30. Before giving my opinion，I think it is important to look at the arguments on both sides.
31. This view is now being questioned by more and more people.
32. Although many people claim that，along with the rapidly economic development，the number of people who use bicycle are decreasing and bicycle is bound to die out. The information I've collected over the recent years leads me to believe that bicycle will continue to play extremely important roles in modern society.
33. Environmental experts point out that increasing pollution not only causes serious problems such as global warming but also could threaten to end human life on our planet.

36. Despite many obvious advantages of bicycle，it is not without its problem.

43. As for me，I'm in favor of the opinion that education is not complete with graduation，for the following reasons：
44. It is commonly accepted that no college or university can educate its students by the time they graduate.
45. Even the best possible graduate needs to continue learning before she or he becomes an educated person.
46. It is commonly thought that our society had dramatically changed by modern science and technology，and human had made extraordinary progress in knowledge and technology over the recent decades.

50. For people who want to adopt a healthy and meaningful life style，it is important to find time to learn certain new knowledge. Just as an old saying goes：it is never too late to learn.
