第一部分、积累与运用语文知识积累与运用题号知识点考察方式分值1字音辨析选择题3分2字形辨析选择题3分3成语运用选择题3分4病句辨析选择题3分5语言得体选择题3分6名著阅读主观题5分一、1、【参考答案】B【答案解析】慰藉(jiè)/嫉妒(jí);告罄(qìng)/惟吾德馨(xīn)考点:字音辨析难点与易错点:①形近字读音(“炫”与“眩”;“罄”与“馨”;“缀”与“辍”;“粹”与“猝”)②习惯性误读,“辍”(chuò)易读成zhuì,“炽”(chì)易读成“zhì”,“藉”(jiè)易读成“jí”攻关建议:多读多用,把常读错的抄进错题本,常常翻看。
2、【参考答案】C【答案解析】A“人声顶沸”应为“人声鼎沸”、“搏学多才”应为“博学多才”B“家瑜户晓”应为“家喻户晓”、“妇儒皆知”应为“妇孺皆知”D“禁固思想”应为“禁锢思想”、“张惶失措”应为“张皇失措”。
此题注意“器宇轩昂”与“气宇轩昂”都是对的。
考点:成语、字形难点与易错点:对成语的熟悉度,辨析同音字与形近字。
攻关建议:可按意思记忆字形。
如“人声鼎沸”中“鼎”是古代的一种铜铸的锅,用来煮东西的。
而“鼎沸”的意思是人群的声音吵吵嚷嚷,就像锅中的水烧开了,发出大声响。
“博学多才”指学问广博精深,有多方面的才能。
“博”是“广博”,自然不是“搏斗”的“搏”。
3、【参考答案】D【答案解析】眼花缭乱:缭乱:纷乱。
形容眼前的景象复杂纷繁,使人感到迷乱不清。
也比喻事物复杂,无法辨清。
既然已经“眼花缭乱”了,又岂会“清晰真切”?前后矛盾。
考点:成语运用难点与易错点:辨析容易望文生义的成语攻关建议:翻阅较权威的中考备考书,总结自己平常容易用错的成语,重点标记或者抄在小本子上,多看。
若对某个成语有疑问,要及时翻阅字典,以便准确记忆并且加强记忆。
4、【参考答案】C【答案解析】分类不当。
