In 我去北京旅行, is 北京 the object? If not, what *is* it?

Question

I am a native speaker who is learning about how Chinese grammar works. I know that a simple sentence contains a subject (主语), a verb (谓语?) and an object (宾语). > 我(subject)吃(verb)饭(object)。 I am also aware that there are other "X语" like 状语, 表语, 补语 etc. I have little to no understanding of how they come into play. I came across this sentence: > 我去北京旅行。 Obviously, 我 is the subject, 去 is the verb. But which is the object? 北京 or 旅行? If either of them is the object, then what is the other one? 补语?

Answer 1

"我去北京旅行。”is a typical sentence with verb constructions in series. We call this type of sentence 连动句．The predicate (谓语) of this type of sentence consists of two or more verbs or verb phases. The basic functions are:

1. Indicating the purpose of an action: go to / come to + (a place) + to do something

Eg,   我去北京学汉语。I go to Beijing to learn Chinese.

      她来美国上大学。She came to the U.S. to go to college.

  Sometimes, the location doesn’t show up and you will see 来/去+V.

   Eg,    我去学汉语。I go to learn Chinese.

                她来上大学。She came here for college.

2. Indicating how to do something/ something is done.

  Eg, 我们坐飞机去上海。We went to shanghai by plane.

         他们用汉语聊天儿。They chat in Chinese.

我经常上网查资料。I often look for information online.

Hope the answer helps you have a better understanding of the grammar point. Thanks.

Answer 2

我去北京旅行。 （主语+ 谓语）

我（名词，subject)去（动词，verb)北京旅行（动补）。
