L47-1: Too high a price?

ɛl47-1: tuː haɪ ə praɪs?

Pollution is the price we pay for an overpopulated, over industrialized planet. When you come to think about it, there are only four ways you can deal with rubbish: dump it, burn it, turn it into something you can use again, attempt to produce less of it. We keep trying all four methods, but the sheer volume of rubbish we produce worldwide threatens to overwhelm us.

Rubbish, however, is only part of the problem of polluting our planet. The need to produce ever-increasing quantities of cheap food leads to a different kind of pollution. Industrialized farming methods produce cheap meat products: beef, pork and chicken. The use of pesticides and fertilizers produces cheap grain and vegetables. The price we pay for cheap food may be already too high: Mad Cow Disease (BSE) in cattle, salmonella in chicken and eggs, and listeria in dairy products. And if you think you'll abandon meat and become a vegetarian, you have the choice of very expensive organically-grown vegetables or a steady diet of pesticides every time you think you're eating fresh salads and vegetables, or just having an innocent glass of water!However, there is an even more insidious kind of pollution that particularly affects urban areas and invades our daily lives, and that is noise.

知识笔记：

今日音标

/p/：是一个爆破音；发音时，首先紧闭双唇阻止气流流出，突然分开双唇，气流冲开口腔，同时发出爆破的声音；发音时，声带不振动；发这个音时千万不要在后面加一个弱读的/ə/。

/b/：首先紧闭双唇阻止气流流出，突然分开双唇，气流冲开口腔，同时发出爆破的声音；发音时，声带振动；发音时送气力量较弱。

练习感悟：看了S老师的新书，选择发音作为学英语的突破。集中精力突破这一点。
