Over the past century, all kinds of unfairness and discrimination have been condemned or made illegal. But one insidious form continues to thrive: alphabetism. This, for those as yet unaware of such a disadvantage, refers to discrimination against those whose surnames begin with a letter in the lower half of the alphabet. It has long been known that a taxi firm called AAAA cars has a big advantage over Zodiac cars when customers thumb through their phone directories. Less well known is the advantage that Adam Abbott has in life over Zoe Zysman. English names are fairly evenly spread between the halves of the alphabet. Yet a suspiciously large number of top people have surnames beginning with letters between A and K. Thus the American president and vice president have surnames starting with B and C respectively; and 26 of George Bush’s predecessors (including his father) had surnames in the first half of the alphabet against just 16 in the second half.

Mother Nature Shows Her Strength
Tornadoes（龙卷风）and heavy thunderstorms moved across the Great Lakes and into
Trumbull County on Saturday evening.The storms were dramatic and dangerous.
George Snyder was driving the fire truck down Route 88 when he first noticed that a
funnel（漏斗状的）cloud was behind him. " I stopped the truck and watched the funnel
cloud.It was about 1 00 feet off the ground and I saw it go up and down for a while.It was
moving toward Bradley Road and then suddenly it disappeared,"Snyder said.
Snyder only saw one of the funnel clouds that passed through northeastern Ohio on
Saturday.In Trumbull County,a tornado turned trees onto their sides.Some trees fell onto
houses and cars.Other trees fell into telephone and electrical wires as they went down.
Amanda Symcheck was having a party when the storm began."I knew something was
wrong , " she said."I saw the sky go green and pink（粉红色）.Then it sounded like a
train rushing toward the house.I started crying and told everyone to go to the basement for
protection."
The tornado caused a lot of damage to cars and houses in the area.It will take a long
time and much money to repair everything.There was also serious water damage from the
thunderstorms.The heavy rains and high wind caused the power to go out in many homes.
The storms caused serious flooding in areas near the river. More than four inches of
rain fell in parts of Trumbull County.The river was so high that the water ran into streets
and houses.Many streets had to be closed to cars and trucks because of the high water.
This made it difficult for fire trucks,police cars,and other rescue vehicles to help people
who were in trouble.
Many people who live near the river had to leave their own safety.
Some people reported five feet of water in their homes.Local and state officials opened
emergency shelters for the people who were evacuated(撤走).The Red Cross served meals to them.
"This was a really intense storm,"said Snyder."People were afraid.Mother Nature can be fierce.We were lucky this time.No one was killed."
Power supply system was not damaged during the storm.
A.Right
B.Wrong
C.Not mentioned
