A patent is an official document{#blank#}1{#/blank#}(give)to an inventor by a government. This document {#blank#}2{#/blank#}(general) gives inventors the right to stop anyone else from copying, using or selling the invention without their permission.

    Inventions are the result of hard work. It may only take a moment of inspiration to think of a good idea but it takes a lot of research and experimentation to turn it into a(n){#blank#}3{#/blank#} (use)and working invention. So, inventors deserve a reward for the amount of time they spend {#blank#}4{#/blank#}(develop)their ideas. They also need the {#blank#}5{#/blank#}(secure) of knowing that if they share the invention with {#blank#}6{#/blank#}rest of the world, nobody will steal it, use it or copy it without their permission.

    Patents also benefit the society {#blank#}7{#/blank#}return for patent protection. Inventors agree{#blank#}8{#/blank#}(show)all the technical information about their invention. This information is available to everyone and has enough details {#blank#}9{#/blank#}can be used by people with basic knowledge to produce the invention. In this way, patents help to spread new knowledge, which can in turn help people find {#blank#}10{#/blank#}(solve)to different problems or to make further advances in science and technology.

    The lion is a special animal to Chinese people. A pair of stone lions, a male and a female, are {#blank#}1{#/blank#} (common) seen in front of the gates of traditional buildings.

    The lion {#blank#}2{#/blank#} (regard) as the king in the animal world so it represents power. The stone lions are also used to indicate the ranks of {#blank#}3{#/blank#}(official).

    It is interesting to note that China had no lions originally. The earliest stone lions were sculpted{#blank#}4{#/blank#} the beginning of Eastern Han Dynasty (25-220 AD) with{#blank#}5{#/blank#}introduction of Buddhism into ancient China. In the Buddhist faith, the lion{#blank#}6{#/blank#}can protect the Truth and keep off evils, is considered a holy animal of nobleness and dignity. In Chinese folk tales, the lion has become a symbol of {#blank#}7{#/blank#}(brave), power and good luck.

    It was also popular{#blank#}8{#/blank#}(decorate) bridges with sculpted stone lions for the same reason. The {#blank#}9{#/blank#}(well)known of this is the Lugouqiao (also as Marco Polo Bridge){#blank#}10{#/blank#} (build) from 1189 to 1192. A famous proverb says, “The lions on the Lugouqiao are uncountable.”

    New research has found that eating regular balanced meals is more effective(有效的) in managing a healthy weight {#blank#}1{#/blank#} dieting.

    Carried out by researchers at the University of Helsinki, the study looked at 2,452 women and 2,227 men, who {#blank#}2{#/blank#}(ask) to answer surveys which looked at factors(因素) influencing weight changes at age 24, and ten years later at age 34.

    The researchers found among both men {#blank#}3{#/blank#} women, irregular eating and dieting in order to lose weight were two of the main factors that led to weight increasing. A woman's risk of putting on weight was also increased by giving birth to two or more {#blank#}4{#/blank#}(child), regularly drinking sugary drinks and feeling {#blank#}5{#/blank#}(disappoint) with life. For men, smoking was another important factor for putting on weight.

    {#blank#}6{#/blank#}(usual), people try to prevent overweight by dieting. In the long term, it seems to make people {#blank#}7{#/blank#}(get) fatter, rather than prevent it.

    Besides eating regularly and avoiding diets, physical activity was a main factor in {#blank#}8{#/blank#}(help) to protect women from putting on weight, while for men a higher level of {#blank#}9{#/blank#}(educate) and having a greater weight at the beginning of the study appeared to have a protective effect.

    The researchers suggested that those {#blank#}10{#/blank#} want to keep a healthy weight long-term should now consider eating regular meals.

    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.

When I was young, I often saw my grandmother dancing in the garden.{#blank#}1{#/blank#}she was old, her movements were still very beautiful. I fell in love with dancing at that moment. I started learning hip-hop. At first, I watched and followed the{#blank#}2{#/blank#}(dancer) on TV. Then I joined a dance club and made a career of dancing. From then on, dancing has become the most{#blank#}3{#/blank#}(wonder) thing in my life.
