1.D。It/ This/ That + be + the first (second?) time + that从句。该句型中that从句要求用完成时态。have been to“已经去过（某地，现在人已经不在哪儿）”。Have gone to“已经出发到（某地，尚在途中或刚到达）”。 在这一句型中，如果句中的be动词为一般现在时is，that从句中的谓语动词用现在完成时have(has) done sth.。如果主句中的be动词为一般过去时was，that从句中的谓语动词用过去完成时had done sth.,意为“这（那）是某人第几次做某事了”。例如：It is the second time that he has been in Japan.“这是他第二次去日本”。He told us it was the third time that he had visited the Great Wall of China.“他告诉我们那是他第三次游长城”。 2. D。此题考查句型：It + be + 一段时间 + since从句。译文：“聚会如何?” “非常好。我已经好多年没有那么高兴了。”since从句中的enjoyed myself表示在过去曾经那么高兴过，但是没有那样高兴已经延续了多年”。

在这一句型中，主句中的be动词常用is或has been, since引导的从句中的谓语动词常用一般过去时。如果主句中的be动词为was, since从句中的谓语动词则用过去完成时。注意：从句中的谓语动词如果为短暂性动词，应为肯定意“某人做某事已经有多长时间了”；如果从句中的谓语动词为延续性动词，则为否定意“某人已经有多长时间没做某事了”。又如：It is/has been three years since he left his village.“他离开村子已经有五年了”。It was six year

s since she had lived in this city.“那时他不住在这个城市已有三年了”。有时考查该句型中的谓语动词。

3. C。此题考查句型：It + be + 一段时间 + since从句。详见第2小题。 4. A。此题考查强调句型: It + be + 被强调部分 + that + 陈述句。 5. D。本句为强调句型: It + be + 被强调部分 + that+ 陈述句。 选择时要注意两点：用疑问语序；特殊疑问词充当say 的宾语，必须使用代 词what, what又是被强调部分。句中be动词的时态形式只可用is或was。陈述句部分的谓语动词如果是一般现在时态或将来时态，be动词用is；如果是过去的某一种时态，be动词用was。这一结构可以对句中的主语、宾语或状语加以强调，但是不能对句子的谓语进行强调。强调人时可以用who/whom代替that。强调其它成分只能用that。（特别注意：强调时间或地点时，不可以用when, where连接，只能用that）。其意义可以视情况而定。 6. D。详见第1小题。

7. B。本句为主语从句: It + be + adj. + that-clause。

8. C。此题考查句型：It + be + 一段时间 + before从句。before“（?之后） 才?”。译文：“要过好几个星期校长才会回来”。

在这一句型中，如果陈述过去所发生的事情，主句中的be动词常用was/wasn’t , 从句中的谓语动词常用一般过去时态，构成“It + was/wasn’t + 一段时间 + before sb did sth.”，意为“过了（没过）多久某人就干某事了”。如果陈述将来要发生的事情，主句中的be动词用will/won’t be, 从句中的谓语动词用一般过去时态，构成“It + will/won’t be + 一段时间 + before sb does sth.”，意为“要（不要）过多久某人就（才）会干某事”。例如：It was years before he returned.“过了好多年他才回来”。It won’t be two hours before we finish the job.“要不了两个小时我们就会完成这项工作”。 9. B。详见第5小题。
