高三全科輔導(dǎo)

　　1. 句型為：It is/ was not until 被強(qiáng)調(diào)部分 that 其他部分

　　e.g. 普通句：He didn't go to bed until/ till his wife came back.

　　強(qiáng)調(diào)句：It was not until his wife came back that he went to bed.

　　2. 注意：此句型只用until，不用till.但如果不是強(qiáng)調(diào)句型，till， until可通用;因?yàn)榫湫椭蠭t is/ was not …… 已經(jīng)是否定句了，that后面的從句要用肯定句，切勿再用否定句了。
