Many experts blame climate change and loss of habitat,normal growth area,for damaging plant life.They say human activities and poorly planned,overly heavy use of land also are responsible.

许多专家将植物物种的破坏归咎于气候变化及生境和正常生长区域的减少。他们称人类活动及对土地的糟糕规划和过度使用对此也是造成上述问题的原因。听力破解loss of属于辅音因素结尾+元音因素开头,因此要连读为[′lɔsəv]。

词汇宝典:blame表示“责备,指责,归咎于”,如谚语:A bad workman always blames his tools.拙匠总怨工具差。blame的常用结构为blame sb.for sth.或者blame sth.on sb.,如:She blamed him for the failure of the test.=She blamed the failure of the test on him.她把考试失败归咎于他。

听力破解:starvation中的st的发音[st]要浊化成[sd]。

词汇宝典:water的常见意思是“水”,water也能作动词表示“浇水”,如:water a flowerbed“给花坛浇水”。在中文里,给植物和动物水时使用的是不同的动词,但是在英语里通用water,如:water the horses饮马。

粮农组织称,已知现存植物种类为大约25万种,其中有3万种植物可以食用。不过,已被人类用作食物的只有7000种。

如:

2.treat...with对待;处理

▶treat 有“宴请;款待”的意思,如,在西方的Halloween(万圣节)前夕,孩子们挨家挨户地敲门索要糖果时就会说Trick or Treat(不请客就捣乱)。

▶treat 还可以表示“对待;处理”,如:

You should treat her with more consideration.你应该多体谅她一点。

▶treat 还有“协商;谈判”的意思,如:

The government refuses to treat with terrorists.

政府拒绝与恐怖分子谈判。
