2021-2021-1湘一青竹湖英语九上第一次月考试卷II.知识运用第一节语法填空1.—Do you know an old man got hurt in a traffic accident yesterday—Yes. Mary and I noticed ________ lying on the ground on ________ way to school.A. him; ourB. his; herC. he; us【答案】A【解析】【详解】句意：——你知道昨天有个老人在交通事故中受伤了吗——是的，玛丽和我在我们去学校的路上，注意到他正躺在地上。
考查人称代词和形容词性物主代词。
him他；our我们的；his他的；her她，她的；he他；us我们。
根据答句中noticed和lying可知，此处是notice sb. doing，表示“注意到某人正在做某事”，notice是动词，所以此处用人称代词宾格形式，故排除B项；根据问句中“an old man”，可知此处使用人称代词him代替an old man，所以第一空使用him；根据答句中on和way可知，此处是on one’s way to sp.，表示“在某人去某地的路上”，way是名词，因此第二空应使用形容词性物主代词，句中Mary and I是两个人，为复数形式，所以第二空使用形容词性物主代词our。
故选A。
2.—How soon will Halloween come— ________ one month. There will be a special program ________ the morning of October 31st.A. For; inB. After; inC. In; on【答案】C【解析】【详解】句意：——万圣节什么时候到——一个月后，10月31日早上会有一个特别节目。
考查特殊疑问句和介词辨析。

As soon as I opened up the bill, I 13 it was actually a $5 bill. However, we had to pay 6 dollars.I could have gone inside the store to get more money from the ATM (自动柜员机), but I honestly wasn’t comfortable going inside alone because it was too 14 and not safe enough, so my mom told me to just 15 my cousin’s sweet potatoes.I told the man I didn’t have enough money, so I would leave the sweet potatoes and give him the $5. As I put the sweet potatoes down, my mom and I were about to start walking to the car. A young guy next to us, waiting to get his order, offered to 16 them. He said, “Hey, take the 17 . I’ll get them.” I honestly thought to 18 I shouldn’t do that, but he insisted (坚持) doing so. Finally, we said “Thank you” and left.It may have “just” been a dollar short, but still, he did not have to do that and it was like his first instinct (本能) as soon as he saw me put the sweet potatoes down. My mom and I were so 19 . Thanks to that man, my cousin was moved, too.Sometimes, being kind doesn’t mean doing big things.

The idea of “Pure Skies” has been created by PriestmanGoode, a British company, who wants to find a way taking in personal space and touch-free journeys.So, what could new cabins look like?For a start, there would be no more touch screens for passengers to watch movies or play games. That doesn’t mean they won’t be able to do so. Instead, there will be screens which passengers can connect their phones or iPads with, and they can control from here. Besides, safety information will be written on the back of the seat, so passengers can read those all important rules without having to touch the safety card at all.As for the seat pockets? We already know those sometimes are pretty dirty. So in the POST-COVID-19 world, you wouldn’t have a seat pocket at all. But there will be a removable (可移动的) bag for you to put some little things together.The way the seats are put could also look different. PriestmanGoode advises that the rows (排) of seats should be staggered (错开的) so that people have more personal space. This also allows people to sit with a group of two or three friends or family members, while staying away from strangers on the plane. Between each row of seats, there would be a screen from the ceiling (天花板) to the top of the seat for further protection.At the moment the “Pure Skies” cabin is just an idea, but it offers a look at what flying could look like in the future.26．The idea of “Pure Skies” _______.A．comes from PriestmanGoode, a US companyB．may make it possible to take in personal spaceC．will change the world of travel completely27．The underlined word “touch-free” in the passage means “_______” in Chinese.A．不感动的B．无接触的C．免费触摸的28．Passengers can read safety information _______.A．on the back of the seatB．in the seat pocketsC．from the middle of the ceiling29．Which is NOT right in the passage?A．Putting a screen between each row of seats is to further protect passengers. B．Passengers can watch movies on screens by controlling from their phones or iPads. C．The staggered seats allow people to sit with strangers as well as their friends.30．This article is mainly about _______.A．how to make more personal spaceB．why a company has created the new cabinC．what flying could look like post COVID-19Today almost everyone has a smart phone. So street phone booths (亭) are out of date and seem to be useless. But cities like Shanghai are trying to bring the old phone booths to life.Shanghai will make changes to 263 phone booths in Xuhui District. The Library Booth is one of the six new kinds of booths, offering 60 booths for people to borrow and read. Another kind allows users to listen to audiobooks (有声书) and even record their own voices.Shanghai is not the only city trying to save the old phone booths. London cares about them even more, because the red booths have long been a special scene in London since the 1930s when they were painted all red. In recent years, London has come up with many ideas to help phone booths stay useful. The UK company British Telecom has added screens and free WiFito some booths. Users can use them to surf online and search for maps and weather reports. The company also allows people to rent (租) some booths to change them as they want to. Since 2009, more than 1,500 phone booths have been turned into flower shops, mini-cafes, art museums and even shower rooms.In New York City, three phone booths in Time Square are turned into places for immigrant (移民) voices. When visitors pick up the phone, they can listen to oral histories of immigration from the newest New Yorkers. They can also open the books inside the booth to know more about the storytellers. Or they can share a part of their own stories if they wish.Brazil made phone booths works of art. Sao Paulo paired 100 artists with 100 phone booths. Some artists painted on the booths, and others made them sculptures (雕塑) — one was shaped like a brain and another wore a pair of shoes.Phone booths are finding creative ways to live on. Will they succeed? Only time will tell. 31．Street phone booths are out of date and seem to be useless because _______.A．the street phone booths are very oldB．smart phones are widely used in daily lifeC．there is no WiFi and screens in the booths32．London tried harder than Shanghai to keep the phone booths useful in the following ways EXCEPT _______.A．providing screens and free WiFiB．turning the old phone booths into six new kinds of boothsC．giving people a chance to change old phone booths for other uses33．For the special use of phone booths in New York, visitors CAN’T _______.A．share their own stories if they wishB．read books inside the booth about Time SquareC．listen to oral histories from the newest New Yorkers34．Brazil made phone booths artworks by _______.A．changing them into sculpturesB．making one booth look like a pair of shoesC．pairing 100 artists with 100 phone booths35．What can we learn from the passage?A．Phone booths will be sure to succeed living on in the near future.B．Different cities may use different ways to bring phone booths back to life.C．Some visitors in New York City may be glad to share their own stories in the Library Booth.四、补全短文5选4You spent many nights on your schoolwork.

When she went inside, she saw small children working with pots full of acid (酸).Kelley was angry. She later learned that there were over one million children working in hot, crowded and unsafe factories. The work was very dangerous. Every year tens of thousands of kids died or were seriously hurt. In 1889, Kelley knew that she had to do something. She wrote a book called Our Tolling Children. Kelley asked people not to buy things made by child workers.Kelley started giving speeches and writing reports. Within a few years, she became famous. Everyone knew her as the leader against child labor (劳动力). In 1893, Kelley fought for new law in Illinois, which said no factories could employ (雇佣) child workers under the age of fourteen. In the same year, a new job, Chief Factory Inspector, was also created, and Kelley got the job to make sure everyone followed the law.However, in Kelley’s second year as Chief Factory Inspector, something had happened. Smallpox (天花) broke out in Illinois. Lots of people died of it. Kelley knew that smallpox was passed easily from one person to another. It was even passed by clothing.When Kelley knew that sick people were still making clothes and giving the clothes to the children and people in their village, she then visited factory after factory. Whenever she saw sick workers, she made them stop working. Kelley told the factory owners to burn the clothes. Even though they were very angry, they burned thousands of dollars’ worth of clothes. Kelley’s actions saved many American children from smallpox, and she kept working for children’s rights for the rest of her life.40．What were the wonders of Amer ica’s factories when Kelley was young?__________________________________________________________________________ 41．How did Kelley make sure everyone followed the new law?__________________________________________________________________________ 42．When did Smallpox break out in Illinois?__________________________________________________________________________ 43．Why did Kelley tell factory owners to burn clothes?__________________________________________________________________________ 44．Kelley spent her whole life working for children’s rights, didn’t she?__________________________________________________________________________六、语篇翻译After 76 days of lockdown (封城), the city of Wuhan was set free on April 8.
