Choosing a big composition without writing a topic will lose points. Choosing the topic of argumentative essay according to relevant information is different from the topic of composition. In high school, the Chinese teacher emphasized that the composition should be written in half, but in the selection exam, the topic is not as important as expected, because it is given separately and the grading method is quite simple and rude: deducting two points without title is a common question type in the civil service selection exam, which accounts for a heavy score. Candidates who take part in the civil service selection examination in various places must carefully grasp what elements are needed for an excellent analytical theory and practice writing more.
