课文分析

　　这是一篇记叙文，记述了圣保罗大火的起因、火灾所造成的损失、营救工作艰难的原因等。本文主题突出，首尾呼应，结构如下：

　　Part 1 (Paragraph 1) On Feb. 4th, 1974, a fire destroyed Sao Paulo's newest building, the Capital Building, and killed 220 people.

　　Part 2 (Paragraphs 2-5) The details of the fire

　　(Paragraph 2) The fire broke out on the 11th floor by an electrical fire.

　　(Paragraph 3) More than 300 people were trapped above the I fire.

　　(Paragraph 4) About 70 people escaped from the fire in the helicopters.

　　(Paragraph 5) The firefighters couldn't get close to the people trapped in the fire.            Part 3 (Paragraph 6) The fire lasted about 4 hours.

　　本文围绕 when, where, what, why, how long 等问题，讲述了圣保罗大火的来龙去脉，主要内容如下：

　　On February the 4th, 1974, a big fire broke out, which destroyed the newest building in Sao Paulo and the cars, which belonged to the office workers in that building.

　　Perhaps the fire was caused by an electrical fire of an office on the 11th floor. The office workers tried to put out the fire but they couldn't control it.                                                           

　　The people below escaped into the street but 300 people above the 11th floor were trapped. There were no fire escapes in the building. Some people climbed to the flat roof of the building. But the smoke was too thick for the helicopters to rescue them. In the street there were so many people that the firefighters couldn’t get close to the building and the ladders were not long enough to reach people. So the fire lasted four hours and 220 people were killed in the fire.

听力分析

Step1.Preparation for listening.

　　在未听之前，教师让学生看P122页的练习

Setp2.Play the tape and do exercises

　　At first, play the tape until the Ss could understand it. Then play again do some exercises.每题先放一遍，提问学生大概的内容。然后再放两遍，让学生做练习。

Setp3.Repeat the Dialogue

　　Let the Ss completely and repeat some of the paragraphs让学生能够复述其中的一段,如：

　　I went to see if it was a real fire. There were flames coming out of the ceiling. I quickly went back to my desk to collect my bag, which had in it my house keys, my car keys, and quite a lot of money, as I had been to the bank earlier that morning. It was a Friday, you see, and we were going away for the weekend.

写作分析

Step I Understand the meaning of the words

　　firewood and bedclothes, bedclothes = sheets, blankets and so on for a bed (not the clothes a person wears in bed).

Step II Tell the Ss to read all the sentences first, then to number them in the correct order.

Step III Get the Ss to write a short passage

　　using conjunctions or adverbs when necessary. Here is a model:

　　Last year we went to stay in a small house in the country. When we arrived at the house, it was raining. The house was cold and the bedclothes were not dry. We collected some firewood from the wood and lit a large fire. Then /Next we put the bedclothes in front of the fire to dry them. After that we went into the village to buy some food from the village shop. As we were walking home, we saw smoke coming over the hill. We thought that the smoke was coming from the chimney. However when we got near the house, we saw that the smoke was coming from a window. The bedclothes that were drying in front of the fire had caught fire. Luckily the floor was made of stone, so the house hadn't burnt down. Sadly all the bedclothes had been destroyed in the fire.

　　Get the Ss to check their answers in pairs, then check with the whole class.
