9、題解：1. C本題所說的意思是寬吻海豚與巨頭鯨送食習慣上大相徑庭，這個點令科學家很感興趣。題句表達的內(nèi)容短文中找不到，故答案為C。2. B題句的意思是：RonanHickey分析了愛爾蘭海豚發(fā)出的近2000種不同的方言。這句話與短文中敘述的意思不符。第三段第一句說：RonanHicke分析了愛爾蘭海豚和威爾士海豚（不但僅是愛爾蘭海豚）發(fā)出的近2000種不同的嘯聲（不是方言）。所以，本題選項B是答案。3. A題句表達的意思與第三段第二句所述的內(nèi)容相符。32種嘯聲中有8種是愛爾蘭海豚獨有的。所以答案是A。4. A短文第四段第一句說科學家正在設(shè)法將嘯聲與海豚的行為特性聯(lián)系起來，其中也包括成年海豚與小海豚之間的聯(lián)絡(luò)這個行為。題句的意思與原句的意思相符，所以答案是A。5. C本題所說的態(tài)思是鯨魚能發(fā)出比海豚更強烈的超聲波去殺死獵物。題句表達的內(nèi)容短文中找不到，故答
