考点 01
考点1:描述动物特征的句型
例句
It has four legs and a long nose. 它有四条腿和一个长鼻子。
It is black and white. 它是黑白色的。
It eats bamboo and leaves. 它吃竹子和树叶。
It lives in the river. 它生活在河里。
解析:
用"It has..."描述动物外貌特征,has后接身体部位名词(如legs, nose, fur等)
用"It is..."描述动物整体特征,is后接形容词(如big, small, beautiful等)
用"It eats..."描述动物饮食习性,eats后接食物名词(如bamboo, grass, fish等)
用"It lives..."描述动物栖息地,lives后接地点介词短语(如in Africa, on a farm等)
技巧:
1.注意has和is的区别:has描述"拥有什么",is描述"是什么样"
2.食物和地点前要加适当介词:eat后直接加食物,live后加in/on等介词
3.多个特征用and连接,注意形容词顺序(大小+颜色)
