The difference between as and like

1. In the role, ability or function of.

Example: Acting as a mediator.

2. In a similar way; Like (in a similar way; Same)

They are of the same mind on this issue. They are in agreement on this issue.

Like a preposition:

Like, like, like.

Usually after someone. Or something. Or gerund (that is, doing something).

Example:

Cann't get away, unlike you You don't look like a temper tantrum.

Live like royalty, live like an emperor.

It feels like I want to escape. . . . . . )

In short, the difference is that as is "as", that is, the fact is that like is "like", but it is not. For example, that person was originally a mediator, so he used as; That man is not an emperor, but he lives like one. That man was going to lose his temper, but people thought he wouldn't lose his temper, so he used like. ...

In the early days, like was an adjective, meaning similar, identical and similar. As is a conjunction.

Sammy is a lot like Sammy. Sammy and Sammy look alike.

Paul acts like a child. Paul behaves like a child. (Sentence omitted)

Later, like was used as a preposition, meaning like ...; As can also be used as a preposition

Paul acts like a child. Paul acts like a child. (The sentence is not omitted)

Compare again:

Let me talk to you as a father ... let me tell you as a father. I am your father, and I am talking to you as a father.

Let me talk to you like a father .. Let me tell you something like your father. I am not your father, but I am talking to you in your father's way.

Later, some grammarians changed the previous rule that "like" was not allowed to be used as a conjunction and used it instead of "as" in adverbial clauses.

I can't sing like before .. I can't sing like before. (of the timbre of singing)

He writes as his brother did when he was young. His writing style is the same as that of his brother when he was young. (Calligraphy Style and Font)

Even so, like and as are sometimes different. Try to compare:

The priest became like a murderer. The prisoner was hanged like a murderer.

The prisoner was turned into a murderer. The prisoner was hanged as a murderer. The prisoner is a murderer.

As and like are both translated as "Xiang" in Chinese, but their literal meanings are different.

Like focuses on the comparison between a and b, which does not mean that a and b belong to the same category or are completely similar.

He speaks English like an Englishman. In a sense, he is an Englishman.

Speak English. )

Show some similarities

As focuses on identity, that is, A and B belong to the same category or are completely similar.

He speaks English like an Englishman. He is also an Englishman. )

Speak just as well.

As and like are two common words in English, which have many meanings and usages. Semantically, these two words can be regarded as "like …" and "just like …", which show the similarity between people, things and things, actions and actions, and states. But its grammatical structure is different.

First, when you say "Xiang", the grammatical structure is different:

1 and as are used as conjunction. She leads the comparison between adverbial clauses and modal adverbial clauses, which are usually ellipsis. For example:

She is an excellent singer, just like her mother used to be.

There is as much water in this cup as in that one.

2. like as a preposition. For example:

My sister is not much like me.

Robots can't work like people.

If you need to emphasize, just add a word like that before these two words. For example:

All plants and animals need air just as they need water.

Mary, like her brother, goes to school at seven every morning.

The difference in meaning is:

(1)like simply means to compare, and it is usually not the same kind of things to compare:

The ship looks like a tall building.

The sky above me is like ink.

(2) As a comparison that can express similar things.

This ship is as long as that one.

Second, when "just like ..." means spoken English, the grammatical structure is different:

(1)as is a relative pronoun or adverb, leading a clause.

In such a sentence, as refers to the content of the whole sentence, which leads to a non-restrictive clause, usually serving as the subject or object in the clause. For example:

As mentioned earlier, metals have many good properties.

As we said before, you did a good job.

(2)like as a preposition.

Like thousands of others, she was fascinated by this work.

Third, as and like can sometimes be used interchangeably.

(1) In informal American English, like can be used as a conjunction instead of as. For example:

No one loves you more than I do, baby.

(2) In informal style, like is often used instead of if.

Duke said, "You think you can reach out and touch it."

4.as is often used in the following phrases: In the phrases as you know, as we agree, as you suggested, the actual meaning of as is not comparison or similarity, but the meaning of the same thing or person. For example:

You know doesn't mean that you know such things, but that you know such things.

As he knows, she is not very good at writing letters.

As all his friends agree, he is extremely warm-hearted, lovely and generous.

Like can sometimes be used in this phrase in informal questions, but it is rare in English used by educated people.
