Learn Better With the Feynman Technique(费曼学习法)”
What is the Feynman Technique Albert Einstein once said, “If you can’t explain it to a child, you don’t understand it well enough.” This idea is similar to the Feynman Technique, which suggests the best way to understand something is to try to explain it in a simple, clear way.
Why is the Feynman Technique
When you are called on to explain some details of a concept(概念), you will find your knowledge gaps(缺口). And communicating the knowledge you understand well to others seems difficult sometimes. When you learn with the Feynman Technique, you will not only understand the concept better but also improve your communication skills. You are killing two birds with one stone.
How to use the Feynman Technique
1. Choose a concept to learn
Firstly, you need to choose a concept you’re interested in and start studying.
2. Teach it to yourself
Write down an explanation of the concept in your own words on a piece of paper and explain it to yourself. Make sure that someone without your background knowledge would be able to understand.
3. Fill the gaps
In step 2, you will find some gaps in your knowledge. Then you need to go back to studying until you feel that you are ready for your explanation.
4. Organize and review
To test your understanding in the real world, explain it to someone. Do they get it What questions do they ask Their answers can help you learn better.
Put your paper with your simple explanation into a binder(活页夹). And remember to look through it a few times every year.
The Feynman Technique emphasizes explaining concepts in a way that is ______.
A. highly technical B. simple and clear C. filled with jargon
What is the main purpose of filling knowledge gaps
A. To ignore weaknesses B. To strengthen understanding
C. To avoid studying
3.Step 4 of the Feynman Technique involves testing your explanation by ______.
A. writing a summary B. teaching it to someone else
C. memorizing key points
4.Why is the Feynman Technique effective for learning
A. It helps you teach others and find gaps in your knowledge.
B. It allows you to copy others’work.
C. It focuses only on reading textbooks.
5.The phrase “killing two birds with one stone” in the text means ______.

Meet Sun Lei
Many boys are crazy about armor(盔甲), and Sun Lei from Xuzhou, Jiangsu Province, is one of them. But here’s the cool part — he didn’t just stay as being a fan. He has turned himself into an armor craftsman!
Sun was born in 1994. When he was young, he practiced martial arts and read books on martial arts. His fascination with ancient armor took root in his heart.
In 2010, Sun went to university. At university, he tried making his first set of armor by hand. Without a teacher or clear guidance, he had to learn everything by himself. The journey was difficult.

Making a set of armor requires many skills such as painting and carving(雕刻).

If he is not satisfied with something, he will start all over again. To ensure(确保) its practicality(实用性), he even wears the armor to do some training like horseback riding.
Now, Sun Lei has made more than 6,000 sets of armor. He plans to make more and open a museum of ancient Chinese armor one day. Give our best wishes to him.

Food Hero — Li Zhensheng
Li Zhensheng, a great Chinese scientist, has visited more wheat fields than he could ever count during his 70-year career(事业) in wheat breeding(小麦育种). Throughout his life, he’s been doing one thing — making sure that the Chinese people have enough to eat, and that they eat well.
Li was born in 1931 in Zibo, Shandong. His early life was full of hardships. He was a teenager during the great famine (饥荒)of the 1940s. He saw how difficult people’s lives could be because of food shortages. He hoped that nobody would ever experience hunger again, so he majored in agriculture(农业) at Shandong Agricultural College.
In 1956, Li answered the government’s call to support the northwestern area and went to work in Yangling, Shaanxi. There, Li and his team spent over 20 years developing a kind of wheat named “Xiaoyan” series, which grew fast and didn’t get sick easily. By 2003, over 20 million hectares(公顷) of “Xiaoyan” wheat had been planted nationwide.
But Li’s breakthroughs didn’t stop there. In 1987, he started a project to improve farms in the Huang-Huai-Hai area. This project added about 25 million tons to China’s grain production. In 2011, he started a project called the “Bohai grain silo” that turned land that was too salty into good farmland. This project helped grow over 10 million tons of food in the Bohai area.
Now, even though he is in his 90s and is unable to go to the fields, Li still helps young scientists learn about farming. “Follow the needs of the country and choose wisely what you wish to achieve,” Li told them.
1. What has Li Zhensheng devoted his life to
A. Studying ancient Chinese history B.Ensuring Chinese people have enough food
C. Developing new medicines D.Teaching university students
2. Why did Li Zhensheng choose to study agriculture
A.To become a famous scientist B. To escape poverty in his hometown
C. To prevent hunger after experiencing famine D. To follow his family’s tradition
3. What is special about “Xiaoyan” wheat
A. It can grow in salty soil B. It matures quickly and resists disease
C. It requires no water D. It was imported from other countries
4. How much farmland was planted with “Xiaoyan” wheat by 2003
A.10 million hectares B. Over 20 million hectares
C. 25 million tons D. 5 million hectares
5. What did Li’s Huang-Huai-Hai project achieve
A.Increased grain production by 25 million tons B. Invented new wheat seeds
C. Built modern grain silos D. Reduced farmland pollution
6. What does the “Bohai grain silo” project focus on
A. Planting wheat in deserts B. Transforming salty land into farmland
C. Developing organic farming D. Protecting endangered crops
7. What advice does Li give to young scientists
A. Pursue personal fame B. Focus on international research
C. Follow national needs and set clear goals D.Avoid fieldwork in old age

On the subway, by the bus stop, on the train stop and so on, we often see people watching micro-dramas (微短剧) on apps like Kuaishou and Douyin. 1 In 2023, micro-dramas made 37.39 billion yuan,equal to 70 percent of the money made by China's film industry.
2 Sensor Tower, a US company,said that over 40 apps for watching the dramas have entered the global market. By early 2024, these apps already had around 55 million downloads (下载量). One of them, ReelShort, has been downloaded more times than Netflix on the Apple Store in the US, reported Reuters.
International viewers find these micro-dramas exciting to watch. The stories are usually fast-paced and have many surprising twists (转折). 3
The short period of the dramas adds to their popularity. 4 People can finish a micro-drama in short length of time, such as on their way to work. Also, most micro-dramas are filmed vertically (竖向地). This allows people to watch them comfortably without having to turn their phone screen.
Going forward, micro-dramas could open new doors for China’s cultural exports (文化输出). 5 The dramas should cover more topics, not just the usual ones like time travel.

1.[答案] A
[解析] 写作手法题 由第一段可得知,文章开头直接描述了事件的时间、地点和人物,属于陈述事实。B选项(举例子),文中并未用具体例子引入;C选项(列数字),文中虽有数字10-year-old,但不是主要开篇方式;D选项(提出问题),第一段并未以问题形式开篇。故选A。

1. [答案] spring
[解析] 根据常识,清明是春季的节气,所以这里填“spring”,表示“春天”。
2. [答案] when
[解析]“It is a time...”后面是一个定语从句,先行词是“time”,在从句中作时间状语,所以用关系副词“when”引导。

4. [答案] second
[解析] 前面提到了“in the first hou”(在第一个气候),后面提到“in the third hou”(在第三个气候),所以这里说的是“第二个候”,用“second”。
5. [答案] change
[解析] 根据语境,这里表达的是古老的说法并不是说田鼠和鹌鹑互相“变成”对方,“change into”有“变成”的意思,且前面有助动词“doesn't”,后面用动词原形,所以填“change”。
6. [答案] avoid
[解析]田鼠喜欢阴暗的习性意味着它们躲在洞穴里是为了“避开”阳光和捕食者,“avoid”是“避开;避免”的意思,且“to”后接动词原形,故填“avoid”。
7. [答案] looking
[解析]“see sb. doing sth.”表示“看见某人正在做某事”,这里说的是能看见鹌鹑在田地里“寻找”食物,考查固定搭配“look for寻找”的意思,所以填“looking”。

[解析]根据前文“The old saying doesn't mean...but is a way of saying...”可知这里也是表达“另一种说法”,“a way of doing sth.”表示“做某事的一种方式”,所以填“way”。
9.[答案] considered
[解析] “be considered as...”是固定短语,意思是“被认为是……”,这里说清明是唯一被认为是中国主要节日的节气,所以填“considered”。
