The Energy Diet
How can I lose weight when every time I go on a diet, I'm so exhausted that I can barely make it through the day? So goes the complaint of many men and women who are concerned about being overweight. What many people don't realize is that a healthful weight-loss plan can actually boost your energy. The key is to eat smart. And then combine this healthful diet with some physical activity. Here are six pointers to get you started.
1.____
Consume too few calories and you'll have less energy, and decrease the amount of calories burned. "That's because one of the ways the body protects itself from starvation is to slow down its metabolism," explains Dr. Donald Hensrud, a nutrition professor at the Mayo Clinic, in Rochester, Minn. So how many calories do you need to feel energized while also slimming down? A healthful weight-loss rate is roughly one-and-a-half pounds per week, and the calorie intake to achieve this depends on your age, weight, and activity level.
2.____
The key to keeping your energy level up when you diet is to eat balanced meals that supply all the nutrients you need. "Vitamins and minerals act like spark plugs," explains Kristine Clark, director of sports nutrition at Pennsylvania State University. "They help release the energy in nutrient-rich food." Try to follow USDA guidelines. They call for 6 to 11 servings per day from the bread, cereal, rice, and pasta group; three to five servings of vegetables; two to four of fruits; two or three of milk or cheese; two or three of meat, fish, or eggs. Avoid fried and creamy dishes, and keep consumption of sweets and desserts to a minimum.
3____
When you go for five to six hours without food, the amount of fuel in your system starts to run low, and you begin to feel tired. Therefore, says Kristine Clark, it's important to eat at regular intervals to keep your energy up. If you exercise, it's important to make sure you have "fuel in the tank" before you head for the gym. Avoid eating a large number of calories at one time, since it's harder to control your total calorie intake, making weight gain more likely.
4____
About 10% of women of childbearing age in the United States are iron deficient. Iron is essential for energy and endurance because it is a vital component of red blood cells, which carry oxygen to working muscles. "Fatigue and listlessness can be directly associated with too little iron," says Frances Berg, a licensed nutritionist in Hettinger, N.D. The best sources of iron are meat, poultry, and some fish. Other sources: fortified cereals, dried beans, dried fruits, and peas.
5____
"I don't have the energy to exercise!" say many dieters. Indeed, a 1998 survey, developed in part by the Center for Sports Medicine at Penn State, found that over 70% of respondents cited "too tired" or "lack of energy" as key reasons to skip exercising. Yet exercise is exactly what these people need. And, lastly, don't try to do too much too soon. Consider breaking your exercise into small units. Instead of trying to do 30 minutes in one chunk, accumulate exercise in short bouts （一场，一回）every day by mowing the lawn, walking to work, or climbing stairs instead of taking an elevator. It won't be long before you reap （收获）the rewards. Imagine carrying a 15-pound sack of groceries around all day. Then think about how much more energy you'd have if you put that sack down.

Rhinos(犀牛) are big and can be dangerous. They are also shy and seldom seen. Once there were hundreds of rhino species, but today there are only five. One ancient rhino called Indricotherium was the largest land mammal that ever lived. It was 5m high at the shoulders, and 8.5m long— twice the size of today’s biggest elephant! The living rhinos are still big, averaging 2-3m long and weighing up to 3,600kg.
To see all five species of living rhino you would need to do a bit of exploring. First you might visit Africa for a look at the white rhino and the black rhino. They live in Africa’s dry woodlands and grasslands. Then you could head to India and Nepal for a look at the Indian rhino. It lives in the high grasslands near rivers, where you have to ride an elephant to find one. Finally you might travel to the rainforests on the islands of Indonesia to see the Sumatran and Javan rhinos. These are the smallest and rarest rhinos in the world and extremely difficult to find.
Most rhinos are gentle and timid (胆小的).They have a bad reputation for being very aggressive, but that may be partly because they get frightened easily. Also, they have poor eyesight. They rely on their strong sense of smell to tell them a stranger is approaching, but if the wind is blowing the wrong way, they may not know someone is there until it’s too late.
Rhinos can be found only in their habitats, which is why habitat destruction has caused rhino populations to decline. As they disappear from certain places, their absence leads to many changes to the landscape. For example, black rhinos in Africa only eat shrubs (灌木) and small trees, pruning (修剪) the plants and limiting their growth. Many other species benefit from this, and as rhinos disappear, so do many other animals sharing their habitat. Bushes and trees take over the land and force species like the antelope to leave in search of food. In a short time the whole habitat has changed.
【小题1】          From the text we learn that ______.

Two Christmas traditions have come under attack in recent years from environmentalists: Christmas cards and Christmas trees.

Paper cards are seen as wasteful and, for some people, going card-free is another way of going green. They also argue that in a world of e-mail, Skype, Facebook and Twitter, people are in touch all the time anyway; they no longer need the yearly card that connects them with long lost friends. If you want to send Christmas greetings, there are free e-cards, which get the job done with no postage or wasted paper.

However, especially for people who didn’t grow up with e-mail, there is something missing from a Christmas e-mail. The first Christmas cards appeared in London in 1843 and were designed by the same man who had introduced the world’s first postage stamp three years earlier. His name was Sir Henry Cole.

They rose in popularity throughout the 20th century. Many people sent cards that were sold for charity. The most famous of these are the ones sold for UNICEF. In the UK this year, in the three weeks before Christmas, the post office expects to handle 100 million cards every day. Environmental awareness also means that nowadays many people recycle their cards; this helps raise money to plant more trees, as well as recreating more paper.

When we think of trees at Christmas, there is one that immediately springs(跃入)mind---the evergreen tree that people decorate with ornaments and place their presents under. The custom dates back almost a thousand years to Germany. Nowadays 33 to 36 million Christmas trees are produced in America and 50 to 60 million in Europe each year. Some trees are sold live with roots and soil so people can plant them later and reuse them next year.

Some people prefer artificial trees as they are reusable and much cheaper than their natural alternative. However, environmentalists point out that they are made from petroleum (石油) products and so have many pollution issues.
