    We are lucky to live in a rich country where we have many things. However, most of us usually1some things.

     Electricity is one thing that we waste most. Lights, TVS, 2and other things are often kept on even when no one is using them. We should turn them off when we do not need them. It takes less than a second to do it. Anyhow, not wasting electricity save money, because we do not have to care forthe electricity we do not use.  The second thing that we often waste is water. Fresh water is precious, 3 it shouldn't be wasted. It is only a simple matter of turning off a tap. I am sure 4  can do this easily if he wants to.  5 big waste is food. My mother 6 cook so much food that much of it was thrown away. I told her we had wasted so much 7. She thought I was right and now cooks mainly  what we can eat.

    It is not 8 to be wasteful. I find there is a simple way of not wasting things. That is to use only what we9. Do not touch what we do not need.  10 this way we can stop being wasteful.

阅读甲乙两段文言文，完成下列各题。
      【甲】臣本布衣，躬耕于南阳，苟全性命于乱世，不求闻达于诸侯。先帝不以臣卑鄙，猥自枉屈，三顾臣于草庐之中，咨臣以当世之事，由是感激，遂许先帝以驱驰。后值倾覆，受任于败军之际，奉命于危难之间，尔来二十有一年矣。
       先帝知臣谨慎，故临崩寄臣以大事也。受命以来，夙夜忧叹，恐托付不效，以伤先帝之明，故五月渡泸，深入不毛。今南方已定，兵甲已足，当奖率三军，北定中原，庶竭驽钝，攘除奸凶，兴复汉室，还于旧都。此臣所以报先帝而忠陛下之职分也。至于斟酌损益，进尽忠言，则攸之、祎、允之任也。
      【乙】亮躬耕陇亩，好为《梁父吟》。身长八尺，每自比于管仲、乐毅，时人莫之许也。惟博陵崔州平、颍川徐庶元直与亮友善，谓为信然。
时先主屯新野。徐庶见先主，先主器之，谓先主曰：“诸葛孔明者，卧龙也，将军岂愿见之乎?”先主曰：“君与俱来。”庶曰：“此人可就见，不可屈致也。将军宜枉驾顾之。
       由是先主遂诣亮，凡三往，乃见。因屏人曰：“汉室倾颓，奸臣窃命，主上蒙尘。孤不度德量力，欲信大义于天下，而智术浅短，遂用猖蹶，至于今日。然志犹未已，君谓计将安出?”
