Chinese scientists have recently developed a new form of technology, can quickly and accurately measure the sensory qualities of pumpkins. This achievement, (make) by researchers from the Hefei Institutes of Physical Science, combines two advanced technologies, Near-Infrared Spectroscopy (NIRS) and Hyperspectral Imaging (HSI) .

(traditional) , pumpkin quality evaluation proved a slow and subjective process, with farmers often relying on cooking and tasting (measure) sweetness and other relevant factors. new method, however, allows for a more objective evaluation by analyzing critical elements like starch (淀粉) and moisture content.

In their efforts to develop this new type of technology, the team (collect) 97 pumpkin samples from 34 different pumpkins. (use) NIRS and HSI methods, they created predictive models to assess sensory quality based on the starch and moisture content in each pumpkin.

According the researchers, their current experiments are based on sliced pumpkins, while the new technique can also test quality without damaging the pumpkin.

Moreover, a researcher said that this technology could (apply) to other fruits and vegetables as well. "We are currently developing customized solutions based on specific (requirement) . For example, companies could use it to check sugar content in apples or vitamin levels in oranges. "

Her three children, 13-year-old Oliver, ten-year-old Lucie and nine-year-old Jacob,2 their recent CPR training at Southam Fire Station, stayed3, and with the advice of the 999-call operator,4 CPR to keep their mum alive until help arrived.

Although Kayleigh5 her condition well, she wanted her children to6 the right skills should anything happen to her as a result of her condition.

So last summer she sent them on a first aid7 run by Warwickshire Fire and Rescue Service. Little did the family know the skills8 would be put to the test so soon.

Kayleigh said, "I couldn't be9 of my children. They stayed calm. For a ten-year-old to calmly perform CPR, while the other children called 999 in order to save my life is just10. I would like to express my11 to Warwickshire Fire and Rescue Service for the training they gave to the children which12 saved my life."

Chief fire officer Kieran Amos said, "As a fire and rescue service, we know how13 it is to have the right skills to save a life. As a service, we are just thankful that we can play a role in the community which14 fighting fires, yet still has a direct15 on keeping people safe and saving lives."

Open your mind

Reading opens your eyes and mind to a world beyond your neighborhood. You can find out about people living different lives to you. . You discover important news stories and how you can make a difference in the world. Reading non-fiction and fiction improves your understanding of people and the world around you. Sarah Driver, a teacher for 25 years, says, "Reading helps you understand how other people feel because you get to see things from their eyes. . "

Inspire your imagination

Your creativity gets improved from reading too. As Driver says, "You begin to picture the story in your head and create your own images. It helps you to think of new ideas and come up with different ways to solve problems. . "

Make new friends

Reading can also bring you closer to your friends. , it can help you to make new friends. Besides, you can create a book club where you take it in turn to choose what to read and talk about it together.

There are times when you may want to escape into another world. You can do that with a book without going anywhere. When you're reading a story that captures your imagination and your attention, you forget everything around you. If you're feeling tired, upset or lonely, getting lost in a story can give you comfort and help you to relax.

Finns do just that. Half of women and a third of men bike to work. About a fifth of the country belongs to sports clubs. Some people even play sports at work. For example, every Wednesday morning, a group of scientists at the University of Jyväskylä leave their desks to play "futsal", an indoor form of soccer, in a gym across the street. It's one of the most popular team sports in the country, along with floor ball and Finnish baseball. A nearby chocolate factory has a gym and offers aerobics classes.

"Employers started to encourage sports participation about a century ago in the forestry industry," says Hanna Vehmas, a sports scientist at the University of Jyväskylä. "Nowadays, 90% of employers support their employees' physical activities in some way. Each year, they spend an average of about $220 per employee for physical activities."

One reason why employers tend to support their employees' physical activities is due to a tax break. Businesses can deduct (扣除) money spent on employees' physical well-being.

"But there's something else. We have a lot of research showing that spending money on employees' well-being will bring back as much as six times the money spent," says Vehmas. "Because healthy employees do better work. They also don't have as many sick days. And staying fit, especially by playing sports together, could help build company loyalty (忠诚) which is actually even more important than the health side."

Physically active people also save the health care system a lot of money. Data from the Finnish Ministry of Social Affairs & Health shows that people who bike and walk save the health care system as much as $5.5 billion each year.

The teamwork has led to the creation of a water-soluble fluorescent spray (水溶性荧光喷雾) that significantly advanced the detection of possible fingerprints. Unlike traditional methods that often involve the use of poisonous or environmentally harmful chemicals, this innovative spray offers a safer and greener choice.

By targeting the invisible prints left behind by sweat or oil on surfaces, the spray quickly makes them visible within seconds, promoting convenience and speed in forensic investigations. According to researchers, its water solubility further improves its applicability, allowing for adaptable use directly at crime scenes.

Detecting latent (hidden) fingerprints (LFPs) is important in forensic science, but their invisible nature poses challenges. Traditional methods like powder dusting and chemicals have limitations in speed and safety. Using the fluorescence properties of Green Fluorescent Protein (GFP), the researchers have developed two distinct dyes (染料) — LFP-Yellow and LFP-Red to address these challenges. These dyes exhibit an "off-on" fluorescence response upon different parts of LFPs, by selectively attaching to small elements present in fingerprints. Under blue light, they give out a soft fluorescent light, enabling easy detection. Developed from jellyfish (水母；海蜇), GFP serves as a biological basis for these dyes, ensuring they do not affect the following DNA analysis of the fingerprints.

According to researchers, applying these dyes involves a fine spray, which prevents damaging spots and offers a cleaner way, compared to traditional methods. It works perfectly even on rough surfaces like brick, where collecting fingerprints can be particularly arduous.

"This system can even be used on fingerprints that are a week old. Having two different colors available means the spray can be used on different colored surfaces. We're hoping to produce more colors in the future. We're looking for cooperation with various companies to bring the dyes to market for wide availability. Additionally, ongoing research and development efforts will be needed to continue to improve their products," said Professor Tony James, from the University of Bath.

After moving to the city, she began missing the farm. Faced with the limited space, Padma felt the absence of fresh vegetables. Besides, she was disappointed with the taste and quality of shop-bought vegetables. Because chemicals used on vegetables were harmful to human health, she finally decided to take matters into her own hands and change her yard into a vegetable garden.

Now 48, Padma has devoted the past 12 years to developing a garden with 200 plants of 20 varieties of vegetables. She relies on natural fertilizers (肥料). Additionally, she uses creative organic farming methods like preparing liquid fertilizers from fish.

Her husband Suresh Ettan, who is now working in an oil and gas company, said, "As I don't eat meat, I have limited food choices in the city. Now every morning, my wife sends me a good breakfast. Apart from that, she also shares the photos of her day's harvest. I take pride in showing those photos to my colleagues."

For Padma, the garden has become a source of joy and also a link to her rural roots. Padma says she finds connection to her village through the traditional recipes and taste of homegrown vegetables. More importantly, by growing her own food, the gardener has not only found a way to provide a supply of organic vegetables to her family but also a way to earn some money. Earning money was what she didn't expect. Padma says she has a small shop where she sells extra vegetables. Within an hour, all her vegetables are sold out. This organic farming business earns her up to Rs 1,000.

Named "Blazing Beacon" after the watchtowers along its walls, Dunhuang was once a vital meeting point at the gateway to China. The routes that joined here ran through Constantinople in the West and Japan in the East. But there was more to this blooming oasis than trade. For over 1000 years, Dunhuang was also an important religious site, a cultural melting pot where ideas, technologies and art flowed freely.

This exhibition provides a rare glimpse into the ordinary lives of people long ago through the remarkable contents of the Library Cave, the documents include personal letters and wills concerning multiple languages, faiths and cultures including Buddhism, Zoroastrianism, Manichaeism and Christianity; and span topics as diverse as literature, astronomy, medicine, politics and art.

Exhibition Highlights:

The Diamond Sutra (868 CE): The oldest complete printed book with a date, significant in Mahayana Buddhism in East Asia.

Dunhuang Star Chart: The earliest known map of the night sky from any culture, showing early astronomical knowledge.

Old Tibetan Annals: Tibetan, detailing the Tibetan empire from 641 to 764.

A typical American high school has several large buildings and enough space for about 1,500 students.When students first arrive at school, they go straight to their lockers (寄存柜，有锁存物柜) to put away or get their textbooks and to hang up their outdoor clothes. As American textbooks are expensive, students would rather rent than buy them.

American students have different types of school transport. They usually take a yellow school bus or walk to school if they live close enough. When they turn 16 years of age, most take a free driving class at school for one term. If students earn passing grades in the class and also pass their state driver's exam, they can begin driving themselves to school.

They must take science, math, English and social studies. They can choose art, homemaking, fashion design and other classes. In some schools students are required to take one or more of the following special classes: health education, physical education or foreign language studies. Students move to different classrooms for each subject. This is because each teacher has their own classroom. There is a five-minute break between classes, to give the students the time to hurry to their next class.

The regular school day usually ends early in the afternoon. After school more than half of the students are involved in after-school activities. These activities include sports-especially football, basketball, baseball and soccer or clubs, such as yearbook, speech, school newspaper, photograph or student government.

A. Every student is given a locker.

B. Each day, students take six or seven classes.

C. Sometimes their parents drive them to school.

D. Students must pay back if they lost any of them.

E. Because each teacher has their own classroom.

F. In some schools students are required to take some special subjects.

G. This article will describe a typical American high school and its students.

The third-place winner was announced. The name was not mine. Then the second-place winner, still not me. At last, the moment of truth came. I was about to either enjoy the warmth of victory or regret the months' preparation. My heart felt closer to the latter.

Losing is a part of life, and I have dealt with it on more than one occasion. However, it was an indescribable feeling to drive a 200-mile round trip, get up very early on a freezing Saturday morning, and yet still finish fourth out of four competitors in my group.

I had spent many hours in front of a computer and in libraries doing research for the Lincoln Bicentennial (200周年) Speech Contest. After not placing (获得名次) in the first year of the contest, I really wanted to compete again. Lincoln had many failures, but he never allowed them to defeat his spirit or ambition, so I was not going to give up on a second contest! I reworked my speech for the following year, but again I did not place.

I couldn't accept the fact that I failed twice in something that I had worked so hard on, until I thought about my hero. Never mind the lost prize money and praise—through learning stories about Lincoln, I discovered that I can fail successfully.

We met in the Children's Hospital.I was 11. I was born with a hole in my heart. So was the five­year­old girl in the bed beside me.We were both recovering from the same operation.Because I was older and wiser, I thought it was my job to look after her. "Do you want to hear a story?" I asked her one afternoon."Great!" she said.

It was so easy to make her happy.She seemed always to be smiling or singing songs.

Life wasn't fair. She passed away. My recovery went well. "You're really lucky"，a nurse told me."But how come my operation was so easy and hers wasn't?" I asked."Easy?" my dad said. "David, your operation wasn't easy at all. We thought we were going to lose you. For two weeks after your operation, many things could go wrong. You're really lucky. When you were in the coma (昏迷) , she used to come over to your bed and sing to you. She was watching over you." my dad said.

My surgery scars (手术疤痕)are hidden under my shirt along with the memory of that kind little girl. She will be at my side like a small angel. I am old and wise enough now to know that I have an angel watching over me whenever life is fair or unfair.

Must-See Attractions

Most visitors begin their Amsterdam adventure in the Old Centre, which is full of traditional architecture, shopping centers, and coffee shops. You'll also want to check out Amsterdam's Museum Quarter in the South District, which is great for shopping at the Albert Cuyp Market and having a picnic in the Vondelpark. The top museums to visit there are the Rijksmusuem, the Ann Frank House, and the Van Gogh Museum.

If You Have Time

There are several other unique districts in Amsterdam, and you should try to explore as many of them as time allows. The Canal Ring is a UNESCO World Heritage Site that was originally built to attract wealthy home owners and is a center for celebrity spotting and nightlife today. The Plantage area has most of the city's museums and the botanical gardens.

Money Saving Tips

●Unless you really want to see the tulips(郁金香) blooming, avoid booking between mid-March and mid-May. This is when hotel and flight prices rise.

●Look for accommodations in Amsterdam's South District, where rates are generally cheaper than in the city center.

●Buy train tickets at the machine instead of the counter to save a bit of money.

●Instead of hiring a tour guide, hop on a canal boat. They're inexpensive and will give you a unique point of view of the city.
