Sunburned skin has become red and sore by being in the strong heat of the sun for too long, or is very suntanned.

When you go out in the hot sun, you should always put sunscreen on your skin to avoid getting sunburned. 大热天外出时应该涂上防晒霜，以免皮肤被晒伤。

Fishermen with sunburned faces sat on the beach mending their nets. 脸被晒得黝黑的渔民们坐在沙滩上修补渔网。
