____ is one of good properties of this metal.

____ is one of good properties of this metal.
A、Light in weight
B、Having been light in weight
C、Be light in weight
D、Being light in weight
【正确答案】:D
【题目解析】:本题测试的是语法知识。light在表示“轻”这一含义时是形容词,所以“light in weight”不能作主语;be是动词原形,因此“be light in weight”不能作主语;“轻”是一种状态,因此用动名词的完成式是不正确的;“being light in weight”作为动名词短语,可以充当主语。本句的意思是:“质量轻是这种金属的良好属性之一。”
