1．E. 空格1前后句都是用“We 謂語”的結(jié)構(gòu)， 因此B和E可能是答案（句子結(jié)構(gòu)形成排比結(jié)構(gòu)）。B出現(xiàn)在空格中與空格前后句句意不銜接， 而E也是在談及對海洋的利用， 與空格前后句句意自然銜接， 因此E是答案。

B We pollute（污染） the ocean when we use it as a garbage dump（垃圾堆）。
C The area of the sea is becoming smaller and smaller.
D Along with（連同。。。一起） salt， other minerals are left（留下） after evaporation.

B We pollute（污染） the ocean when we use it as a garbage dump（垃圾堆）。
C The area of the sea is becoming smaller and smaller（越來越�。�。
