B．当振子运动到B时撤去电场，振子的振幅将变大

C．当振子运动到C时撤去电场，振子的振幅将变小

D．当振子运动到C时撤去电场，振子的振幅将变大

Today, we’ll be discussing EQ: emotional intelligence quotient. Your emotional intelligence quotient seems to indicate how well you (1) your own emotions, and bow well you (2) to others.
EQ is not exactly a new idea, but the (3) itself is a new one. People have realized the way you control your feelings is just as important as your (4) — maybe even more important.
