小孤山

[宋]谢枋得

人言此是海门关,海眼无涯骇众观。天地偶然留砥柱,江山有此障狂澜。

坚如猛士敌场立,危似孤臣末世难。明日登峰须造极,渺观宇宙我心宽。

[注]①小孤山:位于安徽宿松县城南65公里的长江之中,是南宋军事要地。②谢枋得:宋弋阳(今属江西)人,以忠义自任,曾率军抗元。兵败后隐居福建一带,后被元人胁迫至燕京,绝食而死。③海眼:急流遇阻所形成的大漩涡。

I know what you’re thinking : pizza (比萨饼)? For breakfast? But the truth is that you can have last night’s leftovers in the a. m. if you want to... .

I know lots of women who skip breakfast (不吃早餐) , and they have a ton of different excuses for doing it . Some say they don’t have time. others think they’re “saving” calories (卡路里), still others just don’t like breakfast food .  .

But the bottom line is that eating in the morning is very important when you’re trying to lose weight. “Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking , R , D , who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it’s loaded with vegetables, and you stick to one small piece.  . .

Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southem California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.  . .

So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,” I put away the leftovers instead of eating more that night. Try it…you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.  . .

53. The word “leftovers” in Paragraph 1 probably means__________

food remaining after a meal                         B. things left undone

C. meals made of vegetables                     D. pizza topped with fruit . .

A. Working women usually have breakfast in a hurry

B. Many people have wrong ideas about breakfast.  . .

C. There are some easy ways of cooking a meal.  . .

D. Eating vegetables helps save energy.  . .

55. According to the last paragraph, it is important to____________.  . .

A. eat something for breakfast             B. be careful about what you eat . .

C. heat up food before eating it            D. eat calorie-controlled food . .

56. The text is written mainly for those_____________.  . .
