All of us eat every day, but most of us don’t understand nutrition(营养). How much do you know about good nutrition? Are the following statements true or false?
1. People who don’t eat meat can stay healthy.
True. As long as people eat enough milk, eggs and meat alternates(替代物), they can get enough protein.
2. Fresh vegetables cooked at home are always more nutritious than canned vegetables.
False. The difference depends more on how vegetables are prepared than whether they are fresh or canned. Vegetables cooked in too much water can lose a large quantity of vitamins.
3. Food eaten between meals can be just as good for health as food eaten at regular meals.
True. Nutritional value depends on what types of food you eat, not when you eat them. Eating an egg or an orange between meals can contribute to a good diet.
4. Taking extra vitamins beyond the recommended daily allowances won’t give you more energy.
True. It’s widely believed that extra vitamins provide more energy. But taking more than the baby needs doesn’t make it function better, just as overfilling your gas tank doesn’t make your car run better.
5. Natural vitamins are better supplements(补充)for the diet than synthetic vitamins.
False. There is no difference. A vitamin has the same properties(性质)and specific chemical structure whether made in a laboratory or taken from plant or animal parts.
6. Older people need the same amount of vitamins as younger people.
True. Older people need the same quantity of vitamins as younger people although they need fewer calories. Certain illnesses raise the requirements for some vitamins, but that is true for the young as well as the old.
7. Food grown in poor soil is lower in vitamins than food grown in rich sold.
False. The vitamins in our foods are made by the plants themselves. They don’t come from the soil.
However, the minerals in a plant depend on the minerals in the soil.
If you have answered these questions correctly, you can say you know much about food and nutrition by today’s standards. But remember that nutrition is a growing science and that may be aged as new information is obtained.

A．list today’s standards of some food and nutrition

查看习题详情和答案>>Internet regarding the elderly.They include things like "don't rely on others", "don't expect others to
help", "don't be talkative", and "dont't be so stubborn". The underlying message was that elderly
people should not take advantage of their old age to demand special favours from others, particularly
from the young.This of course flies_in_the_face_of the Chinese tradition of respecting the elderly.But,
in my opinion, Lisa's "requests" might not be totally unreasonable.Old people do sometimes behave
like they're "stubborn"and "talkative". Still, the young woman is rudely insensitive to why the elderly
behave that way.As people get old, they become increasingly weakened physically.So it's natural for
them to ask for more help from others.As their memories decline, they tend to be talkative because
they easily forget what has just been said.The American psychologists D. R.Atkinson and G. Hackett
said that the brain is characterized by flexibility.It has the ability (most pronounced up to the age of 12)
to change itself as a result of experience.But, as the brain ages, this flexibility decreases.As a result, the
elderly are often inflexible in their ways.
Therefore, old people need real care and deserve to be taken care of.Many have devoted most of
their lives to the wellbeing of the family or social.Their aging is no reason for showing prejudice (偏见)to
them. According to Chinese tradition, older people are to be respected.As are Westerners.
I live in the US for eight years, and in Hong Kong for 13.Never have I seen or heard anyone who
would openly tell old people "to behave themselves".
We may encourage old people to be more selfreliant.But rudely demanding that they do so is ageism.
That's where the difference lies.
1. What does Lisa think of the elderly?
A. The elderly hate to rely on the others.
B. The elderly should take advantage of their old age.
C. They are not talkative but stubborn.

B. shows disagreement with

D. draws a conclusion from
3. What's the writer's attitude towards this problem?
A. The young woman is too sensitive to why the elderly behave that way.
B. The elderly naturally ask for more help from others, because their brain is characterized by flexibility.
C. The elderly are often inflexible in their ways, which makes the young suffer.
D. The elderly deserve to be taken care of and we shouldn't show our prejudice because of their aging.
4. The last three paragraphs really want to show that________.
A. we should respect the elderly
B. the people in the US or Hong Kong respect the older people
C. old people should be encouraged to be more selfreliant
D. different ideas about the elderly are allowed to exist
Age has its special advantages in America. And one of the more impressive of them is the senior citizen discount. Anyone who has reached a certain age – in some cases as low as 55 – is automatically entitled to plenty of price reductions at nearly every level of commercial life. Eligibility （资格） is determined not by one’s need but by the date on one’s birth certificate. Practically the discounts have become a routine part of many businesses – as common as color televisions in motel rooms and free coffee on airliners.
People with gray hair often are given the discounts without even asking for them; yet, millions of Americans above age 60 are healthy and solvent （有支付能力的）. Businesses that would never dare offer discounts to college students or anyone under 30 freely offer them to older Americans. The practice is acceptable because of the widespread belief that “elderly” and “needy” are synonymous（同义的）. Perhaps that once was true, but today, to be sure, there is economic variety within the elderly, and most of them aren’t poor.
It is impossible to determine the effect of the discounts on individual companies. For many firms, they are a stimulus to income. But in other cases the discounts are given at the expense, directly or indirectly, of younger Americans. Moreover, they are a directly annoy some politicians and scholars who consider it a coming conflict between the generations.
Generational tensions are being fueled by continuing debate over Social Security benefits, which mostly involves a transfer of resources from the young to the old. Employment is another point. Supported by laws and court decisions, more and more older Americans are refusing the retirement dinner in favor of staying on the job — thereby lessening employment and promotion opportunities for younger workers. Far from a kind of charity they once were, senior citizen discounts have become a powerful economic privilege（特权） to a group with millions of members who don’t need them.
It no longer makes sense to treat the elderly as a single group whose economic needs deserve priority over those of others. Senior citizen discounts only enrich the myth that older people can’t take care of themselves and need special treatment; and they threaten the creation of a new myth, that the elderly are ungrateful and taking for themselves at the expense of children and other age groups. Senior citizen discounts are the heart of the very thing older Americans are fighting against — discrimination by age.

D．the senior discounts can make up for the lack of the Social Security system
3．What does the author think of the Social Security system?
A．It encourages elderly people to retire in time.
B．It opens up broad career chances for young people.
C．It benefits the old at the expense of the young.
D．It should be strengthened by laws and court decisions.
4．What does the author mainly argue in the passage?
A．Senior citizens should fight hard against age discrimination.
B．The elderly are selfish and taking senior discounts for granted.
C．Senior citizen discounts may well be a type of age discrimination.
D．Discounts should be given to the economic needs of senior citizens.

People in many places are digging up the old folk stories and the messages in them.For example,most American storytellers get their tales from a wide variety of sources,cultures,and times.They regard storytelling not only as a useful tool in child education,but also as a meaningful activity that helps adults understand themselves as well as those whose culture may be very different from their own.
“Most local stories are based on a larger theme,”American storyteller Opalanga Pugh says,“Cinderella(灰姑娘),or the central idea of a good child protected by her goodness,appears in various forms in almost every culture of the world.”

Pugh spent several years in Nigeria,where she learned how closely storytelling was linked to the everyday life of the people there.The benefits of storytelling are found everywhere,she says.
“I learned how people used stories to spread their culture,”she says.“What I do is to focus on the value of stories that people can translate into their own daily world of affairs.We are all storytellers.We all have a story to tell.We tell everybody’s story.”
