冠词a、an的学习与应用【基本知识】冠词a、an的选用以其后单词的读音为准(按音标，而不是字母)。冠词后的单词开头读元音时用an；读辅音时用a.注意以下几种情况：1.单词以“h”字母开头，用an.如：anhour,anhonour,anhonestman等。2.单词以“u”字母开头，由不同的读音决定用an或a.读元音时用an;读辅音时用a.如：anuglyboy,anunknownplace;auniversitystudent,ausefulplant等。3.单词中有特殊读音的情况，如：aone-eyedanimal,aEuropeancity等。4.字母表中的元音字母以及读元音的f、l、m、n、s、x辅音字母的读音也决定a、an的使用。如：anA-shapedbuilding,anX-raytest;a“u”andan“s”等。【学以致用】选用a、an填空：1.Itis____honourtobe____honestchildwhonevertells_____lie.2.Ahorseis______usefulanimal.3.Theboywhohas_____uglyfaceis_____universitystudent.4.Vietnamis______AsiancountrywhileLondonis_____Europeancity.5.Hecomesfrom_____unknowntown.6.Studentsareaskedtowrite______eight-hundred-wordcompositioninChinesetest.7.Ijoinedin_____eight-hundred-meter-longraceandtookfirstplace.8._____“s”、“u”and____“e”makehername“Sue”.9.TheGreenslivein_____A-shapedbuilding.10.Hebrokehisarminthebasketballmatchandhereallyneed_____X-raytest.
