I. Reading comprehension Section A Cloze (15,) Directions: For each blank in the following passage there are four words or phrases marked A, B. C and d. Fill in each blank with the word or phrase that best fits the context Physicists, fascinated by mathematical beauty, are failing to solve new problems. " High class physicists no longer care about physical reality-nor should they. ""Science is over Those are simplified but not entirely misleading summaries of recent books by Sabine Hassenfelder ( Lost in Math), Richard Dawid String Theory and the Scientific Method) and John Horgan The End of Science),56_. I get asked about these books and their 57 message frequently. For theoretical physicists they are bitter criticism, since they argue that today's physics has gotten itself into a 58 But they disagree in their descriptions of the problem. Ms. Hassenfelder argues that physicists need to pay more attention to reality, Mr. Dawid that they can safely ignore it. Mr Horgan, 59, thinks that physicists'time is past and they should do something else instead What's going on here? Opinions may differ about the current health of physics, but no reasonable person can 60 that it has been a hugely successful enterprise. Without revolutionary 20th-century breakthroughs in quantum physics(量子物理学) and relativity(相对论), modem technology ncluding GPS, nuclear power and much more -would be literally 61 In the latter part of the 20th century our theoretical understanding reached a very high plateau (Ie TE#i). The so-called Standard Model of particle physics offers complete and62 equations (7t) for the behavior of ordinary matter under ordinary conditions (allowing a very generous63 of the word“ ordinary”) The theoretical framework of the Standard Model was in place by the 1970s, which predicted and 64 remarkable new discoveries and observations, notably including experimental confirmation of the existence of quarks (G JE).It is a peak of human achievements But this grand success is bittersweet. In earlier times, research that added to or changed the theoretical foundations of physics also had practical uses and benefits. Toda, however, discoveries in fundamental physics are 65 to have a significant impact in engineering chemistry or biology, precisely because we already have well-tested foundations that seem more than adequate for those applications. The physical principles that empower 21 st-century technologies had all been 66 by the 1950s
