Unit 6: Vocabulary and Reading Comprehension

I. Orientation — Meaning-Making in Communication

Vocabulary and reading comprehension are interdependent skills: readers interpret words through context, recognize conventional word combinations, locate information efficiently, and construct meaning beyond what a text states directly.

• Governing principle: Meaning arises from the interaction of the word, its surrounding context, the writer’s intention, and the reader’s prior knowledge.
• Vocabulary knowledge:
  • Breadth refers to the number of words and expressions a person recognizes.
  • Depth includes connotation, register, grammatical behavior, collocations, and figurative uses.
• Reading purposes: A reader may seek the general message, locate a specific detail, evaluate an argument, infer an unstated idea, or remember information.
• Reading levels:
  • Literal comprehension identifies explicitly stated facts.
  • Inferential comprehension draws evidence-based conclusions.
  • Critical comprehension evaluates purpose, tone, assumptions, and credibility.
• Strategic flexibility: Efficient readers change speed and technique according to the text and task; a timetable may require scanning, whereas an editorial requires close reading.

II. Vocabulary in Use — Conventional and Contextual Meaning

Vocabulary competence involves more than knowing dictionary definitions; it includes recognizing fixed patterns, figurative meanings, appropriate combinations, and clues supplied by the text.

A. idioms

Idioms are conventional expressions whose overall meanings cannot usually be determined by interpreting each word literally.

• Figurative meaning: In “The exam was a piece of cake,” the phrase means “very easy,” not a portion of food.
• Fixed or semi-fixed form: Speakers normally say “spill the beans,” meaning reveal a secret; replacing beans with peas destroys the recognized idiom.
• Context and register: “Break the ice” is suitable in everyday or moderately informal communication, while “facilitate initial interaction” belongs to formal writing.
• Literal–idiomatic distinction: “He hit the roof during repairs” may be literal, but “He hit the roof when he saw the bill” means he became extremely angry.
• Effective use: Idioms should fit the situation and audience. Excessive idiomatic language can make academic or international communication unclear.
• Interpretation method: Test the literal meaning against the context, then substitute a plain expression. If “Mina is under the weather and stayed home,” “slightly ill” fits the evidence.

B. collocations

Collocations are word combinations that occur together more frequently and naturally than alternative combinations with similar literal meanings.

• Lexical combinations: English uses “heavy rain,” “strong argument,” and “make a decision”; “strong rain” and “do a decision” sound unnatural.
• Common patterns:
  • Adjective + noun: “serious problem.”
  • Verb + noun: “meet a deadline.”
  • Adverb + adjective: “deeply concerned.”
  • Verb + preposition: “depend on.”
• Meaning differences: The adjective changes according to the noun: “a strong coffee,” “a powerful engine,” and “a heavy workload.”
• Grammatical accuracy: Collocational knowledge includes prepositions, as in “responsible for,” “interested in,” and “capable of.”
• Communication value: Appropriate collocations make language precise and fluent. “The company suffered a loss” is more conventional than “received a loss.”
• Learning method: Record whole combinations rather than isolated words—for example, learn raise awareness as one unit and note the sentence “The campaign raised public awareness.”

C. formulaic expressions

Formulaic expressions are ready-made sequences used to perform recurring communicative functions efficiently and politely.

• Communicative function: “Would you mind…?” introduces a polite request, while “In my opinion…” signals a personal viewpoint.
• Predictable form: Expressions such as “As far as I know” and “On the other hand” are retrieved as units rather than constructed word by word.
• Interaction management: “Could you clarify that point?” requests explanation; “If I may add something…” helps a speaker enter a discussion.
• Academic organization: “The evidence suggests that…” introduces an interpretation, and “In conclusion…” marks the final stage of an argument.
• Appropriateness: “What’s up?” suits informal conversation, whereas “How may I assist you?” fits professional service encounters.
• Limitations: A memorized expression must match the context. Repeatedly using “I totally agree” may sound mechanical when partial agreement—“I agree to some extent”—is more accurate.

D. contextual vocabulary

Contextual vocabulary is understood by using linguistic and situational clues surrounding an unfamiliar or ambiguous word.

• Definition clue: “Arboreal animals, that is, animals living in trees, have specialized limbs” directly defines arboreal.
• Example clue: “Renewable resources, such as sunlight, wind, and flowing water,” allows the reader to infer the category’s meaning.
• Contrast clue: “Unlike his gregarious sister, who enjoyed large gatherings, Arun preferred solitude” indicates that gregarious means sociable.
• Cause-and-effect clue: “The road was inundated, so vehicles could not pass through the floodwater” connects the word with flooding.
• Word-part clue: In misinterpret, the prefix mis- means wrongly, interpret means explain meaning, and the whole word means understand incorrectly.
• Verification: A guessed meaning must fit both grammar and logic. In “The medicine alleviated the pain,” the object pain and the positive result support “reduced,” not merely “noticed.”

III. Strategic Reading — Locating Meaning Efficiently

Strategic reading matches a technique to a purpose: skimming builds a rapid overview, whereas scanning locates a predetermined item without processing every sentence.

A. skimming and scanning techniques

Skimming and scanning are rapid-reading techniques with distinct objectives and patterns of attention.

1. Skimming

   • Purpose: Skimming identifies the topic, organization, and overall message. A reader may preview a report before deciding which section deserves close reading.
   • Attention pattern: Read the title, headings, introduction, topic sentences, emphasized terms, and conclusion. In a five-paragraph article, these features reveal its argumentative structure.
   • Speed: Minor examples and unfamiliar words are temporarily passed over unless they appear central to the message.
   • Outcome: The reader should be able to state a provisional summary, such as “The article argues that urban trees reduce heat and improve public health.”

2. Scanning

   • Purpose: Scanning finds a specific name, date, statistic, definition, or keyword. To locate a train leaving at 18:30, the reader searches the time column rather than reading the entire timetable.
   • Attention pattern: Anticipate the item’s visual form—digits for a percentage, a capital letter for a surname, or a currency symbol for a price.
   • Keyword matching: Search for synonyms as well as exact wording; information about “employment decline” may appear under “job losses.”
   • Contrast: Skimming asks, “What is this text generally about?” Scanning asks, “Where is the particular information I need?”

IV. Comprehension and Interpretation — From Evidence to Understanding

Comprehension combines explicit information, textual structure, logical inference, and evaluation of the writer’s choices; every interpretation should remain anchored in evidence.

A. identifying main idea

Identifying the main idea means determining the central claim or controlling point that unifies the important details.

• Topic versus main idea: “Air pollution” is a topic; “Air pollution requires coordinated transport and industrial reforms” is a complete main idea.
• Location: The main idea may appear in a title, thesis statement, topic sentence, conclusion, or repeated pattern rather than in one exact sentence.
• Supporting details: Statistics, examples, explanations, and quotations develop the central point. Data on asthma rates may support an argument about pollution’s health effects.
• Selection test: A valid main idea should cover most major details without becoming too broad. “Pollution is bad” is less precise than the passage’s supported claim.
• Construction method: Combine the repeated subject with what the writer says about it: topic + controlling claim = main idea.

B. inference-based

Inference-based comprehension reaches an unstated conclusion by combining textual evidence with reasonable background knowledge.

• Evidence requirement: In “Leah entered carrying a dripping umbrella and removed her wet coat,” the supported inference is that it is raining or has recently rained.
• Logical process: Identify clues, connect them, and choose the conclusion that explains all of them with the fewest unsupported assumptions.
• Types of inference:
  • Cause: Why an event occurred.
  • Attitude: How a person or writer feels.
  • Prediction: What is likely to happen next.
  • Reference: What a pronoun or phrase points to.
• Boundary: An inference is not a guess. The wet umbrella supports rain, but it does not establish the exact temperature or time.
• Qualification: Use measured language—“suggests,” “implies,” or “probably”—when the evidence permits more than one interpretation.

C. fact-based

Fact-based comprehension retrieves information directly and accurately stated in the text.

• Explicit evidence: If a passage states, “The museum opened in 1998,” then both the event and date are directly verifiable within the passage.
• Question signals: Prompts beginning with who, what, when, where, how many, or according to the text often target literal information.
• Retrieval method: Extract keywords, scan for them or their synonyms, and read the surrounding sentence to avoid selecting an unrelated match.
• Precision: Preserve units, qualifiers, and scope. “Nearly 40 percent” should not be reported as “exactly 40 percent.”
• Fact–opinion distinction: “Sales fell by 12 percent” is testable; “The campaign was disappointing” is an evaluation unless supported by stated criteria.

D. author's purpose and tone

The author’s purpose is the intended effect of the text, while tone is the attitude conveyed through language and presentation.

• Common purposes: A writer may inform through a report, persuade through an editorial, instruct through a manual, entertain through a narrative, or criticize through commentary.
• Tone evidence: Diction, imagery, punctuation, sentence structure, and selected details create tones such as optimistic, skeptical, urgent, neutral, or humorous.
• Concrete contrast:
  • “The policy produced mixed results” sounds measured.
  • “The policy was a disastrous failure” sounds strongly critical.
• Purpose–tone relationship: A safety notice may use an urgent tone to instruct, while a scientific article generally uses cautious phrases such as “the findings indicate.”
• Avoiding overstatement: Tone labels should match the whole passage. One negative word does not necessarily make an otherwise balanced article hostile.
• Bias indicators: Loaded words, omitted counterarguments, unsupported generalizations, and selective evidence may reveal an attempt to influence readers.

E. read and recall

Read and recall is an active strategy in which readers process a manageable section, look away, and reconstruct its meaning from memory.

• Core sequence: Preview the section, read attentively, close or cover the text, recall the main idea and key details, and then check accuracy.
• Meaning over wording: Recall should reproduce the argument in the reader’s own language rather than memorize every sentence.
• Chunking: Divide a long text by paragraph, heading, or idea unit. After a paragraph on photosynthesis, recall its inputs, process, and outputs.
• Retrieval cues: Headings, keywords, diagrams, and brief prompts help organize memory without replacing active recall.
• Accuracy check: Compare the recalled account with the text, restoring omitted qualifiers, dates, relationships, or examples.
• Comprehension benefit: Failure to recall a section exposes weak understanding immediately, allowing focused rereading instead of repeated passive reading.
