题目内容
16.You'd better not ride the bicycle on snowy days; you ______ fall.( )A. | must | B. | might | C. | have to | D. | ought to |
分析 你最好不要在下雪天骑车,你可能会跌倒的.
解答 答案:B.
Might表示"可能",must"必须",have to"不得不",ought to应该,had better do sth最好做某事,是建议别人做某事,所以选B.
点评 对于Might,must,have to,ought to这几个情态动词要分清他们发生的可能性;结合句子的意思及语境来进行恰当的选择.
must必须,是一种主观上的决定,可能性最大,have to意为不得不,是客观上的一种要求,别无选择,含有被迫之意,可能性比must小;ought to应该,等同于should,主观上的意愿,可能性较小;might可能,语气最委婉的一个情态动词,可能性最小.
He said she must go with me.他说她必须同我一起去.
We had to borrow a lot of money.我们不得不要借一大笔钱.
