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.

    The Olympic Games are the {#blank#}1{#/blank#}(big) sports meeting in the world. There are two kinds of Olympic Games. One is the Summer Olympic Games, and the other is the Winter Olympic Games. {#blank#}2{#/blank#}of them are held every four years on a regular {#blank#}3{#/blank#}(base). All countries can take part if their athletes have reached the {#blank#}4{#/blank#}(agree) standard to the games. In the past women were not allowed to take part in the Olympic Games. Nowadays, women have a chance {#blank#}5{#/blank#}(play) an important role in the great games. Because of so many athletes, a special village is needed to build for {#blank#}6{#/blank#} to live in, {#blank#}7{#/blank#}(include) a main reception building, several stadiums for competitions, a large swimming pool, and seats for audience {#blank#}8{#/blank#}watch the games. It is a great honor to host the Olympic Games. In addition, for many countries it's just as much competition to host the Olympic Games {#blank#}9{#/blank#} to win Olympic medals. Nowadays, the olive wreath has been replaced by medals. But it's still about being able to run {#blank#}10{#/blank#}(fast), jump higher and throw farther.

    When Jack was a small boy, he was once asked to give a speech about “A Big Challenge in My Life”．To talk before the whole class, he was {#blank#}1{#/blank#} (terrible) shy the moment he thought of so many eyes {#blank#}2{#/blank#} (stare) at him. He had no other{#blank#}3{#/blank#} (choose), though. First Jack was to draft the speech, which was just a piece of cake for him because he was a good writer. But the hard part {#blank#}4{#/blank#} (lie) in his oral presentation, for it was not allowed to read from the paper. He had to give the speech {#blank#}5{#/blank#} his memory and in front of such a big audience!

    A real trial began when Jack stood on the platform with his legs trembling and his mind blank. He didn't know how much time had passed by. His listeners were still waiting patiently and without any signs of laughing. Gradually he found himself back, {#blank#}6{#/blank#} (give) out his speech without much difficulty. After what seemed to be a hundred years, he found the audience applauding. He made {#blank#}7{#/blank#}！From then on, his fear of talking before the audience disappeared. Actually with his confidence {#blank#}8{#/blank#} (build) up, Jack now turns out to be a great speaker. As we know, the greater difficulty we meet on our way to {#blank#}9{#/blank#} (succeed), the {#blank#}10{#/blank#} likely we will achieve our goals.

    Last Monday, the students at an elementary school welcomed a new student. He was not shy at all and seemed {#blank#}1{#/blank#} (recognize) all kids by their names immediately. You may wonder who can do that. Well, the new student was not a human {#blank#}2{#/blank#}a robot. The 1.2 meter tall student is part of a robot experiment. The experiment is to test {#blank#}3{#/blank#}if robots can naturally deal with a group of people.

    {#blank#}4{#/blank#}(compare) to other students, the robot appeared to be smarter than his “classmates”, because he was programmed with the facial{#blank#}5{#/blank#}(photo) and voiceprints of all kids and teachers there. Also, he {#blank#}6{#/blank#}design) with the contents of all the textbooks. As {#blank#}7{#/blank#}result, he impressed everyone by answering every question {#blank#}8{#/blank#} (correct).

    In fact, this is not the first time the robot {#blank#}9{#/blank#} (be) around humans. In the past years he has done many tasks, one of {#blank#}10{#/blank#} was accompanying patients at hospital.

    Chinese high-speed railways are a very. {#blank#}1{#/blank#} (comfort) way to travel. They are clean, quiet and efficient. China has led other developing countries and even some developed ones in this field since the first high-speed train {#blank#}2{#/blank#} (come) into use in 2008.

    The stations are {#blank#}3{#/blank#} (main) built outside the town center, but local transport has been lengthened {#blank#}4{#/blank#} (connect) the high-speed network. The facilities on the train are new and the staff are well trained. Even the second class {#blank#}5{#/blank#} (chair) provide plenty of space. The passages are so wide {#blank#}6{#/blank#} you can move without disturbing anyone. You can use your mobile phone, access {#blank#}7{#/blank#} Internet or work on your laptop. There is also a restaurant car, though the kinds of food {#blank#}8{#/blank#} (be) limited. The toilets arc large, clean and user-friendly too. The train almost doesn't rock. Even when the train brakes, you can hardly feel it shake.

    What's more, with a faster check-in, the high-speed train are also {#blank#}9{#/blank#} (little) affected by weather than planes. Seldom are {#blank#}10{#/blank#} delayed or cancelled for weather condition. Therefore, they have become the first choice for many passengers.
