第7计 不定冠词-秒杀2021年中考英语语法36计

2021年中考英语秒杀技巧七： 不定冠词 本节学习第三步-秒杀不定冠词： 我们只关注选择填空横线后面的单词。 a和an都用于可数名词单数前，泛指人和物。表示可数事物中的一个。但两者用法有区别： （1）若随后的单词以辅音音素开头，用 a。如：a lot of，a good idea，a pear。 （2）若随后的单词以元音音素开头，用 an。如：an example，an orange，an apple。 由于我们很多同学音标学习得不好，在这里会有很大障碍，所以在这里我们只需要记住一些特殊的常考的加a单词（单词首字母A/E/I/O/U开头的单词）： European、university、useful、UFO、U。 其余均认为单词首字母A/E/I/O/U开头的单词加an即可。 而某些以字母 h 开头的单词用an，因为这些单词的＂h＂不发音。如：an honest boy，an hour ago。 惯用短语中的不定冠词 have a good time 玩得高兴 have a look 看一看 have a headache 头痛 have a good sleep 好好睡一觉 go for a walk 散步 take a bath 洗澡 tell a lie 撒谎 wait a moment 等一会 with a smile 微笑着 with an effort 努力地 as a result 因此 once in a while 偶尔 for a moment/ while 一会儿 in a hurry 匆忙地 make a face 做鬼脸 do sb a favour 帮某人忙 take an active part in 积极参加 at a time 每次 as a whole 作为整体 all of a sudden 突然 1．（2020·西藏中考真题）—How do you often communicate with each other? —We often send ________ e-mail or write ________ letter.
