易错句子In 1917, two Bolshevist led the uprising in Petrograd.

正确表达In 1917, two Bolshevists led the uprising in Petrograd.

英语可数名词在数词 two 之后必须用复数形式 Bolshevists。汉语名词没有数的形态变化（“两个布尔什维克”），学习者常因此漏掉词尾 -s；此处主语是两个人，故须用已知的复数形式。

易错句子Lenin's brother became Bolshevist when he was a student.

正确表达Lenin's brother became a Bolshevist when he was a student.

Bolshevist 是可数名词，指“一个布尔什维克成员”，单数泛指身份时前面要加不定冠词 a。汉语“成为布尔什维克”没有冠词，学习者容易直接对译而漏掉 a。

易错句子Many young workers joined in the Bolshevists after the revolution.

正确表达Many young workers joined the Bolshevists after the revolution.

join 表示“加入某个组织、团体”时是及物动词，直接跟宾语，不加 in；join in 只用于“参加某项活动”（如 join in a game）。汉语“加入”是一个词，学习者常误配成 join in，应改为 join the Bolshevists。
