分析语态就是在确定逻辑主语之后,分析非谓语动词和逻辑主语在搭配使用时是主动还是被动关系。
1. ______from space , the earth looks blue .
2. ______Sunday I shall have a quiet day at home .
分析:句1. 表示“没有公共汽车”,应用“there be”结构,即逻辑主语是“there”,故选A 。
句2. 同理选D。
确定要选非谓语动词之后,第二步要分析其逻辑主语。非谓语动词虽不能作谓语,但仍具有动词特点,其逻辑上的动作执行者就叫做逻辑主语。非谓语动词作状语时,其逻辑主语须和句子的真正主语一致。若不一致,则须加上自己的逻辑主语。
1. ________no buses, we have to walk home.
A. There being B. It were C. There were D. It being
5. ________to the left , and you'll find the post office .
A. Turning B. To turn C. Turn D. Turned
分析:句1. 用连词but 引导并列句子,因此,前面也是个独立句子成分,故选C。
句2. 句中用逗号隔开,且无连词引导,因此,前面不是句子结构,只是句子的一个成分,故选A,用非谓语动词作状语。
句3. 同句2,选A 。
句4. 前面用if 引导从句,故选C ,构成从句谓语。
句5. 同句1,选C。
4. If you ________to the left, you'll find the post office.
3. ________to the left, you'll find the post office.
2. ________many times, he still couldn't understand it.
A. Having been told B. Told
C. He was told D. Though he had been told
1. ________many times , but he still couldn't understand it .
