It引导的几个易混句型辨析
It引导的几个易混句型辨析20. John thinks it won’t be long he is ready for his new job.A. whenB. afterC. beforeD. since部分考生看到这个题还是有点迷糊，搞不清楚到底该填什么。
现就it引导的几个相似句型在这里加以分析，教大家怎么进行辨析才能很快得出正确选项。
（一）It is +一段时间+since从句这个句型要注意两点：第一，从时态上判断，通常since 前的时态为is 或has been, since 后的时态为一般过去式。
例如：It is (has been) ten years since my grandmother died. 我祖父去世有十年了。
第二，注意since 后面的动词，如果是短暂性动词，则表示动作开始有多久了；如果是延续性动词，则意思刚好相反，表示动作结束有多久了。
例如：（1）It is / has been three years since they got married. 他们结婚三年了（2）It is / has been three years since they were married. 他们离婚三年了如果since从句表示的是某种状态，并且持续到现在，偶尔也可以用完成时态。
例如：It's 3 days since I've been like this. 我像这样已经三天了。
（二）It will be / was +一段时间+before从句该句型主句中的it指时间，主句通常是一般将来时或过去时两种时态。
此句型的判断可以从句子翻译来看，从主句开始译为“过多久以后……才……”，从从句上译为“干……前还有多久/过了多久……”，如果从前面翻译和从后面翻译句子意思一样，就说明要填before。
例如：（1）It was two months before he found his lost boy. 两个月之后他才找到他的儿子。
