A.giving out purple ink to make itself invisible to predatorsC.giving off smelly gas to try to drive predators away（2）Which of the following statements is TRUE according to the passage? A.The opossum fakes its death to avoid being targeted by predators.C.The gas released by millipede was basically harmless.（3）The species that enjoys more than one defense mechanism is ________. A.B.C.D. （1）考查細節(jié)理解。Sea Hare (海兔)部分中的“The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators.”可知，海兔身上散發(fā)出黏糊糊的紫色墨水，這種物質使得捕食者對食物不那么感興趣，從而保護自己免受捕食者的傷害。 （2）考查細節(jié)理解。Opossum (負鼠)部分中的“In order to bee ‘dead’, they don39。故選B。根據Millipedes (千足蟲)部分中的“Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers.”可知，千足蟲主要防守是蜷成一團。眼睛，并在攻擊者身上留下可怕的氣味。故選C。3．犇犇閱讀下面短文，從每題所給的A、B、C和D四個選項中，選出最佳選項。 While every dog owner knows their dogs can read their moods perfectly, scientists have always been a little doubtful. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence. Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That39。 After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that acpany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions. The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. Since the touchscreen models were all females, this confirmed what has been observed in previous studies dogs are more efficient at reading facial expressions of people that are the same gender as their owner.（1）How did the scientists conduct the experiment? leaving dogs to women who are either happy or angry. mixing the selected dogs together. rewarding only half of the dogs touching the screen showing digital pictures of women39。s Mood Research【答案】 （1）D（2）A（3）C（4）B 【解析】【分析】本文是一篇說明文，最新的實驗發(fā)現，即狗能夠識別人的面部表情的變化。根據第二段中的For their study biologist Corson Miller and his team exposed eleven selected dogs to digital images of women that were either angry or happy.可知，實驗人員通過屏幕向這些狗展示了一組女性面部表情的照片，這些表情中既有快樂的，也有憤怒的。 （2）考查詞義猜測。由此可判斷出A符合題意，故選A。根據最后一段中的......this confirmed what had been observed in previous studies―dogs are more efficient at reading facial expressions of people that are the same gender as their owner可知，狗擅長辨別與自己主人性別相同的人的表情，由此推斷，讓主人是女性的狗來辨別男性面部表情的圖片是比較困難的。 （4）考查主旨大意?，F在，有證據表明這是正確的”，接著在下文用硬實證明了這一點。故選B。4．犇犇閱讀理解 But where do these phonemes e from and why do they shift over time?

But neither can it be reduced to the purely physical, as our inability to understand or even to recognise foreign languages makes clear. The food we eat shapes our jaws, and our jaws in turn shape the sounds of our language. The ease with which we eat probably shapes our thought too, as anyone who has suffered toothache could testify. What we eat may have shaped the sounds of our language, but how we eat changes how we feel and what we use language to express. A family meal is very different from a sandwich at the office desk, even if the calorie is the same.
