toast,smiled at my mom and asked me how my day at school had been.I don't remember what I told him that night.But I remember watching him put butter on that toast.He ate it up as usual.After dinner,I remember hearing my mom apologize to my dad for burning the toast.I'll never forget what he said:"Honey,I love burnt toast."Later that night,I went to kiss daddy good night.I asked him if he really liked his toast burnt,He wrapped(紧抱)me in his arms and said:"Your mommy worked very hard today.She's really tired.And a bit of burnt toast never hurt anyone!"Life is full of imperfect things.Nobody is

的承受者,所以用被动语态,一般现在时被动语态的构成是:主语+am/is/are+动词的过去分词,故选C.【点评】本题考查时态和语态.每个时态都有标志词,熟记这些标志词是做题的关键.在没有时间状语的情况下可以根据语境来对时态做出判断.判断语态的关键则是观察主语是谓语动词的执行者还是承受者.29.(1分)Every morning the old people enjoy______ in the

的承受者,所以用被动语态,一般现在时被动语态的构成是:主语+am/is/are+动词的过去分词,故选C.【点评】本题考查时态和语态.每个时态都有标志词,熟记这些标志词是做题的关键.在没有时间状语的情况下可以根据语境来对时态做出判断.判断语态的关键则是观察主语是谓语动词的执行者还是承受者.29.(1分)Every morning the old people enjoy______ in the

故天将降大任于是人也,必先苦其心志,劳其筋骨,饿其体肤,空乏其身,行拂乱其所为,所以动心忍性,曾益其所不能。

11.解释下列句中加线的实词。

(2分)(1)行拂乱其所为拂:(2)入则无法家拂士拂:12.解释下列句中加线的虚词。

(2分)(1)管夷吾举于士于:(2)曾益其所不能其:13.用现代汉语翻译“故天将降大任于是人也,必先苦其心志,劳其筋骨,饿其体肤,空乏其身”一句。

(2分)14.文章中列举六位名人的事例有何作用?15.本文的中心论点是“_________________”(选用文中句子回答)四、现代文阅读(共30分)(一)阅读《大自然的语言》(节选),回答问题。

(15分)大自然的语言竺可桢①立春过后,大地渐渐从沉睡中苏醒过来。

冰雪融化,草木萌发,各种花次第开放。

再过两个月,燕子翩然归来。

不久,布谷鸟也来了。

于是转入炎热的夏季,这是植物孕育果实的时期。

到了秋天,果实成熟,植物的叶子渐渐变黄,在秋风中簌簌地落下来。

北雁南飞,活跃在田间草际的昆虫也都销声匿迹。

到处呈现一片衰草连天的景象,准备迎接风雪载途的寒冬。

在地球上温带和亚热带区域里,年年如是,周而复始。

②几千年来,劳动人民注意了草木荣枯、候鸟去来等自然现象同气候的关系,据以安排农事。

杏花开了,就好像大自然在传语要赶快耕地;桃花开了,又好像在暗示要赶快种谷子。

布谷鸟开始唱歌,劳动人民懂得它在唱什么:“阿公阿婆,割麦插禾。

”这样看来,花香鸟语,草长莺飞,都是大自然的语言。

③这些自然现象,我国古代劳动人民称它为物候。

物候知识在我国起源很早。

古代流传下来的许多农谚就包含了丰富的物候知识。

到了近代,利用物候知识来研究农业生产,已经发展为一门科学,就是物候学。

物候学记录植物的生长荣枯,动物的养育往来,如桃花开、燕子来等自然现象,从而了解随着时节推移的气候变化和这种变化对动植物的影响。

④物候观测使用的是“活的仪器”,是活生生的生物。

它比气象仪器复杂得多,灵敏得多。

物候观测的数据反映气温、湿度等气候条件的综合,也反映气候条件对于生物的影响。

应用在农事活动里,比较简便,容易掌握。

物候对于农业的重要性就在这里。

下面是一个例子。

⑤北京的物候记录,1962年的山桃、杏花、苹果、榆叶梅、西府海棠、丁香、刺槐的花期比1961年迟十天左右,比1960年迟五六天。

根据这些物候观测资料,可以判断北京地区1962年农业季节来得较晚。

而那年春初种的花生等作物仍然是按照往年日期播种的,结果受到低温的损害。

如果能注意到物候延迟,选择适宜的播种日期,这种损失就可能避免。

……⑥物候学这门科学接近生物学中的生态学和气象学中的农业气象学。

物候学的研究首先是为了预报农时,选择播种日期。

此外还有多方面的意义。

物候资料对于安排农作物区划,确定造林和采集树木种子的日期,很有参考价值,还可以利用来引种植物到物候条件相同的地区,也可以利用来避免或减轻害虫的侵害。

我国有很大面积的山区土地可以耕种,而山区的气候、土壤对农作物的适应情况,有很多地方还有待调查。

为了便利山区的农业发展,开展山区物候观测是必要的。

⑦物候学是关系到农业丰产的科学,我们要进一步加强物候观测,懂得大自然的语言,争取农业更大的丰收。

16.阅读第一段指出下列句子中加线词语的表达效果。

(4分)(1)立春过后,大地渐渐从沉睡中苏醒过来。

(2)冰雪融化,草木萌发,各种花次第开放。

再过两个月,燕子翩然归来。

17.为什么“古代流传下来的许多农业就包含了丰富的物侯知识。

”一句中的“许多”不能删去?(2分)18.结合第四段的内容,说说“物候对于农业的重要性就在这里。

”一句中的!“这里”具体指的是什么?(2分)19.结合第三四段的内容,指出下列各句分别运用了什么说明方法?有何作用?(4分)(1)物候学记录植物的生长荣枯,动物的养育往来,如桃花开、燕子来等自然现象,从而了解随着时节推移的气候变化和这种变化对动植物的影响。

说明方法:作用:(2)它比气象仪器复杂得多,灵敏得多。

说明方法:作用:20.阅读第六段,请具体说说本段是按什么顺序进行说明的。

(3分)(二)阅读张保振的《交友之道》一文,回答问题。

(15分)交友之道①俗话说:“在家靠父母,出门靠朋友”,说明朋友的重要。

《诗•小雅》言:“虽有兄弟,不如友生”,说明朋友的至要。

《孟子•滕文公上》载:“出入相友”,说明朋友的必要。

朋友的重要、至要、必要,在古人看来,是“友也者,友其德也”的。

所以,与朋友交,就要只取其长,不计其短。

也就是说,交友要有选择,看重并学习朋友的优良品德。

②那么在现代生活中,我们又该怎样交友呢?③交友之道首先是择友。

不是什么人都可以成为朋友的。

对朋友,古人们看得很重,认为是“五伦之一”,是“平居可与共道德,缓急可与共患难。

”并认为,“友则两相关切。

若酒肉饮博,相与往还,此党也,非友也。

”(蒲松龄语)所以,择友,就要或道同相助,或品德相亲,或学问相成,或气节相感,或然诺相信,或才技相合,或诗文相尚等,要两相共赢,昭昭可鉴。
