Complete the sentence with the correct form of the verb in brackets: "I have never ____ (see) the harbour so calm at this time of year."

seen
توضیح
"Have never" is a present perfect, so the verb goes into its past participle form, which this verb builds with -en. The past simple saw belongs in sentences that report a single finished moment without an auxiliary, such as a plain account of last weekend.
