10.In the US, workers called them“blue Mondays”.(Page 73) 在美国，工人们把它们叫做“蓝色星期一”。
蓝色（blue）在汉语中的引申意义较少，而在英语中blue是一个含义十分丰富的颜色词。在翻译同这一颜色有关的表达时，我们应该注意其中的特别含义。 英语的blue常用来喻指人的“情绪低落”、“心情沮丧”、“忧愁若闷”，如： 1）They felt rather blue after the failure in the football game. 球赛踢输了，他们感到有些沮丧。
2）—She looks blue today.What’s the matter with her? —She’s in holiday blue.
—她今天显得闷闷不乐，出了什么事？ —她得了假期忧郁症。

12. Did you have a good time? (Page 76) 你们玩得高兴吗？
have a good time = enjoy oneself过得愉快；玩得高兴。类似的说法还有have a great time, have a nice time, have a wonderful time。
三.语法学习 I was doing some washing. I was doing some cleaning. (Page 69) 我在洗衣服。 我在打扫卫生。这句用的是过去进行时.
1. 过去进行时表示过去某一时刻正在进行或发生的动作,也表示过去一段时间内的活动或那个阶段正在进行的动作.如: He were watching TV at 8:00 last night. They were writing a book last month.
3. 过去进行时由be (was/were)+动词ing 形式构成的, 肯定句:主语+was/were +doing +…
否定句: 主语+wasn‘t/weren‘t +doing +… 一般疑问句: Was/Were+主语+doing+…
肯定回答:Yes, 主语+was/were. 否定回答:No, 主语+wasn‘t/weren‘t.
如: They were studying English at this tine yesterday. They weren‘t studying English at this time yesterday. Were they studying English at this time yesterday? Yes, they were. / No, they weren‘t.
