How man first learnt to invent words is unknown; in other words, the origin of language is

a mystery. All we really know is that man, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to stand for those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words.

The power of words, then lies in their association with the things they bring up before our minds. Words became filled with meanings for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increase.

Great writers are those who not only have great thoughts but also express these thoughts in words that appeal powerfully to our minds and emotions. We should therefore learn to choose our words carefully and use them exactly, or they will make our speech silly and impolite.

The origin of language is ______.

A．clearly explained in this passage

B．a matter that can not be or has not been explained or understood

C．a question that was difficult to answer

D．a problem already solved

第4题

Centuries ago, man discovered that removing moisture from food helps to preserve it, and t

hat the easiest way to do this is to expose the food to sun and wind.

All foods contain water--cabbage and other leaf vegetables contain as much as 93% water, potatoes and other root vegetables 80% , lean meat 75% and fish anything from 80% to 60% depending on how fatty it is. If this water is removed, the activity of the bacteria(细菌) which cause food to go bad is checked.

Nowadays most foods are dried mechanically. The conventional method of such dehydration(脱水) is to put food in chambers through which hoi air is blown at temperatures of about 110°C at entry to about 43°C at exit. This is the usual method for drying such things as vegetables, minced meat, and fish.

Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated horizontal steel cylinder or by spraying them into a chamber through which a current of hot air passes. In the first case, the dried material is scraped off the roller as a thin film which is then broken up into small, though still relatively coarse flakes. In the second process it falls to the bottom of the chamber as a fine powder.

Dried foods 'take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little time to cook them.

The chief point of the second paragraph is about ______.

A．the comparison of lean meat and fish

B．the removal of water in food

C．the water content in food

D．the relationship between water and food
