這兩句英文的問題和其他問題

一.The reason why I didn’t go to party was not because I forgot it but because I was sick then.
1.為什麼這句要放why 如果沒放 不是沒差嗎？
why是關係副詞，帶出一個形容詞子句當「修飾語」，修飾先行詞reason。可以省去why。

2.was not because 不是因為 為什麼還要放was 前面不是有go to party的動詞了嗎 為何還可以放be動詞？
was是主要子句的動詞，而go只是形容詞子句的動詞。兩者位階不同。
二.the reason I didn't buy the car was because that I thought it was too expensive
為什麼這句也是because 前面可以放be動詞 不是有buy the car動詞了嗎？
這句只能選用because或that，不能同時用兩者，否則語法錯誤。第一個be動詞是主要子句的動詞，buy是形容詞子句的。這句後面還有名詞子句，也有自己的動詞（可看到第二個was）。

三.關係代名詞.形容詞子句是什麼？可以詳細解說嗎？常常會跟that連接子句搞混
形容詞子句又稱「關係子句」，會使用到「關係代名詞」「關係副詞」或「關係形容詞」帶出這個子句。關係代名詞就是代替先行詞的代名詞，在形容詞子句裡當主詞或受詞。that可當「關係代名詞」，帶出「形容詞子句」，也可當「連接詞」，帶出「名詞子句」。

四.可以給我點餐的英文嗎？我是點餐人員 比如今天要點什麼之類的話
What do you like for your breakfast/lunch/dinner?
What do you like to order?
What do you like to eat?
What do you like to drink?

五.動詞加p.p表示被動是什麼意思
應該是助動詞be＋主要動詞的p.p.=被動態

六.在現在完成式中又看到ing是什麼意思 有現在完成進行式？
現在完成式是 have + p.p.
現在完成進行式是 have + been + ~ing
請不要弄混了。

七.可以告訴我be在任何時態要如何用 (be been being)這個
be可當主要動詞，也可以當助動詞
be是原形動詞
been是過去分詞
being是現在分詞
will be（be的未來式，be是原形，因為前面有助動詞）
have/has been（be的現在完成式：助動詞have/has + p.p.）
be通常不用進行式（助動詞be+現在分詞being=現在進行式），但表示一時的行為時可：
You are being too kind to him, aren't you.=你對他太客氣了吧？
