About 90% of English words are composed of roots, prefixes and suffixes, which are difficult for students to remember. The future vocabulary of postgraduate entrance examination, TOEFL vocabulary and specialized foreign language vocabulary are also inseparable from the root. I did an experiment in which students memorized three groups of words of the same clan (that is, the same root) in 10 minutes, with about 30 words. Later, the exam results were very good, even the students with poor academic performance were poor. Band 4 vocabulary needs about 150 roots, which can be expanded to nearly 2000 words. Add 1800 words from senior high school, which can basically meet the vocabulary required by Band 4. Here, we will introduce the roots with strong word-formation ability in each unit vocabulary of Contemporary College English that we have learned. So as long as you spend 10 minutes reciting one unit of words every day, and then spend 10 minutes testing yourself, I believe your vocabulary will be different in 50 days! And you have learned a kind of ability-guessing words, which is a lot of money for your future self-study, development and further study. More importantly, the words memorized in this way are not easy to forget!
