The weather is unusually cold.

It is very cold in winter.

Fill in the following contents correctly:

It was very cold last winter.

Was' is the past tense, but this sentence is also the past tense, which is a perfect match. Many people always make this little mistake, that is, fill in with' yes'. If you use' yes', it is completely wrong.

"Last" means last year.

To tell the truth, the translation of this sentence is incomplete, and the following is a complete and correct translation:

It was very cold last winter.
