5. sharing and correcting
well done. now share your forms with your partner and tell me in the three forms: what are facts? what are opinions? li ming, do you want a try?
keys: what they heard, saw, did are facts. and what they believe are opinions.
6. reviewing
we often use some expressions to ask for opinions. what are they?
oh, yes. what do you think of …?
do you believe …?
how can you be sure of …?
how do you know that?
and we often use some expressions to give opinions. what are they? ok, tom, please. oh, yes. they are: i think… / i don’t think… i don’t agree that… / i suppose that…
7. discussing
please look at exercise 3, and discuss which person gave the best evidence. use the expressions above to help you. before we discuss, let’s deal with the following discussion:
a. what is the best evidence?
b. how can we know which eyewitness is most believable?
keys:
a. the best evidence is factual and is given by a person who is believable.
b. the most believable eyewitness is the one who has nothing to gain from telling a lie.
well done. let’s come to the discussion “which person gave the best evidence?”
keys fore reference:
jan hasek is less believable because he owns a little restaurant near the mine. if the search stopped, his business would suffer.
hans braun is also less believable because he is working for a company trying to find the ship which carried the treasures in the baltic sea.
of the three eyewitnesses, only anna petrov has no selfish reason for saying what she has said. in particular, she is not involved in any current effort to find the treasure. therefore she is the most believable.
8. reading and writing
sometimes we may fall into or face a moral choice. that is a moral dilemma. let’s read the letter on page 7 and see what’s johann’s choice and opinion. ok, finished? now answer the following questions:
a. what’s johann’s opinion about the amber room?
b. what’s his father’s opinion about the things found by him?
c. what happened to johann when she was a pupil?
keys:
a. johann thinks the people who find the amber room should keep it for them own.
b. his father thinks as johann does.
c. she found a little money and kept it to himself.
9. completing the letters a & b and then giving your own letters
