Working in a group is better than working alone Study efficiency, especially related to the knowledge accumulation, has aroused discussions and even debates over the approaches of how students acquring a wide range of knowledge in a short period of time. Study independently, in many people’s opinions, makes students focusing better on their assignments and solving acadamic problems quickly. Contrary to these people’s views is my perspective that working in a group is much more effective than working alone, due to its contribution to gain assitance from group members and reduce mistakes.

What must be prioritized is that compared with working alone, woking in a group enable students to exchange different opinions, share the workload, which will ensure a higher leaning quality. Initially, we can never ignore that students are more likely to share various ideas and learn faster when workng in a group. Specifically, every individual only has limited knowledge, students are able to enlarge their knowledge base by accomplishing the assignments in a group. How can working alone provides students with the access to considerable knowledge in a relatively short period of time?Moreover, only can students learn the importance of spliting tasks through wroking in a group.To be more specific, students can not only assume their own resiponsibilitie, they can also learned how to distribute the tasks and cooprate with other people; besides, working alone means all the tasks has to done by only oneself which is a waste of the time. For instance, a student in The Affilicated High School of Peking University, he often take part in the variety of group activities at school, such as field observation of wild insects and plants. not merely did he learn a lot of knowledge of many kinds of animals and plants rapidly, but he also completes his part of task in just two days with the help of all the group members.

What is equally woth discussing is that compared with working alone, working in a group will reduce the errors, thus learning more effectively. First, we can not deny that ideas made by other perspentives are more objective. To be more specific, every single group member will express their perspectives in the process of group discussion, in this way, students are more likely to locate the puzzles and settle the problems; otherwise, views made by individuals are more likely tending to be wrong since it’s very subjective. Additionally, it is involved in a group that contributes to gain more compenhensive information, in order to reduce the errors caused by inadequate understanding of acadamic knowledge. In detail, only can students acquire diverse informations provided by all the group members when participating in a group activity, while working alone might spend more time and acquire less knowledge. Never can woking alone obtaining the compenhensive information, due to shortage of information resources. Take a student who majoring chemistry in University of California for example. He likes to engaged in group experiment and group discussion, in this process, he’s able to discover the problems in his chemical experiment with the help of other group members, also they offered some constructive suggestions in order to avoid the dangerousness of faulty operation.

Students, the future of society, they are more likely to learn faster when working in a group, as illustrated in the example of the student in The Affiliated High School of Peking University. Mistakes, will be reduced in a group, as clarified in the instance of the student in the University of California.In conclusion, only by working in a group, can students accomplish their assignments efficiently, which will ensure their study efficiency.

Any grammar mistakes? Perosaurs would not have been able to generate the energy needed to fly because it’s cool-blooded animal which have a slow metabolism and are unable to produce a lot of energy.

Recently reasearchers found that pterosaur fossils had something similar to fur which is a typical feature of warm-blooded animals. Hair or fur can maintain a high body temerature of animals, especially when the days getting cold. So the metabolism of pterosaurs might supply the energy needed for powered flight.
