Answer:
You have a fever and should lie down.
The team's morale was effected after the loss.
Thank you for lending me your notebook; may I also borrow a pen?
Step-by-step explanation:
- He laid down after the game for a nap.
Lay means "to place something down flat," while lie means "to be in a flat position on a surface." In this case, he is the one moving into the position, so "laid" is incorrect.
- You have a fever and should lie down.
Same application as the previous phrase. You are the one moving into the position, so "lie" is the correct term.
- The decorations loaned an air of celebration to the cafeteria.
"Loaned" means to lend something to someone. The decorations did not let the cafeteria borrow celebration.
- The team's morale was effected after the loss.
Affected means that something was influenced or changed. Effected means that something was brought about or facilitated. In this case, the team's morale was changed or influenced by the loss, so affected is the correct term.
- Thank you for lending me your notebook; may I also borrow a pen?
This is correct, as "lending" means to allow someone to borrow something.
- Please sit your books on the shelf, and then take out a pen for a quiz.
"Sit" is used when talking about occupying a seat metaphorically or physically taking a sitting posture. "Set" is used when talking about an object or place. Because the books are what are being referred to, "sit" is incorrect.
