插頭plug 是很多電子設備必不可少的部件。只有把它與插座連上時，設備才能通電;相反，如果把插頭拔下來，設備會停止運行。我們常用表達pull the plug on something “把插銷拔下來”表示停止、阻止某事繼續進行，尤指停止資助某個項目或計劃，從而使該項目下馬。

例句

I'm afraid the university has pulled the plug on the plan to upgrade the computers in the library. We'll have to make do with what we've got for another couple of years.

When the viewing figures fell below a million the TV station pulled the plug on the series.

If you can't make a profit in five years we will have to pull the plug on further investments.

請注意

單詞plug 做動詞時可以指在廣播、電視等媒體上為某產品、活動、節目等大肆推銷。做名詞時它的含義是“宣傳、廣告”。

例句

He's on four different TV programmes today plugging his new book.

I'm going to be giving a plug to a great new film.
