"To clean the classroom" is the Engpsh phrase used to describe the action of cleaning a classroom. This phrase is made up of the infinitive verb "to clean," which means to make something clean or free of dirt, and the noun "classroom," which refers to a room where classes or lessons are taught.
Here are some example sentences using this phrase:
"I need to clean the classroom before the students arrive." (我需要在学生到来之前打扫教室。)
"Can you help me clean the classroom after school today?" (你今天放学后能帮我打扫教室吗？)
"The janitor is responsible for cleaning the classrooms every day." (保洁员负责每天打扫教室。)
Note that "to clean" is an infinitive verb, which means it is not conjugated and is often used with the word "to" before it. In Engpsh, infinitive verbs are often used after certain verbs, such as "need," "want," "have," and "should," to express a purpose or intention.
