单选题. Veterinarians from the University of Melbourne are investigating whether kangaroos that appear to be "drunken" and "staggering" in central Victoria have suffered neurological damage because of a common pasture crop. Wildlife rescuers have reported a spike in the number of eastern grey kangaroos that appear to have Phalaris "staggers", a condition commonly seen in ruminants such as sheep and cattle that have been grazing on the new shoots of Phalaris grasses, particularly Phalaris aquatica. "A kangaroo with full blown toxicity is just horrible," Manfred Zabinskas from Five Freedoms Animal Rescue told Guardian Australia. "Their head flies around like they have got a broken neck; they summersault: they crash into fences and trees.., they look like they are drunk." Phalaris, also known as canary grass, is a tall perennial grass with large seed heads that was introduced to southeastern Australia as a pasture crop and has historically been popular among farmers because it is drought tolerant, able to cope with salinity, and has an extensive root system that can be used to stabilise gullies and water courses. But some farmers have moved away from the species because it causes Phalaris toxicity, or staggers, a condition that can cause abrupt heart failure or a slower neurological decline in ruminants, particularly sheep. In domestic animals, the condition can be managed by introducing copper into their diet and moving them away from Phalaris on to a different food source. But in wild animals such as kangaroos, the condition is believed to be irreversible. "The kindest thing to do is to euthanise them," Zabinskas said. There is very little research into Phalaris toxicity in kangaroos. A study published in the Australian Veterinary Journal in 2014 examined the brain and spinal column of seven kangaroos that had died after showing symptoms of the condition and found evidence of a "greenish discolouration" of the grey matter, consistent with signs of Phalaris toxicity in ruminants. Zabinskas said there had been a marked increase in the number of kangaroos with apparent Phalaris toxicity this year, possibly because of a greater than usual abundance of the crop. Phalaris is found along roadways, in paddocks, in public reserves, and on the fringe of Melbourne around Craigieburn and Epping. "You see some areas that are hectare after hectare of 100% Phalaris growth," Zabinskas said. Karen Macartney, from the Wildlife Rescue and Information Network, said she was called to euthanise a kangaroo on Thursday, which had been attacked by a dog because it was unable to run away. "They get to the stage where they are just helpless and they are open to any dog or fox or carnivore that comes along and has a bite," she said. Wildlife carers are trying to raise the profile of the issue with the department of environment, land, water and planning in Victoria and have asked anyone who sees a kangaroo exhibiting signs of Phalaris toxicity to report it to the department first, before calling a volunteer wildlife agency.6. A kangaroo intoxicated by Phalaris may NOT ______.

问答题.Tax universities? The unthinkable is now a live possibility. Congressional plans to tax the endowments of wealthy private schools and the tuition benefits of graduate students have elicited outrage from universities. Missing in this outcry is a recognition of the long history of reciprocity between academia and government that has incalculably benefited society. The nation's founders nourished great aspirations for higher learning. John Adams and Thomas Jefferson were so desperate to do this th
问答题1. Have you ever wondered what it would be like if machines could think? A few decades ago, such an idea may have belonged to the realms of science fiction, but nowadays it's not so far-fetched. As something of a tech junkie myself, I follow the latest advancements in artificial intelligence with great interest. AlphaGo is what is known as a "weak AI", operating within a predefined range with no self-awareness. Humans have yet to develop anything close to full artificial intelligence. Some scie

问答题1. We travel more eagerly than ever, but fewer of us end up seeing things with our own eyes. Take yourself to any place of beauty, or any event that draws a crowd. Look around and you'll see a solemn-faced, dull eyed crowd with one arm collectively raised in religious devotion. Each hand clutches a phone and each phone functions as camera. People are focused intently upon their phone screens: even when only meters away, they fail to see with their own eyes. We do sometimes benefit from the film

问答题1. News report: China has made new advancements in autonomous cars and subway trains. Baidu obtained a license to test its autonomous cars on open roads in Beijing, and a new metro line with self-driving trains is expected to begin test runs at the end of March in Shanghai. Fully autonomous driving technologies might be unlikely to arrive in the near future, but partially self-driving capabilities are expected to be applied soon in sectors using commercial vehicles. A US management consulting firm anticipates a more aggressive realization of autonomous driving around the world in the coming decade, with about 12 million self-driving vehicles in use, mainly scattered across China, Europe and the US. Topic: Are We Ready for Self-driving Cars? Questions for references: 1. Do you think that autonomous vehicles or self-piloting cars are safe enough on public roads? Why or why not? 2. What is the significance of autonomous driving technologies? How do they contribute to the realization of the Chinese Dream? 3. It is noted that automated technologies will apply artificial intelligence to correct and rectify human errors. Can AI outperform human drivers in this respect?

问答题1. We felt no need to question our forecasts, moderate them, or equivocate. Nonetheless, the evidence that we could not forecast success accurately was relentlessly overwhelming. Every few months we had a feedback session in which we learned how the cadets were doing at the officer-training school and could compare our assessments against the opinions of commanders who had been monitoring them. The story was always the same: our ability to predict performance was negligible. Our forecasts were b
问答题1. News report: Zhejiang University has recently issued a document that overthrows the widely accepted principle of academic evaluation. The new practice is this: instead of core journals, if individuals have their academic essays published in influential magazines or WeChat public accounts, such as People's Daily and other state-level media outlets, and get more than 100,000 hits for an essay, this will be seen as tantamount to an essay published in a core journal and as an important reference for academic evaluations. Soon after the announcement, the whole academia became split: some believe it is an innovation, while others argue that this new practice will damage the solemnity of academic essays. Topic: Should Online Essays Be Used in Academic Evaluations? Questions for reference: 1. What do you think of Zhejiang University's new practice of measuring and evaluating academic qualifications and achievements? 2. How should we evaluate more objectively the academic qualifications and achievements of scientists, researchers, technologists and college teachers? 3. Should we use online essays as a major channel in academic evaluations? What are the possible advantages and/or possible disadvantages in such evaluations?

Employees should instead focus on demonstrating how creatively they are trying to solve the customer's problem—that is what dr
