易错句子He made many boast about his success.
正确表达He made many boasts about his success.
boast 作名词表示“自夸的话、吹嘘”时是可数名词，many 后面必须接可数名词复数，所以要用 boasts。汉语名词不随数量变化，学习者容易漏掉复数词尾 -s。

boast 作可数名词单数时，前面必须有冠词等限定词；这里指“一句吹嘘的话”，需加不定冠词 a。汉语没有冠词这一词类，学习者常把单数可数名词的冠词丢掉。

易错句子That's just a empty boast.
正确表达That's just an empty boast.
不定冠词用 a 还是 an 取决于后面单词的第一个音素，empty 以元音音素 /e/ 开头，所以要用 an。很多学习者只看拼写字母，误以为只有 a、e、i、o、u 开头的词才用 an，这里应写 an empty boast。
brag 偏口语、随意，主要作动词，作名词时常指「一句吹牛的话」，可数；boast 作名词更正式，还常指「引以为豪的事物、骄傲的资本」，如 the city's proud boast。日常聊天用 brag，正式书面语或指「值得夸耀的事」时用 boast。
bravado 指心虚或面对危险时故意摆出的逞强架势，含「装出来的勇气」，不可数，不涉及言语上的自夸；boast 指用言语夸耀自己或指值得夸耀的事物。说「吹嘘成绩」用 boast，说「壮胆逞强」用 bravado。
boastful 是形容词，作定语或表语描述人或话语，如 a boastful remark、He is boastful about his son；boast 是名词，需要冠词或所有格，如 his boast that…。中文说「他很爱自夸」要用形容词 boastful，不能说 He is boast。
