1.我觉得adj/doing/done/n + n 天经地义，所以选E作者: StanleyHu 时间: 2014-3-7 20:37
公布答案&解析
1
（1）划线部分在句末，考察句型
（2）看每个选项开头，发现主语不同。
（3）前面有个“unlike a funded pension system”,由此可以确定该句子的主语是social security（system） 而不是 approach 和foundation
（4）因此选E.
2
（1）划线部分在中间，可能考察细节。
（2）前面有Although，是个副词罩，罩住了划线部分前面的句子，因此划线部分所在的句子应该是个没有罩子的完整的句子。BC都有罩子，所以排除BC。
（3）A选项中的until almost 1900，并不清楚修饰哪一句，造成歧义，排除A.
（4）再看DE。划线部分前面有had done，而to do 和doing的区别在于to do 表示未发生，doing表示发生过，因此应该是doing。而且almost是adv，修饰v/adj/句子，所以D中的almost位置会发生歧义。再者，begin to do是固定搭配，不能有副词插入，D选项再次坑了。
（5）故选E.
3
（1）根据划线部分，考察大美句。排除CD.
（2）It在前面并没有指代，排除B
（3）主句的主语是scholar，是人，因此A错。
（4）选择E
4
（1）划线部分在中间，考察细节。
（2）看个选项开头，是adj和ajv的差异，adj修饰n，adv修饰adj/句子，故排除ABC
（3）D中有代词them，排除D。
（4）选择E
5
（1）划线句子在句末，考察句型。
（2）看各选项句首，差异在于罩子。
（3）doing/done/词组在中间，划线部分前面有个名词bans，想到形容词罩修饰名词，且w+be省略。排除DE.
（5）Prohibite from 固定搭配。
（6）选择C 作者: lisida929 时间: 2014-3-7 21:04

求问一下各位：
如何判断应该是adj+adj还是adv+adj？作者: belinda_cao 时间: 2014-3-7 23:13
adj修饰N词是有固定的规则和排序的，印象也有点模糊了。这个点，你有点钻牛角尖了噢。
