5．Children know that summer is probably the most fun of all seasons．However，experts say it is also the most dangerous，especially，for children aged 14 and under．In its first study of children's safety in the US，the National Safe Kids Campaign （NSKC） found that nearly half of the injury-related （与受伤相关的） deaths among children happened in summer．
Experts are not surprised by the study's results．They always know summer is a dangerous season for children．During the summer，children are out of school and spend more time outdoors．They are more likely to get into an accident or be injured．"While we encourage children to be active and spend more time outdoors，they need to understand the importance of safety，"said Everett Koop，an expert of the NSKC．
To help children stay safe，the NSKC started a"Make it a Safe Kids Summer"campaign during National Safe Kids Week，from May 5 through May 12．Here are some important summer safety tips from the NSKC：
●Always wear your seat belt．
●Make sure there is an adult around when you decide to go swimming．

4．A large part of China experienced larger amounts of smog （雾霾） than usual this January and the air was badly polluted．The distance one could see was shorter than 1，000 meters in Beijing，Tianjin，and the provinces of Hebei，Henan，Shandong，Jiangsu and Anhui．In some areas，it was down to 200 meters．
     People usually set off firecrackers （爆竹） to celebrate Spring Festival．But because of the smog，this year seemed very quiet．It was really different．A man called Zhang Wei said that his friends and he hadn't set off a single firecracker．
"We all suffered from last month's smog．If we don't call an end to the firecrackers，the environment will get worse and worse during the holiday．"Said Zhang Wei．He called on more people to set off fewer firecrackers during this year's Spring Festival holiday by putting up a notice in his neighborhood．

     To clean the sky，more than ten provinces including Guangdong，Zhejiang and Jiangsu have started to use national 4 standard （标准），which is expected to reduce （减少） vehicle emission （车辆排放） by 30% to 50%．Beijing even has started to use the stricter national 5 standard．

3．Different vitamins are found in different foods．Then which foods should be eaten to keep us healthy？Let's look at some important vitamins for the answer．

Vitamin A helps to protect skin from becoming dry．It is also helpful to the eyes．Without vitamin A，you cannot see well in darkness．Vitamin A is found in animal liver and yellow part of eggs．Sweet potatoes，carrots and other dark colored fruit and vegetables have something that the body can change into vitamin A．

Vitamin B changes foods into energy and helps the heart and nervous system（神经系统） to work smoothly．Without it，we will be weak and will not grow．It is found in grains and other foods like beans，nuts，meat and fish．
Vitamin B helps to produce red blood cells．It is found in foods like eggs，meat，fish，milk and green leafy vegetables．

Vitamin C is needed for strong bones and teeth，and for healthy blood vessels（血管）．It also helps wounds to heal（意合） quickly．The body stores little vitamin C，so we must get it in foods like oranges，and cabbage．

Vitamin D increases the levels of calcium（钙） in the blood．Calcium is needed for verve and muscle（肌肉） cells to work normally，as well as to build strong bones．Fish liver oil has vitamin D．In some countries，milk producers add vitamin D to milk so that it will be good for children．

2．This spring，the H7N9 virus（病毒）hit China．This brings the total number of H7N9 cases to 124 in China．So far，23 people have died．
Most of the patients seemed to have the common flu．Other patients had a fever and cough．They also had trouble breathing．
According to the research，people believe the H7N9 virus was from the farm birds sold at markets and birds flying through China．How can you stay away from it？It's important to wash your hands a lot every day．You must drink boiled water，cook meat and eggs form birds completely．If you are working with farm birds，keep birds away from areas where you eat or sleep．If someone is ill and has a fever and pain in his throat，you must take him to hospital as soon as possible．Luckily，it seems that the H7N9 virus doesn't spread from man to man．Scientists said：Most people caught it because they had ever been with animals like chickens and ducks．

1．When an animal becomes extinct（灭绝），we will never see it again，except for some bones（骨头） in the ground．How sad!People are cutting down large forests in Europe，Asia and other parts of the world．This destroys homes of many wild animals．For example，some monkeys and apes（猿）eat the fruit and leaves in the tall trees．People cut down all the tall trees，leaving only the short ones．If the monkeys and apes don't have food，they will die．With more and more people on Earth，there is less room for other animals like bears and wolves．
Some animals are dying off because people hunt（猎杀）them for food．Some people shoot tigers，lions and other animals for fur to make money．They kill elephants for their teeth，and also force some of them to drag（拉）heavy machines to help them cut down trees．Tourists can hurt animals，too．Turtles lay their eggs on beaches in countries such as Greece，but they can't do this when tourists are on the beach．
Pollution（污染）is another killer．Some factories pour dirty water into rivers，and then many fish get sick and die．And one day，the Arctic （北极） night melt because of global warming（温室效应）．Then where will polar bears live？

19．Heat and cold can make pain go away．Heat makes our blood move faster and cold helps our nerves（神经）relax．
If you are in pain because you exercised a lot，your muscles（肌肉）need a lot of blood．Blood helps carry the pain away from your muscles．The more blood that comes and goes，the more pain is taken away．That's why sportsmen like to take a hot shower or sauna after exercising．Also，if a sportsman hurts a muscle，the team trainer will put something hot on the sore muscle．
Cold works if you hit your knee or hurt your ankle（脚踝）．At this time，the injured area may get bigger．This is called inflammation．Cold helps to make inflammation smaller．Cold also makes your nerves relax．Nerves in your body tell your brain about pain．
It's always a good idea to ask a doctor about using heat or cold．Never use too much heat or cold!Put a towel around a hot water bottle or ice before putting it against your skin．If you don't，the heat or cold may hurt your skin．
