短语可以分为名词短语、动词短语、形容词短语、副词短语、介词短语。下面分别谈一谈它们的用法和构成。一、名词短语：名词短语是由名词和它的修饰语构成的。名词短语主要在句中作主语、表语和宾语。根据名词和修饰语的位置可分为前置定语和后置定语。一般来讲，名词短语构成的“左二右六”指的是二个前置定语和六个后置定语。
1．两个前置定语分别为：限定词和形容词。限定词包括冠词、指示代词(this/that/these/thse)、形容词性物主代词、所有格等。如：the girl，this bk，these cars，my friend，Tm’s father等。2．六个后置定语分别为：(1)介词短语The by in blue is my brther.
(2)分词The by wearing blue jeans is my brther.(3)不定式The building t be cmpleted this mnth is ur schl library.(4)形容词短语The students present in the classrm ttaled 54．(5)定语从句I like ur teacher wh is very kind.
(6)同位语从句The fact that she is gd at English makes her the right persn fr the jb.此外，还有一类由“名词＋介词＋名词”构成的短语在句中常用作状语。这类结构中的名词是同一个名词。如：hand by hand，shulder t shulder，face t face，day by day等。
二、动词短语：动词短语主要在句中作谓语。其构成有六种方式：1．不及物动词＋副词。 如：stay up(熬夜)，lk ut(小心)，break ut(爆发)，g up(上升，爆炸)，take after(像)，die ut(灭绝，消亡)，set ut(出发)。2．不及物动词＋介词。 如：break int(闯入)，g after(追求)，g thrugh(经历)，pass n(传递)，run int(碰上)，sit fr(参与)，stand fr(代表)。
3．及物动词＋副词。如：give up(放弃)，(送行)，(带领参观)，(转交，移交)，(推迟)，(接人；学会)。4．不及物动词＋副词＋介词。如：put up with(忍受)，stand up t(勇敢面对)，d away with(废除)，fall back n(求助于)，live up t(达到，不辜负)。
5．及物动词＋名词＋介词。如：make fun f(取笑)，take care f(照顾)，pay attentin t(关注，注意)，catch sight f(看见)，take n ntice f(没注意到)。6．动词＋动词＋介词。如：make d with(将就用)，let g f(置之不理)。
三、形容词短语：形容词短语主要在句中作定语、表语、宾语补足语等。形容词短语是指由几个形容词或形容词及其修饰语构成的短语。其构成方式主要有：1．三个或三个以上的形容词同时修饰一个名词，并且放在它们所修饰的名词之前。This splendid ancient Chinese building is still kept in gd cnditin.这一壮丽的中国古代建筑仍然保存完好。
2．两个形容词可以由and，but等并列连词连接，构成形容词短语。He is yung but clever.他年轻但聪明。Yur rm is large and beautiful.你的房间大且美丽。
3．very等程度副词作修饰语，可与形容词构成形容词短语。It is very ht tday.今天很热。The rad is lng enugh.这路够长的。(lng enugh是形容词短语，enugh在形容词后作修饰语)The rm was awfully dirty.这屋子太脏了。
4．介词及其宾语可用在形容词后修饰形容词，可与形容词构成形容词短语。I’m sure f success.我确信会成功的。(sure f success是形容词短语．)The bttle is full f water.瓶子里装满了水。(full f water是形容词短语)5．不定式在形容词后作修饰语，可与形容词构成形容词短语。He is sure t cme.他一定会来。
四、副词短语：副词主要是用来修饰动词、形容词、其他副词及句子的词，通常用来表示时间、地点、程度、方式等。而副词短语指的是由不止一个词组成、但整个短语的功能/作用相当于一个副词的短语。副词短语通常在句中作状语，一般有以下几种构成：1．两个或多个副词可以由and，but等并列连词构成副词短语。如：again and again。
2．程度副词作修饰语，可与其他副词构成副词短语。如：clearly enugh，much faster，extremely quickly，rather slwly。3．介词及其宾语可与副词连用，与副词构成副词短语。如：back t nrmal。4．不定式或不定式短语在副词后作修饰语，可与副词构成副词短语。如：early t rise。
5．名词与副词构成副词短语。如：hands backwards(背着手)。6．副词与表示比较的结构可构成副词短语。如：as carefully as。五、介词短语：介词又叫前置词，一般置于名词、代词或相当于名词的词语之前，一起在句中作状语、定语、表语，有时也用来构成复合宾语。介词一般不重读，不单独作句子成分，只表示它与后面的词和其他句子成分的关系。介词短语可以分为五类：
1．简单介词＋名词/代词。如：fr tw years，frm the bus stp，t schl，n the table，at the end等。2．复合介词＋名词/代词。如：int the hall，utside the huse，upn ne’s arrival，withut delay等。3．二重介词＋名词/代词。如：frm behind the dr，until after schl，frm amng the trees等。
4．分词介词＋名词/代词。如：regarding his hbby，including Mike，cncerning ur future pay等。5．短语介词＋名词/代词。如：alng with his friends，n behalf f all the students，wing t the heavy rain，in spite f his shrtcming，n accunt f his delay等。
