Something happens to many children when they are out of school over the summer months. It is called the “summer slide.” This may sound like a ride at a water park. But it's not. Summer slide is when children forget much of what they learned during the latest school year.

    To fight the effects of summer slide, teachers often give students homework over the summer. Many parents may send children to all kinds of camps or find other activities to keep them learning. Some even try to build up their children's strengths by getting them into extra tutoring.

    However, experts say keeping children busy all the time is not good for them. The result is often a tired child with an overcrowded schedule. This keeps a child's brain active constantly—learning, gathering information and preparing for the next event. And this may have the opposite effect the parents are not hoping for.

    What should parents do instead? Nothing. According to Lea Waters, a psychologist specializing in positive psychology and positive education, slowing down actually helps children become the best they can be. Machines need to be reset, while kids need to goof off（偷懒）. She says that goofing off really allows kids to have some downtime, when they're not focused on a specific task but are free to do something that they're interested in doing and that they can do more automatically and get enjoyment from, like shooting baskets or listening to the music.

    She also adds that goofing off does not mean the brain isn't working. It just goes into this default network mode（默认网络模式）and uses that time to process all the information it had during the day, to integrate（整合）new information. It makes a kind of decision about what information to put into memory and what to get rid of, which in fact helps to improve memory.

Sport Tourism

    Tourism is the world's largest industry and is predicted to grow well into the years to come. Increasingly, the economic importance of tourism has been recognized by governments around the world. At the same time, the tourism industry has become more complicated in its development and marketing new forms of tourism. One of the fastest growing parts of the tourism industry is travel related to sport and physical activity. A recent survey found that while the traditional beach and sight-seeing vacations continue to predominate, 22% of those surveyed reported that opportunities to participate in sports were important when selecting a vacation.

    The term sport tourism has been adopted in recent years to describe sport-related leisure travel. It is generally recognized that three are three broad categories of sport tourism. The first category. Watching sporting events or Sports Event Tourism includes hallmark events such as FIFA World Cup Football Championships, and the Olympic games. Tournament sponsored by the Professional Golf Association or the World Tennis Association are also part of the spectator-centered sector of sport tourism.

    The second type of sport tourism, celebrity and nostalgia sport tourism involves visiting famous sports-related attractions. Visits of the sports halls of fame fall into this category. Another form of celebrity and nostalgia sport tourism that has emerged in recent years is meeting famous sports personalities. The cruise industry has been experienced in this area. Sports theme cruise such as “the NBA basketball cruise” arrange for passengers to meet personalities from sports while on board.

    Active participation is the third category of sports tourism. This is composed of individuals who travel to participate in golf, skiing, and tennis in particular, although other sports such as fishing, and scuba diving are popular in the US.

    After study for hours, I went outside and up to the roof nearby for a break and watched people swimming in the sea. It was a sunny day—a blue, cloudless sky over a calm sea. But then, as I looked in the distance. I discovered a series of three or four big waves heading towards the shore. I'd seen these mini-tsunamis (小型海啸)many times before. They were heading at speed in the direction of the swimming area. Most people knew to look out for them, but from the screams that started coming from the beach, I could tell someone was in trouble.

    Without thinking, I ran down into the street, holding my bodyboard (冲浪板)on the way and shouted at a stranger to call the coastguard(海岸警卫). My neighbor Tom had heard the screaming as well and was also outside with his bodyboard, so together we rushed to the steps that led down to the sea.

    Once we got closer, we discovered the waves had pulled a boy and a girl into the open sea. I knew that the nearest boat would take at least 30 minutes to reach us. I wasn't used to this sort of emergency—I'd never been trained as a lifeguard—but I didn't think twice about trying to save them.

    I suppose in a way I wanted to impress everyone; at 19, a deal like that can seem like a good opportunity to show off.

    Tom and I dived into the water and it took us 10 minutes to get to them. When we finally reached them, they were almost lifeless with only their heads coming in and out of the water. We could tell they were still alive from their small breaths but it was clear they wouldn't have been able to stay there much longer. I held the boy and pulled him over my board. Tom then moved the girl onto his board.

Paragraph 1:

    We discussed pushing them back to the shore, but we were too far out.

Paragraph 2:

    That night, word came from the hospital that the two kids were in good condition.

    What is eco-fashion? Eco-fashion is about making clothes that considers the environment, the health of consumers and the working conditions of people in the fashion industry.

    A closer look at the fashion industry points out many problems that are common practices in the creation of our fashions from the field to the factory. Firstly, the production of textiles pollutes the environment heavily. Cotton-planting uses pesticides; sheep-farming and wool-cleaning bring about global warming. Secondly, every stage of clothing production consumes a great deal of energy and some also involve chemicals which obviously do harm to the surroundings. In addition, there is a lot of waste produced in the process, especially in the form of polluted water. Thirdly, growing purchasing power and our shopping habits further worsen the bad effects. We are now buying clothes in increasing quantities and we are also quick to throw away clothes that have been worn only a couple of times.

    Then, how to solve the problem? To a large degree, it is the fashion producers that really have the power and the responsibility to shape our future. There are a great many ways these producers can reduce their ecological footprint, from switching to green energy and reducing energy use, through selecting sustainable materials and choosing local suppliers, to recycling and minimizing waste. On the other hand, as consumers we can all play our part by selecting environmentally friendly clothing and reducing clothing buying.

    There is some concern that eco-friendly fashions are just a trend that we will eventually grow tired of but we can make sure that doesn't happen. Now many people are beginning to shop for organic food products because the benefits of eating food free of chemicals are immediate. They relate directly to our personal health. In fact, choosing eco-fashion can also do good to our personal health, though it is mostly done by way of keeping the health of the planet.

    Why do earthquakes happen? Scientists believe that the surface of the earth is covered by a number of moving plates. Sometimes two plates move towards and push against each other. Sometimes they stop for years but at other times they jump and an earthquake is felt. Because of the movements of these plates, California, China and Japan have a lot of earthquakes. You can see the result in San Francisco where the Pacific plate meets the North American plate. When the 1906 earthquake happened, the Pacific plate jumped 5 to 6 metres to the north.

    China is a country where many earthquakes happen. The Pacific plate is pushing China from the east and the Indian plate is pushing China from the southwest. The power of this movement created the Himalayas and Mount Qomolongma. It now causes earthquakes in China. We cannot stop earthquakes but we can do things to make sure they do not destroy whole cities. First it is not a good idea to build houses along the line where two plates meet. Second, if you think there may be an earthquake, make sure to build houses on rock rather than sand. Third, you must make the houses as strong as possible. Weak buildings will fall down in an earthquake, but strong ones may stay up.
