In 2021,Dr.Elodie Freymann went to Uganda to study the chimps in the Budongo Forest.As Dr.Freymann was looking through notes from other researchers,she noticed that there were several stories about chimps caring for themselves or others.She and her team decided to look through 30 years of notes from researchers who had studied chimps in the region. They also spent eight months studying two separate groups of chimps in the forest.The researchers found 34 examples of chimps treating their own injuries.Often,this sort of “self-care” was very basic,like licking(舔) an injury or cleaning themselves with leaves.Sometimes it was more complex.In some cases,Dr.Freymann says,the chimps “chew the plants up,and then apply the chewed material to the open injury.” The self-care of the chimps was interesting.But even more interesting were the seven cases they found of chimps helping out other chimps.This seems to show that chimps may be able to tell when another needs help.It’s fairly unusual for animals to try to help another injured animal.What’s really amazing is that the chimps who helped others weren’t even related. In one notable case,an adult female chewed a leaf to put on her injury.The chimp’s younger daughter saw this,and then did exactly the same thing,chewing up a leaf and putting it on her mother’s injury.What needs further research is how much of this behaviour comes from the chimps’ natural instinct(本能),and how much is learned from other chimps.As for that,not all team members agree.A team member,Ryan Black,believes such behaviour comes from instincts,but others think that it’s so complex that they’re probably learned. 1.How did Dr.Freymann and her team conduct their research? A.By carrying out experiments in labs. B.By interviewing experts in chimp behaviour. C.By following an individual chimp for long. D.By combining past records with field observations. 2.What surprised the researchers about the findings? A.The variety of plants chimps used for treatment. B.The fact that chimps helped unrelated individuals. C.The speed at which chimps learned new behaviours. D.The limited medical techniques chimps could employ. 3.What’s Black’s attitude towards the idea that the self-care behaviour is born? A.Positive.　　 B.Doubtful. C.Uncaring. D.Unclear. 4.What can be inferred from the last paragraph? A.Researchers know exactly how much of chimps’ behaviour is instinct. B.Whether chimps’ helping behaviour is instinct or learned is unclear. C.Young chimps mostly learn first aid skills through observation. D.Future research will soon solve all chimps’ behaviour mysteries. Ⅴ.七选五 (2026四川成都高二检测) In early October,Travis Gienger transported a huge pumpkin from his home in Minnesota to the World Championship Pumpkin Weigh-Off in California.His pumpkin set the record for the biggest one ever grown in North America.How do competitive growers get their pumpkins to grow to massive sizes?　1　  Gienger,who teaches horticulture(园艺学) at Anoka Technical College,begins growing his pumpkins in mid-April,starting with seeds that he grows indoors for the first few weeks,when Minnesota’s soil is too icy. 　2　 They can absorb sunlight,nutrients from the soil,and water there.“At their peak,you’re watering them with at least 600 liters a day,” he says.  Depending on the variety,pumpkin plants can grow up to a dozen fruits on a single vine(藤蔓).But to maximize size,growers remove all but one or two of these pumpkins in order to decrease each individual fruit’s competition for resources.　3　  But what exactly happens inside a pumpkin as it grows?Two factors drive natural growth:cell division and cell expansion.Cell division accounts for most of the growth at the beginning of a fruit’s life.This period lasts for about 20 days in pumpkin plants.　4　 Pumpkin cells will expand until around 50 or 60 days after pollination(授粉).  　5　 Some varieties of pumpkins have been bred specifically to maximize their size.Still,there is genetic variation even among pumpkins of the same variety.This has led to competition for the best seeds.Following each harvest,many growers auction off(拍卖掉) the seeds from their biggest pumpkins,which will then be used for the following year’s plantings.  A.Biology has the answers. B.Genetics also influences pumpkin growth. C.The following tips will give you a head start. D.When it stops,cell expansion will then take effect. E.Once it warms up,the plants are transferred outside. F.Growers extend the growth period for as long as possible. G.Growers also remove the weeds in the area for the same reason. Ⅵ.完形填空 If the plant could thrive(茁壮成长),maybe I could too,even with cancer.
