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!

George had his eye on a scoring record. He took a deep breath as he stood in the doorway,looking in at the basketball court. The gym was old and small, but it held a long history. Maybe today I'll make history, George thought.

His basketball league was celebrating. Today's championship game marked its 50th anniversary (周年) since the league's first championship.

George looked over the brochure for the anniversary. It listed the winners of each championship game and the top scorers. He stopped suddenly when he read the name of the top scorer from a game 30 years before. He quickly went through the rest of the list. "Look!" he said to his teammate David,showing him the brochure."You see who has the all-time record? My dad! He never told me that."

"24 points," David said. "That's awesome!"

George's best record was 19 points. He was the Badgers' top scorer. "It seems that my dad never showed off something like that,"George said.

When his parents arrived, George brought the brochure over to them. His dad laughed. "I didn't miss a shot in that game. But look at the score. I would have traded every shot for a win,"he said with regret. George hadn't noticed that his dad's team had lost the game just by one point."That was a great group of teammates,"his dad added."You have great teammates in the Badgers, too."

As George warmed up, he was still digesting his father's words. "This will be a struggle every second,"the coach emphasized before they got on court to play."I want to see tough defense, sharp passing, and, above all, smart play as a team."

George was confident he could lead the Badgers to victory, just as he did in their previous games against the Lions. And he played really hard. As the game neared its end, George had already scored 23 points. Another basket would break his father's scoring record.
