    And why do we have them? Scientists are learning to find the reasons, but they still know very little about why we dream.

    Modern research can tell us some important facts about dreams. For example, we have most of our dreams during REM sleep. At this time，the brain is very active. Another fact is that everyone dreams-even if we cannot remember doing so when we're awaken. What's more, an unusual part of our brain has been found. This part sometimes puts our thoughts and memories together in strange ways when we're asleep.

    Some scientists believe that our dreams are associated with life experiences and things in the dreams have their own meanings. For example, telephones in dreams are thought to be about giving or receiving an important message. A car in dreams often mean feelings about your own life. Broken teeth show fear.

    Scientists think that people in our dreams can tell us something about ourselves. If the person in the dream was shouting out, for example, maybe you are angry. If he or she was scared in the dream, then maybe you're afraid of something in life.

    There is still a lot that we do not understand, but scientists are trying hard because the more we learn about our dreams, the more we learn about ourselves.

    Tears come out of my eyes when I talk to my parents on the phone. {#blank#}1{#/blank#} This is what I want to know most. I have supper at 5 o'clock in the dining room. Now it is the busiest time for my parents. Dad works from seven o'clock in the morning to nine o'clock in the evening, so all the housework is left to my mum. {#blank#}2{#/blank#} Every day she gets up at 4 o'clock in the morning, and then works till dark.

    I promise her to study hard in the university because I am her hope. {#blank#}3{#/blank#} I just want her to promise me that she can take care of herself and my dad because they are just like the blood in my body.

    In my family, everyone is equal. We are very happy to have meals together. Mum says that the happiest time for Dad and her is to see my sister and me come back home. We play cards in the room, watch TV and do anything we like, with Dad and Mum preparing delicious food in the kitchen. {#blank#}4{#/blank#} I forget all the difficulties and unhappiness at that time. The only thing I would like to do is to enjoy the time with my parents.

    {#blank#}5{#/blank#} Love your parents as they love us. Give them a call, telling them you love them and miss them.

On Tuesday, it was cloudy and humid(潮湿的).We visited two museums in Central Park. We saw many old things. On Wednesday and Thursday, it was rainy and windy. We walked in the city. We bought some interesting things and ate some delicious food. On Friday, the weather was cool. We went hiking in the mountains.我们很累但是感到很高兴。I really enjoyed my vacation.

    Mr. Guo is a teacher from Xi'an.  He asked his students to hand in their homework through a QR code(二维码). "We spent an hour or two in class learning how to generate(使产生) the codes, and in the end everything gets easier. "Said Mr. Guo, "When students finish the homework, they keep it on WeChat. Then, each student makes his own QR code and gives it to me. So I can cheek their work anywhere using my computer or telephone. "

    The QR codes can be sent to Mr. Guo by email, QQ and WeChat. When Mr. Guo scans (扫描) his students' QR codes, their homework appears on his phone, lie finds that their homework becomes more creative, with many pictures, music and even videos.

    Mr. Guo's students like the new way and think it is interesting. "We are living in the information age. Many students like to work with computers, which makes learning more fun. "Said Tingling, a student of Mr. Guo's.

    "The paper is not easy to keep, hut the code is easy to keep and share." Mr. Guo said," It is worth trying to use new technology in education. Education itself is a kind of creation. I don't want my students to fall behind the times. "

    However, some parents are worried. They are afraid that their children will spend too much time on computers and less time communicating with teachers. But in fact, it's unnecessary. Students still need to look up information in books and write it down when they do their homework. They only use the codes when they hand in their work, which doesn't take them too much time.  Also for teachers, it allows them to cheek the students' work at any time.  And it's also an easy way to share homework with other students.

    Hi! My name is Dave. I am a middle school student but I think my life is different from most other students. After school, I always hunt wild birds and animals with my father, uncles and brothers. I also help them to plant and harvest (收割) crops. I want to be a carpenter. A carpenter is someone who works with wood and fixes (修理) chairs and other things made of wood. I have made lots of things like tables and other furniture.

    My elder sister does many different kinds of things every day. She makes our candles (蜡烛) by using the oil and fat from sheep and cows. These candles give us light at night.

    I think we live a very happy country life.
