Question

Подчеркнуть причастие look:she is poisting a parcel

Answer 1

Причастие - is poisting. Не знаю,правда, входит форма глагола 'to be' или нет.

Answer 2

There are a couple of ways to interpret the instruction "underline the participle 'look'". Assuming you meant "underline the present participle form of the verb 'look'" in the sentence "She is posting a parcel", the present participle form of the verb "look" would not appear in this sentence.

However, if you meant to underline the present participle form of a different verb in the sentence, here are a few examples:

• She is looking at the address on the parcel before posting it.
• She is carefully looking over the instructions for posting the parcel.
• She is looking forward to the recipient receiving the parcel.
