I have heard about three-D printing that is used for printing parts of the body to replace those that are lost or injured beyond repair. For example, a leg or ear can be three-D printed to the precise measurements of the patient. Precision medicine is another medical advance I know about. This health care approach takes into consideration patients' genes, lifestyles and environments to find unique risk factors and develop personalized therapies. Both of these medical advances are incredible because they are tailor-made and therefore provide accurate and effective treatments for the patients. • What do you know about genes? I know that genes are found in the cells of all living things. Genes are very small and carry the DNA information which decides what we become. All living organisms have different genes; therefore, no two individuals are 100% alike, even though there may be similarities. At the DNA level, not even identical twins are the same. Scientists are studying genes to help prevent health problems from being passed on from parents to their children. They are also trying to find ways to treat diseases that are caused by bad genes. 学生活动：略读文章，完成活动A1。 Para.2:
