一、look forward to
該短語表示“期望;期待”，注意to是個(gè)介詞，所以后接動(dòng)詞時(shí)要采用動(dòng)名詞(即-ing)的形式。如：
We look forward to the return of spring. (我們期待著春天的到來。)
I look forward to paying you a visit next week. (我期待著下星期去拜訪你。)
二、look out
該短語主要表示“留神;小心”，而且經(jīng)常直接用作提示語，單獨(dú)成句。如：
Look out! The pan of milk is bubbling over! (小心!那鍋牛奶溢出來了!)
但是，look out也可以像下面的句子一樣，用作句子的謂語：
Do look out for spelling mistakes when you check your work. (你檢查作業(yè)時(shí)，一定要當(dāng)心拼寫錯(cuò)誤。)
【注意】
當(dāng)look out與of連用時(shí)，不再表示“留神;小心”，而是表示“往外看”。如：
Looking out of the window, I see a lot of children play and yell. (我從窗口往外張望時(shí)，看到許多小孩一面玩耍一面叫嚷。)
三、look up
該短語主要表示“查閱;仰視;看望”。如：
查閱：You can look up this word in the vocabulary. (你可以在詞匯表里查這個(gè)詞。)
仰視：He lay on his back and looked up at the sky. (他仰臥著觀看天空。)
看望：I shall certainly look up all my old friends when I go back home. (我回家的時(shí)候，當(dāng)然要去看望我所有的老朋友。)
【注意】
當(dāng)look up與介詞to連用時(shí)，表示的是“尊敬;敬仰”。如：
The children all look up to the baseball player. (這些孩子都很敬仰那名棒球運(yùn)動(dòng)員。)
