人教版高一下英语必修三 培优练习第三周 一阅读理解。 A When we do something, we all have our own plans. Some people are born planners. I cant claim ( 宣称) to be one of that kind of people. Most of the time, I try to at least expect what might go wrong. I have taken to making lists and, although Im not yet achieving perfection, I usually manage to achieve goals. But there are times when even the best plans do not succeed. All that is left then is to smile and to make or do something using whatever is found. Hanukkah ( 光 明 节 ) came early this year, perhaps too soon after Thanksgiving to allow us to prepare well. During the first night of Hanukkah, the Hanukkah candles were nowhere to be found in the entire Dallas area where we lived. Birthday candles wouldnt work! The tall long thin candle fell in small drops. “What would our ancestors do?” I thought. “What shall I do now? Thats where ingenuity comes from. Dont be nervous and worried. Never let missing candles spoil a family celebration.” Later what we did find was a bag of tea lights. The long, silver bread tray became the base for our tea lights. The younger ones were wide-eyed and happy as Grandpa lit the first tea light and all recited the blessing. We sat at the dining table, happy to be together and the food was plentiful. No matter how imperfect it is, the fact that families gather to share a special event, an event that has held meaning for so many generations of families, is the meaning itself and forms the important part of the observance ( 仪式). What we need to remember, and to carry with us, is the knowledge that togetherness is much better than all other concerns. 21.

You dont need to remove certain kinds of foods from your diet, but rather select the healthiest ones. Protein Protein gives us the energy to get up and go and keep going while also supporting mood and cognitive function. Too much protein can be harmful to people with kidney ( 肾 ) disease, but the latest research suggests that many of us need more high-quality protein, especially as we grow up. That doesnt mean you have to eat more animal products a variety of plant-based sources of protein each day can ensure your body gets all the essential protein it needs. Fat Not all fat is the same. While bad fat can destroy your diet and increase your risk of certain diseases, good fat protects your brain and heart. In fact, healthy fat such as omega-3s is necessary to your physical and emotional health. Understanding how to include more healthy fat in your diet can help improve your mood and your well-being. Fiber Eating foods high in dietary fiber (grains, fruit, vegetables, nuts, and beans) can help you stay regular and lower your risk of heart disease, stroke, and diabetes. It can also improve your skin and even help you to lose weight. Depending on your age and gender, nutrition experts suggest you eat at least 21 to 38 grams of fiber each day for optimal (最 佳的) health. Unfortunately, most of us arent eating even half that amount.
