After looking through the sentence comparison examples, what do you think the guidelines are that tell you when to use the different forms of "you?" Write down your thoughts about this grammar principle. Specifically, write down a "rule" that you think Spanish uses to explain the difference between tú and usted.

- 'tú' and 'usted' both mean 'you' in Spanish but 'tú' is comparatively less formal

Explanation:

The two different terms 'tú' and 'usted' in Spanish mean the same i.e. 'you' and they both are employed to denote a formal relationship. However, the difference between the two terms is that the former(tú) is less formal as it is used while talking to a known person or someone who is of your rank, age or younger than you. 'usted', on the other hand, is more formal and employed during a conversation with an unknown or elderly person to display respect towards him/her.

i would lay on the ground, and wait for the earth to simply take me back!

- sincerely, ouma

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.)
