很多正在學習英文的人都不太會用 “Do” 和 “Be” 的用法。 不論是在回答問題或者是問問題都感到困惑。

在思考什麼時要用 Do/Be，以下這些步驟可以令你更加明白什麼時候要用那一項：

一： 認識SVO

什麼是SVO?
Subject主語, Verb動詞, Object受詞

• Subject 可以是noun名詞，pronoun代名詞，gerund動名詞

例子(e.g.)

• Name (Sam, Apple, Couch potato english)
• Pronoun (I, we, they, she, he, it)
• gerund: will be discuss in here (link)

動詞Verb: 動作(eat, drink, think, sing)

Object受詞 : a noun

Jim is a boy.

Jim 是一個男孩。

二： 要清楚了解何時用，我們要關注「動詞」。

2.1 “Be”

上途例子動詞就是以”Be”開始, 形式包括有:

現在式 present tense: is, am, are

過去式 past tense: was, were

當要問問題時，我們會將動詞 “be: is” 放在前面變成：

Is Jim a boy?

Jim 是一名男孩子嗎？

⚠️秘決： 先想一下答題，再想一下問題應該怎樣問。

2.2 “Do”

現在式 present tense: do/does

過去式 past tense: did
Do?

當你的主詞(subject)是這些

1. We, They, You, I
2. Plural 復數

Does？

當你的主詞(subject)是這些

1. He, she, it
2. Singular 單數

Did?

只要是過去式就可以了，不理是否單數或復數。

當你的動詞不再是 “Be”的話，你就要用 Do 去問題。可能會比較抽象，我先舉一個例子：

Jim likes candies.

上途例子動詞用了”Be”以外的動詞： “like”

可是我們不能像”Be” 這麼簡單放在主語前面，所以這個時候便要需要”Do”的幫忙。

由於Jim是單數 —＞ Does

Does Jim like candies？
⚠️秘決： 主動詞會留在原位，並還原最原本的樣子

好！現在先試將下列答句變成問句：

1. Clara loves my deer on the wall.
2. She often draws picture.
3. They forgot to bring the key this morning.
4. He is the president of the U.S..
5. He brushes his teeth today.
6. John and Josh went out yesterday.
7. She is happy.

Answer:

1. Clara loves my deer on the wall —> Does Clara love the deer on the wall?
2. She often draws picture. —> Does she often draw picture?
3. They forgot to bring the key this morning. —> Did they forget to bring the key this morning?
4. He is the president of the U.S.. —> Is he the president of the U.S.?
5. He brushes his teeth today. —> Does he brush his teeth today?
6. John and Josh went out yesterday. —> Did they go out yesterday?
7. She is happy. —> Is she happy?
