托福口语真经
The school computer lab has planned to add a few evening classes to its opening schedule. Usually, the computer lab only opens from 9am to 5pm on weekdays. Nevertheless, because of the rapid increase of student numbers in recent years and the limited seats of the computer lab, it has become progressively difficult to meet each student’s requirements. Therefore, in order to be able to serve the students better, the administrators have decided to add evening classes in the computer lab from 6pm to 9pm, Monday to Friday.
