Finally, I'd like to conclude _ _ showing this slide.8 Thank you all _ _ coming. Any questions?2't,{Read this email enquiry. Write a reply, using the presentation notes below to help youanswer the questions.Hi Karl,It was great to meet up with you at the conference last weekend. I'm interes ed inwhat you were saying about incineration as a way of dealing with waste. I have somequestions for you.

Please could you email me some brief answers?1 Why is waste such a big problem?2 What benefits does incineration bring?3 Aren 't people worried about pollution from incinerators?4 What does the process of incineration involve?5 Why do you say that it's an advantage to site incinerators in cities?Best wishes ,BullentPresentation notesIncineration converts waste materials -7 bottom ash , flue gases, particulates and heat. Heatused for space heating and/or electricity generation.Waste is bulky; incineration reduces mass of waste by 80-85%.Show slide: moving grate incinerator. Continuous process: waste enters at one end; ashleaves at the other end.

Heat transformed into steam -7 drives the turbine. Flue gases arecooled -7 pass through the flue gas cleaning system.Bottom ash from the incinerator - non-hazardous. People worried about pollution fromincinerators. Improved emission control: pollutants in the flue gas reduced by particlefiltration, using electrostatic precipitators. Heavy metals, e.g.

mercury, lead, chromium,removed by acid gas scrubbers.Show slide: Incinerator in city centre. Emission control better in modem inc inerators.Convenient for reception of waste, and for output of space heating and electricity. Canincrease electricity generation in summer or space heating in winter.Hi Bullent,Many thanks for your email asking about incinerators.

I'll try to answer ...RE'\ IE'\\331 Statements1Underline the correct phrases. There may be more than one possible answer.I I said the official / to the official / (NO WORD) that I had a metal plate in my hip.2 He told me / to me / (NO WORD) the airport had put in new security procedures.3 I informed the clerk / to the clerk / (NO WORD) that I had packed my case myself.4 She reported me / to me / (NO WORD) that there had been a security breach.5 She explained him / to him / (NO WORD) that the X-ray machine didn't harm laptops.6 She promised him / to him / (NO WORD) she would phone as soon as she arrived.7 He confirmed me / to me / (NO WORD) that he had orders to carry out a manualsearch.8 He assured them / to them / (NO WORD) that there would be a full investigation.2 Complete the table below with the reporting verbs in the box.say tellinfonnreportexplain1 verb + objectpromiseconfinnassuretell2 verb + to + object OR with out object3 verb + object OR with out object3 Write what the security inspector actually said, using direct speech.Example: 1 'The airport has introduced a new scanning system.
