【12字箴言：谓非谓，找主语，析语态，定时态】
【妙语解析】
一、谓非谓：判定句子中是否用非谓语形式。方法：一个句子中只能有一个位于动词，分析句子结构，若出现两个动词，必有一个要采取非谓语的形式。
1._____many times , but the student still couldn't make it ，which made the teacher angry.
2. _____many times , the student still couldn't make it ，which made the teacher angry.
A. Having been taught B. Taught C. He was taught D. Although he had been taught
分析：
1. 此为两个并列句，用转折连词but 连接，缺少的是谓语动词，所以不采取非谓语的形式。
2. 句中用逗号隔开,且无连词引导，因此，前面不是完整的句式结构，只是句子的一个成分，故选A，用非谓语动词作状语。被教了很多次，这个学生仍然不会做，这让老师很生气。
即有逗号，无连词，则选用非谓语的形式。
Exercises：
1. ______to the right , you'll find the bus station .
2。 ______to the right , and then you'll find the bus station .
A.Turning B. Turn C. To turn D. Turned
Key：AB
二、找主语：找非谓语动词的逻辑主语。方法：非谓语动词在功能上虽不能作谓语，但仍具有动词的特点，其逻辑意义上动作的发出者就叫做逻辑主语。
1. ____ to the market, these products sell good.
A. Introducing B. Introduced C. Introduce D.Being introduced
分析:
由句意可知，首次面市的这些产品销量很好。被推向市场的是这些产品 these products,这就是非谓语部分的逻辑主语， 与句子的主语一致, 故选B
Exercises：
1._______no more traffic , we had to wait to be picked up home by Tom.
2.______Saturday, I can have two days off to go shopping.
A. There being B. It were C. There were D. It being
Key：AD
