完形填空辨析shut down和shut off：Kruger had gone down to the basement to____the wood stove for the
night.A.shut outB.shut offC.shut downD.shut up.为什么选B不选C?不是shut down和shut off都有关闭机器的意思吗?
答
shut off关掉自来水,煤气,收音机等
shut down关掉工厂,引擎.指停产,停工,熄火.Computers can be shut down and mobile phones can be turned off.这里不就用了shut down吗在字典里，有例句是可以互换的，但是我查找了英英字典，shut down----cause to ceaseoperating，operate这个词更侧重机器类吧，所以shut down 也更侧重的是机器的动力，引擎。
shut off----block off the passage through, through通过之义，更侧重的是水不能通过，切断，煤气不能通过切断，炉子切断。
咱们可以单看down 和off的区别，down是向下的意思，所以shut down 有停产，关门窗的意思。
off是断开，切断之意。pay off付清（债务人，债权人的关系切断）有点理解了，还想问一个小问题：柴炉里面是煤气吗？:-D
