ing kind and helpful D. finishing assigned schoolwork 27. Orpinas’ attitude towards dating in middle school is _____. A. supportive B. positive C. negative D. indifferent C Motorists who used to listen to the radio or their favorite tunes on CDs may have a new way to entertain themselves, after engineers in Japan developed a musical road surface. A team from the Hokkaido Industrial Research Institute has built a number of ―melody roads‖, which use cars as tuning forks to play music as they travel. The concept works by using grooves(凹槽 ). They are cut at very specific intervals in the road surface. The melody road uses the spaces between to create different notes. Depending on how far apart the grooves are, a car moving over them will produce a series of high or low notes, and designers are able to create a distinct tune. Paten documents for the design describe it as notches ―formed in a road surface so as to play a melody without producing simple sound or rhythm and reproduce melodylike tones.‖ There are three musical strips in central and northern Japan—one of which plays the tune of a Japanese pop song. Reports say the system was invented by Shizuo Shinoda. He scraped some markings into a road with a bulldozer before driving over them and found that they helped to produce all kinds of tones. The optimal speed for melody road is 44kph, but people say it is not always easy to get the intended sound. ―You need to keep the car windows closed to hear well,‖ wrote one Japanese blogger. ―Driving too fast will sound like playing fast forward, while driving around 12mph [20km/h] has a slowmotion effect, making you almost carsick.‖ 28. We can learn from the passage that the highness of notes is depended on _____. A. how far the grooves are B. how big the grooves are C. the number of the grooves D. the speed of the car 29. The underlined word ―optimal‖ in the passage might mean ________. A． fastest B. possible C. best D. slowest 30. In order to hear the music well, you have to ______. A. drive very fast B. drive slowly C. open the windows wide D. keep the windows closed 31. What’s the best title of the passage? A. A New Type of Music B. Melody Roads in Japan C. A Musical Road Surface D. A New Invention in Japan D Measles (麻疹 ), which once killed 450 children each year and disabled even more, was nearly wiped out in the United States 14 years ago by the universal use of the MMR vaccine (疫苗 ). But the disease is making a eback, caused by a growing antivaccine movement and misinformation that is spreading quickly. Already this year, 115 measles cases have been reported in the USA, pared with 189 for all of last year. The numbers might sound small, but they are the leading edge of a dangerous trend. When vaccination rates are very high, as they still are in the nation as a whole, everyone is protected. This is called ―herd immunity‖, which protects the people who get hurt easily, including those who can’t be vaccinated for medical reasons, babies too young to get vaccinated and people on whom the vaccine doesn’t work. But herd immunity works only when nearly the whole herd joins in. When some refuse vaccination and seek a free ride, immunity breaks down and everyone is in even bigger danger. That’s exactly what is happening in small neighborhoods around the country from Orange County, California, where 22 measles cases were reported this month, to Brooklyn, ., where a 17yearold caused an outbreak last year. The resistance to vaccine has continued for decades, and it is driven by a real but very small risk. Those who refuse to take that risk selfishly make others suffer. Making things worse are state laws that make it too easy to opt out (决定不参加 ) of what are supposed to be required vaccines for all children entering kindergarten. Seventeen states allow parents to get an exemption (豁免 ), sometimes just by signing a paper saying they personally object to a vaccine. Now, several states are moving to tighten laws by adding new regulations for opting out. But no one does enough to limit exemptions. Parents ought to be able to opt out only for limited medical or religious reasons. But personal opinions? Not good enough. Everyone enjoys the lifesaving benefits vaccines provide, but they’ll exist only as long as everyone shares in the risks. 32． The first two paragraphs suggest that ____________. A． a small number of measles ca。
