Question: Article: Annual holidays have become a luxury and are no longer a staple of family life, according to government research. A getaway of a week or more is no longer considered essential by many families and is often beyond their reach, said the analysis of what parents and children say they really need. Fashionable clothes for the children, expensive birthday parties and lots of toys are also on the list of luxuries families don't have to have. Instead, recession -hit parents are thinking of the future, and the things they want for their children centre around learning to behave properly, good education and good health. Their picture of what a family ought to have includes a space to eat together away from the television, plenty of fruit and vegetables, and bicycles so children can get exercise. The breakdown of necessities and luxuries was prepared by researchers from the Department for Work and Pensions(DWP) who were trying to establish an up-to-date picture of what parents say they really need. Their findings show how families have scaled down their expectations in the face of economic difficulties -- how parents are now concentrating their attention and money firmly on the long-term interests of their children. Many believe that while it is vital for a family to do things together, day trips or weekend breaks are enough. Spending on furniture or decorating the house was also considered luxurious, unless the state of the home was so bad it became difficult to invite visitors in. Instead, researchers said: A family home should have an area where the family can eat together, not on their laps in front of a television. Families should be able to go on outings, overnight trips and possibly short holiday: the fact of being able to share these experiences is more important than the precise activity and its cost.
Answer: day trips or weekend breaks are enough for families to share experiences

Answer: In the opinion of most parents, _ .

Question: Article: Humans are well-equipped for life on Earth. But in space, it is different. Low or _ changes how the blood flows and causes motion sickness, muscle loss and tiredness. Weightlessness can also cause bone loss. But scientists are experimenting with little worms to better understand how space travel affects astronauts. The millimeter-long worm is called C. elegans. The see-through worm is often used in medical studies because its life is only about two weeks long. Seventy percent of its DNA is the same as human DNA. Sabanayagam is a scientist, who built a micro-gravity simulator to test how C. elegans would perform in the actual zero gravity of space. Scientists put the worms into the simiulator full of water. After a week they take out the worms. They look for changes in the worms' epigenome,which are chemical markers that tell the DNA in the cells how to perform. The epigenome can be changed by the environment. And those changes pass from one generation of worms to the next. "When the worms are in a liquid environment, some epigenomic marks remain even when we take the animal out of the liquid environment and put it back into normal ground conditions. So its offspring keeps this epigenomic memory of the parents' liquid environment or microgravity environment." The information the scientists have gathered suggests that the epigenomic marks appear during the early part of a worm's life. Mr. Sabanayagam says he thinks scientists can find genes in the human similar to those in the worms that responded to microgravity and scientists could possibly observe those genes closely when astronauts travel in space. Sabanayagam expects C. elegans to visit the International Space Station within two years. He says he hopes information gathered from the worm studies can be used to develop simple, low-cost and quick tests to measure an astronaut's health.
Answer: has a short life period

Answer: From the passage we can know C. elegans _ .

Question: Article: Homeschooling is a popular alternative to send your children to a public or private school. It seems to be especially popular with stayathome parents who would rather teach their children themselves in the privacy of their own homes. In order to homeschool your children,you will need to know the basics of how to do this,and like everything,there are steps you will need to follow. Homeschooling is legal in all fifty states. The first step is to check with your state's Board of Education to find out what the legal requirements are and what you will need to do in order to _ them. Next,you will need to determine whether or not you want your children to follow a structured curriculum. Most parents use this system to ensure that their children will study every subject that a child who goes to a private or public school would. Homeschooling can not only provide your children with the essential learning of the basic subjects of reading,writing,and arithmetic,but it can also help your children to master muchneeded life skills. These skills can range from learning how to do the cleaning to balancing his or her own checkbook. They are skills that your child will need to know so that he or she can take care of themselves later on in life. One last point about homeschooling:The question of interaction and socialization is most always brought up in the question on whether or not a child should be homeschooled. Public schooling is automatically thought to be a good place for a child to learn how to get along with his or her peers. While some social skills probably can be learned in this type of environment,peer pressure is always a constant concern for parents. Fortunately,parents who homeschool can teach their children moral values as well as the right way to get along with other people.
