(E) According to the National Pasta Association, per-capita consumption of pasta in the United States is already approaching 19 pounds a year and will reach 30 pounds a year by the twenty-first century.
答案给了E

我觉得A对 E毕竟改变了句子重心 

per-capita consumption of pasta 啊

白勇的书说which就近修饰United States 明显人家定语从句主谓一致已经指示了是单数的per-capita consumption of pasta 是主语

A介词B，which定语从句  结构 白勇自己说是根据主谓一致判断的

而且E的时态 is already approaching 明显很怪

不好意思,lz你贴的太小了,实在看的费劲.

which是有可能指代the US的啊, 难道这个不是单数吗?

A中还有个问题, 假设没有which的毛病, 你前面在定语从句里说他是has been, 后面在主句里又说他achieves, 一个主动一个被动, 你说合适吗??

但是E就解决了这个问题!

UNITED STATES 都当复数来解的（OG哪一道想不起来了）

还有has been是现在完成进行时 ，表示由过去开始一直持续到现在的动作，是主动

从没听说过UNITED STATES 都当复数来解, 请拿出证据来!

事实上, the United States绝对是个单数词! 哪里有第二个美国? 在考试中做题, 这一点就可以秒杀这个选项.

其次, 主动被动的是我错了!

不过为什么要用现在完成进行时呢? 我觉得这么用不好, 明明是普通的进行时就可以了, 当然考试的时候我时不会去想这个问题的,主要时靠第一条.

According to the National Pasta Association, per-capita consumption of pasta in the United States, which has already been approaching 19 pounds a year, will achieve 30 pounds a year by the twentyfirst century

这里的which指代了united states，指代错误。
