1. This is his only request that the room_______after being used .A.be cleaned B.would be cleaned C.is cleaned D.will be cleaned 答案选A ，为什么 ？request 还有order有啥用法 ？这句话什么意思？这是request虚拟语气的用法，request + that + 从句+ (should) + V原型，这句话的意思是他唯一的要求就是希望这间房间在被用完之后能够被重新整理干净。 有类似用法的词还有suggest,require,recommend等等。 order sb sth, order sb for sth, in order to do sth。 request sb to do2.contain 和 include的区别？contain，include的区别：都有“包含”的意思，但contain可用于表示包含所含之物的的全部 或部分，而include则只能用于表示所包含之物中的一部分。例如：The parcel included a dictionary. 那包裹里也包括了一本字典。The parcel contained a dictionary. 那包裹里装的是一本字典。3."____polite to the guests,"said my father .A.Please B.Do be C.Are D.Should 答案选A ，祈使句不是可以用Please么？这题就是只能用A啊 ,please,祈使句嘛，就是请对客人礼貌点的意思嘛，其他明显都不行4.___ is reported in the newspapers,talks between the two countries are making progress ,A.It B.As C,That D,which 答案选B ，这是定语从句吗 ？如何判断这个和It is reported that?as这里是正如的意思，as is reported然后要加个逗号再加从句， it is reported that + 从句，这就直接加从句，中间不用加逗号的。5.____was known to all ,William had broken his promise_____he would give us a rise .A.as;which B,As;that C.It;that D.It ;which答案选B ，这句话什么意思？As作为关系代词在这里做什么成分 ？为何后面用that作何成分？ 不是一般都是It was known to all.正如我们所知道的，William原来答应会给我们加工资的，可是他后来食言了（这句本来是定语从句，不好一起翻译，所以分开了）后面that是同位语从句的引导词，连接promise，that后面的从句是补充说明promise，不是修饰它的，所以不是定语从句，如果是定语从句的话，which/that都可以用，但这是同位语从句，同位语从句只用that ,至于是as is known to all还是it is know to all 跟上面第四题的用法是一样的，就是有逗号跟没逗号的区别。
