648.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 damage be compared with those of a control population.
(A) to be tested for chemically induced damage be compared with
(B) being tested for damage induced chemically are compared with
(C) being tested for chemically induced damage should be compared to
(D) being tested for chemically induced damage are to be compared to
(E) that is to be tested for chemically induced damage are to be comparable with

Ans:A
我的問題是:
it is important that s+v ，that子句裡是用祈使句嗎?

[yutsang_0611]

是的
應該說it is important that S + V 可以用直述句也可以用祈使句，
用那一個就要看句意了
[Longman]
(直述句)It's vitally important that you understand the danger.

以下為大全注釋：
Choice A is best because the infinitive to be tested and the subjunctive be compared are correct for describing a hypothetical course of action. Also, compared with rather than compared to is preferred when a comparison is intended, as here with chromosomes, to reveal differences among things of the same order. Choice B lacks the infinitive and subjunctive forms, and damage induced chemically is more awkward than the comparable phrase in A. C and D have being instead of to be and to instead of with; also should and are to do not belong in the subjunctive. E is wordy, are to again intrudes, and comparable changes the meaning of the statement. This question is difficult.

另有一個問題我困擾很久了。就是在"比較"時，
compare with 優於 compare to 嗎？
一般compare A with B 是比較AB，而compare A to B 是比喻
但是compare A to B 也有比較的意思，是不是因為這樣，compare
with才是相對的優選呢？

我是偏向都用compare with，即然compare to 會有二種意思，那就別用了
但是假使題目都是compare to，那就沒得選了

這是我做題目時的想法:
compare A with B --> A與B同種東西, 同中求異
compare A to B --> A與B不同種的東西, 異中求同
還請大家討論討論~
