Lijian,

If I understand you correctly, you have georeferenced GeoTIFF and
you have a Shapefile *without* any referencing.
Now, you have read SRS details from GeoTIFF - it is WGS84 with
EPSG code 4326 - and you want to *assign* the same
one to your Shapefile.

If that's what you want to do, then the command should look as follows:

ogr2ogr -a_srs EPSG:4326 out.shp point.shp

where -a_srs means you want to *assign* SRS to output Shapefile (out.shp).

Here is the code, in the GeoTIFF details:

AUTHORITY["EPSG","4326"]],

Cheers
