18.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.(36)ACertain 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.(37)CSome people think that as long as you brush your teeth,you shouldn't have bad breath. (38)EThat,however,just doesn't remove the smell.To sufficiently clean all the surfaces of your teeth,you should brush for at least 2minutes 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!(39)G3When 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.(40)BThey 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 30to 45seconds.
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.
5.Music is magic!Music speaks louder than words and it is a"language"that the whole world can understand.A piece of music can produce a response in the heart and mind.Like feeling an electrical current or receiving a personal radio signal,music has a spiritual effect on a person.Different kinds of music influence people in different ways.
I have listened to music all my life.When I was twelve years old,the Beatles came to America and my whole world opened up.Maybe young people today cannot understand the influence of the Beatles when they exploded across America.Their influence changed the way we dressed,looked,acted and spoke…even our culture.The Beatles arrived in America from the UK just under three months after the assassination(暗杀) of President John Kennedy,which had put America into a great depression.And the freshness and lively spirit of the Beatles was exactly what the country needed to refresh itself.
Music links the heart of the hearer with that of the composer.This means that it mixes the spirit of the composer with your spirit when you listen to it.And the music can take your spirit out of your body and transport you into another world.Music has a great way of touching people.Music can make you laugh,cry or shout.It's also a great source of inspiration.
Try this one day and notice what happens:make yourself a cup of tea,sit on your sofa and play one of your favorite songs.Close your eyes,and soon you'll find yourself creating vivid mental images-matching the music that you are listening to.

19.Hundreds of years ago,a Roman army came north from England to make war on Scotland.The Scots,a brave people,loved their country very much.They fought hard to drive the enemy out of Scotland,but there were too many Romans.It looked as if the Romans would win.
One night,the leader of Scots marched his soldiers to the top of a hill."We will rest here tonight,my men,"he said."Tomorrow we will fight one more battle.We must win or we will die."
They were all very tired,so they ate their supper quickly and fell asleep.There were four guards on duty,but they,too,were very tired,and one by one,also fell asleep.
The Romans were not asleep.Quickly they gathered at the foot of the hill.Slowly they climbed up the hillside,taking care not to make a sound.Closer and closer they came to the sleeping Scots.They were almost at the top.A few minutes more,the war would be over.Suddenly,one of them put his foot on a thistle(蓟).He cried out and his sudden cry woke the Scots.In a moment,they were on their feet and ready for battle.The fighting was hard but it did not last long.The Scots wiped out the Romans and saved their country.
The thistle is not a beautiful plant.It has sharp needles all over it.Few people like it.But the people of Scotland liked it so much that they made it their national flower.

20.Arriving in Sydney on his own from India,my husband,Rashid,stayed in a hotel for a short time while  looking for a house for me and our children.
During the first week of his stay,he went out one day to do some shopping.He came back in the late afternoon to discover that his suitcase was gone.He was extremely worried as the suitcase had all his important papers,including his passport.
He reported the case to the police and then sat there,lost and lonely in a strange city,thinking of the terrible troubles of getting all the paperwork organized again from a distant country while trying to settle down in a new one.
Late in the evening,the phone rang.It was a stranger.He was trying to pronounce my husband's name and was asking him a lot of questions.Then he said they had found a pile of papers in their trash can(垃圾桶) that had been left out on the footpath.
My husband rushed to their home to find a kind family holding all his papers and documents.Their young daughter had gone to the trash can and found a pile of unfamiliar papers.Her parents had carefully sorted them out,although they had found mainly foreign addresses on most of the documents.At last they had seen a halfwritten letter in the pile in which my husband had given his new telephone number to a friend.
That family not only restored the important documents to us that day but also restored our faith and trust in people.We still remember their kindness and often send a warm wish their way.
