 | 2 : Now I have a good salary, I __________ worry about paying the rent. |  |
 |
 | The possible answers were: mustn't have to don't have to must to not You said: mustn't have to don't have to must to not |  |  |
 | | 对不起,这不是正确答案。Must 是必须的意思,有一种强制性,不做不行。但这个句子的语气并没有这么强烈,仅仅是说没有必要担心。所以你需要另外一个情态动词。 恭喜你,答对了!这句话是说,我没有必要担心交房租了。 对不起,这不是正确答案。 Must to not 语法上不正确。 对不起,这不是正确答案。Have to 是说有必要担心。显然和这个句子想表达的意思相反。 你没有回答这个问题。 |  |

I could call my mum because it's her birthday. You said: I have to call my mum because it's her birthday. I ought to call my mum because it's her birthday. I should call my mum because it's her birthday. I could call my mum because it's her birthday. |  |  |
 | | 恭喜你,答对了! Have to 表示有一种责任性或强制性做某事。如果不做那件事,可能会有后果产生。 对不起,这不是正确答案。尽管ought to 有时语气也很强烈,但是这里没有have to 强烈,并且这种责任感更多由外部原因引起。 对不起,这不是正确答案。Should 表示一种比较弱的责任性。 对不起,这不是正确答案。Could 不表示责任性。它只表示一种可能性。 你没有回答这个问题。 |  |

 | | 恭喜你,答对了! Can't 在这句话中是指有规定或者法律限制人们做某些事情。 对不起,这不是正确答案。Shouldn't 这个情态动词的强制性和责任性不够强,不能表达出对违反规定或法律的限制。 对不起,这不是正确答案。Don't have to 意思是说没有必要。显然有些辞不达意。你需要使用另外一个情态动词。 对不起,这不是正确答案。Oughtn't to 这个情态动词的强制性和责任性不够强,不能表达出对违反规定或法律的限制。 你没有回答这个问题。 |  |
