Hello Peng! Well done! Kaz is right, and so are you – it's my sisters and my father live in London. It's important in English that the subject of a sentence agrees with the verb. So in the simple present tense, when the subject is singular, we add –s to the verb, like this: My father lives in Beijing. With the verb 'to be' we say: Chinese food is delicious And an –ing subject is also single: Living in London costs a lot of money Now when the subject is plural, or if the verb has more than one subject, the verb changes: My sisters live in Beijing. My mother and my father live in London. But, if we use each or every, the verb remains singular. Listen: Every resident has to pay tax. Each address is listed in a special register. Finally, the subject and verb must agree with each other, even if they get separated by extra information like this: Her parents, despite retiring several years ago, still live in the city. So to sum up: singular subjects take singular verbs, but plural or multiple subjects take plural verbs, even when they are separated from their subjects. Subjects with each and every usually take a singular verb. Ok, that's all from me. Good luck with your grammar challenge! ...
