動詞不定式：
動詞不定式是一種非謂語動詞形式，其結構為“to+動詞原形”，沒有人稱和數的變化。它和其后面的名詞等構成不定式短語，在句子中可以用作主語、表語、賓語、補足語、定語、狀語等。例如：To be a doctor is hard.（作主語）；It is hard to be a doctor.（it作形式主語，真正的主語是to be a doctor）；I want to go to school.（作賓語）。
動詞不定式的用法
動詞不定式作賓語, 如：want to do sth / try to do sth / hope to do sth / decide to do sth / refuse to do sth / need to do sth / agree to do sth /
plan to do sth
動詞不定式作賓補 ( v. + sb. (not ) to do sth ) 如：tell sb. (not ) to do sth / invite sb. (not ) to do sth / want sb. (not ) to do sth / would like sb. (not ) to do sth / teach sb. (not ) to do sth / ask sb. (not ) to do sth

語法知識
本話題重點是if引導的條件狀語從句，時態遵循“主將從現，主祈從現，主情從現”的原則。即如果主句是一般將來時、祈使句或含有情態動詞，從句要用一般現在時表示將來。例如：If it rains tomorrow, we will stay at home.（如果明天下雨，我們就待在家里。）同時要注意區分if引導的條件狀語從句和賓語從句，if在賓語從句中譯為“是否”，可與whether互換，但句末有or not時只能用whether。
