Five years ago, when I taught art at a school in Seattle, I used Tinkertoys as a test at the beginning of a term to find out something about my students. I put a small set of Tinkertoys in front of each student, and said:”Make something out of the Tinkertoys. You have 45 minutes today - and 45minutes each day for the rest of the week.”

A few students hesitated to start. They waited to see the rest of the class would do. Several others checked the instructions and made something according to one of the model plans provided. Another group built something out of their own imaginations.

Once I had a boy who worked experimentally with Tinkertoys in his free time. His constructions filled a shelf in the art classroom and a good part of his bedroom at home. I was delighted at the presence of such a student. Here was an exceptionally creative mind at work. His presence meant that I had an unexpected teaching assistant in class whose creativity would infect(感染) other students.

Encouraging this kind of thinking has a downside. I ran the risk of losing those students who had a different style of thinking. Without fail one would declare, ” But I’m just not creative.”

“Do you dream at night when you’re asleep?”

“Oh, sure.”

“So tell me one of your most interesting dreams.” The student would tell something wildly imaginative. Flying in the sky or in a time machine or growing three heads. “That’s pretty creative. Who does that for you?”

“Nobody. I do it.”

“Really-at night, when you’re asleep?”

“Sure.”

“Try doing it in the daytime, in class, okay?”

The teacher used Tinkertoys in class in order to（）?

A. know more about the students

B. make the lessons more exciting

C. raise the students’ interest in art

D. teach the students about toy design

某高档酒店的贵宾包厢里，酒店的合作伙伴某旅游公司的李总请客。李总点了 2瓶茅台酒，2瓶红葡萄酒，几听饮料，1条中华香烟。服务员小王听后马上去吧台取酒，拿到包厢工作台上后，小王就利索地将红酒打开，并主动地从主宾位开始斟酒。当给李总斟酒时，李总说；“等等，我点的好像不是这种酒嘛，你看怎么办？”小王慌了，说：“先生，您点的就是这种酒，不会错的。”李总看了看小王，说；“算了算了，就这个吧。”这桌客人尤其喜欢吸烟，包厢里烟雾缭绕。服务员小王觉得站在包厢里闻着烟味不舒服，便退到了包厢外面，当有菜送来时才进去上菜。因此，包厢里的情景不堪入目：每位客人面前的骨碟都堆得满满的，有的甚至都溢出来了；烟灰缸里既有烟蒂又有吃剩的骨头；客人们在相互给对方倒酒；有位女士想点2盒酸奶，叫了几声服务员，却没有回应；桌面上空盘、空饮料瓶显得很抢眼。酒店总经理过来敬酒，看到这一幕以后觉得很没有面子，忙陪酒道歉，马上叫服务员小王整改。请问：

开红酒前小王犯了什么错？根据酒水服务规范，服务员开整瓶的葡萄酒和烈性酒前应怎么做，为什么？（5分）
