Have you ever {#blank#}1{#/blank#} (stay) up late? If so, you know that not getting enough sleep can make you tired. Not sleeping enough can also make {#blank#}2{#/blank#} hard to think clearly the next day.

    Sleep scientists have long known that getting a good night's sleep is of great {#blank#}3{#/blank#} (important). It helps kids to be able {#blank#}4{#/blank#} (do)their best during the day.

    A recent study shows that sleep {#blank#}5{#/blank#} (help) improve problem-solving skills and {#blank#}6{#/blank#}(create) thinking. For the study, two groups of students answered {#blank#}7{#/blank#} math problems. The group that slept for eight hou rs solved the problem {#blank#}8{#/blank#} (correct) more often than the group that did not get enough sleeping.

    While you sleep {#blank#}9{#/blank#} night, your brain is busy doing its “homework”. It sorts out (整理) the information {#blank#}10{#/blank#} you get in the day. Getting enough sleep each night can improve your thinking ability. That will surely help you do your best at school. Experts say that, in return, can lead to better grades.

    Once upon a time, there was a man from the State of Chu who loved his sword very much. One day, he was sitting in a boat   preparing to cross a river {#blank#}1{#/blank#} he accidentally dropped his sword into the water. {#blank#}2{#/blank#} the ship moving fast on and the water running, the people on board reminded that he should go into the water to find his beloved sword back. The man felt in great {#blank#}3{#/blank#} ( anxious) too. However, he turned a deaf ear to that and instead, he {#blank#}4{#/blank#}  (immediate) took out a knife and made a notch（刻痕） on the side of the boat {#blank#}5{#/blank#} his dear sword fell. The people wondered why he did so. He said proudly the notch could help {#blank#}6{#/blank#} (get) his sword back. Shortly after the {#blank#}7{#/blank#} (arrive) at the shore, he entered the water just beneath the notch he made. Though {#blank#}8{#/blank#} (spend) rather a long time, he returned empty-handed. Without doubt, he was laughed at in public and his story became {#blank#}9{#/blank#} well-known joke in China.

    Today the idiom {#blank#}10{#/blank#} (relate) to the story is used to describe a person who stick to rigid rules without considering a changing environment or describes an action made pointless by changing circumstances.

    My friend had a chance to make a trip to Hong Kong {#blank#}1{#/blank#} August 15, 2011. He had dreamed about {#blank#}2{#/blank#} (visit) it since his boyhood and it {#blank#}3{#/blank#} (be) the first time that he had been there. The following was {#blank#}4{#/blank#} he had seen.

    Arriving there, he was happy {#blank#}5{#/blank#} (see) its beautiful scenery and tall buildings. It is said that Hong Kong has the most skyscrapers in the world. Wherever he went, he saw many smiling {#blank#}6{#/blank#} (face) there. People in Hong Kong were easygoing and{#blank#}7{#/blank#} (friend). To {#blank#}8{#/blank#}（he）surprise, he saw that people there always kept order in public places. {#blank#}9{#/blank#} there were many people waiting in line for the next train at the subway station, they tried to talk in a low voice in order not to disturb(打扰) others. Chinese and English are their official(官方的) languages. English is {#blank#}10{#/blank#} (wide) used in governments, markets, service centers and other fields.

    Curiosity is part of human nature. Children are famous for wanting answers {#blank#}1{#/blank#} tons of questions. People keep reading or watching {#blank#}2{#/blank#} they want to find out what happens. But curiosity also provides many practical benefits.

Learning is easiest if you have a genuine desire for knowledge. Curiosity can create that desire when you have a question.

    Many of history greatest discoveries {#blank#}3{#/blank#}(make)by curious people. People wondered {#blank#}4{#/blank#} processes worked or how certain tasks could be done more effectively. Thanks to their curiosity, people now know far more about the world and have useful technology {#blank#}5{#/blank#}(help)them.

    Even if you don't plan to be an inventor of researcher, curiosity can still help you in the classroom. If you develop the joy of learning, classes will become more fun. And you'll excel because you will be fully engaged in the process of learning. Even if you're no longer a student, curiosity will make you better {#blank#}6{#/blank#}(inform)and thus a more capable worker.

    What do you do if you're not already curious? Fortunately, curiosity is a skill that can be improved. If you act like you're curious, you'll quickly start to actually feel curious. Often, the more you learn about a topic the {#blank#}7{#/blank#}(interesting)it becomes.

    As you learn about a topic, gather information from as many sources as possible. Read a variety of books, watch or listen to lectures and ask questions. Don't always get your information from the same source. Instead, learn to appreciate facts that different people know and the different opinions {#blank#}8{#/blank#} they express.

    Ask a lot of questions, Remember, everyone knows {#blank#}9{#/blank#} that you don't. Find out what that is, and ask about it. This lets you learn something and makes the other person happy by letting them show off their knowledge.

In the classroom or out of it, {#blank#}10{#/blank#}(develop)curiosity is sure to be worthwhile.

    Jane was walking round the department store. She remembered how difficult{#blank#}1{#/blank#} was to choose a Christmas present for her father. She wished that he was easy {#blank#}2{#/blank#}(please). Besides, shopping at this time of the year was not {#blank#}3{#/blank#}pleasant experience: people stepped on your feet or {#blank#}4{#/blank#}(push)you with their elbows, hurrying ahead to get to a bargain.

    Jane paused in front of a counter (柜台) {#blank#}5{#/blank#} some attractive ties were on display. But Jane knew from past experience that the {#blank#}6{#/blank#}(choose)of ties hardly ever pleased her father.

    Jane stopped where a small crowd of men had gathered. She found some good quality {#blank#}7{#/blank#}(pipe) on sale. She did not hesitate for long: although her father smoked a pipe only once {#blank#}8{#/blank#} a while, she knew that this was a present which was bound to please him.

    When Jane got home, her parents were already at table having supper. Her mother was {#blank#}9{#/blank#}(excite). "Your father has decided to stop smoking," Jane {#blank#}10{#/blank#}(inform).

    Who invented the ATM? There have been {#blank#}1{#/blank#} (argue) for years over who should officially go down in history as "the inventor of the ATM". Now the UK government is {#blank#}2{#/blank#} (clear) saying it was James Goodfellow {#blank#}3{#/blank#} invented the ATM.

    Back in the mid-1960s, James Goodfellow was working {#blank#}4{#/blank#} a development engineer for Glasgow firm Kelvin Hughes, and had been charged with inventing a way to enable customers to withdraw (取) cash from banks when Saturday opening ended. "Most people {#blank#}5{#/blank#} (work) during the week couldn't get to the bank. They wanted a solution. The solution {#blank#}6{#/blank#} (be) a machine which would issue cash on demand to a {#blank#}7{#/blank#} (recognize) customer," he said. "I set out to develop a cash-issuing machine, and {#blank#}8{#/blank#} (make) this a reality, I invented the pin (personal identification number) and an associated coded token (代币)."

    The cash machine has become a world-conquering piece of technology. There are now 3 million ATMs worldwide, with {#blank#}9{#/blank#} number forecast to hit 4 million by 2020. The good news for Goodfellow is that people are beginning to know him for his invention. Even {#blank#}10{#/blank#} (good) for him, the Home Office has now officially recognized his other achievement.
