A major reason for conflict in the animal world is territory. The male animal establishes an area. The size of the area is sufficient to provide food for him, his mate and their offspring. Migrating birds, for example, used up the best territory in the order of “first come, first（1）.” The late arrivals may acquire（2）territories, but less food is available, or they are too close to the（3）of the enemies of the species.（4）there is really insufficient food or the danger is very great, the animal will not（5）. In this way, the members of the species which are less fit will not have offspring. When there is conflict（6）territory, animals will commonly use force, or a show of force, to decide which will stay and which will go. It is interesting to note,（7），that animals seem to use only the minimum amount of force（8）to drive away the intruder. There is usually no killing. In the case of those ani¬mals which are capable of （9）each other great harm, （10） is a system for the losing animal to show the winning animal that he wishes to submit. When he shows this, the victor normally stops fighting.

The status of women in colonial North America has been well studied and described and can be briefly summarized. Throughout the colonial period there was a marked shortage of women, which varied with the regions and was always greatest in the frontier areas. This favorable ratio enhanced women’s status and position and allowed them to pursue different careers. The Puritans, the religious sect that dominated the early British colonies in North America, regarded idleness as a sin, and believed that life in an underdeveloped country made it absolutely necessary that each member of the community perform an economic function. Thus work for women, married or single, was not only approved, it was regarded as a civic duty. Puritan town councils expected widows and unattached women to be self-supporting and for a long time provided needy spinsters with parcels of land. There was no social sanction against married women working ； on the contrary, wives were expected to help their husbands in their trade and won social approval for doing extra work in or out of the home. Needy children, girls as well as boys, were indentured or apprenticed and were expected to work for their keep.The vast majority o£ women worked within their homes, where their labor produced most articles needed for the family. The entire colonial production of cloth and clothing and partially that of shoes was in the hands of women. In addition to these occupations, women were found in many different kinds of employment. They were butchers, silversmiths, gunsmiths, upholsterers. They tan mills, plantations, tanyards, shipyards, and every kind of shop, tavern, and boardinghouse. They were gatekeepers, jail keepers, sextons, journalists, printers, apothecaries, midwives, nurses, and teachers.1.What does the passage mainly discuss?2.It can be inferred from the passage that the Puritan were （ ）.3.According to the passage, what did the Puritans expect from married women?4.According to the passage, which products were made entirely by women?
