二、英譯中：（25 分）A migrant worker is a person who is to be engaged, is engaged, or has been engaged in a paid activity in a country of which they are not a national. Migrant workers often face challenges to and abuse of their human and labor rights in the workplace. This can occur in many ways.

Third, migrant workers may suffer unequal access to employment rights, social security, trade union rights, or access to legal proceedings. Last, migrant workers may encounter workplace racism or discrimination.
