The job of raising children is a tough one. Children don’t come with an instruction manual. And each child is different.41)__________.To Americans, the goal of parents is to help children stand on their own two feet. From infancy, each child may get his or her own room. As children grow, they gain more freedom to make their own choices. Teenagers choose their own forms of entertainment, as well as the friends to share them with.42)__________. But once they "leave the nest" at around 18 to 21 years old, they want to be on their own, not "tied to their mother’s apron strings."43)__________. When children become adults, their relationship with their parents becomes more like a friendship among equals. But contrary to popular belief, most adult Americans don’t make their parents pay for room and board when they come to visit. Even as adults, they respect and honor their parents.44)__________.Many Americans have strong feelings about which type of arrangement is best. Some argue that attending a day care center can be a positive experience for children. Others insist that mothers are the best caregivers for children. A number of women are now leaving the work force to become full-time homemakers.45)__________.Many parents feel that an old-fashioned spanking helps youngsters learn what "No!" means. Others prefer alternate forms of discipline. For example, "time outs" have become popular in recent years. Children in "time out’ have to sit in a corner or by a wall. They can get up only when they are ready to act nicely. Older children and teenagers who break the rules may be grounded, or not allowed to go out with friends. Some of their privileges at home--like TV or telephone use—may also be taken away for a while. Although discipline can’ t fun for parents or children, it’s a necessary part of training.Being a parent is a tall order. It takes patience, love, wisdom, courage and a good sense of humor to raise children (and not lose your sanity). Some people are just deciding not to have children at all, since they’re not sure it’s worth it, But raising children means training the next generation and preserving our culture. What could be worth more than thatA. The relationship between parents and children in America is very informal. American parents try to treat their children as individuals--not as extensions of them- selves. They allow them to fulfill their own dreams. Americans praise and encourage their children to give them the confidence to succeed.B. So parents sometimes pull their hair out in frustration, not knowing what to do. But in raising children—as in all of life—what we do is influenced by our culture. Naturally then, American parents teach their children basic American values.C. Disciplining children is another area that American parents have differing opinions about.D. Naturally, every parent wants their child to be safe, whether the child is online or on the school bus. And certainly if you suspect your child is involved in drugs, inappropriate relationships, or other dangerous situations, it’ s your responsibility to step in and intervene using whatever tools are necessary.E. When they reach young adulthood, they choose their own careers and marriage partners. Of course, many young adults still seek their parents’ advice and approval for the choices they make.F. Most young couples with children struggle with the issue of childcare. Mothers have traditionally stayed home with their children, In recent years, though, a growing trend is to put preschoolers in a day care center so Mom can work.G. Keep the family PC in an accessible part of the house where you can easily keep an eye on your children’s activity, and limit the amount of time your kids spend online. Discuss some of the dangers of the Internet with older children, and make sure they understand that they should not provide personal information such as their name, address, or school to people they meet online, and they should never agree to meet an online acquaintance face to face without your permission. 45

Prolonged and excessive use of alcohol can seriously undermine an individual’s health. Physical deterioration occurs. Large quantities of alcohol can directly damage body tissue and indirectly cause malnutrition. Nutritional deficiencies can result for several reasons. Alcohol contains empty calories, which have no significant nutritive value. When consumed in substantial amounts, alcohol curbs one’ s appetite for more wholesome foods. Excessive alcohol intake can interfere with the proper digestion and absorption of food. Therefore, even the heavy drinker who does eat a well-balanced diet is deprived of me essential nutrients. Maintenance of a drinking habit can deplete economic resources otherwise available for buying good, wholesome food. Malnutrition itself further reduces the body’ s ability to utilize the nutrients consumed. The result of damaged tissue and malnutrition can be brain injury, heart disease, diabetes, or cancer of the liver, and weakened muscle tissue. Untreated alcoholism can reduce one’s life span by ten to twelve years. Heavy alcohol consumption also affects the body’s usage of other drugs and medications. The dosages required by excessive drinkers may differ from those required by normal or non-drinkers. Serious consequences can be incurred unless the prescribing physician is aware of the patient’s drinking habits. Sudden death may result from excessive drinking. It might occur when the individual has ingested such a large amount of alcohol that the brain center controlling breathing and heart action is adversely affected, or when taking some other drugs, particularly sleep preparations along with alcohol. Death, as a result of excessive drinking, can come during an automobile accident since half of all fatal traffic accidents involve the use of alcohol. Many self-inflicted deaths, as well as homicides, involve the use of alcohol. It is important to remember that alcohol is a drug that is potentially addictive. Once the user is hooked on alcohol, withdrawal symptoms occur when it is not sufficiently available to body cells. At the onset of developing alcohol addiction, these symptoms may be relatively mild and include hand tremors, anxiety, nausea, and sweating. As dependency increases, so does the severity of the withdrawal syndrome and the need for medical assistance to cope with it. In 1956 the American Medical Association supported the growing acceptance of alcoholism as an illness, falling under the treatment jurisdiction of the medical profession. Since then, the medical resources for problems of acute and chronic intoxication have increased and improved. Which of the following statements is false
