April Fool's day is a day {#blank#}1{#/blank#} people can play jokes on others. No one knows for sure how this holiday began. Some English people hold the {#blank#}2{#/blank#} (believe) that it began on the day during the 1200s. At that time, King John of England was in {#blank#}3{#/blank#} habit of making a road out of nearly every path he walked regularly. The citizens of one farm village were aware of this. To protect their grass and farms from being destroyed, they built a fence that prevented the king from walking through their countryside. The king sent a group of soldiers to inform the villagers to remove the fence. {#blank#}4{#/blank#} hearing that, however, the villagers developed a plan of their own. When the soldiers arrived, the villagers ran around and shouted wildly with things {#blank#}5{#/blank#} (throw) away everywhere, behaving as if they {#blank#}6{#/blank#}(go) mad. The soldiers reported to the king that they were so mad as to be beyond punishment. The villagers saved their farmland {#blank#}7{#/blank#} (success) by tricking the king. Now April's day {#blank#}8{#/blank#} (remain) in fashion, {#blank#}9{#/blank#} the tradition only allows tricks from midnight to noon on April 1st. Those who try to play tricks in the afternoon act as {#blank#}10{#/blank#}(fool) themselves and are usually laughed at.

    When I first began my teaching career 20 years ago, a friend of my father said to me, "We were expecting great things from you. You could {#blank#}1{#/blank#}(be) a political leader or {#blank#}2{#/blank#} police chief, but instead you just became a teacher." I told him if I {#blank#}3{#/blank#} (inspire) one of the children that year to be a leader, and one every year for the rest of my career, I would be very proud of my contribution to our community.

    Education is the key to a {#blank#}4{#/blank#}(safe), healthier and wealthier world. {#blank#}5{#/blank#} you are a teacher, you just have chosen the most {#blank#}6{#/blank#} (reward) profession in the world. I sometimes hear from the students who I taught many years ago. They are now adults leading their communities. I got great{#blank#}7{#/blank#} (satisfy).

    Imagine you plant a small and weak tree in your yard. Then you move away. One day you are back. But it looks different now, strong tall, with many{#blank#}8{#/blank#}(branch) and beautiful leaves. You stand in its broad shade, remembering the little tree {#blank#}9{#/blank#}(plant) years ago. That is teaching.

    {#blank#}10{#/blank#} is Koltotrorl that educators are nation-builders. Our world needs them.

    A hotel chain is employing human bed warmers to help guests get a good night's sleep. {#blank#}1{#/blank#} (dress) in special all-in-one sleeping suits, the walking electric blankets are sent to warm the beds of guests staying at the Holiday Inn {#blank#}2{#/blank#} they get under the covers.

    Dr Chris Idzikowski, {#blank#}3{#/blank#} (direct) of the Edinburgh Sleep Centre, said the idea could help people get off to sleep. He {#blank#}4{#/blank#} (explain) that "There's plenty of scientific evidence to show that sleep starts at the beginning of the night {#blank#}5{#/blank#} body temperature starts to drop. The drop occurs partly because the blood vessels (血管) {#blank#}6{#/blank#} the hands, face and feet open up and release heat." "A warm bed –approximately 20 to 24 degrees Celsuis –is {#blank#}7{#/blank#} good way to start this process while a cold bed isn't. It helps people sleep well especially as it's taking much {#blank#}8{#/blank#} (long) for them to warm up when they come in from the snow."

    Dr Chris Idzikowski and {#blank#}9{#/blank#} (he) colleague Jane Bednall said the idea was like "having a giant hot water bottle in your bed". The five-minute free bed warming sessions will be tried out in London and Manchester {#blank#}10{#/blank#} the end of next month.
