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 6 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(预防) 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 results of lead poisoning.

SECTION B (10 marks)
Directions: Read the following passage. Answer the questions according to the information given in the passage.
Although many Chinese students say that their knowledge of English grammar is good, most would admit that their spoken English is poor. Whenever I speak to Chinese students they always say, "My spoken English is poor," However, their spoken English does not have to remain "poor". 1 would like to suggest that there may be some reasons for their problems with spoken English.
First, they fail to find suitable words to express themselves due to a limited vocabulary. Obviously the better answer is to expand their vocabulary. However, you can speak with a limited vocabulary, if your attitude is-positive. Others will follow you as long as you use the words that you know.
Second, they are afraid of making mistakes. Sometimes they make mistakes when they are speaking because they are shy and nervous. Yet students should remember that their goal should be FLUENCY NOT ACCURACY. Your aim in writing is to be accurate following the rules for grammar and using the right words and spelling them correctly. However, in speaking, your aim is fluency. You want to get your message across, to talk to someone in English as quickly and well as you can even though sometimes you may use a wrong word or tense. But it doesn't matter because the person you are speaking to will understand you and make allowances for any mistakes he hears.
The third reason is that not enough attention is paid to listening. You have one mouth but two ears! All that hearing is necessary for you to start speaking.
Fourth, most Chinese students are reactive rather than proactive(积极主动的)language learners. Instead of actively seeking out opportunities to improve their spoken English they passively (被动地)wait for speaking opportunities to come to them and wonder why their English always remains poor. If you have this proactive outlook(见解，观点), then; you will see English opportunities wherever you go.
If you do not use your English beyond the classroom you will forget that English you know. Remember: USE IT OR LOSE IT! You can learn how to speak English better by speaking English more.
