心游客能够和狼一起散步,故选D。

答案:D

5.解析:推理判断题。根据第二段第四、五句可知,尽管狼已完全适应了和人待在一起。但是他们是野生动物;又根据本段最后两句“For that reason,Shelley and Casey explained,the walk is totally on the wolf's terms.‘We don't approach them,but if they come up to us,we can touch them.’”可推知,和狼散步可能存在潜在的危险。

答案:A

6.解析:细节理解题。根据第三段最后一句中的“apparently she was saying hello in wolf talk”可知,Flora的举动显然是在用狼的说话方式表达问候,因此B项正确。

答案:B

7.解析:推理判断题。根据最后一段第二句“But the purpose...but they'd rather avoid people,for the most part”可推知,Casey和Shelley组织这个冒险旅行的目的是澄清一些关于狼的守旧观点。

答案:D

C

(2019·潍坊高三模拟)Plants cannot run or hide,so they need other strategies to avoid being eaten.Some curl up their leaves,others produce chemicals to make themselves taste bad if they sense animals drooling on them,chewing them up or laying eggs on them—all signals of an attack.New research now shows some flora can feel a plant-eating animal well before it launches an attack,letting a plant prepare a preemptive (先发制人的) defense that even works against other pest species.

When ecologist John Orrock of the University of Wisconsin -Madison sprayed snail slime—a liquid the animals release as they slide along—onto soil,nearby tomato plants appeared to notice.They increased their levels of an enzyme (酶),which is known to prevent plant-eating animals.“None of the plants were ever actually attacked,”Orrock says.“We just gave them cues that suggested an attack was coming,and that was enough to cause big changes in their chemistry.”

Initially Orrock found this defense worked against snails; in the latest study,his team measured the slimy warning's impact on another potential threat.The investigators found that hungry caterpillars(毛虫) ,which usually eat tomato leaves greedily,had no appetite for them after the plants were exposed to snail slime and activated their chemical resistance.This nonspecific defense may be a strategy that benefits the plants by further improving their overall possibilities of survival,says Orrock,who reported the results with his colleagues in March in Oecologia.

The finding that a snail's approach can cause a plant response that affects a different animal made Richard Karban curious,a plant communications expert,who was not involved in the study.“It is significant that the plants are responding before being damaged and that these cues are having such far-ranging effects,”Karban says.The research was comprehensive,he adds,but he wonders how the tomato plants felt chemicals in snail slime that never actually touched them.

“That's the million-dollar question,”Orrock says.He hopes

future research will make out the mechanisms that enable plants to sense these relatively distant cues.

8.John Orrock sprayed a liquid onto soil near tomato plants to__________.

A.make them grow better B.give them a warning

C.keep plant-eating animals away D.inform plant-eating animals of danger

9.Why is the example of “caterpillars” mentioned in Paragraph 3?

A.To introduce another animal. B.To confirm the result of the study. C.To appeal to people to protect animals. D.To analyze different resistance chemicals. 10.What does Richard Karban really want to know? A.How tomato plants become aware of danger. B.What the chemicals in the snail slime are. C.Whether the research is of practical value. D.What the finding of the research is. 11.What can be a suitable title for the text? A.Watchful Plants B.Greedy Animals C.A Snail's Approach D.A Defense Attack 体裁:说明文 题材:科学研究 主题:警觉的植物

【语篇解读】 本文主要介绍了一项新的科学研究。研究表明植物会对外在威胁相当警觉,会自动作出反应进行自我保护。

8.解析:推理判断题。根据第二段最后一句“‘We just gave them

cues that suggested an attack was coming,and that was enough to cause big changes in their chemistry.’”可推知,John Orrock在西红柿植株附近的泥土上喷洒液体的目的是给予植物一种警告,让它们能够产生自我保护性反应,且其与第三段第一句中的“...his team measured the slimy warning's impact on another potential threat”呼应,故选B。

答案:B

9.解析:推理判断题。根据第三段第一句“Initially Orrock found this defense worked against snails;in the latest study,his team measured the slimy warning's impact on another potential threat”可推知,文章中提到毛虫的例子是为了验证研究的结果,故选B。

答案:B

10.解析:推理判断题。根据第四段最后一句“The research was comprehensive,he adds,but he wonders how the tomato plants felt chemicals in snail slime that never actually touched them”,并结合对最后一段的整体理解可推知,Richard Karban实际上想了解的是西红柿植株是如何意识到危险的,故选A。

答案:A

11.解析:标题判断题。根据文章中的关键词plant,并结合对全文的整体理解可推知,本文主要讲述的是有关植物的科学研究,研究发现植物有对外在威胁或攻击的自我保护性反应,故选A。

答案:A Ⅱ.阅读七选五

(2019·唐山高三质量检测)I did not go on my first hike until my mid-30s.I could blame it on the fact that I grew up on the Great Plains of South Dakota and North Dakota.__1__Having never gone,I didn't see the value and always shook my head when asked.

__2__At the urging of my wife,and with my two young kids,we walked a beautiful forest path on a cool August morning.I carried a small backpack with water and snacks(小吃).When we reached the top,we ate lunch together overlooking a perfectly still pond and a scenic Vermont.

A few weeks ago,my 11-year-old son,my 61-year-old dad,and I hiked Camelback Mountain in Phoenix.Last weekend,I hiked down the Grand Canyon with my son along the South Kaibab Trail.And later this week,my wife and daughter will join us to walk the Waterfall Trail in the White Tank Mountains.__3__ Now,just to be clear,by no means would I classify myself as all expert hiker.__4__And I have no plans to climb Mount Kilimanjaro or walk the Appalachian Trail.But waking early on a Saturday morning to walk 3-5 miles along a forest path with lunch in the backpack is a journey I'd recommend to anyone.

It is healthy physical exercise that creates wonderful memories.__5__And given the chance,hiking teaches us important truths about life.

A.Most of our hikes only last 2 hours. B.I've fallen in love with climbing mountains. C.I love the stillness and calm of an empty path. D.But mostly,to be honest,I just wasn't interested. E.If you can climb a mountain,you can do anything.
