Take good care of our teeth
When people take your picture, they say: “Say cheese! Smile!” So you do—you open your mouth and show your teeth. Healthy teeth help you to look your best. Do you know how to take care of them
Brush your teeth
Long ago, when people got older, their teeth would rot away. Rotting teeth give people toothache. To avoid a toothache, people pulled the bad tooth out. Finally they learned that cleaning their teeth was important. But they didn’t have toothpaste then. They tried things such as chalk and lemon juice.
About 100 years ago, someone finally made a paste to clean teeth. Not long after that, someone invented the toothpaste tube. That way people could put the paste right onto the toothbrush.
Tooth brushing became popular during World War II. The US Army gave brushes and toothpaste to all soldiers. They learned to brush twice a day.
Today there are all kinds of toothpastes. Toothpastes come in different colors and flavors. When you choose your toothpaste, make sure it has fluoride. Fluoride makes your teeth strong.
Use floss
Sometimes your teeth need deeper cleaning than brushing. That is when floss is helpful. You pull it between your teeth, and it reaches places where your toothbrush can’t go. Floss can pull out food that is between your teeth.

If only I had followed Mom’s advice
The major theme of my summer this year has been “going back home”. I went back to China as soon as school was over, at the end of June. I returned to Canada on August 17.
Going back to China this summer was not easy, because of the A (H1N1) flu. Everybody seemed to be terrified. The easiest thing to do was to wear masks on the plane, as my mom suggested. However, it was difficult to wear a mask for 10 hours. The idea was more horrifying than catching the flu! In the end I decided I’d take the masks onto the plane, but not wear them.
Everything seemed okay during the flight. I saw only five people were wearing masks all the time. “Comfort is always the first thing,” I said to myself. When we arrived in Beijing some people came on the plane and took our temperature. Fortunately, nobody had a fever. Therefore, I was able to get home on time.
Unluckily, everything went wrong after I got home. I became sick, with a sore throat and a fever. The horrible image of the flu suddenly hovered in front of me, laughing at me, calling me an ill-behaved child because I had not followed my mom’s words. Luckily, I just had a common cold; probably it was due to the stale air inside the plane cabin. While I was sick in bed, I sighed sadly. If I had listened to my mom in the first place, I probably would have never caught the cold.
It’s always wise to listen to your mom’s suggestions.

B．No, he didn’t. He had a common cold.
C．No. He was healthy.
D．We don’t know.
10．Does the author regret not following his mom’s advice？
A．Yes, he does.
B．No, he doesn’t.
C．No. He followed his mom’s advice.
D．We don’t know.

Several years ago, I spent most of my time at a mental hospital (精神病院) in our town. I found much joy there. At first it was a little scary to be there, but I stayed on, because I had a reason for doing this.
I volunteered in a locked-up (封闭的) environment. To my surprise, I found that a friend of my parents’ was a patient in this hospital. I knew, when I was a baby, this woman wanted to keep me because she had no children. I looked after this woman and showed my old photos to her. Finally, she was able to remember some old things, and she said to me one day, “Dear, you should not come here.” But I wanted to bring something happy into this woman’s life. I learned that because she had no family, she couldn’t leave here and go home. So I brought her to my home twice and I still remembered the happy smile on her face.
I have never forgotten this volunteering experience. This woman later passed away. I can’t see her anymore, but I’m happy that I have done something to make a difference in another person’s life.

Mr. Black’s problems
My name is David Black. I live in a small house. When I eat and drink, I am always worried they are dirty. So when I am hungry or thirsty, I don’t want to eat food or drink water. And I never go out when the weather is cold, because I am worried I’ll have a cold. I don’t go out often because I don’t want to talk with others. I hardly exercise, but sometimes I take a walk in my garden. After I walk for a few minutes, I have to take a rest. I am always very weak and tired. I often have a headache, but I don’t want to see a doctor. What should I do
Dr. Smith’s advice
Traditional Chinese doctors believe we need a balance between yin and yang to be healthy. I think you have too much yin because you are always worried about something and you don’t like going out or talking with others.

And if you don’t feel very well, it’s important for you to go to see a doctor. And you will feel better after you take some Chinese medicine.

Sick while in motion
As the weather gets warmer, there are few things that are better to do than travel. But traveling might not be that fun for everyone, especially for those who have motion sickness.
Motion sickness is also called travel sickness. It is a common experience for many people. Depending on how you travel, it can be called carsickness or seasickness. People with motion sickness feel very uncomfortable while they are in motion. They feel sick and dizzy, like the room around them won’t stop spinning.
It is generally believed that motion sickness happens when your senses become confused with each other, Scientific American reported.
We use different parts of our body to sense movement. Our eyes tell us if we are moving. The inner ears contain a special liquid that helps us sense our direction and balance. Our muscles react to movement.
When you move around, these body parts work well together. But when you are in a car or an airplane, they get confused. Your inner ear signals that you’re moving, but your eyes say you’re sitting still because you can’t see that you’re moving. This mismatch gives us motion sickness.
But some people are less sensitive to motion sickness. This may be because they have certain genes that prevent mismatching senses, Bethann Hromatka, a genetics expert from the US, told the Atlantic.
Although there are many ways to deal with motion sickness, scientists believe that the key is to simply try to adapt to it. For example, some astronauts do special exercises that give them mild motion sickness. After a week or two, the astronauts become used to it and don’t feel uncomfortable anymore, Sam Puma, a NASA flight doctor, told the BBC．
26．People with motion sickness feel very uncomfortable while they are ________.
A．sleeping B．driving C．in motion D．in bed
27．According to paragraph 3, if your senses become confused with each other, ________.
A．you may have cold B．you may have motion sickness
C．you cannot drive D．you should sleep
28．The special liquid in the inner ears can sense________.
A．movement and sickness B．direction and balance
C．movement and balance D．direction and movement
29．Bethann Hromatka thinks that________may prevent mismatching senses.
A．certain genes B．the speed of car C．motion D．travelling
30．What’s the purpose of the passage
A．To introduce motion sickness. B．To introduce sickness.
C．To introduce gene. D．To introduce the parts of body.

American country music is also known as (被视为) country Western music. It has a very long history. It comes from the folk songs of immigrants(移民) from Britain.
Country music uses simple music and words to express everyday feelings such as loneliness, love, and sadness. That is to say, country music describes life. It talks about friends and enemies, trucks and roads, farms and crops…People in many parts of the world like country music, because everyone can understand what the music is about.

When cowboys visited their friends and families on holidays like Thanksgiving, they usually sang and played country Western music.

It was the Olympic Games in Barcelona in 1992; the semi-final of the 400 metres. The sun was shining and the crowd were ready for a great race. British athlete Derek Redmond was a top runner: he had a very good chance of winning a medal.
The race began. At first, Derek was running well. Then, after about 150 metres, he felt a pain in his leg. He fell down on one knee. He had a bad injury and couldn’t carry on. The other runners went past him and finished the race.
After about five seconds, Derek got up and started to run again, on one leg only. Some organizers tried to stop him but he kept going. The crowd stood up and started to clap. Then another man came onto the track—Derek’s father, Jim. His father put his arm around him and said, “Derek, you don’t have to do this.” Derek replied, “Yes, I do. I have to finish.” And so together they walked the last 50 metres and crossed the line.
When he finally crossed the line, Derek was crying and 60,000 people were cheering him. Gerlinde Kaltenbrunner
In the summer of 2010, mountaineer Gerlinde Kaltenbrunner was almost at the top of a mountain called K2. She was trying to climb the 8,611-metre mountain for the fifth time, and this time she was climbing with her friend Fredrik Ericsson.
It was about 7 o’clock in the morning and it was snowing a little. The two climbers were getting ready to go up the last 400 metres. Fredrik was trying to tie some rope but he slipped and fell past Gerlinde. He fell 1,000 metres and was killed.

But there was something very important that she wanted to do: K2 is one of 14 mountains in the world that are 8,000 metres or higher, and her dream was to climb them all.

Focus on mental health
At some point in life, many people suffer a mental disturbance. While most people get over it, for others it doesn’t go away easily.
Oct 10 was World Mental Health Day. This year, the theme was “Young People and Mental Health in a Changing World”.
The World Health Organization says that about 20 percent of children and teenagers worldwide suffer from mental illness. It’s thought that the number of children and teenagers with mental illness around the world will increase by half by 2020. It will become one of the main causes of diseases, disabilities and even death.
In China, the picture isn’t bright, either. About 30 million Chinese children and teenagers under the age of 17, or 10 percent of children and teenagers in China, have a mental health challenge, reported China Daily.
The reason for mental problems among young people may be the increasing pressure in life.
The world is changing fast. Study and relationships have always caused stress, but today the stress is much higher than before, the WHO said.
The Young Foundation, a UK-based non-profit think tank, says that young people today have huge stresses at school. For instance, they experience bullying and body image issues. In a 2017 report, the foundation noted that the internet was a special source of stress. Online, young people often see “messages about perfection” and this causes the young “great uncertainty about their adult futures”, says the foundation.
Also, according to China Daily, Chinese people don’t seek help with their mental problems. They fear that others will think less of them if they admit that they are in trouble. Elaine Peng, a US mental health educator, makes a similar point. She thinks that many Chinese people are ashamed of their mental problems. Peng told Xinhua that mental illness “is taboo in many Chinese families”.
In the UK, over three-quarters of young people believe their mental health problems have a social stigma. YouGov, a UK-based data company, reported in 2017 that a quarter of young UK people wouldn’t ask for help if they developed a mental problem.
Young people who don’t seek help for their condition may be creating problems for themselves in the future. Jagannath Lamichhane, a mental health expert in Nepal, warned that, “If we hide our mental health, it may remain a problem forever.”
“My message for young people is, if you feel something is wrong within you—seek help,” he told NPR.
46．About________ of children and teenagers suffer from mental illness in the world.
A．10% B．17%
C．20% D．30%
47．The underlined words “the picture isn’t bright” in paragraph 4 means________.
A．the picture is dark B．the future is not clear
C．the situation is optimistic D．the situation is not optimistic
48．________was a special source of stress in the report in 2017.
A．Bullying B．Body image C．Internet D．Social stigma
49．According to Jagannath Lamichhane, ________.
A．people shouldn’t pay attention to mental illness
B．people shouldn’t hide mental illness
C．people should ignore mental health
D．people shouldn’t tell others their mental problems
50．What’s the passage mainly about
A．Children and teenagers who suffer a mental disturbance.
B．Ignore mental problems.
C．How to deal with bullying.
D．How to become health.
