两种特殊情况下的强调结构
（要点精讲）
一、until的强调句结构
对句型强调时，要把not连同until短语或从句一起提前，写成It is/was not until … that…。如：
I didn’t realize that I had left my umbrella until I got home.
→It was not until I got home that I realized that I had left my umbrella.
直到我到家的时候，我才意识到我落了伞。
He did not start to study French until he was fifty.
苏有朋个人资料简介→It was not until he was fifty that he started to study French.
直到他五十岁了，他才开始学习法语。
He didn’t notice me until I spoke to him.
→It was not until I spoke to him that he noticed me.
直到我跟他说话他才注意到我。
二、强调句子谓语动词时，可以将助动词do(does，did)置于动词原形之前，来加强谓语动词的语气。如：
Who broke the window? 谁打碎了玻璃？
→Who did break the window? 究竟是谁打碎了玻璃？
Be careful! 小心！
→Do be careful！ 千万要小心！
He enjoy drawing. 他喜欢画画。
→He does enjoy drawing. 他的确喜欢画画。
Be kind to your children! 请善待你的孩子!
→Do be吃马蹄的禁忌 kind to your children! 请务必善待你的孩子！
