参考:两个英语单词组成的词叫复合词,这样的词去了去了!!
A.复合词的概念—
由两个或更多的词合成一个词的现象,叫复合词,又称合成词(词与词之间可以有连字符);其中以复合名词最多,其次是复合形容词,复合动词、介词、副词、数词等也不少。
B.复合名词
a.名词+名词:bookshop/store/seller/mark,sunlight/shine/glasses,French/Englishman,policeman/woman,volley/basket/base/football,penfriend,grandfather/mother/son/daughter/parent(s)/children,schoolboy/girl/bag/yard,headache/master/teacher,moon-cake/light,team/house/homework,workbook/place/shop,newspaper,motorbike/car,birthday,bed/class/bathroom,handbag,gate-keeper/man,pencil-box,day/lunchtime,lifeboat/time,postcard/man/office,seafood,weekday/end,class/work/mate,northeast/west,railway,southeast/west,textbook,teapot,shellfish,earthquake,cup/keyboard,doorbell,fireplace,farmland,hometown,salesgirl,necklace,wardrobe,spaceship,etc.

II.缩写词
A.缩写词概念B.长单词变短单词网页C.一个首字母即代表一个单词网页
A.缩写词概念—
由一个长单词或二个以上的单词缩为一个短单词(更可简到只剩廖廖几个骨架字母),叫缩写词又名缩略词。
B.长单词变短单词—
a.截头:telephone—phone,bicycle—cycle,aeroplane—plane,etc.
b.去尾:mathematics—math(s),photo-graph—photo,Monday—Mon.,October—Oct.,adverb—adv.(ad.),kilogram—kilo,examina-tion—exam,advertisement—ad.,laboratory—lab,etc.
c.既截头又去尾:refrigerator—fridge
d.混合词(各取两词的一部分刷新成另一词):breakfastandlunch—brunch

C.一个首字母即代表一个单词网页(注:多数要大写,组合成像单词一样的常见缩写词)。如:veryimportantperson—VIP,physicaleducation—P.E等
CD,BBC,CAAC,ID,IQ,IT,UFO,SAR,OK,CBA,MBA,WTO,UNESCO,PLA,PRC,AD,CCTV,CCP,EMS,USA,p.m.,kg,km,cm,mm,a.m.,etc.(注:它们一般按字母读音读,如PC/pi:si/;但像UN-ESCO/ju(:)neskou/等也可当作一个单词来拼读)。

物主代词和冠词为什么不能同时用?

因为它们都是属于“中位限定词”, 在一个名词词组中不可以同时使用两个中位限定词如, 不可以说:
This is my a book.
He Is my the first teacher.
要说:This is a book of mine.He is my first teacher
1、不定冠词 a 和 an,表示泛指某个人或物
a 用於辅音前,an 用於元音前。在 FM、UN 等缩略语前,用 a 还是 an,需视首字母如何发音而定.如 F 是辅音字母,但其发音以 e 开头,故应说:an FM radio.U 是元音字母,但其发音以 j 音开头,故应说:a UN declaration。
2、定冠词the,表示特指某人或某物
1)指已提到或易领会到的人或事。
例如: There were three questions. The first two were relatively easy but the third one was hard. 有三个问题,头两个相对容易,第三个困难。
2)指独一无二的、正常的或不言而喻的人或事物。
例如: the Mona Lisa 《蒙娜丽莎》;
the Nile 尼罗河;
the Queen 女王。
