Electronic mail has become an extremely important and popular means of communication. The convenience and efficiency of electronic mail are threatened by the extremely rapid growth in the volume of unsolicited commercial electronic mail. Unsolicited commercial electronic mail is currently estimated to account for over half of all electronic mail traffic, up from an estimated 7 percent in 2001, and the volume continues to rise. Most of these messages are fraudulent or deceptive in one or more respects. The receipt of unsolicited commercial electronic mail may result in costs to recipients who cannot refuse to accept such mail and who incur costs for the storage of such mail, or for the time spent accessing, reviewing, and discarding such mail, or for both. The receipt of a large number of unwanted messages also decreases the convenience of electronic mail and creates a risk that wanted electronic mail messages, both commercial and noncommercial, will be lost, overlooked, or discarded amidst the larger volume of unwanted messages, thus reducing the reliability and usefulness of electronic mail to the recipient. Some commercial electronic mail contains material that many recipients may consider vulgar or pornographic in nature. The growth in unsolicited commercial electronic mail imposes significant monetary costs on providers of Internet access services, businesses, and educational and nonprofit institutions that carry and receive such mail, as there is a finite volume of mail that such providers, businesses, and institutions can handle without further investment in infrastructure. Many senders of unsolicited commercial electronic mail purposefully disguise the source of such mail. Many senders of unsolicited commercial electronic mail purposefully include misleading information in the messages’ subject lines in order to induce the recipients to view the messages. While some senders of commercial electronic mail messages provide simple and reliable ways for recipients to reject (or ’opt-out’ o0 receipt of commercial electronic mail from such senders in the future, other senders provide no such ’opt-out’ mechanism, or refuse to honor the requests of recipients not to receive electronic mail from such senders in the future, or both. Many senders of bulk unsolicited commercial electronic mail use computer programs to gather large numbers of electronic mail addresses on an automated basis from Internet websites or online services where users must post their addresses in order to make full use of the website or service. The problems associated with the rapid growth and abuse of unsolicited commercial electronic mail cannot be solved by the government alone. The development and adoption of technological approaches and the pursuit of cooperative efforts with other countries will be necessary as well.
A．It costs money to receive them.
B．It’s free to store them.
C．It takes time to access them.
D．It takes time to throw them away.

TEXT B In early 19th century America, care for the mentally iii was almost non-existent: the afflicted were usually relegated to prisons, almshouses, or inadequate supervision by families. Treatment, if provided, paralleled other medical treatments of the time, including bloodletting and purgatives. However, in a wave of concern for the oppressed, some took action. Among these, Dorothea Dix was the leading crusader for the establishment of state-supported mental asylums. Through her efforts, the first state hospitals for the insane were built in New Jersey and Pennsylvania. She and other reformers sought humane, individualized care, with the rich and the poor housed together to insure high standards for all. The movement was generated by social reform, but throughout the century, mental illness was probed and analyzed, and" cures" prescribed by both the scientific and lay communities. "Moral treatment" was the predominating philosophy to cure the insane. This system was developed in late 18th century Europe, and by Benjamin Rush in the United States. It challenged the demonic explanations for insanity and emphasized the role of environment in determining character: improper external conditions could induce derangement. The "moral treatment" system was optimistic that an appropriate environment could facilitate cure, especially for those with acute ( not chronic) afflictions. Essential to this theory was a physiological basis for mental disorder: insanity was caused by brain damage. The brain’s surface was soft and malleable and physically altered by outward influence. This idea was closely related to phrenology, which assigned specific faculties to sections of the brain. The notion that mental illness resulted from physical impairment was rarely challenged, but the nature and treatment of ailments were continually debated. To find physical evidence for mental deficiencies, autopsies were performed on mental patients to discover lesions or other abnormalities. Although progress was made in the diagnosis of somatic diseases like tumors or syphilitic derangement, these efforts were frustrating and subjective. Also controversial was the fate of the chronically versus acutely iii: the differences between them, whether they should be housed together, and whether the chronically ill should be treated at all.
A．inadequate care by familiesB．social reformC．the effects of medical treatmentD．those who were not mentally iii
