【解析】本文是一篇说明文。本文表明近几年来，中国的沙尘暴发生次数增多，并表明了发生的原因，以及解决方法，呼吁人们一起来阻止沙尘暴的恶化。

1.考查时态。In recent years表明了在近几年的时间里，中国经常发生沙尘暴，因此需要用现在完成式。即have occurred.

2.考查定语从句。根据上文的理解，应该是沙尘暴所带来的影响，引起我国的广泛关注。Sandstorms 是先行词, 定语从句中又缺少定语，故填whose。

3.考查非谓语动词。分析语法，因为主语people和动词make是主动的关系，所以用 making作状语。故填making。

4.考查that引导表语从句。that引导表语从中，表语从句中又不缺少成分。故填that .

5.考查副词。为了有效地阻止沙尘暴，用副词efficiently修饰动词prevent。故填efficiently。

6.考查固定搭配。keep…from 阻止…不被…，固定搭配。故填from。

7.考查被动语态。fences和build 之间应该是被动，意思为，更多的绿色防护网应该被建立，should+ be+ build 。故填. be built 。

8.考查连词。连词and用于衔接两个相互联系的句子。通过分析句子结构我们指导空格前后是两个具有联系的完整句子，因此需要一个连词来连接，故填and。

9.考查动词不定式to。分析句子意思为：行动起来，尽我们所能的来阻止沙尘暴。.to prevent 表目的。故填to prevent 。

10.考查句意理解。在不久的将来，我们所期待的美好的一天就回到来。will come 做谓语，表示将来不久就会到来。故填will come 。
