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 and helpedme 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.

When young F.W. Woolworth was a store clerk, he tried to convince his boss to have a ten－cent sale to reduce inventory(存货). The boss agreed, and the idea was {#blank#}1{#/blank#} great success. This inspired Woolworth {#blank#}2{#/blank#} (open) his own store and price the items at a nickel and a dime (角). He needed capital for such a venture ，{#blank#}3{#/blank#} he asked his boss to supply the capital for part interest in the store. His boss turned him {#blank#}4{#/blank#} directly."The idea is too risky，" he told Woolworth." {#blank#}5{#/blank#} are not enough items to sell for five and ten cents."

Woolworth went ahead {#blank#}6{#/blank#} his boss' support. But he not only was {#blank#}7{#/blank#} (success) in his first store, but {#blank#}8{#/blank#} (eventual) owned a chain of F.W. Woolworth stores across the nation. Later, his former boss {#blank#}9{#/blank#} (hear) to remark，"As far as I can figure out, every word I used to turn Woolworth down {#blank#}10{#/blank#} (cost) me about a million dollars."

    You might want to think twice before purchasing{#blank#}1{#/blank#}(conventional) grown strawberries or spinach(菠菜). According to a new report from the Environmental Working Group(EWG), these foods are the most likely{#blank#}2{#/blank#}(pollute) with the pesticide.

    Even low levels of pesticide exposure can be harmful to infants, babies and young children,{#blank#}3{#/blank#}parents and caregivers should take measures to lower children's exposures{#blank#}4{#/blank#}pesticides while still{#blank#}5{#/blank#}(feed) them diets rich in healthy fruits and vegetables.

    Just last year, the red berry knocked apples and{#blank#}6{#/blank#}(hold) the title of the most polluted. The pesticide increased in strawberries because of out-of-season demand. The most polluted strawberry had traces of 20{#blank#}7{#/blank#}(vary) pesticides.

    Also moving up on{#blank#}8{#/blank#}list this year is spinach. Spinach jumps from the{#blank#}9{#/blank#}(eight) to the second most polluted product. The study finds spinach samples contain more pesticides by weight than all other produce{#blank#}10{#/blank#}(test). In high doses, it can cause damage to the nervous system.

They haven't decided to settle in. {#blank#}1{#/blank#} is more difficult than they expected. (adjust)

    Once there lived a rich man {#blank#}1{#/blank#}wanted to do something for the people of his town. But first he wanted {#blank#}2{#/blank#} (find) out whether they deserved his help.

    In the centre of the main road into the town, he placed{#blank#}3{#/blank#} very large stone. Then he {#blank#}4{#/blank#}(bury) himself behind a tree and waited. Soon an old man came along with his cow.

    "Who put this stone in the centre of the road?" said the old man, but he did not try to remove the stone. Instead, with some difficulty he passed around the stone {#blank#}5{#/blank#} (slow) and continued on his way. Another man came along and did the same thing ; then another came, and another. All of them complained about the stone but not tried to remove {#blank#}6{#/blank#}. Late in the afternoon a young man came along . He saw the stone, {#blank#}7{#/blank#}(say) to  himself ,"The night will be very dark. Some {#blank#}8{#/blank#}(neighbor) will come along later in the dark and will fall against the stone."

    Then he began to move the stone. He pushed with all his {#blank#}9{#/blank#}(strong) to move it. How great his surprise was at last! He found a bag of money {#blank#}10{#/blank#} the stone.
