专题限时集训(二十五)　语法填空(Ⅳ) A (2019·郑州市质量预测) Chinese researchers have 1.successfully(successful) grown and harvested rice in the deserts of Dubai after developing a strain(品种) which 2.allows(allow) the crop to grow in salt water. A team of scientists, 3.led(lead) by China's “Father of Hybrid Rice” ， Yuan Longping, have already started growing the crop in dilute(稀释的) seawater at home and are now bringing the technique to the Middle Fast. The big harvest of rice last year in the suburbs of Dubai far exceeded scientists' expectations, according to a report by Xinhua News Agency. The high output — 7，500 kilograms per hectare compared with the 4.global(globe) average of 3, 000 kilograms per hectare — has encouraged scientists to expand the project. They 5.planned(plan) to set up a 100­hectare experimental farm in Dubai later last year. They will put it into regular use this year and then start expanding after 2020. The Dubai project is cooperation between China's Sea Rice Research and Development Center with the Private Office of Sheikh Saeed Bin Ahmed Al Maktoum. The two parties have signed an 6.agreement(agree) to promote seawater rice across the area to reduce the risk of food shortages in the future. While scientists in some countries 7.where water shortages are a serious concern have been developing desalination( 脱 盐 ) techniques to change seawater for use in agriculture, China has been working 8.to develop(develop) strains of salt­tolerant rice for the past four decades. Although 9.it is not yet clear how the Dubai project will be able to secure enough fresh water to dilute(稀释) seawater 10.for large­scale rice planting, Chinese scientists have already started growing it closer to home on a commercial scale. B (2019·沈阳市教学质量监测) Senior citizens are the first to come to our mind when we think of hearing loss, but in a recent report, hearing professionals worry teenagers will soon outnumber aging adults 11.when it comes to living with hearing loss. The rise in popularity of personal audio devices from iPods to smart phones has had dangerous effect on the ears of those who use them most — teenagers! A study 12.conducted(conduct) by the World Health Organization finds that nearly 50% of teens 13.have fallen(fall) into the habit of exposing themselves to unsafe levels of sound so far. A sound is considered unsafe when it goes beyond 85 decibels(分贝). At that level, it takes just 8 hours of listening over your lifetime to cause damage. The louder the sound is, the 14.less(little) time it takes to cause damage. Because hearing loss is 15.typically(typical) considered a health problem for the elderly, it is difficult to convince already stubborn teenagers that they 16.really(real) are doing damage to their ears. Young adults 17.who/that have been exposed to noise over a period of time may have some hearing loss symptoms. Their 18.ability(able) to learn is compromised, and they may have difficulty developing social skills. In an effort to help teens better protect their hearing, we suggest 19.setting(set) volume limits on personal audio devices. 20.It is also good to limit the amount of time exposed to noise and to take listening breaks to give the ears a rest. C (2019·合肥市质检) Some people are great at remembering faces. Once they meet you, they never forget how you look, while for other people, remembering a face is 21.simply(simple) impossible. Such people have a condition of the brain called “face blindness” ， 22.whose actual name is developmental prosopagnosia (人面失认症), or DP for short. There was a time when face blindness 23.was thought(think) to be rare. But recent 24.studies(study) have shown that it might be more common than experts had thought. The latest study on face blindness came from Duchaine, 25.a professor of psychological and brain sciences at Dartmouth College. He wanted to find out 26.whether/if the testees could recognize pictures of famous people or not. So he used fMRI to measure activities in their brains. An fMRI can identify chemical and other changes 27.resulting(result) from blood flow. Results showed that when 28.shown(show) famous faces, the testees drew a blank with them. But they could identify the actor who has one specific feature, such as his special chin or moustache. Duchaine said this study 29.itself(it) would not directly lead to any treatments. However, he said it could lead to a much 30.deeper(deep) understanding of how we remember the world around us. D (2019·太原市模拟)Birth order, whether you are an older, middle or younger child in your family, affects your career path as well as personality, a new study shows. 31．To reach(reach) their conclusions, researchers studied many successful people from different career groups. One of the most important 32.discoveries (discover) is that middle children are more likely to become CEOs than other children. Among them 33.is(be) Mark Zuckerberg. The reason could be that they are more 34.competitive(competition) and flexible to fight for attention from the parents, 35.which makes them fit for high­flying roles. 36.It is claimed that consideration of others and high levels of management are required. Interestingly, they found the 37.majority(major) of astronauts are eldest children, the 38.first(one) born children in the family. While youngest children were found to be more likely to have careers in classical music, because they are 39.possibly(possible) more sensitive and romantic. As for only children, the study suggests they are more likely to become artists due 40.to their personality of doing things perfectly and maturely.
