问题补充:
Recently some Japanese have been trying to make conflicts with China, attempts we are concerned.
A. whose
B. with which
C. about which
D. about whose
答案:
A. whose
B. with which
C. about which
(答案→)D. about whose
解析:考查定语从句,句意:最近一些日本人想和中国制造冲突,我们非常担心它们的意图,句子的意思是指“Recently some Japanese have been trying to make conflicts with China这件事情”的影响,attempts缺少定语,要用whose从句中使用了be concerned about的短语,effects为介词about的宾语;所以用“介词加连接代词”的形式;选D。
