Q: Article: Roughly speaking, teachers in traditional education may feel that students are too young to know much about the world, and have to be told what to do most of the time. By contrast, open education offers teachers quite different feelings. Students are expected to be responsible for their own education--to discover subjects by themselves instead of being made to study them. This way of teaching allows the students to grow independently and to develop their own interests in many subjects. Some students who do badly in a traditional classroom will be happier in an open classroom and enjoy learning. They will not have to worry about grades or rules at all. However, many students won't do well in an open classroom. For these students, they will do little in school if there are too few rules. They will not make good use of open education, which is so different from traditional class, because they may have a problem getting used to making so many choices on their own. For them it is important to have some rules to direct them. They may worry about the rules even when there are no rules. In addition to that, some traditional teachers do not believe in open education and do not like it either. Since both of some good points and bad points of the open education have been explained clearly, you may have your own opinion on the issue. Personally, I think that the concept of open education is good only in theory. In actual fact, it may not work very well in a real class or school. I believe, most students, but of course not all students, need some structure in their classes. They may want and need to have rules. In some cases, they must be made to study some subjects. Many students are pleased to find subjects they have to study interesting. They would not study those subjects if they did not have to.
Question: Open education allows the students to _ .
Options: (A) grow as the educated (B) be responsible for their life (C) discover subjects outside class (D) develop their own interests

Q: Article: When you don't speak, you may be still communicating. It is true that you may not wish to say anything. But your very silence may show your wish to be left alone or to stay uninvolved, which is the message you want to send. So it has been said that while we speak with our vocal organs, we _ with our whole bodies. All of us communicate with one anther nonverbally , as well as with words. Sometimes we know what we are doing with the use of gestures such as the thumbs-up sign to indicate that we approve. But most of the time we are not aware that we are doing it.

Loudness and tone of voice is an example here. Thirdly it regulates social interaction: turn taking is largely governed by non-verbal signals. Fourthly it conveys our emotions. Finally it conveys our attitude towards ourselves and towards the people we are communicating with. _ is particularly important for successful cross-cultural communications. Every culture has its own body language. So in order to achieve a more successful cross-cultural communications, we heed not only what to say but also how to say it appropriately.
