  When the Audet family turns on the lights at Blue Farm, they are using electricity that comes from cows-cow manure(粪肥), to be specific.

  Cows produce a lot of wastes.One cow can create 30 gallons of wastes each day.Now imagine the output of over 1, 000 cows at Blue Farm.That’s really a big amount.

  When farmers clean their barns, they put the wastes in a big heap, and spread some of them on their fields for fertilizer(肥料).But now places like Blue Spruce Farm have a new way of using cow wastes.They use them to produce electricity.

  Here’s how it works:A big machine moves back and forth cleaning the barn floor.“The cows aren’t bothered,” says Marie Audet.“They are animals of habit; they get used to it, and just lift one foot and then another to let it go by.”

  The machine pushes the manure into a big 600-gallon tank like a small swimming pool.The tank is called a digester(化粪池)because what happens there is just like what happens inside a cow:Bacteria(细菌)get to work and continue to digest the manure.

  Methane gas(甲烷、沼气)in the atmosphere is known as a “greenhouse” gas because it keeps heat just like a greenhouse does, causing our planet to warm up.That’s an environmental concern.But the digester has a good result.Its gas is kept and used to power electric generators(发电机).

  At Blue Farm, the generators make enough electricity to power 400 homes.The Audet family sells the extra electricity they can’t use themselves.

阅读下面短文,并根据短文内容从各题所给的A、B、C、D四个选项中,选出一个最佳选项。

  People believed for a long time that the heart was the center of a person's emotions.That is why the word heart is used in so many expressions.

  One such expression is to "lose your heart" to someone.When that happens, you have fallen in love.But if the person who "won your heart" does not love you, then you are sure to have a "broken heart." You may think that the person you loved is "hard-hearted, " and in fact, has a "heart of stone."

  You may decide to "pour out your heart" to a friend.Telling someone about your personal problems can often make you feel better.

  If your friend does not seem to understand how painful your broken heart is, you may ask her to "have a heart." Your friend "has her heart in the right place" if she says she is sorry, and shows great concern(关心)for how you feel.

  When you are worried, your "heart is in your mouth." You might say, for example, that your heart was in your mouth when you asked a bank to lend you some money to pay for a new house.

  If that bank says no to you, do not "lose heart." Be "strong-hearted." Sit down with the banker and have a "heart to heart" talk.The bank may have a "change of heart." It may agree to lend you the money.Then you could stop worrying and "put your heart at rest."

Stress Level Tied to Education Level

  People with less education suffer fewer stressful days, according to a report in the current issue of the Journal of Health and Social Behavior.

  However, the study also found that when less-educated people did suffer stress it was more severe and had a larger impact on their health.

  From this, researchers have concluded that the day-to-day factors that cause stress are not random.Where you are in society determines the kinds of problems that you have each day, and how well you will cope with them.

  The research team interviewed a national sample of 1,031 adults daily for eight days about their stress level and health.People without a high school diploma(毕业文凭)reported stress on 30 percent of the study days, people with a high school degree reported stress 38 percent of the time, and people with college degrees reported stress 44 percent to the time.

  “Less advantaged people are less healthy on a daily basis and are more likely to have downward turns in their health,” lead researcher Dr.Joseph Grzywacz, of Wake Forest University Baptist Medical Center, said in a prepared statement.“The downward turns in health were connected with daily stressors and the effect of daily stressors on their health is much more devastating(毁灭性的)for the less advantaged.”Grzywacz suggested follow-up research to determine why less-educated people report fewer days of stress when it is known their stress in more acute and chronic.

  “If something happens every day, maybe it’s not seen as a stressor” Grzywacz says.“Maybe it is just life.”
