Can dogs dream? If they can, what do they dream about then?
Dr Deirdre Barritt, a psychologist, believes that she has found the secret of what dogs
dream about. She thinks dogs dream about their owners. She said, "Humans dream about
the same things they're interested in by day. There's no reason to think animals are any
different. Dogs usually like their human owners, so it's possible that your dog is dreaming
of your face, your smell and of having fun with you." She even advised pet owners to give
their pets "happy daytime experiences" to make sure they have nice dreams.
Dr Barritt said that there is no way of knowing for sure what dogs see when they
dream. Research hasn't even discovered that mystery with human dreams. Her ideas are
based on(基于) the fact that dogs and some other mammals(哺乳动物) have a sleep
cycle that is similar to the human cycles. She said, "That certainly makes it the best
guess that other mammals are dreaming too." Dr Barritt also explained why dogs move
their legs as if they're "running" in their sleep. "They are probably acting out their
dreams," she said.

1. 细节理解题。定位到文章第二段，根据“Dogs usually like their human owners, so it's possible that your dog is dreaming of your face, your smell and of having fun with you.”可知，狗喜欢主人所以会梦到主人，故选A。
2. 推理判断题。根据第二段最后“She even advised pet owners to give their pets 'happy daytime experiences' to make sure they have nice dreams.”可推断出，开心的白天经历可能帮助狗拥有美好的梦境；A选项与第三段“there is no way of knowing for sure what dogs see when they dream”不符；B选项与“Research hasn't even discovered that mystery with human dreams”不符；D选项中“All mammals”与原文“dogs and some other mammals”不符，故选C。
3. 主旨大意题。文章围绕狗是否会做梦、狗可能梦到什么展开讨论，B选项“Dogs are dreaming”最贴合文章主题；A选项未提及狗喜欢做梦；C、D选项仅涉及文章部分内容，并非主旨，故选B。
4. 推理判断题。本文是关于狗做梦的科普类文章，字典（dictionary）、旅游指南（travel guide）、故事书（storybook）均不符合这类内容的载体，杂志（magazine）适合刊登此类科普文章，故选C。
