The research, published by the National Academies of Science, Engineering and Medicine, said, At the current rate, the world39。 Professor David Vaughan, science director at the BAs, said, We need to be bold (大膽的) on this one. Larsen C is a long way south and there39。 s biggest iceberg in a mission aiming to answer fundamental questions about the impact of climate change in the polar regions. The scientists, led by the British Antarctic Survey (BAS), are trying to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larsen C ice shelf.To study a newly discovered ecosystem.C.Climate change in Antarctica.C.It is part of an ice shelf in the Arctic.C.The ice sheets in Greenland and Antarctica are melting at a steady rate.C. （1）考查細(xì)節(jié)理解。根據(jù)第三段中的“The calving of A68 provides us with a unique opportunity to study marine life...”可知A68冰山的形成為科學(xué)家提供了研究海洋生物的獨(dú)一無(wú)二的機(jī)會(huì)，所以Professor David Vaughan認(rèn)為科學(xué)家要果敢地抓住這次機(jī)會(huì)，故this one指的是A68冰山和它下面的生態(tài)系統(tǒng)。 （4）考查推理判斷。2．犇犇Choose the one that fits best according to the information given in the passage you have just read.

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。根據(jù)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(shí)驗(yàn)人員通過(guò)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(lè)的，也有憤怒的。由此可判斷出A符合題意，故選A。 （4）考查主旨大意。故選B。 But where do these phonemes e from and why do they shift over time? New research suggests that the apparently arbitrary distribution of some sounds around the world may be partially explained by diet. This is unexpected.

Jonathon Day, a professor of medical entomology (昆蟲(chóng)學(xué)) at the University of Florida in the US, told NBC it39。Mosquitoes are especially active in the late afternoon. While flying along, they use their sense of smell to find possible targets. They find victims (攻擊對(duì)象) by smelling the carbon dioxide (CO2) breathed out by humans and animals.
