第一题是想问A为什么错的~

jeanblanc

so as to 要求前后逻辑主语一致，如果前面名词超过一个，易产生混淆；这里前面有king henry和queen catherine，容易混淆，用so that 结构明确主语更清晰。还有，就是 so as to 一般都是错的 一般gmac 会出so ......as to, 这个情况还有可能是对的，一般 so.....as to 和 so that 放在一起考，这个时候不要 急于选 so that。。。 因为两个选项肯定会有一个更明显的错误，要看那个明显的错误再来作判断。

我一我一我

我感觉Shang前面有China’s first administrators，说明它是个复数的名词

应该是 1977年报告中青年人数的两倍。而不是1977年报告中青年的两。 those只能指代young adults。

jeanblanc

未划线的first administrators和接下来的they developed提示主语不可能是culture，而且一定是复数，所以可知答案一定是D,这里的the shang是指商朝人的意思，前面用were是指过去的情况，后面用are是指现在还以之闻名，时态不同，也不能省略。
