Step4. Consolidation

1. Recall the story of Matt Myles and have a free talk.

Matt Myles, 27, from Hereford, was working hard on night shifts in a factory when a EuroMillions ticket he bought made him gain ￡100,000. And he wasted no time in putting his surprise wealth to good use --- flying to Indonesia before the

money hit his account. Mr Myles took off on his round-the-world tour in April, taking his brother Pete, 26, along for the ride and picking up his bills. So far his generous lifestyle has taken him to Hong Kong, Bali and Thailand. He then set off for Brazil, where England's disappointing World Cup performance failed to destroy their experience.

Still on his tour list are visiting Machu Picchu in Peru, diving at Australia’s Great Barrier Reef(澳大利亚大堡礁), bungee jumping into the Grand Canyon in Arizona, driving across Route 66 in a Ford Mustang. He then hopes to go boating in the Amazon, walking the Great Wall of China and seeing the pyramids in Egypt and volunteer with UNICEF(联合国儿童基金会) in Africa for three months。

Mr Myles, who used to serve in the Army, told Sunday People，“From travelling the world to meeting celebrities，

I couldn’t have made these things up in my wildest dreams. They say money can’t buy happiness but I have never been happier.”

He said, “Before the shock win, I was working night shifts and was worried I’d have to move back home to save some money. While the next 12 months will be incredible, I won’t change. I’ll live as I always have –

go big or go home!”

However, despite spending his winnings on the main hobby, Mr Myles says he has set himself a limit of ￡10,000. Upon winning, he invested half of the cash in establishing a new business with his friends, and he hopes to be trained as an airline pilot. Free talk: If you were Matt Myles, what would you do?

2. Appreciate one part of the poem and translate another part of it.

If you were only one inch tall,

倘若你只有一寸高，

you'd walk beneath the door,

便能穿越门下的缝隙，

And it would take about a month to get down to the store. 而要行至商店则需要花上一个月的时间，

A bit of fluff would be your bed,

一小撮绒毛能变成你的温床，

You'd swing upon a spider's thread,

你能在一根蜘蛛丝上玩秋千，

And wear a thimble on your head

头上戴着顶针作为头盔，

倘若你只有一寸高，

便能骑着一条小虫去上学。

蚂蚁哭泣时的一滴泪(teardrop),

将成为你的游泳池。

一点蛋糕屑( crumb) ,

能变成一场盛宴，

足够你至少吃上七天，

一只跳蚤( flea)就会是一头可怕的猛兽( beast). __________________________________________________________
