【正文】 infection to her unborn baby during a woman39。s research team at the University of Maryland was the first to report a connection between T. gondii and suicidal behavior in 2020. He is cooperating with researchers in Denmark, Germany and Sweden to confirm and investigate the way leading to this association. The T. gondii parasite thrives in the intestines of cats, and it is spread through their waste. All warmblooded animals can bee infected through contact with it. Humans can bee infected by changing their infected cats39。t realize they39。s senior author Doctor Teodor Postolache, an associate professor of psychiatry(精神病學(xué) ) at the University of Maryland School of Medicine in the United States, said, We can39。s first and last payments C. how much his interest payments increased D. at what point the interest and principal payments were just about equal. C Women who own cats are more likely to have mental health problems and kill themselves because they can be infected by a mon parasite that can be caught from cat litter, a study has found. Researchers found women infected with the Toxoplasma gondii (T. gondii) parasite(剛地弓形蟲 ), which is spread through contact with cat waste or eating undercooked meat or unwashed vegetables, are at increased risk of attempting suicide. The study involved more than 45,000 women in Denmark. About a third of the world39。s total monthly payment was always ______. A. $ B. $100,000 C. $360 D. $151, 49. The table in the passage helps the readers see ______. A. Wayne39。s first monthly payment that is interest. So Wayne now owes $ 99, ( $100,625－ $). His February interest payment will be % of $ 99,. By the time Wayne makes his last few payments, his monthly interest payment has decreased considerably. His balance following his 359th payment is $ , and % of that is about $ , his final interest payment. What was the total amount of interest Wayne paid? Multiplying 360 months by $ equals $ 251, and subtracting $100,000(the loan amount) leaves $151,—over times what he actually borrowed! 46. This passage is mainly concerned with ______. A. Derek Wayne B. the Mauritanian Mortgage Corporation C. how interest payments on a loan change D. calculating the number of payments Wayne made 47. The monthly interest rate on Wayne39。s early payments. Imagine that on December 15 the Mauritanian Mortgage Corporation gives Wayne $100,000, and on January 15 his initial payment is due. Throughout this first month, interest accumulates on the entire $ 100,000. On a yearly interest rate of %, Wayne39。s principal payment—the amount he pays toward his actual loan—increases extremely slowly. Payment Number Total Monthly Payment Principal Portion of Payment Interest Portion of Payment Current Balance 1 $ $ $ $99, 2 $ $ $ $99, 359 $ $ $ $ 360 $ $ $ $ Let39。 A One of the main challenges facing many countries is how to maintain their identity in the face of globalization and the growing multilanguage trend. One of the main reasons for economic failure in many African countries is the fact that, with a few important exceptions, mothertongue education is not practiced in any of the independent African states. said Neville Alexander, Director of the Project for the Study of Alternative Education in South Africa at the University of Cape Town. In response to the spread of English and the increased multilanguage trends arising from immigration, many countries have introduced language laws in the last decade. In some, the use of languages other than the national language is banned in public spaces such as advertising posters. One of the first such legal provisions was the 1994 Toubon law in France, and the idea has been copied in many countries since then. Such efforts to govern language use are often considered as futile by language experts, who are well aware of the difficulty in controlling fashions in speech and know from research that language switching among bilinguals is a natural process. It is especially difficult for native speakers of English to understand the desire to maintain the purity of a language by law. Since the time of Shakespeare, English has continually absorbed foreign words into its own language. English is one of the most mixed and rapidly changing languages in the world, but that has not been a barrier to acquiring superiority and power. Another reason for the failure of many native English speakers to understand the role of the state regulation is that it has never been the AngloSaxon way of doing things. English has never had a statecontrolled authority for the language, similar, for example, to the Academic Francaise in France. The need to protect national languages is, for most western Europeans, a recent phenomenon especially the need to ensure that English does not unnecessarily take over too many fields. Public munication, education and new ways of munication promoted by technology, may be key fields to defend. 41. Neville Alexander believes that __________. A. mothertongue education is not practiced in all African countries B. globalization has resulted in the economic failure of Africa C. globalization has led to the rise of multilanguage trend D. lack of mothertongue education can lead to economic failure 42. The underlined word futile (in paragraph 2) most probably means ___________. A. workable B. practical C. useless D. unnecessary 43. Why do many Englishspeaking countries not support the language protection efforts described in the passage? A. They have a long history of taking words from other languages. B. They want their language to spread to other countries. C. They think language protection laws are ineffective. D.
