5.C【解析】由交流电瞬时值表达式w=1100√2sin200t(V)可得交流电的频率为10HzP电压有效值为U2=1100V,输电线上的电流I==80A,故A项错误;降压变压器的输入电压U3=U2-Ir=700V,降压变压器原副线圈匝数比n3=70035220;11故B项错误;用电器的额定功率P=Po.6×104W,故C项正确;变压器不改变交流电的频率,所以用电器上的交流电的频率为100Hz,故D项错误。

36.D根据空前“ Nowadays, listening is becoming more and more important in communication...”及空后“Butdon' r worry. There are some tips on how to be a good listener.”可知,D项“然而,很多人无法正确地倾听别人”符合37.A根据空后的内容“很多人假装在倾听,实际上他们希望朋友能停止诉说,这样自己就可以说出自己在脑海中排练很久的话,朋友是能够感受到这种心不在焉的倾听的,而且倾听者也会遗漏听到的话,因为他们没有专注”可知,A项"保持在现场的状态(即要专注地倾听)”符合38.G R# Bj"Don't give advice.
