start later in the morning The research says that teenagers are more awake later at night than adults are When staying up late at night the teenagers have problems learning early in the morning 2 Researchers in the state of Rhode Island measured the amount of the hormone 荷尔蒙 melatonin 降黑素 in people s mouths at different times of the day Melatonin causes people to feel sleepy 3 They found that melatonin levels rise later at night in teenagers than they do in children and adults It remains at higher levels in teenagers later in the morning They said this shows that teenagers have difficulty learning early in the morning Yet most school systems in the United States begin high school classes at about seven o clock 4 A few school districts have made some changes In 1996 school officials in Edina Minnesota changed the start of classes from seven thirty to eight thirty Two years later the nearby city of Minneapolis did the same Teachers there reported that students were no longer sleepy in class and were happier Staying in school later in the day did not seem to be a problem for students who had jobs after school either 5 Health experts say that teenagers need between eight and nine hours of sleep a night Students are likely to be late for school fail to do their homework fall asleep in class and have trouble taking part in class 3 discussions 6 Some people however don t support a later start time because they say that it would limit the time for practicing sports after school However the Minnesota schools found that this did not hurt school sports competitions 7 More American school districts are discussing the possibility of changing high school start times Researchers and teenagers say that they cannot make the change quickly enough 1 What is the best title of

twentieth century many people thought that the American family was falling apart A century later we know that this was not the case However although the family is still alive in the United States its 4 size and shape were very different from 100 years ago In the late 1800s and early 1900s there were mainly two types of families in the United States the extended and the nuclear The extended family usually includes grandparents parents and children living under the same roof The nuclear family consists of only parents and children Today there are many different kinds of families Some people live in traditional families that is a stay home mother a working father and their own biological children Others live in two paycheck families single parent families adoptive or foster families blended families where men and women who were married before marry again and combine the children from previous marriages into the new families child less families and so on What caused the structure of the family to change In the early 1900s the birthrate began to fall and the divorce rate began to rise Women were suddenly choosing to go to college and take jobs outside the home In the 1930s and 1940s many families faced serious financial or money problems during the Great Depression when many people lost their jobs During World War 1939 1945 5 million women were left alone to take care of their

people married at a younger age and had more children than the previous generation It was unusual for a mother to work outside the home during the years when her children were growing up Families began leaving cities and moving into single family homes in the suburbs The traditional family seemed to be returning In the years between 1960s and 1990s there were many important changes in the structure of the family From the 1960s to the early 1970s the divorce rate doubled and the birthrate fell by half The number of single parent families tripled and the number of couples living together without being married doubled again In fact the single parent household once unusual has replaced the traditional family as the typical family in the States If we can judge from history however this will probably change again in the twenty first century 5 The Changes of the American Family Main comparisonsContexts There were two 2 types of families in the past 3 the extended and the nuclear

Marcia M Rich who practises general dentistry in Newholt She is also a lecturer at the University and a writer for the monthly magazine Your Dentist Cares 2 My answer to the first question is to
