Older adults with a better sense of smell may live longer than thosewho have a poor sense of smell, a new study suggests. The study was a project of researchers in theUnited Statesthat was ongoing for over 13 years. They asked nearly 2,300 men and women to identify 12 common smells. All the subjects were from 71 to 82 years of age. The researchers gave the adults scores, from 0 to as high as 12, based on how many smells they identified correctly.
During the years of follow-up investigation, over 1,200 of the subjects died. When the study was launched, none of the adults were weak. They could walk a little under half a kilometer, climb 10 steps and independently complete daily activities. In the latest findings, the researchers noted that those with a weak nose were 30 percent more likely to die than people with a good sense of smell. The findings were reported last month in the scientific publication Annals of Internal Medicine.
Honglei Chen, a doctor withMichiganStateUniversityinEast Lansing,Michigan, was the lead writer of a report on the study. He said the connection between a poor sense of smell and an increased risk of dying was limited to adults who first reported good-to-excellent health. This suggests that a poor sense of smell is an early and sensitive sign for worsening health before it is recognizable in medical tests. With a poor sense of smell, people are more likely to die of brain and heart diseases, but not of cancer or breathing disorders.
The results also suggest that a poor sense of smell may be an early warning for poor health in older age that goesbeyond dementia or other neurodegenerative(神经变性的) diseases. These often signal the beginning of a weakening of the mind or body.
4. What do you know about the study mentioned?
A. The study involved researchers from the world.
B. All the participants were of different ages.
C. The study began to be performed about 13 years ago.
D. 2 ,300 men and women were young and healthy.

A. More than 1,200 of the participants passed away.
B. Many of the subjects were found with health problems.
C. All the subjects were independent of others when walking.
D. One third of the participants had a poor smell sense.
6. What can be inferred from the last two paragraphs?
A. People with a poor sense of smell have heart disease.
B. You should be careful with your health if you smell poorly.
C. People with a poor sense of smell won't suffer from cancer.
D. Most of the elder people may have the dementia disease.
7. Which is the best title for the passage?
A. Strong Sense of Smell May Be Linked to Longer Life
B. Old People Tend to Have a Poor Sense of Smell
C. A Number of Factors Result in Longer Life
D. Being Ill Means Losing the Sense of Smell
C
Have you ever done something for someone else—knowing that your actions would solely benefit THEM and not YOU? Maybe you opened a door or donated blood or volunteered in a hospital’s ER during the pandemic. This is called a prosocial behavior. Humans engage in these types of behaviors all the time.
But a question remains in science: Are we the only species who do this? As one of out closest s, chimpanzees have long been studied for signs of this. So far, research has provided mixed results on the question.
Some studies show that chimps cooperatively hunt, share food and comfort each other. But one study came to a very different conclusion. The study used a controlled lab experiment where chimpanzees in enclosures were given two options: push a button to give food to themselves or push the button to give food to themselves AND a partner chimp. If they chose the latter, it was seen as a prosocial behavior. But the result is that chimps showed no special preferences for feeding themselves and a friend over feeding just themselves. Another study conducted by DeTroy, however, discovered a totally different result.
Compared to previous controlled lab-based experiments, the setup for DeTroy’s research was very naturalistic. “We installed a button and a fountain into the chimpanzees’ outer enclosures. When an individual pushes the
button, it releases juice from the fountain. However, since the button and fountain are approximately five meters apart, the individual pushing cannot directly drink from the fountain. And if any other chimpanzees are at the fountain when the button is pushed, they, and not the pusher, will be able to drink the juice.
In this experiment, chimpanzees showed a willingness to act in the interest of others, with individual chimpanzees prepared to push the button without benefiting themselves.
“It is really fascinating to see that many of the chimpanzees were willing to prosocially provide valuable resources to the group members even if they couldn’t benefit themselves from their behavior.” said DeTroy.
Further research may reveal what lies behind their prosocial motivation. But for now, it’s safe to assume that chimpanzees are not simply aping human behavior.
8. Which of the following belongs to prosocial behaviors?
A. Jack participated in voluntary work in the library just to earn credits.
B. Mark turned to his classmate for help when feeling stressful in study.
C. Tim guided a lost child back home on his way to an important job interview.
D. Rose often interrupted the teacher to ask questions actively in the math’s class.
9. What is the task of the chimpanzees in the lab-based study?
A. Sharing food.
B. Making a choice.
C. Comforting others.
D. Showing sympathy.
10. How is DeTroy’s study different from the previous ones?
A. It was based on controlled lab experiment.
B. It gave juice to the chimpanzees as a reward.
C. It offered the tested chimpanzees a natural surrounding.
D. It provided a chance for chimpanzees to help their partners.
11. What can we learn from DeTroy’s quotes?
A. Chimpanzees can develop abilities to help others.
B. Chimpanzees have acquired many human behaviors.
C. Chimpanzees in the wild is cleverer than those in the lab.
D. Chimpanzees displayed prosocial behaviors for certain rewards.
D
California's August Complex Fire tore through more than 1,600 square miles of forest last summer,burning nearly every tree in its path. It was the largest wildfire in the state's recorded history, breaking the record
previously set in 2018. After the fire, land managers must determine where to most efficiently plant new trees.
A predictive mapping model called the Postfire Spatial Conifer Restoration Planning Tool recently described in Ecological Applications could inform these decisions, saving time and expense. The tool can “show where young trees are needed most, where the forest isn't going to come back on its own, where we need to intervene（干预）if we want to maintain forests," says lead author Joseph Stewart, an ecologist at the University of California, Davis.
To develop the model, Stewart and his colleagues classified data collected from more than 1,200 study plots in 19 areas that burned between 2004 and 2012. They combined these data with information on rainfall, geography, climate, forest composition and bum severity.Theyalso included how many seeds sample conifer trees （针叶树）produced in 216locations over 18 years, assessing whether the trees release different numbers of seeds after a fire.
The tool's potential benefits are significant, says Kimberley Davis, a conservation scientist at theUniversityofMontana, who was not involved in the study. Those managers will still have to make hard decisions, such as which species to plant in areas that may experience warmer and drier conditions resulting from climate change, but the model provides some research-based guidance to help the forests recover.
12. What challenge do land managers face after the wildfire?
A. Lack of wood supplies.
B. Where to plant new trees best.
C. How to save the burned trees.
D. Loss of trees and wild animals.
13. What's the main idea of paragraph 2?
A. The function of the tool.
B. The disadvantages of the tool.
C. The improvement of the tool.
D. The development of the tool.
14. What does the underlined word "They" refer to?
A. The study plots.
B. The data.
C. Stewart and his colleagues.
D. The seeds.
15. What isDavis' attitude towards the tool?
A. Skeptical.
B. Ambiguous.
C. Tolerant.
D. Optimistic.

Scout could clearly remember the night she had to leave her home in Poland. It was the beginning of World War∧and her family had to escape as soon as possible. She quickly packed a suitcase with a few pieces of clothing, her diary, and her most prized treasure, a silk scarf. Scout and her best friend, Betty, had persuaded their parents to buy them matching scarves, which they took as a symbol of their friendship. Scout didn't know she was going to America and would not be returning.
Scout kept that special silk scarf for many years. One day she decided to give it to her granddaughter, Eliza, to wear to her first job interview for good luck. Scout was afraid that Eliza would lose the scarf, but the granddaughter promised, "Don't worry, Grandma. Nothing's going to happen to your scarf. You'll see that it's going to bring both of us luck." And with that, Eliza kissed her grandmother and left for the interview.
Leaving the interview, Eliza felt confident that she had got the job so she decided to celebrate by going to a restaurant. Sitting at her table, Eliza felt an elderly woman staring at her for a long time.
"I'm sorry. Do I know you？" Eliza asked.
"I'm sorry, dear, but you remind me of my best friend," the old woman replied. "She looked like you and used to wear a scarf just like yours." Eliza listened carefully, with her eyes and mouth wide open. She had heard stories of her grandmother's best friend and knew the meaning of the scarf. Could this woman be Betty, her grandmother's childhood friend?
