The Chinese Yellow Sea Wetlands are among them. They are in Yancheng, Jiangsu Province. They are home
for many different kinds of birds and animals. The world"s largest Milu Deer Nature Reserve (自然保护区) is
in them. More than 700 Milu deer live freely there. There are not many red-Crowned cranes in the world, but
every winter you can see some in the red-Crowned Nature Reserve in the Yellow Sea Wetlands.
The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine,
too. They are really good places for wildlife (野生动物). Offering food and home for some special kinds of
animals and birds is not the only reason why we need to protect wetlands. Wetlands are important because
they also prevent flood. But some people want to change the wetlands to make more space for farms and
buildings. This means there will be less and less space for wildlife.
Luckily, more and more people are beginning to realize the importance of wetlands and wildlife. Every year,
on February 2nd, many activities are held to tell people more about wetlands.
( )1. The Chinese Yellow Sea Wetlands are in the west of China.
( )2. Usually the weather in the wetlands is pleasant.
( )3. February 2nd is the world"s wetlands Day.
( )4. We must protect wetlands only because they can offer food to the animals and birds.
( )5. Wetlands are valuable resources of land on the earth.

Spending two or three hours playing outdoors each day can reduce a child"s chance of becoming short-sighted, a research shows. _____ The Australian government researchers believe that the sunlight is good for people"s eyes. They compared the vision (视力) and habits of 100 seven-year-old children in Singapore and Australia. In all, 30% of the Singaporean children were short-sighted - this rate (比率) was ten times higher than Australian children. _____ However, the Australia children spent an average (平均) of two hours a day outdoors — 90 minutes more than the Singaporean children.

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." | |||
