以上的导入方法只是建议，大家选择其中一种或两种进行交叉使用即可。

【英语周报】人教版选修六教案：Unit附件

附件背景知识 Healthy Diet Focus on fruits. Eat a variety of fruits — whether fresh, frozen, canned or dried — rather than fruit juice for most of your fruit choices. For a 2,000 calorie diet, you will need 2 cups of fruit each day (for example, 1 small banana, 1 large orange, and 1 / 4 cup of dried apricots or peaches). Vary your veggies. Eat more dark green veggies, such as broccoli, kale and other dark leafy greens; orange veggies, such as carrots, sweetpotatoes, pumpkin and winter squash; beans and peas, such as pinto beans, kidney beans, black beans, garbanzo beans, split peas and lentils. Get your calcium-rich foods. Get 3 cups of low-fat or fat-free milk or an equivalent amount of low-fat yogurt and / or low-fat cheese (1 / 2 ounces of cheese equals one cup of milk) every day. For kids aged 2 to 8, it’s 2 cups of milk. If you don’t or can’t consume milk, choose lactose-free milk products and / or calcium-fortified foods and beverages. Make half your grains whole. Eat at least 3 ounces of whole-grain cereals, breads, crackers, rice, or pasta every day. One ounce is about 1 slice of bread, 1 cup of breakfast cereal, or 1 / 2 cup of cooked rice or pasta. Look to see that grains such as wheat, rice, oats, or corn are referred to as “whole” in the list of in gredients. Go lean with protein. Choose lean meats and poultry. Bake it broil it, or grill it. And vary your protein choices — with more fish, beans, peas, nuts and seeds. Know the limits on fats, salt and sugars. Read the Nutrition Facts label on foods. Look for foods low in saturated fats and trans fats. Choose and prepare foods and beverages with a little salt (sodium) and / or sugars (caloric sweeteners). Friends Key to Healthy Life Friends may influence health habits, such as smoking or drinking, or going to the doctor when a person has troubling symptoms, the study authors suggested. Friends may also have a significant impact on mood, self-esteem and coping mechanisms during difficult times. Interested in technology and innovation news? Add this s ite to your “Favorites” to find your way back easily next time. When it comes to living a long, healthy life, that’s what friends are for. New research from Australia suggests good buddies are even more important than close family ties in helping older people live longer. For the study, researchers at Flinders University in Adelaide interviewed about 1,500 people aged 70 and older. They asked each participant how much personal and phone contact they had with various social networks, including family and friends. Other factors known to influence longevity,
