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-ing，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。open的现在分词怎么变你知道吗?,本课重点：1.there

不定冠词用在表示数量、时间等名词前，表示“每一（单位）的价格、速度、顺序等”泛指是指首次提到的，不限定的人或事物。特指是指在上文已提到的人或事物，或是指被限制性修饰语在其后加以限定意义的人或事物也可以是指说话者双方心目中所默认的特指的人或事物。,There be句型,There be句型是常见的表示“存在”的句型。该结构不表示“存在”意义的现象又广见于书面语及口语，它以否定句的形式出现，用于对某一具体行为和抽象概念的否定。1、定义：There be句型表示某处存在某物或某人。2、结构：(1)There is+单数可数名词/不可数名词+地点状语.(2)There are+复数名词+地点状语.,There be+sth+地点状语（介词短语）There is a flower in the bottle.瓶里有朵花。There is some money in the purse.包里有些钱。【不可数名词be动词用is】There are some books on the desk.桌上有些书。【可数名词be动词用are】句子的主语是某人或某物，谓语动词be要与主语（某人或某物）的数保持一致。当主语是两个或两个以上的名词时，谓语动词要与跟它最近的那个名词一致。【就近原则】There is a bird in the tree.树上有一只鸟。There is a teacher and many students in our classroom.我们教室里有一位老师和许多学生。There are two boys and a girl under the tree.树下有两个男孩，一个女孩。,一：各种句型转化。1：变成否定句There be句型的否定式的构成和含有be动词的其它句型一样，在be后加上not或no即可。注意not和no的不同：not是副词，no为形容词，not a/an/any+n.相当于no+n.。例如：There are some pictures on the wall.There arent any pictures on the wall.=There are no pictures on the wall.There is a bike behind the tree.There isnt a bike behind the tree.=There is no bike behind the tree.2：变成一般疑问句There be句型的一般疑问句变化是把be动词调整到句首，再在句尾加上问号即可。但同时要注意：当肯定句中有some时，要将其改为any（否定变化也一样）。There is some water on Mars.Is there any water on Mars?There are some fish in the water.Are there any fish in the water?,3：特殊疑问句对主语提问：当主语是人的时候，则用who 引导，当主语是物的时候，则用what 引导。注意：无论原句的主语是单数还是复数，对之提问时一般都用be的单数形式(回答时却要根据实际情况来决定)。如：There are many things over there.Whats over there?There is a little girl in the room.Who is in the room?对地点状语提问：则用where 引导。如：There is a computer on the desk.Where is the computer?There are four children on the playground.Where are the four children?对数量提问：般有两种句型结构：How many+复数名词+are there+介词短语？How much+不可数名词+is there+介词短语？二：there be 句型的时态。be可以有现在时（there is/are）、过去时(there was/were)、将来时(there is/are going to be或there will be)和完成时(there have/has been)；还可用there must be,there cant be,there used to be等。,练习,变成疑问句并作否定回答，和否定句。There is a cup on the table.疑问句：否定回答：否定句：用a，an，the填空Give me _book.Which book?_book on the desk.,There
