是在昨天电视上播放了这条新闻。

2. And this is the first time I've visited your hometown.

这是我第一次到你的家乡来参观。

This/It is the first/second.../last time＋that­clause."这是某人第一/二....../最后一次做某事"，that引导定语从句，在口语中that常省略。

(1)当主句用一般现在时时，that从句中的谓语用现在完成时；

(2)当主句用一般过去时时，that从句中的谓语用过去完成时。

①It's_the_second_time_that John has_held an art exhibition.这是约翰第二次举办画展了。

②It_was_the_third_time_that she had_come to this mountain village to see the children.

这是她第三次来到这个山村看望这些孩子了。

表示"是(某人)做某事的时候了"的句型有：

It is time for sth

It is time (for sb)to do sth

当堂检测：

(1)翻译句子

　　　①It was 10 years since they had lived there.

　　　②How long is it since you were in Shanghai?

(1)用所给动词的适当形式填空

　　　①This was the first time she (leave) her motherland.

　　　②It is the second time (that) I (read) the book.

　　　③It is high time that we (do) something to stop it happening again.

课后反思：
