In France,there once lived a man named Louis Pasteur,who was a doctor of science.The thing (17) occupied his mind was the disease rabies.

"I must find the rabies germs that hide inside people and make them so sick (18) they die,"he thought. "Once I find that invisible enemy,I'll think of a way to kill it.I just know I (19) do it."

Many people thought Pasteur was wasting his time.Some laughed at him and said,"You'll never do it.No one can find (20) invisible enemy!"

Pasteur didn't care (21) people thought,he believed in (22) .He kept right on working.

Meanwhile,in German,a boy named Joey was about to get into trouble.He wasn't a bad boy,he was just thoughtless,as children sometimes are.He was playing with a dog.But this dog was sick with rabies,(23) made the dog mad.

When Joey got tired of playing with the dog,he started to go home.Unfortunately,the dog escaped from behind the fence and bit Joey.

The invisible enemy—the rabies germs—were passed on from the dog to Joey.

Soon the little boy was very sick.Everyone knew that if someone was bitten by a sick,mad dog,that person would become infected with rabies and die.His parents could only wait.

But then there was news.Joey's mother saw it and shouted for joy."A doctor of science (24) (find) a way to save people like Joey!"she said."He says sick people like Joey have been infected by an invisible enemy,and he's found a way to kill it!"

The man,of course,was Louis Pasteur.He had done what he had set out to do.

Joey's parents quickly prepared Joey (25) the long journey to Paris.

"Dr.Pasteur,"said the mother upon their arrival at Pasteur's residence,"we've come a long way.Our little boy (26) (bite) by a mad dog,and he's very sick.Can you help us?"

"Perhaps,"said Pasteur."I've invented a vaccine（疫苗）.It is strong enough to kill the invisible enemy.

Joey was finally saved and later became a gatekeeper at the Pasteur Institute.

You've probably heard of the list of factors that put you at risk for heart disease: smoking,poor diet,lack of_27_ and so on.But did you know that the health of your gums（牙龈）may also affect your chance of_28_heart disease?

More than 120 studies have investigated the_29_link between gum disease and heart disease.Most of them say that gum disease is a risk factor for heart disease and other diseases that affect blood vessels.This means that people with gum disease often develop heart disease but that gum disease doesn't_30_cause heart disease.

Doctors and scientists have proposed a number of possible reasons for this connection.One common factor is inflammation（发炎）,which occurs when the body senses a_31_and sends white blood cells to attack it.This leads to painful swelling（肿胀）,which is the main symptom of gum disease.White inflammation hasn't been shown to cause heart disease,it often accompanies it.And as it turns out,the same types of bacteria often lead to inflammation in both diseases.

It's also possible that the_32_has less to do with biology than with an individual's habits.Perhaps people who take good care of their teeth make other healthy choices that prevent heart disease.

So what does this mean for your health?Since the role of gum disease in causing heart disease isn't_33_,don't take it for granted that taking care of your teeth will protect your heart.Certainly,brushing and cleaning are not replacement for exercise and a_34_diet.But keeping your mouth healthy and avoiding gum disease are still good goals to go after.They'll spare you pain and high dental bills and keep your bright smile complete.

This research does mean that if you have gum disease,you should get your heart_35_this is especially true if you are at risk of heart disease for other reason,such as smoking.

Who would have thought that your mouth and your heart would be connected?The body is a complex and mysterious thing,so do all you can to_36_it.
