One major advantage of a mobile phone is that it allows calls to be made instantly from almost any location. This can be vital where emergency services need to be called to the scene of a crime, accident or fire. Another advantage is its convenience for social or business purposes. A further advantage is that a mobile phone can serve as a connection to the Internet, which can be extremely convenient for obtaining information wherever you may be.There are, however, also a number of disadvantages to a mobile phone. The fact that a mobile phone allows a person to be contacted at any time can in itself be a disadvantage. The perceived health risks associated with its use can be another disadvantage. Still another disadvantage is the nuisance it can cause at times when the sound of a phone ringing is irritating, such as in the classroom, during a business meeting or at the theatre.Therefore, a mobile phone has both benefits and drawbacks, but what we should do is to make full use of its advantages and bypass the disadvantages.My View on Multi-media Teaching1. 多媒体教学的优点2. 多媒体教学存在的不足3. 我的看法Multi-media teaching is no longer something new to us. To some degree, it has become part of modern education. However, as is the case with many issues, multi-media teaching has both positive and negative aspects.On the positive side, with the combination of word, pictures, animation, sound, video and etc. multi-media education creates positive atmosphere in the classroom, thus motivating the learners. Another underlying advantage is that multi-media teaching with its rich contents and colorful screen makes learning both instructive and enjoyable.On the negative side, multi-media teaching sometimes lacks classroom interaction between the teacher and learners, which may have a bad effect on improving teaching efficiency. Besides, it takes a considerable amount of time to produce the teaching courseware on the part of teachers, thus drastically multiplying teachers’ working load.No sensible people will deny that multi-media teaching has both benefits and drawbacks but on balance the advantages of multi-media teaching outweigh its disadvantages since such a teaching approach has become an integral part of modern education.。
