Many chronicles show that man has known from ancient times that there is much water underground.Only recently has he begun to appreciate how much. Beneath most land areas of the world there is a zone where the pores (细孔) of rocks and sediments are completely made very wet with water. Hydrogist call this ground water, and the upper limit of the wet zone is called the water table. The water table may be right at the land surface, as in a marsh, or it may lie hundreds of feet below the land surface, as in some arid areas. Water in the unwet zone above the water table is called vadose water and includes the belt of soil moisture. Water in the intermediate part of this zone has passed through the soil and is dripping downward toward the water table.

Eating a diet high in processed food(加工食品)increases the risk of depression,research suggests.What's more,peopie who ate plenty of vegetables,fruit and fish actually had a lower risk of depression,the University College London team found.
Data on diet among 3,500 middle-aged civil servants(公务员)were compared with their emotional state five years later,a British journal reported.They split the participants into two types of diet--those who ate a diet largely based on whole food,which inc!udes lots of fruit, vegetables and fish,and those who ate a mainly processed food diet,such as sweetened desserts,fried food,processed meat,refined grains and high fat dairy products After accounting for factors such as gender,age,education,physical activity,smoking habits and chronic(慢性的) diseases,they found a significant difference in the future depression risk with the different diets.
Those who ate the most wholefood had a 26% lower risk of future depression than those who ate the least wholefood.By contrast,people with a diet high in processed food had a 58% higher risk of depression than those who ate a diet low in processed foods.
Study author Dr. Archana SinghManoux pointed out there was a chance the finding could be explained by fl lifestyle factor they had not accounted for.
There was a paper showing a Mediterranean diet was associated with a lower risk of depression,but the problem with that is if you live in Britain,the likelihood(可能性)of you eating a Mediterranean diet is not very high.
Dr.Andrew McCulloeh,chief executive of the Mental Health Foundation,said,this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health.
He added people's diets were becoming increasingly unhealthy.The UK population is consuming less nutritious,fresh produce and more saturated(含饱和脂肪酸的)fats and sugars.

Most people feel lonely sometimes, but it usually lasts only a few minutes or a few hours.This kind of loneliness is not serious.In fact, it is quite normal.For some people, though, loneliness can last for years.Now researchers say there are three different kinds of loneliness.
The first kind of loneliness is temporary.This is the most common type.It usually disappears quickly and does not need any special attention.
The second kind, situational loneliness, is a natural result of a certain situation, for example, a family problem, the death of a loved one, or moving to a new place.Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year.
The third kind of loneliness is the most severe.Unlike the second type, chronic (长期的) loneliness usually lasts more than two years and has no specific cause.People who experience habitual loneliness have problems socializing and being close to others.Unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition.
Psychologists agree that one important factor in loneliness is a person's social contacts, such as friends, family members, co-workers, etc.We depend on various people for different reasons.For instance, our families give us emotional support, our parents and teachers give us guidance, and our friends share interests and activities.However, psychologists have found that, though lonely people have many social contacts, they sometimes feel they should have more.They question then" own popularity.
Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness such as heart disease.While temporary and situational loneliness can be a normal and healthy part of life, chronic loneliness can be a very sad and sometimes dangerous condition.
