参及解析：
。can guess 这一现在猜测是建立在眼前所见情景的基础上的，故用现在进行时。
。expect, intend, want, wish, hope, plan 等动词的过去完成式可表示过去未曾实现的想法、愿望、打算等。 。如主句用将来时，在时间、条件和让步状语从句中要用一般现在时表示将来。又因if 从句是take notice of...的被动语态结构，故选A。
。根据主语与build之间的被动关系和now， 可知要选现在进行时的被动语态；因工厂正在修建，花费一年半应指将来。
。shouldn' t have done 表示\"过去本不应......\"。You did lose your temper 是You lost your temper 的强调形式。
。现在完成进行时表示从过去某时到现在一直在进行的动作。
。句意为：他们（现在）不愿买新衣服，因为他们在攒钱买电视。由此可见，攒钱是现阶段正在进行的动作。
。担心是从过去某时到说话时为止一直在进行的动作，用现在完成时；expect 是在过去某一段时间里（整个晚上）正在进行的动作，故用过去进行时。
。论文已完成，花费一个月时间应指过去；某事花费某人多少时间用 time 结构。
。交通现在已经好了，在此基础上正在变得更好。
。题干没有构成\"过去的过去\"，不可选B。如选C、D则表示动作已完成，与have no idea相矛盾。过去进行时表示过去某段时间或某一时刻正在进行的动作，不涉及结果，正好附合题干语境。
。by then 是指将来的时间状语，排除A。再由句意可知，meet指的是到了十点钟时将正在进行的动作。 。问句问的是前天回来之前去了哪儿，故用过去完成时。注意had gone表示人未回来，与第一句相矛盾。 。for＋时间段表示从过去某时延续至今的动作或状态，用现在完成时；meet发生在got to know 这一过去动作之前，用过去完成时。
。用一般现在时表示现在的特征或状态。
。come, go, leave, arrive, take 等动词常用进行时表砂将来。
。表示过去没有做某事应用去时。又因句子没有\"过去正在进行 \"之意，帮排除A。
。问对方\"去了哪里\"，指的是从过去某时到现在为止的动作，用现在完成时；第二个空格是与过去事实相反的虚拟语气和主句，条件状语从句If I hadn' t got stuck in the heavy traffic 被省略。 。在一个国际会议上被介绍显然发生在过去。
。此句为复杂特殊疑问句结构，即\"疑问词＋do you think (believe, suppose, expect, imagine, say, consider, guess等）＋其它（陈述语序）\"。
