this is called a power strip, well in most cases, there’s only one wall outlet in the parts of the house, so it’s not enough to power up all the electrical appliances and electronic devices at the same time.
    So we need an extension to the wall outlet, which can let you plug in three or more devices, and now my phone and laptop are dying, so let’s plug them in together to get’ em charged.
    这被称为插线板，在大多数情况下，房屋的某些部分只有一个墙壁插座，因此同时为所有电器和电子设备供电是不够的。
    所以我们需要一个墙上插座的扩展，它可以让你插入三个或更多的设备，现在我的手机和笔记本电脑都快没电了，所以让我们把它们插上充电吧。
