人教版英语三年级上册 Unit 3 Our animal friends 语法精练
语法点拨
- 动物类名词单复数：表示单个动物用单数（如 a dog 一只狗），表示两只及以上用复数，规则变化：
(1) 直接加 - s（如 cat→cats, bird→birds）；
(2) 以 s, x, sh, ch 结尾加 - es（如 fox→foxes，本单元暂不涉及复杂变化，聚焦基础规则）。
- be 动词用法：根据主语单复数选择 is/are，单数主语（a dog, it）用 is，复数主语（dogs, they）用 are，句型：
(1) 肯定句：主语 + is/are + 其他（如 It is a cat. They are birds.）；
(2) 否定句：主语 + is not/are not + 其他（如 It is not a dog. They are not ducks.）。
- 简单形容词描述：用颜色（black 黑色，white 白色）、特征（small 小的，big 大的）形容词修饰动物，放在名词前（如 a black dog 一只黑狗，big elephants 大象）。
