尊敬的老师们，亲爱的同学们：
大家好!
世界上有一种快乐叫探索，世界上有一种质疑叫勇敢，世界上有一种奇迹叫科学!“科学”，一个多么让人感到奇思妙想的名字。它，让人不停追索、求真，不断地在每一次探索中进步，总会让人们感到不可思议而赞叹不绝!
科学需要不断探索，坚持不懈，才能呈现一些非凡的发现。如我国伟大的地质学家李四光在不断学习、探索，以坚持不懈的精神在中国发现“冰川”痕迹，并以科学的地质知识证明“冰川”的所在，这一个伟大的奇迹惊动全世界，他以丰富的地质知识和顽强的科学态度让一个奇迹发生了!
在每个人的脑海中都存在一个细小又令人惊奇的小东西，那就是——科学细胞。也许有人会说：“我不爱科学。”在这里我可以坚定地对你说：“你不懂科学。”科学是一种有趣的东西。他可以令人不断发现，其实你说不爱科学是假的，因为在我们的生活中科学无处不在。如：我们的吊机为什么会轻易地吊起重物?那是因为杠杆的原理。铁为什么会生锈?那是因为空气与铁结合的结果。为什么能那么准确地说出原因呢?因为有它——科学。
我为我能爱上科学，探索科学而感到自豪!我要坚定地说一句：“世界上因为有了科学的存在而变得更加绚丽多彩!”

distinguished parents: good afternoon ladies and gentlemen thank you for your time to attend today's symposium today to attend the parents of the child belong to different degrees of obesity children's parents. hope that through today's lecture help parents and children. as people living standard unceasing enhancement parenting and children's dietary structure changes nutrient rich combined with the only child's special status and unscientific feeding incidence of childhood obesity is gradually increasing. we are beginning to realize that: childhood obesity is not a lovely sign obese children in the study character and life and so on various aspects will have a lot of inconvenience. thick samuel therefore we should not rain completes the relevant publicity and education work take the necessary preventive measures in order to effectively control the occurrence ji. kindergarten is important place the growth of preschool children's life so make good feipaner project management and the prevention and control work is our kindergarten care teachers bounden duty.
in order to reduce and prevent children get fat we together with parents to discuss several problems: such as: what is the simple obesity? simple obesity causes? standards of obesity? obesity can bring what harm? how to treat and so on. 1 what is the simple obesity? obesity is due to the heat energy metabolic disorders the consumption of calories more than heat cause the body fat accumulation.
childhood obesity has two season:
(1) infancy (that is within one year of age). in infancy the activities of the child is small have a long sleep eat nutritious food and some parents give their children eat don't control children eat a cry to him so it is easy to cause obesity. in infancy is fat children in two or three years later with the increase of children range range expansion obesity can be improved. but there are also children continue to get fat has maintained into adulthood.
(2) the early school age (i.e. 5-8 years). moderate above simple obesity of children age began to get fat is mostly in the 5 s the obesity of children this period is mainly caused by bad way of life: on the one hand the traditional diet habits in affects children if eat and drink too much eating and drinking; on the other hand the western dietary patterns are interfered with domestic children's diets such as too much sweet food and western fast food drink soft drinks cause excessive intake of calories and exercise less over a long period of time. as a result the extra calories to fat obesity. in obese children in china we found that obese children love to eat all kinds of meat sweet love to drink good appetite eat fast don't want to eat vegetables. cause the cause of obesity in addition to the thermal energy intake too much too little exercise meditation time too long wait for a reason genetic endocrine disorders can also cause obesity.
2 simple obesity causes?
(1) genetic factors. according to the relevant information the parents have the obesity the possibility of children obesity has 32 ~ 34%; both parents are obese the incidence of child obesity increased to 50 ~ 60%. on the other hand 72% of fat children parents have at least one person also have obesity. and now have found a variety of genes associated with obesity.
diction is eating too much and overnutrition. obese children tend to eat a lot of high fat food sweet food especially the unlimited access to eat snacks and drink sweet drinks and these can cause obesity.
(3) movement. parents were busy with work no time to accompany children play together always let the children stay at home such as tv children can not get enough exercise gradually becomes less physical static activities more and more such as watching tv playing video games and so on these can make children reduce activity fat growth. fat kid inactivity inactive children become more fat the result is a vicious circle.
(4) parents have the wrong idea. especially the parents of obese children think children as long as can eat is a good thing so the easiest way to produce a obese children.
(5) the poor eating habits. investigation shows that the more the more obese likes to eat meat don't like to eat vegetables such as child piddle parents aren't paying attention. in addition children inadvertently desperately eat more snacks get into the habit of snacking so poor eating habits will appear fat. so for children's obesity should be in many ways to find the reason targeted for treatment.
