我会追加分数的

1.我第一次做也是选B,这种题目有点争议,不同老师会讲不同答案.如果硬要理解的话,我觉得2楼的说的不错,确实是强调一看见就打电话.
2.这题就是用having done表先后,V-ing好像没有表示条件的吧
3.When completed就是When（it is） completed ,being completed是现在进行时的被动语态,表示的是正在进行的被动的动作,从题意上显然不对
4.两个词组的区别：see sb.do sth.表示看到全过程,see sb.doing sth.表示看到的动作正在发生.如果这题选的是第一个词组那就要还原to,但是用第二个词组,就没有了.
5.B和D 虽然都是被动的,但是注意到speak是不及物动词,你经常会听到speak to sb.女孩不会主动说话,除非有人跟她讲话,她是词组里的sb.所以to不可省的.换个角度也许更好理解The shy girl never speaks unless (sb.speak to her) 把括号里的换成被动语态就是The shy girl never speaks unless(she is) spoken to.

时态填空,(see)the house on fire,he dialed 119. ____the house on fire,he dialed 119. ____the house on fire,he dialed 119.选seeing还是having seen They were surprised to see the house was on fire,的同义句 they were surprised to see that the house was on fire单句和复句的转 he is a tie me to the bed and set this house on fire He woke up ____ his house on fire to find and find finding f 英语单选高手进来( )1.Whatch out!The house is______.A.on fire B.catch 1.He often goes to the cinema on Sundays,____?A.is he B.does 有关过去分词的语法题1 We are pleased to see the problem _____ so quick 单项选择:He went up to the sun and ____ fire down.A.kept B.did C The house is on fire .Stay away____it A.with B.fr
