Your body is special – no two people in the world are alike, Although you are different from everyone else, you have exactly the same body parts as the people around you, doing different jobs that keep all of us alive.
    What is inside my head ?
    Your head houses the most valuable part of your body – your brain. As you are reading, your eyes send pictures to your brain which makes meaning from what you see. Your brain helps you to remember and think, and makes sure your body is doing what it should.
    What is my skin(皮肤) for ?
    Your skin covers your body. In most parts of your body, the skin is just as thick as half a centimeter. If you have your skin cut, it will have a quick cure and stop viruses from getting into your body. Your skin also helps you feel the heat and coldness of the environment around you. Hair grows from inside the skin. When you feel hot, extra heat comes out through your skin. As a result, your body temperature drops.
    How do I move ?
    Muscles(肌肉) are found in most parts of your body. They work with your bones to help you move – whenever you cry or smile, eat or speak, walk or dance, etc.
    Why do I breathe ?
    Your body needs to take in oxygen from the air and give out the unwanted carbon dioxide in the body. When you breathe, air comes through your nose and mouth into your lungs(肺) where oxygen flows to different parts of your body.
    What makes me sneeze ?
    When dust or a strong smell gets into your nose, you sneeze. This is the way your body cleans up the dust in your nose. Your lungs push out the air and try to clear your nose.
    What does my heart do ?
    Your heart is a very special muscle. It is slightly bigger than your fist (拳头) and grows bigger as you do. If you place your hand on your heart, you will feel your heart beating which forces blood to move around your body.

I went to the UK last weekend to lean English. So far I have already had a few friends and had some traditional English food here. But after having three days of hamburgers, sandwiches and potatoes, I thought none could be more delicious than Chinese food, especially my favourite — huoguo. You can't imagine how excited I was when I got to know that there was going to be a free meal of hotpot to welcome the new students. On the way to the canteen, I seemed to smell huoguo in the air.

To my surprise, when I went into the room, I didn't see any sign of huoguo. Where was it? With many questions in my mind, I sat down to have the free meal. After talking with an English girl, I got to know that Chinese huoguo is completely different from hotpot. Chinese huoguo is written in two words — hot pot. However, hotpot, one word, is a traditional English dish.

Hotpot is made from mutton and onion. On the top are pieces of potatoes. People put it in the oven all day in a heavy pot at a low heat. It takes very little effort to prepare. You can often see it at parties in the UK because it's easy to prepare for a large number of people and is not expensive.

Hotpot doesn't taste bad. However, I still miss huoguo, hot pot, two words!

This is Bob's shopping receipt(收据).

Mr. Lin has been in Britain for two days on vacation. Here is his room card with some information abouthis hotel. 

In Beijing, along the famous Chang' an Street, a lot of bikers ride very expensive bikes. It is said that bikes are priced at between 1,000 yuan and 100,000 yuan. Bike riding becomes popular among people in some big Chinese cities.

Li Ming, who worked as a sales manager at Specialized before, said that people became interested in having a bike especially in China's big cities. He added that now many people could accept high prices for premium(高端的) bikes.

As the two Olympic Games were held in our country, the government started to pay more attention to sports. People began to realize the importance of having a healthy body. It's said that the popularity of bike riding is related(相关的) to the COVID-19 epidemic, people's higher living standards and people's awareness(意识) of the importance of a healthy lifestyle.

At the same time, more and more bike lanes(自行车道) are built in some big cities. People's need for a lot of bikes is a big chance for bike makers. Some best selling road bike s are always sold out quickly.
