Passage One Questions 46 to 50 are based on the following passage. We're eating more fish than ever these days. At around 20 kilograms per person global fish consumption is now more than twice what it was in the 1960s. What's really remarkable, though, is where that fish comes from. For the first time in human history, most of our aquatic(水产的) food now comes from farming rather than fishing. People ate around 73 million tonnes of farmed fish—just more than half of the volume of fish that humans consumed—in 2014. That's out of a total fish supply of 167 million tonnes; the remaining 20 million or so tonnes go into things like animal feed and medical products. To keep eating fish at the current rate, we're definitely going to need to keep aquaculture(水产养殖) developing. That's because the volume offish caught in the wild has leveled off since the 1990s. Back in 1974, only 10%of marine fish stocks had been overfished. Now, more than three-tenths are. Only a tenth of our oceans' fish stocks could sustain heavier fishing than current levels. But while catchings at sea have suffered, fish-farming has been growing at a fast rate. A lot of that is coming from China, which produces 60% of the world's farmed fish. In fact, some 35 countries, including China, now produce more farmed than wild-caught fish. This shift toward aquaculture isn't just good for ensuring salmon(三文鱼) on your plate; it's also crucial to ensuring food security and sustainability. By 2050, the world will need to feed an estimated 9.7 billion people. They'll have to get their protein somewhere. However, raising cattle, pigs, and other land-based animals requires vast sums of grain and water. For example, pound for pound, beef requires 15 times more feed to raise than carp, a freshwater fish farmed all over Asia. That grain-and the water needed to grow it-could be consumed by people instead. However, aquaculture is no silver bullet. In some southeast Asian countries, shrimp farming does disastrous damage to marine ecosystems. Despite these problems, however, shrimp continues to be among the most popular sea foods worldwide. 46. What does the author say is remarkable about the fish we eat?A) They reproduce quickly.B) They are mostly farmed.C) They have become as important as grain.D) They have a longer history than humans. 47. What do we need to do if we keep consuming fish at the current rate?A) Increase the fishing volume considerably.B) Develop more advanced fishing technology.C) Enlarge the marine fish stocks effectively.D) Expand the scale offish-farming continuously. 48. What does the author say about China in terms of aquatic food?A) It places increasing emphasis on fishing now.B) It boasts of the world's largest fishing stocks.C) It raises more fish than caught from the wild.D) It supplies 60%of the world's fish products. 49. Why does the author say aquaculture is so important these days?A) It is a must for feeding the world's fast-growing population.B) It proves a reliable source of protein for humans and animals.C) It is essential to maintaining both mental and physical health.D) It ensures a balanced healthy diet for people the world over. 50. What does the author imply by saying aquaculture is no silver bullet?A) Shrimp-farming is a risky business.B) Fish-farming will not be sustainable.C) Fish-farming may cause serious problems too.D) Shrimp-farming can become quite expensive.

Being short of funding and qualified teachers, schools lag behind the fast developing computer science field.[A] As computer coding has become an increasingly sought-after skill, more K-12 schools are working it into their curriculums. Some states have considered allowing students to forgo (放弃) foreign language for coding classes, despite opposition from educators.[B] There’s a debate over whether it’s appropriate to teach coding in elementary schools, with fierce opinions on each side. When it comes to allowing coding to fill foreign language requirements, though, most educators agree: Coding should be added to curriculums, but not at the expense of foreign language classes.[C] The idea is that computer programming is a language, allowing people to communicate with machines and programs. It’s the language of the 21st century and more valuable than a natural language, some advocates argue. The computer science field is growing faster than schools can keep up because of budget constraints and a lack of skills training for teachers.[D] According to the 2016 U.S. News/Raytheon STEM Index, computer science jobs have helped boost wages in the U.S., and computer-related jobs hold the top seven positions in STEM fields for highest number of workers. Foreign language interest, on the other hand, is declining for the first time since 1995. The number of higher education language enrollments declined between 2009 and 2013 by more than 111,000 spots, according to the Modern Language Association of America.[E] “I think the opportunity to give people a choice is important,” says Florida state Senator Jeremy Ring, who introduced a bill last year that would allow Florida students to choose between foreign language and coding classes for the purpose of university admissions requirements. “I think if you’re going to give two years of language in high school, you might as well do computer coding.”请选择和题干内容相一致的段落。A、[A]B、[B]C、[C]D、[D]E、[E]
