Grammar explanation
as and like are often confused since they can both be used for comparisons. There are, however, important differences.
Making comparisons
as + adjective + as and as much as
We often use the structure as + adjective + as or as much as to say if something has, or doesn't have, the same amount of that quality as something else.
She loves curry as much as I do.
He's not as tall as his brother.
It's not as expensive as the other hotel.
That dog is as big as that child!
You also have to use as in the expression the same as.
Your phone is the same as mine.
Texting is not the same as speaking in person.
like + noun
In the following comparisons, like is followed by a noun or a pronoun to say that two things are similar.
He's like a father to me.
She's acting like a child.
It's like a burger but with big mushrooms instead of bread.
There are lots of people like us.
It is also common to make comparisons using like with verbs of the senses.
She looks like her mother.
It sounds like a cat.
Nothing tastes like homemade lemonade.
It smells like medicine.
It feels like cotton.
as if/as though + clause
As if and as though can be used to compare a real situation to an imaginary situation. They are followed by a clause (a subject and verb).
You look as if you've seen a ghost.
I felt as if I was floating above the ground.
You talk as though we're never going to see each other again.
Giving examples
We can say like or such as to give examples.
You could try a team sport like football, basketball or hockey.
You should take something soft, such as a towel, to lie on.
Talking about a job or function
We can use as + noun to talk about a job or function.
I worked as a shop assistant for two years.
He used his coat as a blanket to keep warm.
as to connect two phrases
as can be used as a conjunction to connect two phrases. It can have different meanings.
as = 'because'
All the tickets were sold out as we got there too late.
As the road was closed, I had to park on the next street.
as = 'while' or 'during the time that'
She called as I was getting out of the bath.
As they were arriving, we were leaving.
as = 'in the way that'
As we expected, it started to rain.
As you know, classes restart on 15 January.
As I said, I think this project will be a challenge.
** Note that in informal speech, people sometimes say like for 'in the way that'.
Like I said, I didn't know her.

Hello itspb008,
Both like and as if can be used for comparisions to real and imaginary situations.
The difference between like and as if is one of form rather than meaning. In traditional grammars, like is a preposition and as (if) is a conjunction. That means that like should be followed by an object - a noun phrase or pronoun, for example, rather than a clause, while as (if) should be followed by a sentence containing a verb phrase. However, this distinction has largely disappeared in all but the most formal writing, I would say, and in modern English like and as (if) are used interchangeably.

Hello Chihchieh
Yes, in informal speaking or writing, that is fine. As it says near the bottom of the Grammar explanation:
Your sentence is a good example of this.

Hello ozgecrbc,
The differences between because and as are small and really deal with whether the speaker is placing emphasis on the reason for something or the result. You can read more about it on this page:
https://dictionary.cambridge.org/us/grammar/british-grammar/as-because-or-since
While suggests that one action was already in progress when another action occurred or began. For example:
Here, the act of speaking on the phone begins before his arrival and is in progress when he arrives.
When tends to be used when two events occur at the same time, or start at the same time. This is why when tends to be used with simple forms rather than continuous. For example:
Here, dinner does not begin until he arrives. The implication is that we were waiting for him and did not want to start until he arrived. The two actions form a sequence rather than occurring simultaneously.
It is possible to use when with a similar meaning to while when there is a continuous verb:
As describes simultaneous actions. One action can occur during an already in-progress action (as with while) if a continuous verb is used, or the actions can occur at the same precise moment when simple forms are used:
We do not use as to describe sequential actions.

Hello Kaisoo93
It's strange to use 'as' here, since really AI is not emotional at all; if you use 'as', it implies that AI can experience emotions at least a little bit. The second sentence could be correct, but please note you'd need to change 'human' to 'humans'.
What I'd recommend is something like 'AI performs better than humans because it is not emotional like humans are' or 'AI performs better than humans because it is not impeded by emotions'.

Hello lidyakim,
Both questions are answered with as. However, the first question needs to have a capital lettter so you need to choose As rather than as.
I'm not sure why the second question was marked incorrect when you chose as. I tested the task myself and it accepted the answer as correct. Please try again to see if you still have a problem.

Hello lidyakim
Your sentence is grammatically correct, but I would recommend changing it to the singular. In other words, instead of 'Russian girls', I'd say 'a Russian girl'. And really, if you want to compare your face to the face of a Russian girl, it'd be better to say 'a Russian girl's' (which means 'a Russian girl's face').
The same would be true with other objects. For example, if you want to compare your face to a rose, it'd be better to say 'as beautiful as a rose' instead of 'as beautiful as roses'.
Does that make sense?
All the best

As an example, let's say you wanted to make a comparison to a flower, for example, a rose. It would be more natural to say 'as beautiful as a rose', or, if you wanted to speak about a lot of roses, 'as beautiful as a bunch of roses'
Hello Akashtigile,
The pages have to be somewhat limited in scope as otherwise they would become extremely long and their usefulness would be compromised.
We're happy to try to help out with particular examples. However, some of the phrases you mention could refer to a range of structures, however. For example, such...as can be used to introduce an example (I want to get a friendly dog, such as a golden retriever or a labrador) or to introduce a particular type of comparison (It was not such a difficult conversation as I had imagined).
If you have any questions about the phrases you mentioned then please provide an example sentence and we'll be happy to comment on it. That way we can be sure that we are addressing the issue you have and not some other use.

Hello sihamkaddouri
There is no real difference in meaning between 'as if' and 'as though' -- they mean the same thing and are used in the same way. The only real difference is that 'as if' is a little more informal than 'as though'.
