It covers five and a half million square kilometers of the Amazon Basin and spreads across nine countries.亞馬遜雨林位于南美洲，是世界上最大的熱帶雨林。它覆蓋伍佰伍拾萬平方公里的亞馬遜盆地，橫穿九個國家。The Amazon rainforest is very important because it is home to thousands of animals, birds and insects. However, people are destroying the area by cutting down many of the trees. This is called―deforestation. Many living things lose their homes because of deforestation. As a result, the number of kinds of animals, birds, insects and trees in the world is decreasing.亞馬遜雨林非常重要因為它是成千上萬的動物、鳥類和昆蟲的家園。然而，人們大量砍伐樹木的行為正在毀壞這個地區(qū)，這就是所謂的“毀林”。因為毀林，許多生物失去了它們的家園。結果，世界上動物、鳥、昆蟲和樹木的種類都在減少。We must do our best to protect the Amazon rainforest.我們必須盡全力保護亞馬遜雨林。 Unit 5 Facts about water 關于水的資料Here are some interesting facts about water:這兒是一些關于水的有趣的資料：About 70% of the human body is water.人體大約30%是水。Oceans cover about 75% of the Earth, but ocean water is salty.海洋覆蓋了大約75%的地球，但海水是咸的。Therefore most of the water in the world is not drinkable.因此，世界上大部分水是不可飲用的。Groundwater may be drinkable, but it is not easy to find groundwater that is clean and safe to drink.地下水也許是可飲用的，但是找到干凈而且安全的地下水并不容易。If water drips from your tap every 10 seconds, you will waster about 315 litres of water a yearenough to fill two baths!如果你的水龍頭每十秒鐘滴一滴水，你每年就會浪費315升水足以填滿兩個浴缸。Having a bath uses about twice as much water as taking a shower.Having a shower instead of a bath can save up to 400 litres a week.盆浴的用水量是淋浴的兩倍。淋浴代替盆浴可以每周節(jié)省400升的水。 Unit 6 Electricity safety tips 安全用電提示 Electricity makes our lives easier.
