½â´ð Dear Linda£¬
   I'm glad to receive your letter asking for my advice£®From your letter£¬I know that your parents don't agree with your idea that you want to travel alone this summer£®£¨ÁÁµã¾äÐÍÒ»£©
  I guess the reason why they don't agree with you is that they are concerned for your safety£®£¨ÁÁµã¾äÐͶþ£© Perhaps they may think you're too young to travel alone£®Besides£¬they'd like you to make use of this summar holiday to improve your study£®
  In my view£¬it's a good idea for teenabers to travel alone£¬for traveling not only helps us ease our mind but also make new friends and experience new culture£®Here are my tips for your reference£®First£¬it's important to have a talk with your parents and persuade them you are old enough to manage things properly£®Second£¬if they agree£¬you'd better make a detailed plan for your travel in advance£¬including your destination and your means of transportation£®If they still do not agree£¬you'd better show respect for them£®
  Anyway£¬I wish you a pleasant summer holiday£®
      Yours truly£¬

20£®Lead poisoning £¨Ç¦Öж¾£©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£®

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£¨òüºÏ¼Á£©is given to the children£®Sometimes£¬children are given an injection£¨×¢É䣩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£¨±ÈÀý£©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£®
