首先先要说明越来越多的人拥有了私家车。(必然趋势)
First there r more and more families own a car or more.
解释为什么会有这样的趋势。
原因 1私家车比较方便 2国名生活条件的提高 3身份的象征 等等。
Because it's more convenient to hang out when u have car. u can go anywhere u want and no need to worry about u will miss the train or bus and then wait for a long time.(因为当你拥有一辆车时，出游更方便，不用担心耽误火车或者巴士，然后再花很多时间去等)
otherwise there are more and more people get rich now. The cars r not like before that only a few people can buy.And some people think get a car is a sign that u r one of the rich guys.(另外越来越多的人变的富有，车子也不想从前只有少部分人能买到，而且一些人认为有辆车是富有的标志)
然后叙述一下车子的弊端
弊端 1污染环境 2交通堵塞 3停车难
But as we all know the Car exhaust lead the problem of Global Warming.(但是众所周知，汽车的废气导致了全球变暖)
And too manys cars in the road cause the Traffic jam. (而且太多车在路上造成交通堵塞)
another problem is we need more place to parking the cars. The cars Occupy more space with our public space.(还有一个问题是我们需要跟多地方停车，车子占据了我们更多公共空间)
接下来阐明你的观点
1 支持私家车 2 不支持私家车 (在这里建议选择第二个，因为在环保的大前提下，低碳生活最重要。)
And my opinion is cars bring us the convenient but it also bring the Environmental issues.In the long term i think we should contral the number of cars.(我的观点是，汽车带给我们方便的同时也带来了环境问题，从长远角度看我们要控制汽车数量)
最后点题
we cant stop that more and more families own a car but we need consider the problem that cause from cars.(我们无法阻止越来越多的家庭买车，但是我们至少要考虑下车子带给我们的问题)
