Passage One	20211011	动物类	Reef fish study	判断题 4 摘要填空 5 表格填空 4
文章大意	讲了reef fish从小鱼到成年鱼的进化过程，以及哪种鱼才是predator的捕食目标。珊瑚鱼的体型特征与被猎取之间的关系。例如动物的大小，动物的行走速度，视力等因素都对这个动物能否逃离被捕猎的危险有影响。有的科学提出越大越不容易被吃掉的假设：体型大是更好的( hypothesis: large better)。然后针对这种假设展开了讨论：是否体型越大就越在各方面机能更具优势。
答案	判断题 1. 现在们只注重研究动物们的逃跑速度对动物躲避天敌的重要性。False (原文：动物躲避天敌的能力包括 size， speed 等很多因素。) 2. 体积大的动物视力更好。True (原文：身强体壮的大个动物 visual development 也比较好。) 3. 珊瑚鱼在幼年阶段与成年阶段的特征都一样。False (珊瑚鱼 change dramatically and vary from individuals。) 4. 鱼的生长速度在成年阶段比幼年阶段慢。NG (原文：体型大的 individual 速度比较慢。) 摘要填空题 5. 是猎食者（predator）还是被捕者（prey）与 mouth size 有关 6. 体型 in medium size 更容易成为猎食者的对象 7. 为了吸引鱼类，在 artificial light 的帮助下，用 net 抓鱼 8. 把另外一种鱼被抓回并运送到 laboratory 有困难 9. 实验的时间与下一个 new moon 有关表格题（larvae settlement） st 10. 1st stage: larva grow in fish body 11. 2nd stage: adolescents settle in northern Sector, young fishes take place in open ocean 12. 3rd stage: *s migrate, move to places that are close to reef 13. During this migration process, there will be increasing mortality （答案仅供参考）

Passage Two	20210609 20091203	科技类	Moss Code	Headings7 判断题7
阅读原文	Morse Code A Morse code is being replaced by a new satellite-based system for sending distress calls at sea. Since 1992 countries around the world have been decommissioning their Morse equipment with similar (if less poetic) sign-offs, as the worlds shipping switches over to a new satellite- based arrangement, the Global Maritime Distress and Safety System. The final deadline for the switch-over to GMDSS is February 1 st, a date that is widely seen as the end of an era. For although dots and dashes will not die out altogether — they will, for example, continue to be used by * radio operators, spies, and some members of the armed forces — the switch to GMDSS marks the end of the last significant international use of Morse. B The code has, however, had a good history. Appropriately for a technology commonly associated with radio operators on sinking ships, the idea of Morse code is said to have occurred to Samuel Morse while he was on board a ship crossing the Atlantic. At the time Morse was a painter and occasional inventor, but when another of the ship’s passengers informed him of recent advances in electrical theory, Morse was suddenly taken with the idea of building an electric telegraph. Other inventors had been trying to do just that for the best part of a century. Morse succeeded and is now remembered as ‘the father of the telegraph’ partly thanks to his single mindedness — it was 12 years, for example, before he secured money from Congress to build his first telegraph line — but also for technical reasons. C Compared with rival electric telegraph designs, Morse’s design was very simple: it required little more than a ‘key’ (essentially, a spring-loaded switch) to send messages, a clicking ‘sounder’ to receive them, and a wire to link the two. But although Morse’s hardware was simple, there was a catch: in order to use his equipment, operators had to learn the special code of dotsand dashes. Originally, Morse had not intended to use combinations of dots and dashes to represent individual letters. His first code, sketched in his notebook during that transatlantic voyage, used dots and dashes to represent the dig its 0 to 9. Morse’s idea was that messages would consist of strings of numbers corresponding to words and phrases in a special numbered dictionary. But Morse later abandoned this scheme and, with the help of an associate, Alfred Vail, devised the Morse alphabet, which could be used to spell out messages a letter at a time in dots and dashes. At first, the need to learn this complicated-looking code made Morse’s telegraph seem impossibly tricky compared with other, more user -friendly designs. Cooke’s and Wheatstone’s telegraph, for example, use d five needles to pick out letters on a diamond-shaped grid. But although this meant that anyone could use it, it also required five wires between telegraph stations. Morse’s telegraph needed only one. D As electric telegraphy took off in the early 1850s, the Morse telegraph quickly became dominant. It was adopted as the European standard in 1851, allowing direct connections between the telegraph networks of different countries. (Britain chose not to participate, sticking with needle telegraphs for a few more years. ) By this time Morse code had been revised to allow for accents and other foreign characters, resulting in a split between American and International Morse that continues to this day. E On international submarine cables, left and right swings of a light-beam reflected from a tiny rotating mirror were used to represent dots and dashes. Meanwhile a distinct telegraphic subculture was emerging, with its own customs and vocabulary, and a hierarchy based on the speed at which operators could send and receive Morse code. First-class operators, who could send and receive at speeds of up to 45 words a minute, handled press traffic, securing the best -paid jobs in big cities. At the bottom of the pile were slow, inexperienced rural operators, many of whom worked the wires as part-timers. As their Morse code improved, however, rural operators found that their new-found skill was a passport to better pay in a city job. Telegraphers soon swelled the ranks of the emerging middle classes. Telegraphy was also deemed suitable work for women. By 1870, a third of the operators in the Western Union office in New York, the largest telegraph office in America, were female. F In a dramatic ceremony in 1871, Morse himself said goodbye to the global community of telegraphers he had brought into being. By the time of his death in 1872, the world was well and truly wired: more than 650, 000 miles of telegraph line and 30, 000 miles of submarine cable were throbbing with Morse code; and 20, 000towns and villages were connected to the global network. Just as the Internet is today often called an ‘information superhighway’, the telegraph was described in its day as an ‘instantaneous highway of thought’. G But by the 1890s the Morse telegraph’s heyday as a cutting -edge technology was coming to an end, with the invention of the telephone and the rise of automatic telegraphs, precursors of the teleprinter, neither of which required specialist skills to operate. Morse code, however, was about to be given a new lease of life thanks to another new technology: wireless. Following the invention of radiotelegraphy by Guglielmo Marconi in 1896, its potential for use at sea quickly became apparent. For the first time, ships could communicate with each other, and with the shore, whatever the weather and even when out of visual range. In 1897 Marconi successfully sent Morse code messages between a shore station and an Italian warship 19km (12 miles) away. The first sea rescue after a distress call sent by radiotelegraph took place in 1899, when a lightship in the Dover Straits reported the grounding of Elbe, a steamship.
