“I will”和“I am going to”都是代表未來(lái)的動(dòng)作（The Future）.
I WILL：
當(dāng)我們剛決定打算要做一樣?xùn)|西：
Lucy：Have you decided yet?你決定了嗎?
John：Yes,We will go to Penang,It is cheaper.是的,我們會(huì)去檳城,因?yàn)橘M(fèi)用比較便宜.
I AM GOING：
當(dāng)我們較早的時(shí)候已經(jīng)作出決定,而且這是第二次提出來(lái)將要做什么：
當(dāng) John告訴 Lucy他們會(huì)去檳城,第二天John Stanley告訴另外一位朋友.
John：Lucy and I are going to Penang next week.Lucy和我下個(gè)星期去檳城.
Michael：That’s great!那很好!
更多例子作為比較：
I will
例(1) I think it will rain tonight
我看今晚會(huì)下雨.（不肯定）
例(2)A:There is a customer waiting for you.有一位顧客等著你.
B:Okay.I will see him in a few minutes time.我會(huì)在幾分鐘后見(jiàn)他.(B 剛剛接到消息.）
I am going to
例(1)Look!It is going to rain.
你看,快要下雨了!（差不多就發(fā)生了）
例(2)A:There is a customer waiting for you.有一位顧客等著你.
B:I know.I am going to see him in a few minutes time.我知道,我會(huì)在幾分鐘后見(jiàn)他.（B 已經(jīng)知道）
“I will……”是不確定會(huì)做的動(dòng)作,而且這個(gè)未來(lái)詞也是腦里剛決定會(huì)做的動(dòng)作.
“I am going to……”是之前已經(jīng)提過(guò)要做的動(dòng)作,而且即將發(fā)生,而所要發(fā)生的事情是自然而然的,并不是刻意去做.
例如：（你既然覺(jué)得不舒服）I feel funny.I think I am going to have stomache be sick.我覺(jué)得不對(duì)勁,肚子要開(kāi)始痛了.
我們不能夠講.“I feel funny.I will be sick.”（這個(gè)will的用法不正確）
練習(xí)：
填上適當(dāng)?shù)奈磥?lái)動(dòng)詞,“will”或是“is/are/am+going……”
