高一必修一Unit 4第三課時教案
step 2 discovering the grammar rules(12 minutes)
1. translating the sentences above(pair work)
ask the students to translate the sentences above with the teacher’s help .
2. finding out the function (class work)
ask the students to focus on the underlined parts of each sentence, and pay attention to its structure function. help them draw a conclusion: an attributive clause gives more information about someone or something referred to in the main clause.
3. discovering the structure(pair work)
with teacher’s illustrations,students try to sum up the structures of attributive clause : sb.sth. + that/which/who/whose + other parts of the clause
antecedent + relative pronoun + other parts of the clause
【設計說明:本環節先通過讓學生接觸大量含有定語從句結構的語言材料,再通過學生自己觀察,發現,提取,加工及教師的適當引導,進而從中總結歸納出定語從句語法規則。這有利于學生探究學習和自主學習能力的提高。】
step 3 summing up the usage (10 minutes)
1. scanning (single work)
ask the students to scan the text and find out the attributives clauses.
a. but the million of people of the city, who thought little of these events, were asleep as usual that night.
b. a huge crack that was eight kilometres long and thirty metres wide cut across houses, roads and canals.
c. the number of people who were killed or injured reached more than 400,000.

e. the army organized teams to dig out those who were trapped and to bury the dead.
f. workers built shelters for survivors whose homes had been destroyed.
2.comparing & finding the rules (group work)
ask the students to compare the underlined sentences from the text and find the relative pronouns, then discuss in what cases those relative pronouns are used.
3.filling in blanks and translating (single work)
ask the students to complete and translate the sentences in exercise 2 on page 29 in the textbook.
4. explaining the usage of the relative pronouns
ask a few students to try to explain the usage of the relative pronouns with the sentences they found in the text. then teacher gives a summary.
【設計說明:本環節采用的“觀察—對比—分析—討論—歸納”的語法教學模式讓學生體驗探究定語從句中關系代詞的用法。】
