【正文】 time, inside a pool that contained 20 foraging boxes, only two of which housed fish — one with tags and the other without. Each seal was allowed to explore the boxes twenty separate times. In order to ensure that mammal was not depending on its memory, the fish were moved to different boxes each time. At first, there was no difference in the amount of time it took the seals to discover the tagged and untagged fish. However, after they had been in the pool a few times, they started locating the tagged fish much faster. To confirm that this indeed was the case, there searchers conducted a second experiment using two boxes — one with pieces of fish and the other with just acoustic tags. Sure enough, the seals were all attracted to the one that was sending out signals. While this experiment involved only seals, the researchers believe that other marine mammals may also be using the information to catch prey. Sadly, predators like sharks that have been tagged by scientists may be negatively affected, as pings they emit could warn their prey of their presence. Besides potentially messing up nature’s food chain, the “dinner bell” effect of the acoustic tags could also mean that the conclusions reached by previous fish studies may not be correct. Now that the secret is out, scientists will have to e up with another way to conduct their studies — one that is not detectable by the crafty marine animals. 8. What does the underlined part “the trick” in Paragraph 1 refer to? A. Tracking sea animals on a daytoday basis. B. Following the sound that fish make. C. Attaching tiny monitoring devices to sea animals. D. Looking for ways to catch fish. 9. What is implied about the ten young grey seals? A. They have acoustic tags attached to them. B. They were not born in the ocean. C. They have been trained to recognize acoustic tags. D. They have better hearing than normal seals. 10. After doing the two experiments the researchers most probably concluded that ________. A. seals can really make use of the acoustic signals to prey B. seals can be easily fooled by acoustic tags C. seals are much cleverer than most of the other sea animals D. it’s really easy for seals to find their prey 11. The researchers seem to believe that sharks tagged by scientists ________. A. may benefit from the tags B. may attract seals by mistake C. may be annoyed by the emitted pings D. may find it hard to find prey D At Dulles High school in Sugar Land, Texas, the roster(候選名單 )for Advanced Chinese begins with Jason Chao and ends with Kathy Zhang. In between es an unexpected name: Elizabeth Hoffman. Hoffman, now a 12th grader, began learning Chinese in the eighth grade, has spent a summer studying in Nanjing and plans to perfect her Mandarin next fall. When asked by her peerswhy she is learning Chinese, she responds with a question: “why aren’t you?” As China rushes toward superpower status, America’s schools and government officials are responding to Hoffman’s opinion. Earlier this year Eush Holt of New Jersey introduced legislation(立法 )calling for increased money of programs for less monly taught languages, “For reasons of economics, culture and security, we should have much better facilities(設(shè)備 )with Chinese languages and dialects,” he said. The State Department has pointed out Chinese is being a “critical language”, but the most recent data show that only 24,000 students in Grade 7 to Grade 12 study Chinese. Still, the number is growing. In Chicago public schools, enrollment in Chinese classes has skyrocketed from 5000 students in 2020 to nearly 35,000 students this year. In the Santa Clara County, California, enrollment has quadrupled during the same period. In 2020, when the College Board first introduces advancedplacement language exams in Chinese and Italian, 2,400 high school plan to offer AP Chinese10 times the number of students that plan to offer AP Italian. Much of the interest can be explained by China’s increasing petitiveness. “People are always trying to judge what languages are going to be useful for the future,” says Marty Abbot, the director of education at the National Council on the Teaching of Foreign Languages, Stephanie Wong, a student At Monta Vista High School in Cupertino, California, chose Chinese so that she could speak with her grandfather. Wong also predicted that Chinese will be important if she bees a doctor. 80 percent of people in her hometown are Asians. 12. What does the first paragraph mainly discuss? A. Dulles High School offers a Chinese course B. Elizabeth Hoffman takes the lead in learning Chinese C. Elizabeth Hoffman suggests her school offer a Chinese course D. Jason and Kathy are the top students at Dulles School 13. According to the text, Chinese is being a “critical language” because ______. A. American government has pointed it out B. Rush Holt introduced legislation calling for opening Chinese C. many students in the world choose to learn Chinese D. China rushes toward superpower status arouses America’s schools interest in Chinese. A. The fact that Chinese is being a “crit
