Marry of us wake up feeling{#blank#}1{#/blank#}(tire) in the morning. Many of us ignore the problem as the day goes on,{#blank#}2{#/blank#} (forget) that it might have a{#blank#}3{#/blank#}(danger) effect. Society even glorifies “burning the candle at both ends” as{#blank#}4{#/blank#}sign of our devotion to work and family.

    Believe it{#blank#}5{#/blank#}not, all this bad sleep has far-reaching consequences. We just do not give ourselves enough chances to sleep. A survey of over 74,000 people found 35 percent reported sleeping less than seven hours daily{#blank#}6{#/blank#}average. Furthermore, the amount of sleep{#blank#}7{#/blank#}(change) greatly over the past 15 years.

    This lack of sleep can lead of many serious{#blank#}8{#/blank#}(problem). One study found that{#blank#}9{#/blank#}(simple) limiting yourself to six hours of sleep a night for two weeks had similar effects to staying up all night the night before,{#blank#}10{#/blank#}could make you perform poorly on a timed attention task.

    Are you a man or a mouse? When {#blank#}1{#/blank#} (ask) this question, people want to know {#blank#}2{#/blank#} you think you are a brave person or a coward. But you will never really know the answer to this question until you {#blank#}3{#/blank#} (test) in real life. Some people think they are brave but when they come face to face with real danger, they act like cowards. {#blank#}4{#/blank#} think of themselves as cowards, but when they meet danger, they act like {#blank#}5{#/blank#} (hero).

    When you are in a very dangerous situation and feel afraid, the body automatically produces a chemical {#blank#}6{#/blank#} (call) adrenalin (肾上腺素) in the blood. With adrenalin in the blood system, you feel {#blank#}7{#/blank#} (strong) than ever before. {#blank#}8{#/blank#}, when you are absolutely {#blank#}9{#/blank#} (terrify), the body can produce too much adrenalin, {#blank#}10{#/blank#} makes you find you can't do anything at all.

    Singles' Day falls on November 11th every year in China, {#blank#}1{#/blank#} is recognized as a day for people who have no girlfriend or boyfriend. Couples and lovers have Valentine's Day in celebration of their love, but how about the singles? There must be a day they can celebrate even {#blank#}2{#/blank#} a partner. That's {#blank#}3{#/blank#} people created Singles' Day.

    {#blank#}4{#/blank#} Singles' Day many singles choose to say goodbye to their single lives, {#blank#}5{#/blank#}(attend) blind date parties, and some people even decide to get {#blank#}6{#/blank#} (marry) with strangers. {#blank#}7{#/blank#} this day has recently become more of a time for shopping, because many shops online will give customers great discount to promote their goods.

    More and more people are willing to shop online to get{#blank#}8{#/blank#} they want, and I am one of them. I just can't help {#blank#}9{#/blank#}(buy) things whether I need them or not. {#blank#}10{#/blank#}(honest) speaking, some of the things that I bought have been put aside forever in my closet.

    Zhang Lanping has been teaching for 33 years now, but {#blank#}1{#/blank#} makes her special is her pair of crutches(拐杖). The courageous teacher from Gansu province {#blank#}2{#/blank#} (suffer) from poliomyelitis, an infectious disease, when she was only one year old.

    Zhang is not able to {#blank#}3{#/blank#} (full) recover and therefore has to use crutches for the rest of her life. This condition, however, has not weakened Zhang's spirit. As a student, Zhang devoted {#blank#}4{#/blank#} (she) to acquiring knowledge, which she believed would make her a {#blank#}5{#/blank#} (success) teacher.

    After graduation, Zhang applied as a college teacher but she was turned down because of her physical {#blank#}6{#/blank#} (disable). Zhang did not give up and {#blank#}7{#/blank#} (accept) as a primary school teacher in her hometown in Gansu province, {#blank#}8{#/blank#} then experienced a shortage of teachers. For able­bodied people, it takes only six minutes {#blank#}9{#/blank#} (reach) school, but Zhang has to spend one hour from home to her work place {#blank#}10{#/blank#}(use) crutches. Zhang's efforts have not been in vain. The academic performance of her students is among the best in the district.

   It was already late when we started for the next town, which, according to the map, was about fifteen miles away on the other side of the hill. There we felt sure that we  {#blank#}1{#/blank#}(find) a bed for the night. Soon darkness fell after we left the village,   {#blank#}2{#/blank#} unluckily we met no one when we drove fast along the narrow(狭窄的)road which  {#blank#}3{#/blank#}(lead)to the hill. As our car climbed {#blank#}4{#/blank#} (high), it became colder and the rain began to fall, making it difficult  {#blank#}5{#/blank#}(see)the road.

   After we had traveled for about twenty miles, there was still no sign(迹象)of the town which was  {#blank#}6{#/blank#}(poor)marked on the map. We were beginning to get anxious when the car suddenly stopped. A quick {#blank#}7{#/blank#}(examine) showed that we had used up(用完)the gas. Although we had little food left, we decided to spend the night in the car.  

   With our meals {#blank#}8{#/blank#}(finish), I tried to go to sleep at once, but John, {#blank#}9{#/blank#} was a poor sleeper, got out of the car after a few minutes and went  {#blank#}10{#/blank#} a walk up the hill. There, he found the lights of the town in a valley below.
