However, there is some difference in lifestyle between city settlers and the country people. Almost 90 percent ofthe population lives in the fast-paced cities along the coast and has little more than a passing familiarity with the desert. The major cities preserve images of colonial heritage, but on the whole the impression is modern, with new buildings reflecting the country's youth. In contrast, therural communities tend to be slow-moving and conservative. For many years, Australia was said to have "ridden on the sheep's back" , are ference to wool being the country's main money earner. However, it is nolonger dominant ( 主宰的). Much of Australia's relatively sound economy is now achieved from natural coal and wheat, and by being the largest diamond producer in the world. Newer industries such as tourism and wine making are also increasingly important. Australians are generally friendly and relaxed, with a modest sense of humor.

    Yet, contrary to wide spread belief, very few Australians have true prisoner origins. Within only one generation of the arrival of the First Fleet in 1788, Australia had become a nation of immigrants. Originally coming almost entirely from the British Isles, today one in three Australians comes from elsewhere. Australia's liberal postwar immigration policies led to a flowing of survivors from war-torn Europe. The emphasis has changed in recent years and today the majority of new immigrants are from Southeast Asia. Today Australia is a "mixture of nations" and although some racism exists, it has generally been a successful experiment and the country is reasonably proud to have one of the most harmonious multicultural communities in the world.

    Doing homework not only can help children master the knowledge they have learned, but also can train their abilities of finishing the work alone, planning the time and doing the duties. But some children don't like to complete the work. Why? There are some reasons.

    Some children feel it is very difficult to do their homework, because they can't understand their teacher clearly, and can't follow their teacher's teaching process. Maybe there is something wrong with their intelligence.

    But some children's intelligence is normal. They are even cleverer, but they don't listen to the teacher carefully. It is hard for them to sit well and pay attention to anything. It needs to carry on the attention centralized（集中注意力）training to help the children.

    Some children love their teacher and then they like the subject. Their interest depends on the teacher who teaches them. So every teacher should be helpful and kind. It can make children love you and the subject you teach. So they can do their homework happily.

    Anger itself is neither good nor bad. It's what we do when we're angry that matters. Anger is a tool that helps us to read and respond to the social situations that bother us. But how can we keep it under control?

    It's normal to think that getting angry is bad and many times we punish ourselves for doing so. But contrary to popular belief, research indicates that anger increases optimism, creativity and efficiency. In addition, studies suggest that anger can lead to more successful negotiations at work, as well as in our personal lives.

    In fact, suppressing（抑制）anger can be very bad for your health. In this sense, Dr. Ernest Harburg performed a study by monitoring a group of adults and their capacity（最大容量）for anger. What he found is that the men and women who suppressed their anger as a response to an unfair attack had a higher risk of developing bronchitis or suffering from heart attacks , and were more likely to die before their colleagues who let their anger surface when they felt bothered.

    When anger arises, we feel the need to either prevent or put an end to this powerful feeling for the benefit of our welfare or the welfare of those we care about. But this act of kindness, mercy, love or justice isn't beneficial in this way. However, it's certainly a good thing to be cautious when anger begins to surface. Expressing your anger can be appropriate with certain people at certain times. The question lies in how to do it without losing control. The key to expressing your anger is finding the appropriate tone for expressing what it is that upsets you. But to avoid unnecessary shouting, hitting, or other violent reactions, it's worth taking a moment to step back and think, even though we may be in the middle of an argument with someone.

    On October 17, 2016 the Shenzhou-11 manned spaceship was sent into space from the Jiuquan Satellite Launch Centre in Gansu. Two days later the spaceship successfully connected with the space laboratory Tiangong-2. It meant China got closer to its plan of building a space station in 2020.

    The spaceship took two Chinese astronauts to space this time. Jing Haipeng was an experienced astronaut who flew on Shenzhou-7 in 2008 and Shenzhou-9 in 2012. But it was Chen Dong's first space flight.

    Jing and Chen were given a 30-day task on Tiangong-2. They tested new technology and did experiments to prepare for future space station tasks. The astronauts themselves were also the subject (对象) of those experiments. The life support devices (设备) they used and how they lived inside the space laboratory were studied. No Chinese astronaut had stayed in space for that long before.

A month-long space task was not easy, so Chinese scientists and engineers had come up with lots of new technologies to allow astronauts to stay more safely and more comfortably in space. One of the new technologies tested during this task was a device called "space hospital". The space hospital was two little silver boxes tied around the two astronauts, legs. Through the "space hospital", scientists and doctors on the Earth could watch the astronauts, heart rate and temperature. When the astronauts felt tired, the "space hospital" could even massage (为…按摩) them.

    After this task, China was expected to send an unmanned cargo spaceship (无人货运飞船) in mid-April the next year. It docked with Tiangong-2 and took new fuel to the space laboratory.

    Health insurance can be very expensive. Some working people do not make enough money to pay for it. In the US there is a program called Healthy Families. This program offers people health insurance at a low cost.

    Families are charged about $7.00 a month for every child, and $10.00 for every adult. It costs much less than any other kind of health insurance. Having health insurance is very important. With this insurance, people can see a doctor when they are sick or hurt.

    The program is not expensive at all, but many people are still not enrolling (登记) in it. People say that it still costs too much money. They need all of their money to pay for things like food and rent.

    It would be great if everyone could have health insurance. People are working hard to come up with ways to make this happen. One idea is to make the Healthy Families Program free for some people.

    It is important for people to see a doctor when they need to. The Healthy Families Program makes it possible for more people to do this. Many ideas are being considered. Hopefully some of them will allow even more families to get health insurance.

    The Healthy Families Program is made to help those who don't have welfare (社会保障金) and cannot earn enough to pay for private health insurance. It is an important program, but officials say that too many people are signing up for it and then dropping out (退出) because of the Healthy Families Program's cost.
