Getting temperature data separately by shp locations file

I want to getting temperature data separately location by shp file on the selected date. But with 'ee.Reducer' code, I can be getting to the last data on selected dates. How can I solve this problem? Thank you.

var imgreduce = lstCelciusEx.reduce(ee.Reducer.last());
var reduce = imgreduce.reduceRegions({
  collection: shp,
  reducer: ee.Reducer.mean(),
  scale: 1000 // the resolution of the MODIS dataset
});

print(reduce);
