"Join", "enter" 和 "go into" ...

"Join", "enter" 和 "go into" 都可以用来描述进入某个职业或行业，但它们在用法和含义上略有不同。

"Join" 常用于表示加入一个组织、机构或团体，例如参军、加入学术社团等。因此，在职业方面，"join" 通常指融入某个行业的群体，成为其中的一员。例如：

After completing his studies, he joined the accounting profession and became a certified public accountant.

"Enter" 常用于表示开始从事某种工作或活动，尤其是首次进入某个领域或行业。例如：

She entered the field of journalism as a reporter right after graduation.

He entered the legal profession after passing the bar exam.

"Go into" 也可以表示进入某个领域或行业，但更强调的是从事某项工作或活动所需要的决定或行动。例如：

After finishing high school, she decided to go into medicine and pursue a career as a doctor.

He went into politics at a young age and was later elected to Congress.

综上所述，三个词都可以用于描述进入某个职业或行业的过程，但具体使用时应根据语境和惯例进行选择。
