英语的一些发音及初学者问题

英语的一些发音及初学者问题
（1）前缀re-的不同发音
例如：represent [re] review [ri] 为什么在不同单词会有不同发音?
（2）后缀ent的不同发音
例如:student [ənt] represent[ent]
为什么同样是一个单词的组成部分,在不同单词发音会有所不同
（3）音标[ð]的发音问题
例如:the there although 中的th都发这个音,但为什么听起来好像是[d]
（4）一个单词的读音学会音标和发音规则后可以直接拼读,但要知道单词的意思则需要通过查字典.这种说法对吗?
还有,在通过单词读音记忆单词时,例如,ea读[i],可e在某些单词里也读[i],

你可以这么理解、中国汉语有多音字,英语有不同发音~!（好理解了吧~!）
附送给你老师发给我们的资料,你这个问题很难说的,慢慢理解,不懂的地方可以问我.
