Who knows where to get an original summary, not one provided by the author for free? Please, I need it for a book called Ogadimma, The Diary of a Househelp by Chinelo Nicole.

which speech are you talking about?

a. "to practice" is the best phrase to complete the sentence.

explanation:

during the summer, she likes to practice her soccer skills so that she is ready to play in the fall.

(note that : all the other options "the practicing of", "practice for" and "to do a practice on" are inappropriate as they make the sentence grammatically incorrect.)
