I used to be very shy and often felt lonely. Although I did well in all the academic subjects, I was afraid of physical education. My classmates often laughed at me.

"Look at that girl," they said. "Her feet don't leave the ground when she runs!"

Their words embarrassed me. Moreover, whenever the teacher organized some competitive games, no one in the class liked to have me as their partner or team member. As a result, I often ended up looking at others enjoy their games.

Things would go on like that if not for a sports meet in my high school. By mistake, my name was put on the list of those who would compete in the women's 1500 meters race. By the time people found the mistake, it was too late to change.

I was utterly dumbfounded (目瞪口呆的). 1500 meters! Running against the best runners from other classes! And in front of students of the entire school! It would be the worst nightmare I'd ever have!

"You still have time to catch up because there is still one month before the sports meet," my classmates all said this to me, including my teacher.

My desk-mate patted me on the shoulder, "Cool! You will run for our class! And we will do training together." Yes, this is not just for myself, but for my class too, I said to myself. But still, 1500 meters to me was like Mount Everest to a beginning climber. I had no idea even how to start my preparation.

Fortunately, my desk-mate gave me a hand. Every afternoon after class, several of us ran together. They gave me strengths. While we were running, some others would stand by the tracks cheering for us.

One month certainly couldn't make me a good runner. But when I was standing behind the start line, I no longer felt lonely or afraid. I saw my classmates standing by the tracks waving at me as if about to run beside me.

The day finally came!

No structure is as symbolically significant or (cultural) important to China as the Great Wall. Architectural (engineer)are part of a huge project to repair this centuries-old structure.

Jiankou (believe) to be one of the most rugged stretches of the relic. Some of the most dangerous work includes laborers hanging from towering heights. With ropes tied around (they) waists, repair workers spread cement on the wall's steep sides, while others hold the ropes for support. (survive) a fall from the steep sides would be unlikely. A laborer explains he risks his life to make repairs to the ancient structure, saying that it is an honor to be part of such a great cause, and it is very (meaning) to do so.

Getting supplies to this part of the wall is also a demanding effort. Because the path is so steep, donkeys and mules must be used to transport bricks, can weigh as much as 150 kg each. The repair team goes to great lengths (keep) the principle of minimal intervention. "We have to stick the original format, the original material and the original craftsmanship, so that we can better preserve the historical and cultural values, " said Cheng Yongmao, the engineer leading Jiankou's restoration work.

As soon as we2, we were greeted by the boys and girls assigned (分派) to meet us. After we left the airport, we3 a bus and it was there that we faced a(n)4 difference. As everyone says, "Italians are noisy, more open and outgoing", and this is what differentiates us from the Germans, who are much more reserved and5. On the bus, as we had a long way to go, we decided to listen to some6 and sang out loud, and these kinds of things are often done during school trips by Italian7. When we were glancing at all the German kids, we decided to8 because we realized our behavior led to a(n)9 climate for them.

After we settled down, we decided to have lunch in a restaurant. Shortly before entering that10, I recognized another difference between the two cultures.

This exchange made me14 the differences within cultures and how cultural shock works.15, I learned what seems normal to me can be something improper in another country, even if that country is just a few miles away.

Determine the basics

When you first see an artwork, identify some basic information about it. Try to determine its medium (材料). If it's a painting, see if you can figure out the type of paint used.. These observations can build a foundation for better understanding.

Artists are masters of drawing attention. They usually have a plan for how your vision should move across the artwork. Taking note of what you notice first is a useful way to begin your experience. For example, it is said that Renaissance artists would refer to their paintings as "machines". Their intention was to allow viewers to move their eyes smoothly through the work of art with clarity (清晰) and balance.

Do some homework

You don't need a background in art to appreciate it, but having some knowledge doesn't hurt, either. If a work of art catches your attention, do a little research, read an exhibition's catalogue (目录) or speak to the art team..

Feel the artwork

. Is the artwork artful or dramatic? How does it affect your feelings? Do you feel sad, happy or angry? These questions require immediate reactions. They can be subjective, but they are worth considering, because art is about the artist communicating and expressing ideas.

A. Notice your eye movements

B. Spend some time with artists

C. All these can deepen your appreciation

D. Recognize your feelings as you first view the art

E. You can also identify the artist and when it was created

F. Try these tips next time you're viewing art, and they might help you

G. You'd be surprised by the knowledge you can acquire when interpreting art

One in three UK consumers throw away food just because it reaches the use-by date, but 60% of the £12.5 billion-worth of food we throw away each year is safe to eat.

The researchers, whose findings were published in ACS Sensors, say the sensors could also eventually replace the use-by date—a widely used indicator of being fresh and eatable.

The sensors cost two US cents each to make. Known as "paper-based electrical gas sensors (PEGS)", they detect spoilage gases like ammonia (a poisonous gas with a strong unpleasant smell) in meat and fish products. The information provided by the electronic nose is received by a smart phone, and then you can know whether the food is fresh and safe to eat.

The Imperial College London researchers who developed PEGS made the sensors by printing carbon electrodes onto a special type of paper. The materials are eco-friendly and harmless, so they don't damage the environment and are safe to use in food packaging. The sensors, combined with a tiny electronic system, then inform nearby mobile devices, which identify and understand the data about spoilage gases.

Lead author Dr Firat Guder of Imperial's Department of Bioengineering, said, "Although they're designed to keep us safe, use-by dates can lead to eatable food being thrown away. They don't always reflect its actual freshness. In fact, people often get sick from food-borne diseases due to poor storage, even when an item is within its use-by date."

"These sensors are cheap enough so we hope to see supermarkets using them within three years. Our goal is to use PEGS in food packaging to reduce unnecessary food waste."

The authors hope that PEGS could have applications beyond food processing, like sensing chemicals in agriculture, air quality, and detecting disease markers in breath like those involved in kidney disease.

Another prediction on the Internet is that data transmission (传输) speed will increase globally. According to Akamai Technologies, the average global data transmission speed in late 2019 was 26.7 megabits per second. Compare that to the record for data transmission speed set by Bell Labs: 100 billion megabits per second. At that speed, you could transmit 400 DVDs worth of data every second. That's an enormous gap between what's currently possible and what's commercially available. But as time passes, the costs of producing super-high-speed networks will decrease.

In the future, people will live under the sea and the housing shortage will be solved. There will be lots of glass domes (穹状建筑物)under the sea, which allow people to look all around into the sea. Air will be provided via air pipes which lead to the open air. You can travel from one dome to another via a kind of submarine which will also be made of glass. The domes will be so beautiful and the view under the sea will be so impressive that many people will prefer to live under water, and less people will prefer to live on land. This will have a positive effect on the environment on land.

In the future we won't use oil or gas as energy any more. We will make use of sunlight, water and wind. Cars will run on water. Just fill your tank with water, and you can drive further than you could drive with the same amount of gasoline. Also, the exhaust won't be damaging to the environment, because it'll just be water vapour. So the water cycle won't change, we'll keep the same amount of water on the earth, and we won't run out of water. Also, all energy will be supplied by natural sources: sunlight, wind and water.

"Birdcage effect" means that when you get an item one day, you will prepare more things to match it. Weeks ago, I was in the company of friends engaged in shopping. One said that she wanted to buy a good writing pen to match the delicate notebook that her sister gave her, so that she would fall in love with taking notes on reading, and thus love reading, not just reading. I joked that she must have fallen for the "birdcage effect". But the friend said with a smile: "Why not use the ‘birdcage effect' instead?"

For the first time, I heard that the "birdcage effect" can be used in reverse (逆向). However, this can't help but remind me of middle school, and I seem to have used the "birdcage effect". Passing by a bookstore one day, I purchased a magazine and saw the call for contributions published in the magazine, so I started writing with eager hands, and then I fell in love with writing.

After shopping with my friends that time, I began to proceed to use the "birdcage effect". I bought a small fresh tablecloth to decorate my desk, and a beautiful notebook to record my inspiration. When everything was ready, I started writing again.

But how can we get rid of the "birdcage effect" in many things, and even use the "birdcage effect" in the opposite way? Various "birdcages" unavoidably appear in life, but we can distinguish them. If it is not in line with the actual situation, it is a "negative birdcage", then we must learn to stop losses in time and maintain a heart of abandonment and separation. If it is a "positive birdcage" that motivates us to develop upward, we can clarify our goals, shop or decorate appropriately, and motivate ourselves to move towards our goals. At this time, you will find that the "birdcage effect" is actually not so terrible!
