唐代是中国古典诗歌的鼎盛时期,在不到300年的时间里,产生了许多著名的诗人和诗作。时至今日,有超过5万首唐诗和2000多位唐代诗人为人们所熟知。其中,唐代最著名的诗人是李白和杜甫。李白生性无拘无束,才华横溢,他创作了大量赞美祖国大好河山的诗篇。杜甫年轻时坎坷的生活经历,使他更好地了解了社会的黑暗和人民的困苦。最流行的唐诗作品集或许是由清朝的学者孙洙编著的《唐诗三百首》(300 Tang Poems)。唐诗一直在影响着世界文学和现代诗歌。

It's a good idea to apply sunscreen before heading to the beach if you don't want to burn. But for marine animals like whales, they don't have that【C1】______Species like sperm whales can spend up to six hours at the ocean's surface in between dives,【C2】______in the sunlight. So how do they protect themselves from a serious case of sunburn? It turns out that their bodies have a similar defense【C3】______against the sun's UV radiation as people. Blue whales—which have the lightest skin color of the three species—tan during their summer stay before【C4】______, back to their northern feeding grounds. Sperm whales don't tan. They can receive an "overdose" of UV radiation during their hours at the ocean's surface, and they have proteins that【C5】______protect their cells from UV damage. This process is【C6】______to how human bodies produce antioxidants in response to molecules that can cause a lot of genetic and cellular damage. And fin whales escape sun damage thanks to their high levels of melanin—a dark substance in the skin to protect humans from UV radiation. Older whales and whales with less【C7】______of melanin in their skin—like blue whales—had the greatest level of damage in their mtDNA.

All through the ages the bat has been a creature of great mystery. Bats have influenced the imagination of the Western World since the first Spaniards returned from the Americans. They told tales of hairy, winged creatures that flew from caves to feed on the blood of man and animals. The vampire bat, which became a well-known figure in the folk tales of many countries, exists only in the Americans. The vampire bat is not like the common bat. Its teeth have grown sharper. In the days before Columbus, bat fed on wild animals, but with the introduction of farm animals into the New World by the Spaniards, they were offered a new kind of food. They attacked the cattle which sickened and died and the colonists didn't know why. It was only in 1908 that farmers in Brazil discovered that the bite of the vampire bat could cause rabies and this was the disease that was killing their cattle. For the first time it was recognized that the bite of a vampire bat could carry the virus of rabies. The cattle of eastern Mexico were especially troubled by this disease. Many efforts were made by the farmers in Mexico to destroy the bats. They blew up their caves or covered the entrances to caves with nets. All these ways were too slow, too costly, or else didn' t work. Since they could not remove the bats, the Mexican government and World Health Organization got together in 1952 to develop a cheap dependable supply of the vaccine against rabies at a factory in Mexico. A quarter of a million cattle have been vaccinated at a cost of fifty cents per animal to the owners. In one state alone, death among cattle has fallen from 56% to 1%. Control of the disease in animals seems to be in sight. This will reduce but not destroy the threat that bats may pass the disease to human beings. Vampire bats like human blood best. Whole villages in Guatemala have disappeared because of the frequency with which bats fed on sleeping children. A study made in Trinidad showed that in thirty houses checked in one village, twenty persons had been bitten by bats. Teachers reported that half of the children coming to school showed signs of having been bitten in the night. A health research office, which has been collecting information since 1949 about the home and movements of bats, has started work on a book about bats. Various other health organizations also are making new studies. It is hoped that answers to this health problem will soon be found.

尽管 电子阅读器 (e-reader)市场用户在中国基础庞大、潜力非凡,但由于中国的 电子阅读 (e-reading)趋势具有强烈的“中国特色”,外资企业对中国市场望而却步。首先,目前中国电子书市场的主要驱动力是数量庞大的手机用户。中国共有7900万电子书读者,其中6.3%通过手机阅读,仅0.3%使用 专门的 (dedicated)电子阅读设备。其次,中国消费者不愿意为电子书付费,且阅读的主要目的是娱乐。可见,不同于美国的电子书读者,中国的电子书读者并不是转投新媒介的传统购书者。

Amid all the job losses, there's one category of worker that the economic disruption has been good for nonhumans. From self-service checkout lines at the supermarket to industrial robots armed with saws and taught to carve up animal bodies in slaughter-houses, these ever-more-intelligent machines are now not just assisting workers but actually kicking them out of their jobs. Automation isn't just affecting factory workers, either. Some law firms now use artificial intelligence software to scan and read mountains of legal documents, work that previously was performed by highly-paid human lawyers. "Robots continue to have an impact on blue-collar jobs, and white-collar jobs are under attack by micro-processors," says economics professor Edward Learner. The recession permanently wiped out 2.5 million jobs. U. S. gross domestic product has climbed back to pre-recession levels, meaning we're producing as much as before, only with 6% fewer workers. To be sure, robotics are not the only job killers out there, with outsourcing(外包) stealing far more jobs than automation. Jeff Burnstein, president of the Robotics Industry Association, argues that robots actually save U. S. jobs. His logic: companies that embrace automation might use fewer workers, but that's still better than firing everyone and moving the work overseas. It's not that robots are cheaper than humans, though often they are. It's that they're better. "In some cases the quality requirements are so exacting that even if you wanted to have a human do the job, you couldn't," Burnstein says. Same goes for surgeons, who're using robotic systems to perform an ever-growing list of operations—not because the machines save money but because , thanks to the greater precision of robots, the patients recover in less time and have fewer complications, says Dr. Myriam Curet. Surgeons may survive the robot invasion, but others at the hospital might not be so lucky, as iRobot, maker of the Roomba, a robot vacuum cleaner, has been showing off Ava, which could be used as a messenger in a hospital. And once you're home, recovering, Ava could let you talk to your doctor, so there's no need to send someone to your house. That "mobile telepresence" could be useful at the office. If you're away on a trip, you can still attend a meeting. Just connect via videoconferencing software, so your face appears on Ava's screen. Is any job safe? I was hoping to say "journalist", but researchers are already developing software that can gather facts and write a news story. Which means that a few years from now, a robot could be writing this column. And who will read it? Well, there might be a lot of us hanging around with lots of free time on our hands.
