1. Now that we’ve discussed our problem, are people happy with the decisions ________?
A. taking                  B. take                      C. taken                    D. to take
【解析】C。由于名词decision与动词take之间为被动关系，所以只能选过去分词taken，其中taken用作定语，修饰名词decision。句意为：我们已经讨论了我们的问题，人们对作出的决定会满意吗？又如：We couldn’t agree on any of the problems discussed. 我们未能就所讨论的任何问题达成协议。
 
2. For breakfast he only drinks juice from fresh fruit ________ on his own farm.
A. grown                  B. being grown          C. to be grown          D. to grow
【解析】A。由于名词fresh fruit与动词grow之间为被动关系，所以首先可排除选项D。而B和C虽然可以表示被动，但与句意不吻合，因为being grown表示一个正在进行的被动动作，to be grown表示一个尚未发生的被动动作，均不合题意。
 
3. ________ twice, the postman refused to deliver our letters unless we chained our dog.
A. Being bitten          B. Bitten                   C. Having bitten        D. To be bitten  
【解析】B。根据句意，句子主语the postman与动词bite之间为被动关系，所以首先可排除选项C；再根据句意（尤其是注意关键词twice）可知，表示正在进行选项A和表示将要发生的选项D均不合题意。全句意为：邮递员被狗咬了两次之后要我们把狗拴起来，不然就不给我们送信了。
 
4. ________ and short of breath, Andy and Ruby were the first to reach the top of Mount Tai.
A. To be tried            B. Tired                    C. Tiring                  D. Being tired
【解析】B。首先要注意tired与tiring的意思有区别：前者表示“感到疲劳的”，后者表示“令人疲劳的”或“累人的”，根据句意，显然不宜用tiring，故可排除C；由于是与形容词短语short of breath相并列，所以应选形容词tired。句意为：虽然累得上气不接下气，但安迪和鲁比是最先到达泰山山项的。
 
5. Michael’s new house is like a huge palace, ________ with his old one.
A. comparing            B. compares              C. to compare           D. compared
【解析】D。compared with为英语惯用表达，其意为“与……相比”。又如：Compared with many women, she was indeed very fortunate. 和许多女人相比，她的确算是很幸运的了。

6. With the government’s aid, those ________ by the earthquake have moved to the new settlements.
A. affect                   B. affecting               C. affected                D. were affected
【解析】C。根据句意和空格后的介词by短语可知，空格处应填一个表被动意义的选项；同时由于句子中已有谓语have moved，所以空格处不能再用谓语形式，而应用非谓语形式，故选C。过去分词短语affected by the earthquake在句中用作定语，修饰those，句意为：在政府的帮助下，那些受地震影响的人搬进了新家。
 
7. ________ not to miss the flight at 15:20, the manager set out for the airport in a hurry.
