Conversation 对话
Anna: Hello! Washington, D.C. sits on the
Potomac River. This river is important to the history and culture of the city. Today, I am at an outdoor
seafood market near the Potomac River. Some say it is the
oldest outdoor seafood market
in the United States! I am here to buy seafood. Let’s see what they have!
Anna: Excuse me. Can you help me?
Pete: Sure! What do you need?
Anna: Pete!
Pete: Anna!
Anna: What are you doing here?
Pete: I work here. You know, it’s not easy to be a writer.
Anna: Yeah, I heard that. Sorry.
Pete: But this job is great. I work outside by the river. And I can eat all the free seafood I want!
Anna: That is great, Pete. In fact, I am here to buy some seafood for my dinner party.
Pete: You came to the right place. They have the freshest seafood in town. How much money can you spend?
Anna: I can only spend $50.
Pete: Okay. What do you want?
Anna: First, I want to buy some shrimp.
Pete: Sure thing. Follow me. How much shrimp do you want?
Anna: How much do I need for five people?
Pete: (yells to co-worker) Give her a pound of shrimp!
Anna: Ok, now I want to buy some crabs.
Pete: The crabs here are delicious! They are the best because they come from the nearby Chesapeake Bay! Walk this way.
Pete: How many crabs do you want?
Anna: I want a dozen crabs.
Pete: You should get the larger crabs. They have the most meat.
Anna: Then I want a dozen large crabs, please!
Pete: Is that everything you need?
Anna: Let’s see … I have shrimp and crabs. And a friend is bringing a salad and many ears of corn-on-the-cob.
Pete: Is that all the seafood that you need?
Anna: Yes.
Pete: That’ll be $49.95. Cash or credit?
Anna: Credit, please.
Pete: Anna, you love to eat seafood. Did you grow up on the water?
Anna: No, I didn’t. But I love the water. And I love being on the water.
Pete: You know how to sail?
Anna: Well … this afternoon I am going on a boat.
Pete: You are full of surprises. What kind of boat? Is it a motorboat or a sailboat?
Anna: It’s a special boat, Pete. Well, thanks for your help. See you later!
Pete: See you, Anna! Wow, Anna’s a sailor! Who knew?
Anna: Yes, rivers are important to the history and culture of Washington, D.C. And now I am part of this city’s interesting waterfront culture. Until next time!

Learning Strategy 学习技巧
Learning Strategies are the thoughts and actions that help make learning easier or more effective.
The learning strategy for this lesson is Make Inferences . Making inferences means using some information to make a guess. When learning a new language, we often need to guess at the meanings of words or sentences.
本课的学习技巧是做出推论，也就是利用已知信息进行推测。学习外语时，我们经常需要推测单词或句子的意思。
In this week's video, Pete guesses that Anna grew up on the water. He says, "Anna, you love to eat seafood. Did you grow on near the water?"
在本课视频中，Pete猜Anna是在水边长大的。
Anna answers, "No, I didn’t. But I love the water. And I love being on the water." Pete hears that and uses the information to make an inference about Anna. He asks her, "You know how to sail?"
Anna说自己不是在水边长大的，但是很喜欢有水的地方，也喜欢出海。Pete听到后，再次推测，问Anna是不是会航行。
Can you find another place in the conversation when Pete makes an inference? Do you ever make inferences when listening to or reading English? Write to us about it in the Comments section or send us an email. Teachers, see the Lesson Plan for more details on teaching this strategy.
你还能在课文中找到Pete做出推断的另外一处地方吗？你在听英语或是阅读英语文章的时候，会不会用到推断的技巧？评论或发邮件告诉我们。
