Will（I'll） (A1)
说话当下想帮忙时，用 I'll + 动词原形。（I'll = I will。）
I'll help（提议）
- That bag is heavy. I'll carry it.
- I'll help you.
- I'll open the door.
- 试一试: That bag is heavy. ___ carry it. (I'll / I'll to / I carrying) 答案: I'll — 你当场提议要帮忙，所以用 I'll + 动词原形：I'll carry it。不加 to，也不加 -ing。
I'll have tea（当场决定）
说话这一刻才做的决定（不是事先想好的），用 I'll + 动词原形。
- I'm thirsty. I'll have some water.
- Okay, I'll take the bus.
- I'll call you later.
- Not "I'm thirsty. I have some water." — say "I'm thirsty. I'll have some water.". 你是当场决定的，所以用 I'll + 动词原形。
- 试一试: I'm thirsty. ___ have some water. (I'll / I'll to / I having) 答案: I'll — 你是当场决定的，所以用 I'll + 动词原形：I'll have some water。
It'll rain（预测）
表示你觉得会发生什么事，用 'll + 动词原形。（it'll = it will；they'll = they will。）
- Look at the sky. It'll rain.
- Don't worry. It'll be fine.
- They'll be happy.
- 试一试: Look at the sky. ___ rain. (It'll / It rains / It rain) 答案: It'll — 表示你觉得会发生什么事，用 'll：It'll rain。"It rains" 和 "It rain" 说的是日常现在的事，不是对以后的预测。
人人都一样（不加 -s）
Will（'ll）永远不变。he、she、it 也一样用：he'll、she'll、it'll、they'll，永远不加 -s。
- I'll come.
- She'll come.
- They'll come.
- Not "She wills come." — say "She'll come.". 就算是 she，也还是 will（'ll），永远不是 wills。
- 试一试: Don't worry, Hiroshi ___ help you. (he'll / he wills / he'll to) 答案: he'll — Will 永远不加 -s：用 he'll（= he will），不是 "he wills"。而且 will 和动词之间不加任何词，所以不加 "to"。
动词保持原形
will（'ll）后面动词保持原形，不加 -s，不加 -ing。
- He'll come at six.
- She'll help you.
- It'll rain later.
- Not "It will rains." — say "It will rain.". will 后面用动词原形：rain，不是 rains。
- 试一试: He ___ at six. ('ll come / 'll comes / 'll coming) 答案: 'll come — 'll 后面动词保持原形：come。不是 "comes"，也不是 "coming"。
will 后面不加 'to'
will 后面别加 to。说 I'll help，不是 "I'll to help"。
- I'll help you.
- She'll call later.
- We'll wait here.
- 试一试: Don't worry. ___ help you. (I'll / I'll to / I will to) 答案: I'll — will 后面没有 to：I'll help you。"I'll to" 和 "I will to" 都是错的。

要表示否定，用 won't + 动词原形。（won't = will not。）
- Don't worry. I won't be late.
- She won't come today.
- They won't forget.
- Not "I don't be late." — say "I won't be late.". 说以后不会做的事，用 won't，不是 don't。
