A new study has found that North American migratory(迁徏的) birds have been getting smaller over the past 40 years. Researchers say the finding suggests a warming climate(气候)could be affecting bird growth in North America -- and across the world.
The study was recently published in Ecology Letters. Researchers measured(测量)the size of 80,000 birds killed from 1978 to 2016 during the spring and fall migrations in the city of Chicago, Illinois. Over the 40-year period, body size decreased in all 52 species. The average body weight fell by 2.6 percent. Leg bone length dropped by 2.4 percent. The one area of growth was the wingspan, which increased by 1.3 percent.
The researchers said the wing growth likely happened to allow the birds to continue making long migrations with smaller bodies. The study considered a principle known as Bergmann’s rule, in which individuals within a species grow smaller in warmer areas and grow larger in colder ones.
Brian Weeks, a biologist at the University of Michigan’s School for Environment and Sustainability, helped lead the research. He said that he believes the results show a clear connection between a warming climate and the growth of the birds. “In other words, climate change seems to be changing both the size and shape of these species,” he said.
The study found a direct connection between the average summer temperature and the body size of the birds. Dave Willard works with Chicago’s Field Museum, which was in charge of measuring all the birds. He said nearly “everyone agrees that the climate is warming, but examples of just how that is affecting the natural world are only now coming to light.”
“We had good reason to expect that increasing temperatures would lead to reductions in body size, based on earlier studies,” Weeks said. “I was incredibly surprised that all of these species are responding in such similar ways.”
The researchers plan to continue studying the Field Museum data in an effort to find additional evidence to support their findings. They will also further examine the idea that an individual’s physical development can change to fit changing environmental conditions.

Other people may have their own ideas about our lives. We can value their advice, but we don’t have to take it to heart.
Our parents have dreams for us. They want us to do well in school and to do whatever is necessary to reach our highest potential (潜力). Later in life, friends may try to set us up with their ideas of the perfect partner or the perfect job. People close to us may have ideas about how we should live our lives, ideas that usually come from love and the desire for us to be happy. Other times, they come from a place of need within them whether it is a parent who wants us to live out his or her dreams or a friend who wants us to play a good role. Whatever the case, we can appreciate and consider those people’s advice, but ultimately we must follow our own guidance.
There may come a time when all the suggestions can become overbearing (专横的). We may feel that the people we love don’t agree on our judgment, which can hurt our feelings. It can affect the choices we make for our lives by making us doubt ourselves before we’ve had a chance to decide what we want. We can tell our loved ones how much we appreciate their thoughts and ideas, but that we need to live our own lives and make our own decisions. We can explain that they need to let us learn from our own experiences. When they see that we are happy with our lives and the path we are taking to reach our goals, they can make sure that all we need them to do is to share in our joy.
1.People close to us often tell us ideas to show their ________.
A. power B. concern C. potential D. happiness

Is youth lingo ruining the Chinese language?
Young people often create their own language that goes beyond rigid linguistic rules. This year's latest slang （俚语） terms add a further simplification: the use of pinyin acronyms （首字母缩略词）. “Awsl,” in pinyin, for instance,means “Ah, wo si le” （Oh, I'm gonna die）, and is used if something is too cute or adorable to bear. “Pyq” stands for “pengyou quan”，the social feed on the popular Chinese social media app WeChat, and “nsdd” stands for “ni shuo de dui” （you're right）.
Teens want to be different from their parents, so it's natural for them to create and use their own linguistic terms to show that. In doing so, young people are indeed driving linguistic change. They aren't the only factor influencing language development, but they can indeed transform how future generations communicate.
Critics fear that Chinese internet slang will have the potential to negatively influence broader linguistic trends of Mandarin Chinese, in particular, the gradual taking over of pinyin. As pinyin gets widely used when texting or writing on mobile phone or computer, while less and less people write characters by hand, people gradually forget how to write them. The phenomenon has got a name in China: Character amnesia （健忘症）

The things we can really learn from books
It's believed that everything you need to know you can find in a book. People have always received life-guiding wisdom from certain types of non-fiction, often from "self- help” books. But actually all sorts of books can carry this kind of wisdom. A random sentence in a thriller will give you unexpected insight.
It is also believed that there is no book so bad that you can't find something of interest in it. That, actually, is a paraphrase （释义）from the Roman lawyer Pliny the Younger, a viewpoint later adopted by Miguel de Cervantes in Don Quixote. Admittedly, neither Pliny nor Cervantes were subject to some of the weakest “sex and shopping” books from the 1980s, but people still think it mostly holds true. You can learn something from the very worst books—even if it is just how crass （粗鲁的）and base9 or boring and petty （琐碎的），or cruel and intolerant the human race can be.
There is a proud tradition of extracting （摘录）lines from poetry and songs and using them in this way. But not everyone is a fan of cherry-picking odd passages from random books and using them to direct your life. Some people argue that lines from novels and plays are dependent on what surrounds them—that it's improper and self-serving to grab the odd line here and there. Others don't buy this. It ignores the way that your brain collects, refracts^ sorts and combines information. We can find meaning in everything—— and everything is fair game.
We overschedule our days and complain constantly about being too busy; we keep up with hundreds of acquaintances but rarely see our best friends; we bombard ourselves with video clips and emails and instant messages; we even interrupt our interruptions.
Books are uniquely suited to helping us change our relationship to the rhythms and habits of daily life in this world. We can't interrupt them; we can only interrupt ourselves while reading them. They speak to us, thoughtfully^ one at a time. They demand attention —they demand that we briefly put aside our work at hand and listen to someone else. You can rant (咆哮)against a book, scribble (涂鸦)in the margin, or even throw it out the window. Still, you won't change the words on the page.
We all ask each other a lot of questions: "How did you sleep?” “Where did you go on your holidays?” But there’ s one question we should ask of one another a lot more often, and that is: "What are you reading?n When we ask one another that, we sometimes discover the ways we are similar; sometimes the ways that we are different. “What are you reading?”isn’t a simple question when asked with genuine curiosity; it' s really a way of finding out, “Who are you now and who are you becoming?
