Writing an article for your school newspaper can be exciting and rewarding, especially when you proudly see your name in print.

    Decide on a topic. {#blank#}1{#/blank#} If you plan to write a news article for a monthly newspaper, you will need to take into consideration whether the topic will be relevant before printing. To get ideas for stories, listen to your fellow students and find out what has them talking. Follow developments within your school and community to get information on what would interest your readers.

    Do your research. There is an old saying in law that a good lawyer never asks a question that they don't know the answer to. {#blank#}2{#/blank#} To sum up, the more, the better.

    Attract the readers with a lead. As the beginning of a newspaper story, a lead has to be direct, but it does not mean you don't need to entertain the reader as well. {#blank#}3{#/blank#} Your lead must be short, but it must also state as many of the essential parts of you story as possible.

    Consider the 5 Ws and H. These are the meat and potatoes of your news articles. You article must answer all of these questions: Who, What, When, Where, Why and How. Once you have answered these things, you can feel confident. {#blank#}4{#/blank#}

    Write, edit, rewrite and repeat as necessary. So, much about having a successful final product is about being willing to spend time and effort in editing and reviewing process. {#blank#}5{#/blank#} After that, make changes as a result. Having taken some useful suggestions, you are to make your article readable not only for their content, but also for their quality.

A. Think about what is happening on campus.

B. You have effectively informed your readers.

C. Get them interested with an interesting beginning.

D. Do not be afraid to accept positive comments.

E. News articles are suitable for the date of publication.

F. Take note of anything particularly unusual.

G. Try to find out as much as you can on the subject.

    In many big cities, a lot of old people keep birds, cats, dogs and other animals in their houses. These animals are friendly to the old people and never leave them. So the old people love them and see them as their good friends or families.

    It's not difficult to keep these lovely animals at home. But you have to take them to animal hospitals to give them needles (注射), so they won't get ill or they will make people ill. Now there are lots of animal food stores here and there. People can buy good animal food for their animals there. Old people can buy animal food on the phone or on the Internet. But it's a little more expensive.

    Sometimes it's kind of dirty and dangerous to keep animals. They sometimes look dirty and smell terrible and can be dangerous. For example, an old woman in Shanghai lost her life on the street for her pet dog.

    Maybe old people in big cities have many reasons to keep these nice and clever animals. They may feel lonely when their children leave. And these pets can be their great helpers. They are their good friends and help them in many things.

    After years of debate, gray wolves were reintroduced (重新引进) to Yellowstone National Park. Fourteen wolves were caught in Canada and moved to the park. By 2016, the Yellowstone wolf population had grown to more than 170.

    Gray wolves once were seen here and there in the Yellowstone area and other pans of United States, but they were gradually displaced by human development. By the 1920s, wolves had disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around. The disappearance of the wolves had many unexpected results. Deer and elk populations—major food sources(来源) for the wolf—grew rapidly. These animals ate large amounts of plants, which reduced plant diversity(多样性) in the park. With the disappearance of gray wolves, coyote (草原狼) populations also grew quickly. The coyotes killed a great number of red foxes in the park, and completely drove away the park's beavers (河狸).

    As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many framers were against the plan because they feared that wolves would kill their farm animals or pets.

    The government spent nearly 30 years thinking lip a plan to reintroduce the wolves. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

    As more and more schools rush to put digital devices（数码设备）in the hands of every student, many parents are becoming increasingly concerned about the quality of their children's education. The promise of increased student academic（学业上的）achievement through the use of technology hasn't produced any significant results in the past 20 years.

    Researchers at the University of California Los Angeles conducted a study in 2014 to determine if the social skills of elementary students were blocked by screen time. Two groups of sixth grade students were compared. One group was sent to an outdoor camp for one week with no screen time, while the control group live life as normal. After one week, the students at camp had made significant improvements over their peers（同龄人）. The good news is that when we limit access to screen time and give children the opportunity to interact face to face, they quickly become better at reading the emotional state of others. The bad news is that we have a generation of children that struggle with this basic emotional intelligence skill.

    Too much screen time has been linked to childhood obesity, sleep disorders, behavior problems, and academic challenges. But is there a difference between schoolwork and entertainment media?

    When students are using technology for academic work they are more likely to be communicating with peers, working cooperatively, and developing other important skills. However, all these are impossible when students watch entertainment media. They just sit and watch!

    Parents have right to be concerned about their children's screen time at school, but they should begin by discussing the use of digital media at home. Some parents are continuously engaged in their own devices, responding to every ring of their phones, receiving and sending messages. How can they expect their children to do better?

    Inner Mongolia Autonomous Region is an important ecological screen for the north of China and even the whole country. Building a green great wall to ensure China's ecological security is one of the most important things of autonomous region.

The largest ecological function zone in the north of China, Inner Mongolia has a variety of landscapes, including forests, grasslands, wetlands, rivers and lakes. In recent years, the region's environment has improved, with its forest and grassland area having increased and desert reduced.

    However, it still faces a number of challenges in ecological preservation. For instance, the region faces severe water shortages with the number of lakes dropping from 427 in 1987 to 145 in 2010. In addition to a lack of rainfall, huge water consumption in agricultural and industrial production has worsened the water shortage. Too much use of fertilizers has damaged the soil and affected the growth of grass, accelerating the expansion of the desert, which results from a lack of water.

The local government encourages planting trees on grassland as they can get more pay for trees than by growing grass. However, the trees they plant often have a low survival rate as they have a high water consumption rate. Also, to treat wetlands, some areas have planted a large number of a single tree species. This practice may damage biodiversity (生物多样性) and endanger the survival of certain animals.

Experts suggest taking the region's water resources and weather conditions into consideration in future ecological projects.

                                                  Printable Tags Turn Everyday Objects into Smart Devices

    Engineers have developed printable metal tags (标签)that could be attached to everyday objects and turn them into smart Internet of Things devices.

    The metal tags are made from copper foil (铜箔) printed onto thin, flexible, paper-like materials to reflect WiFi signals. The tags work essentially like "mirrors" that reflect radio signals from a WiFi router(路由器). When a user's finger touches these "mirrors", it disturbs the reflected WiFi signals in such a way that can be remotely sensed by a WiFi receiver like a smartphone.

    The tags can be nailed onto objects that people touch every day, like water bottles, walls or doors. These objects then become smart and connected devices that can signal a WiFi device whenever a user interacts with them. The tags can also be shaped into thin keypads or smart home control panels that can be used to remotely operate WiFi-connected speakers and other Internet of Things devices.

    Xinyu Zhang, a professor of electrical and computer engineering, named the technology LiveTag. He pictures people using LiveTag technology to track human interaction with everyday objects. For example, LiveTag could potentially be used to assess the recovery of patients who have suffered from stroke (中风). "When patients return home, they could use this technology to provide data based on how they interact with everyday objects at home, whether they are opening or closing doors in a normal way, or if they are able to pick up bottles of water, for example. The amount, intensity and frequency of their activities could be recorded and sent to their doctors to evaluate their recovery," said Zhang. "And this can all be done in the comfort of their own homes rather than having to keep going back to the clinic for frequent testing," he added.

    The researchers note several limitations of the technology. LiveTag currently cannot work with a WiFi receiver further than one meter away, so researchers are working on improving the tag sensitivity and detection range. Ultimately, the team aims to develop a way to make the tags using normal paper and ink printing, which would make them cheaper to mass produce.
