A perfect alibi：新概念英语第二册自学导读笔记第87课新概念英语第二册第87课课文课文重难点详解 Further notes onthe text1．A perfect alibi，（标题）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：Ian had an alibi/alibis for that morning.伊恩有那天上午不在场的证据/证明。
与它搭配的动词通常有offer，prove，set up等。
2．…I was there on time.……我是按时到了那儿的。
on time为固定短语，表示“准时”、“按时”（注意它与in time的区别）：Can you arrive on time?你能准时到吗？Tom is never on time. He always keeps other people waiting.汤姆从来不准时。
他总是让别人等。
3．And you didn't notice anything unusual? 您没有注意到有什么异常情况发生吗？这是一个陈述疑问句，即它具备与陈述句同样的基本语法结构，但用升调提问。
这种句子在英语中不常用：不定代词如anything，something等被形容词修饰时，形容词必须跟在不定代词之后：This is something special.这很特别。
This isn't anything important.这并不重要。
I'd like something cheaper.我想买点较为便宜的东西。
4．I suggest…that you are not telling the truth. 我提醒您……您讲的不是实话。
I suggest（that）…在这里用于提出质疑，译为“依我看……”、“恐怕……”：I suggest that he is not so honest as he looks.依我看他并不像他看上去那么诚实。

The inspector asked at what time he had arrived at the station. The man said that he had arrived at the station at ten to eight. He added that he had bought a paper and waited for the train. When the inspector asked him if he had noticed anything unusual, the man said he hadn't.

The inspector pointed out that on the morning of the murder, the eight o'clock train did not run at all, as it had broken down at Ferngreen station and had been taken off the line.2．多项选择题答案1. c根据课文第5行和第14行，可以判断只有c. he arrived at work on time 是极好的不在犯罪现场的理由，其他3个虽然都是课文所涉及到的情况，但都不是充分的不在犯罪现场的证据。
