The experiment shows that proper amounts of exercise, if ___ regularly, can improve our health.

A．being carried out

B．carrying out

C．to carry out

D．carried out

答案

解析

本题考查if条件句中的省略情况。本句的句子的主语是theexperiment；谓语动词是shows；that引导宾语从句,宾语从句的主干事：proper amounts of exercise can improve our health,if_____regularly是插入的条件从句,从句的主语是proper amounts of exercise,此时应用it代替前面提到的主语,条件句的主语与主句的主语一致,并且含有is,故省略了itis,完整形式是：if it is carried out。句意为：这项实验表明,适当的运动,如果有规律的进行,能够有助于我们的身体健康。
