2．________by the teacher，Tom got into the classroom from the back door quietly.
A. To avoid being seen C. To be avoided seeing

B．to lock D．locked
答案 D [句意：——他不可能在家，因为他的门是锁着的。——他经常锁着门在家工作。考查with的复合结构，with的宾语是the door，和lock之间存在逻辑上的动宾关系，所以选择过去分词充当宾补。]

答案C [考查非谓语动词辨析。在本题中can’t help是“不能帮助做”，后接(to)do；第二空be busy要接v.-ing形式。因此选C项。另外，can’t help只有表示“禁不住……”时，
后面才接v.-ing形式。]
11．The traditional approach________with complex problems in our studies is to

B．having dealt D．being dealt
答案 C [句意：在处理学习中存在的复杂问题时，我们所采用的传统方法是把问题分解成更小的、更容易处理的问题。approach常与介词to连用，而to后要用名词或动名词形式，故答案为C项。]
