问题 As I sea urchins are becoming scarcer, divers are (i)______to more dangerous depths to retrieve them, (ii)______the potential for diving injuries.

选项

答案B,E

解析 As说明前后同义重复。前文说海胆越来越少,所以潜水员要找到它们就必须“下潜”到更深的地方。第一空填入一个表示“下潜”的词。return返回,descend下降,climb攀爬。答案选B。因为潜到更深的地方,所以潜在的潜水伤害就会“增加”。第二空填入一个表示“增加”的词。lessen使减少,increase增加,belie不一致。答案选E。
