授课讲义

I’ll certainly be more careful. 我以后一定会多加注意。这里面助动词是will,应该放在前面。It takes a long time. take用于花费时间。 It takes sb. sometime to do sth 做某事需要花费某人多长时间 It took me a week to finish this work. 我完成这项工作花了一周的时间。 We might not go anywhere. 我们可能哪也不去,而不是我们不可能去那。We can’t go anywhere。 In the end adv.最后。等于at last adv.最后=at the end of sth 在…结尾。

Expressions 1. must和have to的用法 | 两者都表示必要性,两者的主要区别在于: 1. must表示主观意愿,而have to表示客观事实。 2. must 只用于现在时,而过去时用had to,将来时用will have to。 3. must 不用于否定句,否定句用needn’t 不必要或don’t need to。mustn’t的意思 是不允许,禁止。 2. 情态动词表示推测: 情态动词表示推测的有:must一定、could很有可能、may可能、might有一些可能。 它们的用法是: 1. 它们表示推测只能用于肯定句之中,而疑问句用can,否定句用can’t不可能。 Can the he stay at home at the moment 现在他能在家么 He must be staying at home. 他一定在家。 He can’t be staying at home. 他不可能在家。 2. 情态动词用原形,表示对现在或将来的情况时行推测。 He must be a teacher. 他可能是一名老师。(系表) We may travel by sea next month. 下个月,我们可能乘船旅行。 3. 情态动词用be doing,表示对现在的情况进行推测。 He must be having a lot of money. 他一定有很多钱。 Jim may be playing the basketball. 吉姆可能正在打篮球。 4. 情态动词用have done,表示对过去的情况进行推测。 It must have rained yesterday. 昨天一定下雨了。 I can’t have been late yesterday. 我昨天不可能迟到。 She could have phoned you last night. 她昨晚应该给你打电话了。 He must have stayed at home when we arrived. 当我们到达的时候,他一定在 家。 5. 情态动词用have been doing,表示对过去正在进行的动作或过去一直进行的动 作进行推测。 She may have been doing his homework last night. 昨天晚上,他可能一直在写作 业。
