An ancient, interdependent relationship that contributes to food systems and ecosystem stability across the globe could be changing.
Many flowering plants can self-pollinate (自花传粉), or transfer pollen between their own blossoms for seed generation and reproduction, but most of these plants have relied on pollinators such as butterflies and bees to reproduce. Now — during declines reported in many pollinator populations — a new study on the evolution of one flower species' mating system has revealed a remarkable change that could worsen the challenges faced by the plants' insect partners.
The flowers reproductive evolution may be linked to environmental changes such as habitat destruction and rapid ongoing decreases in pollinator biodiversity, according to Samson Acoca-Pidolle, who led the study published December 19 in the journal New Phytologist.
Comparing seeds of wild field pansies (三色堇) collected decades ago in France with the plants' modern descendants. Acoca-Pidolle and his colleagues discovered that today's flowers are smaller and produce less nectar (花蜜) as a result of increased self-pollination, which has direct impacts on pollinator behavior.The pansies of the past self-fertilized less and attracted far more pollinators than those of the present, according to the study.
"It seems that it's only traits (特性) that are involved in plant-pollinator interaction that are evolving, " said Acoca-Pidolle. The changes could restrict the plants' ability to adapt to future environmental changes and have implications for "all of floral biodiversity" — potentially decreasing flowering plants' genetic, species and ecosystem variation.
"This may increase the pollinator decline and cause a negative feedback cycle," study coauthor Pierre-Olivier Cheptou told CNN." If plants produce less nectar, there will be less food available to pollinators, which will in turn accelerate the rate at which the animals' numbers decrease", he explained.
"The major message is that we are currently seeing the evolutionary breakdown of plant pollinators in the wild," said Cheptou, an evolutionary ecologist at the French National Centre for Scientific Research and professor at the University of Montpellier.
(1)、Which of the following may contribute to the flowers' reproductive evolution?A、Changed behaviour of pollinators. B、Severe pollution to the habitats. C、Continuing decline in pollinator biodiversity. D、Increased plant-pollinator interaction.(2)、Why were pansies in the past larger and produced more nectar?A、They self-pollinated less. B、They had a better mating system. C、They attracted less pollinators. D、They were fertilized by themselves.(3)、What is the result of the changes in the flowers' reproductive evolution?A、The flowering plants may have more variations. B、The evolution of wild plant pollinators is collapsing. C、The numbers of the animals will increase more rapidly. D、The plants will adapt to the environmental changes better.(4)、Which is the best title for the text?A、Pollinator Populations: Declining. B、Flowering Plants: Selfing. C、Interdependent Relationship: Maintaining. D、Floral Diversity: Increasing. -
2、 阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项。
Lord Norman Foster, renowned as one of the world's foremost architects, has devoted decades to redefining the concept of tall buildings. "What we've done is create a sense of identify drawn from real needs," Foster said. "It's not a fashionable idea, but generated from the realities we were in." His masterpiece includes iconic structures such as the HSBC building in Hong Kong. Now, he's set his sights on Qatar.
Currently nearing completion and set to reach a height of 301 meters, Foster's Lusail Towers are ready to claim the title of Qatar's tallest buildings. Lusail Towers are intended to serve as a center for Qatar's financial institutions, with four distinctive blocks, two standing at 70 stories and two at 50 stories.
But the construction itself wasn't all plain sailing. To address the unique challenges presented by Qatar's hot climate, Foster's team had to depart from the materials commonly used in skyscrapers in cooler countries — part of what Foster called a decades-long quest to "reinvent the tall building." The design combines advanced shading with ventilation (通风), while the towers' surfaces are coated with "marine-grade" aluminum (铝) that wraps around the buildings, protecting the glass from strong sunlight while maintaining the views and still letting in natural light. Central to the project are special shading fins (鳍), which not only optimize views and natural lighting for occupants but reduce solar radiation by 70% compared to traditional all-glass towers.
While the towers are ready to become a recognizable landmark for Lusail, Foster believes that a city's skyline reflects what lies beneath the surface. It was crucial to integrate the towers into a "low-scale master plan." They are strategically positioned on top of a subway line and at the end of a commercial avenue linking the waterfront (滨水区) to the nearby football stadium. According to Foster, the ground features of the plaza will play a significant role in the objective of transforming the area into a lively public space for the future.
(1)、According to Foster's concept, what should tall buildings be like?A、Renowned. B、Identical. C、Fashionable D、Practical.(2)、What can we learn about the Lusail Towers?A、They will function as a global financial center. B、They are expected to be Qartar's tallest building. C、They are Foster's most renowned iconic masterpiece. D、They have four blocks with the same style and height.(3)、What was the solution to the challenges caused by Qatar's hot climate?A、Coating the tower with an unconventional material. B、Reducing the views and natural lighting with shading fins. C、Replacing the glass with "marine-grade" aluminum. D、Protecting the glass from natural light and solar radiation.(4)、What's the goal of "low-scale master plan"?A、To link the waterfront to the football stadium. B、To create a remarkable plaza for the citizens. C、To offer a dynamic public space for the future. D、To connect a subway and a commercial avenue. -

18 years ago, a 14-year-old boy from Kasungu district in Malawi was forced to drop out of school for lack of fees. At the same time, a severe famine was destroying his village, claiming people's lives and leaving desperation in its wake.
This was a situation to break the strongest of minds but William Kamkwamba did not give up. Young as he was, he knew that education was where his future lay. He found hope in the library and feasted on the knowledge that he harvested from its books. It was there that he came across a science textbook entitled Using Energy. He learned that he could generate electricity using wind. The youngster realized that, if mastered, this power could help his village in exceptional ways.
Armed with determination and an iron will, the teenager set out to build a windmill out of random materials from a scrapyard (垃圾场). Though his outside world was collapsing to dust, the youngster did not hesitate about his purpose. He defended himself from all doubt and criticism. He worked tirelessly until his dream of bringing electricity to his village became reality. Soon, he was caught in the center of media attention that took him to new places that he would never have stepped on without his invention.
In his village, the dust has not settled yet and the winds of change continue to blow across the land. Windmills pump water to irrigate crops, sweeping away another period of hunger. William's former primary school boasts new and stronger buildings, thanks to the help of well-wishers and the villagers' united efforts.
What seemed like a hopeless situation has been turned into an inspirational story that motivates each and every one of us, persuading us that no misfortune is set in stone. William refused to be a school drop-out forever. He sought solutions for his problems and continued fighting even when the going got tough. He was able to rise above poverty to become a graduate from one of America's best universities, Dartmouth College.

15、 阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
Jean's dream was to be a great chef, so when she was 20, she travelled to France, which has the most famous cuisine in the world, to learn to cook. After twelve years, she was among the best.
Her father, Bob, was getting old, and she wanted to be near him. Jean accepted an offer from one of Washington's top restaurants. The manager offered her a handsome salary, and 30% ownership of the restaurant. The next day, Jean went to sign the contract. As she got out of the car, she caught sight of a green sunshade. Instead of going to meet the manager, she crossed the street towards the old restaurant, Fargonetti's. She pushed open the door and the memories came flooding back.
Jean's mum died when she was just 11, and her father lost his job and was forced to freelance (从事自由职业). Money was very short. When Jean turned thirteen, Bob had made a reservation at Fargonetti's, the capital's best restaurant.
"I'm not hungry, baby girl. I had a huge breakfast," Bob said. "This is all for you!" "Oh," Jean cried. "Daddy was so silly! He's been saving to come here for lunch for MONTHS and now he ruined his appetite with breakfast!" The waiter, Carl Bader, immediately realised what was going on and went to Mr Fargonetti, the restaurant owner, and told him about Jean and Bob.
An hour later, surprisingly, the waiter brought wonderful dishes and set them before the father and daughter. "Lunch is on the house with Mr Fargoneti's compliments (致意)," Carl said. For Bob and Jean, it was a free but magical meal. They were on cloud nine when they walked out. "Jean," said Bob happily. "I feel our luck has changed!" And it did! The next day, one of Bob's old friends called and offered him a job at a new magazine, and Jean believed Fargonetti's had made it all happen. That was when she decided to become a chef!
Twenty years later, the old restaurant looked run-down and sad, but Jean recognised the waiter immediately. "Carl?" she asked delightedly.

Tips for you to overcome comparison
Identify your triggers (诱因) and avoid them. To stop comparing yourself to others, pay attention to the people or events that cause your behavior. Do you feel discontent with your life after looking at luxury goods?. Write down your comparative thoughts as soon as they happen so you can limit your exposure to these situations or avoid them altogether.
When you minimize your abilities, it becomes easier to compare yourself to others. To avoid this negative behavior, make a list of your strengths and talents. By acknowledging your best qualities, you can learn to love yourself.
Keep a gratitude journal. To start journaling, reflect on the little things that bring you joy and write down why you're grateful for them. Keeping a gratitude journal can increase your chances of overcoming comparison, but you may forget about it if you have a busy schedule.
Work on improving your abilities. Instead of focusing on your "weaknesses", reflect on the areas you can improve. Besides,don't be afraid to ask other people for help along the way. By prioritizing yourself, you can boost your self-confidence and find your place and value.
Appreciate others instead of envying them. If you have friends who are highly achieving people, you might consider that their networks are full of people who might be able to help you become more successful in your life. Instead of envying their success, be supportive and use their success to your advantage.
A. Write down your positive qualities.
B. Do you set goals to achieve your dream?
C. Consider the advantage that others can bring you.
D. Recognize everyone's circumstances are entirely unique.
E. Take classes or workshops to develop your skills and techniques.
F. Is there someone who constantly makes you feel bad about yourself?
G. Set a reminder to write at least once a week so you can actively express appreciation.

20、 阅读下列短文,从每题所给的A、B、C和D四个选项中,选出最佳选项
When colds and flu hit, many people automatically turn to over-the-counter (OTC) medicines to push through and treat their symptoms (症状). Although these medicines are easily accessible and widely used, it might come as a surprise to many people to learn that they are not risk-free. A study estimated that every year, over 26,000 people went to the emergency room for adverse (有害的) events related to OTC cold and cough medicines.
When two or more drugs are used together, their interaction can sometimes produce unexpected harmful effects. Physicians are typically knowledgeable about potential drug interactions, so it is very important for patients to ask their healthcare providers which OTC medicines are safe for them to use.
It is important to read the package ingredients of OTC medicines closely to avoid duplication of doses (剂量重复). Cold medicines are typically made up of multiple ingredients, including pain relievers, nasal decongestants and cough suppressants or expectorants. A person who takes a single-ingredient medicine paired with one of these multi-ingredient medicines can receive an unsafe dose of that ingredient.
While everyone could potentially experience adverse effects from cold and flu medicines, some groups-including older adults, children and pregnant women-may be at greater risk.
Older people who are using prescribed (处方的) drugs to treat multiple health conditions may have a higher risk of drug interactions because of the higher number of medicines being used at the same time to treat different conditions. The aging body is not expert at absorbing, distributing and clearing medicines as younger bodies are. This can put older adults at higher risk for an overdose and drug-to-drug interactions with some medicines.
The Food and Drug Administration and the Centers for Disease Control and Prevention do not recommend giving cold medicine to children under age 4. Because of a variety of factors, young children have a higher risk of an accidental overdose and adverse events that could lead to death.
(1)、Why did the author mention the study in paragraph 1?A、To stress the easy access to OTC medicines. B、To explain the dangers of using OTC medicines. C、To emphasize the importance of OTC medicines. D、To prove the potential risks of using OTC medicines.(2)、What advice does the author give to those who take different drugs at the same time?A、Turn to doctors for advice. B、Buy medicines from physicians. C、Take only one drug instead. D、Change the ingredients of drugs.(3)、What can we infer from the text?A、Women cannot face aging positively. B、Children are more easily affected by diseases. C、Older people's body cannot deal with medicines easily. D、People's desire for health makes them take more medicine.(4)、What is a suitable title for the text?A、OTC medicines may not be safe. B、Tips for taking over-the-counter drugs. C、How to deal with an OTC drug overdose? D、Should medicines be available "over the counter"?
