必修3 Unit 2 Healthy eating健康膳食晨读·记忆Balanced DietWang Peng earned his living by running a barbecue restaurant, which served delicious bacon, fried chicken breast and mutton roasted with pepper and garlic. But his food and discount attracted fewer and fewer customers. Finally, he was in debt. Yong Hui’s slimming restaurant served fresh peas, carrots, eggplants, and raw cucumbers with vinegar. As the hostess, she said fibres benefited customers' digestion most. In order not to let Yong Hui get away with tellinglies, Wang Peng spied on Yong Hui despite her glare. But he was surprised that she was losing her customers, too.Curiosity drove Wang Peng to consult an expert. The expert sighed and said, “Both of your menus have weakness and limited strength.

(2020·广西重点高中模拟)People love cellphones, which is why nine in ten Americans own one.But does heavy use of cellphones pose a risk of cancer? This question has caused controversy for many years. A new study in rats now augments those concerns.Its data linked long­term, intense exposure to radiation from cellphones with an increased risk of cancer in the heart or brain.The results have yet to be confirmed, the authors note.Indeed, although the rat study found a link between cellphone radiation and cancer, it offers no clues to why such a link might exist, notes Jonathan Samet.He teaches preventative medicine and directs the Institute for Global Health at the University of Southern California in Los Angeles.Still, he calls the new study’s findings “signi ficant”．They could lead to studies researching how cellphone radiation might cause cancer, he says.Phone signals are relayed between cell towers and cellphones via radio waves.This radio frequency—or RF—radiation is a type known as non­ionizing(非电离的). Unlike X­rays, non­ionizing radiation does not deposit enough energy into cells to release electrons from atoms or molecules, producing ions.So it tends to be far less harmful than ionizing radiation, such as X­rays.But that does not mean radio waves might not cause harm.In very large doses(量) this radiation will heat the body and cause tissue damage.But it’s not yet known what much lower RF levels might do, such as thosefrom cellphone use.Five years ago, the World Health Organization’s International Agency for Research on Cancer, or IARC, concluded that cellphone use “is possibly carcinogenic(致癌的)”．Its conclusion was based on what little research data was available at that time.But notice that IARC was not certain.It said only that phone use might “possibly” cause cancer.So scientists at the National Toxicology Program, or NTP, investigated further.【解题导语】本文是一篇说明文。
