    We all know that certain oils are healthier than others,but your oil health goes beyond just the type.
The health of your oil can be related to how you use it too.
     Each type of oil has what is called a "smoke point". The smoke point is the specific temperature at
which the oil starts to break down,or in more technical terms,its molecular structure begins to change.
These molecular changes result in changes in flavor,as well as changes in nutritional value-specifically,
the nutritional value of the oil starts to reduce,changing what once may have been considered an
especially healthy oil,like olive,into one that is unhealthy.
     The higher an oil's smoke point is,the higher the temperature of the oil can be.As a result,each type
of oil should be used for the cooking method that is most appropriate to its individual smoke point and
heat tolerance.Here is a quick guide for the next time you reach for your favorite oil.

      Note that the above table represents oils that are refined (精炼的). Most oils we buy are refined.
     Refined oils tend to have much higher smoke points than when they are unrefined.They also differ in
nutrition and flavor.Unrefined oils are more nutritious and they tend to be much richer in flavor.
     When it comes to extremely high heat cooking,always choose oils which are refined.

       I had the meanest mother in the world. While other kids ate candy for breakfast, I had to have

cereal (谷类食物), eggs or toast. While others had Cokes and candy for lunch, I had to eat a

sandwich. As you can guess, my supper was different from other kids' too. But_at_least_I_wasn't

_alone_in_my_sufferings.   My sister and two brothers had the same mean mother as I did.

       My mother insisted upon knowing where we were at all times. She had to know who our friends

were and where we were going. She insisted if we said we'd be gone an hour, then we be gone one

hour or less-not one hour and one minute. And she always insisted upon us telling the truth. Now you

can see how mean she was.

     The worst is yet to come. We had to be in bed by nine each night and up at eight the next morning.

We had to wash dishes, make beds, and learn to cook. We had to wear clean clothes and take a bath,

while the other kids always wore their clothes for days. I believe she laid awake at night thinking up

mean things to do to us.

    Through the years, things didn't improve a bit. We could not lie in bed, "sick" like our friends did,

and miss school. Our marks in school had to be up to par(达到正常水平). Our friends' report cards

had beautiful colors on them, black for passing, red for failing. My mother, being as different as she

was, would settle for nothing less than ugly black marks.

      As the years rolled by, we were one by one put to shame. We were graduated from high school.

With our mother behind us, talking, hitting and demanding respect, none of us was allowed the pleasure

of being a dropout.

      My mother was a complete failure as a mother. Out of four children, a couple of us attained some

higher education. And whom do we have to blame for the terrible way we turned out? You're right,

our mean mother. She forced us to grow up into educated and honest adults.

      Now I am trying to raise my three children. I am filled with pride when my children call me mean.

Because, you see, I had the meanest mother in the world.
