问题 It can be seen from the passage that ______.
Usually you will not get a shock by touching the electric ray in one place only because ______.

选项 A、the current in one place is not strong enough to give a shock
B、the fish’s electric cells are filled with jelly like substance
C、to complete the circuit, you have to touch the fish in two places
D、a torpedo’s electric cells contain more than one electric plates

答案C

解析 本题要求了解文章的细节。这一题主要是对细节部分的考查。第二段中的最后一句活详细地写道,“通常需触摸鱼的两边从而使电路循环完成,这样才会感受到电击。”从这里的completing the circuit(完成循环),我们不难看出C项是正确的。
