How has technology made your life easier? When you go to a shopping mall, you can    16    free Wi-Fi there． When you want to take a taxi, you can book one with your phone． In fact, all of these things can be seen as the first building blocks of a smart city．

The    17    of a smart city was first suggested by tech company IBM in 2010． Generally, a smart city is a city     18     uses digital (电子的) technology, such as 5G network s and the “internet of things”, to improve urban planning, save money and resources (资源), and make our lives more convenient．

Cities    19    Boston, Amsterdam and Copenhagen are already using smart technology to improve public services． In the US cities of Boston and Baltimore, smart rubbish bins (桶) can sense how    20    they are and tell workers when they need to be cleaned． In Amsterdam, traffic is monitored (监测) and adjusted according to real-time data gathered from sensors around the city． There are    21    traffic jams．

Smart cities will allow us to    22    resources． By using sensors and 5G networks to check the usage of water, gas and electricity, city managers can make sure how to use these resources more efficiently． For example, water and gas pipes (管道) could    23    repair workers when there is a leak (泄漏)． Air pollution could be more closely monitored, too．

Of course,    24    will take time to build the smart cities of the future． But since we’ve already seen successful examples, it won’t be long    25    more cities join in． Tech Republic estimates (估计) that by 2050, about 60 percent of people worldwide will live in smart cities．

21．A．less                 B．fewer                     C．busier                     D．heavier

22．A．use                 B．save                       C．invent                    D．discover

三、阅读理解（共15小题；每小题1分，满分15分）

阅读下列材料，从每题所给四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。

A

#1: Rocket mail

In 1959, the US Postmaster General, Arthur Summerfield, predicted (预言) that guided missiles (导弹) would become the usual method for sending mail before a human reached the moon． We have email now, but still no rocket mail． #2: Ape workers

Who needs robots when you could have monkeys? Glenn T． Seaborg, a Nobel prize-winning chemist, predicted in 1951 that by 2020, we’d keep apes that could drive cars and perform other tasks for us． #3: Nuclear (核) vacuums (真空吸尘器)

In 1955, Alex Lewyt, the president of a vacuum cleaner company, predicted that within 10 years nuclear power would run vacuums． What did he think people would do with the nuclear waste? #4: Meals in a pill

In 1894, the chemist Marcellin Berthelot predicted that people of the future would get all the nutrition (营养) they needed in pill form． “Wheat fields are to disappear from the face of the Earth, because flour will no longer be produced from growing wheat, but made, ” he said． While we still rely on farms for food, scientists have worked out how to make meat from plants and how to grow it from cells． #5: Virtual reality everywhere

In 1999, the futurist Ray Kurzweil predicted that by 2019, we’d wear lenses or glasses that would project (投射) virtual images onto the real world． He also thought the glasses might display a complete virtual reality that we could touch and interact with． Virtual reality (VR) technology isn’t nearly this good yet． To be fair, Kurzweil correctly predicted that AI would beat humans at chess and that we’d switch to digital books and music and movies． So maybe realistic VR is just around the corner?

A U． S． -French satellite has been sent up with a mission to map all the world’s oceans, lakes, rivers and other waterways． It’s called SWOT (Surface Water and Ocean Topography)．

It went into space on Friday, Dec． 16, 2022． Scientists hope data from the satellite will help them to watch how climate change is adversely (不利地) changing water levels． The U． S． broadcaster PBS said, “The satellite is needed more than ever, as climate change brings worse droughts, flooding and coastal erosion (腐蚀)．” A NASA spokesperson spoke of the mission’s importance． She said, “It’s a pivotal moment． We’re going to see Earth’s water like we’ve never seen it before．”

The SWOT satellite is only about the size of an SUV car． It took 20 years to develop, at a cost of $1．2 billion． High-precision radar (雷达) equipment will measure the height of water on over 90 per cent of Earth’s surface． It will survey millions of lakes, as well as 2．1 million kilometers of rivers． Scientists will find potential (潜在的) areas of water loss that could influence local populations and coastlines． NASA said SWOT is a great upgrade (升级)． A spokesperson said, “SWOT will give us a 10-fold improvement in the accuracy (精准度) of our measurements of water height．” It will help scientists to better understand “the critical role the oceans play in climate change”．

32．What’s SWOT?

A．A broadcaster．                                  B．A mission．            C．A satellite．      D．A waterway．

33．What does the underlined word “pivotal” mean in Paragraph 2?

①After winning the bid to host the 2022 Winter Olympics, China has been trying hard to hold a high-tech Winter Games． Now, as the Games are coming nearer, viewers can learn how innovative technologies are being used, especially in building venues(体育比赛场馆)．

②For example, how the National Aquatics Center, also known as the “Water Cube(立方)”, was turned into the “Ice Cube”． The “Water Cube” was built to host aquatic(水上运动的) events for the Beijing 2008 Summer Olympic Games． Now, the stadium will also host the curling(冰壶) events for the Beijing 2022 Winter Games．

③The main change is to turn the swimming pool into a four-lane curling rink(冰场)． According to Xinhua, the transformation(转变) will be completed by using a quick-disassembly(快速拆卸) system． Simply put, the water will be drained(抽干) from the pool and then a convertible frame(可移动的支架) will be built and put inside． The frame is made up of 2,600 H-shaped steel columns(钢柱) and has a height of three meters and a length of two meters, China News Service reported．

④Such transformation is an example of China’s mission(使命) to hold a “Green Games” by using sustainable(可持续的) technology for its Olympics venues．

⑤Another major technology can be seen at the National Speed Skating Oval(NSSO)． The stadium is also known as the “Ice Ribbon(丝带)”． It is the only newly-built ice spots venue for the Games．

⑥Traditionally, freon(氟利昂), which is harmful to the environment, was used in the ice-making process． But NSSO uses an environmentally friendly technology which uses carbon dioxide(CO₂) to make ice． For “Ice Ribbon” with an ice surface area of 12,000 square meters, the effect of using the new technology in reducing carbon emissions(排放) is the same as planting over 1．2 million trees, People’s Daily reported． The new technology will also be used in other stadiums including the Capital Indoor Stadium and Wukesong Sports Center．

⑦“We sincerely wish that all athletes can achieve good results at the high-tech venues during the Games,” Yu Hong, head of the technical department of the Beijing 2022 Organizing Committee, told Xinhua．

36．How many stadiums are mentioned in this article?

A．Two．             B．Three．                 C．Four．                   D．Five．

37．The underlined word “innovative” in Paragraph 1 means ________．

A．革新的            B．流行的                  C．想象的                   D．科幻的

38．What event was probably held in “Water Cube” in 2008?

A．Table tennis．  B．Diving．                C．Curling．               D．Volleyball．

39．According to Paragraph 6, carbon dioxide is used in the ice-making process instead of freon because ________．

A．it is harmful to the environment            B．it helps plant 1．2 million trees

C．it reduces carbon emission                    D．it is also used in other ice stadiums

参考答案

1． B

【详解】句意：不要害怕改变，因为它会带你走向一个新的开始。考查连词辨析。if如果；because因为；though尽管；unless除非。根据“it’s leading you to a new beginning”可知后句是“不要害怕改变”的原因，应用because引导原因状语从句。故选B。

2． C

【详解】句意：我要给我妈妈一些特别的生日礼物。我想让她开心。考查代词辨析和定语后置。something某事，多用于肯定句中；anything任何事，多用于否定句或疑问句中；nothing没有什么，多用于否定句中。根据语境可知，此处是肯定句，用something，形容词修饰复合不定代词时需后置。故选C。
