    We're sitting too much and it's dangerous. Most Americans spend more than seven hours sitting every day, and the more you sit, the weaker your body will be. Fortunately, there are simple changes you can make during the day—anywhere, even at the workplace—to improve your health.

    Park a few blocks away from the office each morning and walk to work.

    This allows you to start off your mornings actively and be ready to take on the work. If you take the bus, get off one stop earlier to take some light exercise before 8 a.m.

    Get up and move around the office once every 60~90 minutes.

    When you're busy with work, it's easy to forget the time. Set the alarm to remind you to get up and take a walk around the office. You can use this time to fill up your water bottle or go to the bathroom.

    Ask questions and discuss questions face to face.

    Go to your co-workers' office to discuss questions face to face, rather than send an email every time you have a question. This gives you a good excuse to move.

    Use your lunch break to move around outside.

    So many Americans today work during their lunch break. When possible, take advantage of this time to walk outside and enjoy the nice weather. Fresh air can make you keep a clear mind.

    A new rubbish sorting system (垃圾分类系统) has been put into use in Fangchengyuan Community in Beijing. Local people not only sort their rubbish, but also put QR codes (二维码) on it.

    "When the rubbish is collected and the codes are seen, I will get reward points to exchange for small gifts and even some money," one of the local people told reporters. "It's really creative and encouraging."

    This smart system has been carried out in 350 communities in Beijing. The capital of China has joined a list of cities in the country that take action to support rubbish sorting. For example, Shenzhen and Shanghai have made laws to punish people and organizations for not sorting rubbish correctly.

    China produces quite a lot of rubbish every year. Much of the rubbish is buried (填埋) in soil or burned without being sorted. Landfills (填埋场) take up a lot of land and have a risk of polluting the soil and water nearby. And burning rubbish can produce harmful gases. Through rubbish sorting, we can reduce the use of landfills and air pollution.

    What's more, rubbish sorting saves resources, which could bring economic benefits (经济利益). For example, a ton of waste paper can be reused to make about 850 kg of paper, saving 17 trees and 50 percent of water. Because of the benefits, some countries have developed successful sorting systems.

    Japan has a strict and detailed system. When people throw away a water bottle, the cap, the wrapper (包装纸) and the bottle itself have to go into three different bins. Every year, families receive special rubbish sorting timetables and directions from their local governments. They are advised to follow the timetables and directions when they throw away rubbish.

    In Australia, every family is provided with three rubbish bins—the red lid (盖子) bin for "general waste" like food and plastic bags, the yellow lid bin for "recycling" like steel and glass, and the green lid bin for "green waste" such as grass and leaves. On the streets, the bins are printed with pictures of the things that are allowed inside. It makes recycling quite easy.

    What makes you who you are as a person? You probably have some ideas of your own personality. Are you similar to Martin Luther King or Albert Einstein? Read about these types and find out.

    Canada is the second-largest country in the world, with almost 10 million square kilometres of landmass. Due to (由于) its size, it is divided into four different regions(地区).

    The Atlantic Provinces

    Fishing is the old industry in this region. Agricultural crops, such as fruit and potatoes, and forests, which produce paper and lumber(木材), form part of the industry. Traditionally depending on fishing and farming, they are developing other natural resources, such as oil and copper.

    Central Canada

    Ontario and Quebec form the industrial and manufacturing (制造业的) heart of Canada. They produce three quarters of Canada's goods. More than half of Canada's population lives in the cities in the southern part of Ontario and Quebec. Most of the people living in Quebec speak French.

    The West Coast

    The British Columbia Coast is Canada's western continental coastline (海 岸 线 ). Europeans settled (定 居 ) in British Columbia in the early 1800s. The railroad built by the government in the late 1800s made moving much easier. Thousands of Chinese came to British Columbia during this period to work on the railroad. British Columbia has the most valuable forest industry in Canada.

Salmon (鲑鱼) fishing is not only a popular sport, but also an important part of the industry. Pacific salmon are exported (出口) all over the world.

    The North

    The Yukon and the Northwest Territories (领土) cover a third of Canada. This huge region has a very small population. Most of the people are natives. There are several native languages, which are equal (平等的) in status (地位) to English and French. During the Gold Rush at the end of the 1800s, thousands of miners (矿工) came to make their fortune (财富). Mining is still an important industry in this region.
