Lesson 34 Quick work 破案 “神速”

1. Dan Robinson has been worried all week.
Dan Robinson焦虑了整整一个星期。
这个句子是be worried句型的完成时，大家别误认为是被动语态了。这种动词过去分词作为形容词使用，来表示有关人的情感方面。其它的比如：
We were amused by his funny stories.我们都被他的滑稽故事逗乐了。
I’m pleased with what you’ve done.我对你所做的感到满意。
We were surprised at the news.我们对这消息很吃惊。

2. Last Tuesday he received a letter from the local police. In the letter he was asked to call at the station.

The local police是指“当地警察局”。
Local可以表示“地方性的”或是“当地的”、“本地的”。比如：
A local newspaper 地方性报纸
Local news 本地新闻

与call有关的短语：
（1） call at (= visit ) 表示“到…去，拜访”，后跟某个地点场所：
He was asked to call at the station.

（2） call on (=pay a visit) 表示“拜访，访问”，后接某个人：
I called on George yesterday.

比较：We should call at Bob’s while we’re in London.
We should call on Bob while we’re in London.

（3） call out to (=shout / cry to ) 大声喊
Some people on the bank called out to the man in the boat, but he did not hear them. ( lesson 30)

（4） call up (=telephone) 给...打电话
She’ll call you up tomorrow.

（5） call off (=cancel ) 取消
The party has been called off.

比较 Put Off 和 Call Off

put off 指推迟，而call off主要指取消某个安排、活动或事件, 如：
It was so cold that we had to put off the match. 天气太冷，我们不得不推迟了比赛。
It was so cold that we had to call off the match. 天气太冷，我们不得不取消了比赛。

3. Dan wondered why he was wanted by the police, but he went to the station yesterday and now he is not worried anymore.

wonder这个词表示推断时，后面只能跟由疑问词引导的宾语从句，即“wonder whether/if/who/when/where/what/why + 从句”

She wondered what the child was doing.
I wonder whether/if he will come.

*宾语从句需注意语序, 虽然从句表述的实质上是个问题，但从句的语序仍是陈述句的语序。
wanted by the police 是一个双关语，在一般情况下，它解释为“受到警方通缉”，如：a wanted man (一名通缉犯)，但在这篇文章里，该短语应作“警察要他去”之解。

not…anymore 相当于 not…any longer, 只是后者比较正式。

4. At the station, he was told by a smiling policeman that his bicycle had been found.

现在分词smiling 作policeman的定语，请作用相当于形容词。我们还可以说：
a sleeping dog 一只睡着的狗
a worried face 一张焦虑的脸

5. Five days ago, the policeman told him, the bicycle was picked up in a small village four hundred miles away.

首先，句中的the policeman told him由于前后都是逗号隔开，所以是个插入语。所以主句是：Five days ago the bicycle was picked up in a small village four hundred miles away.因此，我们应理解为：车子是五天前找到的。而不能理解为：警察是5天前告诉他这个消息的。

pick up 在这句话中解释为：拾到。
在不同的上下文中pick up也可以解释为：
a) 拿起：
I picked up the receiver as soon as the phone rang. 电话铃一响，我就拿起了话筒。
b) 用车接人：
I’ll pick you up at your office. 我来办公室接你。
c) （无意地，顺便地）买到：
Where did you pick up that book? 你在哪儿买到那本书的？
d) (不经正规上课) 学到：
She picked up French in Paris. 她是在巴黎学会法语的。

6. It is now being sent to his home by train.

is being sent是is sent的现在进行时结构。是被动语态用于现在进行时，其结构为“am/is/are+being+动词过去分词”。

7. Dan was most surprised when he heard the news.

Most前面不加冠词，表示“非常”、“极其”，用来修饰形容词或副词：
That’s most kind of you . 你心肠真好。
He was most polite to me. 他对我真是彬彬有礼。

8. He was amused too, because he never expected the bicycle to be found.

to be found是动词不定式的被动语态，在这里作宾语补足语。
我们说“希望某人做某事”是expect sb. to do sth.。

9. It was stolen twenty years ago when Dan was a boy of fifteen.

when Dan was a boy of fifteen是定语从句，修饰twenty years ago。
