1、New Concept English（Book 1）(新概念英语)（第一册）,-by Stella,音节：,音节是读音的基本单位，任何单词的读音，都是分解为一个个音节朗读。在英语中元音特别响亮，一个元音可构成一个音节，一个元音和一个或几个辅音音素结合也可以构成一个音节。一般说来，元音可以构成音节，辅音不响亮，不能构成音节。但英语辅音字母中有 4 个辅音m，n，ng，l是响音，它们和辅音音素结合，也可构成音节。它们构成的音节往往出现在词尾，一般是非重读音节。英语的词有一个音节的，两个音节的，多个音节的，一个音节叫单音节，两个音节叫双音节，三个音节以上叫多音节。,划分音节的方法：,元音是构成音节

2、的主体，辅音是音节的分界线。两辅音之间不管有多少个元音，一般都是一个音节。如：bed 床，bet 打赌，seat 座位，beat 毒打，beauty 美。两元音字母之间有一个辅音字母时，辅音字母归后一音节，如：student 学生，labour 劳动。有两个辅音字母时，一个辅音字母归前一音节，一个归后一音节，如：letter 信，winter 冬天。不能拆分的字母组合按字母组合划分音节。如：father 父亲，teacher 教师。,巧分音节：一归后，二分开，复音连缀不分开,一归后：在两个音节之间，若只有一个辅音字母（r除外），这个辅音字母划归后一个音节。如dirty:dir-ty.二分开：在

3、两个音节之间，若有两个辅音字母，则分别划归为前后两个音节。如thirsty:thirs-ty.辅音连缀不分开：在两个音节之间的复音连缀或复音字母组合，如th,ph,tr,dr等不能分开，必须划在一个音节内，如果前一个音节是重读闭音节，就划归为前一个音节；如果前一个音节是非重读闭音节或开音节，他们一般划归为后一个音节。如chicken:chick-en,April:A-pril,agree:a-gree.,开音节和闭音节,1开音节 1）以发音的元音字母结尾的单节(辅音+元音)。例：be，he，who，she,go,hi(绝对开单节)。2）以一个元音字母加一个辅音字母（r 除外）+不发音的e结尾的

4、音节(辅音+元音+辅音+e)。例：make,like,same,use,home,drive,these(相对开单节)。*在重读的开音节中元音字母按字母名称读音。2闭音节 以一个或几个辅音字母（r 除外）结尾而中间只有一个元音字母的音节，称为闭音节(辅音+元音+辅音r w y 除外或者元音+辅音r w y 除外)。例：map，desk，is。*在重读的闭音节中元音字母读做短元音。,现在分词的构成规则是:,1.大多数动词直接在词尾加-ing，例如：go-going,work-working,study-studying,look-looking等。2.以不发音的e字母结尾的动词，需去掉e再加-i

5、ng，例如：make-making,write-writing,skate-skating等。3.以重读闭音节结尾，末尾只有一个辅音字母的动词，要双写这一辅音字母，再加-ing。例如：run-running,swim-swimming,begin-beginning,stop-stopping,sit-sitting等。listen/lisn/重读在第一个音节上,不符合第三点,所以他属于规则变化,直接加ing就好了,像travel这种重读不在的vel，可以为travelling，也可以是traveling.重读闭音节三要素：1.必须是重读音节；2.最后只有一个辅音字母；3.元音字母发短元音。o
