Words and Useful expressions
Core Literacy Objectives
1 Language Competence
Students can understand and use the target words (e.g., remind, contact, base) in reading and writing contexts, and master common collocations (e.g., be based on, have a frog in one’s throat) to express ideas accurately.
2 Cultural Awareness
Students can identify vocabulary differences between British and American English (e.g., petrol/gas, flat/apartment) and understand the cultural connotations behind such variations, fostering cross-cultural sensitivity.
Core Literacy Objectives
3 Thinking Quality
Students can analyze word-formation rules (e.g., compound words like pineapple, derivatives like creative→creativity) and summarize memory strategies, developing logical and inductive thinking.
4 Learning Ability
Students can use context clues (e.g., guessing unfamiliar meaning via "un-" prefix) and classify vocabulary (reading vs. writing) to improve independent vocabulary learning efficiency.
