mass詞義知多少
1. mass常作可數(shù)名詞,意為“團;塊;堆”;用作不可數(shù)名詞,指物理術(shù)語中的“質(zhì)量”。如:

一大塊巖石從懸崖上掉了下來,堵塞了道路。
A liter of gas has less mass than a liter of water.
一升汽油的質(zhì)量比一升水的質(zhì)量小。
2. a mass of (也可用masses of)表示“大量;大批”,既可修飾可數(shù)名詞,也可修飾不可數(shù)名詞。如:
I’ve masses of work to do.
我有許多的工作要做。
There were a mass of children in the yard. 院子里有一大群孩子。
