26、 Most animals living in crowded conditions have particularly strong immune systems, so it long puzzled researchers that honeybees do not.
Part of the answer, discovered in 2015, is that queen bees vaccinate their eggs by moving parts of proteins from disease-causing pathogens to them before they are laid. These act as antigens to trigger the development of a protective immune response in the developing young. But that observation raises the question of how the queen receives her antigen supply in the first place? Dr. Harwood wondered if the nurse bees were taking in parts of pathogens and passing them to royal jelly they were producing while eating the food brought to the hive.
To test this idea, he teamed up with a group at the University of Helsinki, in Finland, led by Dr Heli Salmela. Together, they collected about 150 nurse bees and divided them among six queenless mini hives equipped with baby bees to look after. Instead of honey, they fed the nurses on sugar water, and for three of the hives they added P. larvae, a bacterium causing a hive-killing disease, to the sugar water.
In this case, to stop such an infection happening, Dr Harwood and Dr Salmela heat-treated the pathogens and so killed them in advance. They also labelled the dead bacteria with a fluorescent dye, to track them easily. And, sure enough, it was confirmed that parts of P. larvae were getting into royal jelly released by those bees which had been fed with the sugar water containing that.
All told, these findings suggest that nurse bees are indeed, through their royal jelly, passing antigens onto the queen for vaccinating her eggs. They also mean the nurses are vaccinating baby bees as well, because baby bees, too, receive royal jelly for the first few days after they come out.
【1】What does the underlined word “trigger" in Paragraph 2 probably mean?
A．Cut out.
B．Set off.
C．Slow down.
D．Put off.
【2】Which is the main experimental subject in Paragraph 3?
A．Queen bees.
B．Nurse bees.
C．Bee eggs.
D．Baby bees.
【3】Why was P. larvae added to the sugar water?
A．To test if it would cause a hive-killing disease.
B．To check how the bacterium would affect the hive.
C．To see whether the target bees would favor the taste.
D．To confirm the bees would pass pathogens to royal jelly.
【4】What is the text mainly about?
A．How bees multiply.
B．How antigens function.
C．How bees get vaccinated.

27、It was an extremely hot day. My younger brother Walt and I had decided to go swimming in a deep swimming hole across Mr.Blickez’s farm and through some woods，because it would be the only way to cool us down.
The only problem with our plan was that this farm was guarded by a huge mean Hereford bull（公牛） named Elsie. Mr. Blickez had told us that Elsie was the meanest bull in town, maybe even in the county and we believed in him. But the hotter it got，the more we thought there was something fishy about what he said. For one thing，we remembered Mr. Blickez liked telling tall tales; for another，Elsie seemed like a strange name for a bull. Finally，I talked Mom into asking permission for us to walk across the farm，and Mr. Blickez agreed.
On our way across the farm，we stopped at the fence to admire the swimming hole. The sun shone brightly on the cool water. We couldn’t wait to get there. Suddenly，Walt shouted loudly. Elsie had run to him and was licking（舔）his back. I immediately hid behind the fence. However，when I looked up，I saw that Elsie wasn’t a big mean bull at all. She was licking my brothers back as long as he stood still.
When we discovered the truth，we were so happy. We then ran to the swimming hole and jumped in. The water was just as cool as we had dreamed. After that day，we had many good days and we often visited our secret swimming hole guarded by the so-called“big mean bull”.

28、A bike repairer at Beijing’s Peking University has won respect from many for remaining dedicated to his work over the course of the past 16 years. Lin Qinggang, from Xingtai city, north China’s Hebei Province, started his business in 2006. Before that point, he had been a migrant worker at a construction site and a bicycle salesman in Beijing. In 2017. Peking University built a repair shop for Lin, which had been transformed from a 32-square-meter container. Lin tells people that he starts work at 8:30 a. m, but that for most of the time, he’s available as early as 8 a.m.
Because students always come over to Lin’s shop to have their bicycles repaired before and after lunch and dinner breaks, the man is often busy during these hours. This means he has to finish his meals quickly.
“During the busiest time before the COVID-19 pandemic hit, I never had lunch on time, usually having supper at about 8 or 9 p.m., and sometimes even at 10 p.m.,” Lin recalled, saying that he once repaired 180 bicycles on his busiest day.
Lin’s services has won recognition from teachers and students at Peking University, who would often share food with him during holidays such as the Mid-Autumn Festival and the Dragon Boat Festival. Such gestures of goodwill have deeply touched Lin.
“Some of the services that I provided were for free, but the students insisted on giving me money or paying me extra. I think this is the way they expressed their encouragement,” Lin said.
When Lin just started the business, some young people had doubted his abilities as a bike repairer. He just worked very hard to prove himself. Eventually, most of the people changed their opinions.
Lin has repaired nearly 500,000 bicycles in 16 years. He has gained the trust of teachers and students at Peking University with all the good qualities he possesses, including his dedication and reliability.
【1】What caused Lin Qinggang’s never having lunch or supper on time?

A．He always repaired bikes for students free of charge.
B．He was deeply moved by people’s kindness.
C．Students often paid him extra money because they had sympathy for him.
D．People always believed in his abilities as a bike repairer.
【3】Which of the following best describes Lin Qinggang?
A．Dedicated and dependable.
B．Well-educated and ambitious.
C．Cheerful and creative.
D．Indifferent and selfish.

D．Because of his hard work and good qualities he possessed.
29、In recent years some extreme weather events have arisen from global warming because of human activities, with studies indicating an increasing threat from extreme weather in the future. Scientists were certain that global warming is being caused mostly by increasing concentrations of greenhouse gases and other humanactivities.
Its effects include warming global temperature, rising sea levels and expansion of deserts in the subtropics(亚热带). Warming is expected to be greater over land than over the oceans and greatest in the Arctic, with the continuing loss of glaciers, permafrost and sea ice. Other likely changes include more frequent extreme weather events including heat waves, droughts, heavy rainfall with floods, heavy snowfall and species extinction due to great change of temperature. Bad effects on humans include the threat to food security from decreasing crop yields and the loss of populated(住人的) areas because of rising sea levels.
Possible responses to global warming are reduction of emissions(排放), adaptation to its effects, building systems resilient to its effects, and possible future climate engineering. Most countries are parties to the United Nations Framework Convention on Climate Change UNFCCC), whose objective is to prevent dangerous climate change. It has adopted a range of policies designed to reduce greenhouse gas emissions and to assist in adaptation to global warming. It is agreed that future global warming should be limited to below 2.0 °C (3.6 °F) relative to the pre-industrial level.
On 12 November 2015, NASA scientists reported that human-made carbon dioxide continues to increase above levels that have not been seen in hundreds of thousands of years: currently, about half of the carbon dioxide released from the burning of fossil fuels remains in the atmosphere and is not absorbed by vegetation and the oceans.
【1】What does the underlined word “resilient” mean?
A. be easily damaged B. be able to recover easily
C. can be bent easily D. be difficult to change
【2】Which of following is NOT mentioned as an effect of global warming?
A. rising sea levelsand expansion of deserts
B. more frequent extreme weather events
C. species extinction
D. increasing crop yields
【3】Which of the following can be inferred from the last two paragraphs?
A. It is likely for us to deal with global warming by reducing greenhouse gas emissions, adapting to its effects and climate engineering.
B. There is no solution to too much carbon dioxide released into the atmosphere.
C. It is common that human-made carbon dioxide keeps on increasing greatly in the previous several centuries.
D. Future global warming should be limited to below 3.6 °C.
