在语法填空和短文改错中it+be+时间+从句是一个常考的句式，可是学生常常会因为判断失误而选错从句的关联词。其实只要细心这一句式还是有规律可循的。

1. It was / will be +时间段+before...表示“过多长时间才......\在否定句中，表示”没过多长时间就......“。如：

It will be two years before we get married. 我们要过两年才结婚。 It was not long before he left. 不久之后他就走了。

2. It is / has been +时间段 +since... 表示”自从......以来有......时间了\此时从句时态常用一般过去时。

It is just a month since I moved here. 我搬到这儿刚好一个月。

It has been ten years since we lived here. 我们没住这儿已经十年了。 3. It was / will be + 时间点+ when...

It was seven o'clock when I got to school this morning. 我是早上七点到学校的。 4. It is / was +时间状语 +that... 这是强调句型的考查

It was at six o'clock this morning that they set out. 他们是在今天早上六点动身的。 5. It is / was + not until... + that ... 这个句式考查的也是强调句型

It was not until he took off his sunglasses that I recognised that he was a famous film star. 直到他摘下眼镜我才认出他是一个著名的影星。

6. It is + time +that... 这个句型表示的是”该是做......的时候了 ”。that从句中的谓语动词多用一般过去时或者should +动词原形

It's time that I went to pick up my daughter. 我该去接我女儿了。

总结：只要学生能注意到各个句式之间的细微差别比如：时态，时间点、时间段或从句的时态等，那么许多填空和改错都会迎刃而解。同时如果能把这些句式熟练运用到作文中去，
