    Hello, I am Bob. Last weekend I was busy.

    On Saturday morning, I did my homework. In the afternoon, I did the housework with my mother. I thought I was helpful at home.

    On Sunday morning, I went to the library. I like reading books. I usually read books in the library on Sunday morning. I love science books. After lunch, I went to the park. I played basketball with my friends, S m and Jack. Sam is good at playing basketball. We often play basketball together. In the evening, we had a big dinner. I was happy. I liked my weekend.

    Water is very important to living things. Without water there could be no life on the earth. All animals and plants need water. Man also needs water. We need water to drink, to cook our food and to clean ourselves.

    Water is needed in offices, factories and schools. Water.is needed everywhere. There is water in seas, rivers and lakes.

    Water is found almost everywhere. Even in the desert of the world, there is some water in air. You can't see or feel it when it is part of air. The water in the seas, rivers and lakes is a liquid(液体). The water in air is a gas, and we call it water vapour (水蒸气).

    Clouds are made of water. They may be made of very small drops of water. They may also be made of snow crystals(结晶体). Snow crystals are very small crystals of ice. Ice is frozen water. It is a solid (固体). There can be snow and ice everywhere in winter.

    Water may be a solid, a liquid or a gas. When it is a solid, it may be as hard as a stone. When it is a liquid, you can drink it. When it is a gas, you can't see or feel it.

Dear Sally,

    How are you?

    I'm in the UK now. It's hot today. I wear my yellow T-shirt and pretty white skirt. I go to the farm with my mother and sister. It's Uncle John's farm. It's big and nice. We can see many vegetables in the garden. We try some red tomatoes. They are so good. Uncle John has a lot of animals on his farm. My sister loves the horse very much. I love the cows because I love to drink milk.

Love

Jenny
