Recently our class has conducted a survey about"The growth of post-90's generation".People have different opinions on it.Some people think that the post-90's generation are confident,ambitious and independent in thinking.They are fond of new things,ready to accept and try them.What's more,they have many new ideas,which makes them more creative.It's especially worth mentioning that they are enthusiastic and caring.They treasure friendship and are good at communicating with others.
However,others argue that the post-90's generation are too self-centered and dependent on their parents in life or teachers in study.They tend to live a comfortable life but are less able to overcome frustration.Besides,some of them lack the sense of responsibility and don't know how to show gratitude to others.Worse still,many are so weak in controlling themselves that they are often addicted to the Internet.

20.Lead poisoning (铅中毒)occurs when lead is present in high levels in the blood of a person.It is one of the most common medical problems found in children.And it's important to recognize the presence of lead in children's bodies because lead is very harmful.
Children have the tendency to go around and put things in their mouths like paint peelings.This is one of the main causes of lead poisoning.It has also been found that children born in poor families have higher chances of getting exposed to lead.
Some of the common symptoms of lead poisoning in children are headaches,stomach pains,hair loss,muscle weakness,and weight loss,etc.
Lead poisoning can have severe effects and can lead to heart diseases,kidney diseases and neurological(神经系统的)problems.It can also result in mental dullness and a low I.Q.level.There have been cases where lead poisoning proved to be terminal for children.
It's difficult to easily recognize whether a child is affected by lead poisoning,as the symptoms of this disease can occur due to some other medical problems.Therefore,children under the age of 6should regularly be checked to know the level of lead in their blood through blood tests.It's possible to completely cure a child with lead poisoning through treatment.Usually the oral medicine chelator(螯合剂)is given to the children.Sometimes,children are given an injection(注射)for reducing the lead level.Children who have very high level of lead in their blood would need treatment for a long period of time and would also be put on a special diet.
Parents have to take certain precautions to lower the chance of lead poisoning in children.Cleaning the house regularly and removing shoes at the door after coming in form outside will prevent the lead particles from entering the house.Children should be put on a healthy diet,containing high proportions(比例)of calcium and iron,such as eggs,milk,fruits,potatoes,etc.
Which helps to keep the lead levels in control,in the children's bodies.
In short,it's a must to be cautious and careful,and protect your children from the horrible consequences of lead poisoning.
