How do I look?
How am I looking?
Both the sentences are grammatical.
If you are asking about your appearance or the way you are doing something at the present time; at the time of speaking, you can use either, without any difference in meaning. However, the use of the presrnt simple is more common than the present continuous. Nevertheless, many people use the present continuous for emphasis.
On the other hand, if you are asking about how you always or generally look, you should invariably use the former (the present simple).
The verb "look" in the sentences is a stative/linking verb used in the sense of the verb seem or appear.
According to grammar, we don't normally use stative verbs in the continuous form. But, sometimes, some stative verbs like "look" can be used in the continuous form depending whether the situation or condition we mean is permanent or temporary. You use the present simple for a permanent condition and the present continuous for a condition that's temporary or for a short period of time. For example:
If we say "This shirt is looking nice on you", it's a temporary situation limited to the period of time you are wearing this shirt. However, if we say "you look just like your father", we are referring here to a permanent situation. In the former example, we can use either the present simple or the present continuous, but in the latter example, we use the present simple. (John Eastwood Oxford Practice Grammar).
If this is from an exam or class exercise you may point out to your teacher that any of the options may be correct.
I haven't seen Kumar this week. —As you say, this speaks to the current state of things: it says that you haven't seen Kumar during the part of this week that has already passed, but it leaves open the possibility that you may see Kumar during the part of the week that remains.
I didn't see Kumar this week. —You would use this if the opportunity for seeing Kumar this week has now passed: for instance, if you ordinarily see Kumar on Tuesdays, you might say this later in the week if one of you was otherwise engaged at the time of your usual meeeting.
I am not seeing Kumar this week. —You would use this if an expected meeting with Kumar will not after all take place. For instance, if on Tuesday someone asks you to bring up an urgent matter with Kumar at your regular Thursday meeting, but you know that Kumar is out of town this week, you might say this.
Best Answer
she looks is okay.
This is correct because looks is singular, and the subject she is singular. So it is correct to say:
she is looking is okay, but in spoken English the contraction she's looking would be more common.
If you wish to use looking as part of a verb phrase you need another verb, such as: She is looking, I am looking, or They are looking.
And so you are correct to say the following doesn’t fit:
Look is plural, so you need a plural subject. So it would be correct to say
But incorrect to use it when the subject is singular:
