雅思口语 solution类型题怎么回答？

How can the problems of traffic congestion to be sloved?怎么样才能解决交通拥堵的问题呢？

To tell the truth, it's a bit like pulling teeth sometimes. Even though the government puts new laws into place---for example, the license plate law---drivers get around that by driving a different car on different days. A lot of upwardly mobile people own more than one car these days! 说实话，这是个很难解决的问题。尽管政府颁布实施了一些新的法律条文，如车牌法根据号码规定可出行日期来缓解交通压力，但现在也有很多有钱人不只有一辆车。

(like pulling teeth 极端地困难）

How can we improve people's diet? 怎么样能改善人们的饮食呢？

Well, I think we're already starting to see the light at the end of the tunnel. People are realizing that nutrition is an important aspect of their lives. Whereas in the past, people often ate food on the go, now people are taking more care to eat enough vitamins, complex carbohydrates and protein. There are fewer couch potatoes these days! 我想我们已经看到希望了。人们已经意识到营养在生活中的重要性了。在过去，人们通常很盲目地吃东西。现在，人们则很关注维生素，碳水化合物及蛋白质的摄入，而且整天坐在电视机前面吃薯条看电视的人也少了。

What do you think companies should do to protect the environment? 你认为在保护环境这方面，公司应该做些什么？

Unfortunately, there is no quick fix. One first step could be to reduce energy consumption. For example, they might try using LED lights. Also, they should focus on producing biodegradable /,baɪə(ʊ)dɪ'greɪdəb(ə)l/ materials, which don't take hundreds of years to decompose. 不幸的是，在环境保护方面无捷径可走。首先，应该减少能耗。例如，公司可以尽量使用节能灯。同时，致力于生产无需花费上百年才能分解的生物可降解材料。

（no quick fix 没有捷径）

How can students' discipline be improved? 怎样才能提高学生们的纪律性？

I think we need to explore all avenues. Firstly, discipline needs to start at home. How can teachers be expected to control their students if the parents let their kids run wild?Secondly, although corporal punishment is not an option in this day and age, there should be some measures in place to punish students who act up. For example, detention or extra homework. 我想在这个问题上，我们应该竭尽全力。首先，行为规范需要从家里抓起。如果家长们都纵容孩子，又怎么能指望老师能管理好孩子呢？其次，虽然现在体罚已经不适用了，但仍需要采取一些必要手段，如关禁闭、额外作业等。

（explore all avenues 竭尽所能 ）
