Tense．．．

1. 怎樣分Simple Present Tense，Simple future Tense，Present continuous Tense？

simple present tense 係用黎講一d日常都會發生既事, 如一d習慣, 嗜好, 常識之類
例如:
He goes to school everyday
The sun rises every morning
It is cold in the winter
She plays tennis very well.

Simple future 就係講d未來野啦,有will, going to, shall 之類, 比較易
will 同 going to就比較肯定, shall就冇咁肯定,有時may,might, could果d都可以做future tense架
例如:
He is going to the bar tonight
I will attend guitar lesson next Monday
Shall we have dinner in the restaurant this weekend?
It might rain tomorrow.

Present Continuous 係現在進行, 即係宜家發生緊既事先用
例如:
I am going to school now.
He is watch television.
She is doing her homework now.
