Scientists say there are now fewer than 2,000 pandas living in the forests. Another 300 or so live in zoos or research centers in China and other countries. Pandas do not have many babies, maybe only one every two years. The babies often die from illnesses and do not live very long. Adult pandas spend more than 12 hours a day eating about 10 kilos of bamboo. Many years ago, there were a lot more bamboo forests and pandas in China, but then humans started to cut down the forests. As the forests get smaller and other human activities cause more problems, pandas cannot find enough to eat and they are having fewer babies. 互动课堂(探究与合作) 探究点3：another+数词 观察下面句子, 体会another+数词的用法。 We need another two candles. =We need two more candles. 我们还需要两支蜡烛。 * * ______ + ____ +名词复数 = ____ + ____+名词复数, 表示“又/另 外/再几个”。 another 数词 数词 more * * 【拓展】 another和more与数词连用时, 都表示在原有基础上的增加。但当数词是one时, 可以用one more表示“又一个; 再一个”, 而不用another one。在意义上该用another one的地方, 直接用another。 * 互动课堂(探究与合作) 探究点4：die ,dead, dying与death 的区别 读下列句子, 体会die, dead, dying和death的区别。 1.
