Dear Bob,
How’s it going This week we learned a story called The Old Oil Seller. I can’t wait to share it with you.
Long ago, there was an excellent archer named Chen Yaozi. He felt great about his archery skills. One day when he was practising, a lot of people praised him excitedly. But an old oil seller just smiled a little. So Chen went up and asked, “My archery is excellent, isn’t it ”
The oil seller said, “Nothing special. Just practice. (/You’re great only through much practice.)” (1′) Then he put a copper coin on the mouth of a gourd bottle. (1′) He poured the oil slowly (into the gourd) through the hole of the coin. (1′) “Amazingly, the coin did not get any oil.” (1′)
I totally agree with the old oil seller. I learnt that practice makes perfect. (2′) You see, I keep running every day, rain or shine. I run really well now and I’m happy I won the first in the school running competition. (2′)
What do you think Looking forward to your story and ideas. (1′)

解析　(1)光路如图所示
由折射率公式得n=
又有θ1=α=45°
θ2+C=
在O点发生全反射，则有sin C=
联立解得n=
(2)由上式可知sin C=
