My father was a gruff man. I couldn't remember the last time he had tenderly stroked my cheek, tousled my hair or used a term of endearment when calling my name. His diabetes had given him a short temper and he screamed a lot. I was envious when I saw other fathers plant gentle kisses on their daughters' foreheads or impulsively give them a big bear hug. I knew that he loved me and that his love was deep. He just didn't know how to express it.
It was hard to say "I love you' to someone who didn't say it back. After so many disappointing times when I would flinch from his sharp rebuff I began to withdraw my own warm displays of affection. I stopped reaching out or hugging or kissing him. At first this act of self-restraint was conscious. Later it would become automatic, and finally it was ingrained. The love between us ran strong but silent.
One rare evening out, when my mother had successfully coaxed my usually asocial father to join us for a night in the town, we were sitting in an elegant restaurant that boasted a small but lively band. When it struck up a familiar waltz tune, I glanced at my father. He suddenly appeared small and shrunken to me not powerful and intimidating as I had always perceived him.
All the old hurts welled up inside but I decided to dare one last time.
"Dad, You know I've never ever danced with you. Even when I was a little girl, I begged you, but you never wanted to! How about right now? " I waited for the usual brusque reply that would once again slice my heart into ribbons. But instead he considered me thoughtfully and then a surprising twinkle appeared in his eye." I have been remiss in my duties as a father then." he uncharacteristically joked. "Let's hit the floor and I'll show you just what kind of moves an old geezer like me still can make!"
My father took me in his arms. Since earliest childhood I hadn't been enfolded in his embrace. I felt overcome by emotion.
As we danced, I looked up at my father intently but he avoided my gaze. His eyes swept the dance floor, the other diners and the members of the band. His scrutiny took in everyone and everything but me. I felt that he must already be regretting his decision to join me for a dance; he seemed uncomfortable being physically close to me.
"Dad," I finally whispered tears in my eyes. "Why is it so hard for you to look at me?" At last his eyes dropped to my face and he studied me intently. "Because I love you so much", he whispered back. "Because I love you. " I was struck dumb by his response. It wasn't what I had anticipated. But it was of course exactly what I needed to hear. His own eyes were misty and he was blinking.
I had always known that he loved me, I just hadn't understood that his vast emotion had frightened him and made him mute. His taciturn manner hid the deep emotions flowing inside. "I love you too, Dad" I whispered back softly. He stumbled over the next few words" I ... I'm sorry that I'm not demonstrative." Then he said "I've realized that I don't show what I feel. My parents never hugged or kissed me and I guess I learned how not to from them. It's... it's.., hard for me. I'm probably too old to change my ways now but just know how much I love you." "Okay" I smiled.
When the dance ended, I brought Dad back to Mom waiting at the table and excused myself to the ladies' room. I was gone just a few minutes but during my absence everything changed.
There were screams and shouts and scrapings of chairs as I made my way back across the room. I wondered what the commotion was all about. As I approached the table I saw it was all about Dad. He was slumped in his chair ashen gray. A doctor in the restaurant rushed over to handle the emergency and an ambulance was called but it was really all too late. He was gone. Instantly they said.
What had suddenly made me after so many years of steeling myself against his constant rejection ask hi
A.He was a bad-tempered man because of the disease he had suffered.
B.He was an asocial man with little idea of using body language.
C.He was an affectionate father who seldom joked.
D.He was a loving father without much warm demonstration of love.

第二篇 Why Not Eat Breakfast?Breakfast is not only the most important meal of the day, it is also the most neglected or skipped. Common reasons for not eating breakfast include lack of time, not feeling hungry, traditional dislike for breakfast, and dieting. Breakfast simply means "break the fast." Your body spends at least six to twelve hours each night in a fasting state. In the morning your body needs energy to rev up (转动起来) into high gear for the day's work ahead. If you skip breakfast, you are likely to concentrate less effectively in the late morning, feel irritable, short-tempered(易怒的), tired, or weak.
When you choose not to eat breakfast, your body stays in slow gear. Also, people
who skip breakfast often binge (无节制的大吃) later in the day at other meals or eat a high-calorie (高卡路里) snack in the morning. Breakfast eaters tend to eat less fat during the day, have more strength and endurance and better concentration and problem-solving ability. A good breakfast should provide up to 1/3 of your total calorie needs for the day. On the average, we eat 400 less calories for breakfast than for dinner. If breakfast doesn't appeal to you in the morning, try eating a lighter-dinner, earlier in the evening or save half your dinner for breakfast in the morning.
If you still aren't hungry in the morning, start with something small like juice or toast or have a mid-morning snack later when you are hungry. Not eating breakfast can also cause you to overeat, since a fall in blood sugar often makes you feel very hungry later. To make matters worse, since your body is in a slowed state, it will not be able to burn those extra calories very efficiently. If you feed your body healthy snacks and meals throughout the day, you are less likely to become extremely hungry and stuff yourself as soon as you begin to eat. Since breakfast is the first and most important meal of the day, choosing the right fuel is important. The best breakfast foods are fruits, juice, lean meat, and grain products such as breads, rice, noodles, and cereals.
第36题:The word fast\" in the phrase \"break the fast\" in paragraph 2 means
A."a series of quick actions".
B."a habit of eating".
C."a period of not eating".
D."a strict rule".
