Due Attention Should Be Given To Spelling

Correct spelling is a basic skill in English study. However, nowadays many students do not pay much attention to it.

They have their own reasons for misspelling. First of all, they like an easy way of studying, which causes some omissions and changes in spelling. Second, the teachers might not be very strict in students’ spelling. In China, teachers seem to be more concerned with grammar and vocabulary but not spelling.

To change this situation, in my opinion, the teachers and the students should work together. On one and, the teachers should give more attention to students’ spelling, asking the students to be conscious of the importance of correct spelling from the very beginning of their English study. On the other hand, the students themselves are supposed to be aware that correct spelling is a must in English study.

To sum up, correct spelling is so important that both students and the teachers should spare no efforts to achieve correct spelling.

ver？ If you have, don’t feel alone! It’s a very common, natural wish that has a long history.Spanish explorers of the sixteenth century even tried to find a fountain of youth in what is now the state of Florida.The water the this legendary fountain, which no one has yet found, was believed to restore youth and good health to those who drank it.

Biologists today don’t expect that anyone will find a magical fountain of youth.Growing older is a natural part of the life cycle that can’t be reversed.As human beings grow older, organs such as the heart and lungs may stop functioning properly.Sight and hearing may become weak.And the human body becomes more likely to come down with serious illnesses from which it cannot recover.

Considered together, changes that bring about the decline of an organism are called aging.Because of aging, many biologists believe that there may be a maximum age limit to which even the healthiest organisms can live.For human beings, this maximum age limit is about 110 years.

Perhaps the most important thing that you can learn from your study of human biology is that you have a lot of control over the aging process in your own life.In fact, within our control are many physical and mental factors that have much to do with aging.For example, each of us, as recent research indicates, can do many things to help prevent heart and vessel disease, which causes half the death each year in the United States.We can avoid eating a lot of fatty meat.Eating too much of these types of animal fats can lead to the clogging and hardening of blood vessels.We can cut back on smoking and hopefully quit entirely.We can limit the amount of alcohol we drink and the amount of sugar we eat.We can exercise regularly and strengthen the heart and other organs.And we can remember to take time out each day for ourselves, time just relax.Exercise, recreation and relaxation all reduce stress – inner tension that is hard on all body organs.

One final thing we can do is to try to keep aware of advances made in health education.Information is often available free of charge from health clinics or schools.
