【文章內(nèi)容簡介】 portant to get up and stretch periodically. Strength exercises with light weights like pushups can also help by strengthening the muscles.”特別是如果你一天中大部分時(shí)間都在做一項(xiàng)工作，那么定期起來活動(dòng)活動(dòng)就很重要了。像俯臥撐這樣的輕重量力量練習(xí)也可以幫助加強(qiáng)肌肉。可知第三段建議要定期做適量運(yùn)動(dòng)有益于脊椎。故選C。 （3）考查推理判斷。根據(jù)最后一段中的”Vitamin D can e from some foods, but it39。s also absorbed from sunlight, so it may help to do some exercises outside.“維生素D可以從一些食物中獲得，但它也可以從陽光中吸收，所以在戶外做一些運(yùn)動(dòng)也有助于維他命D的吸收?？芍谑彝庾龈┡P撐可以增加維生素D的攝入量。故選D。 （4）考查主旨大意。根據(jù)第一段中的”The spine stands at the center of your health, providing your body with structure and support. It also contains a major collection of nerves that deliver electric signals from the rest of the body to your brain. So it39。s important to take care of it.“脊柱位于健康的中心，為你的身體提供結(jié)構(gòu)和支撐。它還包含一個(gè)主要的神經(jīng)集合，將身體其他部位的電信號(hào)傳遞到你的大腦。所以照顧好它很重要。以及文章主要內(nèi)容為介紹了一些有助于脊椎健康的方法，故選C。 【點(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解，推理判斷和主旨大意三個(gè)題型的考查，是一篇健康類閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。5．閱讀理解 A study based on data gathered by a NASA sensor has revealed China and India, the world39。s two most populous countries, are primarily responsible for making the Earth greener over the past two decades. The study, published on Feb 11 in the journal Natural Sustainability, has found that since 2000 the Earth39。s green leaf area has increased by over 5 million square kilometers. That39。s an area equivalent to the total of the Amazon rainforests. China and India account for onethird of the greening, considering the general idea of land degradation (退化) in populous countries from overexploitation, said Chen Chi from Boston University, lead author of the study. The effect mainly es from ambitious treeplanting programs in China and intensive agriculture in both countries, NASA said in a statement. China is the source of a quarter of the planet39。s increase in forest area, despite having only percent of the world39。s vegetated (固定植被的)area, according to the study. Forest conservation and expansion programs account for 42 percent of the increase, and another 32 percent e from intensive agriculture of food crops, NASA said. While raising their green leaf areas, China and India have also greatly increased their food production through multiple cropping practices, where a field is replanted and crops are harvested several time each year. Production of grains, vegetable, fruits and more have increased by about 35 to 40 percent since 2000 to feed their large population, NASA said. Over the past decades, China has made great efforts to green the land. In 1978, the central government launched a nationallevel forestation projectthe Three North Shelterbelt Forest Program. By the end of 2017, the forest coverage rate among the regions in the project reached percent, pared to percent 40 years ago. In a greening project, Kubuqi Desert, seventh largest in the country, has seen onethird of its area covered by vegetation during the past three decades thanks to forestation efforts.（1）What have China and India contributed to according to NASA? A.Land greening.B.Land degradation.C.Population explosion.D.Forest conservation.（2）What can we learn about multiple cropping practices? A.They turn out to be ineffective.B.They improve the food output.C.They raise the vegetated area.D.They allow planning once annually.（3）What was the forest coverage rate in 1977? A.%.B.%.C.%.D.32%.（4）How is the passage mainly developed? A.By space.B.By listing facts.C.By parison.D.By making definition.【答案】 （1）A（2）B（3）A（4）C 【解析】【分析】本文是一篇新聞報(bào)道,介紹了美國航天局的一項(xiàng)最新研究顯示，中國和印度是全球綠化努力的領(lǐng)導(dǎo)者。 （1）考查細(xì)節(jié)理解。根據(jù)第一段中的China and India, the world39。s two most populous countries, are primarily responsible for making the Earth greener可知,美國宇航局的研究顯示中國和印度使地球變得更綠,也就是說中國和印度的主要貢獻(xiàn)在于土地綠化,故選A。 （2）考查細(xì)節(jié)理解。根據(jù)第三段中的China and India have also greatly increased their food production through multiple cropping practices,可知,中國和印度通過復(fù)種提高了糧食產(chǎn)量,故選B。 （3）考查細(xì)節(jié)理解。根據(jù)最后一段中的By the end of 2017, the forest coverage rate among the regions in the project reached percent, pared to percent 40 years ago.可知,截至2017年底,%%,%,故選A。 （4）考查推理判斷。根據(jù)第二段中的That39。s an area equivalent to the total of the Amazon rainforests.,第三段中的China is the source of a quarter of the planet39。s increase in forest area, despite having only percent of the world39。s vegetated (固定植被的)area,及第四段中的By the end of 2017, the forest coverage rate among the regions in the project reached percent, pared to percent 40 years ago.等信息可知,文中多次用數(shù)據(jù)對過去和現(xiàn)在進(jìn)行對比來顯示中國和印度是全球綠化努力的領(lǐng)導(dǎo)者的,因此文章是通過對比的手法展開的,故選C。 【點(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解和推理判斷兩個(gè)題型的考查，是一篇新聞報(bào)道，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。6．閱讀理解 Loud cheers and applause broke out at NASA39。s Jet Propulsion Lab on Monday, November 25, 2018, as the unmanned lander, called Insight, touched down on Mars, after nearly seven years from design to launch to landing. The great arrival of the spacecraft173。designed to listen for quakes and shakes as a way to discover the Red Planet39。s inner secrets, how it formed billions of years ago and, how other planets like Earth took shape173。marked the eighth successful landing on Mars in Nasa39。s history. Minutes after InSight landed on the surface of Mars, the first image was sent back, showing a wide flat area as seen through a dirty camera. The touchdown came after a nearly sevenmonth, 300 millionmile travel from Earth to Mars, during which the InSight spacecraft had to slow down from a speed of more than 12,000 mph. The spacecraft39。s heat shelter helped the lander survive temperatures as high as
