考查词语辨析。 1. turn on意为“打开(电灯、自来水、无线电等)”。如: Please turn the electric fan on.请打开电风扇。 2. turn off意为“关闭(水源、煤气、电灯等)”。如: Don’t forget to turn all the lights off before you come up to bed.你上楼睡觉之前,不要忘记把所有的灯都关上。 3. turn up是指将音量调大些。如: Turn the radio(a little)up so that the students at the back can also hear clearly.请将收音机音量(稍微)开大点,以便后排的学生也能听清楚。 4. turn down意为“关小点(些)”,而不是完全关掉(turn off)。如: We usually turn down the heat before going to bed.睡觉前我们通常把暖气调低一些。 |
