【解析】

試題分析：氣候變化引起海水上漲導(dǎo)致沿海地區(qū)淡水含鹽量過高，文章介紹了一種由電腦控制水鹽度的種植蔬菜的裝置。

【1】used.考查過去分詞。此處是過去分詞作定語，意思是“在海邊農(nóng)場上被使用的淡水含鹽量提高”，故填used。

【2】gradually.考查副詞。句中修飾be unable to用副詞，指逐漸地不能使用，故填gradually。

【3】mixture.考查名詞。此處由a和of修飾，故用名詞，指一種混合物，故填mixture。

【4】to grow.考查不定式。此處是動詞不定式作目的狀語，指“為了種植可口的蔬菜”。故填to grow。

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

【6】controlled.考查被動語態(tài)。此處指“灌水量和水的含鹽量是被電腦控制的”，此處是被動語態(tài)，動詞用過去分詞，故填controlled。

【7】those.考查代詞。those指代前面的the vegetables，用復(fù)數(shù)。故填those。

【8】better.考查比較級。此處指“這些蔬菜嘗起來更好”，含有和以前比較的意思，故填better。

【9】where.考查定語從句。此處where引導(dǎo)的是一個非限制性定語從句，先行詞是Pakistan，先行詞在定語從句中做狀語，故填where.

【10】was damaged.考查時態(tài)語態(tài)。此處指“很多土地被毀”，所以用被動語態(tài)；根據(jù)時間狀語last year，要用一般過去時態(tài)。故填一般過去時的被動語態(tài)was damaged。
