Ⅰ.阅读理解
(2020河南林州一中高二月考,)
It seems we can't get ff the planet fast enugh. Tw thirds f NASA's mney is spent n manned space explratin, and that number will grw with the USA's decisin t send a man t Mars in 2037. We've seen all there is t see n Earth, right? Wrng. The final place is here—under the surface f the sea.
Heading dwn int the cean, humans' limits are quickly reached. At 200 metres, the water is as black as a mnless night. Mst nuclear submarines(核潜艇)will implde(内爆)befre their depth reaches 1 km. At 3 km — still less than the average depth f the cean—there's a gd chance that yu'll discver a new species. The deepest-diving whales g n further. At the very bttm—abut 11 km dwn—lies the Challenger Deep, the deepest part f the Mariana Trench in the Pacific Ocean. Twelve humans have walked n the Mn, but nly three have seen the Challenger Deep with their wn eyes.
Yet things live dwn there. Big things. A very lud sund was nce heard and scientists believed that it was prduced by an animal bigger than a blue whale, the largest creature knwn n the planet.
In the late 1990s, a deep-water submarine was drpped in the Suthern Ocean, and at 4,000 metres, it discvered smething huge passing under it. Surprised? Dn't be. The cean cvers abut 70% f the planet's surface and we've studied less than 5% f it. We knw mre abut the dark side f the Mn than abut the underwater wrld.
One reasn that we explre space is t find evidence f ther life frms. The search fr life utside f Earth is imprtant, but rbts can lk under the dry rcks f Mars better than humans. They're abslutely imprtant fr ding cean research, t, but they can't lk under the sea. The cst f explratin is rising, but the results wuld benefit ur lives. Understanding the ceans will help us find new surces f fd, drugs and energy.
Perhaps nw it's time t begin a new perid f sea explratin. The manned explratin f space is science fictin. The adventure in the deep sea is the science fact.
1.What des Paragraph 2 suggest?
A.Sea explratin is n easy task.
B.Nuclear submarines need t be imprved.
C.The cean is far deeper than peple have expected.
D.The cnditins under the sea are similar t thse n the Mn.
2.What d we knw abut the Challenger Deep?
A.Blue whales live there.
B.N ne has ever been there.
C.Peple are terrified at the sight f it.
D.It is the deepest knwn lcatin n Earth.
3.What des the authr think f the discvery in the Suthern Ocean?
A.It's surprising.B.It's n wnder.
C.It's wrrying.D.It's n success.
4.What des the authr want t tell us?
A.Space explratin is f little value.
B.We spend t much mney n space travel.
C.Humans' success lies in hw much they explre the sea.
D.The cean is the place where we shuld make ur effrts.
Ⅱ.七选五
(2020吉林吉化第一高级中学校高二期末,)
All living things in the cean are endangered by humans plluting the water. 1 . One way is the dumping(倾倒) f certain waste materials, such as garbage and used water, int the cean. The harmful bacteria that feed n the garbage use up much f the xygen in the surrunding water, s ther creatures in the area ften dn't get enugh.
Other substances(物质), such as radiactive waste materials, can als cause pllutin. 2 . But after years f being expsed t the cean water, the cntainers may begin t leak(漏).
3 . Oil is spilled int the cean when il ships sink r when il wells in the cean cannt be capped. The il cvers the gills(腮) f fish and prevents them frm breathing. Diving birds get the il n their wings and are then unable t fly. When they clean themselves, they are ften pisned by the il.
Rivers can als cntribute t the pllutin f ceans. 4 . Fertilizers used n the farmlands may be carried t the cean, where they cause a great increase in the number f certain plants. T many f sme plants can actually be pisnus t fish.
Wrse are the pesticides(杀虫剂) carried t the cean. These chemicals slwly build up in fish and ther small animals. 5 . The build-up f these chemicals in the animals can make them ill r cause their babies t be brn dead r sick.
A.Fish and turtles suffer the mst
B.Pllutin ccurs in several ways
C.Oil is anther majr surce f cncern
D.Many rivers receive the water frm farmlands
E.Farmers use these artificial fertilizers t increase the crp harvest
F.These substances are ften placed in the water in safely sealed cntainers
G.These animals then pass the pesticides n t the larger animals that feed n them

“That's nthing. I'll treat yu tday,” said the man. “Cme in.” The seller brught her a bwl f ndles, the smell s attractive. As she was eating, Jenny cried silently. “What's up?” asked the man kindly. “Nthing. Actually I was just tuched by yur kindness!” said Jenny as she wiped her tears. “Even a stranger in the street will give me a bwl f ndles, while my mther drve me ut f the huse. She shwed n care fr me. She is s merciless cmpared t a stranger!” Hearing the wrds, the seller smiled, “Girl, d yu really think s? I nly gave yu a bwl f ndles and yu thanked me a lt. But it is yur mther wh has raised yu since yu were a baby. Can yu number the times she cked fr yu? Have yu expressed yur gratitude t her?” Jenny sat there, speechless and numb with shck;she remembered her mther's familiar face and weathered hands. “Why didn't I think f that? A bwl f ndles frm a stranger made me feel indebted(感激的). Why haven't I thanked my mum fr what she has dne fr me?” On the way hme, Jenny made up her mind t make an aplgy t her mther fr her rudeness as sn as she arrived hme.

Ⅱ mercy 2.amunts f 3.be respnsible fr

Ⅲ 考查名词。句意:智利的自然环境保护主义者对森林商业化开发的影响感到担忧。根据空前的形容词cmmercial与空后的f可知,此处应填名词explitatin。
2.merciful 考查形容词。句意:他们要她对犯人慈悲一些。be后应跟形容词,故填merciful。
3.pssessins 考查名词。句意:地震把整个村庄夷为了平地,人们失去了他们的家园和所有的财产。根据空前形容词性物主代词their可知此处应填入名词,因pssessin的复数表示“财产”,故填pssessins。
4.causing 考查非谓语动词。句意:一场地震袭击了青海省玉树,造成了建筑物的损坏和人们的惊慌。此处考查非谓语动词作结果状语,句子主语An earthquake与cause是主动关系,故填现在分词causing。

Ⅰ.◎语篇解读 本文是一篇说明文。作者认为比起对太空的探索,人类对深海的探索或许更具现实意义。
1.A 细节理解题。第二段提到,已有12个人在月球上行走过,但是目睹挑战者深渊的却只有3个人。由此可见比起探索太空,人类对于深海的探索更艰难,探索大海绝非易事,故选A项。
2.D 细节理解题。由第二段At the very bttm—abut 11 km dwn—lies the Challenger Deep, the deepest part f the Mariana Trench in the Pacific Ocean.可知,挑战者深渊位于大概11千米深的海底,是马里亚纳海沟最深的部分。与 D项相符,故选D项。根据nly three have seen the Challenger Deep with their wn eyes可排除B项;第三段提到an animal bigger than a blue whale,由此可知住在那里的不是蓝鲸,而是比蓝鲸大的一种动物,故排除A项;文章并未谈到人类害怕看见它,故排除C项。
3.B 推理判断题。由第四段的Surprised? Dn't be. The cean cvers abut 70% f the planet's surface and we've studied less than 5% f it. We knw mre abut the dark side f the Mn than abut the underwater wrld.可知,对于在南冰洋的发现,作者并不感到惊讶,地球表面约有70%被海洋覆盖,人类对海洋的研究还不到5%。我们对月球阴暗面的了解都比海底世界多。故选B项。
4.D 推理判断题。由倒数第二段内容可知,对于太空的探索很重要,可机器人会比人类做得更好。但机器人不能在海底探索。虽然勘探海洋费用增加了,但可能帮人类找到更多食物、药品和能量来源,故人类应该在海洋探索方面努力。故选D项。
【高频词汇】 1.species n.物种 2.bttm n.底部,水底 3.creature n.动物,生物 4.evidence n.证据 5.surce n.来源
Ⅱ.◎语篇解读 本文是一篇说明文。海洋面临着人类倾倒的废物、放射性物质、泄漏的石油和河流的污染,海洋中所有生物的生存都因海水被污染而受到了威胁。
1.B 根据前句All living things in the cean are endangered by humans plluting the water.和后句One way is the dumping(倾倒) f certain waste materials, such as garbage and used water, int the cean.可知,B项“污染以一些方式发生”承上启下,符合语境。故选B。
2.F 根据后句But after years f being expsed t the cean water, the cntainers may begin t leak(漏).可知,F项“这些物质经常被放到水中安全密封的容器里”符合语境。故选F。
3.C 下文多次出现了il,由此可知此处指的是石油的泄漏对海洋造成的危害。故选C项[石油是另一个(引起人们)担心的主要原因]。
4.D 根据前句Rivers can als cntribute t the pllutin f ceans.和后句Fertilizers used n the farmlands may be carried t the cean...可知D项“很多河流接收来自农田的水”承上启下。故选D。
5.G 根据前句These chemicals slwly build up in fish and ther small animals.和后句The build-up f these chemicals in the animals can make them ill r cause their babies t be brn dead r sick.可知G项“然后这些动物把杀虫剂传给以它们为食的更大型的动物”承上启下,故选G。
【高频词汇】 1.bacteria (pl.)n.细菌 2.surrunding adj.周围的 3.expse v.使暴露;使体验;使接触 4.spill v.(使)洒出;溢出 5.cntribute t导致;促使;有助于
长难句分析
原句 Fertilizers used n the farmlands may be carried t the cean, where they cause a great increase in the number f certain plants.
分析 本句是一个主从复合句。where引导的是非限制性定语从句,先行词是the cean。Fertilizers后的used n the farmlands为过去分词短语作定语。
句意 农田里使用的肥料可能会被带入海洋,在海洋里,它们导致某些植物的数量大量增加。
Ⅲ.
One pssible versin:
Paragraph 1:
Appraching the drway, Jenny tk a deep breath. Tired and sad, she sat dwn in frnt f the huse. “Where might my mther be?” she wndered. “Was she really s angry with me that she didn't want t shw any care fr me?” Again, the scene f the quarrel appeared in her mind. She remembered her rudeness t her mther, and she just realized that all the sclding frm her mther was due t the fact that her mther really cared a lt abut her. Tears rlled dwn her cheeks.
Paragraph 2:
A gentle tuch n her hair called her mind back. She raised her head t see the familiar face and the wrried eyes. “Here yu cme! I've been lking fr yu.” Jenny culdn't help but thrw herself int her mther's arms. “I'm srry and thank yu fr all yu have dne fr me.” She expressed the sincere aplgy and the great gratitude. Then she felt the hug tightened.写作指导

1.文章第二段最后一句中提到“Jenny made up her mind t make an aplgy t her mther”,而且续写第一段开头句中提及Jenny到了家门口,那么Jenny会有什么行为和什么样的心理活动呢?
2.根据续写第二段首句中“called her mind back”可知本段应叙述Jenny的一些心理活动,配合一些动作描写。
Para. 2
A gentle tuch n her hair called her mind back.
1.是谁轻抚了Jenny的头发?是她的妈妈吗?如果是,续写第一段中就不可以提及“母女相见”的内容。
2.如果轻抚Jenny头发的人是妈妈,根据“gentle”一词体会妈妈的态度,她一定原谅了Jenny,那么第二段应该主要写母女二人的互动,最后冰释前嫌。
