In China, Tree Planting Day falls on March 12, but more often people plant trees during Qing Ming Festival in early April. Newly-planted trees can survive more easily with a     1     (warm) climate and frequent spring rainfall at that time.

China set March 12     2     the National Tree-Planting Day in 1979 to memorize Sun Yat-sen (孙中山),     3     died on March 12, 1925. Sun had called for planting trees.

Since 2013, President Xi Jinping has joined Beijing citizens in tree planting activities for nine years in a row. President Xi called on the public     4     (stick) to the tradition of planting trees in spring. “Students should establish an awareness of protecting     5     environment and cherish the green plants,” Xi said in 2017 when     6     (attend) a tree planting activity in Chaoyang district of Beijing.

China has seen a remarkable     7     (grow) in forest resources and afforestation(造林) projects. Nationwide voluntary tree planting campaigns in China over the past four decades     8     (see) increased participation by members of the public and nearly 79 billion trees have been planted. The campaign has made China the country with the largest increase in forest resources and the largest area of     9     (plant) forests.

In the future, China will launch more effective     10     (measure) to fulfill the country’s climate commitment to peak (达到峰值) carbon dioxide emissions before 2030 and achieve carbon neutrality (碳中和) before 2060.

We believe that acts of kindness can change the world for the     1     (good). On April 28,       2     (country) across the world will unite with one common goal:to stand for kindness together. Pay It Forward Day helps conduct a series of goodness     3     (feel) across the globe.

Pay It Forward Day, a worldwide celebration of kindness,     4     (create) in 2010 in the United States, working hard to bring forward     5     concept of paying it forward to the world at large. We are excited that we now have over 80 countries     6     (participate)   in Pay it Forward Day with over 100 state and city proclamations.

Of course,     7     we all hope is that people pay kindness forward every day and make each day a little bit brighter. We believe that small acts, when multiplied by millions of people can     8     (definite) have a deep impact on the world—and on April 28th we’ll set out to prove it! For this year's international Pay it Forward Day(PIFD)we are aiming to inspire over 10 million acts of kindness around the world. Imagine the     9     (different) that would make! Join us     10     paying it forward and help spread the word about this important day!

Will you eat everything in your lunch box today? If not, will you save it for another time or just throw it away?

A recent study     1     (find) that 17% of all the food     2     (produce) around the world gets wasted each year,     3     reaches about 931 million tons. Believe it     4     not, 61% of the waste happens in our houses!

Food waste in homes     5     (happen) in rich countries like the US and the UK as well as in poor countries for different reasons.

Cultural habits could also lead to waste at home,       6     (include) massive packaging and “buy one, get one free” deals. ‘Use by’ or ‘best by’ dates       7     products could also cause people to throw away food. People could throw out food because they think it is     8     (safe) to eat, when in fact the date only shows when quality might go down.

Food was     9     (much) valued even in richer countries just a few generations ago, because people often couldn’t afford to waste it.     10     (throw) away food is for sure a great waste and we should try to make people know the importance of saving food.

A few weeks ago, I accidentally dropped a plate and it broke into a billion pieces! I’d had it for about 40 years. This morning, we had a parcel     1     (deliver) to my son. He opened it and     2     (proud) handed a new plate to me, which he had bought with his own savings, saying that he knew     3     upset I was and wanted to surprise me!

I’m not Chinese, but I love Chinese New Year. There are many fun New Year     1     (celebrate), but nothing quite matches the excitement of the lion dance which can wake up the spirit     2     (complete).

The sound of the drums,       3     you can feel throughout your entire body, is quite inspiring. The two performers are very flexible. But it is actually very difficult as the lion head is very heavy and being the     4     (low)part of the lion is tiring as he has to bend his back and also carry     5     person in front sometimes. The lion head is made with paper over a bamboo frame,       6     (cover)in gauze (纱布), and decorated with beautifully-colored materials.

The lion dance     7     (believe)to have first appeared in the Qianlong Emperor's dream during his Southern tour, and he ordered an animal     8     (make)in the likeness of his description and used in festivals from then on.

I love all about the lion dance. The other day, I saw a film about a left-behind teenager who insisted on pursuing his dreams despite difficulties and     9     (succeed)in lion dance. As Master Xu translates: “Heaven has made us talents; we’re not made     10     vain.”

Lots of foreigners don’t understand why so many Chinese people are sorrowful about Yuan Longping’s passing away.

This reminds me     1     an issue more than 20 years ago,     2     I was a Chinese journalist in the US. Some American scholars     3     (think) China could hardly realize food-sufficiency because of the     4     (limit) water resources, decrease of agricultural land due to industrial     5     (expand) and the fast population growth. Just at that time, Yuan Longping announced breakthroughs in planting the new rice.     6     (bring) to large area application, this technique improved the annual growth of rice greatly, which fed     7     population of 60 million--equal to the whole of the UK.

Western scholars’ prediction of China back then was indeed analyzing China’s problems, but they failed     8     (realize) that the Chinese people have the capability to deal with these challenges.

If they had had any knowledge of Yuan who worked devotedly for our country, they wouldn’t have made such pessimistic evaluations. Why did the Chinese people make     9    ? Why are so many predictions about China in the West     10    (accurate)? It’s time to change minds to better understand China.

The “24 solar terms” are a vital part of the Chinese calendar, which has     1     (it) origin with the ancient Yellow River basin. The Chinese calendar     2     (include) “24 solar terms”provides detailed guidelines and timetable for agricultural     3     (activity).

A complete set of “24 solar terms” first     4     (appear) in an ancient book The Huainanzi in early Han Dynasty. These 24 solar terms were soon absorbed into The Taichu calendar, the first well documented calendar in     5     history of China.

The Chinese Agriculture Calendar is     6     (actual) a combination of the lunar and solar calendar systems. There     7     (be) 365. 2422 days in one “sidereal year” while 12 lunar months add up to 354 days. To make both the lunar calendar     8     the solar calendar agree, a leap lunar month needs to be added every 2 to 3 years. Since the early Han Dynasty, a lunar month without a major solar term     9     (adopt) as a leap month (闰月) .

With more far-reaching cultural exchanges, the “24 solar terms” have been known     10     people in other parts of the world and were added to the “UNESCO World Intangible Cultural Heritage” list in 2016.

With the International Conference on Food Loss and Waste closed on Saturday in Jinan, Shandong Province, the country has sent a signal to     1     world that China will deal with issues concerning food security by reducing loss and waste in agriculture. With the theme of reducing food loss and food waste and promoting     2     (globe) food security, the three-day event     3     (hold) both online and offline attracted more than 300 participants.

The current world grain production is about 2.8 billion tons a year. Therefore, the loss of only one percentage     4     (be) equal to the loss of 28 million tons of food. This can feed about 70 million people.

In recent years, China     5     (make) great progress in controlling loss and waste in food, with main efforts including upgrading facilities and     6     (equip). In Shandong Province, China’s major grain producer, the Sinograin (中粮集团) grain storage site is equipped with 4,500 high-definition cameras and 280,000 temperature sensors     7     (ensure) that the stock (储备) is in the best condition. Data shows that during China’s 13th Five-Year Plan period (2016-2020) , about 13 million tons of food had been saved     8     (year) after production.

We cannot end hunger     9     we do not deal with the high levels of food loss and waste. Cooperation and innovations (创新) in business models, technologies and digital solutions could all contribute     10     reducing food loss and waste.

An article describing the attitude of post-1990s generations toward life has     1     ( recent ) become popular on Chinese social media. By using the phrase “ Buddha-like   youngsters ”（佛系青年）, the author     2     ( show ) that some of the post-90s generations have seen through life and kept     3     casual and calm attitude toward life. “They have become more casual and cared     4     ( little ) about life’s choices.”

“It is fine to have something or not, there is no need to fight for or win anything, and they are easy     5     ( satisfy ),” says the article. A classic example is that Buddha-like youngsters do not care about     6     ( choose ) what to eat or where to spend a holiday.

The phrase has been received well by netizens    7     it was first created. The original Wechat post has been read more than one million     8     ( time ) and then read more than 60 million on Sina Weibo till now.     9     ( it ) sudden appearance and quick popularity show that the post-90s generations are under great pressure. “ We should pay attention     10    their needs and create a suitable environment for them to develop,” says Xu Hua, professor of the School of Sociology and Political Science of Anhui University.

Charles Darwin was an English     1     (science) who studied nature. He is known     2     his theory of evolution (进化论)．

Darwin was born on February 12, 1809, in Shropshire, England. In 1831, Darwin boarded a ship     3     (call) the HMS Beagle and set out on a fantastic five­year journey around the world. His goal was     4     (study) the natural history of the areas he was to explore. Darwin was     5     (amaze) at the variety (多样性) of species he saw on his journey. He noticed that although the different islands had similar animals and plants, many seemed to have changed to adapt (适应) to their local environments. He noted some     6     (difference) between the mockingbirds found on San Cristobal, Floreana and two other islands. This led     7     (he) to wonder why they varied from place to place.

Darwin first presented his theory of evolution by natural selection (选择) in 1858 to explain how animals adapted to their environment to survive. The idea of evolution     8     (be) not new then, but Darwin’s theory explained how evolution occurred. When Darwin published On the Origin of Species in 1859, the book was     9     immediate success. However, it was not popular with people     10     believed that all the animals on the planet had been made at the same time by one creator. But Darwin scientifically proved all the species on Earth had evolved from earlier species!
