说是“任选一个角度”，但不同的角度的含金量肯定是不一样的。对于新材料作文，我建议使用“线性思路法”，即用简单的流程图表示出材料的意思。例如下面一则材料（这是我们学校的期中考试题~）：
有一家英国报纸以“世界上最大的快乐是什么？”为题，作有奖征答。获奖的三个答案是：1. 一位艺术家殚精竭虑完成了一件作品，望着作品吹口哨；2. 小孩在沙滩上忙了一天，用砂石筑成一座堡垒；3. 外科医生完成了一个历经8小时的手术，终于救活了一条命。
看了这些答案，你有何感想呢？请全面理解材料，选取其中一个角度，谈谈你对快乐的理解。
可以在草纸上理清思路：艺术家——殚精竭虑——作品——快乐；小男孩——忙了一天——城堡——快乐；外科医生——8小时手术——救活病人——快乐。从中归纳出共同点即可得到最佳立意：最大的快乐是付出努力之后获得成果。
对于命题和半命题作文，为了让自己不跑题，最好的方法就是每一段都在段首或段尾点题。其实材料作文也可以这么做。当发现自己快要些跑了可以回评材料，避免跑题。
You can take away our money, house, car, or even our clothes and we can survive. But if our health was taken away, we would surely die. That is why we always try to eat in a healthy way and exercise regularly.
In order to eat healthily, I usually avoid eating food high in fat, like French fries or cookies. I also eat little meat. I eat a lot of vegetables and fresh fruit which are full of vitamins.
Taking exercise every day helps us build a strong body. Regular exercise is an important part of keeping me healthy.
What＇s more, I think friends are an important part of one＇s health. Many studies show that people with a wide range of social contacts get sick less than those who don＇t.
I always feel better when I am with friends than when I am alone. When I am with my friends, I always laugh. Laughing is also an important part of health. I like to laugh with my friends.
By eating properly and exercising regularly, I can keep my body at a proper weight and keep healthy. By spending time with my friends, I can keep my mind as well as my body happy.
These things sound easy to do, but not many people can manage them. I think a strong will is necessary if we want to keep healthy.
