第1题：

Ronan Hickey analyzed almost 2000 different dialects of the bottle-nose dolphins.

A．Right

B．Wrong

C．Not mentioned


正确答案：B
解析：问题中的关键词组是of the bottle-nose dolphins。利用问题句中的特征词Ronan Hickey(人名)和2000 different(不同的)dialects为答案线索，对应原文第三段第一句，…student Ronan Hiekey digitised and analyzed a total of 1,882 whistles from the Irish dolphins and those from the welsh dolphins…可知Ronan Hickey不是分析宽吻海豚，而是爱尔兰海豚和威尔士海豚发出的近2000种不同的啸声(不是方言)。所以，本题选项B是答案。

第2题：

As early as the 6th century, Irish fishermen started raising dolphins in the Shannon estuary.

A．Right

B．Wrong

C．Not mentioned


正确答案：B
解析：问题中的关键词是raise，利用信息结构as early as the 6th century和特征结构Irish fishermen及Shannon estuary共同作为答案线索，对应原文第七段．References in local legend indicate there have been dolphins in the Shannon estuary for generations and they may even have been resident there as far back as the 6th century．原文中指出早在公元6世纪海豚就在香农河口繁衍生息，而不是早在公元6世纪渔民开始在香农河河口养殖海豚。题句的意思与之不符，所以答案是B。

A.had produced
B.had been produced
C.would be produced
D.were produced

答案：B
解析：
考查动词时态和语态。时间状语by tlle end oflast year意为“到去年为止”，可知此处应用过去完成时；又因car和produce之间是动宾关系，所以本题用过去完成被动式。故选B。

第5题：

A、which; which

B、that; which

C、that; that

D、where; that


参考答案：C

第6题：

Whistles could also be used to communicate between adult dolphins and baby dolphins.

A．Right

B．Wrong

C．Not mentioned


正确答案：A
解析：问题中的关键词是adult dolphins和baby dolphins。对应原文第四段第一句，“We are building up a catalogue of the different whistle types they use and trying to associate them with behavior. like foraging，resting，socialising and the communications of groups with calves．”说科学家正在设法将啸声与海豚的行为特性联系起来，包括海豚觅食、休息、社交和有幼崽的群体间的交流等，由此可知这也包括成年海豚与小海豚之间的联络这种行为。题句的意思与原句的意思相符，所以答案是A。

第8题：

Irish Dolphins May Have a Unique Dialect

Irish scientists monitoring dolphins living in a river estuary in the southwest of the country believe they may have developed a unique dialect to communicate with each other.

The Channel Dolphin and Wildlife Foundation (SDWF) has been studying a group of up to 120 bottle-nose dolphins in the River Shannon using vocalisations collected on a computer in a cow shed near the River Shannon.

As part of a research project, student Ronan Hickey digitised and analysed a total of 1,882 whistles from the Irish dolphins and those from the Welsh dolphins on a computer and separated them into six fundamental whistle types and 32 different categories. Of the categories, he found most were used by both sets of dolphins—but eight were only heard from the Irish dolphins.

"We are building up a catalogue of the different whistle types they use and trying to associate them with behaviour like foraging, resting, socialising and the communications of groups with calves," project leader Simon Berrow said. "Essentially we are building up what is like a dictionary of words they use or sounds they make. "

Berrow, a marine biologist, said the dolphins' clicks are used to find their way around and locate prey. The whistles are communications. "They do a whole range of other sounds like barks, groans and a kind of gunshot. " He said. "The gunshot is an intense pulse of sound. Sperm whales use it to stun their prey. "

"When I first heard it I was surprised as I thought sperm whales were the only species who used it. We can speculate the dolphins are using it for the same reason as the sperm whales. " Berrow said.

References in local legend indicate there have been dolphins in the Shannon estuary for generations and they may even have been resident there as far back as the 6th century.

They are regularly seen by passengers on the Shannon ferry and an estimated 25,000 tourists every year take special sightseeing tours on local boats to visit them.

The difference in eating habits between the bottle-nose dolphins and the sperm whales interested the SDWF scientists.

A．Right

B．Wrong

C．Not mentioned


正确答案：C
解析：问题中的关键词是eating，利用问题句中的信息词bottle-nose dolphins，sperm whales，eating habits和特征词SDWF(香农海豚与野生动物基金会)scientists共同作为答案线索，对应内容在原文第二段、第三段，原文中只提到科学家们研究了啸声，而未出现eating，或相关词food食物，feed喂食等内容，因此判断为未提及。
