Boiling water with a microwave is remarkably easy. To start, pour the water into a container made of the microwave-safe materials listed above. Make sure the container is not sealed shut. A buildup of hot steam can cause a harmful explosion. Next, put a non-metallic object such as a wooden spoon, a chopstick, or a popsicle stick in the water. This prevents a dangerous problem called "super-heating" by giving the water something to form bubbles on.  Super-heating occurs when water in the microwave heats water past its boiling point and the water is unable to form bubbles because there are no nucleation sites (essentially rough spots for the bubbles to form on). As soon as the water is disturbed or a nucleation site is introduced, the built-up superheated water forms steam very quickly, causing a small explosion of boiling water.  If you don't have any non-metallic objects to put in your water, use a container that has a scratch or chip on the interior surface. This will act as a nucleation site to help the water bubble.

TL;DR in Chinese:
把水倒入一个适用于微波炉的杯子或碗里。 把一个适合微波的干净物体放在水里。
