Stomach Ulcer

Stomach ulcers are the cause of severe pain for many people.Doctors have been able to help lessen the
pain of ulcers.They could not cure them.Now doctors have discovered a cause of ulcers.This means they
may have found a way to cure people who suffer from the stomach pain.Studies show that ten percent of the
population will develop an ulcer at some time in their lives.So a possible cure is good news for many people.
Ulcers are wounds in the stomach that are similar to small cuts or tears.These wounds can harm the
tissue in the stomach,the pipe that carries the food to the stomach or parts of the small intestines.Fluids in
the stomach then increase the pain of an ulcer. How does a person know he or she has an ulcer? Doctors say
most people with ulcers feel a burning pain in their chests or stomachs.This pain is often called heartburn.It
usually happens before eating or during the night. It causes some people to lose their desire to eat,or they are
unable to keep food in their stomachs.Doctors believed that ulcers were caused by unusually strong stomach
fluids,which damaged stomach tissue.Now they have discovered that most ulcers are caused by a bacterial
organism called Hillico Bactor Pilorie or H Pilorie.H Pilorie bacteria are what make stomach produce extra
stomach fluid.Doctors found that they can kill the bacteria with medicines called antibiotics.Health experts
say the discovery of a cure for ulcers can save thousands of millions of dollars in medical costs.They also
believe curing ulcers will reduce the number of people who develop stomach cancer. The number of people
with stomach cancer is very high in Japan,Southeast Asia and parts of Africa.
Doctors say a person is more likely to get an ulcer if someone in his or her family has had one.In fact a
person with the family history of ulcers is three times more likely to get one than other people.There are ways
people can protect themselves from developing an ulcer. Doctors say it is more important to reduce the amount
of strong fluids in the stomach.To do this,doctors say,people should not smoke cigarettes or drink alcohol.
And they say people should reduce tension in their lives.

Doctors have discovered a cause of ulcers after many years of experiments.
A:Right
B:Wrong

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."

Rescue vehicles had a hard time getting to people.
A:Right
B:Wrong
C:Not mentioned
