Abstract: Internet media is developing rapidly， which will come into the ubiquitous， omnipresent and omnipotent “ubiquitous network” in the future and push human society into a new “Ubiquitous Network Era”. The ubiquitous network will have a deep and fundamental influence on the “subject” so that it may build up a “new subject” without “stabilization”， i.e.， the combination of cyborg， immersive person and post human. The ethical risks of this new era can be attributed to the “new subject” built up by the ubiquitous network. Because the sacred source of ethical construction is composed of the family and its members， the family is the natural starting point of ethical construction while its members are the starting point of the beginning. The “new subject” under the ubiquitous network will blur the moral characteristics of men and women and change the ethical role of offspring. As a result， it will profoundly shake the sacred root of ethical construction and transform the generative path of ethical construction. To deal with the ethical risks in the “Ubiquitous Network Era” is to learn to think ethically， putting forward a reliable ethical warning in time and making a reasonable ethical plan in advance.

Key words: ubiquitous network, subject, family, member, ethical risk
