(Teacher shows the following on the screen.) rewrite,unhappy,disappear,impossible,invisible,non-smoker,supermarket,worker,illness,movement,useful,action,cooperate,cloudy,musical T:What do the words mean?Explain how you guess them.Who’d like to do the first one? S8:“Rewrite” means “write again”,because the prefix “re-” expresses “again”.Am I right? T:Right.Very good. S9:“Unhappy”“disappear” “impossible” “invisible” and “non-smoker” mean in turn “not happy” “not appear” “not possible” “not visible” and “people who don’t smoke”.Because the prefixes “un-” “dis-” “im-” “in-” and “non-” all mean “not” and form the negative meanings of them. T:A good job!Let’s go on. S10:“Supermarket” is made up of two parts:“super” and “market”.Market is a place where all kinds of things are sold,and “super” means “more than usual”.So “supermarket” means “超市” in Chinese. T:You’re right.Can you give some other examples? S10:Yes.For example,superman,superstar. T:Very good.Now,who knows the meaning of the word “cooperate”? S11:“Cooperate” is to say “work together”.Because “co-” means “together” or “with”. T:Do you agree with him/her? Ss:Yes. T:That’s right.Do you know the meanings of the rest words? Ss:Yes. (Students begin to say the meanings of them together.Then teacher asks one of them to explain them.) T:Wang Lin,tell me how you guess them. (责任编辑：admin) |
