Step Ⅰ Lead-in
T: Do you remember in Unit 6 we have learned a horror film called “Murder in a Country House”?
Ask: Can you tell me the main idea of this film?
( A doctor is found dead in his house. People don’t know whether he was killed or he killed himself. )
T: Good. The doctor in this film is a victim. If he was killed by someone, that is a murder. And the person who killed the doctor is the murderer. The murderer killed the man, and he broke the law, so his act is a kind of crime, and he is the criminal. If we find a man, but we are not sure whether he is the murderer, we can call him a suspect.
Present the words.
Ask: If there is a murder, who will solve it? ( The police.)
T: Yes, a person, especially a police officer, whose job is to examine crimes and catch criminals is a detective(n.). So “ Murder in a Country House” is not only a horror film, but also a film about detective(adj.) stories.
Write down these words on the blackboard, and ask students to read together. Ask students to pay attention the word “detective”( n.&adj.)
