Can we "design" a baby the way we design a handbag？It may sound crazy，but the technology for a "designer baby" is actually possible.But this problem has also caused a lot of debates （爭(zhēng)論）.
A "designer baby" refers to the research that allows scientists to make changes to unborn babies' DNA.The changes to the DNA and genes （基因）are made in the hopes that babies will less likely be born with certain serious illnesses.The idea that we could stop children from being born with such illnesses became very popular，so during the 21st century，research progressed very quickly.
However，people learned that it was not only illnesses that we could change，but also a baby's gender and physical appearance.A well-known case on the use of genetic engineering happened in 1996.An American couple，Monique and Scott Collins，decided to use a doctor's research to help them choose the gender of their next baby.They wanted to have a baby girl.Their story became famous and caused debates on how much doctors can do.For example，you could control babies' eye color，hair color and even things like height.
People think that it is not right to design our babies the way we would design a bag，but the research is also helpful in the medical field.One example of this is that Dr Adrian Thrasher of University College London was able to save a 1-year-old child from leukemia（白血病）.

2．One teacher praises a student by saying "You're so smart!" Another teacher says "You must have worked really hard at this!" Which student does better in school？Studies show that students who hear the words of the second teacher will do better.Those students are learning that their effort is important.
Psychologists（心理學(xué)家）looked at what students did after they were given different types of praise.Some students were told that they were good at a task.They didn't try very hard the next time.Other students were told that they had worked hard at a task.They worked even harder the next time.The first group of students was learning that they had a set amount of skill.They didn't think they could do any better.This is called a fixed mindset（思維模式）.The second group was learning that they could do better if they kept trying.This is called a growth mindset.People who have a growth mindset believe that the brain can grow；people can do better and learn new skills.If they work hard，they can be successful.
How can teachers and parents help students succeed？They can focus mainly on effort and not simply on ability.When students succeed，teachers and parents should praise the actual work rather than intelligence（智力）or talent.When students fail，they should be told how they can do better.Teachers，parents and students need to value effort，not intelligence.
