He_(appear) in several films so far.9The telephone_(ring) four times in the last hour, and each time it_(be) for my roommate.10Do you know the Summer Palace at all?No, it is the first time I_(come) here.答案与解析1have gone考查动词时态。句意：房价已经下降了，但是我怀疑是否会这样保持下去。说话时价格已经降了，动作
4、已经完成，而且降价肯定对现在甚至以后造成了影响，因此用现在完成时。2have arrived考查动词时态。句意：当你到家的时候，给我打个电话让我知道你已经安全到家了。3have finished考查动词时态。句意：什么时候我们再开始我们的生意？到完成我们的计划时。在状语从句中，经常用一般现在时表将来时，用现在完成时表将来完成时，此处为until引导的时间状语从句，故用现在完成时。此句完整的句子是We shant restart our business until we have finished our plan。4is being rebuilt考查动词的时态和语态。句意：他们现在暂时和父
5、母一起居住，因为他们自己的房子正在重建。根据句意可知，应使用现在进行时态，且house与动词rebuild之间为被动关系，故使用现在进行时态的被动语态。 5have been working由时间状语for almost two years可知应该是现在完成时，此处强调动作的持续，用现在完成进行时。6has been working由第二句知，“work”这一动作现在仍在进行，可能还会继续下去。现在完成进行时表示一个动作从过去持续到现在并有可能继续下去。7had seen句意：Sofia看了看四周所有的人。她印象中她以前见过这些客人中的大多数。设空处所缺的动词表示的动作发生在主句谓语动词动作之
6、前，同时有时间状语before，故用过去完成时。8has appeared考查动词时态。句意：我弟弟是个演员，到现在为止，他已经演了好几部电影了。句中有时间状语so far，意为“迄今为止；到现在为止”，可确定用现在完成时。9has rung；was考查动词时态。句意：电话在一个小时里响了四次，每次都是找我室友的。句中有时间状语in the last hour，所以用现在完成时表示已经完成的动作；每次都是找我室友的，说的是过去的情况，因此用一般过去时。10have come考查动词时态。句意：你了解颐和园吗？不了解。这是我第一次到这里来。It is/was the first/second.t
7、ime that sb.have/had done sth.是表达“这是某人第几次做某事”的固定说法，在time后的定语从句中要用完成形式，由于主句用一般现在时，故用现在完成时。.改错1. All these years they are contributing articles to our magazine._2.
