    What are some of the advantages of using a cassette recorder?
    Some of the advantages of using a cassette recorder are:
    First, it gives the students the chance to listen to a variety of voices apart from the teacher’s, and it brings native speakers’ voices into the classroom.
    Second, recorded material is useful for listening to dialogues, interviews, discussions, etc. where there is more than one person speaking at the same time. Otherwise the teacher has to act the part of more than one person.
    Third, it is very useful for intensive listening, because the cassette can be stopped and a phrase played over and over again. This kind of listening is called intensive listening.

    Topic 2：My View on College Students’ Use of Mobile Phones　　Questions for reference:　　1) What is the phenomenon of college students’ using mobile phones?　　2) What might be the advantages and disadvantages of their using mobile phones?　　3) What could be done to this problem?

    正确答案： 【参考答案】
    My name is... My registration number is... My topic is: My View on College Students’ Use of Mobile Phones.
    China is becoming a country with the biggest population of mobile phone subscribers and an increasing number of college students are joining the existing users. Statistics show that eight out of ten college students have got one. However, is it necessary for a college student to own a mobile phone?
    In my opinion, there is nothing wrong for a college student to have a cell phone, with is, students will be better connected with friends and parents. What’s more, mobile phones play an important role in graduates’ job-hunting. Therefore, instead of banning the use of mobile phones, schools should take measures to guide an appropriate use of them on campus, For example, students are required to switch off their phones in classrooms and under no circumstances should they use a mobile phone during exams. In some public places, like libraries, a poster can be placed at the entrance to alert library users to switch their phones to vibration mode before they enter the library.
    I believe mobile phones can bring benefits to our students as long as we can make good use of them.
