Nowadays parents and their children are spending less and less time communicating with each other.1. It is reported that American parents today spend about 40 percent less time with their children than parents did a generation ago. To keep your family time creative and enjoyable, below is a list of helpful family time tips.
（1）Eat together & listen to each other
Most children today don’t know the meaning of a family dinnertime. Yet the communication and unity built during this time is necessary to a healthy family life. Sharing a meal together allows parents and their children the opportunity to talk about each other’s lives.2..
（2） Read often
It’s important for parents to read to their children. The latest research shows that reading to your children develops an interest in knowledge and contributes to language development. It also increases their concentration on things and helps them become more curious.3. After reading, ask questions about what the books are about.
（3）Start a hobby or project
Choose a fun activity that your children are interested in. Activities like cooking, fishing or biking can be their great hobbies.4.. Once a child learns a new skill, let him or her take the lead under your direction.
（4）Plan a family outing
5.. Jump into the family car and go for a drive. Prepare a picnic lunch and visit a local park. Take time to play or ride a bike. A slow and relaxing walk in the woods will help parents communicate with their children better. Also, a visit to the zoo or museum will inspire enthusiasm in a child and lead to long discussions.
A. It is very important for children to exercise.
B. They can open the door to exciting family time.
C. Sometimes getting out of the house is important.
D. Look for books that your children would enjoy reading.
E. New technology has made video games more popular with children.
F. This is also a time for parents to listen and give advice to their children.
G. As a result, many children are getting less love than their parents once got.
DNA（Deoxyribonucleic acid）is one of the most important discoveries in science. DNA is the plan for the human being，as a blueprint is the plan for building. DNA makes a person look the way he does. A person’s DNA comes from a mixing of his parents’ DNA. That’s why a child looks like his parents. But，besides controlling things such as height and hair color，DNA can also give people diseases. Scientists are now studying DNA to cure（治疗） diseases.
In the seventies, scientists developed a process called recombinant (重新组合) or RDNA. Although it sounds difficult to understand，RDNA simply means taking DNA from one animal or plant and putting it into another. By doing so，scientists can create new beings. In doing so，scientists can better understand DNA, especially what parts of DNA do. After they understand DNA，scientists can begin to cure diseases. Often，the new being created itself will be the cure.
Besides curing diseases，RDNA research can also do other things. For example, scientists in Japan have already created “super-trees”. Trees help humans，because they take CO2, which poisons humans, from the air and turns it into oxygen, which lets humans breathe. “Super-trees” do this too，but do it much faster. As things such as cars and factories have already put much CO2 in the area，“super-trees” are badly needed.
Unfortunately，there is serious danger in RDNA research. Scientists want to create animals to cure old diseases，but these new animals may also create new diseases. It will be a serious problem if the animals escape from the science laboratory and into nature. As these animals are not natural, they may let loose many new powerful diseases.
As a result，RDNA research will create many solutions（解决方案），but it will also
create many problems.
