D Scientists have recreated a 1985 study of birds in Peru that shows climate change is pushing them from their natural environment. Thirty years ago, researchers studied more than 400 kinds of birds living on a mountainside in Peru. In 2017, researchers looked again at the bird populations. They found that almost all had moved to higher places in the mountain. Almost all had decreased in size. And, the scientists say at least eight bird groups that move to the higher altitude had died out pletely.Mark Urban, director of the Center of Biological Risk at the University of Connecticut, said this recent study was the first to prove that rising temperatures and moving to avoid them can lead to extinction.In 1985, Fitzpatrick, director of the Cornell Laboratory of Ornithology, and a team of scientists established a camp alongside a river running down a mountainside in southeastern Peru. He wanted to document where tropical bird groups lived. His team spent several weeks using nets to catch and release birds. They kept detailed notes of birds they caught, saw or heard. In 2016, Fitzpatrick passed his notes, photos and other records to Benjamin Freeman. Freeman who has been researching tropical birds for more than 10 years set out in August and September of 2017 to copy Fitzpatrick’s study. His team used the same methods, searching the same places at the same time of year.Freeman said that the birds moved an average of 98 meters further up the mountain, believing that temperature is the main cause of the birds’ movement. Fitzpatrick noted that birds used to living in areas with little temperature change might be especially at risk because of climate change. He said, “We should expect what39。A Few Active Listening Guidelines Listening is arguably the most important element of interpersonal munication. Our ability to listen well impacts the quality of all of our relationships, and not just at home with our family and friends—it can also affect our relationships and interactions on the job, as well as the effectiveness and quality of our work. 36 Instead, it is a skill that must beand practiced. Active listening means the difference between simply hearing, and listening with the intent to truly understand. It is abut important distinction.1. Give focused attention.Try to minimize external (外部的) distractions. Turn down the noise, and put down or step away from what you’re doing if possible. 37 Don’t watch the clock,or go over your todo list for later.2. 38 Direct eye contact shows your attention and intention to listen. This doesn’t mean stare, though. Be reasonable, but try not to let your eyes wander to whatever is going on around you.3. Reflect back.Restate, but don’t repeat word for word. Paraphrase what you think the other part is saying with responses such as: “What I’m hearing is…” or “Let me see if I’m following you... ” 39 4. Respond appropriately.Be open and honest in your responses. Share your thoughts, insights and feelings in a clear, but respectful and considerate manner even if you disagree.Active listening is a model for good munication. 40 It takes practice to develop active listening skills, and it’s a habit that has to be reinforced（加強(qiáng)）. Remind yourself that the goal of conversation is not merely to trade words, but to truly
