Brushing your teeth twice a day should keep the dentist away.But if a group of scientific researchers
have their wish,it will make the rest of your body healthy too. _________(46)It is one of many gadgets（小
装置）proposed by engineers and doctors at the Center for Future Health in New York—others include a pair
of glasses that help to jog your memory,and a home camera designed to check for cancer.
The devices seem fanciful,but the basic principles are simple.The gadgets should make it easy for peo-
pie to detect illness long before it strikes and so seek treatment far earlier than normal.________(47)In the
long run,the technology may even prevent illness by encouraging us to lead healthier lives.
Intelligent bandages（绷带）are a good example. Powerful sensors within the bandage could quickly
identify tiny amounts of bacteria in a wound and determine which antibiotics（抗生素）would work best.
___________(48)
Socks are long overdue for makeover. In the future they will be able to automatically detect the amount
of pressure in your foot and alert you when an ulcer（溃疡）is coming up.
All the projects should have far-reaching implications,but the biggest single development is a melanoma
（黑瘤）monitor designed to give early warnings of cancer._________(49)If a problem is found,the system
would advise you to get a check-up at your doctor's surgery.
If all this sounds troublesome,then help is at hand._________(50)A standard computer would be able
to understand your voice and answer questions about your symptoms in plain English and in a way which
would calm your nerves.

__________（49）
A:The device could be used to take a picture of your body each week,then compare it with previous images.
B:That is going to be the difficult part.
C:The cut could then be treated instantly,so avoiding possible complications.
D:Experts are also working on a "digital doctor" ,complete with a comforting bedside manner.
E: Instead of relying on hi-tech hospitals,the emphasis is shifted to the home and easy-to-use gadgets.
F:A toothbrush that checks blood sugar and bacteria while you brush is currently in development in USA.

Germs are everywhere. You can′t see them, but they are on your desk, on your computer, and even in the air!
Like people, germs move around the world. They fly with us on planes. When food, clothes, and other things travel around the world, germs travel, too. Some germs are safe, but some are dangerous. Germs cause illnesses like colds and the flu.
Warmer Weather Brings Germs
The world′s weather is changing. Cooler countries are getting warmer, so insects from hot countries can move there. Some of these insects, like mosquitoes, carry dangerous germs. These germs cause headaches, fever, and can even kill people.
Under Your Skin
Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too. They enter your body when you touch your eyes, nose, or mouth.
Your immune system (免疫系统) protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells (细胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies. Antibodies help your body find and stop germs.
What can you do to fight germs? You should wash your hands with soap and water. Soap kills many germs, and water washes them away.
What do antibodies do?

Energize Yourself and Your Family

Being healthy and active can help give you the energy to keep up with the demands of your busy life,take better care of yourseff,and be there for the people who depend on you.
If you are overweight and inactive,you are more likely to get Type 2 diabetes,heart disease, high blood pressure,stroke and certain forms of cancer. You may improve your health if you move more and eat better!Here are some tips on how to get moving and eat well even when your life is busy.
Try to do at least 30 minutes of moderate-intensity physical activity (like brisk walking) on most days of the week.It is not as hard as you may think,and you do not have to do the whole 30 minutes at one time.Give up the typical excuse such as"I don't have time for physical activity". You can"sneak"it into your day,a few minutes at a time.Get started by making small changes in your daily routine,for example,get off the bus or subway one stop early and walk the rest of the way. You do not have to do your entire workout in one block of time.Break it up一taking three 10- minute walks during your day may be easier than taking one 30-minute walk.
Physical activities do not have to be chores.You can make them fun.Do things you enjoy,like walking,dancing,swimming,or playing sports.Walk or take an exercise class with a friend or a group.Be active with your kids-ride bikes or toss a softball.
It may be hard to eat healthy if you do not have time to cook or your kids want fast food.Here are some ways that you and your family can eat better. Eat breakfast every day.Try a whole-grain cereal like raisin bran with fat-free or low-fat milk,or whole-wheat toast spread with jam. Enjoy some fruit with your breakfast too.Teach kids that healthy foods taste good.Choose fat-free or low-fat milk,yogurt,and cheese instead of full-fat dairy products.Choose whole-grain foods like whole-wheat bread,oatmeal,and brown rice more often than refined-grain foods,like white bread and white rice.Snack on fruits and vegetables. Keep a bowl of fruit on the table,bags of mini carrots in the refrigerator,and boxes of raisins in the cupboard.Do not keep a lot of sweets like cookies,candy,or soda in the house.
Set goals.Move at your own pace.Celebrate your successes.Allow for setbacks.Let your family and friends help you.And keep trying一you can do it!

Healthy foods do not taste good.

The human body is truly amazing. It allows us to sense the world around us,to do work and have fun,
and to move from place to place.In fact,the human body does its work so well that most people don't think
about it very much一until they get sick.
The germs（致病菌）that make people sick are everywhere. You can ' t see them , but they ' re there.
They're sitting on your desk.They're hiding on your computer's keyboard.They're even in the air that you
are breathing. There are two types of germs : viruses and bacteria（细菌）.Viruses are germs that can only
live inside animals or plants. Viruses cause illnesses such as flu and measles（麻疹）.Bacteria are tiny
creatures.Some bacteria are good.They can help your stomach break down food.Other bacteria aren't so
good. They can make you sick. Bacteria can cause sore throats（喉痛）and ear infections.
How can you stop these tiny invaders from making you sick?Your skin is the first defense against
germs.You can prevent some illnesses simply by washing,with soap and water. But germs can still enter the
body through small cuts in the skin or through the mouth,eyes,and nose.
Once germs are inside your body, your immune（免疫的）system tries to protect you. It looks for and
destroys germs.How does it do that?Special cells patrol your body.Some of these cells actually eat germs!
Other cells make antibodies.An antibody sticks to a germ.There is a different antibody for each kind of
germ. Some antibodies keep germs from making you sick.Others help your body find and kill germs.After a
germ is destroyed,the antibodies stay in your body.They protect you if the same kind of germ comes back.
That way you will not get the same illness twice.
You can keep your body healthy by eating a nutritious（有营养的）diet to make your immune system
strong. You can also help your immune system fight germs by getting vaccinated（接种）.Vaccines are
medicines.They contain germs that have been killed or weakened.The dead germs can't make you sick.
Instead,they cause your body to make antibodies.If the same germ ever shows up again,then your
antibodies attack it.

After they kill germs,antibodies stay in the body.

If you are overweight and inactive,you are more likely to get Type 2 diabetes,heart disease, high blood pressure,stroke and certain forms of cancer. You may improve your health if you move more and eat better!Here are some tips on how to get moving and eat well even when your life is busy.
Try to do at least 30 minutes of moderate-intensity physical activity (like brisk walking) on most days of the week.It is not as hard as you may think,and you do not have to do the whole 30 minutes at one time.Give up the typical excuse such as"I don't have time for physical activity". You can"sneak"it into your day,a few minutes at a time.Get started by making small changes in your daily routine,for example,get off the bus or subway one stop early and walk the rest of the way. You do not have to do your entire workout in one block of time.Break it up一taking three 10- minute walks during your day may be easier than taking one 30-minute walk.
Physical activities do not have to be chores.You can make them fun.Do things you enjoy,like walking,dancing,swimming,or playing sports.Walk or take an exercise class with a friend or a group.Be active with your kids-ride bikes or toss a softball.
It may be hard to eat healthy if you do not have time to cook or your kids want fast food.Here are some ways that you and your family can eat better. Eat breakfast every day.Try a whole-grain cereal like raisin bran with fat-free or low-fat milk,or whole-wheat toast spread with jam. Enjoy some fruit with your breakfast too.Teach kids that healthy foods taste good.Choose fat-free or low-fat milk,yogurt,and cheese instead of full-fat dairy products.Choose whole-grain foods like whole-wheat bread,oatmeal,and brown rice more often than refined-grain foods,like white bread and white rice.Snack on fruits and vegetables. Keep a bowl of fruit on the table,bags of mini carrots in the refrigerator,and boxes of raisins in the cupboard.Do not keep a lot of sweets like cookies,candy,or soda in the house.
Set goals.Move at your own pace.Celebrate your successes.Allow for setbacks.Let your family and friends help you.And keep trying一you can do it!

A Doctor in the House

Brushing your teeth twice a day should keep the dentist away.But if a group of scientific researchers
have their wish,it will make the rest of your body healthy too._________ (46)It is one of many gadgets
（小装置）proposed by engineers and doctors at the Center for Future Health in New York一others include a
pair of glasses that help to jog your memory,and a home camera designed to check for cancer.
The devices seem fanciful,but the basic principles are simple.The gadgets should make it easy for peo-
pie to detect illness long before it strikes and so seek treatment far earlier than normal.______(47)In
the long run,the technology may even prevent illness by encouraging us to lead healthier lives.
Intelligent bandages（绷带）are a good example. Powerful sensors within the bandage could quickly
identify tiny amounts of bacteria in a wound and determine which antibiotics（抗生素）would work best.
_________(48)
Socks are long overdue for a makeover. In the future they will be able to automatically detect the amount
of pressure in your foot and alert you when an ulcer（溃疡）is coming up.
All the projects should have far-reaching implications,but the biggest single development is a melanoma
（黑瘤）monitor designed to give early warnings of cancer.__________(49)If a problem is found,the sys-
tern would advise you to get a check-up at your doctor's surgery.
If all this sounds troublesome,then help is at hand.________ (50)A standard computer would be
able to understand your voice and answer questions about your symptoms in plain English and in a way which
would calm your nerves.

_________（46）
A:Experts are also working on a"digital doctor",complete with a comforting bedside manner.
B: Instead of relying on hi-tech hospitals,the emphasis is shifted to the home and easy-to-use gadgets.
C:The cut could then be treated instantly,so avoiding possible complications.
D:That is going to be the difficult part.
E:The device could be used to take a picture of your body each week,then compare it with previous images.
F:A toothbni,h that checks blood sugar and bacteria while you brush is currently in development in USA.
