Exercise on Unity and Completeness

Should not Bring Mobile Phone to School
Recently most people own mobile phone. Why does mobile phone user increase dramatically in recent years? First, the feature and functions have increased. Mobile phone is not used just for calling, but sending text, taking pictures, recording videos, accessing internet, playing games and much more. Second, mobile phone has also become a lot cheaper. Now this communication device does not only fill the pocket of adult but also teenager and student. This device is even produced with complete software that can spoil the users in their spare time. Even a lot phones are intentionally designed to teenaged market. However should they be allowed to bring them to school? Many schools do not allow students to bring cell phones to school. It is very reasonable because bringing phone to school potentially disrupts the learning process. Most students use cell phones irresponsibly. They use cell phones to talk to their friend during class time. They also use the calculator and camera features in the class as well. Those potentially lead less concentration in learning and teaching process. Some features in mobile phone also help users in finishing some tasks.
Students go to school to learn and behave fair way. Mobile phones provide a large temptation to cheat in tests. They can communicate to anyone in almost everywhere in the world. Because of the small size of the cell phone, students can send a text quietly and discreetly. The text can go unnoticed anywhere to get help on answering tests, homework, and other class assignment. Learning in school is to behave fair not cheating.
Therefore, schools should ban students from bringing their cell phones. However it should be done fairly. In case of an emergency some student need a call for help, providing easy access to phone is better. The usage of mobile phone has been considering to be one of main equipment in students’ life.

Giving Children Homework
There are a lot of discussion as to whether children should be given homework or not. Is it enough for children having time to study at school or needing additional time in home for study after school time? Some people claim that children do enough work in school already. They also argue that children have their hobbies which they want to do after school, such as sport or music. A further point they make is that a lot of homework are pointless and does not help the children learn at all. However, there are also strong arguments against this point of view. Parents and teachers argue that it is important to find out whether children can work on their own without the support from the teacher. They say that the evening is a good time for children to sit down and think about what they have learned in school. They can even watch their favorite TV program at the same time. Furthermore they claim that the school day is too short to get anything done. It makes sense to send home tasks like independent reading or further writing task which do not need the teacher support. On the other hand, some homework is good idea but that should only given at the weekend when children have more time.
