Feet are an important part of you. Without them, you couldn't stand up, walk or run around. Your feet work so hard that sometimes they get sweaty (出汗).

Think of a hot summer day when you have been walking around all afternoon. Your feet have been in those trainers for a long time! The moment you take off your shoes, you feel good and relaxed, but your feet smell bad. You may think it is because of the sweat. But in fact, sweat itself has no smell. It's the bacteria (细菌) on your skin (皮肤) that mix with it and gives off a bad smell.

Bacteria love dark and wet places like the inside of sweaty shoes. The sweatier you get, the more bacteria there will be. When you wear your shoes, bacteria will have a good meal on your feet. They eat dead skin cells from your skin and then leave a kind of waste called organic acids (有机酸). These organic acids smell bad. Things will become better if you wear cotton socks.

It is necessary to share your feelings with others. Sharing your feelings helps you to get closer to people you care about and who care about you.

Sometimes it can be really hard not to tell anyone that you're feeling sad, worried, or upset. Don't keep feelings locked inside. If that, it can even make you feel sick!

But if you talk with someone who cares for you, like your mum or dad, you will not be all alone with your problems or worries. It doesn't mean your problems and worries go off, but at least someone else knows what your trouble is and can help you find ways to deal with it.

If the person doesn't understand what you mean right away, try explaining it in a different way or giving an example. Of course, there are many ways for you to share your feelings. If you think you'll have trouble saying what's on your mind, write it down on a piece of paper.

Some of us teenagers, just like some adults (成年人), are more private than others. That means some people will feel shy about sharing their feelings. A kid doesn't have to share every feeling he or she has, but it is important to share feelings when a kid needs help.

I found it hard to communicate with my mother. Relations between us became difficult. 

One day I ran away from home and stayed outside for a few hours. When I returned home at night, I saw all the pain, anger and disappointment on my mother's face. We knew that we were in great need of talk. We agreed to havebreakfast together the next morning. In the end, we decided to go to a restaurant.

On our way to the restaurant, I noticed my mother had two notebooks in her hands. I asked her what they were used for. She explained to me that sometimes it was easier to write our own feelings than talking about them. We should write down our feelings.

Our first topic was"Why am I so angry?" I wrote a half page, and my mom filled up nearly three pages. I saw the tears run down her face while she was writing. I never realized anyone could hide so much anger. After we finished writing, we exchanged our notebooks. As soon as I started reading my mother's words. I began to cry and so did she. When we finished reading, we discussed our feelings. Finally, it felt like all the anger inside me went away from my body. Our talk helped me realize so many things I had never thought of before, not only about my mother but also about other people.

My mother and I continue using our notebooks as a way of communicating. We know that no matter how we feel about each other, our notebooks are a safe place to express our feelings. We have come to an agreement that we write"I love you" at the end of each other.

I'm Tom. This is my room. It's yellow. You can see a desk, a table and a bookcase. A computer and a photo are on the desk. A tape player is in the bookcase. You can see my model planes. They are on my bed.

This is Linda's room. She's my sister. The pink room is big. You can see her photo in a cabinet(柜子). The clock and two books are in the cabinet, too.

This is my parents' room. It's purple. A big bed and a big bookcase are in the room. Lots of books are in bookcase. My parents love reading.

A tornado (龙卷风) is a kind of strong storm with air which moves in a circle quickly. They can move over 200 miles per hour and cause a lot of damage. As they move across the land, they can easily pick up cars, trucks, and even houses, and then throw them very far. It is important to find a safe place if a tornado gets close. 

A safe place could be a basement or the lowest floor. If you are in a home without a basement, try to find a first-floor bathroom or a small room without windows in the middle of your house. You should curl up (蜷缩) into a ball and cover your head and neck with your hands. 

But there are some people who actually want to get close to tornadoes. They are scientists who want to learn more about tornadoes. One of the best ways to do this is to get as close as possible to the tornado. They use special tools to measure (测量) what is happening in and around a tornado. 

One special tool is called a tornado probe (探测仪) . Inside the tornado probe, there are sensors (传感器) to measure wind speed, temperature, pressure, and direction. Some probes even have cameras, so the scientists can see and understand what it's like to be in a tornado.

To be able to get these measurements, the scientists have to get a tornado probe near or into a tornado. Scientists will try to guess where a tornado will go next. Then they drive to that location and put down the probe. If they do not guess correctly, they pick up their probe and r another place. If they are right, the tornado will go near or even right over the probe. Then they take all of the measurements from the probe and use them to predict where future tornadoes may form and travel. And they can give people some warning to keep away from a dangerous tornado. 

There is a great shop in Linda Tutt High School in the USA. It's not the same(相同的) as other shops. {#blank#}1{#/blank#} That sounds very interesting,right? 

{#blank#}2{#/blank#} It wants to help students to be nice to other people. After they do good things for others,the students can get some points(积分). {#blank#}3{#/blank#}

Also, the students can help in the shop in their free time. {#blank#}4{#/blank#} They can learn some job skills(工作技能)there. 

The shop sells things to the students three days a week, from Monday to Wednesday. Every Tuesday,the shop is open to other people for one hour. {#blank#}5{#/blank#}

Because of the shop,many people in need get help. The students in this school learn a lot,too. What a great shop!
