Q30:

The ancient Anasazi harvested such native desert vegetation as the purple-flowered bee plant, what they now commonly call wild spinach in northern Arizona and other parts of the southwestern United States.

1. what they now commonly call
2. a plant that they now commonly call
3. now commonly called
4. and is mow commonly called
5. which it is now commonly called

Answer is C

Why not B, 前面有个a plant不是更清楚吗？

1. have to know a great deal more than now about the social and economic
2. have to know a great deal more than they do now about the social and economical
3. would have to know a great deal more than they do now about the social and economical
4. would have to know a great deal more than they do now about the social and economic
5. would have to know a great deal more than now about the social and economic

Answer is D

为什么要用would have to know? I choose B

还是不懂，再清楚点行吗？再讨教！

之前难道都没人讨论过这道题，哪为nn给个之前讨论的连接吧

有一原则表示若分词无法表述原文句意时才用that

但本题使用分词表述并未违反句意所以相较于前者更clear

还有一点是句中若有不明的指代尽量少选..否则易产生歧义…….

第二道很简单就是考用字精确性问题

economic vs. economical

后者不能用以表述经济
