I have to think
They're both correct in the appropriate context. From your question I can't decipher context so can't really say.
yeah , i think is correct say a lot of thanks for quick response...
no it is not a correct sentence.
This is not a sentence it is a phrase and as a phrase it is correct.
The sentence, "They are going to the beach." is correct.
The sentence "I think I catch a cold" is not grammatically correct. It should be written as "I think I am catching a cold" to indicate the present progressive tense.
like you can say example: hey do you think i wrote a good sentence?
Yes. Think about it in a sentence. "Is he in the seat?"
first i think no then i think yes
They're both correct in the appropriate context. From your question I can't decipher context so can't really say.
No, I think the correct way is- Is this the first time you've seen it?
The correct sentence is "Give the award to whomever you think is best."The pronoun "whomever" is the objective form, functioning as the object of the preposition "to".The pronoun "whoever" is the subjective form.
"How are you" is a correct sentence.
Yes, it is grammatically correct to end a sentence with the word "so." However, it may be informal or conversational in style.
yeah , i think is correct say a lot of thanks for quick response...
the dinosaurs' heads there i think.
If you put a question mark after it I think it is.
