How to eat healthfully can be especially complex for working women who often have neither the desire nor the time to cook for themselves (or for anyone else). Registered dietitian(营养专家)Barhara Morrissey suggests that a few simple rules can help.

“Go for nutrient dense foods，” she suggests, “foods that contain a multiple of nutrients. For example, select whole wheat bread as a breakfast food, rather than coffee cake. Or drink orange juice rather than orange drink, which contains only a small percentage of real juice —the rest is largely coloured sugar water. You just can't compare the value of these foods, the nutrient dense ones are so superior，” she emphasizes.

Morrissey believes that variety is not only the spice of life—it's the foundation of a healthful diet. Diets which are based on one or two foods are not only virtually impossible to keep up the strength, they can be very harmful, she says, because nutrients aren't supplied in sufficient amounts or balance.

According to Morrissey, trying to find a diet that can cure your illnesses, or making you superwoman is a_fruitless_search. As women, many of us are too concerned with staying thin, she says, and we believe that vitamins are some kind of magic cure to replace food.

“We need carbohydrates, protein and fat — they are like the wood in the fireplace. The vitamins and minerals are like the match, the spark, for the fuel，” she explains. “We need them all, but in a very different proportions. And if the fuel isn't there, the spark is useless.”

“Drink your milk. It’s good for you!” You’ve probably heard that many times, and it’s true. Milk contains calcium, which is a necessary nutrient for keeping bones and teeth healthy and strong. The U.S. government even requires milk as part of the National School Lunch Program, saying that students should drink one cup of fat-free or low-fat milk at each meal.
Last Thursday, however, a group of doctors asked the government to remove milk from the lunch program. The Physicians Committee for Responsible Medicine (PCRM) says, “Milk is high in sugar, high in fat and high in animal protein, all of which have negative effects on health.” “One of the only reasons people talk about dairy, or promote it, is that it is going to help build strong bones.” says Dr. Neal Barnard, president of the PCRM. There are better and healthier ways to get calcium such as eating beans, broccoli, cereals and tofu. Orange juice and soymilk that have calcium added to them also supply the nutrient.
Of course, calcium is important for healthy bones and teeth, but your genes, how much vitamin D you take in and getting an hour’s worth of exercise every day all play a part.
Some nutritionists disagree with the idea that milk isn’t important. Keri Gans, a dietitian, says, “I think it’s irresponsible to take away this beverage that children enjoy, especially among those who are unable to meet their nutrient needs for the day, and remove it from the lunch line.”
The U.S. government is studying the request of the PCRM, but a decision may be a long way off. Meanwhile, Marion Nestle, a professor at New York University, puts it best: “Milk has nutrients. Other foods have the same nutrients. It’s just a food. Like other foods, too much might be a problem.”
【小题1】What is mainly talked about in the first paragraph?

A．The concern about students’ health.	B．Traditional attitudes towards milk.
C．Ways to keep bones and teeth healthy.	D．The practice of the U.S. government.

【小题2】According to Dr. Neal Barnard, milk is preferred mainly because _____.

A．children like its taste	B．people ignore its disadvantages
C．it contains more calcium than other foods	D．the calcium in it can build up bone strength

【小题3】We can learn from the text that _____.

A．bone strength is determined by many factors

B．people’s diets shouldn’t contain animal protein

C．the opinion of the PCRM will soon be accepted

D．people should turn to vegetables for calcium

Some plants get so hungry they eat flies, and even small frogs. What's more amazing is that these plants occur naturally (in special environments) in every state. In fact, they're found on every continent except Antarctica.

You've probably seen a Venus' flytrap -- a small plant, which grows 6 to 8 inches tall in a container. At the end of its stalks (茎) are leaves that act like traps (陷阱). Inside each trap is a lining of tiny hairs. When an insect lands on them, the traps suddenly shut. Over the course of a week or so, the plant feeds on its catch.

The Venus' flytrap is just one of more than 500 species of meat-eating plants, says Barry Meyers-Rice, the editor of the International Carnivorous Plant Society's Newsletter. He states although you might have read some science-fiction stories, no meat-eating plant does any danger to humans.

Barry says a plant is meat-eating, only if it does all four of the following: "attract, kill, digest, and absorb" some form of insects. Meat-eating plants look and act like other green plants -- well, most of the time.

All green plants make sugar to produce food. What makes meat-eating plants different is their special leaves, which need insects for one reason: nitrogen (氮). Nitrogen is a nutrient that they can't obtain any other way. Why?

Almost all green plants on our planet get nitrogen from the soil. Meat-eating plants can't. They live in places where nutrients are hard to get from the soil because of its acidity. So they've come to rely on getting nitrogen from insects and small animals. In fact, nutrient-rich soft is poisonous to meat-eating plants. Never fertilize (施肥) them! But don't worry, either, if they never seem to catch any insects. They can survive, but they'll grow very slowly.

1.According to the passage, a Venus' flytrap ______.

A．is a small plant which grows in a container

B．is a kind of plant which gets hungry easily

C．can trap and feed on some form of insects

D．can only grow 6-8 inches tall

2.From the passage, we can infer that ______.

A．meat-eating plants are found nowhere else except Antarctica

B．all green plants get nitrogen from the soil

C．meat-eating plants endanger humans in science-fiction stories

D．the nutrient-poor soil is beneficial to meat-eating plants

3.Meat-eating plants grow very slowly, ______.

A．so you'd better fertilize them

B．probably because the supply of nitrogen is cut off

C．simply because they can't absorb nitrogen from the soil

D．and then they will die slowly

4.Which of the following is true?

A．Meat-eating plants look and act like other green plants.

B．It's hard to get nutrients in the soil when acidity is high.

C．The Venus' flytrap eats flies to get nutrient from them.

D．Green plants make sugar at night.
