That's human nature (but) ... we kind of get crazy sometimes and we don't know where it should stop.”Americans are connected at unprecedented (前所未有的) levels — 93% now use cell phones or wireless devices; one third of those are“smart phones” that allow users to browse the web and check e-mails, among other things. The benefits are obvious: checking messages on the road, staying in touch with friends and family, efficiently using time once spent waiting around. The downside:_often, we're effectively disconnecting from those in the same room.That's why, despite all the technology that makes communicating easier than ever, we often stop talking to one another. From texting at dinner to posting on Facebook at work or checking e-mails while on a date, the connectivity revolution is creating a lot of divided attention, not to mention social anxiety. Many analysts say it's time to step back and reassess (再评价)．“What we're going to see in the future is new opportunities for people to be plugged in and connected like never before，” says Scott Campbell. “It can be a good thing, but I also see new ways the traditional social construction is getting somewhat torn apart.”Our days are filled with beeps and pings — many of which pull us away from tasks at hand or face-to-face conversations. We may feel that the distractions (干扰) are too much, but we can't seem to stop posting, texting or surfing. “We're going through a period of adjustment and rebalancing，” says Sherry Turkle and she wants to remind peop le that technology can be turned off. “Our human purposes are to really have connections with people，” she says. “We have to reclaim it. It's not going to take place by itself.”1．According to Paragraph 1, Gretchen Baxter thinks ________.A．the new technology always influences people's life in a positive wayB．the new technology always influences people's life in a negative wayC．the family isn't that important compared to the new technologyD．people are too dependent on the new technology to let go2．The underlined word “downside” in Paragraph 2 probably means “________”．A．advantage B．weakness C．strength D．effect3．Which of the following is TRUE according to the passage?A．The wide use of mobile devices has nothing to do with the traditional social construction.B．Mobile devices play a less important part in American life.C．Mobile devices create a lot of divided attention and social anxiety.D．Many analysts speak highly of the wide popularity of mobile devices.4．What can be inferred from the last paragraph?A．Something must be done to get connection with people in reality again. B．Using mobile services can help people get connection with each other. C．Mobile services have a strong impact on people's life.D．The connection with people can happen naturally.Good communication is vital in modern society. We know that much of the communication is unspoken. Consciously or unconsciously, we show our true feelings with our eyes, faces, bodies and attitudes. Your good qualities can make good communication. The personal qualities include：physical appearance, energy, rate of speech, pitch and tone of voice, gestures, expressiveness of eyes, and the ability to hold the interest of others.What should we do so that our communication will be effective？Here are my suggestions.Firstly, you should be yourself. The trick is to be consistently you, at your best. The most effective people never change character from one situation to another. They're the same whether they're having a conversation with their close friends, addressing their garden club or being interviewed for a job. They communicate with their whole being.Secondly, whether you're talking to one person or one hundred, always remember to look at them. Don't break eye contact while talking. As you enter a room, move your eyes comfortably, then look directly at those in the room and smile. This shows clearly that you are at ease. Smiling is important. The best type of smile and eye contact is gentle and comfortable, not forced.You should also absorb other people before showing yourself. You can't learn anything when you talk. When you attend a meeting, a party or an interview, don't immediately start throwing your opinions.Stop for a second.Absorb what's going on.What's the mood of the others？Are they down, up, happy, expectant? Are they eager to learn from you, or do they show resistance? If you can sense what's happening with others, you will be better able to reach them. So, listen before you talk.The fourth suggestion is that you focus your energy. How do you get your energy up? Before the meeting, collect your thoughts about the goal of the meeting — yours and the others'. Once you go through the doorway, no longer think about yourself. Focus on the person you are meeting to find out what he is interested in. Properly collected energy comes across when we sincerely believe something. When you speak with energy, you are involved with your audience and your message. You create an air of certainty.The audience may disagree with you, but they can't question your belief.Lastly, I would like to remind you that you should lighten up. Take a good hard look at yourself.Do you say “I” too often? Are you only concentrated on your own problems? Do you complain frequently? If you answered yes to even one of these。

高二语文阅读限时训练(解析版)第4课 《论语》十二章《大学之道》《人皆有不忍人之心》
第4课《论语》十二章、大学之道、人皆有不忍人之心一、立足文本（一）阅读下面文字，回答问题。
孟子曰：“人皆有不忍人之心。
先王有不忍人之心，斯有不忍人之政矣。
以不忍人之心，行不忍人之政，治天下可运之掌上。
所以谓人皆有不忍人之心者，今人乍见孺子将入于井，皆有怵惕恻隐之心，——非所以内交于孺子之父母也，非所以要誉于乡党朋友也，非恶其声而然也。
由是观之，无恻隐之心，非人也；无羞恶之心，非人也；无辞让之心，非人也；无是非之心，非人也。
恻隐之心，仁之端也；羞恶之心，义之端也；辞让之心，礼之端也；是非之心，智之端也。
人之有是四端也，犹其有四体也。
有是四端而自谓不能者，自贼者也；谓其君不能者，贼其君者也。
凡有四端于我者，知皆扩而充之矣，若火之始然，泉之始达。
苟能充之，足以保四海；苟不充之，不足以事父母。
”1．下列加横线的词的解释，不正确的一项是( )A．皆有怵惕恻隐之心怵惕：恐惧。
B．非所以内交于孺子之父母也内：同“纳”，结交。
C．非所以要誉于乡党朋友也要：通“徼”，求取。
D．若火之始然，泉之始达然：……的样子。
【答案】D【解析】D项，然：同“燃”，燃烧。
2．下列句中加横线“之”的意义和用法，与例句相同的一项是( )例句:人之有是四端也A．若火之始然,泉之始达B．知皆扩而充之矣C．人皆有不忍人之心D．治天下可运之掌上【答案】A【解析】A项与例句都是结构助词,用在主谓之间,取消句子独立性。
B项,代词,代前文的“四端”。
C项,结构助词,的。
D项,代词,代“治天下”。
3．下列对原文有关内容的概括和分析，不正确的一项是（）A．孟子从人性的前提推导政治，从人人都有“不忍人之心”的仁心推导仁政，突出仁政应该是天经地义的。
B．孟子提出的“人皆有不忍人之心”是对孔子关于“人性”思想的进一步发展。
尤其在此基础上提出的“仁义礼智”，更是成了中国古代哲学中“性善论”的理论基础和支柱。
C．孟子指出“不忍人之心”是人生而固有的，承认“仁义礼智”是人的天性里固有的，体现了孟子朴素的唯物主义思想。

惠子．．贻我大瓠之种，我树之成，而实五石。
以盛水浆，其坚不能自举．．谓庄子曰：“魏王也。
剖之以为瓢，则瓠落无所容。
非不呺然大也，吾为其无用而掊之。
”庄子曰：“夫子固拙于用大矣！宋人有善为不龟手之药者，世世以洴澼絖④为事。
客闻之，请买其方百金。
聚族而谋曰：‘我世世为洴澼絖，不过数金；今一朝而鬻技百金，请与之。
’客得之，以说吴王。
越有难，吴王使之将，冬，与越人水战，大败越人，裂地而封之。
能不龟手一也，或以封，或不免于洴澼絖，则所用之异也。
今子有五石．之瓠，何不虑以为大樽．而浮于江湖，而忧其瓠落无所容，则夫子犹有蓬之心也夫！”惠子曰：“吾有大树，人谓之樗；其大本拥肿而不中绳墨，其小枝卷曲而不中规矩。
立之涂，匠者不顾。
今子之言，大而无用，众所同去也。
”庄子曰：“子独不见狸狌乎？卑身而伏，以候敖者；东西跳梁，不辟高下，中于机辟，死于罔罟。

一匹马两个人
迟子建
一匹老马拉着两个老人，朝二道河子方向走。
马是瘦马，走起路来就难免慢慢腾腾的。两个老人，是一对夫妻。老头子跟老马一样瘦，
老太婆则像个大树墩一样胖。他们都是小眼睛，是那种懒得睁开的、老是处在半梦半醒间
的小眼睛，尤其是老太婆。因而有的时候，马觉得老太婆是没长眼睛的人。
二道河子离他们居住的村庄有二十里路。这条路，马不知走了多少趟，也不知走了多少年，
只记得以前背上吃了主人数不清的鞭子。马还记得，他们的儿子第一次被人用手铐带走时，
哪怕是走在没有辎重的平道上，它也要挨上几十道鞭子。而他第二次戴着手铐被人带走后，
他们对它则温情多了，夜里不忘了喂点豆饼给它吃，女主人还常常用一把刷子给它理鬃毛，
仿佛把它当成了他们的儿子。
同以往一样，坐在车辕的男人垂着头袖着手打盹，车尾的老太婆则躺着睡觉。他们不用担
心马会走错路，因为去二道河子只这一条路。他们也不用担心马会受惊，因为这个季节没
有其他的车辆过来。马呢，它知道两个人都在迷迷糊糊地睡，所以它若遇见笔直的路段时，
也抽空打一下盹，它老是觉得累。
精忠中学高中 限时训练 文理 语文
高二语文第3页（共4页）
马打了一个响鼻，示意二道河子已经到了。果然，老头子下了车，他先用乎抚摩了一下汗
涔涔的马，无限怜惜地说：“唉，瞅瞅你这一身的汗，真让我不忍心再使唤你了。”说着，
他回头去看车尾的老伴。
“老太婆，你到哪里了，我看不见你，你给我个音呀!” 老头子叫道。
老头听不见老太婆的声音，他急了，仔细地看看周围，也不见人影。他这才明白，老太婆
丢了。他责备自己太粗心，边掉转车头，折回去寻找。
马听见老头呼唤老太婆，已经明白了。尽管它已经累得眼花缭乱了，还是加快了步伐。可
是老头还是嫌它走得慢，他没有鞭子，就下车折了一根柳条，不停地抽它。马虽然疼痛难
耐，但仍闷着头，拼命快走。老头子并不领情，心急火燎地持续抽它。
大约走了四里路，他们发现了老太婆，她横躺在路上。老头叫了一声：“你怎么睡在路上
了，吓死我了。”
马满身是汗，疼痛难忍，四条腿没有一条不在打哆嗦。它不像老头子那么乐观。
果然，老头子发现老太婆的额头都是血，而地上也是血迹斑斑。老头试了试她的鼻息，一
点呼吸都没感觉到，再摸她那双粗糙的手，已经冰凉如秋日的河水。
当老头子看见路面有一块凸出来的像笋尖一样的带有血迹的石头时，他咆哮着，使劲踢那
石头，而石头就龇着血红的牙望着老头子。老头子从车上取下镐头，奋力砸那石头，石头
迸溅出一串串火花，瞬间分崩离析。
他们朝那村庄走去。
一块这么不起眼的石头就要了她的命，老头子想不明白。她落地后是不是呼唤他了？可惜
他耳朵不如年轻时灵便了，而且马车一旦走起来，听到的只是马蹄声。他这样一想，就有
些怨恨马了。
而马呢，也走得心事重重。它在责备自己。一定是因为它走路不如以往利索，腿常常抖一
下，车也随之颠簸一下，想必她就是这么被颠在地上的。而且，在拉扯的过程中少了分量，
它应该有所觉察的，可它什么也没有察觉到。它是个废物了。马觉得自己最好就此不要吃
草了，就这么完结算了。
老马就在那一天水草未尽，老头子也是粒米未食……
