单选题 Listen to the statement and circle the appropriate letter.

单选题 Why does the old projector need to be renewed?

A、 Because it needs technical people to operate.
B、 Because it wastes too much class time.
C、 Because it cannot stir up students’ interest.

【正确答案】 A

【答案解析】Teaching aids can provide a welcome break for students who have been sitting for a while and listening to an instructor lecture in front of the room. Educators can use various teaching aids besides textbooks to pique students' interest and demonstrate how things work. A projector is often part of a teacher's equipment and is useful to students and teachers alike. It allows classroom PowerPoint or computer presentations and projects images for students. The main downfall is the chance of a bulb going out during class, which can halt the lesson. So this old equipment will be replaced by advanced one because the old one needs specialized people to operate, which is not convenient. Many classrooms have a chalkboard or a whiteboard available for a teacher to use. This equipment allows the teacher to write information for students and does not require preparation. It has some downfalls, such as turning the back to students and costing time. Then the electronic white board will be a better choice, which can make the teaching process more interactive by connecting the computer.
