A best friend is someone to {#blank#}1{#/blank#} you can tell everything, even your most {#blank#}2{#/blank#} (person) feelings and thoughts. Anne Frank treated her diary {#blank#}3{#/blank#} her best friend. The German Nazis were in search of Anne and her family. The family had to{#blank#}4{#/blank#} away from the chase. They didn't dare to go out even in the evenings. They had to stay indoors day and night. Not {#blank#}5{#/blank#} (be) able to go out for such a long time, Anne missed the beauty of nature so much that she grew {#blank#}6{#/blank#} about everything to do with it. She stayed up {#blank#}7{#/blank#} eleven thirty one evening on {#blank#}8{#/blank#} just to see the moonlight. She said, “This is the first time I {#blank#}9{#/blank#} (see) the moonlight since I came here.”

{#blank#}10{#/blank#} (fortunate), the family were discovered at last and taken away from the hiding place.

    For some time, I had been thinking that I wanted to do something to make strangers smile. I decided that I {#blank#}1{#/blank#} (leave) small notes around shops and other public places with positive sayings or kind words for strangers {#blank#}2{#/blank#} (find).

    A friend on Facebook posted that she had received a lot of beautiful paper from an artist friend and was wondering what to do with it. I told her about my idea, and she {#blank#}3{#/blank#} (immediate) said that this must be what her paper was meant for.

    So two friends on opposite {#blank#}4{#/blank#} (side) of the world started leaving these random notes of kindness. I leave my notes without {#blank#}5{#/blank#} (expect) any particular result. It doesn't matter whether they are read {#blank#}6{#/blank#} thrown away. The main thing is that I did this act.

    I now carry around a notebook in {#blank#}7{#/blank#} I write down lovely and inspiring phrases that I find. And I buy packs of Post­ its to write notes on whenever I see {#blank#}8{#/blank#} opportunity to make a stranger smile. I only leave the notes when I am feeling in a {#blank#}9{#/blank#} (happily) mood, as I don't want to pass any negative energy on to someone else.

    I sign them all {#blank#}10{#/blank#} (say) that this note is left for you by a stranger to make you smile. Then, I add a heart.

    Polar bears are suffering in a {#blank#}1{#/blank#} (warm) world than ever before. Polar bears live in environments too cold for most animals. During much of the year, they live and hunt on the{#blank#}2{#/blank#} (freeze) Arctic sea ice. Nature has prepared them for the cold conditions but nothing has prepared the bears for the danger that {#blank#}3{#/blank#} (threat) the only home they know. The scientists have drawn a {#blank#}4{#/blank#} (conclude) that the polar bears' world is melting. Studies show that the polar ice has reduced{#blank#}5{#/blank#}9.8% every 10 years since 1978. Now about 20,000 to 25,000 polar bears live in the Arctic. Polar bears depend on the sea ice for their {#blank#}6{#/blank#} (survive). "The sea ice is more than just this platform that the bears walk over." As Andrew Derocher, a scientist who studies North American polar bear populations puts {#blank#}7{#/blank#}, "Only if polar ice melts quite slowly {#blank#}8{#/blank#}they survive on the earth." Some melting and refreezing of the polar ice is natural. {#blank#}9{#/blank#} in a warmer world, these cycles speed up, and bears have less time to hunt. Normally, they have three months in the spring when they gain more weight. The extra fat is used later, {#blank#}10{#/blank#} the bears are not actively hunting.

    To my dad George H.W Bush's very last days, his life was instructive. As he{#blank#}1{#/blank#}（age）, he taught us how to grow with dignity, humor and {#blank#}2{#/blank#}（kind）.Day could relate to people from all walks of life. He looked {#blank#}3{#/blank#}the good in each person and he usually found it.

    He strongly believed that it was important{#blank#}4{#/blank#}（give）back to the community and country in which one lived. To us, he was the {#blank#}5{#/blank#}（bright）one among a thousand points of light. He taught us what it means to be a wonderful father, grandfather and great grandfather. He taught us that a day was not meant to {#blank#}6{#/blank#}（waste）.

    In his inaugural （就职） address the 41st President of the United States, he said,“ We cannot hope only to leave our children a bigger car, or a bigger bank account. We must hope to give them {#blank#}7{#/blank#}sense of what it means to be a loyal friend, a loving parent, a citizen {#blank#}8{#/blank#}leaves his home, his neighborhood and town better than he found it.”

    Well, Dad, we're going to remember you, and we're going to miss you. So through our{#blank#}9{#/blank#}（tear）, let us know the blessings of knowing and loving you, a great and noble man, the best father a son or daughter could have. And in our grief, let us smile,{#blank#}10{#/blank#}（know）that Dad is hugging Robin and holding Mom's hand again.

    Our cat was ready to give birth to her kittens. My son was curious and excited to see the birth of these new babies. The event took place yesterday. The cat {#blank#}1{#/blank#}(give) birth to one kitten by the time he arrived home from school. He was so amazed at {#blank#}2{#/blank#} he saw. When the second was on its way, the mother cat began to yell very loudly. I saw tears in my son's eyes because he learned about the pain of giving birth.
