专项技能保分练(八)主旨大意题A2019安徽省皖江名校联盟联考On a recent night, while I was busy thinking about important social issues, like what to do over the weekend and who to do it with, I overheard my parents talking about my future. My dad was upset not the usual stuff that he and Mom and, I guess, a lot of parents worry about like which college Im going to, how far away it is from home. Instead, he was upset about the world his generation is turning over to mine, a world he fears has a dark and difficult future if it has a future at all.“There will be a disease that kills millions, a disastrous energy crisis, a horrible worldwide depression and a nuclear explosion set off in anger.”As I lay on the living room couch, listening to their conversation, starting to worry about the future my father was describing, I found myself looking at some old family photos. There was a picture of my grandfather who was a member of the class of 1942, the war class. Next to his picture were photos of my greatgrandparents. Seeing those pictures made me feel a lot better. I believe tomorrow will be better than today that the world my generation grows into is going to get better, not worse. Those pictures helped me understand why.I considered some of the awful things my grandparents and greatgrandparents had seen in their lifetimes: two world wars, killer flu, segregation (隔离), a nuclear bomb. But they saw other things, too, better things: the end of two world wars, passage of the civil rights laws.I believe that my generation will see better things, too that we will witness the time when AIDS is cured and cancer is defeated. I will see things as incredible to me today as the Internet to my father when he was 16.体裁：记叙文题材：个人经历主题：明天会更好【语篇解读】文章通过描述作者的父亲对未来的担心，引发了作者对未来的深思。后来作者从一些旧的家庭照片中得到启发：尽管世界充满了糟糕的事情，但是明天一定会越来越好。1Why was the authors dad upset on a recent night?AHe was upset about which college for the author to go to.BHe was upset that the college is too far from the authors home.CHe was worried about his dark and difficult future coming soon.DWhat upset him is whether there is a future for the authors generation.答案与解析：D考查细节理解。根据文章第一段可知，作者的父亲担心的不是作者要上哪所大学、大学离家有多远，而是作者这一代人正在接替他们成为世界的主力，但世界的未来并不明朗，或许还充满艰难与黑暗，故选D项。2What was the authors first reaction to his fathers worry?AIndifferent.

They just sit there photosynthesizing (光合作用) while animals have all the fun. Right? Not so much. A new study has found that there is a long history of interactions between ants and plants. The ant and plants coevolution (共同进化) started with ants feeding on plants and plants evolving antfriendly features.Plants make a number of different structures that are specific for ants to use. Some plants have evolved features that persuade ants into defending them from attack from other insects and even mammals. These include hollow thorns that ants will live inside, or extra nectar (琼浆) on leaves or stems for ants to eat. Some ants will just cheat and take the nectar and run, but some will stick around and attack anything that tries to hurt the plant. Other plants get ants to help them move their seeds around by providing them with rich food packets attached to the seeds. The ant will pick up the seed and carry it away, eat the food packet, and leave the seed often in a nutrientrich area where itll grow better, and since its farther away from its parent, they wont have to compete for resources.But scientists werent sure how the evolutionary relationship between ants and plants got started. If evolution is an arms race between species developing ways to make use of their neighbors, then scientists wanted to know whether plants or ants fired the first shot. It was a chickenandegg question, whether things started with ants developing behaviors to take advantage of plants, or plants evolving structures to take advantage of ants.The history of ants and p
