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.

    My favorite color is orange. It is a warm and bright color, and it makes me feel happy and safe. When I {#blank#}1{#/blank#} (see) this color, I think of fall. When I go outside, I enjoy{#blank#}2{#/blank#} (walk) through the dark orange leaves and listening to the sound they make under my feet. I also think of the smell of fire. It's great to be at home and sit by the warm fire with{#blank#}3{#/blank#} (I) family. This warm and beautiful color should be everywhere this season!

    One day, Nick invited his friends to supper. He was cooking some delicious food in the kitchen .Suddenly, he {#blank#}1{#/blank#}（find）that he had run out of salt. So Nick called to his son," Go to the Village and buy some salt, but pay a fair price for it: neither too much {#blank#}2{#/blank#} too little."

    His son looked surprised. "I can understand why I shouldn't pay too much, Father, but if I can pay less,{#blank#}3{#/blank#} not save a bit of money?"

    "That would be a very {#blank#}4{#/blank#}（reason）thing to do in a big city, but it could destroy a small village like ours," Nick said.

    Nick's guests,{#blank#}5{#/blank#} had heard their conversation, asked why they should not buy salt more cheaply if they could. Nick replied," The only reason a man would sell salt {#blank#}6{#/blank#} a lower price would be because he was desperate for money. And anyone who took advantage of that situation would be showing a lack of respect {#blank#}7{#/blank#}the sweat and struggle of the man who worked very hard to produce it."

    "But such a small thing couldn't {#blank#}8{#/blank#}（possible）destroy a village."

    "In the beginning, there was only {#blank#}9{#/blank#}very small amount of unfairness in the world, but everyone added a little ,always {#blank#}10{#/blank#}（think）that it was only small and not very important ,and look where we have ended up today."
