動詞不定式
1、to加動詞原形構成一種非謂語形式，在這裡不是介詞，無詞義。
如：I want to make a New Year card. 我想製作一張新年賀卡。
Would you like to have a picnic with us? 你願意和我們一起去野餐嗎？
2、to保留原來動詞的一些特徵，它可以帶自己的賓語和狀語等。
如：To get there faster, you can take bus No.5. 想快一點到那兒，你可以坐5路車。
3、to前有時帶疑問詞what, when, where, which, why, how等。
如：He’s asking Yang Ling how to get there. 他正在問楊玲怎樣到達那裡。
總而言之，一定要記住：to後面用動詞原形。
