男主姓冷和女主角姓苏:英语问题

1、there／here前加in表示在......内部
如：It's hot here. 可能表示这个地方热
It's hot in here. 表示房间（...)内热

2、st组合：完全可以按照[st]发音，只要读得快一点就会发现有时会失去爆破成了类似[sd]的音，有时并不变化，所以并不是有什么规律，而是自然变化。
试一下这些词：
stop stairs 这些会变化

yesterday most 不会变化

可以肯定的是，如果s、t不属于同一个音节（如yes-ter-day),读音不会变化；
也可以肯定，如果音节以st结尾，也不会变化；
至于什么时候会变化，可以不去管它，尽管按照〔st]去读，读快一点，自然就来了，如student，你想读成t也难。

最后，清辅音[t]并不是真的成了浊辅音[d]，只是失去爆破而已，就好像法语的爆破音一样。

这时肯定是发/t/

1.习惯问题
2.读"yesterday"."most"时,s后面的t不要读成/d/
规律:单音节词,s为收发读音时,其后面的辅音要变化,如store sky strong ====
多音节词,s为每音节收发读音时,其后面的辅音要变化,如struggle understand upstair ====

just sounds like 'd', but not. Maybe sb has a particular accent.

in there, it's in there... i think it's should have in here, because there is a noun in this condition.
about the pronouciation, i think it deponds on the accent, you can have either /T/ or /D/ sound. But when you pronouce it as /d/, just make sure don't pronouce it too strong. It's just a little bit /d/ sound, somewhere between the triditional chinese way of saying /t/ and /d/...
