Answer 1

【答案】

【1】covered

【2】avoid

【3】still

【4】plenty

【5】cheaper

【解析】本文簡單描述了現(xiàn)在世界上存在的水資源短缺問題。

【1】句意：雖然地球的近3/4被水覆蓋，但我們缺少飲用水。be covered with…意為“被…覆蓋”，故填過去分詞covered。

【2】句意：我們怎樣才能避免嚴重的水資源短缺呢？這一句話缺少謂語動詞，這是在提出疑問，從后面的一系列措施猜出這里提出的問題是如何避免avoid水資源短缺？故填 avoid。

【3】句意：我們仍然沒有足夠的水。從前句的“但是人們對水的需求與日俱增”說明水資源“仍然”不夠，故填副詞still。

【4】句意：大海里有大量的水。plenty of…意為“許多…”，大海里自然有“許多”水，故填 plenty。

【5】句意：如果科學家能找到更便宜的方法，我們就能解決水資源短缺的問題。前面是“海水淡化是很昂貴的”，所以這里是說如果有“更便宜”的辦法或方式就好了，故填比較級cheaper。
