Based on the bestselling novel written by Ken Follett, this TV show starring the brilliant Eddie Redmayne is widely recognized as one of the best historical TV dramas of recent years.‎ Mahabharata This Indian Hindilanguage series is liked by many people for being regarded as the simplest and the most fun way to learn about the ageold wisdom of the Indian people.It tells us about the kings and heroes who love, fight and make wise decisions.This drama is about the endless struggle between good and evil.‎ The Crown This story about the transformation of the young Princess Elizabeth into the queen shows everything about the British monarchy (君主制)．It includes many storylines, each of which could be made into a separate TV show.The series focuses on the ageold themes of family, marriage and politics, and this is probably what makes The Crown win popularity.‎ 语篇解读：本文是一篇应用文。介绍了四部近年来比较受观众喜爱的电视剧。‎ ‎1．What do we know about Stranger Things?‎ A．Stephen King determined its style.‎ B．It consists of three children stories.‎ C．Most of its central characters are kids.‎ D．It's much more popular than Sherlock.‎ 解析：选C　细节理解题。由第一部电视剧简介中的“starring Winona Ryder and a group of amazing kids”可知，Stranger Things的主要角色大部分都是孩子。‎ ‎2．Which aspect of The Pillars of the Earth is stressed in the text?‎ A．Its background.　　　　 B．Its staff.‎ C．Its theme song.

B．Requested.‎ C．Encouraged. D．Challenged.‎ 解析：选C　词义猜测题。由第五段的内容可知，本段主要谈论了Dessi Sieburth是如何启动“护鸟”工程的，故画线词的意思为“鼓励，推动”。‎ ‎6．What will Dessi probably do next?‎ A．Write articles about birds in danger.‎ B．Help parrots losing the natural home.‎ C．Set up a website to teach how to help birds.‎ D．Recreate his own conservation organization.‎ 解析：选B　细节理解题。由第六、七段的内容可知，Dessi Sieburth接下来会致力于保护那些失去了栖息地的鹦鹉。‎ C Some pigs tend to be optimistic while others are pessimistic, according to a new research that is meaningful to animal welfare.The study, published in the journal Biology Letters, is the first to show that mood and personality interact in an animal, influencing judgment.‎ Asher, a researcher at the University of Newcastle's ‎ Institute of Neuroscience, and her team housed groups of pigs in two types of environment.One reflected standard commercial conditions and the other was cushier with more space and plenty of soft, deep straw.After the pigs got accustomed to these new homes over a few weeks, the researchers picked 18 pigs from each type to train and test their judgment.‎ ‎“To do this, we trained each pig.In one corner of a training room there would be a bowl with chocolate sweets — pigs love them — and at the opposite side of the room there would be a bowl containing coffee beans, which pigs find bittertasting，” a researcher said.‎ Over a number of training trials, pigs learned to go to the bowl reliably when it was in the corner where they had figured out to expect chocolate sweets.On the contrary, they quickly learned to avoid the bowl when it was in the corner where they would expect to find the coffee beans.‎ The researchers next placed an unfamiliar bowl in different locations, to see how the pigs would react.Some gaily dashed to the bowl no matter what was inside, showing optimism that it would contain their favorite sweets.Others, however, behaved as though they expected it to contain coffee beans, displaying pessimism.‎ The findings suggest that a onesizefitsall answer to animal welfare issues does not exist.Even if pigs are just equal to bacon or other meat for some people, there is still cause ‎ for concern.Studies have suggested that how an animal is treated during its lifetime can directly affect meat quality and taste.‎ 语篇解读：本文是一篇研究报告，讲述情绪和性格在动物中的相互作用。‎ ‎7．What was the study trying to figure out?‎ A．How to make pigs happier.‎ B．The similarities between humans and pigs.‎ C．How living environment affected pigs' mood.‎ D．How pigs' mood and personality affected their judgment.‎ 解析：选D　细节理解题。根据文章第一段第二句“The study, published in the journal ... influencing judgment.”可知，选项D正确。‎ ‎8．What does the underlined word “cushier” in Paragraph 2 mean?‎ A．Simple. B．More comfortable.‎ C．Unpractical. D．Less free.‎ 解析：选B　词义猜测题。根据画线词后的“more space and plenty of soft, deep straw”可知，另一个环境很舒适。所以选项B正确。‎ ‎9．Which bowl can test whether a pig is optimistic or pessimistic?‎ A．The bowl with chocolate sweets.‎ B．The bowl containing coffee beans.‎ C．The bowl full of both sweets and beans.‎ D．The bowl unfamiliar to two types of pigs.‎ 解析：选D　细节理解题。根据倒数第二段第一句“The researchers next placed an unfamiliar bowl in different locations, to see how the pigs would react.”以及该段后两句的对比描述可知，D选项与第五段内容一致。所以选项D正确。‎ ‎10．What do the findings of the new research imply?‎ A．People should treat pigs equally.‎ B．People's health relies on meat quality.‎ C．People should meet pigs' various needs.‎ D．People's attitude toward pigs is totally wrong.‎ 解析：选C　推理判断题。根据最后一段尤其是最后一句可推知，要想获得高质量和口感好的猪肉，人们应当满足猪的多种需要。所以选项C正确。‎
