1. I (cut) ________ some flowers from my garden yesterday. I (cut) ________ lots of flowers from my garden so far this summer.

Okay, let's look at the first sentence. The first blank needs a verb form of 'cut' in the past simple because of 'yesterday'. So, the answer is 'cut' since the past tense of cut is cut. The second blank needs a present perfect tense because of 'so far this summer'. So, the answer here is 'have cut'. Therefore, the answer is: 1. I cut some flowers from my garden yesterday. I have cut lots of flowers from my garden so far this summer.
