古诗鉴赏形象鉴赏题题组训练

古诗鉴赏形象鉴赏题题组训练一、基础题组(一)人物形象题1.(2012·安徽)阅读下面这首诗，然后回答以下问题。

最爱东山晴后雪[注]只知逐胜忽忘寒，小立春风夕照间。

最爱东山晴后雪，软红光里涌银山。

注本诗为《雪后晚晴，四山皆青，惟东山全白，赋〈最爱东山晴后雪〉二绝句》中的一首。

请简要分析这首诗中诗人的形象。

答：________________________________________________________________________答案诗人只顾追寻胜景而不觉春寒，驻足春风夕阳中凝望东山，对东山雪景充满喜爱之情。

从这些动作与心理的描写中，能够看到一位心境悠闲、陶醉于自然美景而欣然忘我的诗人形象。

解析此题考查从欣赏诗歌抒情主人公形象方面来把握诗歌情感。

杨万里喜欢描写自然景物，这首七绝描写了早春雪后晚晴优美的山色，抒发了诗人陶醉于自然的美好情怀。

可通过题目“最爱”和诗中词语“逐胜”“忘寒”“最爱”归纳出诗人的形象特点。

2.阅读下面这首唐诗，然后回答以下问题。

过融上人兰若[注]綦毋潜山头禅室挂僧衣，窗处无人溪鸟飞。

黄昏半在下山路，却听钟声连翠微。

注融，诗人所要寻访的和尚的名字；上人，对和尚的尊称；兰若，梵语“阿兰若”的简称，指和尚的住所。

从诗的前两句来看，诗人所拜访的僧人是一个什么样的形象？请简要分析。

答：________________________________________________________________________答案诗人所拜访的是一个避世清修、洒脱清逸的高僧形象。

禅室建于山头，远离尘世，禅室无人，窗外溪流鸟飞，僧人不知何处而去；静谧幽雅的环境烘托出僧人的情趣高雅；“挂僧衣”的细节表达了僧人的悠闲洒脱。

(二)景物形象题3.(2008·宁夏、海南)阅读下面这首宋诗，然后回答以下问题。

高考语文总复习小说阅读环境描写分析题题组训练(1)

环境描写分析题题组训练一、基础题组1.试分析下面语段中环境描写的作用。

一时黛玉进了荣府，下了车。

众嬷嬷引着，便往东转弯，穿过一个东西的穿堂，向南大厅之后，仪门内大院落，上面五间大正房，两边厢房鹿顶耳房钻山，四通八达，轩昂壮丽，比贾母处不同。

黛玉便知这方是正经正内室，一条大甬路，直接出大门的。

进入堂屋中，抬头迎面先看见一个赤金九龙青地大匾，匾上写着斗大的三个大字，是“荣禧堂”，后有一行小字：“某年月日，书赐荣国公贾源”，又有“万几宸翰之宝”。

大紫檀雕螭案上，设着三尺来高青绿古铜鼎，悬着待漏随朝墨龙大画，一边是金蜼彝，一边是玻璃。

地下两溜十六张楠木交椅，又有一副对联，乃乌木联牌，镶着錾银的字迹，道是：座上珠玑昭日月，堂前黼黻焕烟霞。

下面一行小字，道是：“同乡世教弟勋袭东安郡王穆莳拜手书”。

原来王夫人时常居坐宴息，亦不在这正室，只在这正室东边的三间耳房内。

于是老嬷嬷引黛玉进东房门来。

临窗大炕上铺着猩红洋罽，正面设着大红金钱蟒靠背，石青金钱蟒引枕，秋香色金钱蟒大条褥。

两边设一对梅花式洋漆小几。

左边几上文王鼎匙箸香盒；右边几上汝窑美人觚——觚内插着时鲜花卉，并茗碗痰盒等物。

地下面西一溜四张椅上，都搭着银红撒花椅搭，底下四副脚踏。

椅之两边，也有一对高几，几上茗碗瓶花俱备。

其余陈设，自不必细说。

(节选自《林黛玉进贾府》) 答：________________________________________________________________________ 答案写出了贾府显赫的社会地位，显示了主人尊贵的社会地位和富贵荣华，表现出贾府确确实实“与别家不同”。

(2008·浙江)阅读下面的文字，完成文后题目。

乌米(俄)阿·马·高尔基乌米坐在门旁的石头上，她的身材匀称颀长，白发苍苍。

她那布满细小皱纹的脸，已被太阳晒成了棕褐色。

Others imagine it as the last really clean place left on earth. We have polluted the deepest oceans with plastic rubbish. "And now", CNN says "It's the Arctic's turn."German scientists have recently found micro-plastics in Arctic snow. Micro-plastics are pieces of plastic smaller than 5 millimeters. Sadly, the scientists found 1800 pieces of micro-plastics per liter of（每升）snow.How is plastic（垃圾）pollution reaching the Arctic? According to scientists, "It's clear that most of the micro-plastics in the snow come from the air." They fall off the plastic objects and are moved by the wind, just like dust. They mix with ice in the air and fall to the ground as snow. Finding these plastics in Arctic snow means that we may breathe them in.Are they bad for us? Scientists cannot answer this question for now, according to the WHO. We do know that our bodies cannot take in "large" pieces of micro-plastics. However, if the plastics are small enough, they can find ways into our bodies and stay there for a long time, which can be bad for our health. What's more, earlier studies have shown that micro-plastics may contribute to lung cancer risk.Micro-plastics have also been found in rivers and oceans around the world. Earlier research has found that they flow over long distances and into our oceans, hurting ecosystemsalong the way. They start in our waste water, then flow into rivers and out to the sea, where they are eaten by sea animals. If people then eat these animals, it means that we're eating the plastic as well.（1）We can learn from Paragraph 1 that ________.A.the Arctic is the last really clean place left on earthB.the Arctic is a beautiful icy land with clean airC.the Arctic has been polluted by plastic rubbish（2）The underlined word "contribute" means "________" in Chinese.A.增加B.捐献C.造成（3）Where do most of the micro-plastics in the snow come from?A.From water.B.From air.C.From wind.（4）Which of the following isn't true?A.Micro-plastics may cause lung cancer.B.We don't have to mind micro-plastics right now.C.Micro-plastics have hurt ecosystems.（5）How does the writer end this passage?A.By advising us to drink clean water.B.By asking people not to eat sea animals.C.By telling the seriousness of plastic pollution.9.Maria.I like milk and bananas I don't like hamburgers or French fies.
