[单项选择]The men and women of Anglo-Saxon England normally bore one name only. Distinguishing epithets were rarely added. These might be patronymic, descriptive or occupational. They were, however, hardly surnames, Heritable names gradually became general in the three centuries following the Norman Conquest in 1066. It was not until the 13th and 14th centuries that surnames became fixed, although for many years after that, the degree of stability in family names varied considerably in different parts of the country.

In fact, over fifty percent of genuine British surnames derive from place names of different kinds, and so they belong to the last of our four main categories. Even such a name as Simpson may belong to this last group, and not t

[单项选择]

Suicide has been a cause of concern in most societies for a long time. The classical Greeks, for example, required people who wanted to kill themselves to get permission from the senate. While this law is not without humor by today’ s standards, it clearly shows an awareness of the problem in times gone by. In today’ s society, suicide is much more prevalent than we want to admit. Why do people try to take their own lives
The motives for suicide can be categorized into areas such as failure, wrath, the need for attention, stress, and so on. However, the qualities of a person who wants to take his own life change from person to person, making it difficult to depict (描写) the typical victim. To make the problem even more involved, people will often camouflage (掩盖) their true feelings, thus causing their friends to disregard problems that should be viewed as serious.
In the US, a network of centers has been created to attempt to prevent suicides. P
