问题 You are required to (fast) ______ the seatbelt when driving so as to protect yourself.
选项
答案fasten
解析 本题考查的是固定结构的用法。“be required to do sth.”是固定结构，此处的to为不定式符号。因此需填形容词fast的动词形式。fasten的原形。英语中很多动词是通过添加后缀-en构成的，如形容词fast的动词形式，字母t在fasten中不发音。类似的动词还有：broad—broaden，less—lessen，sharp—sharpen，loose—loosen等。
