Yes, but not merely preceding verb phrases, sometimes it could also be prepositional phrases.

<p>The role of '来' in  [<strong>根据</strong>(...)<strong>来</strong>(...)] is the same as [<strong>base on</strong> (....)<strong>to</strong>(...)] in English.</p>

So since 来 is a preposition here, what is the verb in this sentence?

"分析"  is the *main verb* ; "根据" is the *auxiliary verb*. More example: In  "use money to buy" , "buy" is the *main verb*;  "use" is the *auxiliary verb*.

In  "use money to buy votes",  'money'  is the indirect object; 'votes' is the direct object' . The verb 'use' acts on the indirect object 'money'  is the auxiliary verb; the verb 'buy' acts on the direct object 'votes' is the main verb.

Or is the use of 来 the same as [the one here](https://resources.allsetlearning.com/chinese/grammar/Using_%22lai%22_to_connect_two_verb_phrases)? Then it makes sense, if you treat 要 and 分析 as verbs and 整体 as an adverb.

@Blaszard, yes, [根据... 来] mean [according to...] , (not an auxiliary verb) . It is the preposition of the statement "自己的饮食结构" ( one's own eating habit) to indicate the statement is the source / reason for the following result "整体分析"

Then I don't understand your comment as well. You said in the comment above as follows: `"根据" is the auxiliary verb.`. And does your "yes" point to the `Or is the use of 来 the same as the one here?`?

"to" has a lot of different usage. In (1 .)"use money to buy friend", "**use" is an auxiliary verb**; In (2.) "according to weight to divide classes" , "**according to" is a preposition**.  Both sentences use "to" but  in different structure. (1.) [auxiliary verb+indirect object+to + main verb+ direct object]; (2.) [preposition+relative phrase + to + verb ]

<p>I don't know what language you normally speak.  In German, we have exactly the same usage of ‘来’and '去'. These are the words 'her', pronounced like English 'hair' and 'hin'.

<p>This '来’is 'from'. Not really a contradiction of Tang Ho. If you think of 2 points, A and B, and something moves from A to B, then, depending on whether the observer is standing at A or B, the thing 'moves from 动来' or 'moves to 动去'. This is 'her' or 'hin', '来' or '去'</p>

This is a great question!

来 here is used like **a modal auxiliary** in English, to express what one's intention/or going to do with/according to/about/... aforementioned stuff.

For example, 我们要用自己的双手来建设祖国。 （We will build our country with our own hands）. Here what our intention or going to do is 建设祖国（build our country）, with aforementioned stuff 要用自己的双手.

For the case OP quoted, 要根据自己的饮食结构来整体分析, what our intention or going to do is 整体分析 according to 自己的饮食结构.

"来" here functions as the preposition "to"

> [to](https://www.merriam-webster.com/dictionary/to):
>
> *2--(a)used as a function word to indicate purpose, intention, tendency, result, or end*
>
> *2--(b) used as a function word to indicate the result of an action or a process*
>
> The intention of '根据自己的饮食结构' is to '整体分析'

The role of '来' in [**根据**(...)**来**(...)] is the same as [**base on** (....)**to**(...)] in English.

Example:

[**根据**(体重)**来**(分级)] = [**base on** (weight) **to** (divide classes)]

[**以**(数目大小)**来**(定胜负)] = [**according to** (size of of the number) **to** (decide winner and loser)]

[**用**(重武器)**来**(攻击)] = [**use** (heavy weapon) **to** (attack)

> In all the examples above, the preposition '来' can be omitted in Chinese
