7、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-o

8、ld）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：Hes the happiest man on earth. 他是地球上最快乐的人。The 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：These subjects reflect our daily lives. 这些题材反映我们的日常生活。This medicine is for ex

10、it 深灰色的套服4. 强调形容词 有些形容词起强调作用，如：Its an utter mystery. 这完全是个谜。I have perfect trust in his judgement. 我绝对信任他的判断力。5. -ing 形容词1）有大量现在分词正在或已经变为形容词，如： It was a tiring journey. 这真是一趟累人的旅行。 This is a convincing argument. 这是个有说服力的论据。这样的形容词多由及物动词变来。有很多也是品质形容词，有时可用于最高级（如most amazing, most disappointing）。2）还有一些形

11、容词和不及物动词有关，如：We hope to lessen the existing tension. 我们希望缓解目前的紧张局势。Hes one of the greatest living composers. 他是当今最伟大的作曲家之一。这类形容词只能作定语，不能用于比较级。3） 还有一些-ing形容词并不与动词有关，如：neighbouring cities 邻近的城市 a cunning trick 狡猾的计谋6. ed形容词1）大多数-ed形容词都与及物动词有关，是由它们的过去分词变过来的，一般有被动意义，多数为品质形容词，如： She looked embarrassed. 他

12、好象很尴尬。 These people are from distressed areas. 这些人来自贫苦地区。 I felt depressed. 我感到很沮丧。2） 有些-ed形容词可说是类属形容词，也由动词的过去分词变来，但不能用于比较级，如：You have to pass the required examination to become a doctor. 你需要通过规定的考试才能成为医生。She is a trained nurse. 她是一个受过训练的护士。3）有少数-ed形容词，不是由动词，而是由名词变来的： skilled workers 技术工人 salaried c

14、. 副词+现在分词： low-lying 低洼的e. 名词+现在分词：heart-breaking 令人心碎的f. 形容词+名词： present-day 当代的2）还有一些其他类型的合成形容词，如：a two-piece suit 两件套的西服all-out attempt 全力以赴的努力take-home pay 扣税后的实得工资3）还有一些三个或更多词构成的和成形容词，如： wait-and-see policy 观望政策 heart-to-heart talk 推心置腹的谈话an out-of-the-way place 偏僻之地 an-out-of-date driving lice
