AI’ve often wondered if I might do more good as a travel agent rather than as a psychologist. It seems that I have been more dramatically affected by certain kinds of travel experiences than I ever have.My trip to Iceland is a fine example of that. The plan was to spend two days in a remote mountain hut in Iceland. I was working on a photographic book about winter in Iceland and needed to capture images of this amazing region of high mountain peaks, smoky volcanoes, and lakes with floating icebergs.The moment after we arrived, the weather turned extreme making visibility impossible. It snowed so much and the wind bl ew so hard that we couldn’t leave the tiny hut. To stay warm, we walked around in circles much of the day inside the tiny hut. We tried to call for help but the radio did not work. Day after day, we watched our supplies of food and fuel grow dangerously short. We got acute cabin fever (幽居病) and started going for walks and ski expeditions outside. Even when the weather finally broke, nobody came to get us even though it was three days beyond our scheduled pickup. By the time the rescue team came to pull us out, we had all given up hope.From then on, the world looks different to me, as does my life. It would have taken me years of psychotherapy to get to the same point.Almost everyone has a story to tell, and interestingly, most of these experiences were not altogether pleasant at the time. In fact, it appears that the most constructive life-changing journeys were those that involved some sorts of awful and uncomfortable events that forced the person to develop new resources, increase confidence, and solve problems in new ways.21. The writer went to Iceland to ______.A. enjoy the natural beautiful floating icebergsB. take photos about the region for a bookC. collect materials for psychological researchD. challenge the high mountains there22. During the trip in Iceland, those travelers faced difficulties EXCEPT that ______.A. they got lost in the mountainB. they were short of food and fuelC. they couldn’t see the surroundings clearlyD. they failed to get in touch with the rescue team23. From Paragraph 3, we learn that the travelers ______.A. were in despair before they were rescuedB. stayed in the hut for three days altogetherC. got sick because of going for ski outsideD. got rescued immediately the weather turned fine24. Which of the following statements is true according to the passage?A. The writer is a travel agent who loves difficult challenges.B. In Iceland the weather is always extreme and it snows a lot.C. The travellers were so depressed that they needed psychotherapy.D. Awful journeys may become life-changing events that inspire people.BOne of India’s top engineering schools has restricted Internet access in its boarding houses, saying addiction to surfing, gaming and blogging was affecting students’ performance, making them lonely and even suicidal.Authorities at the best Indian Institute of Technology (IIT) in Mumbai said students had stopped socializing and many were late for morning classes or slept through them. “Now, a student doesn’t even know who lives two doors away from him because he is so busy on the Internet,” said Prakash Gopalan, dean of Student Affairs. “The old dormitory culture of companionship and socializing among students is gone. This is not healthy in our opinion.”IIT-Mumbai, with about 5,000 students, is one of the seven IITs across India which are considered to be among the finest engineering schools in the world. They are also a talent pool for global technology giants. But their hard courses, tough competition and lonely campus lifestyle have taken an effect on students. Depressive and dysfunctional lifestyles are known to be common among IIT students, and at least nine have committed suicide inthe past five years. Students have unlimited free Internet access in their boarding houses to help them in their studies, but many also use it to surf, chat, download movies and music, blog and for gaming.“Starting Monday, Internet access will be banned between 11 p.m. and 12:30 p.m. at IIT­Mumbai’s 13 boarding buildings to encourage students to sl eep early and to try and force them out of their shells.” Gopalan said. But the move has not gone down well with students who say they hate their lives being regulated. “Now they will say we need to listen to a lullaby (摇篮曲) to go to sleep.” said Rajiv, an electronics student.25. According to the text, the students addicted to the Internet in IIT-Mumbai are likely to ______.A. perform well in studiesB. participate in social activitiesC. know their classmates betterD. feel lonely and even suicidal26. The underlined word “dysfunctional” in Paragraph 3 most probably means “______”.A. unpopularB. meaningfulC. abnormalD. exciting27. What measures have been taken in IIT-Mumbai?A. Students must go to bed before 11 p.m.B. Students are forbidden to surf the Internet on campus.C. Students have unlimited free Internet access in their dormitories.D. Internet access is unavailable in deep night in boarding buildings.28. We may infer from the last paragraph that ______.A. all electronics students hate the banning orderB. some students complain about the banning orderC. there is no Internet access on the IIT campus ever sinceD. more students prefer listening to music to surfing the InternetCWell, parents, surprise! Lots of us are using Twitter and Facebook to thumb rides, and not just to school. It’s awkward to be refused when you call a friend and ask for a ride. But with Twitter, you just look for other people heading the same way.It may sound risky, so many teens stay wi thin their own social circles to find rides, and don’t branch out beyond friends when asking on Twitter just like me, but to some young people, especially those taking longer trips, stranger danger is less of a concern.“I think the digital connection of y oung people is really key, because younger generations grew up sharing things on line, sharing files, photos, music, etc, so they’ve been very used to sharing,” said Juliet Schor, a sociology professor at Boston College.The sharing economy got big during the recession (经济衰退), allowing people to access more goods, services using technology and even to share costs. And that technology, for me, is what the car was for my mom, a gateway to more freedom, like what my friend Earl says, “The symbol of freedom isn’t the car any more because there’s technology out there connecting you to a car.”According to the researchers at the University of Michigan, 30 years ago, eight in ten American 18-year-olds had a driver’s license compared to six in ten today. So it’s not that surprisin g that on my 16th birthday I wasn’t rushing to get a license but an iPhone.“Driving, for young people, does mean they have to disconnect from their technology, and that’s a negative. So if they could sit in the passage side and still be connected, that’s going to be a plus.” Schor continued.To me, another plus is that ridesharing represents something, something much bigger than trying to save money. I see it as evidence that people still depend on each other. My generation shares their cars and apartments the way neighbors used to share cups of sugar. For the system to work, some of us still need our own cars. But until I get my own version of the silver Super Beetle, you can find me on Twitter.29. The American teens like me, prefer to possess an iPhone as a birthday gift because _______.A. it is most fashionable and coolB. they are bored with driving carsC. they are fond of being connectedD. it is much cheaper than a car30. We can learn from the text that _______.A. Twitter is a website for teens to make friends and achieve goalsB. ridesharing can be seen as a sign that people still count on each otherC. driving cars for teens means a plus and connecting with technologyD. having a car and cost-sharing symbolize more fre edom for the author’s mother31. Professor Juliet would agree that _______.A. young people will sit waiting to be contacted by reading a passageB. sharing economy is bound to be responsible for the recessionC. young people tend to share a car with strangers by means of TwitterD. being connected via technology comes first for young people32. The best title for the passage is probably _______.A. Twitter, an Awesome WebsiteB. Cars or iPhoneC. Teens Use Twitter to Thumb RidesD. Cool Teens on the GoDNews that Microsoft made a $44.6 billion bid to buy Yahoo resulted in heated discussions made by many Internet users. Here are some responses:Diane Burke of Weeks bury, KentuckyI think it would definitely be an interesting combination. Everyone recognizes the names Yahoo and Microsoft, but everyone also says, “Did you Google it?” Such a catchphrase (时髦话) is going to be hard to beat. Shaun Carney of Laurelville, OhioI think the merger (合并) will provide more competitions for Google. I don’t think the merger will allow Microsoft to develop faster than Google, though. I believe the increased competition this merger brings will force Google to stay on top of its game by offering more fresh and original Internet tools and expanding on the tools it already offers.Toni Suarez of Hacienda Heights, CaliforniaI view the merger as a necessary element in preventing a monopolization (垄断). Perhaps it would bring better high technology innovations to e-mail and help in researching and developing a better Internet!Rick R. of Edgewater, FloridaIt sounds like a disaster to me. If this were to happen, I would stop using my Yahoo e-mail account because I don’t like the feeling of Microsoft spying upon my business. I will sign up for Google.Antonio Glosser of Kansas City, MissouriRight now, Yahoo offers a lot of features and tools at no cost for all different levels of Internet users. Micr osoft seeks nothing but profit. Undoubtedly, they’ll do nothing other than find ways to start removing Yahoo’s formerly non-priced features. Microsoft’s greed will ruin the great thing that Yahoo currently is.33. How many companies are mentioned in the passage?A. One.B. Two.C. Three.D. Four.34. Which of the following statements is NOT true according to the passage?A. Shaun’s attitude towards Google is passive.B. Toni believes the Internet will have a promising future.C. Rick will support Google after the merger.D. Antonio is afraid that the merger will cost Yahoo’s free features.35. The passage is mainly about ______.A. opinions on the merger of Yahoo and MicrosoftB. the strengths of Yahoo and MicrosoftC. the strengths and weaknesses of large companiesD. the future of Yahoo and Microsoft第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

2024届东北三省三校（哈师大附中、辽宁省实验中学、东北师大附中）高三第二次联合模拟考试语文试卷一、现代文阅读阅读下面的文字，完成小题。

材料一：《红楼梦》后四十回续书作者问题不是“新闻”，实实在在是“旧闻”。

张庆善指出，早在2008年《红楼梦》新校本第三次修订出版时，就已经由“曹雪芹、高鹗著”改为“曹雪芹著，无名氏续，程伟元、高鹗整理”了。

张庆善认为曹雪芹其实把《红楼梦》写完了，理由是：从创作规律而言，曹雪芹创作《红楼梦》批阅十载，增删五次，纂成目录，分出章回，历时十年之久，不可能只写出前八十回就不再往下写了，翻来覆去只修改前八十回，这不符合创作规律；现有的大量脂砚斋批语，已经透露出八十回以后的情节，曹雪芹的亲友脂砚斋、畸笏叟都已经看到了这些稿子，如庚辰本第四十二回回前批：“钗玉名虽二个，人却一身，此幻笔也。

今书至三十八回时已过三分之一有余，故写是回，使二人合而为一。

请看黛玉逝世后宝钗之文字，便知余言不谬矣。

”曹雪芹《红楼梦》写完了，原稿八十回后为什么没有传下来？张庆善认为是《红楼梦》传阅时弄丢了。

曹雪芹逝世后，畸笏叟保存残稿，更不敢轻易拿去给别人看，怕再弄丢，最终八十回后的稿子也随着畸笏叟的去世而成了永远的谜案。

在曹雪芹逝世后的二三十年里，《红楼梦》都是以八十回本在社会上流传，直到1791年，程伟元、高鹗整理出版了一百二十回本《红楼梦》，才结束了《红楼梦》以八十回本流传的时代。

那么，《红楼梦》后四十回是从哪里来的？张庆善认为，后四十回是程伟元多年搜寻得来的，程伟元邀请高鹗帮助修订整理，高鹗欣然答应，“细加厘剔，截长补短”，依据就是程伟元、高鹗为程甲本、程乙本出版所写的序和引言。

张庆善认为，高鹗只是整理者之一，到目前为止所有关于高鹗续写后四十回的根据都不成立，而且在程伟元、高鹗刊刻程甲本以前，就有《红楼梦》一百二十回抄本存在，高鹗也没有时间去写。

对于后四十回，有人认为主要是曹雪芹原稿的散稿，有人认为其中没有曹雪芹一个字。

Thanks for helping me. 10.Some time ago, a friend of mine who worked in a part of the city I didn’t know very well, invited me to call on him. It took me hours to get there and I took great trouble to find a proper spot to park my car. As I was already three-quarters of an hour late, I parked my car quickly.At noon, just as I was leaving my friend’s office, it suddenly struck me that I had no idea where I had parked my car. I could hardly go up to a policeman and tell him that I had lost a small green car somewhere ! Walking down street after street, I examined each car closely and was very happy to see a small green car just behind an old car. But how disappointed I was to discover that though the car was exactly like my own, it belonged to someone else! Feeling quite tired now, I went off for lunch. Some time later, I left the restaurant and walked down the street. Turning the corner, I nearly jumped for joy: my car was right in front of me, and there was no problem this time.To tell the truth, driving in crowded cities is far from being a pleasure and it is much easier to walk than to drive.。

一、单选题1. 某同学想自己设计并改装一个欧姆表。

他手上有如下器材：量程300μA 、内阻900Ω的电流计；电动势1.5V 的一节干电池；滑动变阻器、电阻箱和若干定值电阻。

他设计的电路如图甲所示，实验时他将两表笔短接，电流计指针满偏时，他计算出电路中的总电阻为5kΩ。

然后他将一个50Ω和10Ω的电阻分别接到两表笔之间时，发现电流计指针指示的位置几乎一样，很难区分。

经过研究后他认为，要想比较准确地测量几十欧姆的电阻，用图甲所示电路并不合适，为此他设计了如图乙所示的电路。

并联合适电阻 R ₂后，使干路电流是流经电流计电流的100倍。

则（ ）A ．将图乙电路中的两表笔短接，此时电路中的总电阻是5ΩB ．分别将一个50Ω和10Ω的电阻先后接到图乙电路的两表笔之间，通过干电池的电流几乎没有区别C ．分别将一个50Ω和10Ω的电阻先后接到图乙电路的两表笔之间，电流计指针指示的位置明显不同D ．在图甲电路和图乙电路的两表笔之间分别接入5kΩ和50Ω的电阻，通过两电流计的电流明显不同2.如图甲所示，正方形硬质金属框放置在磁场中，金属框平面与磁场方向垂直。

磁感应强度B 随时间t 变化规律如图乙所示。

在0~0.2s 的时间内与0.2s~0.6s的时间内（ ）A ．通过金属框的电荷量之比为2∶1B ．金属框中电流的电功率之比为4∶1C ．金属框中产生的焦耳热之比为4∶1D ．金属框两边受到安培力方向相反，大小之比为3∶13. 通过实验研究通电长直导线间的相互作用规律。

如图所示，为两根平行的长直导线，通过外接直流电源分别给两导线通以相应的恒定电流。

为导线所在平面内的两点。

下列说法中正确的是（ ）A．两导线中的电流大小相等、方向相反时，点的磁感应强度为零B ．导线电流向上、导线电流向下时，导线所受安培力向右C ．点的磁感应强度一定不为零D ．两导线所受安培力的大小一定相等4. 加速度传感器是一些智能手机上配备的较为实用的软件，能显示物体运动过程中的加速度变化情况。
