Her doctor said that {#blank#}4{#/blank#} (count) sheep might help her fall asleep. She tried this, but soon got tired of it after it failed to work. She finds the nights without sleep almost {#blank#}5{#/blank#} (bear) . She is always sleepy and lacks energy during the day.

    Mary is not alone. Studies show that more than one in three people worldwide struggle with getting enough sleep. It often takes on different {#blank#}6{#/blank#} (form) : some people can get to sleep, but wake up much too early; some get a full night's sleep, but are {#blank#}7{#/blank#} (disappoint)  to find that they still feel tired when they wake up; others, like Mary, find {#blank#}8{#/blank#} difficult to fall asleep in the first place.

    As the plane circled over the airport, everyone sensed that something was wrong. The plane was moving {#blank#}1{#/blank#} (steady) through the air, and although the passengers {#blank#}2{#/blank#} (fasten) their seat belts, they were suddenly thrown forward. At that moment, the air – hostess presented. She looked very pale, {#blank#}3{#/blank#} was quite calm .Speaking quickly and almost in a whisper, she informed everyone that the pilot had fainted and asked if any of the {#blank#}4{#/blank#} (passenger) knew anything about machines. After a moment's hesitation, {#blank#}5{#/blank#} man got up and followed the hostess into the pilot's cabin. Moving the pilot aside, the man took his seat and listened carefully to the urgent instructions that {#blank#}6{#/blank#} (send) by radio from the airport below.

    I started to work in the operating room after nursing school {#blank#}1{#/blank#} (complete). I was{#blank#}2{#/blank#} excited about my new job that I was willing to take turns between being tired and not being able to sleep properly. Like many jobs, the newness and excitement disappeared and I found {#blank#}3{#/blank#}in drudgery(繁重乏味的工作).

    One night I was feeling very tired, since I hadn't slept well{#blank#}4{#/blank#} night before. I didn't like the doctor{#blank#}5{#/blank#}charge, my feet hurt, it was very late, and I was "doing eyes". Every nurse has a favorite (and least favorite) task. My least favorite was eyes - I thought it was always either boring{#blank#}6{#/blank#}unpleasant.

    My patient was an old man who was there to have his cataract(白内障){#blank#}7{#/blank#}(remove) As the {#blank#}8{#/blank#}(operate) neared a close, I started to take the operating cloth off, and put drops (眼药) in the patient' s eyes. We made eye contact and I stumbled(发愣) slightly when he said, "I can see! You are so beautiful.

    I realized then how{#blank#}9{#/blank#}(true) thankful he was and I helped him see! I realized at the moment that no matter how I was feeling, it was what I was doing{#blank#}10{#/blank#}was important.

    Post-00s (《零零后》) is a documentary(纪录片) about growing up. It shows the real lives of children who {#blank#}1{#/blank#} born between 2000 and 2009.

    They struggle with schoolwork. {#blank#}2{#/blank#} (face) with problems in relationships with others, they don't know what to do if a younger brother or sister is born into the family.

    But this five-episode series, which was aired on CCTV9 from Aug 20, is different {#blank#}3{#/blank#} other TV programs with a similar theme.

    Post-00s {#blank#}4{#/blank#}(film) over a period of 10 years, during {#blank#}5{#/blank#} time the show makers followed the growth of a group of kids from kindergarten to middle school. In other words, everything in the series is real.

    Such stories, which {#blank#}6{#/blank#} (know) as "coming-of-age" stories, have a special {#blank#}7{#/blank#}(attract). They feed our curiosity(好奇心) for seeing someone else's life. We become {#blank#}8{#/blank#}(increase) interested in the characters as if we truly knew them.

    And while we enjoy the real stories, because nothing is set in advance, we also can't help {#blank#}9{#/blank#}(feel) the cruelty(残酷) of reality. After all, there's no script(剧本) and there's no turning back—this is real life.

    As US writer Ernest Hemingway once wrote, "Any man's life, told truly, is a novel." And when it comes to Post-00s, it's also such a good documentary {#blank#}10{#/blank#} is worth watching.
