My sister went to see a doctor last week. She supposed she {#blank#}1{#/blank#}(have) some health problems. Her first problem was that she often had back pain {#blank#}2{#/blank#}she always had to sit for a long time to work in her office. The pain almost drove {#blank#}3{#/blank#}(she) mad because she couldn't pay attention to work. The doctor suggested that she should stand up and watch outside after {#blank#}4{#/blank#}(sit) for two hours. She could also do some sports like climbing stairs. The {#blank#}5{#/blank#} (two) problem was that her eyes often felt tired and uncomfortable. This brought much trouble {#blank#}6{#/blank#}her. The reason was that she often used her mobile phone {#blank#}7{#/blank#}the light off at night. The doctor said it was actually {#blank#}8{#/blank#}(harm) to people's eyes. If she wanted to use her mobile phone at night, she must keep the light {#blank#}9{#/blank#}, or the light of the mobile phone may hurt her eyes. Her last problem was she had a stomachache because she didn't eat anything for supper. She was on a diet. The doctor said the idea was {#blank#}10{#/blank#}(fool). She could have anything for supper but she could have it three hours before she went to bed.
