Lead poisoning (鉛中毒) 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 (油漆層剝皮). 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 (神經(jīng)系統(tǒng)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 (螯合劑) 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.

Read the following passage. Answer the following questions according to the information given in the passage.

Abby and Ally are my dear daughters. Last week, we had an outing and we were really tired later that day. After enjoying good food, we headed back. Abby pushed the button as we awaited the elevator and suddenly Ally let out a sigh of disappointment.

“Oh wait, we can’t use the elevator,” Ally said, pointing to a sign near the elevator. Too tired to challenge her, both Abby and I followed her without looking around the corner to another set of elevators. “Oh, my god,” Ally said, visibly upset. “we can’t use the elevators either！They’re also reserved for the firefighters.” Abby looked at me. I looked at Abby. We both looked at the sign and then we stared at Ally to see if she was serious. She was. .

“Ally, the sign doesn’t say the elevators are reserved for firefighters,” Abby explained. “It says not to use the elevators in case of fire！With that, Ally took a longer look at the sign and actually read it instead of skimming it this time.

What’s the lesson here? You have to spend time reading signs, maps or recipes instead of just assuming you know what they say, or you might go through life climbing many flights of stairs when you could be taking the elevator.

It also got me thinking about how often we do this with reading. I wonder how many people just assume they know what a book says instead of actually spending time reading it, thus making wrong assumptions. How often have I neglected a book simply because I think I “know” what it says when I really just need to slow down, open the book, and focus on the reading?

1.Why did Abby believe what Ally said about the first elevator? (No more than12 words)

2.What did the sign really say? (No more than 9 words)

3.How did Ally read the sign at first? (No more than5 words)
