Whether enveloped by the thick smog from factories or unseen poisons from vehicle waste gases, many cities around the world are losing the battle against air pollution．

    Somewhere, many people died from breathing in the smoke and harmful gases {#blank#}1{#/blank#} (pour) into the air．In China and India, the damage of this poisonous air is particularly alarming, {#blank#}2{#/blank#}(cause) three million deaths in those two countries．As a result, some out-of-breath citizens are turning to bottled air．

    Many companies are compressing fresh countryside air into bottles and {#blank#}3{#/blank#} (sell) it online．It sounds like a joke but the idea is to raise {#blank#}4{#/blank#}(aware) and it provided people {#blank#}5{#/blank#}fresh air at a price．One such company is Vitality, {#blank#}6{#/blank#} collects air from the Canadian Rockies and compresses it into container．Vitality started the business to sell the canned air as joke gifts at first．{#blank#}7{#/blank#} the products took off in a {#blank#}8{#/blank#} ( surprise) way then．So, the manager came up with the business idea {#blank#}9{#/blank#} they can sell fresh air over the world．The manager of the company  has  made {#blank#}10{#/blank#}clear that China, India and South Korea have become its main markets．

    One day a girl was walking in the woods when she found two weak birds. She took them home and put them in a small cage. The {#blank#}1{#/blank#} (care) birds grew strong. Every morning they greeted her {#blank#}2{#/blank#} a beautiful song. The girl loved {#blank#}3{#/blank#}very much and wanted their singing to last forever.

    One day, the girl left the door to the cage open. Immediately, {#blank#}4{#/blank#} larger of the two birds flew out. The girl was afraid that it would fly away and never come back again. So when it flew close, she grasped(抓住) it wildly. {#blank#}5{#/blank#}(fortunate),  the bird died in her hand. It was her love for the bird that killed it.

    She noticed the other bird jumping the cage. She could feel its great need for    {#blank#}6{#/blank#}(free). She lifted it from the cage and {#blank#}7{#/blank#}(set) it free. The bird was flying happily in the sky, {#blank#}8{#/blank#}made the girl so glad. Just then, the bird sat softly on her shoulder and sang the {#blank#}9{#/blank#}(sweet) song she had ever hear.

     The fastest way to lose love is {#blank#}10{#/blank#}（hold） on it too tight; the best way to keep love is to give it wings（翅膀）！

    I don't think it's my parents' job to check my homework. Since we have already grown up, we cannot act like little{#blank#}1{#/blank#} (baby) and depend on our parents all the time. We must learn to be {#blank#}2{#/blank#}(independence).

    I remember when I was in Grade Three, my parents {#blank#}3{#/blank#} (ask) me to check my homework by myself. I didn't know what to do at first, so I only cried. But after that, I got used to {#blank#}4{#/blank#}(check) my own homework in my studies.

    Checking homework by ourselves is {#blank#}5{#/blank#}good habit. It can help us find mistakes in exams more {#blank#}6{#/blank#} (easy), it can also save the teachers a lot of time {#blank#}7{#/blank#} they check our homework, and it can also let our parents worry {#blank#}8{#/blank#}(little) about our studies.

    Some day in the future, Mum and Dad {#blank#}9{#/blank#} (leave) us. So we should start to learn to do everything by {#blank#}10{#/blank#} (we) and really understand how important independence is.

    Howard Carter is one of the most famous{#blank#}1{#/blank#} (explorer) the world has ever known. He was brave and loved {#blank#}2{#/blank#} (visit) and explore new places. During his life, he {#blank#}3{#/blank#} (discover) many amazing things.

    Howard Carter did not go to school, but learnt to draw from his father, {#blank#}4{#/blank#} was an artist. He was bright and curious {#blank#}5{#/blank#} the world outside his home town. In 1891, at the age of 17, {#blank#}6{#/blank#} set sail for Alexandria, Egypt. By the 1920s, he had become an explorer,{#blank#}7{#/blank#} (search) for the tombs of the Egyptian kings. He found several {#blank#}8{#/blank#} (importance) ones. Inside the tombs, he discovered a great fortune in jewels and gold, along {#blank#}9{#/blank#} the preserved bodies of dead kings. These{#blank#}10{#/blank#} (preserve) bodies are known as mummies.

    Generally speaking, a motto is a short and suggestive {#blank#}1{#/blank#} (express) of a guiding principle, {#blank#}2{#/blank#} can inspire people to work for self-betterment. My motto is "God helps those who help {#blank#}3{#/blank#} (they)". Sometimes I am lazy and don't want to work, {#blank#}4{#/blank#} the moment I think of my motto I will become {#blank#}5{#/blank#} (energy) again and devote myself to {#blank#}6{#/blank#} I am doing. I write my motto where I can see it {#blank#}7{#/blank#} (easy). Every time {#blank#}8{#/blank#} (face) with difficulty, I will {#blank#}9{#/blank#} (inspire) with much confidence by the sight of my motto. My motto also makes me become {#blank#}10{#/blank#} independent person. My friends, what is your motto?
