There was once a woman who decided to kill all the monsters (怪物) in the world. This __1__ took her on a dangerous journey. She met with many __2__ along the way, each testing her strength and abilities.

She hadn't traveled long __3__ she began chasing the monster of hunger. She __4__ him and declared, “You've been causing hunger; __5__ to die.” The monster said, “I acknowledge I bring __6__,but I also bring benefits as well. There would be no __7__ to find food and survive

without me. So look at the ways I might be __8__;don't destroy me.” The woman saw the __9__ in what the monster said, so the monster wasn't killed.

Then she found the monster of suffering and said, “Nobody __10__ to suffer. You're __11__ and I want to kill you.” But he also __12__ for his life, saying, “I do cause pain and sorrow. Yet because of me people __13__ and develop. Remember as a child when you put your hand too close to a fire and experienced the pain of the __14__?Your suffering was short, but you learned from the __15__. This learning has protected you, and this short suffering may have helped to __16__ your life.” The woman then realized another truth — through pain we learn to __17__ pain and appreciate pleasure. So perhaps even suffering has its place if we learn how to __18__ from it.

So she learned that it isn't what the object is, but how we __19__ it, that makes the difference. Experiences of the past __20__ what we do in the present. We can never tell how the unexpected bad events lead to unexpected beautiful new experiences.

语篇解读:本文为夹叙夹议文。看似坏的东西也可以给我们带来好处,本文说明的就是这个道理。

解析:选C由“each testing her strength and abilities”可知,她在途中遇到了许多“挑战(challenge)”。

3.A.while B.before

解析:选D赶上“the monster of hunger”后,需要“接近(approach)”它,让它“准备(prepare)”受死。

5.A.agree B.decide

C.prepare D.turn

8.https://www.wendangku.net/doc/ad6542706.html,eful B.stressful

C.harmful D.hopeful

解析:选A由“I also bring benefits as well”可知,怪物认为它也有“用处(useful)”。

C.truth D.belief

解析:选C根据语境可判断此处指“the monster of hunger”也有其自己的作用这一“事实(truth)”。

10.A.refuses B.wants

C.asks D.pretends

解析:选B根据语境可判断此处意为:没人“想(want)”受苦。

解析:选C suffering也有用,如果你能从中“受益(benefit)”的话,它们也有其作用。

19.A.see B.do

C.express D.believe

解析:选A怪物看似没有价值,但其实有用,关键是你怎么样“看待(see)”它。

20.A.bring B.suggest

C.damage D.change

Ⅱ.短文改错

All of us know the old saying “Practice make perfect.” It tells us unless we want to realize our aim, we should practice, and one day we will make it. It's easy to understand.

Then I watched others who were good at them and asked them the key to succeed.

I went to the swimming pool every day, learned from them and practiced. A day, when my friend pushed me into the swimming pool, I sudden found that I could swim. How exciting I was! Now I can swim much more better than before.

课时跟踪练(十五) 一、选择题(每小题6分,共60分) 1.(2019·北京西城区模拟)下列有关孟德尔的“假说—演绎法”的叙述中,不正确的是() A.在“一对相对性状的遗传实验”中提出了遗传因子的说法B.“测交实验”是对推理过程及结果进行的检验 C.“生物性状是由遗传因子决定的;体细胞中遗传因子成对存在;配子中遗传因子成单存在;受精时,雌雄配子随机结合”属于演绎的内容 D.“F1能产生数量相等的两种配子”属于推理内容 解析:孟德尔在“一对相对性状的遗传实验”中提出了遗传因子的说法,A正确;为了验证做出的假设是否正确,孟德尔设计并完成了测交实验,即让F1与隐性纯合子杂交,B正确;“生物性状是由遗传因子决定的;体细胞中遗传因子成对存在;配子中遗传因子成单存在;受精时,雌雄配子随机结合”属于假说的内容,C错误;“F1能产生数量相等的两种配子”属于推理内容,D正确。 答案:C 2.(2018·江苏卷)一对相对性状的遗传实验中,会导致子二代不符合3∶1性状分离比的情况是() A.显性基因相对于隐性基因为完全显性 B.子一代产生的雌配子中2种类型配子数目相等,雄配子中也相等

C.子一代产生的雄配子中2种类型配子活力有差异,雌配子无差异 D.统计时子二代3种基因型个体的存活率相等 解析:一对相对性状的遗传实验中,若显性基因相对于隐性基因为完全显性,则子一代为杂合子,子二代性状分离比为3∶1,A正确;若子一代雌雄性都产生比例相等的两种配子,则子二代性状分离比为3∶1,B正确;若子一代产生的雄配子中2种类型配子活力有差异,雌配子无差异,则子二代性状分离比不为3∶1,C错误;若统计时,子二代3种基因型个体的存活率相等,则表现型比例为3∶1,D正确。 答案:C 3.(2019·湖北联考)某同学利用性状分离比的模拟实验装置,进行了如下实验:甲、乙两个容器中各放置两种小球,球上标记的A、a代表基因;实验时每次从甲、乙两个容器中各随机取出一个小球,记录组合情况,如此重复多次并计算各种组合间的比例,下列说法错误的是() A.甲容器中的小球可能代表精子,也可能代表卵细胞 B.本实验模拟了两对等位基因之间的自由组合 C.甲、乙两个容器中不同小球的数量比应为1∶1 D.重复的次数越多,组合间的比例越接近AA∶Aa∶aa=1∶2∶1

台。她还嘱咐我们,不要在人前提起父亲是演员。 读初中时,一个男同学悄悄告诉我:“你爸爸的戏演得真好,可惜是个小角色。如果让他演主角,肯定火!” 父亲在家里的时间很少,尤其是进入影视圈后,或是东奔西跑到一个个剧组去找活干,或是找到了活必须随剧组四处游走。每当他一脸倦色回到家里,首先会拿出各种小礼物,送给妈妈、我和妹妹,然后把一沓钞票交给妈妈。 我把男同学的话告诉他,他听了,微微一笑,说:“在一个戏中,只有小人物,没有小角色,这正如社会的分工不同,却都是平等的。主角造气氛,配角助气氛,谁也离不开谁。” 母亲轻轻“哼”了一声,然后下厨房去为父亲做饭菜。 我看见父亲脸上的肌肉抽搐了一下,很痛苦地低下了头。 我读高中妹妹读初中时,父亲在外出三个月后,回到家里。他这次是在一部叫作“五台山传奇录”的电视连续剧里,演一个貌丑却佛力高深的老方丈的侍者,虽是配角,出场却较多,拿了五万元片酬。他给我和妹妹各买了一台笔记本电脑,给妈妈买了一个钻石戒指。 我发现父亲的手腕上绑着纱布,便问:“爸爸,你受伤了?” 他说:“拍最后一场戏时,和一个匪徒交手,从山岩上跌下来,把手跌断了,我咬着牙坚持把戏拍完,导演直夸我敬业哩。” 母亲说:“你也五十出头了,别去折腾了,多在家休息吧。” 他摇了摇头,说:“不!你工资不高,小轩、小轮正读书,将来还要给她们备一份像样的嫁妆。再说,小病小伤在拍戏中是常发生的,别当一回事。” 我和妹妹不由得泪流满面。 后来,我考上了大学,学校就在岳麓山附近。三九严寒的冬天,
