题目内容
Many people travel to different places in the world by air. Usually it takes a long time, perhaps half a day, for passengers to stay in the plan. So airlines（航空公司）offer passengers food. But it is common that they feel bad about food taste. Do you agree?
To solve this problem, airlines try hard to improve their food. They would like to do so because they don’t want to lose customers.
However, according to scientific research, part of the reason why plane food tastes bad is that at high altitude（海拔）we can not taste things as well as we do on the ground. Also scientists have found that our noses become very dry even before a plane takes off. As the plane moves up, the change in air pressure（气压）reduces one third of the sensibility（感觉）of our taste buds（味蕾）. So our taste buds become senseless. The sad face, however, is that our noses don’t know it.
All of these help explain why food on the plane tastes so bad. They also help explain why airlines choose to offer passengers salty and spicy（辛辣的）food. Without doing so, the food would be tasteless.
Now there are many researches on this. According to one of them, some volunteers are asked to lie with their feet higher than their heads for weeks. And scientists write down their feelings about food taste.
Though scientists try their best, it is not as easy as they thought. Because they can’t deal with the special environment successfully, such as the change in air pressure, making food taste good is still hard for them.

The concept of homeschooling is not a new one. Homeschooling means educating children at home instead of sending them to public or private schools. Nowadays, homeschooling has become popular in the USA for a lot of reasons. One of them is poor quality of education in public schools and it’s also because of the high cost in private schools. Some parents believe that because they know their child’s strengths and weaknesses, they can teach him or her better. Some parents prefer homeschooling so as to prevent their children from getting into bad company. There is another group of people who choose to educate their children at home because they want them to learn their religious beliefs. They also think that homeschooling would help in development of strong family bonds (家庭纽带).
However, there are some negative influences of homeschooling on students as well as parents.
Homeschooling is a full-time job and not fit for parents who have their own careers. It takes a lot of time for parents’ side to make homeschooling a success. Other family members’ responsibilities may also be affected. They may give their full attention to the needs of their children. Besides, a parent may have high educational qualifications, but that does not make him or her a good teacher. Teaching is an art, which requires the ability to understand the needs of the children. It may be difficult for the parents to explain the concepts to their children.
In today’s world, competition is seen in every field, and school prepares children to face these competitions. However, homeschooling does not give the children a chance to compare with other kids. They will also not be aware of where they stand in educational position among their classmates. This may affect their lives. Education is not the only thing that the children need to become successful human beings. It is necessary that they learn to communicate in the society, and public school provides them with such an environment, where they meet many people. Schools also provide children with a chance to take part in different activities to improve their overall development.
It is true that it has many advantages, but one must get to know that school teaches children skills to survive.
