How to create target for makefile

 Hello:
   g++ Hello.cc dep.o -o Hello

 dep.o: dep.cc dep.h
        g++ -c dep.cc

I am trying out this makefile,but I want the target to be "make Hello". How should I modify my makefile? It work when I typed "make".

You need to add all the dependencies, recursively:

Hello: Hello.cc dep.o
        g++ -o $@ $+

dep.o: dep.cc dep.h
        g++ -c -o $@ $<

It would probably be better to add a separate compilation stage for Hello.o, but I'll stick with the format prescribed by the question. You should probably also add $(CXXFLAGS) and $(LDFLAGS) to the compilation and link stages, respectively, and replace g++ by $(CXX).
