I am sure whether I can find the information of the load history
information some where in a log file.
Just like what the command "top" tells.
This is because my machine often freeze due to some unknown reasons. I
just want to check if there's a coincide with the high load. Thanks in
advance!

There are many approaches to get what you want. The simplest I can
think of is:
top -b -d 300 >> /path/to/topfile &
This command will keep adding the output of top command to the
specified file after every 300 seconds (not the very efficient
approach, of course)

alternatively:
cat /proc/loadavg
uptime <-- includes a timestamp.
