2022年春少年素质教育报八年级下人教版语文一、现代文阅读(36分)(一)论述类文本阅读(本题共3小题,9分)阅读下面的文字,完成1~3题。
诗人应该如何回应时代的呼唤,这是一个常说常新的问题。
社会的进步,技术的发展,让我们进入全新的信息时代。
新的传播手段,让诗歌这种曾是少数精英写作的“文学皇冠”艺术,变成了大众传情达意的工具,繁荣和杂芜共存,多样与无序同在,先锋与通俗携手。
诗歌这门艺术,其边界被各种突破和探索改变,在一些人那里,诗歌成了一种面貌模糊的快餐产品。
更有激进者和无知者进行无底线的尝试,以惊世骇俗的语言涂鸦从事所谓的诗歌写作。
因此,真正热爱诗歌并坚守诗歌精神的诗人们,在今天需要更加努力回应时代的呼唤,写出无愧时代的诗篇,这是诗人的天职与担当。
努力提升诗歌精神的时代高度,是中国诗人特别是百年新诗历史所证明的诗之大道。
百年中国新诗的合法性,就是真实地记录并表达了中华民族奋起反抗、争取自由解放的百年心路历程,成为中国人百年来振兴中华的情感史。
中国新诗在民族危亡和社会变革的每个历史时期,都产生了代表性的诗人和里程碑式的诗篇。
在“五四”时期,胡适、郭沫若、徐志摩、李金发、冰心、冯至等,都是开一代风气的大家。
抗战时期,艾青的《我爱这土地》、光未然的《黄河大合唱》、田汉的《义勇军进行曲》,还有田间、李季等一大批诗人的作品,记录了中华民族危亡时用血肉筑起长城的精神。
新中国成立之初,贺敬之的《放声歌唱》,以及郭小川、邵燕祥、闻捷、公刘等诗人的作品,记录了一个站起来的新中国所激起的浪漫情怀。
直到改革开放,重新歌唱的牛汉、绿原等老诗人,以及舒婷、顾城等青年诗人的作品,呈现改革开放和思想解放的中国重新焕发青春的气象……百年新诗历史中,对于与时代与民族紧密联系的诗人,可以列一个长长的单子,写一部厚厚的专著。
坚守中国新诗与时代同行的初心,不忘中国新诗与中华民族同呼吸、为中华民族伟大复兴鼓与呼的使命,中国诗歌一定能产生更多更好的无愧时代的伟大诗篇。

B White’s classic novel Charlotte’s Web, this is exactly what happens.In the story, Wilbur is an unlucky pig. When he was born, he is so small that the farmer wants to end the pig’s life. Luckily, the farmer’s daughter stops him from killing Wilbur and decides to raise the pig in a barnyard(谷仓的院子).Wilbur grows day by day and makes many friends in the barnyard, the spider, Charlotte is one of them. However, one day a sheep tells Wilbur that he will be served up as dinner. But Charlotte has decided to save her friend from this danger. By making words such as“famous pig” in her web(网), she makes the farmer believe that Wilbur is some kind of amazing animal, too important to kill. After Wilbur is saved, Charlotte is so tired that she finally dies.Actually, the writer makes a spider the hero of the book. Many people are afraid of animals like spiders. But Charlotte does everything in her power to keep Wilbur alive. It shows how a strong friendship can last through the worst possible time.31. What is Charlotte according to the passage?A.

We’d better make friends with unexpected people for they can help us.BSome problems are difficult to solve in our life. However, there are a lot of number expressions (表达用语)that can help. Today, let me show you some examples.Sometimes we can “Kill two birds with one stone”. That is to say, we can complete two goals (目标)with only one effort or action. But we must remember that “two wrongs don’t make a right”. If someone does something bad to you, you should not do the same to him.When I was a young child in school, my favourite subject was Maths. My teacher used to “give me three cheers” when I did well in Maths, praising (赞扬)my hard work and good grades.When I was in high school, some of my friends once had trouble doing their schoolwork. In fact, they did not care if they could finish high school. But it seemed that they really got a surprise when they completed their studies and graduated (毕业)from high school. They were “on cloud nine”.“Nine times out of ten”, students who do well in school often find good jobs. Some people work in an office doing the same things every day at nine-to-five jobs.
