问题描述:

In order to produce more grain,it____________ that the area of farmland____________ .
A.is suggested; being increased B.has been suggested; be increases
选哪个?为什么?

1. 答案选B.
不过楼主可能打错字了:be increases应该是be increased.
2. 翻译:
为了产出更多的谷物,已有建议说这片农田应该扩大.
3. 解释:
1)此处suggest意思为“建议”,其后的从句应该采用虚拟语气.即从句的谓语动词由“should + 动词原形”构成,而should经常省略.
2)选项B中的be increased=should be increased.
