各位亲爱的听众朋友，欢迎来到点滴英语天天学的《每日原味美语》课堂！Juliet将带您体验美国哈弗大学纽约大学的口语课堂的学习内容。

今天，我们将学习这一课对话的文法。首先，我们还是来听听这段对话:

Jack: Hey! That girl is checking you out! Why don't you go say hello?

Tim: The last time I said hello to a girl in a place like this, she thought I was coming on to her and blew me off before I even had a chance to introduce myself.

Jack : That doesn't surprise me. Usually you strike out after one of using one your stupid pick-up lines!

Tim: I didn't go that far that time. Usually she was just playing hard to get.

Jack: Oh, no. There's Bonnie Margolin. A year ago, some mutual friends of ours fixed us up because they thought we would hit it off. Unfortunately, she was on the rebound, so I didn't want to get involved. I tried to let her down easy but she got furious ans started screaming at me. Oh, no! She's coming this way. Run!

我们来看下面的句子：

1. The last time I said hello to a girl like this...

解析：这句话中含有一个由时间副词when引导的定语从句。先行词是time，像表示时间的词语time, date, day等做先行词，引导词用when，且when可以省略。例如：

I'll never forget the time (when ) we first meet. （我永远也不会忘记我们第一次相遇的时间。）

The date ( when ) he joined the army was August 15th. ( 8月15日是我参军的日子。)

2. Usually you struck out after using one of your stupid pick-up lines.

解析：after是介词，后面接名词，如果后面是动词，就要使用动名词形式，句中的using one of your stupid pick-up lines就是动名词短语。 例如：

After winning the prize, she became famous overnight. （她获奖后，一夜之间就成名了。）

3. She thought I was coming on to her and blew me off before I even had a chance to introduce myself.

解析：这个句子是含有宾语从句的复合句。主句是：she thought，宾语从句是：I was coming on to her and blew me off before I even had a chance to introduce myself。在这个宾语从句中有含有一个由表示的时间的连词before引导的时间状语从句： before I even had a chance to introduce myself。

4. A year ago, some mutual friends of ours fixed us up because they thought we would hit it off.

解析：这是一个含有由表示时间的连词before引导的原因状语从句的复合句。主句是：some mutual friends of ours fixed us up，从句是because they thought we would hit it off。在从句中，又含有一个宾语从句：we would hit it off。

5. I tried to let her down easy but she got furious ans started screaming at me.

解析：这是一个并列句，由连词but连接，表示转折。例如：

I had asked every one but only two came. （我每个人都请了，但是只来了2个人。）

6. There's Bonnie Margolin.

解析：这是倒装句。这个倒装结构是：There+be+somebody or something。这样的倒装结构往往含有强调的意味。例如：

Here is the letter you have been looking forward to. （你企盼已久的信在这儿。）

我们今天的文法学习就到此结束。See you tomorrow!
