单选题 The new washing machines are being ______ at the rate of 50 a day in this factory.
A. turned off B. turned down C. turned out D. turned in

【正确答案】 C

【答案解析】[解析] 本题是说这家工厂正以每天50台的速度生产着这种新型洗衣机。C项“turn out(工厂)生产，制造(产品)；(学校)培养(人才)；驱逐，使离开；关掉，旋熄”符合题意。其他三项中，turn off“关，关闭；转到另一条路”；turn down“关小，调低；拒绝”；turn in“上交，交还；上床睡觉”都与题意不符。
