DBits of coral.A解析：代词指代题。根据下文的“.use them effectively in the waters off Scotland and then hopefully in the oceans across the world.”可知这里的them指代的是上文提到的Coralbots，因为要用这些东西来修复珊瑚礁。故选A。4We can infer from the passage that Abottom operation has affected most underwater creaturesBbroken branches of coral can regrow if saved in timeChundreds of the coralbots have worked well in the oceansDwith the coralbots all damaged coral reefs can be restoredB解析：推理判断题。根据文章第四段的“.this is not the case for Coralbotsthe robots that can constantly seek out broken branches.A team ofcoralbots，each individually working to simple rules will piece together damaged bits of coral，allowing them to regrow.”判断选B。B(2016河南开封模拟)Nowadays many people are concerned about the problem of what to do with electronic waste such as old
