Thank you for your help. One more similar patterns goes.
1. The heavy rain made it difficult for me to open my eyes.
2. The loud music made it difficult for me to focus on my study.
3. The heavy snow made it difficult for me to ride a bike.
1-1. The heavy rain made it difficult that I opened my eyes.
2-2. The loud music made it difficult that I focused on my study.
3-3. The heavy snow made it difficult that I rode a bike.
-------------------------------------- Are they all grammatical? Would you correct some errors?
1, 2, and 3 are fine. 1-1 should be "The heavy rain made it difficult for me to open my eyes. 1-2 "The loud music made it difficult for me to focus on studying." 1-3 "The heavy snow made it difficult to ride a bike."
