What is the infinitive mantra in English?

If you want to learn English well, the verb infinitive is infinitive.

The usage formula must not be liquid, and the following is the formula:

1.From time to time there is a mark, and the to is joined with the verb.

The mantra about the usage of the infinitive is as follows:

It can be connected to both the infinitive and the verb-ing form, but the verb or phrase with different meanings: that is, four "remember", "strive" and "do not regret". Fourth, "remember" means "remember", "forget", "plan, mean", "roll or"; "go on"; Strive to refer to "try"; "No" and "regret" refer to stop and regret.

The usage formula of to, to can be either a preposition or a structural particle. When used as a preposition, it is followed by a noun or gerund, e.g., give the book to am looking forward to seeing you

As for when to use, the usage of prepositions is all fixed collocation, and instead of memorizing multiple meanings that are easily confused, it is better to memorize fixed phrases directly. Da Xun Wu.

When the sitting structure particle is used, it is an infinitive, that is, the to do form, which must be followed by the verb form. It can also be understood as a fixed collocation, such as want to do, be going to do. So it's best to remember fixed phrases as well.

After the modal verb, the v is added directly without to. Add to do sth(Such as:.)

1. The difference between a gerund (doing) and an infinitive (to do) when it is used as a subject or predicate.

There is a general difference between the gerund (doing) and the infinitive (to do) in the expression of meaning when being the subject and predicate: the gerund (doing) often expresses an abstract action without a hint of time, while the infinitive (to do) often indicates a specific action that has not occurred.

2. The difference between a gerund (doing) and an infinitive (to do) when making a definite.

The gerund (doing) is a class of non-predicate verbs that are not particularly widely used, often indicating a function of the modified noun, placed before the modified word, and does not form a logical relationship (subject-verb or verb-object) with the modified word. e.g. reading room; Swmming Pool.

The infinitive (to do) is a very widely used form of definite, which is placed after the defect of the modified word and forms a logical relationship (subject-verb or verb-object) with the modified word.

3. The difference between a gerund (doing) and an infinitive (to do) when it is used as a complement.

In terms of the function of complements, gerunds (doing) and infinitives (to do) are often produced according to the habit of use.
