The Duanwu Festival in China, also called Dragon Boat Festival, is celebrated on the fifth day of the fifth month every year according to the Chinese lunar calendar. For thousands of years, this festival has been marked by people's eating Zongzi and racing dragon boats. (A) To hold the dragon boat races is in memory of Qu Yuan. He was one of the greatest poets in ancient China.

    Qu Yuan was born in Zigui of Hubei Province over 2,200 years ago. Qu Yuan was an honest minister (大臣) of the State of Chu during the Warring States Period (475—22l BC) . He was upright, patriotic (爱国的) and wise. (B) 屈原想给自己的祖国带来和平并让它变得更强大。But the country was in the hands of bad officials, he could do nothing to change it. (C) He was very discouraged. At last, Qu Yuan ended his life by throwing himself into the Miluo River. It is said that people tried to save him by jumping into the river. But it was too late and all their efforts were in vain. Also, they were so sad and they threw rice into the water to feed Qu Yuan's spirit.

    Now we read his poem Li Sao which is filled with deep love for his country. We can see the dragon boat races and have a kind of Chinese food named Zongzi to eat during the Dragon boat Festival.

Think about the colors of fruit and vegetables: the red of tomatoes, the orange of carrots, and the purple of grapes.

You can eat fruit and vegetables of all colors—green, yellow, blue, purple and white. Each color is important to our health. These colors work together for our bodies.

Red gives us a healthy heart. Red helps improve our memory (记忆力). Yellow is good for our eyes. White can reduce (降低) cholesterol. Green is good for our eyes, too. It also gives us strong bones and teeth. Blue helps us keep a good memory as we grow old. It also helps our heart. So when you are buying or eating fruit and vegetables, remember to try fruit and vegetables of different colors.

● Earthworms are doing their part

Do you know that earthworms (蚯蚓) help to make healthy soil? Many scientists think they play a {#blank#}1{#/blank#} role in growing our food. New research has found that the animals help grow 65% of the world's rice. They make themselves one of the world's greatest rice {#blank#}2{#/blank#}.

How do the earthworms have the {#blank#}3{#/blank#} on soil? Worms make soil healthier by eating dead plants. As they eat the plants, they make something other plants need in order to grow. Worms also help soil keep water, and their movements {#blank#}4{#/blank#} tunnels that help plants grow roots. 

However, some scientists believe other living things in the soil can also do the similar things as the earthworms. They think more research is needed. 

● Wild elephants can solve puzzles

Recently scientists have found that wild elephants can solve puzzles with no training after the elephants in zoos were seen {#blank#}5{#/blank#} solving problems. 

Researchers at a wildlife area in Thailand set up puzzle boxes with three compartments (间隔). Each compartment was filled with jackfruit and opened in a {#blank#}6{#/blank#} way. By using cameras, the scientists watched 77 Asian elephants to see what they would do. By the end of the {#blank#}7{#/blank#}, they found that 11 elephants were able to get the fruit from one compartment, eight got into two compartments, and five solved all three puzzles to get the treats. 

Elephants that returned to try the boxes several times had the most success. Researchers say the ability to solve problems can help the animals {#blank#}8{#/blank#} in changing environments. And understanding how they do this could help scientists protect them in a better way.

Drinking tea is an important part of Chinese culture. {#blank#}1{#/blank#}. The most common types of Chinese tea are as follows.

{#blank#}2{#/blank#}. It has a pale color and a sharp flavor (口味). It is produced mainly in Anhui and Zhejiang. The most popular green tea is Longjing Tea, which is produced near West Lake, Hangzhou.

Red Tea (Black Tea) is the second most popular type of Chinese tea. It can help treat stomachaches. {#blank#}3{#/blank#}. 

Wulong Tea, also known as blue tea, has the advantages(优点) of green and red teas. It has a gentle flavor and can help people lose weight. Tie Guanyin Tea in Anhui and Dongding Wulong Tea in Taiwan are two well-known types of it.

Scented Tea (花茶) is created by mixing tea leaves with flowers.{#blank#}4{#/blank#}. Iasmine (茉莉) tea is the most popular of this kind.

{#blank#}5{#/blank#}

Drink it hot.

Don't drink too much strong tea.

The best time to drink tea is between meals.

Drink tea a couple of hours after taking medicine.

Green tea is the best choice for office workers.

We all enjoy the colors of autumn leaves. Did you ever wonder how and why a leaf changes color?Where do the yellows and oranges come from?To answer those questions，we first have to understand what leaves are and what they do. 

Leaves are the world's food factories. Plants take water from the ground through their roots and take CO2 from the air. Plants use sunlight to turn water and CO2 into glucose（葡萄糖），a kind of sugar. Plants use it as food for energy and growing. 

A chemical called "chlorophyll（叶绿素）" in the leaves gives plants their green color. As summer ends and autumn comes，the days get shorter and shorter，and trees "know" it's time to begin getting ready for winter. 

During winter，there is not enough sunlight or water. Trees rest during this time and live on the food they store during the summer. They begin to shut down their foodmaking factories. As the green chlorophyll disappears from the leaves，we begin to see yellow and orange leaves. 

The bright reds and purples we see in leaves are made mostly in autumn. In some trees，like maples（枫树），sunlight and the cool nights of autumn turn the glucose in the leaves into a red color. And we can enjoy the beautiful red leaves during autumn. 

The 19th Asian Games was held from September 23rd to October 8th in Hangzhou，Zhejiang province. During 15 days，players competed for 483 gold medals. There were 40 sports and 61 events. Esports（电竞） and breakdancing（霹雳舞） joined the Games for the first time. 

The Hangzhou Asian Games was a"green"and"smart"Games. There were no fireworks（烟花） let off in the city in the Opening Ceremony（开幕式）. It started from the Kongming lanterns at the beginning to the digital fireworks and digital torchbearer（火炬手） in the end. It shows that in the digital era，the technology （技术） in China becomes stronger and stronger.
