    There was a man who had four sons. He wanted his sons to learn not to judge things too{#blank#}1{#/blank#}(quick). So he sent them each to go and look at a pear tree that was far{#blank#}2{#/blank#}

    The first son went in the winter, the second in the spring, the{#blank#}3{#/blank#}in the summer, and the youngest son went in the autumn. When they had all{#blank#}4{#/blank#}(go) and came back, he called them together to describe what they{#blank#}5{#/blank#}(see)．

The first son said that the tree was ugly. The second son said no—it was covered with green buds and full of promise.

    The third son{#blank#}6{#/blank#}(agree). He said it was full of flowers that looked very beautiful.

    The last son said it was full of fruit.

    The man then explained to his sons that they were all wrong，{#blank#}7{#/blank#}they had each seen just one season in the tree's life.

    He told them that you cannot judge what a tree is, or how a person is，{#blank#}8{#/blank#}only one season. The{#blank#}9{#/blank#}(please), joy and love come from that life can only be measured at the end.

    If you give up when it's winter, you{#blank#}10{#/blank#}(miss)the promise of your spring, the beauty of your summer and the fruit of your fall.

    I love reading. At age 6, I could be found reading Harry Potter, a difficult book for a 6-year-old but I {#blank#}1{#/blank#}(enjoy) it all the same. {#blank#}2{#/blank#} soon became obvious that spelling for me was not difficult and I had a wide vocabulary. This is one way I benefited {#blank#}3{#/blank#} reading at such a young age.

    My advice for you as English learners would be to read the English novels {#blank#}4{#/blank#}you have often read in your native language. Reading novels is a great way of {#blank#}5{#/blank#}(improve) your vocabulary and spelling without realising it as you are absorbed（全神贯注的）in the storyline. You know the sorry well, so its {#blank#}6{#/blank#}(usual) easy to follow it in English even if you do not understand every word.

    This is another essential（基本的）point: it's not necessary {#blank#}7{#/blank#}(understand) every word. If you understand the {#blank#}8{#/blank#}(mean) of the sentence, each word is not necessarily important. Quite often, if a word is used several times in a text, you'll gradually get an idea of {#blank#}9{#/blank#} it means.

    Give it a try. If you like reading yon could open up {#blank#}10{#/blank#} whole new world of literature.
