A. Unfortunately, there aren’t nearly enough trained genetics counselors to handle the coming upsurge in demand for this type of information.
B. Adults cannot do much to alter their biological lot, but what if parents could examine their unborn child’s genome?
C. Cancer has become the first killer these years. That’s why people tend to take overtreatment with the knowledge of family history.
D. Another fear is that a customer without discussing with genetics counselor can receive information via the Internet about a multifold greater risk of breast cancer.
AB. Another problem arises whether it is moral to chose to stop pregnancy because of the genome problem.
AC. Attitudes toward child rearing might change along with the new technology.
1) In a few years you will be able to order a transcript of your entire genetic code for less than $1,000. ____67____Two different university laboratories have developed test that will reveal the entirety of a baby’s genetic code using just a blood sample from the mother plus a drop of saliva(唾液)from the father.
2) Prenatal(出生前的) whole-genome sequencing will provide volumes of information beyond the currently available tests exclusively for genetic disorders such as Down’s syndrome or Tay-Saches disease. The three billion units of code furnished in the new tests will also dwarf(使……相形见的) the relative trickle(零散)of information provided by consumer gene-testing services such as 23andMe, which currently look only at perhaps about one million locations in the genome.
3)____68____Without careful panning, the new prenatal genetics might rob a child of the chance to make decisions best left until adulthood---whether or not to learn, for instance, if a mutation(突变)predicts the inevitability of Huntington’s disease 20 years hence.
4)_____69_____. Similar laissez0faire(放住)action to prenatal whole-genome testing could portend(预示)tragedy.
5)Ultimately certain agency will need to develop a comprehensive policy on prenatal whole genome testing. Bioethics scholars wrote an analysis last summer that calls on the medical community to develop a guide to the most relevant genomic data for future parents. ___70___Without access to a much higher level of refined expertise, the secrets of our offspring’s genetic code will continue to remain an unnerving cipher---or worse.

Some people believe that greed and selfishness has become the basis of modern society, and we should return to the old traditions of family and community then we will have a better life. To what extent do you agree or disagree with the above opinion?
In this fast-paced world, many values are undergoing major changes. While people traditionally prioritize caring, sharing and generosity in life and work, modern people seem to be more self-absorbed and self-concerned.
Modern people act selfishly to survive the harsh competition of life. They say that it is a jungle out there. To survive, you have to fight with whatever means that come handy. Obviously greedy and selfishness go perfectly well with such ideas. In a company, employees do everything they can to get better pay and higher position, even at the cost of colleagues. We are in any way advocating any selfish conduct. It is just that people are pressured to act in a certain way due to outside influences.
In spite of common practice, it is hard to conclude that modern society is built on greed and selfishness, both of which are not newly invented vocabulary. In ancient times people also did greedy and selfish things though such behaviors were more condemned then. But we can not ignore the fact that people in the past lived a relatively more isolated life and faced less pressure compared with their modern counterparts.
Are we happier to share with others and be generous to them? There is no fixed answer either. Some people take great pleasure helping and giving to others while others feel happy doing the opposite. But I personally think that people should not be too selfish. Caring for others can actually encourage the development of a mutually beneficial relationship.
In conclusion, modern people appear to be more self-centered than those in the past due to strong outside pressure. However, we should encourage people to know the importance of being caring and generous and to build a mutually beneficial relationship with others.
