It became easier for them to make the labiodental consonants instead of purely labial (唇音) ones: one example is that f e to take the place of p. Romans said pater but English speakers (unless they39。 Babies have an astonishing talent that adults entirely lose. By the age of one, they can recognise the significant noises around them and group them into a language. When we have lost this capacity as adults, it bees enormously difficult to distinguish between sounds that are glaringly different to a native speaker. It all sounds Greek to us. This is because the range of possible sounds that humans use to convey meaning may be as high as 2,000, but few languages use more than 100 and even then the significant noises－the phonemes (音素) of a language－each cover a range of sounds and so vague distinctions which would change the meaning of a word in other languages.第一段提出文章的主旨即“每個(gè)狗的主人都知道他們的狗狗能很好地讀懂他們的情緒，但科學(xué)家們一直有點(diǎn)懷疑。故選D。 They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the puter game That scientists had a hard time keeping them away from the touch screens after the study was pleted. （3）考查推理判斷。根據(jù)The hoatzin eats cow shit so that it is nicknamed as stink bird.D. Researchers using lobsters (2f) as model predators found that the sea blocks the lobsters receptive mechanism. In other words, the sea hare gives its attacker the equivalent of a stuffy nose so they don39。s the only bird known to digest by fermentation, like a cow. This process is what causes its smell and has earned it the nickname the stink birdt have to fax anyone a death certificate. They just lie there with their tongues hanging out with the smell of dead flesh, sometimes for hours, effectively convincing potential predators they can find a much fresher meal elsewhere. Even if they keep getting attacked, they won39。 Vultures, are street sweepers that feast on the rotting flesh of dead animals, which benefits us by ridding our highways and landscapes of animal bodies and the bacteria they might carry. When vultures feel threatened they vomit, and the smell of vomitedon dead bodies puts of most predators. Throwing up allows the vulture to fly away more quicklyand the vomit can hurt the aggressor39。故選C。Many creatures living in deep water will die out due to climate change.D.The A68 iceberg with the ecosystem beneath it.D. There is growing concern about the possible impact of climate change in the Antarctic. Earlier this month, a report revealed that melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of the sea level rise. The research, published by the National Academies of Science, Engineering and Medicine, said, At the current rate, the world39。s biggest iceberg in a mission aiming to answer fundamental questions about the impact of climate change in the polar regions.

Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence. 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。由此可判斷出A符合題意，故選A。故選B。 But where do these phonemes e from and why do they shift over time?
