因為蠻多人都會弄不清楚什麼時候用 do does 造問句，什麼時候用 am is are 造問句。做成影片，希望有解釋的比較清楚，後面也有過去式，規則是一樣的，可以看完影片或文字解釋後，自己做練習題，全部做完再對答案，看自己懂了沒。有其他問題可以參考潔西家的文法連結整理，也可以留言問潔西。
簡言之：
英文的句子，每個句子都要有一個主詞跟一個動詞。要把句子改成否定句或疑問句時都需要助動詞來幫忙。怎麼樣找適當的助動詞呢？
第一：先辨別句子的時態，找出句子的動詞，現在簡單式的句子有兩種句型，可能是用一般動詞 1. He comes from Taipei. 或be動詞 2. He is from Taipei. 現在進行式的句型 3. He is working. 這三個句子的動詞分別是 comes, is, is working。
第二：當句子本身有助動詞時，直接在助動詞後面加not造否定句，把助動詞放到主詞前面造問句，因為be動詞本身就是助動詞，所以改問句時2跟3句就直接改成 2. Is he from Taipei? 3. Is he working?
第三：當句子本身沒有助動詞時，必須要依照時態與主詞的不同找一個助動詞來幫忙，在助動詞後面加not改否定，把助動詞放到主詞前面早問句。現在簡單式的助動詞是do/does，第三人稱單數時用does。所以第一句的疑問句就會是 Does he come from Taipei?

現在式助動詞do/does與am/is/are 造問句時的用法與區別
英文造問句與改否定的時候都需要一個助動詞，這個助動詞依主詞，表達的時態，表達的語態會有所不同。造問句的時候要把助動詞放到主詞前面，造否定把 not 放到助動詞後面。要決定助動詞先要先弄清楚要表達的是哪個時態，來選擇助動詞，在依主詞不同，選擇最適當的助動詞。
Do you drink coffee every morning?
Are you drink coffee every morning? (X)
Are you busy?
Do you busy? (X)
A 現在簡單式：
表達事實或一般習慣狀態時，因為有兩種不同句型，按不同句型用不同的助動詞。
一般動詞句型：助動詞為 do/does ，第三人稱單數用 does ，其他用 do 造問句。
be動詞句型：am/is/are 為動詞也是助動詞，按不同的主詞用 am/is/are 造問句。
形式/句型：主詞＋動詞原型(第三人稱單數動詞加 s) S +V1

B 現在進行式：
表達現在正在進行的動作，短暫性的動作時，本身句型有 am/is/are 三個助動詞，而且動詞會加 ing。造問句時用 am/is/are 造問句，依主詞不同，來決定助動詞是 am, is, 還是 are。

缺助動詞的句子可以看句子有沒有一般動詞，有一般動詞的原型的話，就是現在簡單式，用 do/does 造問句。有一般動詞的現在分詞(動詞ing/V-ing)時，就是現在進行式用am/is/are 造問句。假如完全沒有動詞，就需要 am/is/are 當動詞，就用 am/is/are 造問句。

10 __Is she ___________ working overtime now?
還是不清楚的可以看下面的影片或下面更詳細的每個時態的句型，會比較有清楚的概念
最前面簡單說明一下：
現在簡單式最簡單的辨識方式是看句子裡面有沒有 be 動詞，有 be 動詞的話就用 am, is, are 造問句
I am late. — Am I late?
He is busy. — Is he busy?
They are at home. — Are they at home?
.
現在簡單式的句子裡面沒有 be 動詞時，一定就是一般動詞的句子，就需要用 do, does 造問句
They walk home. — Do they walk home?
He plays basketball every day. — Does he play basketball every day?
.
現在進行式的句型就是 be + V-ing ，所以一定有 be 動詞，就用 be 造問句。
I am dreaming. — Am I dreaming?
She is cooking. — Is she cooking?
They are swimming. — Are they swimming?
.
Do/Does/Am/Is/Are/Did/Was/Were 用法大解說
A 助動詞DO/DOES與AM/IS/ARE 造問句時的用法與區別
He is at work. 現在簡單式
He works from 9 to 5. 現在簡單式
He is working. 現在進行式
英文造問句與改否定的時候都需要一個助動詞，這個助動詞依主詞，表達的時態，表達的語態會有所不同。造問句的時候要把助動詞放到主詞前面，造否定把 not 放到助動詞後面。 要決定用 do/does 還是 am/is/are 造問句，首先要看句子本身有沒有一般動詞，如果有一般動詞就用 do/does，沒有的話就用 am/is/are。再來看人稱，再決定用的是 do 或 does，是 am, is, 還是are。
1 現在簡單式
用來表達經常性的動作，習慣跟事實。句型可分兩種，有一般動詞的句子，跟 be 動詞的句子。句子裡有一般動詞的時候，用 do 或 does 造問句。句子裡沒有一般動詞，而是 be 動詞 am, is, are 的時候，就用 am, is, are 來造問句。
這邊要特別注意的是學英文的時候記單字要記得連單字的詞性一起記。這樣才能分辨句子中有沒有動詞，才知道要要用哪個助動詞造問句。比方說中文的我很忙。我很累。忙跟累感覺都是動詞。但是在英文常用的單字是 busy , tired 這兩個字都是形容詞，所以問你忙嗎？會是 Are you busy? 而不會是 Do you busy?(X) 這個錯誤的句子。問你喝咖啡嗎？因為喝 drink 是動詞，所以會是 Do you drink coffee? 而不會是 Are you drink coffee?(X) 這個錯誤的句子。
a 一般動詞的句型：
有一般動詞的句子，肯定句是用主詞加動詞原型，但是第三人稱單數 he, she, it 或者任何可以用這三個代名詞代替的名詞，比方說 my father = he, his girlfriend = she, the dog = it ，這些第三人稱單數名詞後面的動詞要加 s 或 es，比方說 works, watches。在改否定的時候第三人稱單數用 does + not = doesn’t ，不是第三人稱單數的名詞就用 do + not = don’t 。造問句時把 do 跟 does 放到主詞的前面，在助動詞 do, does 的後面加的動詞都是動詞原型。
肯定句：主詞＋動詞原型 (第三人稱單數加s)
S + V1
I work.
You work.
We work.
They work.
He works.
She works.
It works.
.
否定句：主詞＋助動詞 do/does＋not ＋動詞原型 (第三人稱單數用 does)
S + do/does + not + V1
I do not work.
You do not work.
We do not work.
They do not work.
He does not work.
She does not work.
It does not work.
.
Yes/No 問句： Do/Does + 主詞＋動詞原型？
Do/Does + S + V1
Do I work?
Do you work?
Do we work?
Do they work?
Does he work?
Does she work?
Does it work?
.
WH 問句： WH + do/does + 主詞＋動詞原型？
WH + do/does + S + V1?
Where do I work?
Where do you work?
Where do we work?
Where does he work?
Where does she work?
Where does it work?
PS: 因為想要讓大家清楚的看到每個助動詞，所以連 I 都放進問句，句子有點怪，我在哪裡工作？通常不會這樣問，不過為了容易懂所以就直接這用造問句。下面的一些例句也是一樣，都是為了統一巨型，所以有些語意會有點怪，請見諒。
.
b BE動詞的句型
BE動詞的句型，就是簡單式的句子中沒有一般動詞，只有名詞，有形容詞，介系詞片語時，會有 be 動詞來當句子的動詞。主詞是 I 時 be動詞為 am，主詞是 you, we, they 或任何可以用這個字代替的代名詞如 my friends and I=we, Tom and Mary = they 用的be動詞是 are ，主詞是 he, she, it 或任何可以用這三個字代替的如 Tom = he, Mary = she, my job = it 時用的 be 動詞是 is。改否定句的時候在 am, is, are 後面加 not 就可以了。改疑問句的時候把 am, is, are 放到主詞前面造問句就可以了。
肯定句 ：主詞＋ am/is/are ＋名詞/形容詞/介系詞片語
S + am/is/are + noun/adjective/preposition phrase
I am a teacher.
You are happy.
We are happy.
They are happy.
He is at home.
She is at home.
It is at home.
.
否定句：主詞＋ am/is/are ＋not + 名詞/形容詞/介系詞片語
S + am/is/are + not + noun/adjective/preposition phrase
I am not a teacher.
You are not happy.
We are not happy.
They are not happy.
He is not at home.
She is not at home.
It is not at home.
.
Yes/No 問句： Am/Is/Are ＋主詞＋ + 名詞/形容詞/介系詞片語?
Am/Is/Are + S + noun/adjective/preposition phrase?
Am I a teacher?
Are you happy?
Are we happy?
Are they happy?
Is he at home?
Is she at home?
Is it at home?
.
WH 問句： WH + am/is/are ＋主詞＋ ?
WH + am/is/are + S + ?
What am I ?
Where are you?
Where are we?
Where are they?
How is he?
How is she?
How is it?
.
2 現在進行式
現在進行式用來表示現在正在進行的動作，短期間發生的動作，或表示未來安排好的事件。句型是主詞加上 be 動詞再加上現在分詞。因為句子本身就有 be 動詞 am, is, are，所以造否定句的時候就在 be 動詞後面加 not，改問句時就把 be 動詞放到主詞前面就可以。
.
肯定句：主詞 ＋ am/is/are ＋現在分詞
S + am/is/are + V-ing
I am cooking.
You are singing.
We are singing.
They are singing.
He is sleeping.
She is sleeping.
It is sleeping.
.
否定句：主詞 ＋ am/is/are ＋ not + 現在分詞
S + am/is/are + not + V-ing
I am not cooking.
You are not singing.
We are not singing.
They are not singing.
He is not sleeping.
She is not sleeping.
It is not sleeping.
.
Yes/No 問句：Am/Is/Are + 主詞 ＋現在分詞？
Am/Is/Are + S + V-ing?
Am I cooking?
Are you singing?
Are we singing?
Are they singing?
Is he sleeping?
Is she sleeping?
Is it sleeping?
.
WH問句 + am/is/are + 主詞 ＋現在分詞？
WH + am/is/are + S + V-ing?
What am I doing?
Where are you going?
Where are we going?
Where are they going?
How is he doing?
How is she doing?
How is it doing?
.
B 過去式也是如此推斷，過去簡單一般動詞的句子就用 did 造問句跟否定，有 be 動詞時就用 was/were 造問句跟否定。過去進行式用 was/were 造問句跟否定。 總之呢，每個時態造問句跟否定都需要用助動詞來幫忙，所以要造問句時，首先要找出句子的助動詞，只有現在簡單或過去簡單會有本身沒有助動詞只有一般動詞的句子，這時候用 do, does, did 造問句，而其他時態，比方說現在完成式用 have/has 造問句。過去完成式用 had 造問句。未來式用 am/is/are 或 will 造問句。不同語態就用不同的助動詞如:would, could, can, may, …等來造問句
如何用正確的助動詞 am/is/are或do/does 造問句
a
可以先看句子裡面有沒有一般動詞，比方說第三句，有 use 這個一般動詞，再看主詞，主詞為 you，所以用 do 造問句：Do you use a computer every day? 假如像第四句，有一般動詞smoke，主詞是第三人稱單數 your brother，則用 does 造問句。Does your brother smoke?
b
句子裡面假如沒有一般動詞，但是有形容詞 lazy, hardworking，或者是名詞 a noisy city 等其他詞性，這時候，看主詞不同，用am, is are造問句。you 的 be 動詞是 are，所以第一句是 Are you lazy or hardworking? 第二句主詞 Taipei 就相當於 it，所以 be 動詞用 is，問句為 Is Taipei a noisy city?
c
句子裡面假如有一般動詞，但是後面是加了 ing 的現在分詞，那麼表示是現在進行式，所以要用 be 動詞造問句。如第五句，有現在分詞 living，這時候要用 be 動詞造問句，主詞是 your father，所以相當於 he，用 is 造問句。Is your father living abroad?
d
假如不知道詞性的話，最好的方式是查字典，因為像 tired 累, busy 忙，這種中文感覺像動詞的字在英文其實都是形容詞喔。
e. 最後切記切記，be 動詞 am/is/are本身就是動詞，所以不會跟一般動詞的原形同時出現，絕對不要把他們放在一起啊:)

B 過句簡單式造問句 did 或 was were
Past Tense was/were/did 的用法
英文的句子一定要有主詞跟動詞。
過去簡單式的句型如下
一般動詞 ： S + V2
I got up early this morning.
沒有一般動詞( be 動詞) ： S + was/were + 名詞/形容詞/介系詞片語
He was worried.
.
1 肯定句：有一般動詞時用動詞的過去式V2
I came to class late.
沒有一般動詞的句子，要有Be2 (was, were)
I was late for class.
.
2 疑問句：有一般動詞用did造問句，動詞改為原型。
Did you come to class late?
沒有一般動詞時，則用 Be2(was, were)造問句。
Were you late for class?
.
過去進行式
1 肯定句：S + was/were + V-ing
She was taking a shower when I called.
2 疑問句：Was/Were + S + V-ing?
Were you taking a shower when I called？
Was she taking a shower when I called?
I/he/she/it was + V-ing, You/We/They were + V-ing.
.
這是個練習的活動，要找到有做這件事的人可以用yes/no問題來問。所以把下面的句子都改成 yes/no 問題，有一般動詞就用 did 造問句，沒有一般動詞，句子就會有 was/were，就用 was/were 造問句。改問句時主詞通通改為 you
比方說
這個句子中有動詞的過去式，所以要用 did 造問句，後面動詞就要變回原型
drank coffee this morning.
Did you drink coffee this morning?
.
下面這個句子裡面有 be 動詞的過去式，因為主詞是 you 所以就用 were 來造問句
was sick last week.
Were you sick last week?
改問句時主詞通通改為 you

do you like to playing piano,
為什麼有ing卻用do?
句子是錯的 Do you like playing the piano? 動詞是 like ，不是 playing
看來我不孤單，原來很多人都搞不懂，哈哈~ 謝謝老師的說明
