Both the reading and the speech focus on the function of mega buildings of Chaco Canyon. The former believes that there are three possible theories to explain the useage of the buildings whereas the latter cast doubt on each of the theories.

To begin with, the first theory is that Chaco structures were residential which could hundreds of residents. Nevertheless, the lecture argues that if they were for living propose, there should be a lot of fire places and that ,as the evidence shows, the massive building could contain hundreds of families but only ten fire places were found at the sites which could not have been residential use.

In addition, there comes the second theory that the buildings could archive food supplies. In contrast, the lecturer demonstrates deep opposition to such a claim, by stating that excavation at the sites does not show any provement of maize remains or maize containers. There is absent evidence to support the second theory either.

At last, another probable explanation is that these houses were ceremonial centers with the finding of broken pots. Conversely, as the speaker affirms, other materials were found beside the broken pots such as sand, stone, construction tools which strongly improve that these were rubbish threw away by the workers after the buildings were finished, turning out that the third theory is groundless.

Teachers are those people who sacrifice all their time to educate others. Most of them devote their whole lives in distributing knowledge whom we all should show respect to. However, nowadays many students with bad manner perform terribly toward their teachers which cannot be expected and allowed in the past.

Dating back to nineteen century in China, teachers were very scarce sources. One teacher almost needed to be responsible for two or three classes thus the time for individual instruction divided by the base number of students. It is the rarity that let teachers had higher status among nineteen century. Every student at that time was eager to have chances to communicate with his or her teacher. They precious every second on the class, asking questions, participating in discussion and absorbing knowledge. Grave expression came into everyone's face.

In comparison, today's students do not treat their teachers like this way. Absence from class and cheating in the exam become some sort of commonplace. Take a glance at my roommate Jessica, she always drops her classes. Once I asked her 'Why are you absent from classes so frequently?'.'Well, the classes are really boring. I can use the time to play with my friends and attend many parties' she said without any sense of guilty. The thing she ignores is that how hard and painstaking teachers prepare for the class. If she were the teacher, seeing half of the classroom was empty how disappointed would she be? Moreover, cheating in the exam, a behavior of lacking honesty becomes much more common among students. When teachers are supervising the exam, they will at least find two or three students cheating in the exam. They may take this as their responsibility for not conducting students to be honest.

In addition, some students become bad to worse even make some tricks on their teachers. One of my teachers was unfortunately suffered from it. She is our chemistry teacher who just graduated from university. The first day she showed up in our classroom was really a tragedy. She was stumbled by a broom as soon as she stepped into the classroom. Seeing how embarrass she was, some of the naughty boys laughed loudly and sarcastically. There is no worse disrespect than this.

It is totally chilling phenomena which should catch parents' eyes to introspect how to educate their children to behave well. Teacher is a noble profession which needs everyone's respect.
