英文文法疑問

1....would host a competition known
as the battle of the bands
呢度既"known as"指的是?

2.That's not the end of the day to them
(對他們來說並不是世界未日)
呢句文法有錯嗎?

3.-In most big cities
-That's the most beautiful lady.

"most"呢個字,究竟幾時在前面先需要加the?

4.neightbors never get around to knowing each other
點解to之後,know會加ing?

5.Besides studying
可否變成"Besides of study"或"Besides study"?


5.-He and I have been very closed ever since he moved in next door to us
Five years ago
如果形容大家一直都係咁close,點解要用現在完成式?

6.I'm sorry for any pain this has caused your family
呢度既"cause"是指什麼
