Question

“in which”等于“where”，“on which”等于“where”吗？

Answer 1

关系副词都等于一个适当的介词＋which，在从句中作状语。

When=in/at/on/…+which.

Where=in/at/on/…+which.

Why=for /…+which.

1、Do you still remember the day when(on which) we went to visit the museum together?

2、This is the factory where(in which)my father once worked.

3、This is the reason why(for which) he was late.

辅音

多数辅音的读音与拼音差别不大，可以通过拼音来进行谐音；还有一部分辅音没有对应的拼音字体，这里我们主要是针对/θ ð ʃ ʒ/这四个辅音。/θ/和/ð/这两个音标，并没有相近似的拼音来对应，主要是靠嘴形来记忆。

/θ/――上下牙齿咬着舌头尖，发“斯"的音；/ð/――舌头顶上牙堂发拼音z一声；/ʃ/――师；/ʒ/――牙齿闭合，舌头虚碰牙齿发拼音r一声。
