gravity

1. [U]地心引力,重力 on the earth pulls them towards the center of the planet, so that things fall to the ground when dropped
2. [U]严重性; 严肃,庄严 importance seriousness; solemnity

• grasp the gravity理解严重性
• keep one's gravity保持庄重
• realize the gravity of the position认识到情况的严重性

• increasing gravity日趋严重

• by gravity由于重力
• with gravity严肃
