Rain, especially, helps plants grow and stay green. But too much rain, especially in cities, can lead to flooding. That can cause waste water systems to overflow and send pollutants into rivers and other waterways. To fight the problem, several cities in the United States are starting programs like rooftop gardens. A team at the University of the District of Columbia in the nation39。s capital has created a garden on the top of one school building. The garden holds many kinds of plants to help absorb rainwater and grow food at the same time. Architect David Bell has designed five green roofs for the university. He says he is excited about the project because it meant doing something more than just dealing with storm water management. It took advantage of a resource above the city and these flat roofs that aren39。t doing anything really became something that was about urban agriculture. Rainwater is collected in large containers and sent through a system that waters the rooftop garden. The roof is filled with green life that appeals to insects. In cities, you don39。t have that many spaces to choose from and so rooftops are just (unused) space, says Caitlin Arlotta. She is a student in the school39。s Urban Agriculture program. The project is part of a research program to see which plants do well on rooftops. The researchers are looking at plants including strawberries, tomatoes and sweet potatoes. The university also has other green spaces. We also have our own farm experiments, Arlotta said. Within each of those growing systems, we want to be able to tell people which sorts of these crops grow the best. Sandy Farber Bandier helps run UDC39。s Master Gardener program. It seeks to improve cities and make them beautiful by training people to bee Master Gardeners. She says she39。s been surprised by the garden39。s output. My biggest surprise was that we produced 4, 250 pounds of produce the first year and was able to spread that to people in need. She also likes being able to show people who live in D. C. and others beyond the nation39。s capital what and how food can be grown on a rooftop. This is the future for food. You grow it here, you prepare it in a mercial kitchen, you distribute through farmers markets, food trucks, and then you recycle.（1）What do we know about the rooftop gardens? A.Rooftop gardens are very mon in average neighborhoods.B.There are many sorts of plants there which help take in rainwater.C.They39。re playing an important role in the city39。s food supply.D.Rooftop gardens are no more than containers to collect rainwater.（2）What can we infer from Paragraph 3? A.Rooftops can offer enough space to plant crops.B.Many plants like strawberries can grow well on rooftops.C.Some university students are participating in the Urban Agriculture program.D.The plants in rooftop gardens are attractive to many insects.（3）How does Sandy Farber Bandier feel about the future of rooftop gardens? A.Confident.B.Doubtful.C.Worried.D.Ambiguous.（4）What is the best title for the text?

The researchers are looking at plants including strawberries, tomatoes and sweet potatoes. The university also has other green spaces. ‘We also have our own farm experiments’?！笨芍?，凱特琳阿洛塔是該校都市農(nóng)業(yè)計(jì)劃的學(xué)生。研究人員正在研究包括草莓、西紅柿和甘薯在內(nèi)的植物。這所大學(xué)還有其他綠地。，我們也有自己的農(nóng)場(chǎng)實(shí)驗(yàn)，由此可推斷出有許多大學(xué)生正在參與這項(xiàng)城市農(nóng)業(yè)計(jì)劃。故選C。 （3）考查推理判斷。根據(jù)最后一段中的“She also likes being able to show people who live in D. C. and others beyond the nation39。s capital what and how food can be grown on a rooftop. ‘This is the future for food. You grow it here, you prepare it in a mercial kitchen, you distribute through farmers markets, food trucks, and then you recycle. ’ Sandy Farber Bandier 喜歡向住在華盛頓特區(qū)和首都以外地區(qū)的人們展示在屋頂上可以種植什么以及如何種植食物。她認(rèn)為這是食品的未來。你在這里種植，在商業(yè)廚房里準(zhǔn)備，通過農(nóng)貿(mào)市場(chǎng)分發(fā)。食品卡車，然后回收利用。 由此可推斷出她對(duì)于屋頂花園的未來很自信。故選A。 （4）考查主旨大意。第一段說美國(guó)由于雨水過多，為了避免浪費(fèi)，美國(guó)的幾個(gè)城市正在啟動(dòng)屋頂花園等項(xiàng)目。接著下文進(jìn)行了詳細(xì)介紹了在大學(xué)校舍的頂部建造花園，種植多種植物吸收雨水，利用城市上空的一種資源，成為了城市農(nóng)業(yè)的一部分，有人認(rèn)為這是未來的食物。由此可知，本文主要敘述了綠色屋頂城市農(nóng)業(yè)的未來。綜觀全文可知，文中g(shù)reen roofs（綠色屋頂）貫穿全文，第一段最后一句green roofs（綠色屋頂）是建在城市的農(nóng)業(yè)（Urban Agriculture），故選B。 【點(diǎn)評(píng)】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，是一篇介紹類閱讀，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。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
