Bad breath can be a major problem. The good news is that it can often be prevented with some simple steps.
Bad breath is caused by certain bacteria that grow in the mouth. When you don't brush regularly, bacteria accumulate in your mouth and between your teeth. 1. Certain foods, especially ones like garlic and onions that contain pungent (辛辣的)oils, can contribute to bad breath because the oils are carried to your lungs and out through your mouth. 2. Some people think that as long as you brush your teeth, you shouldn't have bad breath. 3. That, however, just doesn't remove the smell. To sufficiently clean all the surfaces of your teeth, you should brush for at least 2 minutes at least twice a day.
Many people believe that if you breathe into your hand, you'll know when you have bad breath. But it’s wrong! 4. When you talk, you tend to bring out the smell from the back of your mouth (where bad breath starts), which simply breathing doesn't do. Also, because we tend to get used to our own smells, it's hard for a person to tell if he or she has bad breath.
If you’re concerned about bad breath, make sure you’re taking care of your teeth and mouth properly. If you brush properly and visit your dentist for regular cleanings but your bad breath persists, you may have a medical problem. 5. They can figure out if something else is behind your bad breath and help you take care of it.
A. These bacteria make your breath smell.
B. In that case, call your doctor or dentist.
C. Smoking is also a major cause of bad breath.
D. Remember to brush your tongue, too — bacteria love to hang out there.
E. The truth is that most people only brush their teeth for 30 to 45 seconds.
F. When you breathe, the smell bounced back by your hand can be easily sensed.
G. When you breathe, you don^ use your throat the same way you do when you talk.

Going green seems to be fad (时尚)for a lot of people these days. Whether that is good or bad, we can’t really say, but for the two of us, going green is not a fad but a lifestyle.
On April 22, 2011, we decided to go green every single day for an entire year. This meant doing 365 different green things, and it also meant challenging ourselves to go green beyond easy things. Rather than recycle and reduce our energy, we had to think of 365 different green things to do and this was no easy task.
With the idea of going green every single day for a year, Our Green Year started. My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all the green things that could be done to help the environment. We wanted to push the message that every little bit helps.
Over the course of Our Green Year, we completely changed our lifestyle. We now shop at organic(有机的)stores. We consume less meat, choosing green food. We have greatly reduced our buying we don’t need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made fresh bread. In our home office anyone caught doing something ungreen might be punished.
Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planet.

Tourism can be both good and bad. Yes, it brings in money for the local economy and creates lots of jobs for locals.1.
One growing problem is tourists who want to prove that they have visited a destination. They have used paints, rocks, or even keys to write on the Luxor Temple in Egypt, the Colosseum in Rome, Stonehenge in the UK, and many, many other places. 2.
Another big problem in some places has been tourists disturbing (打扰) the local people and life. Some tourists walk around and take pictures of local people without asking for their permission(准许). For example, Chiang Mai University in Thailand and Yonsei University in South Korea have great numbers of tourists visiting their campuses and walking through their libraries, taking pictures of students, and disturbing their studies. 3. Some tourists love to party there late into the night, making it difficult for locals to sleep.
4.Walking in large groups without considering others who need to walk by, crossing roads without thinking of local traffic laws, and many more, can be seen everywhere.
The only way to solve the problem of terrible tourists is to make sure that you are not one ! 5. Remember, whenever you step out of your country, you are representing (代表) your country to the rest of the world.
A. But it may also bring some problems.
B. Pass kindness along to future generations.
C. Thousands of tourist sites are being destroyed.
D. Be the best, kindest, most polite tourist possible.
E. The number of problems from tourists is endless.
