    One day, Allan and his friend Henry went swimming in a river. It was very hot. How happy they were in the river! After they got out of the water, they played games in the sun for a while.
    On their way back, Henry saw some flowers. He liked flowers very much and ran into the green field to look at them. Now Allan was walking by himself.
    Then he heard Henry calling out, "A snake（蛇）! Help!..."
    "What's wrong with you?" asked Allan.
    "A snake bit（咬）me in the leg. Come here!"
    Allan ran over and saw a small red wound（伤口）on Henry' s leg.
    "The snake was in the grass. I didn't see it."
    "Sit down quickly"! Allan told Henry.
    Allan put his mouth at the little red wound and began to suck（吸）at it. In this way he saved （挽救）Henry's life. "Oh, Allan, it's very kind of you to help me."
    "That's all right. We are friends and we must always help each other."

材料一：如今微博、微信的应用越来越多。有的政府部门在官方微信开设了“随手拍”专栏，公民通过该平台实时上传信息，为政府工作建言献策，对政府部门的工作进行监督，提高了政府的行政效能。但同时，也有公民通过微博微信造谣传谣，做出攻击他人、危害社会、损害国家荣誉和利益的违法行为。国家网信办依法关闭了一些网络大V账号，甚至有人因造谣获刑。

材料二：我国仍有几千万群众尚未脱贫，贫困群众的生活，一直牵挂着***的心，当前我国扶贫开发工作已进入“啃硬骨头，攻坚拔寨”的冲刺期，各级党委和政府必须增强紧迫感和主动性，在扶贫攻坚上进一步理清思路、强化责任、采取力度更大、针对性更强，作用更直接，效果更可持续的措施，特别要在精准扶贫、精准脱贫上下更大功夫，确保2020年全部脱贫目标实现。
