    We have always been interested in the Moon. 2,000 years ago, people already knew it moves around the Earth and where it would be in the sky at different times of the year. {#blank#}1{#/blank#}

    When scientists could use telescopes to study the Moon more closely, their ideas began to change. They could see the Moon was made of rocks. {#blank#}2{#/blank#} And they believed the Moon had once been a planet. It was caught in Earth's gravity millions of years ago.

    In 1969, Moon rocks were finally brought to the Earth by astronauts. {#blank#}3{#/blank#} To their surprise, scientists found that the Moon and the Earth are made of the same things except for water. {#blank#}4{#/blank#}

    After years of study, some scientists think that the Moon was once part of the Earth. They believe maybe 4 million years ago, something hit the Earth. {#blank#}5{#/blank#}These rocks slowly joined together and after many years became the Moon.

    In the future, even though our ideas about the Moon may change again, we will still be interested in it.

    Not many kids are willing to help around the house, but if you start early and then make a list of chores that need to be done and by whom, they'll soon come to accept it as a part of life.

    ①随着孩子们长大，他们或许会为在家里做家务索要钱。Should you pay them? It's up to you.

    Sarah doesn't think you should ever pay children for chores with money or rewards (奖赏) ."This will make them think that the chore is an 'extra (额外的事物)'that they don't have to do if they don't feel like doing it," says Sarah.

    "If children are trying to save for something specific like a computer game, it may be an idea to give them extra chores like washing the kitchen floor, watering plants or washing the car that you will pay for," "Liz says." ②Then at the end of the month they get a little extra pocket money. It teaches them about saving up, and working for the things they want."
