第二节信息匹配(共5小题;每小题2分,满分10分)

请阅读下列应用文及相关信息,并按照要求匹配信息。请在答题卡上将对应题号的相应选项字母涂黑。

首先,请阅读下列的应用文:

A.Chapter One. …you probably have an image in your mind of what the “perfect’ or “ideal” body looks like. Try not to press yourself to look that way. Each person is born with genes that control the shape of his / her body. Everyone is different. It’s important to be comfortable with the body you have.

B.Chapter Two. …You use energy for everything you do. That energy comes from the food you eat. Too much food or too little exercise causes your body to store the extra energy in fat cells. But, if you exercise regularly and eat a healthy diet, you’ll feel healthier and stronger not to mention look great.

C.Chapter Three. … Your body runs best on foods high in carbohydrates and low in fat and sugar. Eating a healthy diet will provide your body with everything it needs to run smoothly. Your body breaks down proteins into amino acids(氨基酸), so you don’t need to take in the amino acids separately.

D.Chapter Four. …Exercise does more than just burn calories. For instance, regular exercise makes your muscles strong and flexible, and increases the amount of muscle you have. It also makes your heart stronger and lowers your blood pressure; …E. Chapter Five. …Always warm up and stretch for 5-10 minutes before you do strength or endurance exercises. Afterwards, take 10 minutes to cool down. Your heart should beat normally when you stop. Exercising with a group may help you to exercise regularly.

F. Chapter Six. …Supplementation of a mixture of essential amino acids will increase protein synthesis (蛋白质综合体). While supplementing with either carbohydrate or amino acids may limit muscle damage and stimulate (激励) protein synthesis, there is increasing evidence that the combination can have an addictive effect.
