doohickeys

Finally, the Obama campaign suggests that the 72-year-old Mr McCain is too doddery to understand the doohickeys that modern bankers (and others) use.

最后，奥巴马的团队还暗示说麦凯恩已经72岁了，身体状况和年龄都令他不能理解现代银行家所使用的迷人眼的手法了。

Connecting each of these doohickeys to the computer took two interface boards, more than 200 feet of wire, and several late-night stripping and splicing sessions.

把这些小玩意连到电脑上，总共花了两块介面板、超过60公尺长的电线，以及数个切割黏贴做苦工的深夜。
