hey dear what do you think is it correct here?( choosing) i think no need for ing Verb ??
i think you should use simple form of the verb i mean choose
choose a name for my company is getting difficult for me
what do you think about this sentence ?
i think when we use ing verb we should use to be too but here no to be verb need at the first
it's my idea
but i am not sure
masters should tell it

There is nothing wrong with that structure, it also is very common
we usually use verb+ing at beginning of sentences to show two actions are occurring at same time
It also prevents repeating starting every sentence with "he" or "she"
It has other usages but I'm in no mood for explaining more, you can search on the internet
Good Luckl

1. Use of the present perfect
The English Present Perfect tense is used to express actions which have already been completed, or perfected, at the time of speaking or writing. In the examples given below, the verbs in the Present Perfect tense are underlined.
e.g. I have done the work.
She has answered half the questions.
In the first example, the use of the Present Perfect tense emphasizes the fact that, at the time of speaking or writing, the work has already been completed. In the second example, the use of the Present Perfect indicates that, at the time of speaking or writing, half the questions have been answered

2. Formation of the present perfect: Regular verbs
The Present Perfect tense of any English verb is formed from the Simple Present of the auxiliary to have, followed by what is generally referred to as the past participle of the verb.
Most English verbs form the past participle in a regular, predictable manner. These verbs are commonly referred to as regular verbs.
The past participle of a regular English verb is formed by adding the ending ed to the bare infinitive of the verb. For instance, the past participle of the verb to work is worked.
Thus, the Present Perfect tense of the verb to work is conjugated as follows:
I have worked
you have worked
he has worked
she has worked
it has worked
we have worked
they have worked
The present perfect continuous
a. Use
The Present Perfect Continuous tense is used to express continuous, ongoing actions which have already been completed at the time of speaking or writing.
In the following example, the verb in the Present Perfect Continuous tense is underlined.
e.g. The bus has been waiting for one hour.
The use of the Present Perfect Continuous tense in this example indicates that, at the time of speaking or writing, the bus has completed one hour of continuous waiting.
b. Formation
The Present Perfect Continuous tense of any English verb is formed from the Present Perfect of to be, followed by the present participle of the verb. For instance, the Present Perfect Continuous tense of the verb to work is conjugated as follows:
I have been working
you have been working
he has been working
she has been working
it has been working
we have been working
they have been working
Thus, it can be seen that the Present Perfect Continuous tense has two auxiliaries. The first auxiliary is have or has, and the second auxiliary is been.
The past perfect
a. Use
The Past Perfect tense is used to refer to a non-continuous action in the past, which was already completed by the time another action in the past took place. In the following examples, the verbs in the Past Perfect tense are underlined.
e.g. She had heard the news before I saw her.
I had finished my work by the time the clock struck twelve.
In the preceding examples, the verbs had heard and had finished are in the Past Perfect tense, and the verbs saw and struck are in the Simple Past. The use of the Past Perfect tense indicates that the actions of hearing the news and finishing the work were already completed by the time the actions expressed by the verbs in the Simple Past took place.
b. Formation
The Past Perfect tense is formed from the Simple Past of the auxiliary to have, followed by the past participle of the verb.
The Simple Past of to have is had. In spoken English, the auxiliary had is often contracted to 'd. For example, the Past Perfect of the verb to work is conjugated as follows:
Without Contractions
With Contractions
I had worked
I'd worked
you had worked
you'd worked
he had worked
he'd worked
she had worked
she'd worked
it had worked
it'd worked
we had worked
we'd worked
they had worked
they'd worked
The contraction it'd is less frequently used than the other contractions, since it is more difficult to pronounce.
The past perfect continuous
a. Use
The Past Perfect Continuous tense is used to refer to a continuous, ongoing action in the past which was already completed by the time another action in the past took place. In the following examples, the verbs in the Past Perfect Continuous tense are underlined.
e.g. I had been waiting for two months by the time I received the reply.
He had been thinking about his friends shortly before they called.
In the preceding examples, the verbs had been waiting and had been thinking are in the Past Perfect Continuous tense, and the verbs received and called are in the Simple Past. The use of the Past Perfect Continuous tense indicates that the actions of waiting and thinking were continuous, and were completed by the time the actions expressed by the verbs in the Simple Past took place.
b. Formation
The Past Perfect Continuous tense is formed from the Past Perfect of the auxiliary to be, followed by the present participle of the verb. For example, the Past Perfect Continuous tense of the verb to work is conjugated as follows:
I had been working
you had been working
he had been working
she had been working
it had been working
we had been working
they had been working
The auxiliary had is often contracted to 'd in spoken English.
