    Traveling can teach us a lot in our life. It gives us valuable lessons that schools may not teach. Experiences, skills or challenges we learn through journeys make us wiser and stronger. So let's see some lessons that traveling can bring to us.

    Throw ourselves into the surroundings （周围的事物).

    The world is a wide classroom of life and traveling teaches us how to throw ourselves in a situation and enjoy the surroundings fully. This lesson is especially good for those searching for freedom ( 自由) in heart.

    Don't allow unpleasant things to influence us.

    A journey is not always full of happy moments. Sometimes it is an unpleasant memory: Being a traveler has its own difficulties such as missing planes, losing money, getting sick, and so on. However, don't let these things make our days unhappy. Everything will be OK, so enjoy the journey no matter what happens.

    Just do it.

    We need to give some things that we may not experience a try. In other words, whether we have done it or not, just do it.

    One day Lila's mum took her to see an eye doctor.{#blank#}3{#/blank#} When Lila put on her glasses, she could not believe all the things were so clear! {#blank#}4{#/blank#} She could ride her bike around the neighborhood.{#blank#}5{#/blank#} And she could see the words on the blackboard at school.

Dear Mr. Zhang,

    Next week, a group of exchange students (交换生) from the USA will come to visit Taizhou.

    I make a plan for them. We will eat breakfast at our school first. Then we can take them to Mei Lanfang's Former House (故居) by bus. It takes only 25minutes. They can learn to sing Beijing opera there. In the afternoon, we will go to Tiandehu Park and take some photos there. In the park we can have a picnic as our lunch. Then we will go to the cinema to watch a new film. After that the girls can go to the shopping malls to buy things they like and we will take the boys to our school playground to play football for one and a half hours.

    In the evening we shall invite(邀请) them for dinner in a restaurant. They can try Chinese food. I' m sure they will have a good time in our city.

Yours love,

Tony

    Good study habits are important for all students. When you have good study habits, you will learn faster and find you have a good memory.

    Do you usually study in the living room？This is not a good place for study because it's really too noisy. You need to study in a quiet place, such as your bedroom. A quiet place will help you learn better.

    Before you begin to study, do not forget to clean your desk. It helps you study well, too. Light is important, too. You will feel tired easily if there is not enough light.

    Of all the good study habits you can develop, asking questions is the key. Just ask. No one knows everything, but we can always learn from each other by asking questions.

    When do you work best？Are you an early bird, a night owl (猫头鹰), or something in between ?Find your most productive work time, and then plan to study at this time.
