Question

Nowadays people are putting our water supply in danger, because they use too much water or throw rubbish into the river. You may wonder how paving(铺砌) a road can lead to less usable fresh water. A major part of thewaterweuse every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave，the less water can flow into the ground to become groundwater.

Human activity is not responsible for all water shortages(短缺). Drier climates are of course more likely to have droughts(干旱) than areas with morerainfall，but in any case, good management can help to make sure there is enough water to meet our basic needs.

Thinking about the way we use water every day can make a big difference，too. In the United States，a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live，but there's a lot we can do to lower the number.

You can take steps to save water in your home. To start with，use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher (洗碗机)only when it is full. Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.

文章的主题句的出现还有其他形式：

1.藏龙卧虎式： 即主题句隐含在全文当中，没有明确的主题句。阅读这样的文章，要求考生根据文章的细节来分析、概括推导出文章的主题。具体方法是：首先弄清楚各个段落讲了哪几个方面的内容，这些内容在逻辑上有什么联系，寻找共同点,然后加以归纳形成主题。

2．首尾呼应式： 在有些文章中，为了突出主题，作者在文章开头提出主题，接着进行阐述或论证，在结尾时再次点出主题，这种首尾呼应的写作方式也很常见。值得注意的是，前后两个主题句不是简单的重复，再次出现的主题句往往是前面主题句的进一步引申或发展。

3. 开门见山式：主题句出现在文首。开门见山，提出主题，随之用细节来解释、论证或发展主题思想。这种写作手法叫做演绎法，在英语文章中尤为常见，这种文章的主题句最容易找到，故主题思想显而易见。
