Section 1: Grammar – Verbs (Definition, Identification, & Action Verbs)

Every complete sentence needs a engine to make it run. In English, that engine is the verb. Without a verb, you only have a collection of naming words and descriptions, but no movement or life.

1. What is a Verb?

A verb is a word that expresses an action, an occurrence, or a state of being.

• Action: What is someone or something doing? (e.g., run, sweep, pollute)

• Occurrence: What is happening? (e.g., decompose, happen, become)

• State of Being: What is the condition or existence of something? (e.g., is, are, seems)

2. Spotting the Action: Identifying Action Verbs

Action verbs specifically describe physical or mental activities. If you can physically do it, or if your mind actively processes it, it is an action verb.

Identification Tip: To spot a verb in a sentence, look for the word that answers the question: “What is the subject doing?”

• The students recycle plastic bottles every Friday. (What do they do? They recycle.)

• The health inspector visited our community yesterday. (What did he do? He visited.)

• Dirty water breeds mosquitoes. (What does the water do? It breeds.)

Section 2: Vocabulary – Environment and Sanitation

Sanitation and environmental preservation rely heavily on specific vocabulary. Mastering these words helps us discuss issues like pollution, public health, and ecological balance clearly.

Word	Definition	Example Sentence
Biodegradable	Capable of being decomposed by bacteria or other living organisms.	Food scraps are biodegradable and make excellent compost.
Contaminate	To make something impure or dirty by exposing it to poisonous or polluting substances.	Chemical waste will contaminate the local river if left unchecked.
Sanitation	Conditions relating to public health, especially the provision of clean drinking water and adequate sewage disposal.	Improving community sanitation reduces the spread of diseases like cholera.
Effluent	Liquid waste or sewage discharged into a river or the sea.	The factory was penalized for dumping untreated effluent into the stream.
Ecosystem	A biological community of interacting organisms and their physical environment.	Plastic pollution disrupts the marine ecosystem.

Environmental Action Context

When we combine our grammar focus with our vocabulary, we see action verbs driving environmental change:

• We must preserve our forests.

• Do not litter the highways.

• The community cleared the blocked drainage system.

Section 3: Speech – Pure Vowels (/ɪ/ vs. /i:/)

English pronunciation can be tricky because the same letters often make different sounds. Today we focus on two monophthongs (pure vowels)—vowels where the sound remains constant and does not glide into another sound.

The primary difference between these two sounds is vowel length and tension in the mouth.

 

1. The Short Vowel Sound /ɪ/

• How to say it: Your tongue is relaxed, and your mouth is only slightly open. It is a short, crisp sound.

• Common Spelling Patterns: Usually represented by the letter ‘i’.

• Examples: sit, bin, pit, fit, lid, ship

2. The Long Vowel Sound /i:/

• How to say it: This is a long sound. Your lips stretch out to the sides almost like you are smiling, and the muscles in your mouth are tense.

• Common Spelling Patterns: Often represented by ‘ee’, ‘ea’, ‘ie’, or ‘e’.

• Examples: seat, been, peat, feet, lead, sheep

Side-by-Side Comparison (Minimal Pairs)

Minimal pairs are pairs of words that differ by only one phoneme (sound). Practicing these helps train your ear and tongue to notice the distinction.

Short /ɪ/ (Relaxed)	Long /i:/ (Tense/Smiling)
Sit (/sɪt/)	Seat (/si:t/)
Bin (/bɪn/)	Been (/bi:nd/)
Ship (/ʃɪp/)	Sheep (/ʃi:p/)
Fit (/fɪt/)	Feet (/fi:t/)
Grin (/ɡrɪn/)	Green (/ɡri:n/)

Class Work & Assessment

Exercise A: Identify the Verb
