[求助]XDF蓝皮书

Since chromosome damage may be caused by viral infections,medical x-rays, and exposure to sunlight, it is important that the chromosomes of a population to be tested for chemically induced damae be compared with those of a control population.

A.to be tested for chemically induced damae be compared with
 

B.being tested for damage induced chemically are compared with

为什么选A呢？compared前面那个be 对么？

It is important that ...be...有这种句型么？

后面所比较的东西从句意上来看是同一类型

compared with是同类型比较  强调差异性

compared to是不同类比较 强调相似性

让我做的话 我直接靠这个点排除B  别的我也说不上来。。。

不好意思，我打错了

应该是with,A,B都是的话，应该怎么选择呢？

上过XDF的都知道 出现being肯定错啊

可是出现Being不100％都是错啊。有不少题Being都是对的。包括蓝皮书里就有不止一个呢。

我觉得这是个虚拟语气，是提出一个建议的重要性。
