7、I had to do something. 我必须做点什么!

辨析：have to 与must

(1)must多表示主观需要或责任感的驱使有必要或有义务去做某事，多译为“必须”，而have to多表示客观存在的环境所限,即客观要求(无奈)而为之，多译为“不得不干某事”。

Eg：I must clean the room because there are too dirty.(无人强迫) 因为太脏了，我必须要打扫房间。

We must be there on time. (责任感的驱使)我们一定准时到达。

I have to do my homework now.(不得不做) 我现在不得不做作业。

I have to leave school because my family is poor now.(无奈) 因为家里穷了，我不得不退学。

(2)must没有时态的变化，而have to有时态的变化。

Eg: Daming was hurt. The doctor said he had to stay in hospital for about two weeks. His

father has to go to take care of him.

We don’t have to go to school on Sundays. 星期天我们不必上学。

(3)must的否定为mustnt， 多表示“禁令”。

Eg：No!You mustnt turn left! You must turn right into The Strand. 不!你不能向左转!你应该向右转进入到strand中。

由must引起的疑问句，肯定回答要用must或have to，否定回答要用needn’t或don’t have to，意思是“不必”; 此用法在中考中的单选题中容易出现!

Eg: 1)—Must I finish my homework before eight o’clock? 我必须要在8点之前完成作业吗?

—Yes, you must. 是的，必须。

【拓展】

1)try one’s best to do sth. 意为“尽某人最大努力做某事”
