1.bare的第一个意思就是not covered by clothes [= naked] 2.race的意思:to compete against someone or something in a race,所以compete的意思要比race广,math是不是打错了,如果是match的话,if you are matched against someone else in a game or competition, you are competing against them 所以compete=be matched against 3.fear是动词或名字,而affraid是形容词,所以不用进行区分
