Play allows children to use their creativity while developing their imagination and physical, cognitive（认知的）, and emotional strength. Play is important to healthy brain development. Play allows children to create and explore a world they can master, conquering their fears while practicing adult roles. Undirected play allows children to learn how to work in groups, to share, to negotiate, and to resolve conflicts.

    Ideally, much of play involves adults, but when play is controlled by adults, children acquiesce（顺从）to adult rules and concerns and lose some of the benefits play offers them, particularly in developing creativity, leadership, and group skills. In contrast to passive entertainment, play builds active, healthy bodies. In fact, it has been suggested that encouraging unstructured play may be an exceptional way to increase physical activity levels in children, which is one important strategy in the resolution of the obesity problem.

    Children's development is critically influenced by appropriate, affective relationships with loving and consistent caregivers as they relate to children through play. When parents observe their children in play or join with them in child-driven play, they are given a unique opportunity to see the world from their children's vantage point as the child navigates a world perfectly created just to fit his or her needs. The interactions that occur through play tell children that parents are fully paying attention to them and help to build enduring relationships. Parents who have the opportunity to look at their children's world learn to communicate more effectively with their children aid are given another setting to offer guidance. Less verbal children may be able to express their views, giving their parents an opportunity to gain a fuller understanding of their perspective. Quite simply, play offers parents a wonderful opportunity to engage fully with their children.

    Play is essential to the academic environment. It ensures that the school setting attends to the social and emotional development of children as well as their cognitive development. It has been shown to help children adjust to the school setting and even to strengthen children's learning willingness. Social-emotional learning is best integrated（融合）with academic learning; it is concerning if some of the forces that enhance children's ability to learn are improved at the expense of others. Play and unscheduled time that allow for peer interactions are important components of social-emotional learning.

    Windbreaks are barriers (屏障) formed by trees and other plants. Farmers plant these barriers around their fields, which help prevent the loss of soil, stop the wind from blowing soil away. They also keep the wind from damaging or destroying crops. Besides, extra trees and plants can be cut down and used or sold for wood.

    Windbreaks can be highly valuable for protecting grain crops. For example, in parts of West Africa grain harvests were as much as twenty percent higher in fields protected by windbreaks compared to fields without them.

    But here is something interesting about windbreaks. They seem to work best when they allow some wind to pass through the barrier of trees or plants around a field. If not, then the movement of air close to the ground will lift the soil. Then the soil will be blown away. For this reason, a windbreak works best if it contains only 60 to 80 percent of the trees and plants that would be needed to make a solid line. An easy rule to remember is that windbreaks can protect areas up to 10 times the height of the tallest trees in the windbreak.

    There should be at least two lines in each windbreak. One line should be large trees. The second line, right next to it, can be shorter trees or other plants with leaves. Locally grown trees and plants are considered the best choices for windbreaks. Trees reduce the damaging effects of wind and rain. Their roots help protect soil from being washed away. And trees can provide animals outdoors with shade from the sun.

    A new report says living in a city makes it harder for people to concentrate(集中) on some tasks. The research found that people who live in rural areas can focus better than people in urban areas. The study is from Goldsmiths College, which is part of the University of London. Head researcher Dr. Karina Linnell and her team made great contributions. They studied how two groups of people did the same "thinking tasks". The team went to a remote(偏远的) part of Namibia, southwest Africa, to study the Himba tribe. Himba people live a very basic life in the desert. They are still doing traditional farming. The team also studied members of the same tribe who had moved to the nearest town. Dr. Linnell said the tribe who lived in the desert did much better on the tests than those in the town. It's really interesting and shocking.

    Dr. Linnell said their research may lead to changes in the way companies operate. In the future, workers may move from cities to live and work in the countryside. Linnell said there are too many things around us in the city that stop us from thinking about one thing for a long time. This means we do not work at our best. She asked, "What if, for example, companies realized certain tasks would be better carried out by employees based outside of the urban environment? There their concentration ability is better. "The past century has seen billions of people move from the countryside to big cities. In the future, the trend may not continue. If Dr. Linnell's research is true, this century might see many of those people return to the great outdoors. Let's wait to see what will happen.

    Americans with small families own a small car or a large one. If both parents are working, they usually have two cars. When the family is large, one of the cars is sold and they will buy a van (住房汽车).

    A small car can hold four persons and a large car can hold six persons but it is very crowded. A van hold seven persons easily, so a family with three children could ask their grandparents to go on a holiday travel. They could all travel together.

    Mr. Hagen and his wife had a third child last year. This made them sell their second car and buy a van. In the van, the sixth and seventh seat are used to put other things, for a family of five must carry many suitcases when they travel. When they arrive at their grandparents' home, the suitcases are removed from the two seats which can then carry the grandparents.

    Americans call vans motor homes. A motor home is always used for holidays. When a family are traveling to the mountains or to the seaside, they can live in their motor home for a few days or weeks. All the members of a big family can enjoy a happier life when they are traveling together. That is why motor homes have become very popular. In America there are many parks for motor homes.

    I was in the Sants Cruz Mountains not long ago, speaking and singing at a women's conference. We were focusing on the theme of loving others in practical ways through our gifts, and something in particular happened during one of the sessions（会议）will remain imprinted in memory.

    A young Syrian woman (Lilith) was invited to the conference at the last minute, and everyone seemed surprised and delighted that she'd actually come. Just a few days earlier, Lilith had fled her country and found refuge with one of the women attending the conference. As an Orthodox Christian in Syria, she and her loved ones had become attacked targets of violent terrorist groups in the country's ongoing civil war.

Lilith had witnessed horrors no one of her young age should ever see. Despite the further danger it presented, she'd decided to leave her home and her family to find safety here in America. Knowing some of her story, and seeing her sitting through the sessions at the retreat（畏缩不前）—head, covered in a scarf, bowed toward the floor—broke my heart.

    Lilith's story touched all of us, including Pam, who was quilt maker. Pam had just finished a beautiful quilt, and had brought it with her. She, along with a few of the leaders, decided to give it to Lilith as a symbol of their comfort and love.

During our last session, Lilith was called forward and prayed over, hugged, and wrapped up in that beautiful quilt. I thought of the many hours Pam undoubtedly spent working on it, and the terrible events that led Lilith to this moment—surrounded by the beauty and love quilt embodied. I wept. When they told her it was for her, she wept.

It was a regular school day, and the air was filled with the usual sounds of chatter and laughter as students prepared for their lessons. Little did I know that this day would soon take a dramatic turn, making it a/an 1 day.

As the bell rang, 2 the beginning of our English class, we entered the classroom, completely 3 of the coming danger. The teacher began the lesson, and we were really 4 our literature lesson when, out of nowhere, a loud fire alarm interrupted everything.

Panic spread as we understood how 5 it was. Smoke filled the hallway, and a sharp burning smell hung in the air. The neat classroom turned into a mess as everyone 6 to the door, trying to get away from the coming danger.

In all the chaos, I noticed my 7 Sarah looking obviously scared by her desk. I quickly 8 she needed help. Without hesitation, I rushed over, took her shaky hand, and told everyone to stay calm. We went through the chickening smoke together, and each 9 felt like a really long time.

As we reached the door, it felt hotter, and we knew we had to hurry. With hearts 10 , we hurried into the playground where teachers and students were making sure everyone stayed safe.

Outside, we took a moment to catch our breath, 11 by the loud sounds of approaching fire trucks. Seeing parts of the building on fire, a sense of 12 washed over us, knowing that we had made it out unharmed.

After everything happened, I couldn't help but reflect on the events of that day. 13 all this taught me it's important to stay calm when things get 14 and how helping others during hard times matters. It was a day when ordinary students became unlikely heroes, bound together by the shared 15 to overcome the unexpected challenges.
