Some western countries insist that China is one of the world's biggest greenhouse gas emitters
(温室气体排放者). But in fact our government has taken actions a    1      to struggle with climate change.
       Firstly, the public are educated to p    2     more attention to the environment. As the government expects,
the people have reached a very h    3     level of knowing low-carbon economy (低碳经济). I    4      you
watch TV, listen to the radio or read newspapers, you'll find low-carbon lifestyle has become a fashion.
Secondly, developing renewable energy is another action. The government is b    5     many wind farms and
solar power stations in the deserts. Of course, w    6      a long time, China will continue using the coal. At the
same time, the government has been making l    7     to punish those people who dare to destroy the
environment. Besides, some s    8     have suggested that greening the deserts is more important than developing
new forms of energy. Their l    9     research shows that 80% of the CO2 in the atmosphere comes from
landuse.
      As we know, China hasn't a    10     a balance between the green lifestyle and the economic growth, but we
are on the way. We'll take more actions to reduce the greenhouse gas emission.

      Have you ever stayed in a hotel? Most Chinese hotels often provide guests with things like disposable
(一次性的) toothbrushes, toothpaste, shampoo and slippers. Many guests like the idea because they don't have
to bring their own. But, if you travel to Beijing, remember to bring your own things. Starting from June, some
hotels in Beijing will no longer provide guests with these disposables. They want to ask people to use less
disposable things.
      Many disposable things are made of plastic. People throw them away after only using them once. It is a
waste of natural resources and is very bad for the environment. Do you know, one Chinese person makes as
much as 400kg of waste a year! Most of that waste comes from disposable things. In Beijing, people throw
away about 19,000 tons of plastic bags and 1,320 tons of plastic lunch bowls every year! Plastic can take
between 100 and 400 years to break down. So the less plastic we throw out, the better. So, wherever you travel,
bring your own things and use them again and again.
      Back at home and school, you can also do something to make our world a better place. Try to do these
things in your daily life: Use cloth shopping bags, not plastic ones. After using a plastic bag, wash it out and let
it dry. Then you can use it over and over again. Do not use paper cups. At your school canteen (食堂), use your
own bowl and chopsticks instead of disposable ones.

    Vitamin (维生素) D is called "sunshine vitamin," and it is very important to health, yet more Americans
are not getting enough, U.S. researchers said on Monday. Researchers found that 75 percent of Americans
can't reach the levels of vitamin D, up from about 50 percent of them 20 years ago. Getting enough vitamin
D can be easy: spend 10 minutes in the sun with legs and arms exposed (暴露), or take vitamin pills.
    "But people's habits have changed…they are less active and outdoors less, and also protecting their skin
from the sun because of skin cancer risk (皮癌风险)," said Dr. Adit Ginde, who did the study. Traditionally,
vitamin D has been seen important to bone (骨) health and to prevent rickets (软骨病), but recent discoveries
show many kinds of cells (细胞) use vitamin D in some way, Ginde said.
    Food can boost (提升) vitamin D levels, but only a few foods. Those include some kinds of fish (salmon,
sardines, tuna and mackerel) and milk. But the amounts in milk are not enough to keep people healthy. In the
last few years, vitamin D has gained more attention. People are paying a lot more attention to it. A second
study in the journal supposed the idea of providing more vitamin D for bone health.
    Researchers did a research on some people aged 65 or older. They found that spinal bone fractures
(脊椎断裂) decreased (卜降) 20 percent when the patients took vitamin D every day. Researcher Heike
Bischoff-Ferrari wrote in the report. "it is possible for people to increase the amount of vitamin D earlier to
keep healthy."
