Layla and her family were driving to the town park. It was a hot day. She wanted to swim in the lake. As they got out of the car, Layla saw {#blank#}1{#/blank#} (she) friends.

    "Let's go into the water!" she called. All the kids jumped in {#blank#}2{#/blank#} (happy).

    Layla always has fun at the park. In spring, Layla's dad often takes her fishing in {#blank#}3{#/blank#}(冠词) lake. They usually go early in the morning. The lake water is still (平静的). It is different {#blank#}4{#/blank#} (介词) the river, which has water that runs by

    In summer, {#blank#}5{#/blank#} (family) have picnics near the lake. The kids play and swim in the lake.

    In the morning of autumn, the lake has fog (雾) over it. Layla's dad once{#blank#}6{#/blank#} (tell) her something about fog: Hot summer days warm the water, and then cool autumn air {#blank#}7{#/blank#} (move) over the lake's warm water. The water vapor(水蒸汽) in the air gets cool. It {#blank#}8{#/blank#} (become) small drops of water (水珠). We can see those drops of water hang in the air as fog.

    Layla loves winter at the park too. The cold {#blank#}9{#/blank#} (temperature) turn the water into ice. Many people go skating on the ice.

    The lake looks different at different times of the year, {#blank#}10{#/blank#} (连词) it is always a good place to have fun!

This spring, our teacher suggested we should do a green project and plant some trees around the school. Everyone thought it was {#blank#}1{#/blank#} great idea, so we started looking online for the best trees to buy. But we soon found that {#blank#}2{#/blank#} (choose) trees was not that easy. Our teacher suggested that we should look for trees that grew {#blank#}3{#/blank#} (natural) in our part of the world. That way, the trees would be more suitable {#blank#}4{#/blank#} the wildlife here. We learnt that trees are the{#blank#}5{#/blank#} (happy) when they have room to grow, with plenty of space for their branches. The trees might get {#blank#}6{#/blank#}(damage) close to the school playgrounds, for example. So we tried to avoid areas where students were very active. Finally, we found a quiet corner close to the school garden – perfect! Later we all {#blank#}7{#/blank#} (take) turns to check the trees regularly and make sure they had no strange spots or marks on the {#blank#}8{#/blank#} (leaf). We all knew that we wouldn't be at the school anymore by the time the trees grew tall, and that was a bit sad. {#blank#}9{#/blank#} we'd planted the trees to benefit not only the environment, but also future students at the school. We knew they'd get as much pleasure from them as we had. And that {#blank#}10{#/blank#} (think) really cheered us up!
