VI. Read and decided if the following sentences are true or false: (1.5pt) There is a question as of why students from famous universities are so smart. The answer lies in their study habits, which should be developed by all students from early ages with help from parents and schools. First, a habit of frequent reading is what children should have. It is understandable if a child does not like reading in his early life. What parents and teachers should do is to explain the importance of daily reading to children. Simply, parents can encourage their children to bring books in their handbags to read in their leisure time. Teachers can share their book picks with their students. Second, writing daily is one of the most essential skills for any students, so they should be provided with opportunities to express themselves in writing and not scared of being marked by their teachers. Thanks to daily writing, their writing ability will be improved. Third, parents should encourage their children to question their teachers.
