23、放在句首。在强调句型中一般只能用 until，不用 till。It was not until she took off her dark glasses that I recognized her.第 页 共 7 页4直到她摘下墨镜，我才认出她。3. 状语从句可放在主句之前或之后，放在主句之前时一般用逗号与主句分开。有时可置于主句中间，前后用逗号。bwhen 更强调特定时间，还可表示从句中的动作先于或后于主句的动作。When I had given Mary the spare ticket, I found my own already gone.当我把多余的票给了玛丽时，我才发现我自己的

25、should go where we are needed most.我们应该到最需要我们的地方去。5. 有些时间、地点、条件、方式或让步等状语从句中，如果谓语含有动词 be，主语又和主句中的主语一致，或者主语是 it，常把从句中的主语和谓语的一部分（特别是动词 be）省略掉。Look out for cars when crossing the street.过街时当心车辆。(= when you are crossing the street)She hurriedly left the room as though angry.她急匆匆地走出屋去，好象很生气的样子。(= as thoug
