I wasalways an enthusiastic reader, sometimes reading up to three books a day as a child. Stories were like air to me and while other kids played ball or went to parties, I lived out adventures through the books I checked out from the library.My first job was working at the Ukiah Library when I was 16 years old. It was a dream job and I did everything from shelving books to reading to the children for story time.As I grew older and became a mother, the library took on a new place and an added meaning in my life. I had several children and books were our main source(来源) of entertainment.It was a big deal for us to load up and go to the local library, where my kids could pick out books to read or books they wanted me to read to them.I always read, using different voices, as though I were acting out the stories with my voiceand they loved it !It was a special time to bond with my children and it filled them with the wonderment of books .Now, I see my children taking their children to the library and I love that the excitement of going to the library lives on form generation to generation.As a novelist, l've found a new relationship with libraries. I encourage readers to go to their local library when they can't afford to purchase a book. I see libraries as a safe haven(避风港) for readers and writers, a bridge that helps put together a reader with a book. Libraries, in their own way, help fight book piracy（盗版行为) and I think all writers should support libraries in a significant way when they can.

Why do we often assume thatmore is more when it es to kids and their belongings? The good news is that I can help my own kids learn earlier than I did how to live more with less.I found the preholidays a good time to encourage young children to donate lessused things, and it worked. Because of our efforts, our daughter Georgia did decide to donate a large bag of toys to a little girl whose mother was unable to pay for her holiday due to illness. She chose to sell a few larger objects that were less often used when we promised to put the money into her school fund(基金)(our kindergarten daughter is serious about being a doctor)For weeks, I've been thinking of bigger, deeper questions: How do we make it a habit for them? And how do we train ourselves to help them live with, need, and use less? Yesterday, I sat with my son, Shepherd, determined to test my own theory on this. I decided to play with him with only one toy for as long as it would keep his interest. I expected that one toy would keep his attention for about five minutes, ten minutes, max. I chose a red rubber ballsimple, universally available. We passed it, he tried to put it in his mouth, he tried bouncing it, rolling it, sitting on it, throwing it. It was totally, pletely enough for him. Before I knew it an hour had passed and it was time to move on to lunch.We both became absorbed in the simplicity of playing together. He had my full attention and I had his.

It's more likely that none of us start a conversation because it's challenging, or we think it's unnecessary. But the next time you find yourself among strangers, consider that small talk is worth the trouble. Experts say it's an invaluable social practice that results in big advantages. Small talk is the grease (润滑剂) for social munication, says Bernardo Carducci, director of the Shyness Research Institute at Indiana University Southeast. Almost every great love story and each big business deal begins with small talk," he explains. "The key to successful small talk is learning how to connect with others, not just municate with them."In a 2014 study, Elizabeth Dunn, professor of psychology at UBC, invited people on their way into a coffee shop. One group was asked to look for an interaction (互动) with its waiter; the other, to speak only when necessary. The results showed that those who chatted with their waiter reported higher positive (积极的) feelings and a better coffee shop experience. "It's not that talking to the waiter is better than talking to your husband." says Dunn. But interactions with peripheral (边缘的) members of our social network matter for our wellbeing also."Dunn believes that people who reach out to strangers feel a greater sense of belonging (归属感), a relationship with others. Carducci believes developing such a sense of belonging starts with small talk. "Small talk is the basis of good manners." he says [2018II卷D篇]通过每段的首尾句或第二句及转折处句子找出观点结论性的词句We've all been there: in a lift, in line at the bank or on an airplane, around by people who are, like us, deeply look at their smartphones or, worse, fighting with the unfortable silence.首段只是一个铺垫而第二段but转折词后面信息才是关键信息，Small talk是在文中反复出现的高频词文章结构属于总分结构：铺垫+总观点+分别解释科普类文章的一大特点提出一个现象或问题再提出观点结论然后进行解释说明首先就可以排除A和C 那么B和D 那个和主旨更切合呢B和D结构相同都是of结构显然D文中并没有提到ways，而是反复在讲advantages第4篇We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes(基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to living at high altitudes. Cattle raising people in East Africa and northern Europe have gained a mutation(突变) that helps them digest milk as adults.Oh Thursday in an article published in Cell, a team of researchers reported a new kind of adaptation not to air or to food, but to the ocean. A group of seadwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, they've also built houses on stilts(支柱) in coastal waters. "They are simply a stranger to the land," said Redney C. Jubilado, a University of Hawaii researcher who studies the Bajau.Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. "We were so amazed that they could stay underwater much longer than us local islanders," Dr. Jubilado said. I could see them actually walking under the sea.' In 2015, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them. "It seemed like the perfect chance for natural selection to act on a population," said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.

The microorganisms(微生物) from our bodies grow uncontrollably on surfaces of the International Space Station, so astronauts spend hours cleaning them up each week. How is NASA overing this very tiny big problem? lt's turning to a bunch of high school kids. But not just any kids. It depending on NASA HUNCH high school class, like the one science teachers Gene Gordon and Donna Himmelberg lead at Fairport High School in Fairport, New York.HUNCH is designed to connect high school classrooms with NASA engineers. For the past two years, Gordon's students have been studying ways to kill bacteria in zero gravity, and they think they're close to a solution(解决方案). "We don't give the students any breaks. They have to do it just like NASA engineers," says Florence Gold, a project manager."There are no tests," Gordon says. "There is no graded homework. There almost are no grades, other than 'Are you working towards your goal?' Basically, it's 'I've got to produce this product and then, at the end of year, present it to NASA.' Engineers e and really do an inperson review, and..it's not a very nice thing at time. It's a hard business review of your product.Gordon says the HUNCH program has an impact(影响) on college admissions and practical life skills. "These kids are so absorbed in their studies that I just sit back. I don't teach." And that annoying bacteria? Gordon says his students are emailing daily with NASA engineers about the problem, readying a workable solution to test in space. （2019全国IlI卷D篇）快速扫读每段的首尾句或第二句及转折处句子寻找观点结论Bacteria are an annoying problem for astronauts.
