If someone makes a cold call, they telephone or visit someone they have never contacted, without making an appointment, in order to try and sell something。
如果某人給你打了個“冷電話”(cold call)，就是說他在與你素未聯(lián)絡、且并未預約的情況下貿(mào)然致電或拜訪，試圖銷售自己的商品。
我們常說的“騷擾電話、推銷電話”就可以用cold call來表示。其名詞形式為cold calling。
例如：
She had worked as a call center operator making cold calls to sell life insurance。
她在一家呼叫中心做電話員的工作，專門打推銷電話賣人壽保險。
