问题 Original usage refers to rivers that ______ . [br] Algae under normal conditions in rivers ______ .
选项 A、consume the available nutrients
B、make the oxygen balance
C、force other organisms out of rivers
D、overgrow and die
答案 B
解析 该句提到的Under normal conditions, algae contribute to the oxygen balance in rivers...明确指出海藻在河里的作用是使氧气平衡，故[B]为答案。[A]、[C]和[D]是针对此句后半句设的干扰项，是海藻数量过多时的情况，故不选。
