The "shi... de" construction for emphasizing details

Also known as: 是⋯⋯的结构 (shì... de jiégòu), 是... 的 sentence and 是... 的 pattern.

The 是……的 (shì... de) construction is used to draw particular attention to certain information in a sentence. It's often used to ask questions that seek specific information, or to explain a situation by emphasizing a particular detail.

While not strictly tied to any "tense," the 是... 的 construction is frequently used when asking details about the past or telling details about the past.

Basic 是... 的 structure

A 是... 的 sentence is formed with this structure:

Subject + 是 + information to be emphasized + Verb + 的

This structure can be used to emphasize any detail, but most commonly it emphasizes time, manner, or place. Don't worry if this still seems a little confusing; lots of helpful examples are coming up!

Simple Question Examples

These are some of the most common questions asked using the 是... 的 construction and some possible answers:

• 你 是 怎么 来 的 ？ Emphasizing "how" or "in what manner"How did you come?
• 你 是 怎么 做 的 ？ Emphasizing "how" or "in what manner"How did you do it?
• 是 谁 告诉 你 的 ？ Emphasizing "who"Who was it that told you?
• 你 是 什么时候 来 的 ？ Emphasizing "when"When did you come?

You might be wondering, "can I still say the same thing without the 是 and the 的?" The answer is that in most cases, no, not really. While the 是 can sometimes be dropped, these examples sound weird without the 的. It's just a part of learning to ask questions naturally in Mandarin. You don't have to learn a "past tense," but you do have to learn this way of asking for details about the past, sooner or later.

Other Examples

Some examples where time is emphasized:

• 我们 是 昨天 来 的。 "Yesterday" is emphasized.)We came yesterday.
• 他 是 去年 到 北京 去 的。 "Last year is emphasized.)He went to Beijing last year.

Some examples where manner is emphasized:

• 她 是 坐 飞机 去 美国 的。 "By plane" is emphasized.)She went to America by plane.
• 我 是 从 香港 转机 到 上海 的。 "from Hong Kong" is emphasized"I'm coming to Shanghai from Hong Kong.

Some examples where place is emphasized:

• 我 是 在 英国 学 英文 的。 "In Britain" is emphasized.)I studied English in Britain.
• 你 是 在 中国 出生 的。 "In China" is emphasized.)You were born in China.

Singling out details for emphasis with 是... 的

As mentioned above, a 是... 的 construction can pick out any detail in a sentence. Whatever comes immediately after 是 is emphasized. So in the sentence below:

• 我 上 周六 跟 我 家人 在 饭馆 吃饭。I ate with my family in a restaurant last Saturday.

We can pick out any one of the details by putting 是 in front of it:

• 我 跟 我家人是 上 周六 在 饭馆 吃 的 饭。"last Saturday" is emphasized.)
• 我 上 周六 在饭馆 是 跟 我 家人 吃 的 饭。"with my family" is emphasized.)
• 我 上 周六 跟 我 家人 是 在 饭馆 吃 的 饭。"in a restaurant" is emphasized.)

When to use 是... 的

As described above, the 是... 的 construction is used to draw attention to particular information in a sentence. Whereas a sentence without a 是... 的 construction might describe a situation, a sentence with a 是... 的 construction explains it. 是... 的 is not generally used for reporting new information, but for adding important details that make the information clearer.

You could think of 是... 的 as being equivalent to saying one of the following in English:

• "The situation is that"
• "It's that ..."
• "It was ... that ..."

If the sentence could be formed with one of those phrases in English, it can probably use a 是... 的 construction in Chinese. Usually the topic of a 是... 的 sentence has already been established.

Completed action

It's important to note that a 是... 的 construction also indicates that an action has been completed. However, this is not the purpose of a 是... 的 construction. The association with a completed action is more like a side effect of 是... 的. This means you shouldn't use 是... 的 just to indicate that an action is completed. Use the aspect particle 了 for that. Instead, use 是... 的 to draw attention to particular features of the action.

Negating 是... 的

是... 的 sentences can only be negated with 不, as 没 can not be used to negate 是. Place 不 before 是 as you would in a standard sentence.

Some examples:

• 我们 不 是 坐 火车 来 的。We didn't come by train.
• 这个 电话 不 是 打给他的。This phone call isn't to him.
• 我们 不 是 去 看她 的。We didn't go to see her.

Note that negating a 是... 的 construction creates the implication that the action in the sentence was carried out, and only the detail emphasized by 是... 的 is being denied. So, in the last sentence, the implication is that 你 didn't go out with 她, but did go out with someone. So negative 是... 的 constructions would work nicely in the final scenes of detective dramas.

是... 的 and questions

是... 的 constructions can be made into questions in the usual three ways to form questions in Chinese:

• With a question particle
• With a question word
• Within affirmative-negative questions

Some examples:

• 你 是 用 手枪 杀害 他 的 吗？Did you use a pistol to murder him?
• 他 是 坐 飞机 去 意大利 的 吗？Did you take a plane to Italy?

• 你 是 跟 谁 出去 的？Who did you go out with?
• 你 是 怎么 来 北京 的？How did you come to Beijing?

• 你们 是 不是 去年 认识 的？Did you meet each other last year?
• 你的 车 是 不是 你弟弟 开 走 的？Was your car driven away by your brother?

是 is often optional

Although this structure is called the 是... 的 construction, the 是 is nearly always optional. You will often hear this structure with 是 omitted, so be aware. The only time 是 is required in this construction is when it's being negated. Other than that, 是 is commonly omitted.

Some examples:

• 他 （是） 昨天 来 的。He came yesterday.
• 我们 （是） 两 个 月 以前 认识 的。We met two months ago.
• 我 （是） 用 中文 问路 的。I used Chinese to ask the way.

Where to put 的 in a 是... 的 construction

Up till now we've said that 的 appears at the end of the sentence in a 是... 的 construction. This is very often the case. However, if there's an object, 的 can appear before the object.

For example:

• 我 是 在 加拿大 学 的 英语。the 的 comes before the object 英语)I studied English in Canada.
• 我 是 在 加拿大 学 英语 的。the 的 comes after the object 英语)I studied English in Canada.

Note that if the object is a person, 的 has to go at the end of the sentence. Otherwise it can go before the object or at the end of the sentence.

• 我 是 在 法国 认识 的 她。the 的 cannot come before the object 她)I met her in France.
• 我 是 在 法国 认识 她 的。the 的 can only come after the object 她)I met her in France.
