The study involved a two-week experiment where participants were asked to record how nature they came across in their daily routine made them feel. They took a photo of an item that caught their attention and take down about their feelings in response to it. Other participants tracked their reactions to human-made objects, took a photo and write down theirfeelings, while a nother group did neither.Examples of nature could be anything not human built: A house plant, a dandelion（蒲公英）growing in a crack in a sidewalk, birds, or sun through a window. “This wasn’t about spending hours outdoors or going for long walks in the wilderness,” Passmore says. “This is about the tree at a bus stop in the middle of a city and the positive effect that one tree can have on people.”Passmore reports she was “overwhelmed” not only by the response of her 395 study participants, who submitted more than 2,500 photos and descriptions of emotions, but also by the impact that simply noticing emotional responses to nearby nature had on personal well-being. It also had an impact on their prosocial orientation（亲社会倾向）, which is a willingness to share resources and the value they placed on community, she discovered.“The difference in participants’ well-being — their happiness, sense of elevation, and their level of connectedness to other people, not just nature — was significantly higher than participants in the group noticing how human-built objects made them feel and the control group,” she said.1. Which of the following objects may have the strongest positive effect on human well-beings?A. pictures of flowers on the wall.B. Wild animals shown in the video.C. A wild flower in a street corner.D. large bunch of artificial flowers in the office.2. How many group of people were asked to participate in the study?A. twoB. threeC. fourD. five3. According to the passage, who is the most suitable for volunteer work?A. People who often noticing the nature.B. People who always do the housework.C. People who often notice human-made objects.D. People who love doing exercise in the park.4. Where is the passage probably taken from?A. A news report.B. A science fiction.C. A medical report.D.
