    There's nothing better than having a sweet sleep after a full day of tiring work. Like people, animals need to rest after working hard, too. Some animals sleep in water while others dig holes under the ground. Some even sleep high in trees or under the leaves. Although they sleep in different ways, all of them find ways to have a good rest. 

    Some animals in the sea sleep in strange ways. For example, fish sleep with their eyes open. They seem to look ahead far into the sea when they take breaks. Sea otters(海獭)sometimes sleep in beds of the plants that grow in the sea. This keeps them from moving away. Parrotfish(鹦嘴鱼)blow something from their mouths when they are ready to sleep. Then a bubble(气泡)will be formed around them. The bubble protects them from danger while they sleep. 

    Some animals sleep under the ground. Chipmunks(花栗鼠)sleep curled up(蜷缩)in a ball. Their beds are made of leaves and grass. In winter, they sleep for two weeks and wake up to eat the food. Then they go back to sleep for another two weeks before waking up again. Some desert frogs(青蛙)dig underground holes during the hot and dry season. A frog may stay in its hole for months. 

    High above the ground, monkeys find places in trees each evening before they sleep. The tall trees help to keep monkeys safe during the night. Some insects(昆虫)even sleep under the leaves that will be their next meal. A bee may climb down into a flower to rest. When it climbs out the next morning, it rests well and is ready for work.

    (1)Who blow bubbles when they sleep ?
    A . Sea otters. B . Parrotfish. C . Desert frogs. D . Monkeys.

    (2)What can we know about the chipmunks from the passage?

    【答案】
    (3)What's the main idea of the last paragraph? 
    A . The animals that sleep above the ground. B . Some insects that sleep under the leaves. C . The reason why bees climb down into flowers. D . The ways that keep animals away from danger.
    【答案】
    (4)Which of the following might be the best structure of the passage? 
    A . B . C . D .

    This month, we went on a five day trip to Xishuangbanna, a beautiful place in the south of Yunnan Province. The weather there is hot and wet. There a {#blank#}1{#/blank#} many kinds of plants and animals. I want to i {#blank#}2{#/blank#} some interesting things we saw to you during our trip.

    In the jungle(丛林), we saw a twining(缠绕的)plant. These P {#blank#}3{#/blank#} grow when seeds-seeds mainly from banyan tees (榕树)are moved by animals or wind to some other trees. These seeds gradually grow, developing their own aerial (空气的) roots. Little by lite, they will get themselves around the host tree and f {#blank#}4{#/blank#} kill it, just like a snake kills its enemy.

    A {#blank#}5{#/blank#} thing we learned is that when a tree gets big and strong, some of its aerial roots will grow into the ground and develop into a new tee, just like the way cell division (细胞分裂) works. The w {#blank#}6{#/blank#} tree will look like a small forest. I think this is quite a {#blank#}7{#/blank#}.

    In the forest, you will sometimes find some red leaves among the green leaves. Why is that?

    One reason is that the sunshine is very strong in Yunnan. The trees n {#blank#}8{#/blank#} use all of their leaves in order to do photosynthesis (光合作用) and grow, so the color of some of the leaves c {#blank#}9{#/blank#}to red.

    We really enjoyed our trip to Yunnan. We learned a lot about n {#blank#}10{#/blank#} and had a rally fun time. I hope we can take more trips like this in the future.

     请阅读下面短文。从每小题所给的A、B、C 三个选项中, 选出一个最佳选项

    We all know that being kind can help people in need, but do you know that kindness can also help yourself? 

    According to National Public Radio, the Big Joy Project began in 2021. It spreads the message that people can find happiness in difficult times and use it to do good. 

    The project was open to anyone. More than 70, 000 people from over 200 countries took part in it. All had to take an online survey answering questions about their feelings. Then, they needed to do a small thing every day, such as visiting an elderly neighbor or buying a cup of coffee for a stranger. Finally, they had to take the other survey to compare their feelings before and after.

    The results were announced on November 11, 2023. "We are really excited. Aner the project, there are big changes, including greater happiness, less stress, better sleep, stronger problem-solving abilities, and greater satisfaction with relationships," said Emiliana Simon-Thomas, the leader of the Big Joy Project. 

    "Think of happiness as a skill that you can get through practice, instead of seeing it as something that happens to you. This may make sense, "added Emiliana. 

    Will the changes brought about by doing good last long or disappear soon? The question is not yet answerable. But one thing is certain—doing one good thing can lead to other good things. That's why small acts of kindness can go a long way.
