问
The diamond is the hardest substance in natures. A B C D 我认为选项 C(substance) 应改为 material。对吗？
答
上题中的 substance 用得对,而 natures 用错了:应改为 nature。因为 nature 作“自然界”“大自然”解时是个不可数名词,没有复数形式,也不带冠词:
-
the beauty of nature 大自然的美
-
Nature is beautiful in spring. 春天大自然是很美的。
-
Man is engaged in a constant struggle with nature. 人类与自然进行着不断的斗争。
当 nature 作“本性”“天性”解时, 则是个可数名词:
Our cat has a very friendly nature. 我们的猫天性很温顺。
练习
