規則(6)：英文中有所謂的助動詞
必須注意
英文中有很多動詞都是助詞動，在規則(4)中，
我們說在絕大多數的否定語句中，必須用助動詞do 或
did。
Do 是原形動詞，did 和does 都是do 的變形
除了do 是助動詞以外，can、may、might、will、would、
must 也都是助動詞
以上所提到的助動詞，都有一個共同的特色，那就
是這些助動詞後的動詞必須是原形動詞，以下的句子都
是正確的：
He can swim.
He does not swim.
I do not speak English.
You must walk to work every day.
I did not work yesterday.
You may leave now.
I will go to Taipei tomorrow.
以下的句子都是錯的：
* I did not went.
* He does not goes to work.
* You must walked to work.
除了以上的助動詞以外，還有一個非常特殊的助動
詞，那就是have，在這個助動詞的後面，動詞絕對不能
用原形動詞，以下是用這個助動詞的例子：
I have been to England.
I have slept all day.
I have studied English since I was a child.
been、slept 和studied 都是過去分詞(past participle)，
以下的句子也都是現在完成式，我們後討論完成式的時
候，會將這些解釋清楚的
規則(7)：英文問句要有助動詞
我們先看看以下的英文句子，這些都是錯的：
* How many books you wrote
* How many sons you have
正確的句子是：
Why do you drink so much water
How many books did you write
How many sons do you have
絕大多數的英文問句子是一定要有助動詞，以下全
是正確的英文問句，你可以看出每一句的助動詞嗎
Do you love me
Did you go to school yesterday
How many books do you have
How much money does he have
Why don’t you go back home
Do you like to swim
Can you play violin
Will you go home tomorrow
Would you give me a call
當然啦，一旦動詞是verb to be，我們又不需要助動
詞了，以下都是正確的英文問句：
Are you a teacher?
Is he a student?
Is Mr. Chang your father?
Were your mother and father in England last year?
規則(8)：特殊動詞隨主詞的變化
英文中，有些動詞因主詞不同而改變，verb to be 是
其中之一，因此，我們必須記得以下的規則：
現在式
過去式
Verb to have 也有類似的變化：
現在式
過去式
以下的句子都有錯，請將正確的句子寫出來：
1.* I am like my parent.
2.* He is loves his teacher.
3.* He keeps swim every day.
4.* He wants drink a glass of water.
5.* He likes play violin.
