Singapore cannot afford to have large plots of land dedicated to growing crops—it is just too small．However, farming, or more precisely, urban farming, is now a buzz word here．Instead of looking at the grounds, Singapore has decided to look skyward, towards rooftops!
In 2020, Singapore announced plans to convert the roofs of nine multi-storey car-parks in public housing areas into spaces for commercially farmed vegetables and other crops．This is part of Singapore's strategy to meet the country's 30 by 30 goal, which is to produce 30% of its nutritional needs locally by 2030 up from 10% in 2020．
Several companies have taken on the task of cultivating the urban farming scene in Singapore．Citiponics has made a name for itself, building water-efficient organic “growing towers” that can be used to grow anything from butterhead lettuce (奶油生菜) to sweet basil (罗勒)．In April 2020, they opened the first commercial farm on the rooftop of a multi-storey car park and now sell their produce via their own brand at local supermarkets．Edible Garden City (EGC) has more than 200 farms across the island and works closely with restaurants to ensure sustainable supply and demand．A 460-square-meter farm run by EGC, is positioned on the rooftop of a mall to supply nearby restaurants．
Singapore is not alone in its efforts to go beyond the confines of conventional agriculture．All over the world, cities are seeking to feed their communities with local produce．At Thammasat University located just outside of Bangkok, a formerly disused rooftop has been transformed into a 7，000-square-meter space for organic farming, the largest in Asia．
Urban farming is not restricted to eatable plants such as leafy greens and vegetables．Rooftop Honey, which has over 130 hives throughout various locations in Greater Melbourne specializes in bees．The urban beekeeping operation, founded in 2010, serves two purposes: producing creamy and delicious honey for the city's residents while also allowing the bees to pollinate (授粉) flowers in the surrounding areas．
There are several benefits to have the farms so close to home．Through community gardens or access to commercial-scale farm produce, the public have an opportunity to understand how food is grown．As the produce is pesticide free, there is also comfort in knowing where the food comes from and its impact on the environment．
4．Why is the limited land resource in Singapore mentioned in the first paragraph
A．To explain benefits of urban farming．
B．To show the function of urban farming．
C．To introduce the result of urban farming．
D．To emphasize the necessity of urban farming．
5．What does the underlined word “confines” in paragraph 4 refer to
A．Strengths． B．Restrictions．
C．Principles． D．Profits．
6．What can we learn about urban farming from the text
A．Urban farming simply means growing fruit and vegetables．
B．Urban farming is a solution to farming where land is lacking．
C．Urban farming helps to increase the crop production greatly．
D．Urban farming has never been commercialized in Singapore．
7．Which can be a suitable title for the text
A．A New Plan Launched in Singapore
B．Singapore, the Birthplace of Urban Farming
C．Urban Farming, a Novel Pattern of Farming
D．Strengths and Weaknesses of Urban Farming
Ⅳ．阅读七选五
When thinking about placing a human being in space，one of the most important questions is how to design special clothing needed to protect the person from the dangers of the space environment． 1 The fierce heat of the sun can cause severe burns．The lack of the atmosphere can cause gases in the body to expand and even burst．With no oxygen to breathe，a human being will die in only a few moments． 2 So is the damage from small pieces of rocks and objects like meteoroids (流星体)．In 1933，an American flyer，Wiley Post，designed one of the first successful devices to protect a pilot at extreme heights． 3 Astronauts in the American space agency flew the first American space flights in the early 1960s．The clothing was similar to that invented by Wiley Post．
4 It lets them move，do useful tasks，and stay outside their spacecraft in comfort and safety for several hours．The spacesuit is called the shuttle extravehicular mobility unit or EMU．It was designed to endure longer and to permit more movement than earlier spacesuits．The EMU has a number of parts that an astronaut can link together by using only one hand，which makes it possible for each astronaut to select the parts that fit correctly．Nowadays，NASA scientists are also considering the kind of spacesuit that would be needed for exploration on the planet Mars． 5 The equipment may also have to protect astronauts from particles carried in the wind on Mars．And，they must be easy to repair and keep clean during a longer flight to and from the red planet．
A．Radiation from the sun is another risk in space．
B．The cold of space will freeze skin in a short time．
C．Today，astronauts wear very different protective clothing．
D．Special spacesuits have been used for exploration of Mars．
E．EMU has many parts that can be linked together by using two hands．
F．It was a large device that looked like a can surrounded the pilot's head．
G．Because of the gravity on Mars，spacesuits may have to be designed to be lighter than suits used in orbit or on the moon．

3．D [推理判断题。根据第一段可知，这场旅行的目的是帮助人们更多地了解太空旅行。故选D项。]
【语篇解读】 本文是一篇说明文。文章介绍了一种新型的农业模式——都市农业。
4．D [推理判断题。根据第一段“Singapore cannot afford to have large plots of land dedicated to growing crops—it is just too small．However, farming, or more precisely, urban farming, is now a buzz word here．Instead of looking at the grounds, Singapore has decided to look skyward, towards rooftops！(新加坡不能拥有大片的土地专门用于种植农作物——它实在是太小了。然而，农业，或者更准确地说，城市农业，现在在这里是一个流行词。新加坡不再看地面，而是决定看向天空，看向屋顶！)”可推断，提到新加坡有限的土地资源是为了强调城市农业的必要性。故选D。]
5．B [词义猜测题。根据下文“All over the world, cities are seeking to feed their communities with local produce．At Thammasat University located just outside of Bangkok, a formerly disused rooftop has been transformed into a 7，000-square-meter space for organic farming, the largest in Asia．(在世界各地，城市都在寻求用当地农产品养活社区。在泰国国立法政大学，一个以前被废弃的屋顶被改造成一个7 000 平方米的有机农业空间，这是亚洲最大的有机农业空间。)”可知，世界其他地区也在寻求城市农业空间，因此推断新加坡并不是唯一一个努力超越传统农业局限的国家。画线词与B项“限制”意思相近。故选B。]
6．B [推理判断题。根据最后一段“There are several benefits to have the farms so close to home．Through community gardens or access to commercial-scale farm produce, the public have an opportunity to understand how food is grown．As the produce is pesticide free, there is also comfort in knowing where the food comes from and its impact on the environment．(把农场建在离家这么近的地方有几个好处。通过社区花园或商业规模的农产品，公众有机会了解食物是如何种植的。由于这些产品不含农药，人们知道这些食物的来源及其对环境的影响也让人感到欣慰。)”可推断，城市农业对于解决土地缺乏是一个好的解决办法。故选B。]
7．C [标题归纳题。根据第一段的“Instead of looking at the grounds, Singapore has decided to look skyward, towards rooftops！(新加坡不再看地面，而是决定看向天空，看向屋顶！)”，第三段的“Several companies have taken on the task of cultivating the urban farming scene in Singapore．(几家公司已经承担了在新加坡培育城市农业的任务。)”以及全文内容可知，本文以新加坡的城市农业为例，介绍了一种新型的农业模式——城市农业，并分析了其好处。因此推断C项“都市农业：一种新型的农业模式”为最佳标题。故选C。]
Ⅳ．[语篇解读] 本文是一篇说明文。文章说当考虑把一个人放到太空时，最重要的问题之一是如何设计特殊的服装来保护这个人免受太空环境的危害。
1．B [第一段主要介绍了太空环境的危险因素，如空后讲的酷热、缺氧等。根据上下文语境， B项(寒冷会在短时间内冻住皮肤。)也是太空环境的一项危险因素，符合语境。]
2．A [该空仍旧是列举太空环境的危险因素，结合下一句“So is the damage from small pieces of rocks and objects like meteoroids．”可知，A项符合语境。]
3．F [根据上一句的“devices”，并结合F项中的代词It和device等信息，可以判断F项符合语境。]
4．C [该空是该段的主题句。由后文可知，该段介绍的是有关太空防护服的事情。因此C项符合语境。]
5．G [根据该空前一句的信息词“the kind of spacesuit”以及后一句的意思可知，此空也应该表示一项防护措施，因此G项符合语境。]
