语文2020年八年级上册寒假作业答案

语文2020年八年级上册寒假作业答案语文寒假学案一一.基础积累1.略2.B3.①拈轻怕重②见异思迁③纯粹4.D 5C. 6.A 7.迥鉴宛湃二、阅读理解：1.B 2.B 3.②⑦⑩ 4.①⑧⑨ 5.突出了白的精神，强调要向白求恩同志去学习的必要，有力地证明了论点 6.对工作的极端负责任，对同志对人民的极端的热忱7.白求恩同志毫不利己……的热忱从前线回来的人……无不为之感动语文寒假学案二一、1.C 2.D 3.A 4.C 5.结出丰硕的果莲能纹丝不动，扎根大地二、阅读理解(一)1.《论语》知道它的人比不上喜爱它的人，喜爱它的人比不上对它有兴趣的人。

《论语》他(孔子)做人是发愤读书忘记了吃饭，沉浸在学习的快乐中而忘记了忧愁，甚至不知道自己将要老了，如此而已。

“人能从自己的职业中领略出趣味，生活才有价值。

”第二句话以孔子为例证明以事业为乐的生活才最有意义。

2.B 3.要乐业做工好苦四凡职业都是有趣味的 4.承接上文，总起下文语文寒假学案三一、思考：1.人与人相处，要多一些宽容。

2.与人相处,要多一些宽容——为什么要多一些宽容——怎么样才能做到宽容(总分结构) 3.要做到宽容，就必须做到互谅、互让、互敬、互爱。

4.四者有一个逐层递进的关系。

“互谅、互让”是宽容的最基本的要求，“互敬、互爱”则是进一步的高要求，尤其是互爱，则是最根本的一点。

只有互爱才能真正做到“互谅、互让、互敬”。

5.不是，它是文章观点的补充论证。

如果不分青红皂白地一味强调宽容的重要性，可能会导致对丑恶甚至罪恶的姑息，要明辨是非、分清敌我，该批评、惩罚的还是要批评、惩罚。

这样,文章做到了既旗帜鲜明，又滴水不漏。

6. 讲道理。

为什么要多一些宽容——怎么样才能做到宽容，宽容要避免什么情况。

文中阐述互谅、互让、互敬、互爱是使用了对比方法，告诉我们应该怎样做，不应该怎样做。

引用林则徐名言7.略二、填空1.①海纳百川，有容乃大。

山高万仞，无欲则刚。

[语文八年级上册寒假作业答案2020]八年级上册寒假作业

[语文八年级上册寒假作业答案2020]八年级上册寒假作业参考答案第一部分(略)第二部分练习一：略练习二：略练习三：阅读一：《小石潭记》1、pâihuányíchùcēncīxīdǒuqiǎochuàngcīliáoyǎnjiǎnpíjùn2、清澈;左右，表示约数;愣住的样子;忽然;像北斗星一样曲折;离开;背，顶;在;主谓之间，不翻译;3、⑴青葱的树木，翠绿的茎蔓，覆盖着，缠绕着，摇动着，连缀着，参差不齐，随风飘荡⑵向小石潭的西南方望去，(只见)小溪像北斗星那样曲曲折折，像蛇爬行那样蜿蜒，忽明忽暗，忽隐忽现。

⑶因为这里的环境太凄清，不可以久留，就题字离去4、本文是按游览的先后顺序来写景抒情的。

文中突出地表现了“小石潭”全石为底、潭水清澈、竹树环合、环境凄清等特点。

5、开头的心情是快乐的，这从作者“闻水声，如鸣佩环，心乐之”以及对游鱼的那种“似与游者相乐”的描写可知;最后的心情又是凄凉忧伤的，这从“寂寥无人，凄神寒骨”的描写可知。

6、乐是忧的另一种表现形式。

柳宗元参与改革，失败被贬，心中愤懑难平，因而凄苦是他感情的主调，而寄情山水正是为了摆脱这种抑郁的心情;但这种欢乐毕竟是暂时的，一经凄清环境的触发，忧伤悲凉的心情又会流露出来。

7、写小丘所处位置及小丘的形貌8、例：文中描绘景物用了多种修辞手法，如“其石之突怒偃蹇，负土而出，争为奇状者，殆不可数。

”用了拟人的修辞手法，“其嵚然相累而下者，若牛马之饮于溪;其冲然角列而上者，若熊罴之登于山。

”则用了对偶和比喻的修辞手法，突出了小丘的奇特风光，展现了永州一带山水的特点，写得生动、形象、传神。

阅读二：1.B2.C点拨：第11题和第12题都是积累题，考查平时积累的文言知识，理解文言实词的意思。

解释文言实词，必须考虑词的古今异义和一词多义，并联系上下句来理解。

这两题都是选择题，要学会先运用排除法排除不符合要求的选项。

2020年八年级人教版上册政治寒假作业答案

2020年八年级人教版上册政治寒假作业答案1.A2.B3.B4.A5.B6.D7.C8.B9.C 10.A 11.D 12.A 13.C14.B 15.D 16. B 17.D 18.A 19.A 20.C 21.AD 22BD 23.CD 24.AD25.BC26.李红这种做法是不对的。

1她故意让老师难堪是对老师没有礼貌的表现，这种做法很容易伤害师生感情。

2李红应该礼貌地用商量的语气提醒老师，用恰当的方式指出老师错误。

27.启示：1与异性相处，要增强自我保护意识，掌握自我保护方法。

2中学生要慎交朋友，要乐交诤友，不交损友。

3青少年要提升法律意识，提升自控水平和抵抗不良诱惑水平，做到遵纪守法。

28.此观点是错误的。

1人无完人，朋友难免有缺点。

人各不同，朋友之间难免有分歧。

所以我们学会欣赏他人、赞美他人，宽容他人、尊重差异、增强沟通，我们就会交到更多有趣的朋友，获得更为持久友谊。

2但如果为了照顾朋友的情面做违反道德、法律等违心事这是不准确的，真正的友谊应该是坦诚的，在原则面前一定要坚定，不能以牺牲原则为代价维持所谓的朋友。

3可见友谊需要忠诚去播种，热情去灌溉，原则去培养，谅解去护理。

29.镜头一和镜头四是男女生正常交往,镜头二和镜头三不是。

1镜头一和镜头四，男女生之间的交往坦然大方，真诚待人，体现了同学们之间的互相关心和协助，这样的交往能学习对方优点，完善自己个性，增加性别意识，促动身心健康发展和提升学业成绩。

2镜头二和镜头三，男女生之间的交往方法不对，因为男女同学交往应该在集体活动中展开，不宜只在个别人之间建立，应尽量扩大交往范围，尽量避免只与单个异性或几个异性交往。

总之男女同学之间交往既需要互相尊重，又要自重自爱;既要开放自己，又要掌握分寸;既要主动热情，又要注意交往的方式、场合、时间和频率。

30. (1)采访、问卷调查、数据统计、座谈会等(2)原因;1受传统师生关系影响把老师看做，而自己更多地扮演着遵从者的角色造成师生之间的隔阂，影响师生交往。
