第八十七课 A perfect alibi 极好的不在犯罪现场的证据

1.A perfect alibi 极好的不在犯罪现场的证据
alibi为法律用语，含义是“不在场证明”、“当时不在场的申辩”，是可数名词：
He has an alibi/alibis for that night.他有那天晚上不在场的证据。

2.At the time the murder was committed, I was travelling on the 8 o'clock train to London.
(1)at the time意为at the moment when something happened。
(2)the murder was committed可以看作是定语从句修饰time, 而如果前面的词如果是the time, the moment, the way等做先行词的时候，后面的关系副词是可以省略掉的。
commit vt.
犯（罪），做（错事、坏事等）；
A murder was committed at 8 o'clock this morning.
今天早上8点钟发生了一起凶杀案。
另外给大家两个短语：
commit a murder 犯谋杀罪 commit suicide 自杀

3.catch a train 乘火车，相同的用法还有 catch a bus
If we come here 10 minutes earlier will catch the train(bus).
如果我们能早到10分钟我们就能赶上火车(汽车).
顺便给大家说一下catch you later这个短语，意思是再见的意思！

4.My employer will confirm that I was there on time.
我的雇主会证明我是按时到了那儿的
(1)employer 雇主 employee 被雇的人
类似的还有interviewer面试的人 interviewee被面试的人
(2)confirm vt.
证实，确定：
His predict is confirmed.他的预言得到了证实。
巩固，加强：
What he saw and heard that night confirmed his belief that he will succeed.
那天晚上的所见所闻使他更加坚信他会成功.
(3)on time为固定短语，表示“准时”、“按时”（注意它与in time的区别)按时
This teacher is never on time for class and students have to wait for him each time.
这位老师从来不准时，每次总是让学生等。
The girl will die unless the doctor comes in time.
如果医生不及时赶到，这个女孩就有可能死。

5.And you didn't notice anything unusual?
难道你没有注意到有什么异常情况？
这是由陈述句后加问号表示的问句。

6.you are not telling the truth.你没有说实话。
如果说实话实说，我们可以用to call a spade a spade.
Let's call a spade a spade.
让我们实话实说吧！

7.I suggest that you did not catch the 8 o'clock train, but...
suggest 提醒，暗示：
It suggested that you didn't do well in your final exam.
这表明你的期末考试考的并不好。
suggest 建议，注意用虚拟语气：
I suggest that he go to the hospital to have a body examination.
我建议他去医院进行一次体检。

8.It broke down at Ferngreen station and was taken off the line
(1)break down 抛锚，出故障
The car broke down in the middle of the trip.
汽车在旅途中途抛锚了.
(2)be taken off the line 取消航线
