1.阅读下面的作品,完成各题。
奔跑的稻田汤成难父亲在他五十岁那年突然对我们说:“我要到外面种稻去。
”很长一段时间,我们都是把父亲关于去外地种地的事当做一个笑话。
直到半个月前父亲背着大半麻袋稻种离开村子,我们才感到惊慌。
父亲沿着一条田埂向前走着,我跟在他后面,或者说,我要送一送他。
田埂更很窄,父亲走得如鱼得水。
而我呢,每走几步就从田埂更上滑下去,一屁股坐在泥土里。
为什么不去大路上坐车呢?我问。
只有去城里才需要坐车,父亲回答我。
父亲的回答让人沮丧,然后我继续问道,那你要去哪里呢?外地,他回答得很干脆。
可是,外地在什么地方呢?唔,父亲丝毫没有放幔脚步,腾出一只手向前指了指,唔,外地就在远处吧。
父亲像在说绕口令。
我停了下来,感觉再也走不动了。
父亲叫我回去,你的腿太不经了。
等着吧,我会给你们写信的,父亲说。
我站在田野里看父亲的背影越来越小,小得仿佛钻进了天地之间的缝隙里似的。
这一年,我还在读小学,我只是觉得父亲走起路来有意思极了,我想起刚刚学会的一个成语,摇头摆尾,并用它造了个句——父亲摇头摆尾地走远了。
村里越来越多的人进城了,他们有的是木匠,有的是瓦匠,还有一些是去城里学手艺的。
父亲终于来信了,他在信封里夹了一小支稻花,真的比我从前见到的壮硕多了。
父亲说他舍不得掐下一整株,毕竟一粒花就是一粒米。
稻花是鹅黄色的,散发着来自远方的气息,我将它们拿给母亲和姐姐们看,稻花转了一圈后又扔给了我,可能认为我可以代表全家激动一下。
然而,令我激动的不止是这些,父亲说等收获后就会回来,想想那场景都叫人兴奋,父亲扛着——哦,不,应该是骑着马,马背上装满鼓鼓的袋子,袋子里当然是父亲种出的新米了。

1、阅读下面的文字,完成下面小题。
风雪日月山李迪李老师,我七年前从西北师大毕业,当时有好多地方能签约工作:云南、贵州、宁夏、青海……我挑了又挑,选了青海。
接受我采访、称我李老师的人,名字有点儿怪,叫赵程皇。
一个胖胖的甘肃姑娘,老家在张掖。
她说自己喝凉水都长肉,说是“胜天半子”拆开重组。
我没听明白,她豪爽一笑,天生胖子啊!我俩谈话的地方叫日月山。
这里是青海通往西藏的门户。
山之青海这边儿,屹立着中石油的汇源加油站,胖姑娘就在这里当上了一名加油员。
李老师,你可不知道,刚进十月,这里就下雪了。
我第一天晚上在站里值班,门外似乎有鬼哭狼嚎,嗷,嗷!我从没有听过这种声音,太恐怖了。
老员工说,山口风大,吹到玻璃上就是这声。
外面来车了,赶紧出去加油。
一推门,风把人往里刮。
眼看着离加油机就几步远,愣是过不去。
噎一口,喘半天。
我们这里是换界区,车进藏,油就贵了,司机们都铆足劲儿在这儿把油加满。
人可老多了。
一摸油枪,寒气直接钉进骨头,上牙打下牙,张开嘴都说不出话。
宿舍里没火,冻得睡不着。
站里的被子又小,盖得了脚,盖不住头;一盖头,脚又露出来。
哪儿都冷,哪儿都不舒服。
这时候,我特别想家,想妈,就给妈打电话,说冷,说被子小。
妈说,那么多人都在站上干着,你赵程皇不比别人差。
你要好好的,坚持就是胜利!话是这样说,妈不知道,坚持下来有多难啊!又是一个风雪天,我身上包得跟粽子一样,哆嗦着两手加油。
我站在最外面的机子旁,油枪插进油箱里,两眼不由得看看远山,看看雪。

1、阅读下面的文字,完成下列小题。
材料一所谓“夜经济”,是指发生在当日18点至次日凌晨6点,以本地市民和外地游客为消费主体,以第三产业如休闲、旅游观光、购物、健身、文化、餐饮等为主要形式的现代消费经济。
城市居民消费习惯调查数据显示,2019年国民3%的消费发生在夜间,大型商场夜间销售额超全天总额的50%,餐饮夜间营业额甚至达到全天总额的3%。
夜间休闲成为压力大的城市人的“充电站”,在某种程度上是城市人可以精力充沛、有创造性地投入第二天工作的关键。
我国的夜间经济经历了由单一化经营到多元化发展的过程。
最初,夜间经济是餐饮、购物等消费活动由白天向夜晚的延伸,通过增加营业时间来实现流量增加,北京的簋街、成都的锦里、宽窄巷子等就是夜间经济在这一阶段的代表。
随后,夜间经济业态逐渐丰富,开始出现以夜晚营业为主的服务行业,比如北京的三里屯、后海等商圈汇聚了大部分的酒吧,成为夜间经济的标签。
随着消费需求的不断升级,夜间旅游、演艺体验等新服务业态开始出现并走向成熟,南京的“夜泊秦淮”、桂林的“夜游两江”等均是依托于政府打造的灯光夜景的夜间游船项目;三亚市政府主持修建的海滨大道更是让市民蜂拥而至,看似并未直接产生消费,但是拉动了游客流量,间接增加了城市收入;夜游博物馆、“动物园奇妙夜”夏令营等项目不仅创造了丰厚的经济效益,同时也产生了良好的社会影响。
(摘编自《“夜经济”崛起的背后,这些问题值得思考》,人民论坛网,2019年10月27日)材料二近年来,伴随消费水平的提高,我国居民夜间消费占比逐年提升,“80后”“90后”成为主要消费群体。

B.Unbelievable. C.Ridiculous. D.Strange.25.What does the underlined word“it”in Paragraph 2 refer to?A.Borrowing money.B.Staying another week.C.Praying for an extra week.D.Having a two-week holiday.26.Which of the following best describes Colin?A.Generous. B.Determined. C.Honest.D.Brave.27.What can we learn from the last paragraph?A.They cancelled their holiday for the next year.B.Colin got extremely disappointed upon leaving.C.Their dream to have a two-week holiday came true.D.The author’s mother called the house owner for a bargaining.CIt may help you to know that there is no such thing as a perfect speech. At some point in every speech, every speaker says something that is not understood exactly as he has planned. Fortunately, such moments are usually not obvious to the listeners, why? Because the listeners do not know what the speaker plans to say, they hear only what the speaker does say. If you lose your place for a moment, wrongly change the order of a couple of sentences, or forget to pause at a certain point, no one will be any the wiser. When such moments occur, don’t worry about th em. Just continue as if nothing happened.Even if you do make an obvious mistake during a speech, that doesn’t really matter. If you have ever listened to Martin Luther King’s famous speech—“I have a dream”, you may notice that he stumbles over his words twice during the speech. Most likely, however, you don’t remember. Why? Because you were fixing your attention on his message rather than on his way of speech-making. People care a lot about making mistakes in a speech because they regard speech-making as a kind of performance rather than as an act of communication. They feel the listeners are like judges in an ice-skating competition. But, in fact, the listeners are not looking for a perfect performance. They are looking for a well-thought-out speech that expresses the speaker’s ideas clearly and directly. Sometimes a mistake or two can actually increase a speaker’s attractiveness by making him more human.As you work on your speech, don’t worry about being perfect. Once you free yourmind of this, you will find it much easier to give your speech freely.28. The underlined part in the first paragraph means that no one will _________.A. be smarter than youB. do better than youC. notice your mistakesD. know what you are talking about29. You don’t remember obvious mistakes in a speech because _________.A. you find the way of speech-making more importantB. you don’t fully understand the speechC. you don’t know what the speaker plans to sayD. you attention is on the content30. It can be inferred from the passage that _________.A. one or two mistakes in a speech may not be badB. giving a speech is like giving a performanceC. the listeners should pay more attention to how a speech is madeD. the more mistake a speaker makes, the more attractive he will be31. What would be the best title for the passage?A. How to Be a Perfect SpeakerB. How to Make a Perfect SpeechC. Don’t Expect Mistakes in a SpeechD. Don’t Expect a Perfect SpeechDFear and its companion pain are two of the most useful things that man and animals possess if they are used. If fire didn’t hurt when it burned, children would play with it until their hands were burned away. Similarly, if pain existed but fear d idn’t, a child could burn itself again and again because fear would not warn it to keep away from the fire that had burnt it before. A really fearless soldier—and some do exist—is not a good soldier because he is soon killed; and a dead soldier is of no use.In many cases, you can take quick and successful action to avoid the danger. For example, you see a car coming straight towards you; fear warns you, you jump out of the way, and all is well.In some cases, however, you decide that there is nothing that you can do to avoid the danger. For example, you cannot prevent an airplane crashing into your house, and you may not want to go and live in a desert where there are no airplanes. In this case, fear has given you its warning, you have examined it and decided on your course of action, so fear of the particular danger is no longer of any use to you. Fear and pain are therefore two guards without which man and animals might soon die out.In our first sentence we suggested that fear ought to be properly used. If, for example, you never go out of your house because of the danger of being knocked down and killed in the street by a car, you are letting fear rule you too much. The important thing is not to let fear rule you, but instead, to use fear as your servant and guide. Fear will warn you of dangers; then you have to decide what action to take and try to overcome it.32. Children would play with fire until their hands are burnt away if _________.A. they were not well educated at schoolB. they were fearful of painC. they had never played with fire beforeD. they had no sense of pain33. People sometimes succeed in timely avoiding danger because _________.A. they have gained experienceB. they jump out of the way in timeC. they are warned of the danger and take quick actionD. they are calm in face of danger34. What is implied but not stated in the passage?A. Fear is always something helpfulB. Too much fear is harmfulC . Fear is something that can be avoidedD. Fear ought to be used as our guide in our life35. The best title for this passage should be __________.A. The Value of FearB. Pain and ActionsC. No Pains, No Gains D .
