3.根據主從句的關系來確定時態. 4.根據語言習慣來確定時態
*1.come,go,leave 等趨向性動詞的進行時可用來表示即將發生的動作.
*2.永恒的真理和客觀存在的狀態用一般現在時.
*3.祈使句中,或在情態動詞,助動詞后,謂語動詞用原形

3.在 keep,enjoy,finish,mind 等動詞后采用動詞的--ing 形式.
4.在動詞 decide,hope,wish,hate 等動詞后應用動詞不定式作賓語,而在ask, tell,want,teach 之后則用動詞不定式的復合結構,即 “ask sb. to do sth.”的形式
5.在see,hear,watch,make,let等后面作賓語補足語的動詞不定式應省略動詞不定式符號“ to”, 但在被動句中, 應添上"to".
6.在 It‘s time(for sb.)to do sth. It’s kind/nice/good of sb. to do sth.
It takes sb. some time to do sth. 的句型中, 動詞不定式短語作句子真正的主語.
