Venus is close to Earth．It is the second planet from the Sun．Earth is the third planet from the Sun．Venus is similar to Earth in size and mass (质量).It is often described as Earth's“sister”.

    Scientists have been learning about Venus for a long time．First they looked at Venus through telescopes(望远镜)．But Venus is covered with thick(厚的)clouds．Scientists could not see Venus well through the clouds．So they made guesses about it．

    For a long time, scientists thought that Venus had water and plants．They thought Venus might have animals，too．But they didn't know for sure．

    Then scientists found a way to learn more about Venus．In the 1960s，they began sending probes (航天探测器) to Venus．The probes flew through the thick clouds．They took pictures of Venus up close．They found out many things ,too．The probes sent the pictures and things they found out back to the scientists．

    The scientists learned a lot from the probes．First they learned that most of their guesses were not right．And they learned that Venus is very hot．

    After that，scientists knew they could not send people to Venus．But they still wanted to know more about it．So they sent new probes．These new probes took great pictures of the planet．The pictures showed that Venus has plains(平原)and mountains! And in some ways，Venus looks like Earth．

    While you are at the bookstore, you may be faced with a difficult decision: e-books or paper books? Each one has its advantages and disadvantages. Making the best decision depends on a number of factor (因素).

    An e-reader can carry a whole library wherever you go, which is great for travelers or those who always want a choice of reading material Although e-readers are convenient, high levels of screen brightness from an electronic device(电子设备) can cause eye problems. A study in the Information Science Research found that young people preferred e-readers, like smart phones or iPads. That's why most teenagers are short-sighted.

    Many book lovers still prefer paper books and value the feeling of them. Paper books are very well designed, they look and smell good, and they carry with them a more human touch. Avid (热衷的)readers prefer reading on paper. Perhaps this is their choice because paper books give them a sense of ownership. It is reported that reading on paper rather than an electronic screen is better for memory and focus. But paper books are heavy and they are not convenient to carry.

    Which is your decision, an e-book or a paper book?

    Jim is a nice boy. He is 1.7 metres tall. He is from England. Now he lives in China with his mom and dad. One day，he feels sick. He has a headache. He doesn't want to eat anything. So his father takes him to ________ a doctor by car. The doctor says Jim has a cold. He asks Jim to take some medicine and have a good rest at home.

    I'm forty now. I left school twenty-two years ago. Here's my list of five things I hope to share with you teenagers at school.

{#blank#}1{#/blank#}

    I always wanted to be the best, and one way of feeling good about myself was to see how much better I was than others. There was only one problem with this. When I saw they were better than me, I felt terrible. Now I compare me with myself. I ask myself if I do things as well as I could.

{#blank#}2{#/blank#}

    How much time do you spend worrying about the future? I used to worry a lot. Now I know most things you fear will usually never happen. They're just monsters in your own mind. Even if they happen, they will often not be as bad as you expected. In six months, you probably won't remember most of the things you worry about now.

{#blank#}3{#/blank#}

    When I was young, I often failed to start things I expected to do because I thought they'd taken too long to finish. I always wanted to write a book, for example. But when I thought it might take me more than a year, I lost my enthusiasm(热情). It seemed such a long time. Now I know a year is nothing, if I'd started that book when I was 16, I might have written 10 more by now. I'm upset with myself for not even trying.

{#blank#}4{#/blank#}

    As a young child you try many new things. If you fail, you try again and again until you learn. But at school you are usually encouraged to do things right. Then you stop trying new things in case you get them wrong. You are losing chances to challenge yourselves. I always remind myself: I had fallen off the bike many times before I learned to ride it.

{#blank#}5{#/blank#}

    I hated losing when I was younger. Of course, it's nice to win sometimes and to be the best at something. But we can't all be winners all the time. Learning to lose is one of life's most important lessons. If you try your hardest, then you should never be angry with yourself.

    It's my schoolbag!

    It's 5: 10 in the afternoon. A policeman(警察)stands near No. 2 Middle School. He talks(谈话)with some students.

    "①这是你的书包吗?" asks he.

    "No, it isn't, "says Eric.

    "It looks like(看起来像)John's, "says Mike.

    "No, it is not his schoolbag, "says Tom." His schoolbag is red, but it's green. "

    Mary comes and says, "②Peter can't find his schoolbag. It's his, I think(认为). "

    "It isn't his, "says Harry." His schoolbag is ③      , but it's small."

    "Where is your schoolbag, Jim?" asks Mike.

    "Oh, dear! It's my schoolbag! Thank you! "
