不好意思，来拍砖了

It's a very good reading, especially with such a short preparation, although there are some places which you seem habitually read that way and need to be noted:

1. /r/ is not clear in words "PROGRAM";
2. "IF" is /if/ not /i:f/;
Others to note:
1. situation / -ch- /;
2. told you / -dg- /;
