It seems i delete the libboost_thread.so.1.66.0, the zypper cann’t run .
how to resolve this problem. which command should i use to install it.
zypper: error while loading shared libraries: libboost_thread.so.1.66.0: cannot open shared object file: No such file or directory
On my (15.4) system it is: /usr/lib64/libboost_thread.so.1.66.0.
Thus grab it from your backup.
There is also a bugreport:
https://bugzilla.opensuse.org/show_bug.cgi?id=1216876
You could try to create a symbolic link sudo ln -s /usr/lib64/boost-legacy/libboost_thread.so.1.66.0 /usr/lib64/libboost_thread.so.1.66.0
When it is a (known) bug, then
is a red herring?
Seems that the OP is not really aware of what he is doing on his system. 
When you do a zypper up and afterwards the system complains about a missing library, new users could think they deleted something.
Here unfortunately the library got a new installation path after update, so that zypper complains that it can‘t find the library anymore.
The bug was reported last night so it may take some time for a fix. I would try the way with symbolic linking of all libraries that are located in /usr/lib64/boost-legacy/ back to /usr/lib64/
