　　4. Longjing tea and Wuyi tea arc both famous, but which do you think tastes_____?
　　A. well　　B. good　　C. better　　D. best
　　考查系动词后接表语的用法。因本句话是要比较两种茶，因此选择good的比较级better为taste的表语。答案为C。
　　5. The question is _________ it is worth doing.
　　A. that　　B. what　　C. if　　D. whether
　　考查引导表语从句的连词的用法。引导表语从句的连词有that和whether。That作为连词，在句中不作成分，没有词义，不可省略。但whether表示“是否”的含义。答案为D。
　　6. They shouted for help as loudly as__________．
　　A．they were likely　　B．they can
　　C．they could　　　　　D．they were possible
此题的正确答案是C（they could），句中As loudly as they could相当于as loudly as possible，句中是比较状语从句。as+ adj．／adv．+as one can这一结构意为“尽可能地……，尽力地……”。选项A中likely（adj．）表示可能性，而非能力，因此不妥；选项B中用can，与谓语动词时态不一致，应排除；选项D中possible单独使用正确，但they were possible是明显病句。如：
　　He began to run as fast as he could．她开始尽快地跑。
　　There is nothing we can do but wait as calmly as we can．除了尽量冷静地等待，我们无事可做。
　　7. 句型转换：
　　It seemed that the workman hadn't fixed up the pipe.
　　__________________________________________________________
　　__________________________________________________________
　　__________________________________________________________
　　此题中的句子可以改写成以下三句原意不变。
　　l．It appeared that the workman hadn't fixed up the pipe．
　　2．The workman didn't seem（或：seemed not）to have fixed up the pipe.
　　3．The workman didn't appear（或：appeared not）to have fixed up the pipe.
　　It seemed+ that－clause和It appeared + that－ clause意义相同，appear和seem都作“似乎、显得”解，由于that－clause中的谓语动词用了过去完成时，表示其动作发生在谓语动词seemed之前，两个动作有先后。因此，改写句子时，用 the workman作主语，seem或 appear后面的动词不定式要用完成式。如：
　　He appeared not to have heard what had been said．他似乎没有听见　说过的话。
　　She seemed not to have grasped what I really meant．他似乎没有抓住我真正的意思；
