As is known to all, we live in a world of germs（细菌）. It is impossible to avoid exposure. Genetic makeups may give some people {#blank#}1{#/blank#} advantage over others. However, it does not stop people from becoming sick.

    All of us have been a victim of an {#blank#}2{#/blank#} (ill) at some point in our lives. Moreover, it is likely that we {#blank#}3{#/blank#} (get) sick again in the future. Our best chances of avoiding sickness {#blank#}4{#/blank#} (be) by exercising and employing good {#blank#}5{#/blank#} (habit).

    While good hygiene and exercise serve as obvious advice to most people, eating {#blank#}6{#/blank#} (healthy) is not always obvious. If you cannot define “healthy”, then your immune system will be happy {#blank#}7{#/blank#} (tell) you. The immune system is the foundation of our health. It works for us every day to keep us well. Ask {#blank#}8{#/blank#} (you): “Are you making its job easier {#blank#}9{#/blank#} harder?”

    Like any system, the immune system is not different. It has a tolerance too. If you eat unhealthily, your immune system will make you aware of it.

    Take a step in the right direction {#blank#}10{#/blank#} including some healthy food in your diet.

     Siva, the wise father of Ganesh,once called his two sons and suggested a small contest.

    “I will give this sweet to{#blank#}1{#/blank#}goes around the world faster,” he said, holding out a large,delicious milk sweet. Murugan,Ganesh's brother,glowed with pride knowing the prize would soon be{#blank#}2{#/blank#},for he could fly{#blank#}3{#/blank#}(swift) in his chariot（敞篷双轮马车）,circle the earth,and be back in only hours,while his big,clumsy brother Ganesh would take so much{#blank#}4{#/blank#}(long) to do the same.

Bidding farewell to his parents,Murugan set off happily.Ganesh thought for a moment,then smiled and{#blank#}5{#/blank#} (begin) to move.His large elephant with its heavy trunk did slow him down,{#blank#}6{#/blank#}he did not have far to go.For he simply walked carefully{#blank#}7{#/blank#}both of his parents.In a few minutes he had circled them,{#blank#}8{#/blank#} (stand) respectfully in front of his father once again.

    “Father, please give me the prize,”he said.

    “Why? You did not go around the world.You stayed right here,”replied Siva.

    “But Father,” argued Ganesh, “I have just gone around the world.You see, my parents are indeed the{#blank#}9{#/blank#}world to me.”His parents smiled, well pleased.

    Much later, a tired Murugan returned home.{#blank#}10{#/blank#}, the prize was already eaten up.And now you know who won it and why.

    In Canada and the United States, people enjoy entertaining(请客) at home. They often invite friends over{#blank#}1{#/blank#} a meal, a party, or just for coffee and conversation.

    Here are the {#blank#}2{#/blank#} (kind) of things people say when they invite someone to their home: "Would you like to come over for dinner Saturday night?” "Hey, we{#blank#}3{#/blank#}(have) a party on Friday. Can you come?"

    {#blank#}4{#/blank#}(reply) to an invitation, either say thank you and accept, or say you're sorry and give an excuse: "Thanks, I'd love to. What time would you like me to come?" {#blank#}5{#/blank#}"Oh, sorry. I've tickets for a movie."

    Sometimes, {#blank#}6{#/blank#}, people use expressions that sound like invitations(邀请) but which are not real invitations. For example: "Please come over for a drink sometime." "Why not get together for a party sometime?" "Why don't you come over and see{#blank#}7{#/blank#}(we) sometime soon?"

    They are really just polite ways of {#blank#}8{#/blank#}(end) a conversation. They are not real invitations because they don't mention a specific(确定的) time or date. They just show that the person is trying to be{#blank#}9{#/blank#}(friend). To reply to expressions like these, people just say "Sure, that would be great!" or "OK. Yes, thanks."

    So next time when you hear what sounds like an invitation, listen {#blank#}10{#/blank#}(careful). Is it a real invitation or not?

    I can well remember that I was once asked to give a speech titled “A Real Test in My Life” before the whole class at the age of 9! You can imagine how {#blank#}1{#/blank#} (terrible) shy I was the moment I thought of that—with so many eyes {#blank#}2{#/blank#} (look) at me. I had no{#blank#}3{#/blank#} (choose) but to prepare for it, though. First of all, I was to draft(草拟) the speech, which was just a piece of cake for me, a good writer. But the hardest part {#blank#}4{#/blank#} (lie) in my oral presentation from my memory, for to read from the paper was not allowed. The real moment began {#blank#}5{#/blank#} I stood on the platform with my legs trembling and my mind blank. But my listeners {#blank#}6{#/blank#} (wait) patiently without any signs of rushing me. Gradually I found myself back, {#blank#}7{#/blank#}(give) my speech with difficulty. After what seemed to be a hundred years, I found my audience applauding—I made it! From then on, my fear of talking before a big audience disappeared. Actually, with my {#blank#}8{#/blank#}(confident) building up, I now turn out to be a great speaker. Looking back, I know the greatest difficulty on our way {#blank#}9{#/blank#} success is our fear. Overcome(克服) it , and we will be able to achieve our {#blank#}10{#/blank#}(goal).

    Imagine a road crossing without the three-day traffic signal, cars, trucks, school buses, bicyclists and students walking to school would try to rush through the crossing{#blank#}1{#/blank#} the same time. Their safety would be in danger.

    Thanks to an African American{#blank#}2{#/blank#} (invent) named Garrett Augustus Morgan, we have three-way traffic signals that help make crossings much{#blank#}3{#/blank#} (safe). Mr. Morgan was born in Kentucky in 1877. He only received six years' education. As a teen he left his family's farm in search of better{#blank#}4{#/blank#} (opportunity). Living in Cincinnati, Ohio, he continued his studies in English grammar. Then he moved on to Cleveland{#blank#}5{#/blank#}he worked as a repairman for a clothing factory. He had a keen interest in solving problems {#blank#}6{#/blank#} (meet) in everyday life. Later he patented several inventions. The three-way traffic signal was just one of {#blank#}7{#/blank#}. One day he felt very sad when he saw a traffic accident. To help reduce traffic accidents and save people's lives, he {#blank#}8{#/blank#} (immediate) began to work on the invention. Finally, it was {#blank#}9{#/blank#} great success which saved lives then, and {#blank#}10{#/blank#} (be) still saving lives today.

    Fewer than one in seven people can {#blank#}1{#/blank#} ( correct) identify common washing symbols while a {#blank#}2{#/blank#} (three) of people admit they never check instruction labels (标签). Some seven in ten say they ever had machine-washed clothes that should {#blank#}3{#/blank#} (go) to the dry cleaners because they failed to look at the labels.

    The ignorance about {#blank#}4{#/blank#} clothes should be cleaned can cost families thousands of pounds, according to a sample test of householders by a school uniform supplier.

    Men are the worst offenders with more than three quarters always using the same program on a washing machine regardless of the instructions. Almost half of {#blank#}5{#/blank#} (woman) used just three programs. {#blank#}6{#/blank#} is said that the lack of understanding over symbols is destroying thousands of pounds worth of clothing {#blank#}7{#/blank#} (treat) improperly.

    While almost eight {#blank#}8{#/blank#} ten people believe it is important to check the labels on their clothes, less than half look at them when {#blank#}9{#/blank#} (buy) new clothes. Some nine out of ten said they were unaware that some clothing should never be put in the drier.

    The labels are there to show how clothes should be treated. This {#blank#}10{#/blank#} (help) information can save time and ensure clothes to last longer.
