Passage Two

　　There's an endless amount of scientific data proving that dogs can develop strong bonds with their owners. People aren't kidding when they say they love their dog or their dog loves them,(19) but were rather ignorant about the nature of the relationships that form between dogs.

　　In an effort to understand the matter further, I spoke with doctors Mark Beckhoff a researcher and former professor of animal behavior. The-doctors response to the question of whether or not dogs can fall in love like humans do was a straight “Of course!” (20) He went on to say that if love is defined as a long term commitment meaning dogs seek one another out when they’re apart, they're happy when they're reunited, they protect one another, they feed one another, they raise their children together.(20) Then, of course, dogs love each other.

　　Now our furry friends don't really experience romantic love, like in the movies, but they can form deep and lasting bands with their fellow dogs as well as humans.

　　(21) In fact, evidence shows almost dogs stay with one partner their whole lives. In actuality, love between dogs can be even more intimate than human relationships.

　　When they interact, they aren’t afraid to smell each other and will express themselves clearly and honestly, Once again, it seems we have a lot to learn from dogs.

　　Questions 19 to 21 are based on the passage you have just heard.

　　19. What does the passage say we don't know much about?

　　由but were rather ignorant about the nature of the relationships that form between dogs可知，人类对于狗的天性是知之甚少的。

　　20. What does Dr. Mark Beckhoff say about dogs?

　　由dogs love each other可知，狗之间也是相爱的。

　　21. What does the speaker say about most dogs?

　　由In fact, evidence shows almost dogs stay with one partner their whole lives几乎所有的狗一生都和一个伴侣在一起。

　　Passage Three

　　A piece of history has been found thanks to a boy tripping on a rare, 1.2-million-year-old animal fossil. In November 2016, Jude Sparks, now 10, was on an outing with his family near their New Mexico home, (22) when he tripped over what he thought was a cow bone. (23) Now, researchers at New Mexico State University preserving this discovery, which was identified as an ancient elephant-like animal. Kyle Sparks, father of Jude, said he let his son decide what to do with the fossil.

　　So Jude reached out to Peter Houde, a professor at new Mexico State University who had experience with the same type of fossil in the past. The next day Houde came out to see the fossil for himself. (24)Houde told ABC News that he was quite excited about the find. It was fortunate that the family didn't try to dig up the fossil because that could destroy the specimen; they did the right thing by calling someone who would know what to do. "It's great for the community, because now everybody can appreciate it," he added.

　　Houde and his fellow faculty members dug up the fossil in late May. (25) They hope to return to the site with geologists for an additional search as there could before fossils near the site. Jude and his family had been invited by the researchers to see the fossil being preserved at the university.

　　Questions 22 to 25 are based on the passage you have just heard.

　　22. What did the boy Jude Sparks think he had discovered?

　　由when he tripped over what he thought was a cow bone可知，视听一致，选出答案cow bone。

　　23. What are the researchers at New Mexico State University doing with the boy's discovery?

　　由Now, researchers at New Mexico State University preserving this discovery, which was identified as an ancient elephant-like animal可知新墨西哥州立大学的研究人员保存了这一发现。

　　24. What did professor Peter Houde say when interviewed by ABC News?

　　由Houde told ABC News that he was quite excited about the find. It was fortunate that the family didn't try to dig up the fossil because that could destroy the specimen可知，这家人没有试图挖掘化石，因为那样可能会毁掉标本。

　　25. What do the researchers plan to do?

　　由They hope to return to the site with geologists for an additional search as there could before fossils near the site可知，他们希望和地质学家一起回到遗址，在化石出现在遗址附近之前尽可能进行进一步的搜索。
