【形容词】
twinings形容词修饰名词，说明事物或人的性质或特征。通常，可将形容词分成性质形容词和叙述形容词两类，其位置不一定都放在名词前面。
1）直接说明事物的性质或特征的形容词是性质形容词，它有级的变化，可以用程度副词修饰，在句中可作定语、表语和补语。例如：hot。
2）叙述形容词只能作表语，所以又称为表语形容词。这类形容词没有级的变化，也不可用程度副词修饰。大多数以a开头的形容词都属于这一类。例如：afraid 害怕的。
按其结构，可分为单个形容词和复合形容词。前者由一个单词（如good, short, happy）构成，而后者则由两个以上的单词（如well-known, kind-hearted, five-year-old）构成。
二、形容词的种类
1. 品质形容词 英语中大量形容词属于这一类，他们表示人或物的品质，如：
He’s the happiest man on earth. 他是地球上最快乐的人。
bmccThe play was boring. 那出戏很枯燥乏味。
You have an honest face. 你有一张诚实的脸。
这类形容词一般都能用于比较级，如 bigger, simpler, younger.
2. 类属形容词 这类形容词表示属于哪一类，如：
The subjects reflect our daily lives. 这些题材反映我们的日常生活。

这类词前面还可加light, pale, dark, deep, bright 等词，如：
light brown hair 淡蓝色头发 a pale green dress 淡绿色裙服
a deep blue skirt 深蓝色的裙子 a dark grey suit 深灰色的套服
4. 强调形容词 有些形容词起强调作用，如：
It’s an utter mystery. 这完全是个谜。

5. -ing 形容词
1）有大量现在分词正在或已经变为形容词，如：
