话题链接:Proper habits of nutrition can be developed by paying attention to the variety of foods included in the diet; and the quantity of each kind of food eaten.A diet, or the food regularly eaten, must contain all the nutritional(营养的)elements.Different food contains different vitamins(维生素),let's look at the food one by one.
EGGS
Eggs are an excellent source of complete protein(蛋白质);they contain all essential amino acids(氨基酸).One large egg contains 7 or 8 grams of first-class protein.Also found in eggs are vitamins A, B2, D, and E; niacin(烟酸);copper; iron; phosphorus(磷);and unsaturated(不饱和的)fats.The egg yolk contains the richest known source of choline, found in lecithin and necessary for keeping the cholesterol (胆固醇)within the egg emulsified(蛋白).The egg yolk also contains biotin(维生素H),one of the B-complex vitamins.
FIBER
Fiber is the part of food that is not digested by the human body, such as the skin of an apple and the husk(壳,皮)of a wheat kernel.The normal functioning of the intestinal tract depends upon the presence of adequate fiber.A low-fiber diet has been associated with heart disease, cancer of the colon and rectum(直肠),diverticulosis(瘢痕形成),varicose veins(纹理),phlebitis(静脉炎),and obesity.
FISH
Fish are excellent sources of high-grade protein, polyunsaturated fatty acids, and minerals, especially iodine(碘)and potassium(钾).Fish are categorized as freshwater fish, saltwater fish, and shellfish.These types differ slightly in nutritive value.Freshwater fish provide magnesium(镁),phosphorus, iron, and copper.Saltwater fish and shellfish are rich in iodine, fluorine(氟),and cobalt (钴).Fatty fish, such as halibut(比目鱼),mackerel(鲭鱼),and salmon, are good sources of vitamins A and D.Herring, oysters, and sardines contain vanadium and zinc.Shellfish are low fatty acids but are relatively high in cholesterol.
FRUITS
Fresh fruits are good sources of vitamins and minerals, especially vitamin A and C, carbohydrates in the form of cellulose and natural sugars, and water.They are good substitutes of such high-carbohydrate(碳水化合物)foods as candy, cookies, and cakes, which contain few nutrients.Yellow fruits, such as apricots, cantaloupe(香瓜),and persimmons(柿子),are good sources of carotene(胡萝卜素),which is converted to vitamin A.Aside from acerola cherries and rose hips, the best natural sources of vitamin C are the citrus fruits, such as oranges, grapefruit, lemons, and tangerines(橘);other sources of vitamin C are cantaloupe, strawberries, and tomatoes.Apples and bananas contain valuable bulk fiber in the form of indigestible(不可吸收的)cellulose, which is needed for regular bowel movement.Bananas are high in magnesium(镁)and may be useful for treatment of diarrhea, colitis, ulcers, and certain cases of protein allergies.Bananas and pears are the highest in natural sugars.
GRAINS
Grains are often referred to as cereals ;they are the seeds of various grasses such as wheat, oats, rice, and barley.Often called the “staff of life”, they provide the bulk of the world's food supply.Common foods made from these grains are flours, breads, breakfast cereals, and macaroni.

Reading Comprehension
Section B
Directions:Read the following passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.
Are organically grown foods the best food choices?The advantages claimed for such foods over conventionally (传统地) grown and marketed food products are now being debated. Supporters of organic foods—a term whose meaning varies greatly—frequently announce that such products are safer and more nutritious than others.
The growing interest of consumers in the safety and nutritional quality of the typical North American diet is a welcome development. However, much of this interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, the flood of written material advancing such claims makes it difficult for the general public to separate fact from fiction. As a result, claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health have become widely publicized.
Almost daily the public is besieged by claims for “no-aging” diets, new vitamins and other wonder foods. There are numerous unproved reports that natural vitamins are superior to synthetic ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than fumigated grains and the like.
One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is real cause for concern if consumers,particularly those with limited incomes, distrust the regular food supply and buy only expensive organic foods instead.
1.The “welcome development” mentioned in paragraph 2 is an increase in ______.
A. attention to food safety and nutrition among north Americans
B. the nutritional quality of the typical North American diet
C. the amount of healthy food grown in North America
D. the number of consumers in North America
2. The author implies that there is cause for concern if consumers buy organic foods instead of conventionally grown foods because ______.
A. organic foods can be more expensive but are often not better than conventionally grown foods
B. many organic foods are actually less nutritious than similar conventionally grown foods
C. conventionally grown foods are more readily available than organic foods
D. too many farmers will stop using conventional methods to grow food crops
3.What is the author’s attitude toward the claims made by advocates of health foods?
A. Enthusiastic. B. Favorable. C. Neutral. D. Distrustful.
The meal you eat after exercising matters! No matter what time of day you exercise, the key is to follow the exercise up with meals that supply enough nutrition. For the best results, eat within thirty to sixty minutes after exercising, when the muscles are at the best time to take in nutrients.
Here are some ideas for meals after exercising:
Home-made sports—recovery drink
Mix banana, milk, and yogurt to make a fresh and satisfying sports—recovery drink. Dairy products like milk and yogurt work double duty, providing both protein and carbohydrates. A cup of coffee, on the other hand, is a poor choice.
Protein—packed sandwich
You can’t go wrong with a sandwich after exercising—it’s got everything in a hand—held package. Sandwiches provide the salt you need to replace what you have lost by sweating, while the tomatoes in them supply plenty of Vitamin C. Try using whole—wheat bread to give yourself more fiber. The cheese and fresh vegetables in sandwiches are also great for helping tired muscles recover.
Power breakfast
An egg sandwich is a perfect post—exercise breakfast. There’s protein in both the yolk(蛋黄) and the white of the egg. This recipe increases your protein intake while keeping calories and fat under control. Eggs also contain zinc(锌), which helps protect against disease.
Plant—based protein
Beans are an amazing source of plant—based protein and carbohydrates. Make a large bowl of bean salad in the beginning of a week, and you’ll have a great post—exercise meal that is ready whenever you need it.
53.Why does the author advise eating a protein—packed sandwich after exercising?
A.It helps increase the protein in your body. B.It has plenty of fat and calories.
C.The things in it help you recover. D.It is an amazing source of carbohydrates.
54.What should you do when your muscles feel tired?
A.Eat cheese and fresh vegetables.
B.Drink as much milk and yogurt as possible.
C.Eat whole—wheat bread instead of a sandwich.
D.Eat and drink as soon as possible.
55.Which of the following is NOT true according to the passage?
A.It’s the best time for muscles to take in nutrients within 30 to 60 minutes after exercising.
B.It’s best for you to have an egg sandwich after exercising.
C.A cup of coffee will help you recover after exercising.
D.Bean salad is another great meal for post—exercising.
56.What is the passage mainly about?
A.The healthy eating habits of athletes. B.The best time for exercising.
C.How to warm up before exercising. D.What to eat after exercising.

The most important holiday in spring, especially for Christians, is Easter. This Christian holiday is not on the same date every year,but it’s always on a Sunday.
