Kitty plans to take Linda out. Linda wanted to visit the park. Sandy agrees to go with them. Millie decided to stay at home.,Please go on to look at the sentences below. Pay attention to the colored words.,上面例子中主要行為動詞后面的動詞 都采用了“to + 動詞原形”的結(jié)構(gòu)，我 們把這種結(jié)構(gòu)稱為動詞不定式（有時 可以不帶to）。動詞不定式?jīng)]有人稱 和數(shù)的變化，在句子中不能單獨作謂 語，其否定形式是“not to + 動詞原形”。,什么是動詞不定式(to-infinitives)？,We often use to-infinitives after these verbs.,agree choose decide hope learn plan prepare want like start begin fail wish try remember forget,1. 當(dāng)我們猜測某件事發(fā)生的可能性時，常 用may來表示“也許”、“可能”。 2. 當(dāng)句子中已經(jīng)有謂語動詞，而我們又要 表達不止一個動作概念時，其余的動詞 可以使用非謂語形式表達。動詞不定式 就是動詞的一種非謂語形式，其肯定形 式是“to + 動詞原形”，其否定形式是 “not to + 動詞原形”。無人稱、數(shù)和時 態(tài)的變化。,Reflection,Millie is in the zoo.
