### 第1段

'At the time the murder was committed, I was travelling on the 8 o'clock train to London,' said the man. 'Do you always catch such an early train?' asked the inspector. 'Of course I do,' answered the man. 'I must be at work at 10 o'clock. My employer will confirm that I was there on time.' 'Would a later train get you to work on time?' asked the inspector. 'I suppose it would, but I never catch a later train.' 'At what time did you arrive at the station?' 'At ten to eight. I bought a paper and waited for the train.' 'And you didn't notice anything unusual?' 'Of course not.' 'I suggest,' said the inspector, 'that you are not telling the truth. I suggest that you did not catch the 8 o'clock train, but that you caught the 8.25 which would still get you to work on time. You see, on the morning of the murder, the 8 o'clock train did not run at all. It broke down at Ferngreen station and was taken off the line.'

中文理解：“在凶杀发生的时候，我正坐在8点钟开往伦敦的火车上。” 那人说。 \[2]“您总是赶这样早的火车？”探员问。 \[3]“当然是的，”那人回答。“我必须在10点钟上班，我的雇主可以证明我是按时到了那儿的。” \[4]“晚一班的车也能按时送您上班吗？” \[5]“可能也可以吧，但我从来没坐过晚一班的车。” \[6]“您几点钟到的火车站？” \[7]“7点50分。 我买了张报纸，等着车来。” \[8]“您没有注意到发生了什么异常情况吗？” \[9]“当然没有。” \[10]“我认为，”探员说，“你没说实话。我认为你乘的不是8点钟的火车，而是8点25分的，这班车同样足以让你准时上班。你看，在凶杀发生的那天早晨，8点钟的那班车根本没有发车。那班车在芬格林车站出了故障，已经停运了。”

* **on time**：高速 / 绕圈 / 准时 / 说真话；按原句识别是在说明方式、时间还是话语是否真实。

#### 1. the murder was committed, I was travelling…

复合句，主句主谓结构，时间状语从句为主谓结构，后面to London 为介词短语作后置定语修饰train. 标题的alibi 要留意发音，最后的i 是/ai/的音，该词除了不在犯罪现场证明，还有借口、托词之意.

#### 2. Do you catch a train?

疑问句，主谓宾结构.

#### 3. of course I do.

简单句，主谓结构，本句是回答上一句do you 开头的疑问句，of course 在这里作副词，表强调，当然之意，你也可以替换为yes.

#### 5. My employer will confirm that I was there.

复合句，主谓 + 宾语从句结构，从句为主系表结构.

#### 6. Would a train get you to work?

疑问句，主谓宾 + 宾补结构.

#### 7. I suppose it would, but I catch a train.

并列复合句，but 前句为主谓 + 省略了that 的宾语从句，该从句为主谓结构；but 后为主谓宾结构.

#### 8. did you arrive?

疑问句，就时间进行提问，所以回答是具体的时间即可.

#### 10. I bought a paper and waited…

并列句，and 连接的两句，前句为主谓宾结构，后面为省略了主语的主谓结构.

#### 11. you didn't notice anything…

简单句，主谓宾结构，其实是可以把didn’t 提前的，改为Didn’t you notice anything unusual?

#### 12. I did not.

省略句，did you…?的否定回答是no, I did not，这里省略了主语和谓语，只留下了否定词not.

#### 13. I suggest that you are not telling the truth.

复合句，主句主谓 + that 引导的宾语从句结构，从句为主谓宾结构. suggest 这里不是提醒，对话内容已经开始给犯罪嫌疑人进行犯罪时间推理了，没什么好提醒的， 而是认为. 从本句开始，译文的您也改为你，表示犯罪嫌疑人露出了马脚.

#### 14. I suggest that you did not catch the 8 o'clock train, but that you caught the 8.25 which would get you to work…

复合句，主谓主句主谓 + 宾语从句，该从句为but 连接的并列句.

在宾语从句中，前句为主谓宾结构，后句还额外有一个which 引导的定语从句，后句本身是主谓宾结构，该定语从句是主谓宾 + 宾补结构.

#### 15. the 8 o'clock train did not run…

简单句，主谓结构.

#### 16. It broke down and was taken off the line.

并列句，and 连接前后两句，主语it 指八点的那个列车，and 前句为主谓结构，动词短语break down 作谓语.

and 后面的 was taken off the line 是被动结构，意为这班故障列车被撤出线路、停止运营。off the line 是介词短语，the line 不是 was taken 的直接宾语；这不等于整条铁路线路被取消。
