  1. 音标知识点 1.什么是音标？简单的讲，类似于语文的拼音，根据它可以读出这个单词。以后可以根据音标来自学单词。2.什么是元音字母？在26个字母中有5个元音字母，分别是a,e,i,o,u3.什么是长音？在48个音标里，有5个是长音：分别是 （拼音里的a o e i u）4.什么是开音节和闭音节？首先，只有5个元音字母才存在开音节和闭音节的说法。闭音节，音节闭，元音字母生闷气，辅音字母两边堵，元音发音短而促。（例：bag bed big box bus）开音节，音节开，元音字母在后排，如果后面辅音堵，还有哑音e来开。（hi，he，cake， theme， kite，nose，cute）

  2. 元音字母发音探索1 • A /ei/. 该字母在闭音节发大嘴 ，在开音节发本音 。 闭音节练习：bag, cat, hat, math, traffic, dad, apple, flag, lab, gas, van, Sam, as, fashion 开音节练习：cake, lake, make, take, game, name, same, gate, late, date. 此外，部分a发长音 ，如：father，path，ask，asking，ar组合，park，Mars, far, car, card, party, star, garden, bark

  3. 元音字母发音探索2 • e /i:/. 该字母在闭音节发小嘴 ，在开音节发本音 。 闭音节练习：bed, desk, get, let, net, pet, west, best, zest, seven, eleven, 开音节练习：he, she, we, me, eve, evening, theme,

  4. 元音字母发音探索3 • i /ai/. 该字母在闭音节发 ，在开音节发本音 。 闭音节练习：big, pig, fish, dish, miss, kick, music, comic, traffic, tin, family, milk 开音节练习：like, bike, Mike, bite, hide, kite, Nike, rice, nice, nine, pine, side,

  5. 元音字母发音探索4 • o 该字母在闭音节发 ，在开音节发本音 。 闭音节练习：box, dog, hot, lot, not, blog 开音节练习：nose, coke, rose,

  6. 元音字母发音探索5 • u /ju:/ 该字母在闭音节发 ，在开音节发本音 /ju:/ 。 闭音节练习：bus, cut, duck, luck, must, nut, suck, truck, 开音节练习：use, cute,

  7. 字母组合规律探索1 • ee组合都是发长音/ i: /.如：bee, gee, jeep, keep, meet, need, see, sheep, green等。 • ea组合大部分发长音/ i: /. 如：bean，deal，lead，meat，peak，please，read，sea • ea发 / ei /. great. • ea发/ e /。bread，breakfast

  8. 辅音字母发音规律探索1 • p，b，t，d，k，g，f，v，s，z，m，n基本为所见即所得。 • 轻辅音跟在S后面时，发音要变成对应的浊辅音。但是音标里写出来还是轻辅音。 sport，p看上去还是/p/，读成/b/. skirt, k 看上去还是/k/，读成/g/. school, ch发音是/k/，读成/g/. student，t看上去还是/t/，读成/d/.

  9. 辅音字母发音规律探索2 th有2种发音，分别为/ θ /, / δ /. 相比/s/和/z/的发音，要把舌尖露出来。 Th在单词结尾，多数发轻辅音。如：math, path, fifth, ninth, north, south, month也有特殊的如：with Th在单词中间的，多数发浊辅音。如：father, mother, brother, together, weather, 也有特殊的如：something, nothing, Th在单词开头的，2者都有。 方法：在辨别这类单词时，你可以用2种发音读同一个单词，然后淘汰很别扭的那种发音。

  10. 辅音字母发音规律探索3 m和n的发音也是所见即所得。他们只有一种发音，就是/m/和/n/。在mom和noon中，前后2个发音相同。 这个发音其实就是语文里面的后鼻音。他的写法也是有n+g组合而来。发这个音的字母组合，就是ng。如：hungry，reading，sing，swing等。 nk组合当中，n也发这个后鼻音。如：thank，tank，bank，think，rank等。
