Wanted: Private Chinese Tutor
My husband, two children, and I need a Chinese teacher because we are moving to Hong Kong next summer. The teacher must come for one hour on Monday, Wednesday, and Thursday evenings. We have some background in Chinese vocabulary and grammar, so we need to focus our classes on writing and conversation. We are willing to pay $20 an hour to the right person. Email Deb at chinafan@mailnet.com.

Question 4: Who wrote the advertisement?

Question 8 through 10 refer to the following chart.
Name    Height    Weight
John     178 cm    65 kg
Andy    175 cm    67 kg
Scott     181 cm    9 kg
Bill        79 cm      77 kg

John and his three friends decided to join the army. When they went to the army office, the army doctor began checking their height and weight. John was a bit embarrassed because he was thin and weighed only 65 kg. Andy was also embarrassed because he was the shortest. After the doctor’s check up, the boys began training.

Question 8: Who checked their height?
