I was nine years old when I learnt to ride a bike. The bike was a birthday present from my uncle. You can imagine how{#blank#}1{#/blank#} (excite) I was when I saw the bike, and I begged my uncle to teach me how {#blank#}2{#/blank#} (ride) it right away. However, before I got on the bike, I felt {#blank#}3{#/blank#} (extreme)  nervous and l  was  afraid  that l  would  fall  off and hurt {#blank#}4{#/blank#} (me).My uncle held onto the seat and helped me to get {#blank#}5{#/blank#} the bike. While l was riding, he was running along beside me, holding the seat so I would not fall over. I was so{#blank#}6{#/blank#} (grate) to him for his help.

    As I was practicing, I became more and more confident. Then, I heard my uncle shouting, "You are riding it by yourself now!" I was both excited and scared. I was really riding by myself, but{#blank#}7{#/blank#} if I fell off? Could I use the brakes to stop? As I was wondering about this, my uncle ran after me and got hold of the bike. I{#blank#}8{#/blank#} (slow) down and came to a stop. My heart was still beating fast when I got off the bike. {#blank#}9{#/blank#} (late) that day, having learnt how to get on the bike and get off it, I felt like l was walking on air! I am still thankful to my uncle for teaching me to ride a bike on my {#blank#}10{#/blank#} (nine) birthday.

    Domestic robots such as the Roomba have already established themselves in the marketplace. Common household appliances such as toasters and microwaves {#blank#}1{#/blank#}(fit) with microprocessors, effectively making them robots, which are bound to do as ordered. The military has begun automating (自动化) many of its frontline systems. The future is wide open for more exploration of these{#blank#}2{#/blank#}(device).

    Automatic factories were some of the first to implement (实施，运用) robotics on the assembly line, performing tasks too dangerous or delicate for humans{#blank#}3{#/blank#}(accomplish). This has continued with whole factories{#blank#}4{#/blank#}(begin) to be automated. IBM has instituted a “lights off' factory in Texas that is {#blank#}5{#/blank#}(complete) automated. Recently Caterpillar{#blank#}6{#/blank#}(announce) plans to operate robotic heavy machinery by 2021, and has already begun transferring much of their crane operations to remote-controlled robots{#blank#}7{#/blank#}obey the orders from computer directions. The medical industry has taken advantage {#blank#}8{#/blank#}robotic surgery assistants for years, most notably the Da Vinci surgical (外科的) helper. With rising health care costs{#blank#}9{#/blank#} the increasing needs of an aging population, hospitals are planning vast expansion in the areas of {#blank#}10{#/blank#}(talent) robotics.

    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!

    As my father had been offered a job in London, our family moved there. {#blank#}1{#/blank#}(lose) all my old friends, I felt shy and lonely at my new school. Luckily for me, I met Roy {#blank#}2{#/blank#} was a popular boy, helping me to get to know people. Roy and I became good friends and we {#blank#}3{#/blank#} (trust) each other. However, five years later, Roy's father was knocked {#blank#}4{#/blank#} by a car and it was his father's death that changed him {#blank#}5{#/blank#} (complete). He became silent and moody, losing interest in his work. Worse still, 3 months ago, I found Roy {#blank#}6{#/blank#} (go) through the pockets of people's coats. And then, small {#blank#}7{#/blank#} (amount) of money started to disappear from students' lockers. Last week, the 500 pounds {#blank#}8{#/blank#} (raise) for a charity was stolen. I wondered {#blank#}9{#/blank#} the thief was Roy so I decided to ask him about the theft. To my surprise, I found a lot of paper notes in Roy's jacket. Should I keep {#blank#}10{#/blank#}a secret or tell the truth?
