答题技巧
二、名词单复数的误用及近义词的混用考点剖析此类题的错误设置一般包括以下几个方面: 1.可数名词单复数形式误用 2.可数名词与不可数名词的混用 3.用于固定词组中的一些名词的用法 4.同义词或反义词的混用 5.名词指代上下文单复数不符方法突破 1.理清可数与不可数名词之间的区别与联系 2.记清一些用于固定词组中的名词的特殊用法 3.结合语境认真分辨同义名词或近义名词
解题策略
2.重点关注 (1)关注该题所涉及的一致性问题:主要包括主谓一致,时态、语态一致,代词指代一致,名词的数与格的一致,句式结构与语意一致, 行文关系的一致等。 (2)关注词性问题:了解主要词类的语法作用及其在句中的经常性位置。如:名词在句中一般做主语、宾语、表语;动词做谓语;形容词充当表语、定语和宾语补足语;副词则充当状语,修饰形容词、动词乃至句子。 (3)关注固定搭配:主要考查介词与动词、名词、形容词的固定搭配;副词与动词的固定搭配;及物动词后多介词或副词以及不及物动词后少介词,英语中的一些固定句型与习惯搭配等。

2024年高考语文第二轮专题复习强化训练：语言文字运用(附答案) (1)

2024年高考语文第二轮专题复习强化训练：语言文字运用阅读下面的文字，完成下题。

事有凑巧，在不同的时间和不同的地方，我听见过三位老师讲“破釜沉舟”这个成语。

第一位教师是这样讲的：“‘破釜沉舟’表示坚决的意思。

做事一定要坚决。

无论做什么，只要是正当的、应该做的事，就必须抱定只许前进而不许后退、只许胜利而不许失败的决心，只有这样才能得到成功。

如果(______________)，工作还没开始就准备下失败的退路，那样一定不会成功。

①当然，②前进的目的必须正确。

③在这一点上，④我们不能跟古人相提并论。

由于时代的局限，古人，尤其是封建统治阶级的人，做事的目的在今天看来很多是成问题的，下定决心做好事是应当的，如果坚决做坏事，那就不应当了。

”第二位教师是另一种讲法，他说：“‘釜’就是锅，‘舟’就是船。

‘破’和‘沉’都是动词。

‘破釜’是‘使釜破’的意思，也就是把锅砸碎；‘沉舟’是‘使舟沉’的意思，也就是把船凿沉。

这样用法的动词叫作‘使动词’。

同是做饭的工具，古代叫‘釜’，现代叫‘锅’；同是水上运输工具，古代叫‘舟’，现代叫‘船’；这是古今词汇的演变。

像古代叫‘冠’，现代叫‘帽子’，古代叫‘履’，现代叫‘鞋’，都是这种情形。

曹植《七步诗》里有‘豆在釜中泣’的句子，______________，这里的‘釜’和‘舟’跟‘破釜沉舟’里的‘釜’和‘舟’意思相同。

”第三位教师讲得比较简单，话说得比较少。

他这样讲：“项羽渡河进攻秦朝的军队，渡河之后，把造饭的锅砸碎，把船凿沉，断了自己的退路，以示有进无退的决心，终于把秦军打败了。

后来大家就用‘破釜沉舟’这个成语表示下定最大的决心，不顾任何牺牲的意思。

”1．将下列俗语填入文中括号内，恰当的一项是（）A．干打雷不下雨 B．又吃鱼又嫌腥C．前怕狼后怕虎 D．首尾不能兼顾2．文中画线的语句中有一处表述不当，请标出原句序号后再做修改，并使修改后的语句与上下文的衔接流畅自然。

3．请在横线处仿照上句补写恰当的句子，要求内容正确贴切，语意完整连贯。

到官，以大姓公孙丹为五官掾。

丹新造居宅，而卜工以为当有死者，丹乃令其子杀道行人，置尸舍内，以塞其咎。

宣知，即收丹父子杀之。

丹宗族亲党三十余人，操兵诣．府，称冤叫号。

宣以丹前附王莽，虑交通海贼，乃悉收系剧狱，使门下书佐水丘岑尽杀之。

青州以其多滥，奏宣考岑，宣坐征诣廷尉。

在狱，晨夜讽诵，无忧色。

及当出刑，官属具．馔送之，宣乃厉色曰：“董宣生平未曾食人之食，况死乎！”升车而去。

时同刑九人，次应及宣，光武驰使驺骑特原．宣刑，且令还狱。

遣使者诘宣多杀无辜，宣具以状对，言水丘岑受臣旨意，罪不由之，愿杀臣活岑。

使者以闻，有诏左转宣怀令，令青州勿案岑罪。

岑官至司隶校尉。

后江夏有剧贼夏喜等寇乱郡境，以宣为江夏太守。

到界，移书曰：“朝廷以太守能擒奸贼，故辱斯任。

今勒兵界首，檄到，幸思自安之宜。

”喜等闻，惧，即时降散。

外戚阴氏为郡都尉，宣轻慢之，坐免。

后特征为洛阳令。

时湖阳公主苍头白日杀人，因匿主家，吏不能得。

及主出行，而以奴骖乘，宣于夏门亭候之，乃驻车扣马，以刀画地，大言数．主之失，叱奴下车，因格杀之。

主即还宫诉帝，帝大怒，召宣，欲箠杀之。

宣叩头曰：“愿乞一言而死。

”帝曰：“欲何言？”宣曰：“陛下圣德中兴，而纵奴杀良人，将何以理天下乎？臣不须箠，请得自杀。

”即以头击楹，流血被面，帝令小黄门持之，使宣叩头谢主，宣不从，强使顿之，宣两手据地，终不肯俯。

主曰：”文叔①为白衣时，藏亡匿死，吏不敢至门。

今为天子，威不能行一令乎？”帝笑曰：“天子不与白衣同。

”因敕强项令出。

赐钱三十万，宣悉以班诸吏。

由是搏击豪强，莫不震栗，京师号为“卧虎”。

歌之曰：“枹鼓不鸣②董少平”。

在县五年。

年七十四，卒于官。

诏遣使者临视，唯见布被覆尸，妻子对哭，有大麦数斛、敝车一乘。

帝伤之，曰：“董宣廉洁，死乃知之！”以宣尝为二千石，赐艾绶，葬以大夫礼。

拜子并为郎中，后官至齐相。

（《后汉书·董宣传》）【注】：①文叔：光武帝刘秀字文叔②枹鼓不鸣：没有人击鼓鸣冤。

B．董宣在任江夏太守时先发文书告诫夏喜一伙，促使他们自动“降散”，而不是一味诛杀，他先礼后兵从而收到了水到渠成的效果。

然而他对待外戚很轻慢，遭致免官。

C．董宣对下属有爱护之心，水丘岑因杀宗党身陷囹圄，董宣声言是奉自己的命令，主动担当责任，而不推诿。

他曾把得到的三十万赏钱全部分发给部下。

D．文章详略得当，情节波澜起伏，生动地刻画了董宣刚直不阿、公正廉洁的典型形象，文中的董宣对豪强狠，对自己严，对部属宽，形象丰满。

窍门（苏联）左琴科著阎树声译现在住旅馆可真难哪，这是谁都知道的事。

我一到了南方，立即就深有感触。

一下轮船，我就快步直奔旅馆。

旅馆的守门人对我说：“现在的旅客可真奇怪，一下轮船，就都朝我们这儿奔，可是我们这里已没有闲房间了，全都客满。

”没有别的办法，我只好耍个花招，再碰碰运气吧。

离开旅馆，我一边走一边琢磨法子。

我手里拿着两件东西：一件是普通的提篮，另一件确实是个挺漂亮的钢板手提箱——其实就是个三合板箱子。

我把提篮暂存在卖报人那儿，然后把身上穿的那件从外国进口的大衣反穿了起来，大衣的方格里子就成为大衣面。

我又把便帽低低地压在鼻梁上，买了支雪茄烟叼在嘴上。

我就这么个打扮，提着那只出口的钢板手提箱，大模大样地再次闯进了那家旅馆。

守门人对我说：“先生！您不用进去了，里面没有空房间。

”我没理他，走近一个服务员的眼前，操起半通不通的外国话说：“一个、房间的、有？”服务员自言自语地说：“我的上帝啊！外国佬来啦！”接着，他也用半通不通的外国话回答说：“是，是的，一个、房子的、可以的、有，有。

请，请。

我这就给您腾房间，尽可能找个好房间，臭虫少一些的。

”表面上我装得神气十足，其实两条腿却在哆嗦着。

这个服务员挺爱扯外国话，于是他又问：“对不起，先生！请原谅。

您是德国人，还是别的哪国人呢？”我心中暗想：真糟糕，万一这个服务员懂德国话可咋办呢？于是，我对他说：“我是西班牙。
