生。例如:
I expect to see some fine films during the holidays.我期望假期能看上几部好电影。
We anticipate that we shall hear from you again.我们预感到将会再接到你的信。
I think we may look for a better result next time.我想下次结果可能会好一些。
I'm looking forward to your visit.我期待着你的来访。
look, appear, seem
这三个词都可用作系动词,表示“看起来”。其区别是：
1.在含义上, appear 强调外表上给人的某种印象,有时含实质上并非如此的意思; look意味着看上去如此,实际亦是如此; seem 则暗示判断有一定根据,这种判断往往接近事实。例如:
He appears to be very young.
他看上去很年轻。(实际上不一定如此)
He looks to be very young.
他看上去很年轻。(实际上也年轻)
He seems to be very young.
他看上去很年轻。(可能他的确很年轻)
2.在用法上,这三个词都可跟形容词或“to be+形容词或名词”结构,也可用于It appears〔appeared〕/looks〔looked〕/seems〔seemed〕 as if...结构。但是, appear 和seem跟to-v时仍表示“看起来”,而look 接to-v则是“盼望”的意思。例如:
He appears〔seems〕 to know it.
他看来知道这件事。
He looks to hear from you.
他期待你来信。
另外, appear 和seem可用于It appears〔appeared〕/seems〔seemed〕 that...结构,而look不能。例如:
我看他似乎很喜欢看这部小说。
[误] It looks to me that he enjoys reading the novel.
[正] It appears〔seems〕 to me that he enjoys reading the novel.
还有, appear 和seem一般不用于进行体; 而look可用现在进行时,这和一般现在时所表示的意思无多大区别。例如:
You are looking〔look〕 very unhappy.你看起来很不高兴。
look, glance
这两个词的共同意思是“看”,都可接介词at。其区别是:glance指匆忙地看一眼,也指粗略地、随便看看、暗暗地看; 而look则表示有意识地注意看,将视线集中于某人或某物上,着重于看的动作。例如:
She felt very nervous with so many people looking at her.这么多人瞧着她,她感到非常紧张。
I found the child opposite looking at my red hat.我发现对面的孩子在看我的红帽子。
look, see, watch
这三个词都有“看”的意思。其区别是:look指有意识的“动作”;see指有意或无意的“结果”;watch则指有意识地以期待、警觉等心情看上一段时间。例如:
We looked but saw nothing.我们看了,可是什么也没看到。
They are watching a TV play.他们在看电视剧。
look for, discover, find, find out, invent
参见discover条。
