    Starting the day on an egg could keep your blood pressure under control, research suggests. Scientists have shown that eggs produce proteins with a function similar to that of powerful blood pressure-lowering drugs.

    The research, from the University of Alberta in Canada, showed that when eggs come in contact with stomach enzymes (酶) they produce a protein that acts in the same way as Ace inhibitors, but more work is needed to show the effects outside a lab and in the human body.

    Earlier this month, British researchers declared that, contrary to popular beliefs, it is healthy to go to work on an egg. They concluded that the type of cholesterol (胆固醇) found in eggs has little effect on increasing heart disease risks.

    Researcher Professor Bruce Griffin, from the University of Surrey, said, "The wrong beliefs linking egg eating to high blood cholesterol and heart disease must be corrected. The amount of fat in our diet has an effect on blood cholesterol that is several times greater than the relatively small amounts of cholesterol found in eggs. The UK public do not need to be limiting the number of eggs they eat. They can be encouraged to include them in a healthy diet as they are one of nature's most nutritious foods."

    The British Heart Foundation dropped its three-egg-a-week limit in 2005. However, almost half of Britons believe the limit still applies.

(1)、From the text we know that Ace inhibitors are _____.
A、a kind of protein B、a kind of food C、a kind of medicine D、a kind of illness
(2)、According to what Professor Bruce said, eggs _____.
A、are the most nutritious food B、can be included in a healthy diet C、have no effect on blood cholesterol D、are forbidden to be eaten in the UK

    Across Britain, burnt toast will be served to mothers in bed  this morning as older sons and daughters to deliver their supermarket bunches of flowers, But, according to a new study, we should be placing a higher value on motherhood all year.

    Mothers have long known that their home worked was just heavy as paid work. Now, the new study has shown that if they were paid for their parental labors, they would earn as much as£172,000 a year.

    The study looked at the range of jobs mothers do, as well as the hours they are working, to determine the figure. This would make their yearly income £30, 000 more than the Prime Minister earns.

    By analyzing the numbers, it found the average mother works 119 hours a week,40 of which would usually be paid at a standard rate 79 hours as overtime. After questioning 1,000 mothers with children under 18,it found that ,on most days, mums started their routine work at 7am and finished at around 11pm.

    To calculate just how much mothers would earn from that labor, it suggested some of the roles that mums could take on, including housekeeper, part-time lawyer, personal trainer and entertainer. Being a part-time lawyer, at £48.98 an hour, would prove to be the most profitable of the “mum jibs”, with psychologist(心理学家)a close second.

    It also asked mothers about the challenges they face, with 80 percent making emotional(情感的)emand as the hardest thing about motherhood.

Over a third of mums felt they needed more training and around half said they missed going out with friends.

    The study shoes mothers matter all year long and not just on, Mother's Day. The emotional, physical and mental energy mothers devote to their children can be never-ending, but children are also sources of great joy and happiness. Investing(投入)in time for parenting and raising relationships is money well spent.

    As is known to us, Washington University in St. Louis became the first college in the United States to ban (禁止) selling bottled water in 2009. Since then, more than a dozen small colleges and schools have done the same. The ban isn't because the schools don't want students to have easy access to water. Instead, the goal is to encourage students to bring reusable bottles to save money and, more importantly, to save the environment.

    Many people believe that producing and using bottled water not only wastes money but also harms the environment. They say that bottled water is unnecessary because public water supplies in the U.S. are among the best in the world. These people believe that water fountains and reusable bottles with easy access to filling stations are a better choice.

    But the makers of bottled water argue that plastic bottles make up a small portion of the nation's total waste. They say it's unfair to single out (单独挑出) their product when so many other items are packaged in plastic containers, and what's more, water is a healthy choice compared to some sodas and juices that are also sold at school.

    What do you think: Should sales of bottled water be banned from schools? We want to hear your opinion. Write a 200-word response. Send it to tfkasks4you@timeforkids.com. Your response may be published in a future issue of Time For Kids. Please include your grade level and contact information for your parent or teacher if you want your response to be published. The deadline (截止时间) for responding is August 31, 2012.

    Doctors say you had better use it before you lose it. The more you sit each day, the more chance you have of getting sick.

    Richard Rosenkranz of Kansas State University was among the researchers. He said people who sat for long periods were at great risk of diseases when compared with those who sat less. He said that was especially true for some chronic (慢性的) diseases.

    Richard Rosenkranz studied the relationship between sitting and chronic diseases in middle-aged Australian men. He worked with researchers from the University of Western Sydney. They examined the health records of more than 63,000 men from New South Wales. The men were between the ages of 45 and 65. The men reported about what diseases they had, or did not have. And they kept record of the amount of time each day that they sat.

    The study also showed that exercising every morning for 30minutes did not reduce the health risk if you spend the next eight hours sitting at the desk. Mr. Rosenkranz said it was important to make sure you exercise. But he said it was also important to find ways not to sit so much during the day.

    Many jobs today require sitting and working at the desk all day. James Levine works at the Mayo Clinic in the United Sates. He suggests working while standing at high table some of the time instead of sitting at a desk. Dr. Levine also suggests standing while using the telephone or eating. Or he advises walking with the people you work with for an on-foot meeting. And he notes that if you spend more time on your feet, you may have muscle activity that helps burn fats and sugars in your body.

    What to do if you find a sick, injured or abandoned wild animal.

    General tips

    Don't remove an animal from its natural habitat (the animal may not need assistance, and you could do more harm than good).

    Check the animal periodically for 24-48 hours.

    Keep your distance.

    Young animals/babies

    If you find an abandoned young animal, separated from adults or left on its own — keep cats and dogs away and limit noise.

    An adult may not return if it is noisy or if people are close by.

    Get help for a wild animal

    In Ontario, wildlife rehabilitators (复健员) are authorized by the Ministry of Natural Resources and Forestry to provide temporary care to sick, injured and abandoned wildlife so it can be returned to the wild. Rehabilitators commit significant time and resources, and many seek donations to assist with their work.

    Every effort is made by wildlife rehabilitators to ensure wildlife in their care do not become tame (驯服).

    Find a wildlife rehabilitator

    To get help for a sick, injured or abandoned animal, you can contact: an authorized wildlife rehabilitator your local Ministry of Natural Resources and Forestry district office

    Health risks

    If you come across sick or diseased wildlife and you suspect there is a public health risk (such as West Nile virus), contact your regional or local health unit immediately: Ontario Public Health Units

    Public safety

    If the animal is alive and there is a public safety issue, contact your local police department.
