8A Unit 7 Grammar (教学设计)
I. Teaching Objectives
A. Knowledge Objectives
1. Students will master two grammar points:
· Verbs that take two objects (direct and indirect objects) and how to reorder them using “to” or “for”; verbs with object complements.
· The correct usage of conjunctions “and”, “but”, “or”, and “so” to connect ideas.
2. Students will be able to identify and apply these grammar structures in sentences related to ecosystems.
B. Ability Objectives
1. Improve students’ ability to analyze sentence structures (S + V + IO + DO; S + V + DO + OC) through practical exercises.
2. Enhance students’ skills in using conjunctions to create coherent sentences about ecosystems, promoting logical thinking in English.
C. Emotional Objectives
1. Strengthen students’ connection between grammar learning and the theme of “The Natural World”, fostering environmental awareness while practicing grammar.
2. Boost students’ confidence in grammar application through interactive and contextualized practice.
II. Teaching Key & Difficult Points
A. Key Points
1. For Verbs & Sentence Structures:
· Recognize verbs that take two objects and reorder IO and DO with “to/for”.
· Identify object complements and use the S + V + DO + OC structure.
2. For Conjunctions:
· Use “and” (similar ideas), “but” (contrasting ideas), “or” (possibilities/negatives), “so” (results) correctly in ecosystem - related contexts.
B. Difficult Points
1. Accurately reorder indirect and direct objects with “to/for” without changing sentence meaning.
2. Distinguish between using “or” in positive (possibility) vs. negative (joining negatives) sentences.
3. Apply complex grammar structures (e.g., with adverbials) naturally in writing/speaking about ecosystems.
III. Teaching Procedures
A. Lead - in: Ecosystem Context Activation (5 minutes)
1. Show a short video clip about different ecosystems (forests, oceans, deserts). Ask: “What did you see? Why are these ecosystems important?”
2. Connect to grammar: “Today, we’ll learn grammar to better describe and talk about these amazing natural ecosystems!”
B. Grammar 1: Verbs & Sentence Structures (15 minutes)
1. Explanation (Visual + Examples)
· Two - Object Verbs:
· Present the structure S + V + IO + DO (e.g., “The sun gives ocean animals light and heat”). Explain IO (indirect, “ocean animals”) and DO (direct, “light and heat”).
· Show how to reorder with “to/for” (e.g., “The sun gives light and heat to ocean animals”). List verbs (e.g., give, build) and their prepositions (“to” verbs: give, hand; “for” verbs: build, make).
· Object Complements:
· Introduce S + V + DO + OC (e.g., “The mother bird keeps the eggs safe”). Explain OC (“safe”) adds info about DO. Use examples from the text (e.g., “They call the ocean the heart of the earth”).
2. Practice: Amy’s Desert Writing (Task A)
· Have students read Amy’s writing about deserts. Underline sentences and identify structures (S + V + IO + DO or S + V + DO + OC).
· Check answers together, explaining how each structure works (e.g., “Many desert plants give animals water” → S + V + IO + DO).
C. Grammar 2: Using and, but, or and so (15 minutes)
1. Explanation (Contextualized Examples)
· Conjunctions Introduction:
· Use ecosystem - related sentences to explain each conjunction:
1. and: “Rainforests are hot, and they get a lot of rain” (similar ideas).
1. but: “Deserts are dry, but some plants keep water in leaves” (contrasting).
1. or: “Birds can live in forests or wetlands” (possibility); “The deep ocean isn’t warm, bright or noisy” (negative joining).
1. so: “Deserts are dry, so plants store water” (result).
2. Practice: David’s Ecosystem Ideas (Task B)
· Students help David join ideas with conjunctions. Do the first one together (e.g., “Grasslands can be hot, so animals sit under the shade of trees”).
· Let students complete the rest independently, then check as a class. Discuss why each conjunction is chosen (e.g., “Wetlands can have salt water or fresh water” → possibility with or).
D. Integrated Practice: Ecosystem Sentence Building (8 minutes)
1. Mix both grammar points: Ask students to write 3 sentences about ecosystems, using either two - object verbs/object complements AND conjunctions.
· Example: “Forests take in CO₂ and produce oxygen, so they are called the ‘lungs of the earth’” (uses and, so, and could include S + V + DO + OC if adjusted).
2. Share sentences in pairs, then select a few to share with the class for feedback.
E. Summary (2 minutes)
1. Recap key grammar:
· Two - object verbs (reorder with “to/for”), object complements.
· Conjunctions: and (similar), but (different), or (possibility/negatives), so (result).
2. Emphasize: “These grammars help us describe ecosystems clearly and logically!”
F. Homework (5 minutes)
1. Write 5 sentences about your favorite ecosystem, using both grammar structures (two - object verbs/object complements + conjunctions).
2. Find 3 sentences from a science article about ecosystems and identify their grammar structures (focus on today’s points).
IV. Blackboard Design
A. Grammar 1: Verbs & Sentence Structures
· S + V + IO + DO
· Verbs + to: give, hand, lend... (e.g., “Plants give animals water → Plants give water to animals”)
· Verbs + for: build, make, prepare... (e.g., “We build homes for wildlife”)
· S + V + DO + OC
· OC describes DO (e.g., “Birds keep eggs safe”; “We call oceans the ‘heart’”)
B. Grammar 2: Conjunctions
Conjunction
Use
Ecosystem Example
and
Similar ideas
“Forests are green and full of life”
but
Contrasting ideas
“Deserts are dry, but have unique plants”
or
Possibility/Negatives
“Animals live in forests or wetlands”; “Oceans aren’t silent or still”
so
Result
“Wetlands clean water, so they help ecosystems”
This plan embeds grammar in the unit’s “natural world” theme, using contextual practice to make learning relevant and memorable. It balances explanation, guided practice, and creative application to master key structures.
