恐龙是距今1亿3千万年前地球上爬行动物的总称。它们的种类很多,身体大小、形状、生活习性各不相同,陆地、海洋、天空都是恐龙类爬行动物的活动场所。大的如中国四川省合川县发现的合川马门溪龙,全身长22米,体高3.5米,体重40~50吨。平时在水深5~10米的湖泊中生活,利用水的浮力浮起笨重的身体,以水中的藻类为食物。小的鹦鹉龙整个身体只有一只小狗大。有的能在空中飞翔,像长尾的喙嘴龙,有尖利的牙齿和长长的尾巴。尾巴末端有一块像苍蝇拍形状的膜,飞翔的工具是翼膜。有的是海中的霸王,如喜马拉雅鱼龙,食肉善游,上下颌特别长,形成长吻,口内有牙齿,外貌很像今天的海豚。有的是陆上的武士,如剑龙,身长6米,头小,背部高拱,有两排三角形的骨板竖立着,尾尖处有骨刺,是御敌的武器。到了1亿3千万年前左右,由于强烈的地壳运动所引起的地形、气候的变化,称霸一时的恐龙在地球上就完全灭绝了。恐龙灭亡的原因至今没有定论,但应看到原因是多方面的、复杂的,是当时外界环境的改变与恐龙内在因素相互作用影响的结果。
恐龙是出现于二亿四千五百万年前,并繁荣于六千五百万年前结束之中生代的爬虫类。或为恐龙和与它同一时代的蛇颈龙、翼龙等的模糊总称。恐龙在某一时期突然消失,成为地球生物进化史上的一个谜,这个迷至今仍无人能解。

Language points
知识点1
如何用形容词最高级来描述事物
课文原句:That's the tallest dinosaur in this hall.
什么时候使用形容词最高级?
比较三者或三者以上的人或事物时会用到形容词的最高级。
注意:在句子中,形容词最高级前面要加the。
三者或三者以上比较,表示“最……的”常用“the +形容词最高级”结构,后跟由of或in开头的表示范围的介词短语。
例句:Lucy is the tallest of the three.
知识点2
如何用”than”做比较
课文原句:It's taller than both of us together.
形容词有原级、比较级、和最高级三个等级,比较级通常用于两个人/物间的比较。than意为“与……相比较”
句型结构:A +be动词+形容词比较级+than B.
例句:Jack is taller than Tom.
Tom
Jack
知识拓展
我们学会了如何来比较两个人或事物,但是当比较有具体的差距时,如短2厘米、大3岁等,该如何表达呢?来看下面的句型公式吧。
A+ + + + +B
am/is/are
具体的差距
形容词的比较级
than
例句:I'm 5 years older than my sister.
知识点3
如何问答身高
课文原句:—How tall are you —I'm 1.65 metres.
句型结构:问句 How tall +be动词+主语
答句 主语+be动词+数字+长度单位(+tall).
例句:—How tall are you
—I'm 1.5 metres.
—How tall is John
—He is 1.6 metres.
be 动词随着主语人称的变化而变化;在表达高度时,后面的tall可省略,长度超过“1”时,要用复数。
Practice
班级小调查:Who is taller than me
