Stephen Hawking, who is one of the famous physicists, was born in Britain on January 8th, 1942. As a child, he was enthusiastic about {#blank#}1{#/blank#} (design) complicated toys but {#blank#}2{#/blank#} (fortune), in his twenties, he suffered{#blank#}3{#/blank#} a disease that was impossible to be cured,{#blank#}4{#/blank#}was a great challenge for him. However, he was not only positive about the misfortunes, and eventually he {#blank#}5{#/blank#} (defeat) all the obstacles but also he was absorbed {#blank#}6{#/blank#}  his research in the universe. In 1988, his best-seller A Brief History of Time {#blank#}7{#/blank#}  (publish), in which he put forward the idea {#blank#}8{#/blank#} time itself has a beginning, and that it will have {#blank#}9{#/blank#}end. In {#blank#}10{#/blank#} (conclude), he has made outstanding contributions to the fields of cosmology and quantum gravity.

    Zac Sunderland is an American who was born in 1991. On July 16^th, 2009 Zac sailed (航行) back to Marina del Rey, California where he had left over a year before. As soon as he arrived, he {#blank#}1{#/blank#} (become) the youngest person in history to sail alone around the world. In order to get the amazing {#blank#}2{#/blank#} (achieve), Zac solved lots of problems.

    When something broke on his boat, {#blank#}3{#/blank#} (thousand) of miles out to sea, Zac had to repair it all by {#blank#}4{#/blank#} (he). Fresh food doesn't last long, so he got used to {#blank#}5{#/blank#} (eat) freeze-dried meals and canned food. And he felt lonely.

    Zac's experiences at sea were not all difficult or miserable(痛苦的). He got {#blank#}6{#/blank#}chances of seeing a night sky more shining than you have ever seen from land, watching {#blank#}7{#/blank#} (beauty) sunrises and sunsets and meeting different marine(海中的) life.

    Zac sailed alone but not non-stop. He made stops along the way {#blank#}8{#/blank#} (add) some more food and fuel. During those stops, he met people from different cultures. His father met him during many of his stops, took him out {#blank#}9{#/blank#} an excellent meal and helped repair the boat {#blank#}10{#/blank#} (frequent).

    Life has become difficult for many villages, and some are disappearing. There are a number {#blank#}1{#/blank#} reasons for this. Firstly, young people from villages usually want to live somewhere livelier and they often move to the towns and do not return. Secondly, people move to the cities to find work, as there are often very few jobs in the countryside. Sometimes villages remain {#blank#}2{#/blank#} people from the cities have bought a "second home" in the village, {#blank#}3{#/blank#}they come and stay at weekends. The price of houses {#blank#}4{#/blank#}(go) up and people from the area cannot afford {#blank#}5{#/blank#}( buy) a house there. Another problem is that it is becoming more and more difficult for farmers to make money from the farms. So they sell their land and find another job.

    My wife and I {#blank#}1{#/blank#} (pay) a visit to my parents in NewYork. We went to a fast-food restaurant for dinner together. My wife went to the counter {#blank#}2{#/blank#} (order) dishes and I stood with my parents.

    My mum is 90 years old. She can hardly see very well and walks with a stick. I was scanning the restaurant, {#blank#}3{#/blank#} (wait) to sit at the first table that was {#blank#}4{#/blank#} (convenience) than others. A woman who was sitting with her son made eye contact with me and asked me to come to her. With a confused {#blank#}5{#/blank#} (express) on my face, I pointed to {#blank#}6{#/blank#} (I) and said, "Me?" She {#blank#}7{#/blank#} (nod) and said, "Yes, you." I walked to the table and she said, "Bring your family here. I can finish eating at the counter. My son is {#blank#}8{#/blank#} a hurry to leave anyway." My eyes were filled with tears as she wiped down the table and guided my dad to seat.

    I always believe that there are {#blank#}9{#/blank#} (nature)kind people in this world. This woman has set a good example to her son, {#blank#}10{#/blank#} is a really lucky guy.

    We all know how good nature can make us feel. The sound of the ocean, the smell of a forest and the way sunlight dances through {#blank#}1{#/blank#} (leaf) help us to relax and think more clearly. The idea {#blank#}2{#/blank#} humans own a deep biological need to connect with nature has been called "Biophilia", {#blank#}3{#/blank#} (mean) "love of life and the living world". Yet, according to the United Nations Population Division, so far the number of us going to urban areas {#blank#}4{#/blank#} (grow) sharply. By 2050, it is estimated that a shocking sixty-eight percent of the world's inhabitants will live in cities. Cities are wonderful places — full of {#blank#}5{#/blank#} (excite), innovation and energy. {#blank#}6{#/blank#} living in a city can be stressful. And the more we live in them, {#blank#}7{#/blank#} more stress we have, leading to increases in mental illnesses {#blank#}8{#/blank#} depression and loneliness. The good news is that the global science community continues to explain the medical benefits of nature on the brain. Through conducting research and sharing information with different organizations, new ideas are being carried out that encourage us {#blank#}9{#/blank#} (step) out of the fast street and reconnect with nature in a {#blank#}10{#/blank#} (rapid) changing world.

Pandas have become one of the symbols of China. They live only on a few high and damp mountains in Southwest China,{#blank#}1{#/blank#}they feed mainly on bamboo leaves and shoots. Everyone in the world {#blank#}2{#/blank#}(agree) that they are adorably cute. Their black and white colour{#blank#}3{#/blank#}(see) as the physical representation of Yin and Yang and how the balance between the two bring harmony and peace.
