Question # 9, your answer = A
In Newtonian laws of motion, <there is a condition and it's converse regarding bodies at rest and bodies in motion>.

A) there is a condition and it's converse regarding bodies at rest and bodies in motion

B) there is a condition and its converse regarding bodies at rest and bodies in motion

C) there are a condition and its converse regarding bodies at rest and bodies in motion

D) there are a condition and it's converse regarding bodies at rest and bodies in motion

这到题没有解释, 答案是C, 我选的A, 怎么看也不明白, converse在这里是名词还是形容词呢, 句子怎么翻译呢, 请NN帮助

试翻译一下.

牛顿运动规则中, 有一个关于身体静止和运动的前提和反前提.

不知道对不对.

什么叫"反前提"呢........还是觉得很费解

这是网上查到的.

Converse

The statement qp is called the converse of the statement pq. A conditional and its converse are not equivalent.

我觉得这句话可能就是要表达p<->q的意思.
