to是英語中常見的介詞，有到，向，關(guān)于，朝一個方向的等意思。下面小編整理了一些to的用法，供大家參考！

介詞to有哪些用法

在英語中to的用法是比較重要的，一般來說 to 有兩種基本用法：

1.做介詞，表示“到，向，往”，如go to，fly to，后面跟名詞作定語，構(gòu)成介賓結(jié)構(gòu)。

2.動詞不定式的標(biāo)志，很常見的，如：want to do，be happy to do。

注意有一些看似不定式但實為介詞的結(jié)構(gòu)，如 look forward to，pay attention to ，他們后面跟動詞的ing 形式作賓語，千萬不能跟原形。

其他的如to +do 作定語等等基本都是以上兩種用法的延伸。

to和too用法有什么區(qū)別

to有：1.從哪里,到哪里.2.事情的狀態(tài)傾向哪一方.3.表示幾個物體相比較的意思.通常用在與原形動詞一起構(gòu)成的動詞不定式.

too有：1.也.2.太,非常.3.過分的意思.通常用在與名詞一起構(gòu)成的極端情況下.

所以，這兩個詞只是讀音相同,用法上沒有什么相同點。
