Lesson 127 A famous actress著名的女演员

课文详注 Further notes on the text

1.I thought so.我也这样想。

so 是代词,意为“这样”、“如此”。 I think so的否定式为I don't think so(我不这样认为)。类似用so的短句如:

I hope so. 我希望如此。

I expect so. 我期待如此。

I told you so. 我这么告诉过你的。

2.have another look,再(仔细)看一眼。

3. look old,看上去老。这里look是系动词,后跟表语。

4.at least,至少。

5.I'm sure she is.我肯定她有40岁了。 其后省略了 at least forty。

6.not more than twenty-nine myself,我自己还没29岁。

其中not more than是“不超过”、“不到”的意思。这里反身代词myself是I的同位语,用来加强语气。

She did it herself. 这事是她自己做的。

1. Must be:

2. Can't be:

在使用 "must" 和 "can't" 进行猜测和推断时,需要注意的是,这种用法并不提供绝对的确定性,而是基于当前可用的信息做出的最合理的假设。因此,这种推断可能会随着新信息的出现而改变。


"mustn't" 是英语中的一个情态动词,用于表达禁止或不允许做某事。它是 "must not" 的缩写形式,通常用于正式和非正式的语境中。以下是关于 "mustn't" 的一些用法介绍:

1. 表达禁止:

"mustn't" 最常见的用法是表达某事是被禁止的。例如:

You mustn't touch the hot stove. (你不能触摸热炉子。)

这里 "mustn't" 用来告诉某人某事是绝对不可以做的,做了可能会有危险或后果。

2. 法律或规则禁止:

当某事违反法律或规则时,也可以使用 "mustn't"。例如:

You mustn't park here; it's a no parking zone. (你不能在这里停车;这里是禁止停车区。)

在这个例子中,"mustn't" 用来指出违反规则的行为。

3. 道德或社会规范:

"mustn't" 也可以用来表达道德或社会规范所不允许的行为。例如:

You mustn't lie to your friends. (你不应该对朋友撒谎。)

这里 "mustn't" 用来强调诚实作为一种社会期望和道德规范。

4. 给出建议或警告:

当给出建议或警告以避免某些可能导致不良后果的行为时,也可以使用 "mustn't"。例如:

You mustn't go out in this storm; it's very dangerous. (你不应该在这场暴风雨中出去;这非常危险。)

在这个例子中,"mustn't" 用来警告某人不要做某事,以避免可能的危险。

5. 表达强烈的不允许:

当需要表达强烈的不允许或禁止时,"mustn't" 比 "don't have to" 或 "needn't" 等表达方式更加强烈。例如:

You mustn't tell anyone about this secret. (你绝对不能告诉任何人这个秘密。)

这里 "mustn't" 用来强调保守秘密的重要性。

在使用 "mustn't" 时,需要注意的是,它表达的是一种强烈的禁止或不允许,通常用于指导行为和预防不良后果。同时,"mustn't" 也可以用来表达一种责任感或义务感,即某人有责任不做某事。
