回答：1 。Are the two glasses believed----------by Tom？ A。 havebeenbroken答案:D 译文:确信两个杯子都是被汤姆打破的吗?分析:sth is believed to have done by sb . 如果事情已经发生，我们要用不定式的完成时态．2. --------Are you sure to help me find_______bed for my new house ? ---------Of couse, but not now ,I''m heading for_____bed and a good sleep. A.a,aB.a,不填 e,aD.a,the答案：B 译文:你确保能帮我找到一张适合我新房子的床吗？　当然喽，但现在不行，我想要上床先好好睡一觉再说．分析：第一空表示泛指，一张床，　第二空是个固定短语上床睡觉的意思．类似于ｇｏ　ｔｏ　ｂｅｄ　．不加任何冠词．　3. ________the house Mr. Zhang has been broken into ? A. When was it that B.When has C. Has D. Had 答案： D译文:张先生的那房子的被（强盗）偷了是吗？分析：Had the house （Mr. Zhang has作定语修饰房子，意思是张先生有的）been broken into ? 　4. Having a trip abroad is certainly good for the old couple, but it remains_______whether they will enjoy it .  en答案: B译文:到国外去旅行肯定对这对老有好处，但是有待于看他们是否喜欢．分析：这里还有待于去看，说明事情尚未发生，所以要用不定式子的被动式．以上几道题目，我总认为第三题题目不完整，所以解释的并没有把握．希望指正！
