In the United States,most children begin attending school when they are 5 years old.Public education is free and most children go to learn to read and write.But they also play games and go on trips.There is no reason at such an early age for them to hit the books.
The situation changes as children become older.The subjects become more difficult. Students must learn about world history,algebra(代数),and the life sciences.Tests become more common.Pressure is growing to hit the books,study hard,and advance.However,most serious students only really begin hitting the books for long hours when they reach high school.
High school students who hope to continue their education at a college or university must take a special national test called the S-A-T.The test has two parts.The first part tests the students’ ability with numbers and mathematical skills. The second part tests the students’ ability in the English language.
