When it comes to protecting and dispensing (分发) food, the right package can greatly reduce waste. Here are a few examples.

Packaging keeps the meat fresh.

We throw away a fifth of the beef we buy — the equivalent (等量) of 8 million cows each year — often because it goes bad before we cook it. The solution? Case-ready packaging can lengthen that shelf life to up to 21 days. If the meat you bought isn't going to be eaten within a few days, case-ready packaging is the better choice for the environment.

This dairy waste can be avoided with packaging technology such as Tetra Pak (利乐包装纸盒), which is commonly used in Europe and Asia to keep milk from spoiling, even without refrigeration. Recycled or not, Tetra Pak is a good environmental bet because it can lengthen the shelf life of milk up to nine months. Once again, the environmental benefit of the food-protection technology outweighs the harmful impact of the packaging itself.

Packaging Fixes Sticky Situations.

One example of waste-reducing packaging is the concept project shown from designer Drew Stanley. He designed a peanut butter jar made of a soft material which can be turned inside out and scraped (刮掉) clean, avoiding sticky food sticking to your fingers.

A. Packaging protects milk.

B. Using Tetra Pak packaging.

C. But packaging isn't always the enemy.

D. We should pay attention to the rubbish produced by packaging.

E. Scientists have developed packaging that can keep refrigerated meat fresh for weeks.

F. It can reduce the need for refrigeration and the amount of milk that goes wasted.

G. Food left behind in jars and bottles makes up a surprising amount of waste.

The pilot program was launched on Sunday on the Daxing Airport Express subway line to spare passengers the trouble of swiping a card (刷卡) or scanning a QR code to catch a train , the Beijing Municipal Commission of Transport said.

Any commuter aged 14 and above can first register the print of either palm through a simple, automated process and provide relevant information to authorize the payment gateway of WeChat, a popular messaging app in China. Once the palm print is registered, a commuter can scan the palm at any automated ticket gate to pass through. The fare is automatically paid after exit. Besides, the registration is a one-time process and doesn't require renewal.

"Passengers can just place a palm above the scanning machine when entering or exiting a subway station. The ticket gate will open if the palm scan matches the palm print registered voluntarily," said Zhang Li, an expert at the Beijing Metro Network Control Center.

The biometric method combines the use of palm print and vein mapping, which are different for every individual. Therefore, data masking and encryption (加密) technologies have been applied to protect user information.

Xin Jianhua, general manager of the public service center at WeChat Pay, said palm scans can be gradually used in offices, schools, gyms and restaurants, as it requires no contact and is therefore safer and more efficient. "Currently, it is very useful for the elderly and those who have physical limitations," he said. "Use of biometric data allows passengers to take subway trains if they do not have cash or when they forget their subway cards," he added.

Yet despite my enthusiasm, learning Chinese hadn't even entered my mind. This wasn't ignorance or laziness, but rather fright at the thought of attempting to learn what is regarded as the most difficult language in the world. In my mind, the Chinese language was the privilege of the highly intelligent.

However, after a year in China I began to feel uncomfortable with how many Chinese people could speak English and yet I couldn't even speak the most basic Chinese. With these factors in mind and a thirst for a new challenge I determined to begin my language journey.

In the two years since starting to learn I have made measurable progress. I found it less difficult than thought. When speaking to native Chinese speakers in Chinese they almost always understand me, I have also not found it too difficult to remember characters and I am now even able to write over +00 characters. I find studying the language relaxing and rewarding.

In spite of my progress, it has still been the challenge that has taken a lot of hard work and commitment. The thing I find most discouraging is listening since native speakers talk at such a speed, I can't always understand what's been said, but my weekly online language exchanges help with this. Furthermore, there is a long way to go before I reach my goal of fluency. The key to progress is to be patient and persistent.

My biggest harvest from learning Chinese is that it's not only reachable but can also be enjoyable. Learning Chinese not only helped me in day-to-day life, but deepened my cultural understanding of such a diverse and interesting country. Now my only regret is that I didn't start earlier.

The summer break had started. Bilal, a teenager, was excited to finally have the free time to play video games on his PlayStation and endlessly surf the internet on his phone. His parents were tired of always trying to stop him, constantly telling him that spending so much time online and on social media wasn't good for his physical health. They worried about his eyesight and the lack of physical activity. But Bilal never listened. He was very addicted to the e-world.

One day, after getting fed up, his mother discussed Bilal with his grandparents. "Is there any way we can get him away from this internet world?" she asked, her voice filled with desperation.

His grandfather replied, "Yes, there is a way. I am planning to visit our village for a week. I am thinking of taking Bilal along. It will be a new experience for him to see a simple lifestyle. Besides, the internet signals are very bad there, so he won't be able to stay online very often."

His mother was happy to hear this. "That's a very good idea," she replied, hopeful that this could be the turning point for Bilal. She excitedly went and shared it with Bilal, hoping he would be happy about going with his grandparents, but he refused, saying the trip would be boring without the internet. "How would I spend my days?" he complained.

Just then his grandmother entered the room and explained calmly to him that it would be an exciting trip. She spoke of the beauty of nature, the joy of community, and the simple pleasures of life away from screens. She told him stories of the village, of the stars at night and the fresh air that filled the lungs with life.

The traditional Chinese Longtaitou Festival, or Dragon-Head-Raising Festival, (fall) on the second day of the second month on the traditional Chinese calendar every year, and is recognized as the start of spring and farming.

A well-known saying goes, "Er yue er, long tai tou," meaning "On the second day of the second month, the dragon lifts (it) head." The most famous tradition is getting haircut. Some believe that (go) to the barber on this day gets rid of difficulties, while others believe getting one during the first month of the traditional Chinese calendar (typical) brings bad luck. Another saying warns that cutting your hair in the first month will cause your uncle (die). today few pay attention to it, it was once a tradition to line up outside barber shops on the day of Longtaitou.

People eat tofu (ball) in East China's Fujian province during the festival, and often make them to pray for family and business. Fried beans are the traditional festival food people in parts of Shandong province enjoy. Eating chengyao cakes, which are made sticky rice (糯米), during the festival is a tradition in Suzhou, East China's Jiangsu province, in tribute to the saying, "If you eat chengyao on Longtaitou, your waist won't hurt all year."

However, Tim tried to cool me down. "It's not easy," he6. "It requires training, not just enthusiasm." But I believed nothing was impossible7 a willing heart. So I8 alone without telling Tim.

The journey was fine at first, but soon it grew9. The path became rugged (崎岖的). Heavy rain came, rocks turned slippery, and my phone had no signal. I was filled with fear.

Around 5:30 PM, I found a weak signal and called Tim. He was10, but after checking my location, he calmly11 me to take a side path down to a village. Though it meant12, I had no choice. Climbing down the path at night was still very challenging. When I met Tim finally, I almost cried.

When we finally13 to the village, I apologized for my recklessness (鲁莽). "You're still a hero," Tim said with a warm smile, "because a hero knows when to stay on and when to give up." But I knew I was not. A true hero knows to respect, and to act14. That was a15 the mountains taught me.

Choose the right time. Don't ask someone for help when they are obviously busy or distracted. For example, don't ask your professor for help with homework right as they are trying to start class.

Be specific. People aren't mind readers. For example, instead of saying to your partner, "I need you to help more around the house," you may say, "Could you please take the trash out and also do a load of laundry, please?"

Be persistent. Sometimes the help you receive might not turn out the way you expected. That can be frustrating. However, it is important not to give up. If you asked someone for help and they didn't come through, don't be afraid to ask someone else. Sometimes, you may need to reach out to a few people before getting assistance.

People will be more likely to agree to help you if you have been known for helping others. If you see a co-worker who has too much on their plate, offer your assistance. They'll likely return the favor when you' re tired and stressed.

A. Return the favour if possible.

B. Build a name as a helpful person.

C. Unfortunately, it can feel difficult to ask for help.

D. Keep trying to get help and make it work for you.

E. It is important to remember that it is not weak to ask for help.

F. Similarly, don't ask your boss for advice as they are rushing out the door.

G. Instead of just saying "I need help," clearly state precisely what it is that you need.

The northern quoll is a small marsupial found in northern regions of Australia. Its population has dropped a lot because of introduced predators (捕食性动物) such as cats and the loss of habitat. But the biggest threat is the invasive cane toad, which produces a toxin (毒素) that kills animals.

Stephen Frankenberg at the University of Melbourne and his colleagues want to edit the genes of the northern quoll to make it able to resist the toxin. "We only change a few parts of the quoll's DNA," Frankenberg says. "Nature might make this change on its own, but that would take thousands of years if quolls lived with toads all that time." If these gene — edited quolls can stand the poison well, they will have a high chance of survival when they eat a cane toad.

"Other ways to save them have failed," Frankenberg added. For example, his team tried to teach northern quolls to avoid cane toads, but this did not work on a large scale. Yet not much progress has been made in changing the quoll's genes. In 2020, the team had used gene editing to introduce toxin resistance into cells growing in a dunnart, which is in the same family as quolls, but is easier to work with.

Now, the team is about to release a study showing that the edited dunnart cells are 45 times as resistant to the toxin of cane toads as normal ones. However, the real challenge isn't editing genes in the lab. Changing the genes of animals is easy for well — studied ones like mice, but often fails in other species. It needs many animals to test on. That is especially difficult with endangered species. "I like the idea and think it is worth exploring," says Merlin Crossley at the University of New South Wales in Sydney. "But the hardest part is still to come," he says.
