新版上海牛津版七年级上册unit4知识点及练习
1、知识点
1．形容词常放在名词前来修饰名词,即“怎么样的….”,作定语.
eg:
an apple----an red apple
a day----a sunny day
cartoons----interesting cartoons
streets----busy and noisy streets
注：
①有形容词修饰的名词叫名词词组,名词词组的构成是“冠词、数词+ 形容词+ 名词“
②两个形容词之间可用and连接
【跟踪练习】
一个漂亮的老师__________________
这只很肥的猪____________________
两个又红又大的苹果____________________
二：
形容词放在be动词后,构成“sb/ sth+ be + adj” 表“…..怎么样”,作表语
eg:
The weather is warm in Spring.
Winter is often cold and snowy.
注：
be动词后面的形容词表明的都是主语的特征,我们还有其他的动词后面也是跟形容词来表明主语的特征：
1. 变得:
get, turn
eg:
In spring, the weather gets warm.
Everything turns green.
2. 感官动词; 看起来（look）,听起来（sound）,闻起来（smell）,尝起来（taste）,摸起来,感觉起来（feel）
eg:
The cake smells delicious.
You look sad.
be动词,感官动词等都统称为系动词
【跟踪练习】
The flower smells _______. （ good ）
The house looks _________. （beauty ）
In autumn ,leaves turn ______. （ 绿色的 ）
It’s getting very _________. （冷的 ）
三：
It is +adj+ to do sth 做某事怎么样
It is nice to eat ice cream in the park.
这个句子真正的主语不是it, 而是整个动词不定式的部分,因此我们把it称为“形式主语”,这个句子也可以写成：
To eat ice cream in the park is nice.
我们很少采用这种形式,因为会显得句子头重脚轻

②少数以不发音的-e结尾的名词变形容词时,去掉-e再加-y
