Also when it comes to cell phones, on all phones, if you want to redial somebody that you've dialed before, all you have to do is hit the call button, and it puts the last phone number into the box for you, and at that point you can hit call again to actually dial it.
还有当说到电话，在所有手机上， 如果你想要重拨，给之前打过的某个人， 所有你要做的就是，按拨打键， 接着手机会为你添加那个号码。 然这个时候你按拨打键，再次拨打。
