听力原文：In my childhood home, dinner was enjoyed with hushed voices, and the topics open

听力原文： In my childhood home, dinner was enjoyed with hushed voices, and the topics open for discussion were very much restricted. We were not allowed to bring up anything that was potentially unappetizing; body functions, bugs, murder and mayhem in general were all strictly forbidden topics. If I had to leave the table to use the toilet, I had to verbally excuse myself without mentioning what it was that I was going to do. "May I be excused, please？ I need to wash my hands." I would say. My mother would say, "Sure." My father would often play a joke on us by saying, "Your hands don't look dirty to me!"

As for eating, we did it quietly. No eating noises were allowed. Everything must be done as quietly as possible. Therefore, we had to eat with our mouths closed. To make a "smacking" noise was, perhaps, the worst offense possible. While drinking soup or coffee or wine "slurping" was also forbidden. If any sound whatever was created by our intake of food or beverage, it constituted bad manners! With that in mind, it was, of course, unthinkable to speak with one's mouth full of food, so speaking only occurred before or after one had taken in food and swallowed it.

How one sits at the table is also prescribed. One is to sit up straight with the recessive hand in one's lap holding a napkin while the dominant hand holds the fork or spoon. The only time one is allowed to have both hands on the table is when one is using a knife to cut something, but as soon as the cutting is done, the recessive hand goes back to the lap. Also, elbows are not allowed on the table. Therefore, one props the arm against the edge of the table just below the elbow. One should never reach for any food on the table; one should ask someone sitting near it to give it to you. "Would you please pass the potatoes？ .... May I trouble you for the salt？" These are phrases that you are likely to hear on any given night of the week at a family dinner.

Which of the following seems an unlikely topic over dinner？

A．The weather is going to be stormy.

B．A child was abused to death by his stepfather.

C．Oscar ceremony.

D．Family reunion at Christmas.

Eating Potatoes Gives Your Immune System a BoostEating potatoes is not only good for bowel

Eating Potatoes Gives Your Immune System a Boost

Eating potatoes is not only good for bowel health, but also for the whole immune system, especially when they come in the form. of a potato salad or eaten cold. In a study on an animal model, researchers in Spain found that pigs fed large quantities of raw potato starch (RPS) not only had a healthier bowel, but also decreased levels of white blood cells, such as leucocytes and lymphocytes in their blood. White blood cells are produced as a result of inflammation or disease, generally when the body is challenged.

The general down-regulation of leucocytes observed by the Spanish researchers suggests an overall beneficial effect, a generally more healthy body. The reduction in leucocytes levels was about 15 percent. Lower lymphocyte levels are also indicative of reduced levels of inflammation, but the observed reduction in both lymphocyte density and lymphocyte apoptosis is surprising.

In what was the longest study of its kind, pigs were fed RPS over 14 weeks to find out the effect of starch on bowel health. "The use of raw potato starch in this experiment is designed to simulate the effects of a diet high in resistant starch. " said study leader Jose Francisco Perez at the University Autonoma de Barcelona, Spain.

Humans do not eat raw potatoes, but they do eat a lot of foods that contain resistant starch, such as cold boiled potatoes, legumes, grains, green bananas, pasta and cereals. About 10 percent of the starch eaten by human is resistant starch--starch that is not digested in the small intestine and so is shunted into the large intestine where it ferments. Starch consumption is thought to reduce the risk of large bowel cancer and may also have an effect on irritable bowel syndrome (IBS).

Immunology expert Lena Ohman's team previously found that the overall lymphocyte levels do not vary for IBS patients, but that lymphocytes are transferred from the peripheral blood to the gut, which support the hypothesis of IBS being at least partially an inflammatory disorder. She says the decrease in lymphocytes observed by the Spanish is therefore interesting, and a diet of resistant starch may be worth trying in IBS patients. Ohman is currently at the Department of Internal Medicine, Goteborg University, Sweden. The study is published in the journal Chemistry and Industry, The magazine of the SCI.

What form. of potato is the most nutrient to the human body？

A．Potato soup.

B．Potato cake.

C．Potato salad.

D．Hot boiled potato.

Eight Tips for Eating WellA healthy balanced diet contains a variety of typos of food, inc

Eight Tips for Eating Well

A healthy balanced diet contains a variety of typos of food, including lots of fruit, vegetables and starchy (淀粉类) foods such as wholemeal bread and wholegrain cereals; some protein-rich foods such as meat, fish, eggs and lentils; and some dairy foods.

1. Base your meals on starchy foods

Starchy foods such as bread, cereals, rice, pasta and potatoes are a really important part of a healthy diet. Try to choose wholegrain varieties of starchy foods whenever you can.

Starchy foods should make up about a third of the food we eat. They are a good source of energy and the main source of a range of nutrients in our diet. As well as starch, these foods contain fiber, calcium, iron and B vitamins.

Most of us should eat more starchy foods —try to include at least one starchy food with each of your main meals. So you could start the day with a wholegrain breakfast cereal, have a sandwich for lunch, and potatoes, pasta or rice with your evening meal.

Wholegrain foods contain more fiber and other nutrients than white or refined starchy foods. We also digest wholegrain foods more slowly so they can help make us feel full for longer.

2. Eat lots of fruit and vegetable

Most people know we should be eating more fruit and vegetable. But most of us still aren't eating enough.

Try to eat at least 5 portions of a variety of fruit and vegetable every day. It might be easier than you think. Try adding up your portions during the meals throughout the day. You can choose from fresh, frozen, tinned, dried or juiced, but remember potatoes count as a starchy food, not as portions of fruit and vegetable.

3. Eat more fish

Most of us should be eating more fish —including a portion of oily fish each week. It's an excellent source of protein and contains many vitamins and minerals.

Aim for at least two portions of fish a week, including a portion of oily fish. You can choose from fresh, frozen or canned —but remember that canned and smoked fish can be high in salt.

What are oily fish？

Some fish are called oily fish because they are rich in certain types of fats, called omega 3 fatty acids, which can help keep our hearts healthy.

How much oily fish？

Although most of us should be eating more oily fish, women who might have a baby one day should have a maximum of 2 portions of oily fish a week (a portion is about 140g). And 4 is the recommended maximum number of portions for other adults.

Anyone who regularly eats a lot of fish should try and choose as wide a variety as possible.

4. Cut down on saturated (饱和的) fat and sugar

Fats

To stay healthy we need some fat in our diets. What is important is the kind of fat we are eating. There are two main types of fat:

- saturated fat —having too much can increase the amount of cholesterol (胆固醇) in the blood, which increases the chance of developing heart disease

- unsaturated fat—having unsaturated fat instead of saturated fat lowers blood cholesterol

Try to cut down on food that is high in saturated fat and have foods that are rich in unsaturated fat instead, such as vegetable oils, oily fish, avocados, nuts and seeds.

Foods high in saturated fat are: meat pies, sausages, meat with visible white fat, hard cheese, butter and lard, pastry, cakes and biscuits, cream, soured cream and creme fraiche, coconut oil, coconut cream or palm oil.

For a healthy choice, use just a small amount of vegetable oil or a reduced-fat spread instead of butter, lard or ghee. And when you are having meat, try to choose lean cuts and cut off any visible fat.

Sugar

Most people are eating too much sugar. We should all be

A．Y

B．N

C．NG

听力原文：During the early American colonial years, corn was more plentiful than wheat, so

听力原文： During the early American colonial years, corn was more plentiful than wheat, so corn bread was more common than wheat bread. Friendly Indians showed colonists how to grow corn and how to prepare it for food and pioneer women then improved the Indian cooking techniques. When people traveled, they went on foot or horseback, sleeping and eating in the forests. They carried corn bread for sustenance. The corn bread came to be called journeyeake. Later when roads and taverns were built and stagecoaches carried passengers, journeycake became johnnycake, a name many easterners still use for corn bread. The kinds of bread made with cornmeal were and still are almost without limit. Every region has its specialties.

From the start, southerners showed a preference for white eorm:neal, northerners for yellow. And pioneers on the frontier, when they ran out of yeast, made salt-rising bread. They stirred together water, a little water ground cornmeal, potatoes, and salt. They set the mixture, uncovered, in a warm place until it absorbed bacteria from the air and began to ferment. Then they removed the potatoes and used the liquid as leavening for their bread, made with white flour.

(33)

A．The colonists preferred corn bread.

B．Corn was more abundant.

C．The colonists did not know how to make wheat bread.

D．Corn bread did not spoil as rapidly as wheat bread did.
