Practice for 8/30 and 9/23 她没有告诉我他的名字（casual conversation）她没有告诉我那个先生的名字（formal written）
（“她”and“他” have the same pronunciation，If you have the same pronunciation of two different meaning words in a short sentence，you can do it in casual conversation，but if you want to be more polite，you’d better change the word）。
if you want to underline time，you cant use phone now，you can use “时”
if you want to underline the rule，you cant use phone at work，you can use“中”
“用手机”means we use it in order to accomplish something，like taking on the phone，searching information。
“看手机”means we just habitual check if we get some new information on Facebook or instagram，the time is usually short，but happens very frequently。
“玩手机”means we play games or watch videos，or skim Tiktok。
hope these will hlep you，but dont care about too much。in the daily conversation，we can understand what you what to say。
She didn’t tell me his name.
You shouldn’t use cell phones at work. Thanks!
