大象是现存世界最大的陆栖动物，主要外部特征为柔韧而肌肉发达的长鼻和扇大的耳朵，具缠卷的功能，是象自卫和取食的有力工具。象肩高约2米，体重3～7吨。非洲象耳大，体型较大，体重较重。亚洲象耳小，身体较小，体重较轻。
大熊猫最奇特的一点是新生儿在出生时相当的不成熟，体重仅是它母亲体重的0.1%，平均为145克左右，约为成年的千分之一。照顾孩子是一项非常艰巨的任务，通常历时18个月，有时长达两年，直到她的下一个孩子出生。

Reading Tips
阅读时，可根据阅读任务的不同，综合运用略读(skimming)与扫读(scanning) 。提高快速阅读水平。
Skimming and scanning
Skimming and scanning are tw fast reading skills t help t brwse text and extract the key pints. The skills require practice, but nce yu have gt the hang f them yu’ll find yu can get thrugh a substantial amunt f reading in quite a shrt time. These reading methds make it easier fr yu t grasp large amunts f material, especially when yu're previewing. They are als useful when yu dn't need t knw every wrd.
略读(skimming)只看文章标题、下标题以及每个部分或者段落第一行，关注文章中反复出现的关键词。略读时，要用充足的时间读懂段落的第一句和第二句，因为第一句往往是该段的主题句(tpic sentence)，而第二句往往是对前句的延伸(extensin)或进一步的解释(explanatin)。
运用扫读(scanning)迅速浏览从第三句开始的后面部分,搜寻作者对开头两句的支持句(supprting sentences),并同时注意文章中间是否有转折词(transitin),因为这些词常常会把文章的思路逆转或加入其它重要的信息。当读到段落的最后一句时,我们又要使用略读,这时必须再次放慢速度(slw dwn yur pace)直到完全消化作者对段落的小结(cnclusin),因为该小结有可能与主题句截然相反或引导读者进入下一个段落。

3. At 9:00 a.m., they find that mst f the babies are already awake and hungry.

注意：awake不用于名词之前，因此用作定语时要后置。

另外，awake不与very搭配使用，表示“完全醒来；十分清醒”用fully awake，wide awake。如：
