look

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)共同的意思是“期待,等待”。它们的区别是：
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”。它们的区别是：
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 read- ing 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。
