Using Garbage as a Fuel

    Garbage can be a good fuel to use. The things in garbage do not look {#blank#}1{#/blank#}coal, petroleum, or natural gas, but they are chemically similar to these fossil fuels. As we use up our fossil fuel supplies, we might be able to use garbage as {#blank#}2{#/blank#}energy source. Burning garbage {#blank#}3{#/blank#}( be) not a new idea. Some cities in Europe and the United States {#blank#}4{#/blank#}(burn) garbage for years. The heat that is produced by burning garbage is used to boil water. The steam that is produced is used to make electricity or to heat nearby {#blank#}5{#/blank#}( build). In Paris, France, some power plants burn almost 2 million metric tons of the city's garbage each year. The amount of energy {#blank#}6{#/blank#}(produce) is about the same as would be produced by burning almost a half million barrels of oil!

    But there are problems in using garbage as a fuel. Garbage that burns {#blank#}7{#/blank#}(easy) , such as food and paper, must be separated from metals, glass, and other materials {#blank#}8{#/blank#}do not. Another problem is that burning garbage can pollute the air. Our fossil fuel supplies are {#blank#}9{#/blank#}(limit) . Burning garbage might be one kind of energy source that we can use to help meet our energy needs. This method could also reduce the amount of garbage {#blank#}10{#/blank#}(pile) up on the earth.

    Kids who use media in unhealthy ways may have problems {#blank#}1{#/blank#}relationships, conduct and other emotional symptoms, lead author of a US new study warned.

    A study of the University of Michigan (UM){#blank#}2{#/blank#} (release) recently on its website found that how children use the devices, rather than how much time they spend on them,{#blank#}3{#/blank#} (be) the strongest predictor of emotional or social problems connected with screen {#blank#}4{#/blank#}(addict ).

    The study revealed that {#blank#}5{#/blank#}matters most is whether screen use causes problems in other areas of life or has become{#blank#}6{#/blank#}all-consuming activity.

    Some of the warning {#blank#}7{#/blank#} (sign) include: if screen time interferes with daily activities, causes conflict for the child or in the family, or is the only activity {#blank#}8{#/blank#}brings the child joy. Though much research{#blank#}9{#/blank#} (exist) on adolescents and screen use, this is considered as the first tool to measure how addicted children are to screen media. It will be a{#blank#}10{#/blank#} (value) tool for parents, clinicians and researchers.

    I don't think it's my parents' job to check my homework. Since we have already grown up, we cannot act like little{#blank#}1{#/blank#} (baby) and depend on our parents all the time. We must learn to be {#blank#}2{#/blank#}(independence).

    I remember when I was in Grade Three, my parents {#blank#}3{#/blank#} (ask) me to check my homework by myself. I didn't know what to do at first, so I only cried. But after that, I got used to {#blank#}4{#/blank#}(check) my own homework in my studies.

    Checking homework by ourselves is {#blank#}5{#/blank#}good habit. It can help us find mistakes in exams more {#blank#}6{#/blank#} (easy), it can also save the teachers a lot of time {#blank#}7{#/blank#} they check our homework, and it can also let our parents worry {#blank#}8{#/blank#}(little) about our studies.

    Some day in the future, Mum and Dad {#blank#}9{#/blank#} (leave) us. So we should start to learn to do everything by {#blank#}10{#/blank#} (we) and really understand how important independence is.

    To my dad George H.W Bush's very last days, his life was instructive. As he{#blank#}1{#/blank#}（age）, he taught us how to grow with dignity, humor and {#blank#}2{#/blank#}（kind）.Day could relate to people from all walks of life. He looked {#blank#}3{#/blank#}the good in each person and he usually found it.

    He strongly believed that it was important{#blank#}4{#/blank#}（give）back to the community and country in which one lived. To us, he was the {#blank#}5{#/blank#}（bright）one among a thousand points of light. He taught us what it means to be a wonderful father, grandfather and great grandfather. He taught us that a day was not meant to {#blank#}6{#/blank#}（waste）.

    In his inaugural （就职） address the 41st President of the United States, he said,“ We cannot hope only to leave our children a bigger car, or a bigger bank account. We must hope to give them {#blank#}7{#/blank#}sense of what it means to be a loyal friend, a loving parent, a citizen {#blank#}8{#/blank#}leaves his home, his neighborhood and town better than he found it.”

    Well, Dad, we're going to remember you, and we're going to miss you. So through our{#blank#}9{#/blank#}（tear）, let us know the blessings of knowing and loving you, a great and noble man, the best father a son or daughter could have. And in our grief, let us smile,{#blank#}10{#/blank#}（know）that Dad is hugging Robin and holding Mom's hand again.
