4 . For the past two months, Mandy Chen, a second-year student at Beijing University of Technology, has been posting photos of herself to Taobao, posing with a reusable cup, climbing stairs and switching off lights.     1     Taobao’s Al algorithm (算法) calculates that Chen’s use of a reusable cup reduced 15.7 grams of carbon emissions (排放), while her choice to take the stairs instead of the lift resulted in a reduction of 19.5 grams.     2    

After seven days of posting her photos, Chen exchanged the points for a dozen of biodegradable rubbish bags from Taobao. Everyone can get an endless supply of free trash bags if they keep going, according to Chen.     3    

Chen uses Carbon88, a platform launched last August by Alibaba Group Holding, to help the more than 800 million users on Taobao adopt a sustainable lifestyle. The platform rewards users for over 70 low-carbon behaviours.     4     It also recommends products that it considers environmentally sustainable, and gives users points for buying them.

    5     “I didn’t know that my actions could produce such carbon reduction,” Chen said, “Now I feel good for what I’m doing to make this world a tiny bit better. We as a part of society can call for more systemic changes.”

A．It encourages them to reduce their carbon footprint.

B．And her efforts to save electricity prevented 65.50 grams.

C．It’s a valuable addition to current carbon-reduction policies.

D．Carbon reduction has helped increase Chen’s environmental awareness.

E．Within minutes, she receives a dozen points from the app as a reward.

F．They range from taking public transport to shopping of second-hand items.

G．She is now saving points for something better, like snacks and water bottles.

5 . You see a shopper trip over in a busy street. Someone else can help. That’s what you tell yourself. This is the bystander effect in action — the dilution (淡化) of responsibility in the presence of others — and it has been demonstrated in many past studies.

But life is complicated and psychologists have seen exceptional circumstances. Two experiments were conducted by Marco van Bommel and his team using an online chat room for people with extreme emotional problems. Eighty-six students were logged into the forum (论坛) and shown five messages from troubled users. They were told to write a reply if they wanted, but it was entirely up to them.

Basically, participants could see their names on the screen alongside others’ names. A counter also told them if the forum was quiet, with just one other person logged in, or busy, with 30 others online. This arrangement reproduced the classic Bystander Effect-participants were less likely to post replies with more people logged in. However, when the researchers cued (提示) self-awareness by highlighting participants’ names in red on the screen, they posted more replies on a busy forum.

A second study was built on these findings, but this time self-awareness was raised by the presence, or not, of a computer web-camera. Over 100 participants took part. Although told the camera wouldn’t be used until later, those with cameras were asked to check the camera’s indicator-light during the study. The Bystander Effect was reproduced when web-cameras were absent-on busy forums participants posted fewer replies to needy users. By contrast, those cued to be self-aware by the web-cam actually wrote more replies.

Nearly any online community can benefit from the research. The ability to turn hesitant bystanders into eager helpers is a recipe for engagement and collective benefit. As in the research, simple design cues could be integrated to help online users remember they are visible to the community. For example, the size of profile images and specific on-site reminders can be used to highlight how users see themselves within the community.

1. What does the underlined word “it” in paragraph 1 refer to?

A．The hidden danger of a busy street.

B．The bystander effect in action.

C．The dilution of responsibility.

D．The presence of other people.

2. In the first study, the participants posted more replies to the troubled when

A．there were more emotional problems

B．the counter indicated the forum was quiet

C．their presence was reminded on the screen

D．more individuals were logged in the forum

3. Why is the web-camera used in the second study?

A．To encourage more replies.

B．To reproduce the bystander effect.

C．To further test participants’ mindset.

D．To better record participants’ actions.

4. What strategy can online communities learn from the research?

A．Working together to attract more users.

B．Combining designs to boost users’ memory.

C．Building more platforms for public promotion.

D．Exploring ways to change bystanders into upstanders.

6 . When delivering medications to patients, one of the most effective methods is direct injection (注射) into the bloodstream using a needle. But this can be an uncomfortable experience, especially for kids or adults with a fear of needles. While patients do have the option to take oral pills instead, drugs containing large molecules (分子) are not absorbed effectively this way.

Now, inspired by octopus suckers (章鱼吸盘), researchers from China and Switzerland have designed a needle-free alternative: a tiny, drug-filled, cup-like patch (贴片) that sticks to the inside of the cheeks. The device is easily accessible, and it can be removed at any time and the drug gets absorbed through the lining of the inner cheek, the team reports in a paper in Science Translational Medicine.

To test the design, the team 3D printed the suckers. They loaded each with the drug and stuck them inside the cheeks of three beagles, a kind of dog which has a similar inner cheek lining to humans. For comparison, they also delivered the drug to beagles via a pill. After three hours, the team found that drug blood concentrations in dogs with the patch were more than 150 times higher than in the dogs that took a tablet. They also found patches worked effectively for drugs with large molecules.

40 healthy human volunteers self-applied water-filled patches to see how well they would stay on while talking and moving their mouths. After 30 minutes, only five of the 40 patches had fallen off, which was because of improper placement. Most volunteers said they would prefer a patch over injections for daily applications.

Still, the team only tested the patch for a short time so they would need to find out what would happen if it was used repeatedly. They’d also need to determine which drugs would work with the technology: the target is large molecules, such as those used to treat obesity or osteoporosis, but they can’t be too large to fit in the cup.

1. Why do the researchers develop the patch?

A．To help patients overcome the fear of needles.

B．To enable kids to swallow tablets smoothly.

C．To offer a better way of drug delivery.

D．To guarantee the efficiency of oral pills.

2. What does the research on dogs prove?

A．It is technologically possible to 3D print the patches.

B．The cheek lining of dogs is similar to that of humans.

C．Patches fall easily with their mouth movement.

D．Drugs are absorbed better through patches than pills.

3. Which of the following can best describe the device?

A．Innovative and profitable.

B．Effective and user-friendly.

C．Affordable and accessible.

D．Flexible and long-lasting.

4. What does the last paragraph stress?

A．The related issues to be solved.

B．The risk of using patches repeatedly.

C．The way to identity large molecules.

D．The trouble of improving the technology.

7 . 3M and Discovery Education announced Sean Jiang from Gilman School as one of the top ten finalists from across the nation for the 2023 3M Young Scientist Challenge. It’s a competition that encourages students to identify an everyday problem and submit a video showing the science behind the solution he or she came up with.

14-year-old Jiang decided to help those who can’t see. Blind people had a hard time navigating (导航) objects that are medium to far range. So Jiang wanted to design something to give them a heads-up on obstacles (障碍) that may be incoming.

Jiang’s inspiration came from the powers of the hearing system. “I learned in school that bats and whales are able to use echolocation (回声定位) to help them navigate and just use their sense of hearing and I also saw on YouTube some very skilled blind people that use echolocation to help them walk,” said Jiang.

Jiang started with a virtual reality setting and then made it a reality. His creation uses a depth camera that can detect how close objects are, thus giving enough time to dodge the obstacles. When a blind is walking with the device, the sensor of the depth camera gathers the information regarding the obstacles’ position and distance. Then the AI system in it will turn the distance data into musical sound guidance. This could significantly increase the walking speed of a blind person as well as decrease the number of obstacles they hit.

Some other similar programs were alright at finding objects that were in close range, but Jiang still wanted the blind to experience the world even fuller so they were able to see stuff that was much further away than their circle of reach.

In October, the top ten finalists will compete in person in Minneapolis for the title of “America’s Top Young Scientist” and a $25, 000 prize.

1. What can we learn about Jiang from the first two paragraphs?

A．He was the champion of the 2023 3M event.

B．He invented technology to remove road obstacles.

C．He sought to assist the blind in walking smoothly.

D．He developed a new navigation app for his school.

2. Why did Jiang mention “echolocation”?

A．To show the development of technology.

B．To present the difficulties the blind face.

C．To stress the significance of hearing.

D．To explain the inspiration of his invention.

3. What does the underlined word “dodge” mean in paragraph 4?

A．Avoid.

B．Encounter.

C．Challenge.

D．Remove.

4. What is the text mainly about?

A．3M facilities intended for the blind.

B．A teen using sound to help the blind.

C．An invention to cure vision problems.

D．A competition to improve the blind’s life.
