【解析】

试题分析：气候变化引起海水上涨导致沿海地区淡水含盐量过高，文章介绍了一种由电脑控制水盐度的种植蔬菜的装置。

【1】used.考查过去分词。此处是过去分词作定语，意思是“在海边农场上被使用的淡水含盐量提高”，故填used。

【2】gradually.考查副词。句中修饰be unable to用副词，指逐渐地不能使用，故填gradually。

【3】mixture.考查名词。此处由a和of修饰，故用名词，指一种混合物，故填mixture。

【4】to grow.考查不定式。此处是动词不定式作目的状语，指“为了种植可口的蔬菜”。故填to grow。

【5】into.考查介词。divide sth. into...意思是“把某物分割成…”，故填into。

【6】controlled.考查被动语态。此处指“灌水量和水的含盐量是被电脑控制的”，此处是被动语态，动词用过去分词，故填controlled。

【7】those.考查代词。those指代前面的the vegetables，用复数。故填those。

【8】better.考查比较级。此处指“这些蔬菜尝起来更好”，含有和以前比较的意思，故填better。

【9】where.考查定语从句。此处where引导的是一个非限制性定语从句，先行词是Pakistan，先行词在定语从句中做状语，故填where.

【10】was damaged.考查时态语态。此处指“很多土地被毁”，所以用被动语态；根据时间状语last year，要用一般过去时态。故填一般过去时的被动语态was damaged。
