A Lifelong Devotion to Keeping People Fed
Yuan Longping is a Chinese agricultural scientist and educator, known for developing the hybrid rice varieties. Yuan graduated from the Southwest Agriculture Institute in 1953 andbegan his teaching career at an agriculture school.
In the 1960s, when a serious food shortage sweptChina, Yuan decided to devote himself to studying how to increase the yields of rice. He then began a lifelong connection with rice.
Yuan succeeded in growing the world’s first high-yielding hybrid rice varieties in 1973, which could reach a yield of over 500 kg per mu (about 0.067 hectares, rising from the previous yield of only 300 kg per mu. For the next four decades, he continued to work on research and development of hybrid rice, achieving increasingly higher outputs. In 2020, hybrid rice developed by Yuan’s team achieved 1,500 kilograms per mu in two growing seasons, a new world record.
InChina, where rice is the main food for the majority of the 1.4 billion people, the planting area of hybrid rice has reached 16 million hectares, or 57 % of the total planting area of rice, helping feed an extra 80 million people a year.
Hybrid rice has also been grown in over 40 countries, including theU.S.,Brazil,India,Vietnam, thePhilippinesandMadagascar. The total planting area of the hybrid rice has reached 8 million hectares overseas.
Even after a great success, Yuan never held himself back from making new breakthroughs. In 2017, his team started to grow seawater rice inQingdao. The rice was designed to grow in saline-alkaline land and survive even after being completely in seawater. His team planned to develop a type of seawater rice that could be planted in 6.67 million hectares of saline-alkaline land acrossChinato boost the country’s rice harvest by about 20 %. In 2018, Yuan’s team was invited to plant the saline-alkaline tolerant rice in experimental fields inDubai, which achieved huge success. In June 2020, his team started to grow seawater rice on a farm at an altitude of 2,800 meters in northwestChina’sQinghaiProvince. The experiment succeeded.
Yuan had two dreams — to “enjoy the cool under the rice crops taller than men” and that hybrid rice could be grown all over the world to help solve the global food shortage.

1. What made Yuan Longping decide to study rice?

D. grew the first high-yielding hybrid rice varieties in 1953
3. We can infer from the passage that Yuan Longping’s most outstanding qualities are________. A. modest and outgoing B. honest and creative C. generous and optimistic D. responsible and devoted

Put your hand over your heart and sit very still. You may notice that the sound of your heartbeat is similar to the beat of a drum. Your heart starts beating before you are born and continues throughout your life. For this reason, the beating of a drum stands for the rhythm of life for many people around the world.
InGhana, a country inAfrica, many schools use drums instead of bells to show the beginning and ending of class. Through the drum, the children ofGhanaalso learn about their history and culture. They hear old stories passed on through the music of the drum. The stories of the drum also teach children games, rules and lessons about behavior.
For thousands of years inAfrica, drums have been used to tell stories of daily life and history. Drums told the coming of a king, the start of a war, or the birth of a child. They also allowed people to share messages. But how does a drum tell a story?
InWest Africa, the most common drum used for communication is called a “talking drum”. By making higher orlower drum sounds, the drummer can make the drum “talk”.
In many African languages, words go up and down in pitch (高音 when they are spoken, almost like a song. Depending on the pitch or tone (音调, the same sound can have many different meanings. For example, when spoken with two low tones, the African word “ilu” means “drum”. When spoken with one high and one low tone, “ilu” means “town”.
Drum language works in the same way. Just as in spoken language, the word “ilu” has different meanings depending on how it’s drummed. When “ilu” is drummed with two beats using low tones, the word means “drum”.
When “ilu” is drummed with two beats using one high and one low tone, it means “town”.
Drummers create “words” to build ideas, sentences and stories. The next time you hear a song, listen for the heartbeat within the music. Can you hear the story of the drum? 4. The first paragraph mainly tells us________. A. drums beat like our hearts B. drums have a long history C. drums are widely used in the world
D. drums are important for many people worldwide 5. From the text, we learn that inGhanadrums________.
A. are not as useful as before B. teach children a lot of things C. help bring the war to an end D. are used in class by teachers 6. The example of the African word “ilu” is used to show________. A. how a word can have different sounds B. how to speak African languages C. how a drum tells stories D. how to beat a drum
7. What would be the best title for the text?
A. Know the history of the drum B. Listen to the story of the drum C. Beat the drum of life D. Love me, love my drum

Dengue is a very painful illness spread by mosquitoes. In severe cases, dengue can even be deadly. Dengue is a serious disease affecting people in around 120 countries. It can cause high fevers, headaches, and severe pain. It’s caused by a virus spread by bites from mosquitoes. Therefore, dengue is more common in warm areas. Every year, roughly 390 million people get dengue, and as many as 25,000 die from it.
Now scientists seem to have found a way to protect humans from dengue by first protecting mosquitoes. Dengue fever is caused by a virus. Though it may seem strange to think of it this way, the mosquitoes that spread the dengue virus are also infected with it. But the virus doesn’t seem to hurt the mosquitoes.
Wolbachia is a kind of bacteria commonly found in many insects. In some insects, Wolbachia can keep some viruses fromduplicatingthemselves, which is how viruses grow inside a body. Wolbachia isn’t naturally found in mosquitoes. But by infecting these mosquitoes with Wolbachia, scientists can keep the mosquitoes from catching
the dengue virus. Even better, the young mosquitoes coming from the eggs of the infected mosquitoes also carry Wolbachia.
Researchers working with the World Mosquito Program (WMP ran a 27-month study in Yogyakarta, Indonesia. They split a 10-square-mile area up into 24 smaller areas. In half of the areas, the scientists did nothing. In the other half, they set out containers of eggs from mosquitoes that had Wolbachia. They did this every two weeks for just 4 to 6 months.
Ten months later, 80% of the mosquitoes in the treated areas carried Wolbachia. The researchers report the number of dengue cases in the treated areas was reduced by 77% and that the number of people needing hospital care for dengue dropped by 86%.
Because the results of the experiment were so good, the WHO has placed Wolbachia-infected mosquito eggs in all parts of Yogyakarta and surrounding areas. The WHO says that within a year, their efforts will protect 2.5 million people against dengue and that their efforts will be turned into a program that can be repeated worldwide. 8. What kind of disease is dengue?
A. It is likely to cause death. B. It causes no pain but fevers.
C. It happens less often in hot areas. D. It hurts both people and mosquitoes. 9. The underlined word “duplicating” in paragraph 3 most probably means “________”. A. worsening the harm of B. expanding the size of C. increasing forces of D. making copies of
10. What can be inferred about the method from the figures listed in paragraph 5?
A. Its wide use.
