13．Tips for Shortening Homework Time
Homework can be a long，hard task for many students．（36）FStaying focused on the task at hand?while avoiding distractions?（干扰）is another struggle that many students face．Here are some strategies you can try to make homework time shorter and easier．
1．Power down electronics．While students think they?may need their computers for completing their assignments，devices can often be more of a distraction than helpful tools for getting homework done quickly．（37）G
2．Get a little exercise!Before beginning any homework，try having your child dance to music，or even do a few push-ups．（38）DThey will also help students finish homework in a more efficient manner．While some students are fine starting their work right after school，others benefit from this type of physical activity before beginning their school work．
3．（39）ASome students might prefer a desk in their room，while others may use a table in an office space or play room．Any of these choices work fine，as long as they are in a quiet area with minimal noise．
4．Arrange break times wisely．（40）CAnd they will reward themselves with a break after each part is complete．For instance，they might start with their first assignment．Once that is complete，they can give themselves a five-minute break for a snack．But make sure the break doesn't extend beyond the limited time．With these strategies，your child will become more efficient and can complete homework much faster．

D．These types of physical exercises will help increase alertness and?focus．
E．Doing some physical exercises can contribute to good health．

12．One of the best-known proverbs must be"Early to bed，early to rise，making a man healthy，wealthy and wise"．The promise of health，wealth and wisdom to those who join the ranks of the early retirees and risers must be particularly appealing to many people in our modern society．There is no doubt that one of the greatest concerns（关心） of modern man is his health．It is estimated that in the United States $200billion is spent on health care each year．The medical field has grown into such a big business that it employs 4.8million people； and it appears that in many places，more staff is needed to meet the demands of the people who are concerned about their physical well-being．?
Much more interest has been shown in preventive medicine in recent years．This is probably due in part to the increasing costs of medical treatment，but the writings of such people as Dr．Kenneth Cooper have also played an important role．In his book Aerobics Dr Cooper communicated his message of the benefits（好处） of exercise so effectively that many other authors have followed in his trail，and literally millions of readers have put on their sports shoes and taken to the highways and byways of America．A recent survey showed that over 17 million people are jogging．Many of these are so serious that they have trained themselves to run the 26 miles and 385 yards of the hard and tiring marathons that are organized all over the country．The last time I was in Honolulu，I was greatly surprised to see hundreds of people，young and old，running for their lives，and I discovered many of them have run in the Hawaiian Marathon．?
Exercise has also become a major part of conversation．At a dinner party recently，the president of a bank asked me，"You look like a runner； how far do you run each day？"A few days later when I appeared on a national television show，the host suddenly asked me if I was a regular runner．On both occasions the conversation turned to the subject of exercise and I found，as I have found whenever I have traveled recently，that this is a subject of being on many people's minds．Of course，there are still many people who are less than enthusiastic about exercise．They appreciate the philosophy of Robert M．Hutchins who said，"Whenever the thought of exercise occurs to me，I lie down till it passes．"

11．In the past，Americans used to think of the United States as a"melting pot"of immigrants（移民） from many different cultures to the United States，their old ways melted away and they became part of a completely new culture．The United States was likened to a big pot of soup，which had bits of flavor（味道，滋味） from each different culture．All of the different cultures were so well blended（混合，掺杂） together that it formed its own new flavor．?
Today，Americans realize that the simple"melting pot"theory is less true．Instead，different groups of people keep many of their old customs．Often groups of Americans from the same culture band together．They live together in distinctive communities，such as"Chinatowns"or"Little Italy"-areas populated almost exclusively（惟一，仅） by Americans of a single ethnic group-which can be found in many large American cities．Living in ethnic neighborhoods gives new Americans the security of sharing a common language and common traditions with people who understand them．?
In time，however，people from different backgrounds mix together．They also mix with native-born Americans．Old traditions give way to new customs．The children of immigrants are often eager to adopt new，American ways．They often want to dress in American?fashions，to speak English and to follow?American?social customs．By one estimate（估计），about 80 percent of European immigrants marry outside their own ethnic groups by the time they reach the third generation．Third generation means that their great-grandparents were immigrants．Yet as successive generations become more"Americanized"，they often retain significant elements of their ethnic country．
