8、救了成千上万本来会死去的孩子。句中的up to now是现在完成时态的一个典型标志，此句要用现在完成时，正确答案为D项。5B句意：当你到家的时候，打电话给我让我知道你已经安全到家了。此处B选项使用现在完成时表示将来完成，译为“已经”。A项表示进行或将来；D项表示将来；C项为过去完成时，表示过去的过去，因此C项也可被排除。根据句意以及时间状语When you are home可知应选B。6C考查动词时态。句意：看！有人把沙发清理干净了。哦，不是我。我没有做。“把沙发清理干净了”强调对现在的影响，现在沙发是干净的，故用现在完成时。7D句意：我们最近花的钱太多了。是啊，这并不吃惊。我们的亲戚朋友不断
9、地来玩啊。根据句意可知，“来玩”这个动作是从过去某一时起，到现在一直在重复的动作，所以应用现在完成进行时。are coming 进行时表将来；had come 过去完成时，表过去的过去； were coming 过去进行时表过去将来。8D句意：为什么你想为我们公司工作？这就是我一直在寻找的工作。题干中用的是一般现在时，C项是过去完成时，动作发生在过去的过去，句中对应着的应是一般过去时，故可排除C项；A项是过去时，表示过去某一瞬间完成的动作，与现在无关，由此可排除A项；B项是将来时，与语境意义不符；D项是现在完成进行时，表示一个动作开始于过去，持续到现在，有可能继续下去。所以D项是正确答案。9A
10、句意：约瑟夫自从上个月就一直去上夜校，可是他仍然不能用俄语说“你叫什么名字？”从句意可知所表示的动作是从过去发生到现在一直进行着，而且还有可能继续下去，所以要用现在完成进行时，因此选A项。10A根据题干中的lately( recently最近，近来)时间提示，应该选择与现在完成时相关的时态，所以选A。11C句意：太棒了！我以前从来没有喝过这么特别的饮料！我很高兴你能喜欢。Never 位于句首，要倒装，根据句意应该用现在完成时，所以选C。12D句意：直到我们完成我们的计划，才重新开始我们的业务。将答语补充完整为：We shall not restart our business until we
11、 have finished our plan.表示到将来某个时间完成的行为通常用将来完成时，而句中until引导的是一个时间状语从句，故用现在完成时代替将来完成时，由此可知选项D正确。13B句意：我没要名单。它怎么会在我的桌子上面呢？我刚才放在上面的，以防你用。此时，名单已经在我桌子上了。 所以用现在完成时。14D句意：他的第一部小说自从上个月出版以来就受到了好评。since 从句用一般过去时，主句用现在完成时。15D句意：这是自从我到了这个学校以来所参加的最有教育意义的一次讲座。 since 从句用一般过去时，主句用现在完成时。16B句意：许多年来，人们都一直梦想着电动汽车。然而，制造它们
