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 (油漆层剥皮). 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 cause mental dullness and a low IQ 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 six should 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 from 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.

Dealing with conflict in the workplace is rarely easy. Hurt feelings and anger can lead to lower employee morale (士气) as well as a loss of productivity and a poor work environment. As a manager. you should find some ways yourself to solve the conflict. The goal is to build a team-centered workforce.

　　　 You can use role-reversal (角色转换) methods to help each employee understand how the other feels. This model works best when there are only two parties involved. You can hold a meeting with annoyed workers in your office. You might say. "Jane, explain to me how you would feel if Nancy went to lunch with your clients (客户 ) without telling you?" Or. "Nancy, how would you respond if Jane came to me with complaints about you, but hadn't tried to talk to you about them first? "

Workers often respond better to praise than criticism. By publicly drawing attention to employees who have healthy work relationships. you can increase the awareness for those who encourage any conflict. Avoid mentioning teams or departments that are being troubled by conflict. Instead. focus on the teams that work well together You might say. "I want to express thanks to the design team for working together to meet the deadline this week," or -Special thanks to the finance department for their teamwork in making sure that the quarterly reports were accurate"

And help your employees see that differences can be good and don't necessarily lead to anger or disagreement This is one of the best ways to settle workplace conflicts. You can meet with employees and try to stress the value of different techniques. This lets all parties know that their own styles can be effective. You might say. " I know you disagree on how to market our services. but when you combine Jim's email marketing with Joe's personal one-on-one phone calls, you can increase sales. The two of you go well together. " Or. "I know you have different styles for interacting with clients. but Sally's take-them-out-for-coffee approach works well together with Ann's formal business meeting style Both are necessary for building relationships and getting work done. "

高三英语单项填空简单题查看答案及解析

In every school there is a "top" crowd that sets the pace, while the others follow their lead. For example, the top crowd decides that it is smart to wear bright red sweaters. Very soon everybody is wearing a bright red sweater.

There is nothing wrong with that, except the fact that bright red is not suitable on some people at all.

The situation can even become dangerous, if the top crowd decides that it is smart to drink or to drive cars at 70 miles an hour. Then the people who follow the lead are causing danger to people's lives. They are like sheep being led to the slaughterhouse (屠宰场).

Perhaps you have come across situations like these more than once in your life. In fact, at one time or another you probably did something you knew to be wrong. You may have excused yourself by saying, "The crowd does it." Well, let the crowd do it, but don't do it yourself. Learn to say, "No." Make your own judge (判断). If you know the crowd is planning something with which you disagree, have the courage to leave them politely. You'll have the satisfaction of standing on your own feet.
