再小的力量也是一种支持。An energy source is “renewable” when supplies of it never run out and “non-renewable” when one day they will run out.我们称用之不竭的资源为“可更新
资源”。称最终会枯竭的资源为
“不可更新资源”。Language points 1) run out
run out 是不及物的, 后面不能加宾语,
所以没有被动。 run out of 是及物的,
后面必须加宾语。 如：
We have run out of the ink.
= The ink has been run out of.
= The ink has run out.2) renewable/non-renewable
可更新资源/不可更新资源
If I can rephrase what I had just said, I
think our resource is not renewable.
如果我可以把我刚说的话重新措辞一下,
我变为我们的资源是不能再生的。Homework1. Review the new words and
expressions in this class.
