观点1

我们必须承认的是多造路对于那些开私家车和居住离市中心比较远的人来说是有很多好处的。

这是因为公路更多，交通堵塞会很大程度上得到缓解，这就意味着人们能更快到达他们的工作地点。

观点2

但是这样的行动会增加选择开私家车的人，给环境带来负担。

这是因为在21世纪汽车尾气是环境污染最主要的来源，并且因为它不可见，人们没有办法察觉。

提升公共交通还能带来很多其他的好处。

开头段

Although building more roads can

effectively alleviate traffic jam,

I firmly believe that a better

network of public transport can

bring more benefits to the public.

主体段观点

It has to be admitted that building more

roads is beneficial for people who drive

private cars and those who live far

away from the city centre.

解释说明1

This is because with more roads

available, the traffic jam will be

significantly mitigated, which

means that people can commute

to their workplace faster.

过渡句

However, this move will significantly

increase   the number of people who

choose to drive cars, which

exacerbates the   pollution of our

environment.

解释说明1

For example, in the 21st century

emission from cars has become

the major source of air pollution,

and as it is   invisible, few people

are aware of it.

解释说明2

There are a multitude of benefits of

creating a   better network of public

transport.

结尾段

In conclusion, the government should

upgrade   public transport regularly

rather than investing in the

construction of  roads.
