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 I was afraid that I would fall off and hurt {#blank#}4{#/blank#}(me). My uncle held onto the seat andhelped me to get  {#blank#}5{#/blank#}the bike. While I was riding, he wasrunning 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, Iheard my uncle shouting, “You are riding it by yourself now!” I was bothexcited and scared. I was really riding by myself, but  {#blank#}7{#/blank#}if I fell off? Could I use the brakesto stop? As I was wondering about this, my uncle ran after me and got hold ofthe bike. I  {#blank#}8{#/blank#}(slow) down and came to a stop. Myheart was still beating fast when I got off the bike. {#blank#}9{#/blank#} (late) that day, having learnt how to get onthe bike and get off it, I felt like I was walking on air! I am still thankfulto my uncle for teaching me to ride a bike on my {#blank#}10{#/blank#} (nine) birthday.

    Friendship's Day in India falls on {#blank#}1{#/blank#} first Sunday of August every year. It is celebrated with many activities.

    Young people in India spend the day with their {#blank#}2{#/blank#} (close) friends and have fun together. Most youngsters in India plan a movie or lunch with their best friends. A large group of friends may also go on a drive to tourist places or make a plan {#blank#}3{#/blank#} camping. Some friends go to the supermarkets to do some shopping. On Friendship's Day most stores offer discounted prices for {#blank#}4{#/blank#} (customer) and it is the perfect day to buy something for friends.

    Some friends go to parties {#blank#}5{#/blank#} (organize) by many restaurants in order to attract youngsters. Such parties are very enjoyable. You can get food at a discounted price. Some friends just decide to meet up at someone's home and talk about {#blank#}6{#/blank#} happy time in the past. The time good friends spend {#blank#}7{#/blank#} (sit) together and talking over a cup of coffee is precious and {#blank#}8{#/blank#} (forgettable).

    Long-distance friends call up each other on this day {#blank#}9{#/blank#} wish each other with warm feelings. Some of them even plan to meet up on this particular day. Yet some others plan a {#blank#}10{#/blank#} (surprise) visit just to see their friends in pleasant shock!

    Happiness can be described {#blank#}1{#/blank#} a positive mood and a pleasant state of mind. There are many factors {#blank#}2{#/blank#}(contribute) to happiness.

    A person in an apparently ideal situation is not {#blank#}3{#/blank#}(necessary) happy. The ideal situation may have little to do with his actual feelings.

    A good education and income are usually considered necessary for happiness. Though both may contribute, {#blank#}4{#/blank#} are only chief factors if the person is seriously undereducated or actually suffering from lack of physical needs.

    The rich {#blank#}5{#/blank#}(be) not likely to be happier than the middle-income group or even those with very low incomes. People with college educations are somewhat happier than those who did not graduate from high school, and it {#blank#}6{#/blank#}(believe) that this is mainly.{#blank#}7{#/blank#} they have more opportunity to control their {#blank#}8{#/blank#}(life). Yet people with a high income and a college education may be less happy than those with the same income and no college education.

    Poor health does not rule out happiness except for the severely {#blank#}9{#/blank#}(disable) or those in pain. Learning {#blank#}10{#/blank#}(cope)with a health problem can contribute to happiness.

    The 9th day of the 9th lunar month is the traditional Double Ninth Festival. It usually {#blank#}1{#/blank#} (fall) in October. In a mysterious book Yi Jing in ancient time, number {#blank#}2{#/blank#} （think）to be "Yang", {#blank#}3{#/blank#}（mean）positive. Because the 9th day of the 9th lunar month is pronounced as "Jiu Jiu" in Chinese, which means "forever", the Chinese ancestors considered it a lucky day worth celebration. That's why ancient Chinese began to celebrate this festival.

    Since {#blank#}1{#/blank#} first fully artificial plastic was invented in 1907, humans {#blank#}2{#/blank#}(find) innumerable uses for the material. It has found {#blank#}3{#/blank#}(it) way into our tools, our clothes and even our bodies. In a new study in {#blank#}4{#/blank#}(environment) science and technology, researchers estimate the average American eats more than 50,000 pieces of microplastic particles, {#blank#}5{#/blank#}(small) than 5 millimeters in length every year and breathes in another 50,000. Although the health {#blank#}6{#/blank#}(effect) of consuming these tiny bits of plastic are unclear, researchers stress the real volume that people are {#blank#}7{#/blank#}(casual) swallowing is alarming. The largest contributor came {#blank#}8{#/blank#} drinking bottled water, in {#blank#}9{#/blank#} the bottle itself added more than 32 times more plastic to a diet {#blank#}10{#/blank#}(compare) with tap water, The Guardian reports.
