College students' English level is not very high, so they can play some simple games, such as the executioner's game: draw a juicer on the blackboard, choose a word, and let everyone guess from 26 letters. Every time you guess a wrong letter, you will draw a part of the villain, such as the body and hands. Guess this word, and the villain will be saved. If you can't guess the word, the villain will hang. The difficulty can also be increased. For example, after guessing a word, you should say the meaning and part of speech and make a sentence without grammatical errors.
