Task1
Should schoolrequire its students to participate in 40-hour-long community work?
Sample response:
Inmy opinion, aside from doing schoolwork and studying, students should also participate in various extra-curricular activities among which doing communitywork is a quite good choice. For example, the students in an internationalschool in Shanghai are required to perform a certain number of hours of communityvolunteer work per semester, which is as well as a graduation requirement in thisschool. There are various community work for the students to choose, such as localanimal shelter, charity stores, tutors and many others. By being involved incommunity work, the students have strengthened their sense of responsibility and interpersonal skills. Take a friend of mine as an example, he chose to workas a volunteer to teach people how to play table tennis at the recreation center on weekends. He is very popular there and has made many friends.
Task2
Do you agree ordisagree the following statement? People should retire after 65.
Well, I agree that people should retire after 65 due to the following reasons.
First of all, ageis irrelevant to a working life, people become old does not necessarily mean they are going to be sick. In fact, many old employees are still physically strong. So they can still work as well as before. Besides, in our agingsociety, in order to support more and more retired and old people,it is atendency to require people to continue working for more years. Last but not least ,older employees have a great deal of knowledge and experience which can be a loss to a business or organization if they are made to retire earlier.
