aggravate = ag(一再) + grav(重) + ate(使) = [病]加重,恶化
gravel = grav(重) + el(人或物) = 稍重的物体→砾石
accreditation = ac(加强) + cred(相信) + ity(表性质) + ate(表动词) = 加强信用→委派
acidity = acid(酸) + ity(表性质) = 酸的性质→酸性

常考释义
Now, even though it may be difficult to understand how a huge mass of ice can move or flow, it’s another word for it, it’s really known that no secret that the glaciers flow because of gravity.
现在，即便了解大型冰川如何移动或漂浮这个现象有些困难，而这已经不再是一个秘密，冰川其实是靠地心力来漂浮的。
