The smog① from the fire has already caused hundreds of deaths and illnesses. Our reporter, Penny Wang, is there and has this report.① smog n. 烟雾3456788-2It’s now just three in the afternoon, but it seems like night-time. A thick smog is covering most of the countries in South-east Asia. Many people are wearing masks to cover their mouths and noses. Thousands are suffering from eye or breathing problems. One doctor told me that living in this smog is like smoking 600 cigarettes a day.The fires are still burning. There are 8,500 firefighters trying to put out the fires, and another 2,000 are coming from around the world to help them. But the fires are too big to put out. The only thing that can extinguish them now is lots of rain—and rain is not expected for several weeks.123456788-3Penny, can you remind us how these terrible fires started?Well, most of the fires were started by farmers. They wanted to clear the land before they planted new fields. But this year things are much worse than usual. Some big companies bought large areas of land. They are using fires to clear them quickly so that they can plant rice, palm oil trees or rubber trees. Second, a drought started many months ago so the land is very dry.123456788-4Penny, you’ve told us about some of the effects of the fire on people. What other problems are the fires causing?Well, there are almost no tourists here at the moment. Also, the smog has caused some bad accidents. But the most serious problem is that the fire is destroying the forests. As you know, trees take harmful gases from the air, and release oxygen. They are very important to the world, and now millions of them are burning.I hope the fire will be put out soon.123456788-5 Find the words and phrase in Column A in the passage on page 14 and match them with the meanings in Column B.Aecdba123456788-6 What does the word ‘them’ refer to in each of these sentences?
