You are learning reservations: you will read the scene it happens in, learn 10 words and phrases, take apart the pattern behind them (需要 / 可以 + verb — making requests), hear them in a conversation, rehearse them, and finish by saying one thing out loud to be graded.
Calling to make a reservation at a popular Shanghai restaurant
今天晚上我们要去鼎泰丰吃饭，但是鼎泰丰总是很忙。我决定打电话订位。
我打了电话。「你好，我需要订位。今天晚上七点，三个人。」服务员说「请等一下，我查一查。」
过了一会儿，服务员说「对不起，七点满了。八点可以吗？」我想了想，说「可以。有没有包间？」她说「包间也满了，但是有大厅的位子。」
我说「好的，大厅可以。我姓王。电话号码是138-1234-5678。」她说「好的，王先生，八点三位，已经确认了。」太好了！预约成功。
