Most people say that most people have not more than 30 friends at any given time, and 400 over the whole of their lives. However, on social networking sites, most users have about 150 friends. If these numbers are correct, then friendship means different things in different situations.

    Also, there are no rules about friendship. There are no instructions about how to make friends, how to keep friendships going, and how to finish friendships if we want to move on. People have very different opinions about this: some people would die for their friends and they value them more than family. Others say that friends are temporary, only there to help each other until they are no longer needed. If people with such different views become friends, this can lead to problems.

    Because of these different definitions of friendship, it is easy to be unhappy about our friendships. We may want them to be deeper or closer, or we may want to have more friends in our lives. Sometimes we simply do not have the time to develop our friendships, or we fear we have left it too late in life to start. If we move to another country or city, we have to find ways, to make new friends again.

    This dissatisfaction shows us how important friendships are for most of us. We should not think that it could be too late to build friendships. We also need to understand that the need to be around other people is one that is shared by many. Therefore, we should not be too frightened about starting to talk to people who in the future may become our friends: it is likely that they too would like to get closer to us. Remember what people say: strangers are friends we have not met yet.

    When other nine-year-old kids were playing games, she was working at a petrol station. When other teens were studying or going out, she fought to find a place to sleep on the street. But she beat these terrible setbacks（挫折） to win a highly competitive scholarship and gain entry （录入）into Harvard University. And her amazing story has inspired a movie, “Homeless to Harvard: The Liz Murray Story”.

    Liz Murray, a 22-year-old American girl, has been writing a real-life story of willpower and determination. Liz grew up with two drug-addicted parents. There was never enough food or warm clothes in the house. Liz was the only member of the family who had a job. Her mother had AIDS and died when Liz was just l5 years old. The effect of that loss became a turning point in her life. Connecting the environment in which she had grown up with how her mother had died. She decided to do something about it.

    Liz went back to school. She threw herself into her studies, never telling her teachers that she was homeless. At night, she lived on the streets. “What drove me to live on had something to do with understanding, and by understanding that there was a whole other way of being. I had only experienced a small part of the society,” she wrote in her book Breaking Night.

    She admitted that she used envy （妒忌）to drive herself on. She used the benefits that come easily to others, such as a safe living environment, to encourage herself that “next to nothing could hold me down”. She finished high school in just two years and won a full scholarship to study at Harvard University. But Liz decided to leave her top university a couple of months earlier this year in order to take care of her father, who has also developed AIDS. “I love my parents so much. They are drug addicts. But I never forget that they love me all the time. ”

    Liz wants moviegoers（常看电影的人） to come away with the idea that changing your life is “as simple as making a decision”.

    Here's advice on where to find job applications.

Company Websites

    If you are interested in working for a particular company, visit their website. Career information is usually listed in the “Careers” or the “About Us”section of the site. Often, you will be able to apply for all company positions directly from the website.

Job Boards and Engines

    If you aren't sure what company you want to work for, you can look for job applications on job boards and job search engines. These contain job listings for positions at many different companies. Sometimes you have to go to the company website to fill out a job application. At other times, you can apply directly on the search engine or job board.

In Person

    Applying for a job in person is a little different than applying for employment online. It's not as complicated, but you will need to be prepared to apply and interview on the spot. You have to make sure you dress professionally, and bring all the materials you need.

    Below is a list of sample employment applications and click to find what you want.

    China will build a comprehensive (综合性的) network to detect (检测) pollution of the land, sea and air by 2020, employing satellites, drones(无人机)and remote sensors to monitor the environment.

    The national leadership agreed to the network plan in July, saying the government will lead the monitoring, share information among departments and regions, and be held accountable (追究责任) if violations (违规行为) are found, the Ministry of Environmental Protection said on Tuesday.

    Satellites, a major tool for monitoring air pollution, will receive a boost (大力发展)  this year. The ministry said it will accelerate research on two atmospheric environmental monitoring satellites.

    The ministry will improve a remote sensor network, guided by the goals of the 13th Five-Year Plan (2016-2020), which is scheduled to be released at the end of this year, according to the ministry's Environmental Supervision Department.

    Remote monitoring has played a bigger role in locating pollution sources. Drones helped authorities locate polluted areas in the Tengger Desert in northern China and identify scattered summer straw burnings.

    Hebei province, which has a serious air pollution problem, has cooperated with the ministry's Satellite Environment Center to conduct monitoring from satellites and monitoring stations since January last year.

    "We used the data from the center's satellites to forecast the movement of smog during the Asia-Pacific Economic Cooperation meetings in November, "Zhang Feng, an engineer in the Environmental Supervision Department of the provincial environmental watchdog, said on Tuesday.

    Data collected from monitoring stations helped authorities provide accurate forecasts on hazy days during that period, he said.

    Vaping can be just as damaging to your health as smoking. But the minute you kick the habit, you'll feel a difference.

    Vaping is the use of electronic cigarettes-e-cigarettes. Vaping became mainstream in the United States in the late 2000s. When e-cigarettes first hit the market, people believed they were a safer choice to tobacco cigarettes. We now know, however, that vaping, like smoking cigarettes can be quite damaging to your health-and equally addictive.

    Kids and teenagers are especially attracted to vaping, thanks to attractive flavors. Vape use in high school students rose by 900 percent between 2011 and 2015.

    Quitting vaping can be difficult, just like trying to stop smoking. There are some immediate, though often temporary, negative effects. The positive ones soon outpace the negative, however.

    In as little as 20 minutes, your heart rate returns to normal, your blood pressure drops, and your circulation starts to normalize. Your breathing may improve, too.

    Daily e-cigarette doubles a person's risk for a heart attack. If you quit, however, the risk begins to fall very quickly. Also, vaping, like cigarette smoking, can blunt your senses, reducing your ability to smell and taste. After just 48 hours without vaping, you may begin to notice your ability to taste and smell food has improved. Nicotine affects more than your brain: new research suggests nicotine can raise your blood sugar, too.

    Smokers often have a troublesome cough or make a breathless sound when they breathe that many refer to as a smokers cough. Smoking even e-cigarettes can badly harm your lung health and make fighting off infections difficult. Quitting, however, will help your lungs recover. After one month, your lung capacity improves.

    There will come a day when the bad habit of vaping won't have any lasting influence on your body and your health.
