狼人皮肤披着海牛的狼:几句中译英

可以这样翻：

1..我国是个淡水不足的国家，人均拥有量低于世界水平。
We don't have sufficient fresh water supply in our country. The average per person is lower than that of world level.
[说明]a不要直接用our country做主语，太汉语化。b.average有名词性，平均数，不需加lot.

2. 而且地下水位在不断下降。
And that/what's more/moreover,the level of undergroud water is dropping unceasingly.

3. 每个人都有责任节约用水，并宣传节约用水。
Everyone has the accountability to save water and to propagate the concept of treasuring water.
或
Everyone is accountable to save water and to propagate the concept of treasuring water.
[说明a.accountability 责任义务更贴切些，节约用水只是义务，不是 “responsibilities”职责 b.第二种翻法更地道写，少些汉语化。

4. 注意保护环境，不要使珍贵的淡水资源再受到污染。
we should pay more attention to the enviroment and protect the precious fresh water from being polluted again.

严格的讲pay attention to 才是“注意”的表达。

The average water per person is lower than the average of the world.
