Module 1Travel基本思路：M1U3 Language in use 第二课时冠词冠词分为不定冠词a/ an和定冠词the，在具体使用时可分为用不定冠词、定冠词和不用冠词三种情况。它的基本用法我们可以用以下口诀来记忆： 泛指用a/ an，单数可数；特指用the，不特不the。 一. 用不定冠词的情况： 单数可数名词前用到不定冠词a/ an时，一定要根据它后面单词的首音素来判断。a接以辅音音素开头的单词或字母，an接以元音音素开头的单词或字母。如： a book, a Japanese car, an egg, an hour（h不发音），an “s”（字母s的首音素为e），a“u”（字母u的首音素为j） 二. 用定冠词的情况： 定冠词the的用法很多，也较复杂，因此同学们常常出错。其实the的用法可以用以下口诀来记忆和理解： 特指双熟悉，上文已提及，世上独一无二，序数最高级，某些专有名，习语及乐器。 注（1）the用在“特指”谈话双方都知道的某个人或某些人或物前。如： Where is the teacher？ 老师在哪里？ （2）the用在上文已提到的人或事物前。如： I can see a cat. The cat is Lucy”s. 我能看见一只猫，那只猫是露茜的。 （3）the用在世界上独一无二的事物前。如： The earth goes around the sun. 地球围绕着太阳转。 （4）the用在序数词或形容词最高级前。如： Mike is the tallest of the three boys. 迈克是三个男孩中最高的一个。 （5）the用在由普通名词构成的专有名词前。如：the Great Wall（长城），the People”s Park（人民公园 ）等。 （6）the用在一些习惯用语中或乐器名词前。如：in the day（在白天），play the piano（弹钢琴）等。三. 不用冠词的情况： 以下口诀可以帮助我们记忆名词前不使用冠词的情况： 代词限定名词前，专有名词不可数，复数名词表泛指，学科球类三餐饭，季节星期月份前，颜色语种和国名，称呼习语及头衔。 构成。如： four hundred， five thousand， seven million， nine billion 注意：几百几十之间一般用and连接。如： three hundred and forty- nine， six hundred and seven表示不确定的“数百”，“数百万”，“数千”，“数十亿”时，用“hundreds”，“thousands”，“millions”，“billions”加“of”构成。如： There are hundreds of teachers in our school. Thousands of students are studying in our school. The mountain is covered with billions of trees.表示顺序的词（序数词）除1-3外，其余的后面都有后缀-th。如： first， second， third，fourth， fifth， ninth， eleventh， twelfth整十的序数词后面是由基数词变y为i，再加eth构成。如： twenty twentieth， eightyeightieth， ninetyninetieth 其余的整数加个位数构成的词，只变个位数为序数词即可。如： twenty-ninetwenty-ninth，forty-fiveforty-fifth，fifty-sixfifty-sixth，sixty-sevensixty-seventh，ninety-seven ninety-seventh序数词前一般加定冠词the，但有时加不定冠词表示“又一”，“再一”等。如：I have tried twice. I want to try a third time.He has failed three times. He will try a fourth time.数词与名词连用时，如几号，几班，几年级，房间号及邮编号码时，首字母都大写。如： Number One， Class Three， Grade Two， Room 218， Zip Code 257091表示倍数的大小时，两倍用twice表达，三倍以上用数词加times表达。如： My school is twice as large as theirs.
