L47-1: Too high a price?
?l47-1: tu? ha? ? pra?s?
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.

知識筆記：
今日音標(biāo)
/p/：是一個爆破音；發(fā)音時，首先緊閉雙唇阻止氣流流出绵脯，突然分開雙唇厌衔，氣流沖開口腔罢荡，同時發(fā)出爆破的聲音屋厘；發(fā)音時，聲帶不振動旺芽；發(fā)這個音時千萬不要在后面加一個弱讀的/?/沪猴。
/b/：首先緊閉雙唇阻止氣流流出，突然分開雙唇采章，氣流沖開口腔运嗜，同時發(fā)出爆破的聲音；發(fā)音時悯舟，聲帶振動担租；發(fā)音時送氣力量較弱。
練習(xí)感悟：看了S老師的新書抵怎，選擇發(fā)音作為學(xué)英語的突破奋救。集中精力突破這一點(diǎn)。
