  [1]Cooking carrots whole before chopping them up increases their anti-cancer properties by 25 percent, researchers say.

  [2]Leaving the vegetable intact(完整的)prevents valuable nutrients from being easily washed away into water.They can then be chopped up once cooked without loss of nutrients.

  [3]Carrots have long been prized for their health benefits, especially their vitamin and fiber content.They contain huge amounts of carotenoids(类胡萝卜素)which are converted into vitamin A in the body.They are also an excellent source of the anti-cancer compound falcarion(镰叶芹醇).In a previous study, Dr Kirsten Brandt found rats fed on a diet containing carrots or isolated falcarino were less likely to develop tumors than those which were not.

  [4]They also found that carrots boiled before they were cut contained 25 percent more falcarino than those that were chopped up first.Carrots which are cut have a higher surface area in contact with water, resulting in greater loss of nutrients, compared with boiling them whole.The heat softens the cell walls in the vegetable, allowing vitamins and falcarino to leach(过滤)out.

  [5]Dr Brandt said, "The great thing about this is that it's a simple way for people to increase their uptake of a compound, which is good for you.All you need is a bigger saucepan.Naturally occurring sugars, responsible for giving the carrots its sweet flavor, were also found in higher concentration in carrots that had been cooked whole."

  [6]The team also carried out a taste on almost 100 volunteers comparing carrots boiled before being cut and some that are cut up first.More than 80 percent of volunteers said that carrots cooked whole tasted much better.

  [7]Boiling carrots whole appears to help them keep more of the nutrients.This is really a piece of good news because the method is of great value.Some other vegetables, such as parsnips(欧洲萝卜)which are from the same family and have a roughly similar size and texture can also be more nutritious by _________.

[1]One Friday night in May 2010, Oliver and Ione Kleven heard angry shouts coming from their front lawn(草坪). Ione, 65, stepped onto the porch(门廊) and saw two men in dark clothes struggling with something on the ground—right where she and her grandson had planted a flower bed the weekend before.

[2] “Go fight somewhere else!” she shouted, worried her plants would get damaged. At the sound of her voice, the face of a boy appeared from beneath the two men. He looked 14. “They’re trying to kill me!” the boy screamed. Ione ran toward them and, without hesitation, caught the boy’s arm, pulling him out.

[3] “Leave him alone!” she shouted. When the men stood up, Ione saw what looked like a sharp object in one man’s hand. When she turned back toward the boy, he was moaning(呻吟) in pain and holding his stomach. The attackers began to move in on the boy again when Ione’s husband shouted: “Get lost!” The two men walked quickly and quietly across the street and drove off in a dark car.

[4]“I have to get to the hospital!” the boy cried. He lifted his shirt, and Ione could see a bloody wound on his stomach. Oliver hugged the trembling(发抖的) boy while Ione caught her cell phone and car keys inside the house. She handed the phone to Oliver. “Call 911,” she told him. “I’m going after them.” Ione took off but was unable to find the car.

[5]The Klevens then learned what had happened . Earlier that night, as the boy waited for his parents to pick him up from the high school across the street from the Klevens’ house, two men approached and demanded his wallet. When he refused, one of the men hit him in the face. The boy ran across the street. The men caught up with him, and one hurt him in the back and stomach with a sharp knife. That’s when Ione stepped in.
