Population Change

    Why is the world's population growing？The answer is not what you might think. The reason for the explosion is not that people have been reproducing like rabbits, but that people have stopped dropping dead like flies. In 1900,people died at the average age of 30.By 2000 the average age was 65.But while increasing health was a typical feature of the 20^th century, declining birth rate could be a defining one of the 21^st.

     Statistics show that the average number of births per woman has fallen from 4.9 in the early 1960s to 2.5 nowadays. Furthermore, around 50% of the world's population live in regions where the figure is now below the replacement level(i.e.2.1 births per woman)and almost all developed nations are experiencing sub-replacement birth rate. You might think that developing nations would make up the loss(especially since80% of the world's people now live in such nations),but you'd be wrong, Declining birth rate is a major problem in many developing regions too, which might cause catastrophic global shortages of work force within a few decades.

     A great decline in young work force is likely to occur in China, for instance. What does it imply? First, China needs to undergo rapid economic development before a population decline hits the country. Second, if other factors such as technology remain constant, economic growth and material expectations will fall well below recent standards and this could invite trouble.

     Russia is another country with population problems that could break its economic promise. Since 1992 the number of people dying has been bigger than that of those being born by a massive 50%,Indeed official figures suggest the country has shrunk by 5% since 1993 and people in Russia live a shorter life now than those in 1961.Why is this occurring? Nobody is quite sure, but poor diet an above all long-time alcoholism have much to do with it. If current trends don't bend. Russia's population will be about the size of Yemen's by the year 2050.

     In the north of India, the population is booming due to high birth rates, but in the south, where most economic development is taking place, birth rate is falling rapidly. In a further twist, birth rate is highest in poorly educated rural areas and lowest in highly educated urban areas. In total,25% of India's working-age population has no education. In 2030,a sixth of the country's potential work force could be totally uneducated.

    One solution is obviously to import foreign workers via immigration. As for the USA, it is almost unique among developed nations in having a population that is expected to grow by 20% from 2010-2030,Moreover,the USA has a track record of successfully accepting immigrants. As a result it's likely to see a rise in the size of its working-age population and to witness strong economic growth over the longer term.

    Green is not always referring to the color. In some cases, it is the term used for being environmentally friendly. If you've been looking to replace your furniture, consider going green because environmentally friendly furniture offers many benefits. Here are a few tips to get you started on your hunt for the perfect eco-friendly furniture.

    First, environmentally friendly furniture isn't harmful to your health. Also its manufacturing process doesn't cause damage to the environment in any way. Besides, by purchasing eco-friendly products, you prevent deforestation and global warming to some extent in your own way. You do your part in protecting the environment. Environmentally friendly furniture is cost-effective as well.

    The materials that are used in furniture are what make them green. Materials can be good for the environment either because they are materials that are considered renewable resources or they are all natural. A lack of chemicals and toxins (毒素) in green furniture also means it is a better choice for the environment. It may be hard to imagine that a sofa or a table could actually be a green product but they really can be depending on what they're made of.

There are a lot of renewable sources that manufacturers could use when building the furniture, so you should be keeping an eye out for them. Bamboo can be an excellent replacement for wood and can also replace plastics and metals in some furnishing. Cotton is a sofa fabric that is safe for the environment and it can be replenished (补充) often. Hemp is also a renewable source that can be used for fabric and twine.

    Recycled materials also can be made into green furniture. Metals can be recovered and remade into new things such as frames and foundations for sofas. Recycled plastic can also be made into furniture such as tables and chairs. Touching up old furniture instead of buying new items is very cheap way to be green. Yard sales and second-hand stores sell furniture too and buying the used means new things won't be made, so no more damage has to happen to the earth.

    Therefore, when you want to hunt for the perfect environmentally friendly furniture, you should try to know the type of materials which are used in building the furniture.

    Every person wants to achieve the goals set at the beginning of a new school year. The following are some ways to help you achieve your goals.

    {#blank#}1{#/blank#}When it comes to choosing your goal, ensure that it states precisely what it is that you want to achieve. Don't generalize. Your goal should involve both what you want to achieve and the effort that you will put in to achieve it. 

    {#blank#}2{#/blank#}Having a copy of your goal makes it real. You can write you goal in a journal you'll be keeping all year, or you can write it on a poster and stick it on your desk so that you can look at it each day. Every time you remind yourself of your goal, you're training your brain to accept the effort needed to make the goal happen.

    Try various methods. One may not work while another may be just right for you. {#blank#}3{#/blank#}Some people learn best through writing, some through listening and reading, and some through talking it through. Once you realize which way works for you, you can work better and achieve your goal easily.

Stop telling yourself you can't and start telling yourself you can, and talk about you are doing rather than hoping you can do something. Always believe that you're capable, even if you have difficulty along the way.

    Reward yourself along the way. {#blank#}5{#/blank#}Occasionally, when you've achieved certain “milestones” in your goal plan, take a break and reward yourself. Watch a movie, visit a friend who lives across town, go to the ice cream shop with your friends or buy yourself something new.

    {#blank#}4{#/blank#} So although a female panda ant lays approximately 2, 000 eggs a year, a considerable amount of eggs to support their survival, this species is still on the edge of dying out.

    This species was first discovered in the coastal region of Central Chile in 1938. {#blank#}5{#/blank#}

    At the age of forty­five, my usually well­ordered life became full of changes. After twenty­two years of working in a bank, a plan to use less staff led to the unemployment of over one hundred people. Unluckily, I was one of them.

    My once secure future became uncertain. However, I was not a single parent, so the family did not depend only on my income and my husband can support the family. My motto has always been, "Change is good; change is progress", but when it affected my livelihood, I had to change it. "Accept change and make the most of it." From the beginning, I chose to look at this matter not as bad luck, but as a welcome chance. I refused to become sorry; instead, I actively planned to do something new and different.

    Having a positive attitude made all the difference in the way I pursued the future. First, I decided to return to college and graduate many years later than I should have. Doing this at my age took more than a little courage. Not being a graduate had never held me back in my career in the bank, but now it's a personal goal I longed to achieve. With a lot of determination, I went to evening classes and became an adult student. In the class, I became more and more confident. During this time, I realized that no matter what life throws in our way, nothing can hinder our personal growth.

    The second thing I did to improve my inner self was to reevaluate my past life. It used to be filled with endless, and sometimes meaningless events. But now, my heart and life are completely around people I care for.

    The loss of my job led to some positive changes in my life. Revisiting the past made room for the future. I realize that I have accepted the change, and am making the most of it.

Ready for final year

    Even though they're anxiously awaiting their gaokao, Senior 3 students feel relieved after having survived their busiest year of high school.

    Your milestone year begins in just two months, so how can you make the most of it? Here, three graduates offer some practical advice to help you navigate (航行) your final year in the right way.

    Sun Hairuo, High School Affiliated to Renmin University of China, Beijing:

    Think ahead about your major. Even though some universities allow students to switch to a new major after enrollment, it still involves a lot of effort to do. So while you're preparing for the gaokao, start to consider what field you want to major in at the same time.

    When I was aware of my interest in social science, I began to collect information on the internet about what courses I'd like to take in university and what life would be like on campus if I chose this direction. Don't judge a major before you know everything about it, since your entire future depends on it.

    Qian Wenjing, Hangzhou Foreign Language School, Zhejiang:

    Enjoy a hobby alongside your studies. It's important to get high marks in all subjects, but if you have nothing that can distract you from the piles of homework, you'll have no motivation.

    For example, I run a WeChat public account, which you can find by searching for “大嘴小个儿” on WeChat. On it, I share my reflections on life, recommend good books and introduce learning methods to others. I also make videos on how to write an interesting daily journal for the video platform bilibili.com.

    So, keep on top of your schoolwork, but make sure you find time to let your hair down sometimes too.

    Wang Zixin, Beijing No 4 High School, Beijing:

    Create your own system of knowledge using a notebook. In the review stage, find your weak points on every science subject after each exam. Summarize the knowledge behind the errors in your notebook — this will not only identify the problem, but will also save you time when you don't have to spend so long figuring out the answer.

    As for liberal arts subjects such as Chinese and English, write down any memorable sentences you come across in your notebook.

    And keep it in mind that improvements don't happen right away — it takes time to get better.

    Ready for final year
