题型:不详难度:来源:
There is _________ swimming pool in front of Jhon"s house.
A.an 80- metres-long
B.a 80- metre-long
C.80 metres long
D.an 80- metre – long

答案
D
解析

试题分析:句意:约翰家的前面有一个80米长的游泳池。80- metre – long有连词符合的合成词相当于形容词,合成词中的名词不能要复数形式,80是元音音素发音,故用an.
点评:为了读音的方便,在以元音音素开头的可数名词的单数名词前用an而不用a。当我们使用an时,条件有三:①这个名词的读音必须是以元音音素开头--即它的音标的第一个音素是元音,而不是说它是以元音字母开头。②它必须是个可数名词。③它还必须是个单数名词。英语中很多单词是通过合成的方式构成的,他们叫做合成词,常见合成词有合成名词、合成动词、合成形容词等几种类型。这在平时的学习中要多记忆和积累。
