Formal:
* 请问您会说英语吗? (Qǐngwèn nín huì shuō Yīngyǔ ma?) - "Excuse me, do you speak English?" This is a polite and formal way to ask.
* 请问您能用英语交流吗? (Qǐngwèn nín néng yòng Yīngyǔ jiāoliú ma?) - "Excuse me, can you communicate in English?" This is also very polite and suitable for formal situations.
Informal:
* 你会说英语吗? (Nǐ huì shuō Yīngyǔ ma?) - "Do you speak English?" This is a more casual way to ask.
* 你英文好吗? (Nǐ Yīngwén hǎo ma?) - "Is your English good?" This is even more casual and might be used with friends or family.
To get someone's attention before asking:
* 打扰一下 (Dǎrǎo yīxià) - "Excuse me" or "Pardon me"
* 不好意思 (Bù hǎoyìsi) - "Excuse me" or "Sorry to bother you"
You can combine any of these phrases with "我需要用英语交流 (wǒ xūyào yòng Yīngyǔ jiāoliú) - I need to communicate in English" for a complete sentence.
For example:
* 打扰一下,请问您会说英语吗? (Dǎrǎo yīxià, qǐngwèn nín huì shuō Yīngyǔ ma?) - "Excuse me, do you speak English?"
* 不好意思,你会说英语吗?我需要用英语交流。 (Bù hǎoyìsi, nǐ huì shuō Yīngyǔ ma? Wǒ xūyào yòng Yīngyǔ jiāoliú.) - "Excuse me, do you speak English? I need to communicate in English."
Remember to be polite and patient when asking.
