英语的连读怎么区分啊?最近,老师帮我们练听力,可连读总是错,连读怎样区分啊?求高人指教!

连读的条件：相邻的两词在意义上必须密切相关,同属一个意群.连读所构成的音节一般都不重读,只需顺其自然地一带而过,不可读得太重,也不可音.(连读符号：~) (1)“辅音+元音”型连读在同一个意群里,如果相邻两词中的前一个词是以辅音结尾,后一个词是以元音开头,这就要将辅音与元音拼起来连读. I’m~an~English boy. It~is~an~old book. Let me have~a look~at~it. Ms Black worked in~an~office last~yesterday. I called~you half~an~hour~ago. Put~it~on, please. Not~at~all. Please pick~it~up. (2)“r/re+元音”型连读如果前一个词是以-r或者-re结尾,后一个词是以元音开头,这时的r或re不但要发/r/,而且还要与后面的元音拼起来连读. They’re my father~and mother. I looked for~it here~and there. There~is a football under~it. There~are some books on the desk. Here~is a letter for you. Here~are four~eggs. But where~is my cup? Where~are your brother~and sister? 但是,如果一个音节的前后都有字母r,即使后面的词以元音开头,也不能连读. The black clouds are coming nearer and nearer.（nearer与and不可连读） (3)“辅音+半元音”型连读英语语音中的/j/和/w/是半元音,如果前一个词是以辅音结尾,后一个词是以半元音,特别是/j/开头,此时也要连读. Thank~you. Nice to meet~you. Did~you get there late~again? Would~you like~a cup~of tea? Could~you help me, please? “音的同化”—常把/d/+/j/读成/dV/,did you听上成了/dIdVu/,would you成了/wudVu/,could you成了/kudVu/. (4)“元音+元音”型连读如果前一个词以元音结尾,后一个词以元音开头,这两个音往往也要自然而不间断地连读到一起. I~am Chinese. He~is very friendly to me. She wants to study~English. How~and why did you come here? She can’t carry~it. It’ll take you three~hours to walk there. The question is too~easy for him to answer. (5)当短语或从句之间按意群进行停顿时,意群与意群之间即使有两个相邻的辅音与元音出现,也不可连读.Is~it a~hat or a cat?（hat与or之间不可以连读）There~is~a good book in my desk. （book与in之间不可以连读）Can you speak~English or French? （English与or之间不可以连读） Shall we meet at~eight or ten tomorrow morning? （meet与 at,eight与or之间不可以连读）She opened the door and walked~in. （door与and之间不可以连读）失去爆破6个爆破音有3对/p/,/b/,/t/,/d/,/k/,/g/失去爆破,又叫不完全爆破,就是在某些情况下,只须做出发音的准备,但并不发音,稍稍停顿后就发后面的音.(1)“爆破音+爆破音”型6个爆破音中的任意2个相临时,前一个爆破音会失去爆破,即由相关的发音器官做好这个发音的姿势,稍做停顿后即发后面的爆破音.
