英文高手請進:future tense

WILL is something which is expected, though not compulsory. Taking your example, "The council WILL appoint a moderator..."

To make a verb form with "be going to", you first put "be" into the correct form to agree with the subject, and then add "going to" + the simple form of the verb. Note also that "be" is often shortened.

Examples: I am going to leave.

"Be going to" is usually used when something is already planned or definite. Look at the difference between these sentences:
I will make the supper. (Making a decision/volunteering to do something).
I am going to make the supper. (This is already planned and organized.

am/are/is+verb-ing is to indicate something you are doing right now (or at the current moment).
For example: I am doing my homework now.
They are cleaning the house right now.
The bird is eating its food.

will , be going to , am/are/is+verb-ing 三個都是說現在 :
will : 即時決定的事
be going to :
1.
is / am / are + going to
2.
過去已經知道的事
am/are/is+verb-ing : 最 easy , 看到句子裡有現在意C的字時才用

其實講到未來的事，我們可以用
1)be(或其變化形） to + infinitive
2)be(或其變化形) + ing
3)will be + ing
4)be going to
5)will + infinitive
如: 1)I am to visit Taiwan
2)I am visiting Taiwan
3)I will be visiting Taiwan
4)I am going to visit Taiwan
5)I will visit Taiwan

這五句第一句是表示”一早安排好”，而第五句是表示”臨時決定”，而中間的幾句，則其早已安排好的意思依次遞減。所以，做練習時，就要看句子早已安排的意味到哪個層次，才決定用哪種。
最後，若說到鐡定的事實，我們還可用simple present tense，但通常這用法會說明時間，如：
He starts for London tomorrow.
希望幫到你！

will: 加上動辭 = 將要做 (某事) . e.g. I will go to swim tomorrow.
be going to: 肯定將要做 (某事) . e.g. We will be going to school this
afternoon.
am/are/is+verb-ing: 正在做緊 (某事). e.g. I am reading this moment.
You are looking at me.
He is playing piano.
