The idea of homework goes back a long way. Historians trace it to ancient Rome. Pliny the Younger, a teacher around AD 61-113, encouraged students to practice speaking at home. Homework evolved slowly over the centuries. In the U.S., it grew common in the early 20th century. In 1957, American schools piled on homework to raise academic demands. By the 1980s, it was seen as key to academic success.

For high schoolers, homework links to academic performance. But younger kids seem to gain little from traditional homework. Furthermore, students who are responsible and supported at home are most likely to complete assignments and benefit from them. For students from lower-income families who might lack internet access, homework can actually widen the achievement gap.

Then everything changed. As educators recognized the limitations of passive, one-size-fits-all tasks in encouraging genuine understanding and student engagement, traditional worksheets and reading logs gave way to project-based assignments or online lessons, clouding the line between homework and classwork. However, just assigning tasks wasn't enough.

So, what now? Keep, change, or get rid of it? It all comes down to how it's used. When it's just something to keep kids busy, it doesn't do much. But when thoughtful, clear, and actually fitting what a student needs, it has its place. In a world where information is instant, the purpose of homework needs a fresh look.

A. The concept, however, faded significantly during the Middle Ages.

B. The question of whether homework actually helps students is tricky.

C. The thing is, homework isn't automatically good or bad.

D. Furthermore, access to reliable internet became a critical factor.

E. It took on a more formal role during the Industrial Revolution.

F. Ask students what school's like, and you'll hear about tests, teachers and homework.

G. Without engagement, feedback, and support, homework lost its effectiveness.

The research process involved extracting specific polymers from common brown seaweed and modifying them to create a durable yet flexible material. Laboratory tests confirmed that the new bioplastic possesses strength comparable to traditional plastic packaging. Most significantly, when exposed to soil or seawater, it breaks down into harmless organic matter through natural microbial activity. Field experiments showed complete decomposition within four to eight weeks, leaving no microplastic residues. The production method is also energy-efficient, requiring 30% less energy than conventional plastic manufacturing.

Dr. Emily Chen, the lead researcher, expressed cautious optimism about the potential impact. "This material could revolutionize packaging industries, particularly for food and consumer goods," she stated. However, she acknowledged the challenges ahead, noting that "scaling up production while maintaining cost competitiveness with established plastics remains a significant hurdle." Several major companies have already shown interest in adopting this technology, recognizing both its environmental benefits and growing consumer demand for sustainable products. The team is now focusing on optimizing the material for various commercial applications and conducting further tests to ensure its safety and durability meet industry standards.

Traditional purifiers struggle with two critical flaws: they cannot filter particles smaller than 0.01 micron, such as certain heavy metals, and users often forget to replace filter elements. The QingShui-1 team targeted these gaps with a multi-layer composite filter made of activated carbon and ceramic. Laboratory tests confirm it removes 99.8% of heavy metals and 99.5% of bacteria, trapping particles as small as 0.001 micron.

What sets it apart is smart connectivity. Linked to a WeChat mini-program, the device sends real-time alerts when the filter element nears expiration, and users can order replacements directly through the app. This solves the long-standing problem of delayed maintenance that undermines water safety.

Installation and usability were also prioritized. Its compact size fits under most kitchen sinks, and it connects to standard faucets in 5 minutes — no professional help needed. A month-long trial with 500 families in Guangzhou and Shanghai yielded positive feedback. "I used to stress about my baby's drinking water," said Ms. Chen, a participant. "Now I check quality on my phone anytime — it's such a relief."

Mass production is scheduled for December 2025, with a price 20% lower than imported alternatives. This innovation not only enhances household water safety but also makes advanced treatment technology accessible to ordinary families, reflecting China's practical approach to solving daily life challenges.

Anika's inspiration came from witnessing her grandfather struggle with diabetes-related vision loss, a condition that could have been managed with earlier diagnosis. With limited resources, she spent over a year teaching herself machine learning and collecting thousands of public medical images to train her model. The resulting software can analyze images of a person's retina taken with a smartphone adapter and identify early signs of diseases like diabetic retinopathy with an accuracy exceeding 90%. Its low cost is a key advantage, making it potentially accessible to rural clinics in developing regions.

"My goal is not to replace doctors, but to provide a tool that helps them, especially in areas with few specialists," Anika stated. Her computer science teacher, Mr. Patel, described her as incredibly resourceful, highlighting how she solved complex problems using free online courses and collaborative coding platforms. Anika has already begun working with a non-profit organization to pilot "EyeScan AI" in several community health centers. She believes that technology should bridge healthcare gaps, and she plans to continue her studies in both computer science and public health to further this mission.

On the first morning of second grade, Jared remembered five things he didn't like about school; Jessica, lining up, maths, spelling, and reading aloud. Jared wanted to stay home, but his mom sent him anyway. He had to sit next to Jessica.

At reading time, Mrs. Thomas asked Jared to read. Reading aloud always made Jared nervous. As he picked up the book, his hands shook. Words were not clear. "He can't read," Jessica said, "I didn't call on you, did I?" asked Mrs. Thomas. "No, but I'll read." Jared made a face They were asked to stay outside the classroom for a time-out (暂停), During the period, Jessica whispered to him, "When Mom brings my kittens (小猫) to school, don't even think about touching them."

The four kittens arrived in a box covered with a piece of screen. Everyone except Jared held them. Jared had nothing to do but practice spelling. When he sharpened his pencil, he looked into the tiny box. "Don't want to touch my kittens!" Jessica shouted. "Stupid kittens," Jared said. After the second class, almost the whole class wanted to play with the kittens. Then Philip said, "Hey, where are the kittens?" The box was empty. "Oh no!" Jessica said, "Jared, did you take them?" Jared shook his head, thinking they must have pushed up the lid (盖子). "He said they were stupid." Jessica told Mrs. Thomas. "I didn't mean it" Jared's face turned red.

"Look at the radiator (散热器)!" Philip said. A Tiny gray face rose from under the radiator cover. "Kitty, kitty," Mrs. Thomas said. The face disappeared. "If we ignore them, maybe they'll come out. At least the heat isn't on." Instead of practicing spelling, Jared watched the radiator. Soon, two faces and a tiny head appeared. Alex yelled, "Kitten!" The kitten was out of sight again. Jessica cried.

For 23-year-old Zhao Xiangcai, college student in Tai'an, Shandong Province, climbing Taishan Mountain had always been a daunting task. This Spring Festival, his otherwise exhausting experience (transform) by a robotic exoskeleton device. "It felt like the robot was doing most of the work for me."

The robotic exoskeleton, weighing just 1.8 kilograms, has been developed by the Taishan Cultural Tourism Group in collaboration with Kenqing Technology, a company based in Shenzhen, Guangdong Province. It is designed    (assist) users in climbing steep terrain with ease. The device, fits snugly around a user's waist and legs, integrates advanced ergonomics, power electronics and artificial intelligence algorithms to perceive movement and provide assistance based    the terrain and the user's strides.

The robotic exoskeleton can function nonstop for more than five hours on a single charge,      (cover) approximately 14 kilometers of steep terrain, making it an (idea) companion for those who want to enjoy the bliss of mountains excessive physical strain.

According a report by the China Academy of Information and Communications Technology, humanoid robots are poised to become the next major technology platform after personal computers, smartphones and new energy vehicles,(potential) forming a trillion-yuan-level market.

In 2016, I got passed to be a foster (收养) parent. By the end of 2019, ten kids had filled my house. In 2020, I got a call from a center for8 children. When asked if I could take Anthony, I9 it because ten kids were all I could do with.10, I was talked into taking Anthony just for the weekend. I didn't ask about his situation11.

Anthony arrived that night, "Can I call you Dad?" he asked.

"No." I needed to keep my12.

Monday morning a worker in the center came to13 Anthony. From their talk, I learned he had been14 three times, but nobody would take him in.

Looking at Anthony, I saw something that made me think of the15 boy I had once been. "I'll take him in," I said.

Listen and follow up

First, remember the importance of listening. Listen to the other person attentively, so that you can ask a follow-up question. For example, let's say the other person tells you, "I just got back from a trip to Canada." Where did you go in Canada? What was your favorite place there?

How was the food there?

Avold simple "yes" or "no" questions

If you want to keep a conversation going, it's a good idea to ask questions that cannot be answered with a simple "yes" or "no". If the other person asks you a "yes" or "no" question, try to give a longer answer to help keep the conversation going.

For example, a friend might ask, "Hey, have you seen the new Star Wars movie?" You could just answer, "No, I haven't." You could answer: "No, but I plan to see it soon. How about you?"

Do not worry about your pronunciation. If your pronunciation is a little different, the other person will still understand your message if you try speaking slowly and clearly. When you are traveling in an English-speaking country and have some free time, be brave and speak in English with someone who does not look too busy.

A. Or, you could say more.

B. Be brave and practice often.

C. You can try the following ways.

D. Why did you choose the destination?

E. Then you may make a new friend.

F. Correct your pronunciation if possible.

G. You can continue with a question using where, what, why, or how.
