A
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?
A. A serious food shortage.
B. Agriculture development.
C. His interest in the rice experiment.
D. His wish to plant the tallest rice in the world.
2. From the passage, we know that Yuan Longping ________.
A. developed a variety of hybrid rice
B. worked as a scientist after graduation
C. started to grow seawater rice inDubaiin 2017
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
B
If you ever get the impression that your dog can "tell" whether you look delighted or annoyed, you may be onto something. Dogs may indeed be able to distinguish between happy and angry human faces, according to a new study
Researchers trained a group of 11 dogs to distinguish between images(图像)of the same person making either a happy or an angry face. During the training stage, each dog was shown only the upper half or the lower half of the person's face. The researchers then tested the dogs' ability to distinguish between human facial expressions by showing them the other half of the person's face on images totally different from the ones used in training. The researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses more often than one would expect by random chance.
The study showed the animals had figured out how to apply what they learned about human faces during training to new faces in the testing stage. "We can rule out that the dogs simply distinguish between the pictures based on a simple cue, such as the sight of teeth," said study author Corsin Muller. "Instead, our results suggest that the successful dogs realized that a smiling mouth means the same thing as smiling eyes, and the same rule applies to an angry mouth having the same meaning as angry eyes."
"With our study, we think we can now confidently conclude that at least some dogs can distinguish human facial expressions," Muller toldLive Science.
At this point, it is not clear why dogs seem to be equipped with the ability to recognize different facial expressions in humans. "To us, the most likely explanation appears to be that the basis lies in their living with
humans, which gives them a lot of exposure to human facial expressions and this exposure has provided them with many chances to learn to distinguish between them." Muller said.
4. The new study focused on whether dogs can_________.
A. distinguish shapes
B. make sense of human faces
C. feel happy or angry
D. communicate with each other
5. What can we learn about the study from paragraph 2?
A. Researchers tested the dogs in random order.
B. Diverse methods were adopted during training.
C. Pictures used in the two stages were different
D. The dogs were photographed before the lest.
6. What is the last paragraph mainly about?
A. A suggestion for future studies.
B. A possible reason for the study findings.
C. A major limitation of the study
D. An explanation of the research method.
7. In which section is the text most likely to be found in a newspaper ?
A. Entertainment
B. Economy
C. Science
D. Nature
C
Some of the oldest art in human history is being damaged, scientists say. And climate change may be speeding up its loss. Newresearch reports that ancient rock art in Indonesian caves is degrading over time, as bits of rock slowly break off from the walls. It's a huge loss for human history.
Salt crystals（结晶）building up on the walls are a key part of the problem, the study suggests. These salt crystals go into the cave walls, changing sizes as temperatures rise and fall. This process causes the rock to slowly break down.
Salt crystals may become larger when exposed to repeated changes between wet conditions and periods of drought. These kinds of changes are expected to become more obvious as the climate continues to warm.
In particular, the researchers say, climate change may cause more intense El Nino（厄尔尼诺）events in the future. These events can strengthen the kinds of conditions that help salt crystals form Scientists are still debating the exact influence of climate change on El Nino, a natural climate cycle that drives changing patterns of warming
and cooling in thePacific Ocean.
The new study, led by Jillian Huntley, examined 11 ancient cave art sites in South Sulawesi, Indonesia. The researchers found evidence of salt formation at all 11 sites. It's merely a small part There are more than 300 known eave art sites around the region. The researchers note that salt crystals may indeed be part of the problem, adding that climate change is a growing threat, one that deserves more attention.
8. What is the main cause of the rocks breaking off from the wall?
A. Weather patterns.
B. Salt crystals.
C. Wet conditions.
D. Drought Periods.
9. Which of the following may researchers agree with?
A. El Nino events prevent salt crystals forming.
B. Climate change makes little difference to El Nino.
C.Salt crystals may become much larger in wet conditions.
D. Constant warm weather may cause salt crystals to change size.
10. Which word best describes Huntley's attitude to climate change?
A. Worried.
B. Curious.
C. Doubtful.
D. Positive.
11. What can we learn from thelast paragraph?
A. The formation and patterns of salt crystals.
B. The impact of climate change on ancient rock arts.
C. The historical value of ancient rock art in cave sites.
D. The threats of human activities to ancient eave art sites.
D
Preventing heart disease is a topic I think about all the time, given my family history of heart disease. So last summer, I travelled toBolivia.The natives, called the Tsimane, were reported to have the healthiest hearts in the world. I wanted to learn what they could teach me about preventing heart disease.
Getting to the Tsimane wasn't easy. They lived in small family groups of about 60 people along river banks. We finally found one of the villages at sunset. That night, we set up our tents in the middle of the village. Thatched huts surrounded us, with no electricity or modem conveniences.
At first, I thought they mainly got their calorics from meat. However, I found food such as rice and com made up nearly 70% of their diet. The food was not processed, lacking added sugars or salts.
During my stay there, I went hunting and fishing with the men and played soccer with the kids. I found the
Tsimane were standing or walking nearly all of their waking hours. Men spent lots of time tracking animals. Fanning and gathering, mostly done by children and women, were all-day affairs.
I also got a clear idea of how they rested. As soon as the sun went down, people returned to their huts and went to sleep. And with the call of the cock in the morning, another day began.
The lifespan of the Tsimane is actually much shorter than those living in theUS. Various factors, like animal attacks and infections, bring down the lifespan. But up until the day they die, they are often very healthy. While heart disease kills thousands of Americans every year and costs nearly a billion dollars a day, the Tsimane remind us that wealth doesn't necessarily buy health.
12. Why does the author pay so much attention to preventing heart disease?
A. He dreams of becoming a doctor.
B. He wants to teach others about the topic.
C. His family members encourage him to do so.
D. He was born with a high risk of heart disease.
13. Which factors did the author mainly focus on in his research?
A. Housing, food and cooperation.
B. Diet, activity and rest.
C. Physical work, social life and lifespan.
D. Group size, family history and consumption
14. What was the Tsimane 's sleep-wake cycle mainly based on?
A. Natural sound.
B. Routine activity.
C. Animal behaviour.
D. Natural light.
15. What might the author advise us to do after his travels inBolivia?
A. Take in less sugar and salt.
B. Stand less and walk more.
C. Eat white meat instead of red meat.
D. Live in the middle of the community.
