Answer 1

第一题：Einstein almost knocked me down（）he saw the man.
B:before 翻译成：爱因斯坦差一点把我撞倒（在看到我之前）。A直到C在。。。期间D当。。。时

第二题：My money（）. I must go to the bank to draw some of my savings out before I have none in hand。翻译为：我的钱快花光了，我必须在此之前去银行取一些出来。
A:has run out 已花完 B:is running out 正要花完 C:has been run out 已被花完 D:is being run out正在被花完。run out是不及物动词短语没被动。
第三题：carry on a conversation 短语搭配：执行，进行对话。
第四 题：remained silent 固定搭配：保持沉默，系表结构= keep silent
第五题：A:（）yesterdy？
B:Yes,as you saw,the party went on in a most pleasant atmosphere.
A:Had you a good time 应为did you have a good time
B:Did you have good time 缺a C:Did you enjoy your 应为yourself D:Did you enjoy yourself
