But what if we see an animal in trouble, does the same rule apply? This question was raised after a group of penguins were saved from an icy gully (峽谷) in Antarctica. It was filmed for the BBC wildlife series Dynasties. The film crew were anxious when they saw that a group of penguins had fallen into a gully and been trapped with their young. They built a slope (斜坡) so that a few of the penguins could save themselves. The case has taken the international media by storm. Viewers watching this film let out a sigh of relief. I39。m so glad. I understand not taking action directly, but a helping hand isn39。t bothering, right? viewer Kathryn Shaw said on her Facebook. However, others think human interference (干涉) is unnatural. You can39。t have sunshine throughout your life. To have done anything else would only make matters worse, said the show39。s creator David Attenborough, according to The Times. In this case, however, Mike Gunton, the executive producer of the series, said that this was a oneoff situation. There were no animals going to suffer by interfering. You weren39。t touching the animals and it was just felt by doing this... they had the chance not to have to keep slipping down the slope, he told the BBC. Such cases are familiar to Paul Nicklen, wildlife photographer for National Geographic. He told Metro, If it39。s ever a predator (捕食者) situation, no matter how gutwrenching, you stay out of the way. Even when you39。re watching a male polar bear eat a baby bear. There39。s no rule book in those situations. You can only respond to the facts that are right there in front of you, Will Lawson, the show39。s director, told Daily Mail.（1）What has led to a heated media discussion? 39。s various remarks on penguins. rescue of penguins from a gully. penguins39。 sufferings in a gully. of filming the series Dynasties.（2）Who holds a positive attitude towards human interference? Shaw. Lawson. Nieklen. Attenborough.（3）Which of the following best explains the word gutwrenching underlined in paragraph 6? one in place. one confused. one in danger. one heartbroken.（4）What can be a suitable title for the text? for the Necessity of Lending a Hand to Animals on How to Protect Animals From Danger of Human Interference on Dangerous Animals on Whether to Help Animals in Trouble or Not【答案】 （1）B（2）A（3）D（4）B 【解析】【分析】本文是一篇說明文，介紹了當動物們面臨危險時，我們是否要伸出援救之手，以及如何去保護它們脫險。 （1）考查細節(jié)理解。根據第二段中的“The film crew were anxious when they saw that a group of penguins had fallen into a gully and been trapped with their young. They built a slope（斜坡）so that a few of the penguins could save themselves.”和第三段中的“The case has taken the international media by storm”可知，從峽谷中救出企鵝這一事件引起了大家的熱議。故選B。 （2）考查推理判斷。根據第三段中的“I39。m so glad. I understand not taking action directly, but a helping hand isn39。t bothering, right? viewer Kathryn Shaw said on her Facebook.”可知，她對幫助動物是很贊成的，故選A。 （3）考查詞義猜測。根據上文大家對干涉動物的行為有不同觀點，再結合下文的“you stay out of the way. Even when you39。re watching a male polar bear eat a baby bear.可知，此句句意為：如果這是個捕食的情景，無論你是多么的心碎，你都不能干預。結合四個選項可知，此處用Making one heartbroken（心碎）最合句意。故選D。 （4）考查主旨大意。本文就救助企鵝的視頻引發(fā)的熱議講述了當動物面臨危險時，我們如何伸出援助之手給出了一些建議。因此，本文的最佳標題應為“若何保護動物脫險的建議”。故選B。 【點評】本題考點涉及細節(jié)理解，詞義猜測，推理判斷和主旨大意四個題型的考查，是一篇科教類閱讀，要求考生在捕捉細節(jié)信息的基礎上，進一步根據上下文的邏輯關系，進行分析，推理，概括和歸納，從而選出正確答案。5．犇犇閱讀理解 Acting is the least mysterious of all crafts, Marion Brando once said. But for scientists, working out what is going on in an actor39。s head has always been something of a puzzle. Now, researchers have said actors show different patterns of brain activity depending on whether they are in character or not. Dr Steven Brown, from McMaster University in Canada, said, It looks like when you are acting, you are suppressing (壓制) yourself。 almost like the character is possessing you. Brown and colleagues report how 15 actors, mainly theatre students, were trained to take on a Shakespeare role — either Romeo or Juliet — in a theatre workshop. They were then invited into the laboratory, where their brains were scanned in a series of experiments. Once inside the MRI scanner, the actors were asked to answer a number of questions, such as: would they go to the party? And would they tell their parents that they had fallen in love? Each actor was asked to respond to different questions, based on two different premises (前提). In one, they were asked for their own perspective, while in the other, they were asked to respond as though they were either Romeo or Juliet. The results revealed that the brain activity differed depending on the situation being tested. The team found that when the actors were in character, they use some thirdperson knowledge or inferences about their character. The team said they also found additional reduction in activity in two regions of the prefrontal cortex (前額皮質) linked to the sense of self, pared with when the actors were responding as themselves. However, Philip Davis, a professor at the University of Liverpool, was unimpressed by the research, saying acting is about far more than pretending to be someone — it involves embodying (體現) the text and language.（1）How did Dr Brown39。s team conduct their research? A.By scanning the brain activity of some actors.B.By doing a survey with some theatre goers.C.By interviewing some th
