题目内容
【题目】 You may say that rain comes from clouds, but you can also say that rain is clouds.【1】, you should know the mechanism through which water moves from the Earth to the atmosphere and back again.
Dew point is the temperature at which water vapor begins to condense (凝结) and becomes water droplets that can fall as rain. Dew point can vary anywhere from the 30s (Fahrenheit) to, on rare occasions, the 80s.
【2】. Once the air has cooled past the “dew point", it condenses around a nucleus, which are usually tiny particles of dust, smoke or even salt that are floating in the air. Then tiny water droplets are formed.【3】. If you pay close attention to clouds in the sky, you'll see char they’re constantly shrinking and growing,
Water vapor that has formed clouds is on its way to becoming rain, bur it's not there yet. For now, the water droplets are 80 tiny that the air currents keep them in the air, just as swirling particles of dust can stay in the air.【4】.
When water droplets combine with one another, they become heavier than the uplift of the air around them. Eventually they fall down through the cloud as rain.【5】They attract more water vapor to themselves and grow quickly until they're heavy enough to fall as snow.
A.Rain cloud is formed when there is enough water in the air
B.As warm air rises with the water vapor it contains, it cools
C.If you are curious about what kind of cloud will become rain
D.Sometimes the droplets rise high enough to freeze into ice crystals.
E.The tiny water droplets that initially form are what you see as clouds
F.If you want a better understanding of why rain comes down from clouds
G.As those droplets continue to rise, they have two ways to come back to Earth
【答案】
【1】F
【2】B
【3】E
【4】G
【5】D
【解析】
本文是一篇说明文。文章介绍了雨云是怎么形成的。
【1】根据第一段的You may say that rain comes from clouds, but you can also say that rain is clouds.(你可能会说雨来自云,但你也可以说雨是云)可知,本文主要介绍雨云是怎么形成的,F项If you want a better understanding of why rain comes down from clouds (如果你想更好地理解为什么雨从云上落下)围绕这个主题,且承接下文。故选F。
【2】通读本段及空后的Once the air has cooled past the“dew point", it condenses around a nucleus, which are usually tiny particles of dust, smoke or even salt that are floating in the air. (一旦空气冷却过了“凝结点”,它就会在原子核周围凝结,而原子核通常是漂浮在空气中的灰尘、烟雾甚至盐的微粒)可知,本段主要讲述雨云的形成原因,B项叙述的是雨云形成的最初状况,选项中的it cools和has cooled相呼应,且语义As warm air rises with the water vapor it contains, it cools (当热空气与它所含的水蒸气一起上升时,它就变冷了)顺承下文。故选B。
【3】根据上句Then tiny water droplets are formed.(然后形成微小的水滴)中关键信息词form可知,此处就初步形成的水珠展开叙述。选项中的droplets和上句相吻合,且语义The tiny water droplets that initially form are what you see as clouds(最初形成的小水滴就是你看到的云)承上启下。故选E。
【4】根据下文Eventually they fall down through the cloud as rain.(最终它们以雨的形式穿过云层落下)及They attract more water vapor to themselves and grow quickly until they're heavy enough to fall as snow. (它们吸引了更多的水蒸气,并迅速成长,直到它们重到可以像雪一样落下)可知,此处讲述了两种降水形式。故G项As those droplets continue to rise, they have two ways to come back to Earth (随着这些水滴继续上升,它们有两种方式返回地球)符合语境。故选G。
【5】根据下文They attract more water vapor to themselves and grow quickly until they're heavy enough to fall as snow. (它们吸引了更多的水蒸气,并迅速成长,直到它们重到可以像雪一样落下)可知,D项Sometimes the droplets rise high enough to freeze into ice crystals. (有时水滴上升到足以冻结成冰晶)紧接其义,语义顺承。故选D。
单词复现法是七选五常用的大题技巧之一,即选项和原文中的某些词相同或互为词根词缀的形式相呼应。比如第3题,E选项中的droplets和上句Then tiny water droplets are formed.(然后形成微小的水滴)中的droplets相呼应。

China Using Mobile Apps to Follow Spread of Coronavirus
People in China are using apps on mobile phones to follow and perhaps help slow the spread of the new coronavirus, COVID-19. Some of the apps provide the latest information about areas hit by the virus, while others collect data on infected persons.
The Chinese government is working with two of the country’s largest technology companies to keep track of the disease. The two, Alibaba Group and Tencent Holdings, created color-based systems that record the health of individuals and identify carriers of the coronavirus.
In February, Alipay, a payment app operated by Alibaba, released a system that uses colored QR Codes to show the health of people in the city of Hangzhou. A QR code is a sign a smartphone can read with its camera. Once the sign is recognized, the phone takes the user directly to an internet link with information about a subject.
After completing the questionnaire, users receive a mobile phone message. It includes a color-based QR Code that relates to the health situation they described. Users with a red code are told to quarantine themselves for 14 days and continue reporting their condition by using Alibaba’s DingTalk messaging app. Users with a yellow code are told to stay in quarantine for 7 days, while those with a green code can travel freely.
Chinese state media said the Alibaba system would be deployed at train stations, along major roads and other travel checkpoints. They added that the system is also being used in some neighborhoods. People are asked to show QR Codes when entering their apartment buildings. Customers are asked to do the same before entering the local supermarket. Alipay said it was working with the government to expand the system nationwide.
Tencent, which operates China’s popular messaging app WeChat, reported the launch of a similar QR Code-based tracking system. Tencent developed the system with help from China’s National Development and Reform Council, which is currently in use in the southern city of Shenzhen. Officials said they expected it to be deployed to other parts of Guangdong province soon.
Even before the latest systems were announced, many Chinese were already using mapping and travel apps in an effort to avoid areas with coronavirus infections. One of the apps, developed by WeChat, uses official reports to identify places in the cities of Shenzhen and Guangzhou where coronavirus cases have been confirmed.
One user of the apps told Reuters she finds the maps can provide “psychological comfort.” The woman, who did not want her full name reported, said: “You can’t guarantee there won’t be fresh cases, but you can avoid an area that’s already hit.”
The technology website Abacus reported that citizens can request location data from their mobile phone carrier to show they had not been in affected areas. The report said that if requested, China’s state-owned telecommunication companies will send users a message listing all the areas they had visited within the past 14 days.
