給你個提綱把.
先表明你的觀點(diǎn)
然后正反：
People think should buy a car for the following reasons:
1 convinent to work and travel
2 some people just want to show off(炫耀)
On the other hand,some holds that we should not buy a car:
1 to protect our invironment/car consume oil and polute air
2 it's hard to afford the cost of car oil,the oil price is high.
All in all.最后再次表明你的觀點(diǎn)那你認(rèn)為買車好還是不好咧QAQ，我不曉得啊。。我認(rèn)為不買車好。主要是買不起。嘿嘿。坐公交車挺好的，節(jié)約型社會嘛。(*^__^*) 嘻嘻……
