In this video lesson we'll learn how to ask can I do something in Chinese with 能, and also we'll compare 能 vs. 会 in Chinese.
The Modal Verb 能 néng can be used to suggest (1) possibility to do something (2) rationality to do something.
Like other Modal Verbs, 能 can be used before a Verb Predicate, following such structure,
One thing to notice is that 能 is usually used (1) to ask a question or (2) in a negative sentences
For example,
(1) 能 used to ask a question
With Object
Without Object
(2) 能 used in a negative sentences
With Object
Without Object
To answer 能-question with Yes/No, we don't really simply say néng 能 and bùnéng 不能 for yes and no.
More likely, we use kěyǐ 可以 for yes and bùxíng 不行 for no. For example,
Q: nǐ néng gěiwǒ mǎi běn shū ma
你能给我买本书吗?
can you buy me a book
Y: kěyǐ
可以。
yes; okay
N: bùxíng
不行。
no; (it's) not (gonna) work
Q: wǒ néng kāi diànshì ma
我能开电视吗?
can I turn on the TV
Y: kěyǐ
可以。
yes; okay
N: bùxíng
不行。
no; (it's) not (gonna) work
However, when the answer is no, answering with only 不行 might sound too blunt or impolite. Adding 对不起 and a little explanation can help soften the tone.
For example,
Q: nǐ néng kāi diànshì ma
你能开电视吗?
can you turn on the TV
A: duìbuqǐ, bùxíng, wǒ bù zhīdào kāiguān zài nǎr
对不起,不行,我不知道开关在哪儿。
sorry, no, I don't know where the power button is
Q: wǒmen jīntiān wǎnshàng néng chī pīsà ma
我们今天晚上能吃披萨吗?
can we eat pizza tonight
A: bùxíng, jīntiān shì wǒ māma de shēngrì, tā xiǎng chī jiǎozi
不行,今天是我妈妈的生日,她想吃饺子。
no, today is my mon's birthday; she wants to eat dumplings
We have learned Modal Verb 会 huì before, both 会 and 能 can be translated as "can" or "to be able to" in English. But there are distinct differences between them.
会 suggests one’s ability to do something.
能 suggests (1) the possibility to do something (2) the rationality to do something.
For example,
In Chinese both kāi 开 and guān 关 have two meanings.
And when 开 and 关 are put together, they make a Compound 合成词 Héchéngcí - 开关.
In grammar 2, this sentence 你能给我买本书吗?is missing the word 一 (for 一本书)
