A、Go to summer school. B、Take a vacation. C、Stay at home. D、Earn some money. D这段对话通篇都是围绕着暑期打工这个话题，“job”和“paid”反复出现，显然，M希望在暑假找份兼职

M:I really don’t know what to do this summer. I can’t afford to just sit around, and there don’t seem to be any jobs available.
W:Why don’t you try house-sitting? Last summer my friend Margaret house-sat for the Dodds when they went away on vacation. Mr. Dodd hired Margaret to stay in their house because he didn’t want it left empty.
M:You mean the Dodds paid Margaret just to live in their house?
W:It wasn’t that easy. She had to mow the lawn and water the house plants. And when Eric house-sat for Mr. Cohen, he had to take care of her pets.
M:House-sitting sounds like a good job. I guess it is a little like baby-sitting—expect you’re taking care of a house instead of children.
W:The student employment office still has a few jobs posted.
M: Do I just have to fill out an application?
W: Margaret and Eric had the interview with the homeowners and provide three references each.
M:That seems like a lot of trouble for a summer job.
W:Well, the homeowners wants some guarantee that they can trust the house sitter. You know they want to make sure you’re not the type who’ll throw wild parties in their house, or move a group of friends in with you.
M:House sitters who do that sort of thing probably aren’t paid then.
W: Usually they’re paid anyway just because the homeowners don’t want to make a fuss. But if the homeowner reported it, then the house-sitter wouldn’t be able to get another job. So why don’t you apply?
M:Yeah, I think I will.
1. What does the man want to do this summer?
2. What did the Dodds do when they went away last summer?
3. What is one responsibility the house sitter probably wouldn’t have?
4. How do homeowners determine the reliability of a house sitter?
