Tides arc created mainly by the pull of the moon on the earth. The moon’s pull causes water in the oceans to be a little deeper at a point closest to the moon and also at a point farthest from the moon on the opposite side of the earth. These two tidal "waves" follow the apparent movement of the moon around the earth and strike nearly every coast line at interval of about twelve hours and twenty-five minutes. After reaching a high point, the water level goes down gradually for a little more than six hours and then to rise toward a new high point. Hence, most coast lines have two tides a day, and the tides occur fifty minutes late each day. Differences in the coast line and in channels in the ocean bottom may change the times that the tidal wave reaches different points along the stone coast line. The difference in water level between high and low tide varies from day to day according to the relative positions of the sun and the moon because the sun also exerts a pull on the earth, although it is only about half as strong as the pull of the moon. When the sun and the moon are pulling along the same line, the tides rise higher, and when they pull at right angles to one another, the tide is lower. The formation of the coast line and variations in the weather are additional factors which can affect the height of tides. Some sections of the coast are shaped in such a way as to cause much higher tides than are experienced in other areas. A strong wind blowing toward the shore may also cause tides to be higher. What may be concluded from the information presented in the passage about time of tide along different coast lines

Computer Crime A computer crime is generally defined as one that involves the use of computers and software for illegal purposes. This doesn’t mean that all the crimes are new types of crime. On the contrary, many of these crimes, such as embezzlement of funds, the alteration of records, theft, vandalism, sabotage, and terrorism, can be committed without a computer. But with a computer, these offenses can be carried out more quickly and with less chance that the person responsible for the crime will be discovered. Computer crimes are on the rise and have been for the last twelve years. Just how much these computer crimes cost the American public is in dispute, but estimates range from $ 3 billion to $ 5 billion annually. Even the FBI, which attempts-to keep track of the growth or decline of all kinds of crimes, is unable to say precisely how large a loss is involved; however, it estimates that the average take from a company hit by computer crime is $ 600,000. A number of reasons are given for the increase in computer crime: (A) more computers in use and, thus, more people who are familiar with basic computer operation; (B) more computers tied together in satellite and other data-transmission networks; and (C) the easy access of microcomputers to huge mainframe data bases. The Criminal Movies and newspaper stories might lead us to believe that most computer crimes are committed by teenage "hackers"—brilliant and basically good children who let their imagination and technical genius get them into trouble. But a realistic look at the crimes reveals that the offender is likely to be an employee of the firm against which the crime has been committed, i. e.. an "insider". Difficulty of Detection and Prevention Given the kind of person who commits a computer crime and the environment in which the crime occurs, it is often difficult to detect who the criminal is. First of all, the crime may be so complex that months or years go by before anyone discovers it. Second, once the crime has been revealed, it is not easy to find a clear trail of evidence that leads back to the guilty party. After all, looking for "weapons" or fingerprints does not occur as it might in the investigation of more conventional crimes. Third, there are usually no witnesses to the computer crime, even though it may be taking place in a mom filled with people. Who is to say if the person at the next terminal, calmly keying in data, is doing the company’s work or committing a criminal act Fourth, not enough people in management and law enforcement know enough about computer technology to prevent the crimes. Authorities have to be familiar with the computer’s capabilities within a given situation to guard against its misuses. In some large cities, such as LosAngeles, police departments have set up specially trained computer crime units. But even when an offender is caught, the investigators, attorneys (律师), judges, or juries may find the alleged crime too complicated and perplexing to handle. More attorneys are specializing in computer law and studying the computer’s potential for misuse. After a computer crime has been discovered, many companies do not report it or prosecute (起诉) the person responsible. A company may not announce the crime out of fear that the pubic will find out the weaknesses of its computer system and lose confidence in its organization. Banks, credit card companies, and investment firms are especially sensitive about revealing their vulnerabilities (脆弱性) because they rely heavily on customer trust. To avoid public attention, cautious companies will often settle cases of computer tampering out of court. And if cases do go to trial and the offenders are convicted, they may be punished only by a fine or light sentence because the judge or jury isn’t fully trained to understand the nature and seriousness of the crime. Not all companies are timid in apprehending computer criminals. For example, Connecticut General Life Insurance Company decided it had to get tough on violators. So when the company discovered that one of its computer technicians had embezzled $ 200,000 by entering false benefit claims, it presented it findings to the state’s attorney and aided in the prosecution of the technician. The technician was found guilty and sentenced to prison, not just for the computer misuse, but also for grand theft and insurance fraud. Connecticut General now has a policy of reporting all incidents of theft or fraud, no matter how small. Connecticut General Life Insurance company is cited as ______ of companies that took serious measures to fight against computer crimes.
