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 Paulos 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 couldnt 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 couldnt 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

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.

Answers: 161012748113592

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 hadnt 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.

重点难点讲解

辨析catch fire, be on fire, set fire to, get burnt

　　catch fire“着火”，着重强调动作。

　　be on fire“烧着”，着重强调状态。

　　set fire to “点燃”，“放火烧”，着重强调动作。也用set…on fire来表达这一意义。

　　get burnt 指“烧伤”，“烧着”。强调结果。

　　Don’t let your dress catch fire. 别把衣服烧着了。

　　The house is on fire. 房子着火了。

　　The enemy set fire to our buildings. == The enemy set our buildings on fire. 敌人放火烧了我们的房子。

　　Dont play with fire; you may get burnt. 别玩火，你会烧伤的。

辨析be out, put out, go out

　　三者都可以表示火或灯的“熄灭”。

　　be out表示“熄灭”的状态，还可以表示“在外面”，“不在家”。

　　go out指“灯，火”熄灭，是不及物动词短语，主语是灯或火等。也有“出去”之意，强调动作。

　　put out指“熄灭”灯火，是及物动词短语，其宾语只能是表示灯火一类的词。例子如下：

　　The light in the room is out. 房间里的灯熄了。

　　His son is out in America. 他的儿子远在美国。

　　One of the plane’s engines went out. 飞机的一个发动机灭火了。

　　She put the fire out and went to bed. 她熄灭炉火后上床。

如果指第几层时，则用floor,同时指每一层室内行走的地面，on the floor 由此而来。floor 英美的表达也不同

first

floor

second

floor

2楼

当表示楼房的高度，说房子有几层时用storey。storey表示上下两层之间的空间。

ground

floor

first

floor

1楼

英国

美国

中国

例子如下：

　　This is a ten-storey building =这栋楼有十层（高）。

　　This is a ten-storeyed building. /This is a building of ten storeys./The building is ten storeys high. 

　　I live on the first floor.(美)  I live on the ground floor.(英)我住在一楼。

辨析collect，gather

　　gather把分散的东西集中在一个地方，例如收集庄稼，树叶，花草等。

　　collect按计划或为了某个特定的目的把东西经过仔细挑选后收集起来。

　　She gathered the fallen leaves.她把落叶扫拢。

　　He collected facts to prove the theory.他收集资料以证明理论。

注意：表示一般意义的“收集；聚集”时，collect 可用来代替gather,但gather不能代替collect以表示特殊意义。

　　I enjoy collecting stamps.我喜欢集邮。（这里的collect 不能用gather来代替。）
