In the field of educational technology, some apps might be getting too smart. There are more and more apps providing help for students.
Photomath
The new, seemingly magic app allows users to take pictures of a math problem, and then receive a step-by-step solution. A Photomath spokeswoman says educators have welcomed the app with positive reviews, but the app causes a lot of angry public discussion and disagreement. Why It is because students can use it to cheat when doing their math homework.

iHomework 2
Whether you're a high school student or a college student, there's one thing you've got for sure: a lot of schoolwork. iHomework 2 can help you keep track of all your homework. It can help you arrange it in a particular order according to types, or based on deadlines (截止日期).

Long before social distancing, Greg Dailey was already keeping his customers at arm's length. In fact, to those on his paper route (路线) in central New Jersey, Greg has never been anything more than a shape past their driveway. But all that changed when one elderly customer asked him a simple favor: Could he please pull in and throw the paper closer to the garage
"If she can't get the paper at the sidewalk, which is 20 feet from the house, during the COVID-19 pandemic (流行病), how is she going to get the things she needs " Greg said. "So a couple days later I just decided, you know what, I'm going to put this note out." The note, stuck in the next day's edition, said "My name is Greg Dailey and I deliver your newspaper every morning"—which was news to most people—"I would like to offer my services—free of charge—to anyone who needs groceries."
From that moment, the phone has been ringing off the hook. He takes the orders, does the shopping, and delivers the groceries—not by throwing them out the window, but by carefully placing them on the porch.
So far, he's delivered to nearly 100 senior citizens on his route, and some not on his route. If Greg hears about a person who is elderly or disabled, he will be there. Eileen Stein, 85, said: "I don't have enough adjectives. He is one of the finest people in the world." Another went even further, and called him the closest thing to bravery and kindness.
Greg says he might not necessarily stop when the pandemic is over. "There's something about being able to do something really nice for people," Greg said. Greg didn't do volunteer work before—actually, he didn't do his own grocery shopping before. He's just a guy called on to do it by chance—who will now stay in service by choice.
4. What does the underlined part in paragraph 1 mean
A. Being familiar with his customers.
B. Being fond of his paper delivery job.
C. Trying to narrow the social distance gap.
D. Avoiding close contact with his customers.
5. Why did Greg begin the grocery delivery service
A. To earn more.
B. To make himself better known.
C. To do grocers a favor.
D. To help customers get necessities easily.
6. Which word best describes customers' attitude to Greg
A. Appreciative. B. Confused. C. Curious. D. Unconcerned.
7. What can we infer about Greg from the last paragraph
A. He will start his own grocery store.
B. He used to take part in volunteer work.
C. He developed more newspaper delivery routes.
D. He will continue his services after the pandemic.
C
After bikes and umbrellas are made sharable across China, some companies started eyeing the fitness market, so shared gym rooms have hit the streets in Beijing.
Unlike common gyms that provide large, open spaces for many members to share at the same time, the newly built shared gym rooms are small, stand-alone rooms for a person to use, often set up near living communities.
Every four-square-meter room is equipped with a treadmill (跑步机), an air cleaner, a mirror, a television and an air conditioner, and users can let down the curtains for privacy. When exercising, users can listen to music, watch movies and check emails by connecting to the Internet by the screen fixed on the treadmill. There's no shower or washbasin.
Similar to using a shared bike, users can locate a shared gym room by a smartphone application, reserve a room ahead of time and then need to scan (扫描) a QR code to unlock the door. A refundable deposit (押金) of 99 yuan is required, and users are charged 1 yuan every 5 minutes.
The shared gym rooms are created by Misspao, a Beijing-based technology company founded in July. Within several months since it was founded, the company has already raised over 100 million yuan, Yicai Global reports. The idea of the shared fitness experience is not entirely nascent. Last December, the Shanghai-based technology company VRUN set up shared treadmills in office and apartment buildings.
The sharing economy is still becoming popular in China. According to Yicai Global, confident investors are pouring millions into sharing start-ups. In March, the State Information Center published a report which predicts that the total value of China's sharing economy will see yearly growth of 40% in the coming years, and it is expected to make a great contribution to the country's GDP.
8. What makes the shared gym room special
A. Offering open spaces. B. Standing in the living zone.
C. Holding one person at a time. D. Having some advanced equipment.
9. What do people need to do to use the shared gym room
A. Book in advance. B. Pay 100yuan first.
C. Scan a QR code to register. D. Share a smartphone application.
10. What does the underlined word "nascent" in paragraph 5 mean
A. Simple. B. Popular. C. Satisfying. D. New.
11. What is the author s purpose of writing the text
A. To introduce shared gym rooms.
B. To advertise a technology company.
C. To support the shared gym rooms.
D. To promote the sharing economy.
D
The icy waters surrounding Antarctica have long been called the Southern Ocean by scientists. However, it never received the official recognition it deserved—until now. On World Oceans Day, the National Geographic Society announced that from now on, there would be five oceans: the Atlantic, the Pacific, the Indian Ocean, the Arctic Ocean, and the Southern Ocean.
The new ocean will include most of the waters around Antarctica out to 60 degrees south latitude (纬度). Unlike the other oceans, which are divided by the surrounding continents, the extent of the Southern Ocean is determined by the Antarctic Circumpolar Current (ACC)—the Earth's longest and strongest oceanic current (洋流).
The ACC encircling Antarctica and flowing from the west to the east was set 34 million years ago when Antarctica broke off from South America, which enables the water to freely flow around.
Earth's southernmost tip. Its water is colder and less salty than the ocean waters to the north and provides a unique habitat for thousands of species, including whales, penguins, and seals.
National Geographic Society's map policy committee had been considering making the change for many years. However, it is on June 8, 2021 that it recognized the Southern Ocean as the world's fifth ocean."Our maps are updated. The Southern Ocean is treated the same as the traditional four, and the next quiz question about the number of oceans has an updated official answer from National Geographic Society—five!" the officials declared.
Alex Tait, a National Geographic Society geographer, says that the change draws public attention to protecting the Southern Ocean's unique ocean ecosystem. Tait says the change will have an impact on how children using maps in school learn to see the world. "Students learn information about the ocean world through what oceans you're studying. If you don't include the Southern Ocean then you don't learn the specifics of it and how important it is," he says.
12. How is the Southern Ocean separated
A. By surrounding lands.
B. By an oceanic current.
C. By the habitat for unique species.
D. By 60 degrees south latitude.
13. What can we know about the ACC
A. It keeps flowing in circles. B. It belongs to South America.
C. It broke off from Antarctica. D. It moves freely to the north.
14. What does Alex Tait think of "the change"
A. It will attract people to ocean exploration.
B. It will contribute to the ocean protection.
C. It will help scientists research the ocean system.
D. It will make the Southern Ocean more habitable.
15. What might be the best title for the text
A. The Antarctic Waters Need Attention
B. The Earth Now Officially Has Five Oceans
C. The Feature of the Southern Ocean Is Amazing
D. The World Map Needs Updating All the Time

五、书面表达（本大题共2小题，共50.0分）
37. 最近你们学校的英语报正在征集稿件，请你以“如何安全上网”为话题写一篇稿件向其投稿。
注意：词数80左右。
38. 阅读下面短文，根据其内容写一篇60词左右的内容概要。
Human beings are smart. However, it seems that people are gradually losing their smartness as smartphones become more and more important assistants in their lives, reported a news website. As we rely too much on technology instead of our brains, many people have lost three basic abilities, said the website.
The first skill many people have lost is remembering phone numbers. Because phone numbers are stored in smartphone contact lists, there's no need to dial (拨) a number or look at it again. And some people may also have lost their sense of direction because navigation (导航) apps can guide people anywhere they want to go. These apps can even find shortest routes for you and avoid traffic jams.
However, the worst lost skills may be social ones, meaning that some people are becoming socially inept (无能的). People often bury themselves in their smartphones. As we're too addicted to what's happening online, some of us have lost conversational skills and sometimes can't even tell whether a person is happy or not. In August, researchers at the University of California, Los Angeles, studied 51 students aged 11 and 12 who had over five hours' screen time everyday. Their task was to tell the emotions of 48 pictures of faces that were happy, sad, angry or scared. The children made an average of 14.02 mistakes at the beginning. But after a five-day camp without electronic products, they made only 9.41 mistakes on average. "If you're not practicing face-to-face communication, you could be losing important social skills," concluded professor Yalda T. Uhls from the research.
Luckily, people still have a chance to get these abilities back. You should try to keep your parents' numbers in mind for emergencies. You should also pay more attention to street signs and stores, which will help you to draw a mind map and stop you from getting lost. And the easiest solution to social skill loss is to take a break from electronic equipment because we are social creatures. We need device-free time.
