The weather is closely related(联系) to our life. It is all around us all the time. It is an important part of our lives. We cannot control it, but it often controls how and 1 we live, what we do, what we wear and what we eat. Read this passage and learn2 about the weather.

What is the weather?

The weather is just the state of the atmosphere3any time, such as temperature, wind,4sun,etc.

What makes the weather change?

As we know, not every place on the earth gets the same amount of sunlight. Some places get5unlight, so it's warmer in those places. However, some places get little 6no sunlight in winter. Then those places have colder temperatures. These differences in temperature make the air and water 7 around the earth. The movement helps to take the heat energy from the sun across the earth. So the8 changes.

What's the difference between weather and climate?

Climate is a place's weather over a long time. The weather changes from day to day and 9from hour to hour. It can be sunny in the morning and cold and wet in the afternoon. But the climate changes very 10over lots of years. 

    When US student Olivia Priedeman, 17, woke up one morning, she thought she had had a dream about making plans with a friend.

    But it wasn't a dream. Her phone showed that during the night, Priedeman had read a text message from her friend. She did it while she was fast asleep.

    Reading and sending text messages while asleep called─ "sleep texting"─ is an unusual sleep behaviour, similar to sleep walking. It's also a growing problem among doctors: young people can't live without their cell phones.

    One in three teenagers sends more than 100 text messages a day, according to the Pew Internet & American Life Project. And at least four out of five teenagers said they sleep with their phone on or near their bed.

    Elizabeth Dowdell, a professor at Villanova University in Pennsylvania, has studied sleep texting. She said that having a phone nearby all night is a big part of the problem.

    Andrew Stiehm, a sleep medicine researcher with Allina Health in Minnesota, agrees. It's possible for the part of the brain that controls skills to wake up, while the part of the brain that controls memory and judgment(判断) may be still asleep. That's why some people can perform basic movements-such as walking, talking, texting or even driving while they're sleeping. Some of Dowdell's students said that they're disturbed by their nighttime texting behaviour. But because sleep texting is unconscious, it's a difficult habit to break. Dowdell said she knows of some students who wear socks on their hands to keep themselves from texting.

    Marjorie Hogan, a doctor at Hennepin County Medical Centre in Minneapolis, Minnesota, suggests keeping all electronic products outside the bedroom.

    We see many animals, like rabbits, bees, dogs, birds, sheep…，but do you know 1these animals say things? First，let's see a rabbit. When a rabbit sees 2dangerous(危险的)，it runs away at once. When it runs, its tail moves up and 3.When others see this, they run away,4.

    Many other animals use this kind of language(语言). When a bee has found some food, it goes back to 5home. It cannot tell6bees where the food is by speaking to them，but it does a little dance in the air. This may tell other bees 7the food is.

    Some animals say things by8sounds like a man does. For example，a dog barks when a stranger(陌生人)comes near. Some birds can make several 9sounds, each with its own meaning. In a word, every animal10its own language.

    The weather is not the same in many places. In some places it is always 1^, but in other places it is always wet. If the weather is too dry, the land (土地) is not2 for animals or plants. In wet weather there is too much3 and the water in rivers could 4crops (庄稼) away. So people won't have lots of5 to eat. In some other places the weather is very 6. There is always lots of snow. When it snows, all things look 7 

    In winter, days are short and 8 are long. On cold winter nights, when there are no clouds 9 winds, the moon and the stars are very beautiful. People go out to see them. When they 10to their houses, they are always happy to have hot coffee and nice cakes by the fire (炉火).

    As we know, there are four seasons in a year. When spring 1, it's getting warmer and warmer. Everything comes back to life. Trees turn 2. There are beautiful flowers and grass here and there. Children can 3 kites in the sky. 4 summer, the weather becomes hot. 5 people can take part in more activities outside, such as running in the morning, taking a walk in the evening, going camping, 6 in the river, travelling with family, and so on. 7 comes after summer. It's a harvest season. We can taste 8 of fresh fruits. The weather is neither too hot nor too cold. People feel comfortable. It usually snows in winter in my home town. Snowing 9 me excited. Children are 10 in making snowmen outside. A heavy snow will predict a good year. The four seasons bring us happiness and pleasure. We should love and treasure (珍惜) them.
