很难相处。而must,should,would没有这层意思，故选B。 23.C句意：尽管大多数情况下彼得是一个很不错的 人，但有时候他也会很难相处。can在本句中表示理论上的 可能，在本句中意为“有时也可能”。 24.D句意：莉萨可能不想去旅行，她厌恶旅行。may well很可能，极有可能。如：It may well change forever the way you look at Greek art.这很可能会永远改变你对希腊艺 术的看法。 题源2虚拟语气 1.C本题考查的是虚拟语气。此处表示和过去事实相 ·2 反的情况，应该用should十have十过去分词。本来应该做， 而未做。 2.A本题考查虚拟语气与时态。前句表示对过去的 虚拟，而b山t之后表示过去的客规事实，故用一殷过去时态。 3.B would rather后应用虚拟语气，表示与现在时间 相反，用动词的过去式。

主句引导非限制性定语从句。句意为：我们又发射了一颗人 造卫星，这是在今天的报纸上宣布的。故答案远B。 4.D考查定语从句。此处which指代前面整个主句 内容，引导非限制性定语从句。句意：莫言2012年被授予诺 贝尔文学奖，这使得中国长期以来的梦想之一成为现实。 5.C考查非限制性定语从句。由“.has surprised us all”可知从句缺少主语，应选关系代词，that不能用在非限制 性定语从句中，故C项符合题意。句意为：这是她第三次赢 得这个比赛，使我们都很吃惊。 6.C考查非限制性定语从句。从句缺少主语，由选项 可知C项符合题意。句意：据报道，这个城市的空气质量在 过去的两个月中已经得到改善。 7.A考查非限制性定语从句。C项what不能引导定 语从句：D项that不能用在非限制性定语从句中，从句缺少 主语，故用A项关系代词which。 8.B考查定语从句。“that
