神舟十二號飛行乘組出征太空,讓很多青少年對航天事業(yè)燃起了強烈的興趣和好奇心。中國青年報社對2047名14-35歲青少年進行了專項調(diào)查,結(jié)果圖示如下:
首先,林冠層就像一把大傘,能夠?qū)Υ怪苯涤赀M行再分配。一部分降水被林冠截留,直接蒸發(fā)到大氣中;一部分順著枝葉、樹干流到林地,形成樹干徑流。據(jù)統(tǒng)計,我國主要森林生態(tài)系統(tǒng)的林冠截留率平均值為11%~34%。
Ibelieved that I was right and he was wrong, and Tony believed that I was wrongand he was right. Our teacher, a kind and smart lady, decided to teach us alesson. She brought us to the front of the class and placed him on one side ofher desk and me on the other. In the middle of her desk was a large and roundobject. I could clearly see that it was black. The teacher asked us what colorthe object was. “White,” Tony answered. I couldn’t believe he said the objectwas white! “Clearly, it was black!” Another argument started between Tony andme, this time about the color of the object.

TheChinese knot, a folk art, has a long history. People first made them to recordinformation and send messages before they started to use words. The knots wereused for decoration (裝飾) and to express thoughts and feelings in theTang Dynasty. They were later popular in the Ming and Qing dynasties. But thisart wasn’t really accepted by the common people until the Qing Dynasty.
Flying kites Kites have quite a long history. The earliest kites were made ofwood, instead of paper. Nowadays, the three most famous kites are the Beijingkite, Tianjin kite, and Weifang kite. And they are quite different from eachother. For example, the swallow-shaped kite is a well-known Beijing style.

材料三 每當人們在中國的文獻中查找一種具體的科技史料時,往往會發(fā)現(xiàn)它的焦點在宋代,不管在應用科學方面還是在純粹科學方面都是如此?!袊目萍及l(fā)展到宋朝,已呈巔峰狀態(tài)。在許多方面實際上已經(jīng)超過了18世紀中葉工業(yè)革命前的英國或歐洲的水平?!ㄓⅲ├罴s瑟《中國科學技術史》
材料一 朝廷在故都(東京開封)時,實仰東南財賦,而吳中又為東南根柢,語曰:“蘇湖熟,天下足”。——摘自《陸游集》41.材料一描述的這種現(xiàn)象出現(xiàn)在哪一時期?“蘇湖熟,天下足”反映了這一時期的什么特征?(4分)
自省的力量,首先在于可以“”。古人云“以責人之心責己,則寡過”“日省其身,有則改之,無則加勉”,極言自省是修身養(yǎng)性、提升境界的重要方法?!妒勒f新語》載,周處年少時兇強俠氣,為鄉(xiāng)里所患,與蛟、虎并稱為“三害”。周處射虎殺蛟三日不見,鄉(xiāng)人以為周處死了互相慶賀,周處回來后聽到鄉(xiāng)鄰相慶,才知被鄉(xiāng)鄰憎惡,乃“有自改意”,由此棄惡從善,“有文思,志存義烈,言必忠信克己”。今天,我們講自省,對思想、工作、生活點滴及細節(jié)予以檢視,客觀地看待自我,清醒地查找不足,其意義并非止于懺悔,而在于超越自我,促進自我認知、自我完善,不斷喚醒善意良知,不斷升華人格。
現(xiàn)代人睡眠質(zhì)量差的原因主要來自工作壓力和電子產(chǎn)品兩方面。近日,一篇名為《毎天2點睡覺,37歲年輕父親查出胃癌晩期》的文章引起人們關注。主人公劉凌峰是有名的“拼命三郎",業(yè)務多、壓力大,幾乎毎天都是凌晨兩點之后才睡覚,最拼的一次是連續(xù)工作70個小時沒有合過眼。像他這祥熬夜晩睡的人在全球范圍內(nèi)都較為普遍。另外,睡眠質(zhì)量差的人。有許多都是電子產(chǎn)品的重度依賴者?;ヂ?lián)網(wǎng)從業(yè)者睡眠質(zhì)量普遍較差;自媒體人和程序員是失眠最嚴重的人群。網(wǎng)約車司機、快遞員和廣告人的睡眠質(zhì)量也普遍較差。同時,有四分之一的人失眠是因為玩手機。
車行一小段路程,我總覺得有點不大對勁,上好的馬路,車身卻微微顛簸,而且,車輪不是滑行向前,而是向前一沖,片刻的停頓之后,再向前一沖。我正覺奇怪,突然發(fā)現(xiàn)蹬車的人只有一條腿!右腿上一截黃黃的褲管,挽一個疙瘩,懸在空中,隨車輪向前“沖”的頻率前后晃蕩著。他的左腿用力地蹬著踏板,臀部時時脫離坐墊,身子向左傾斜,以便把所有的力量都用在左腿上,從他左腿并不肥大的褲管隨風擺動的情形,我猜想他唯一的好腿一定搜得可憐。
通常而言,即便是同一種植物,冬季和夏季的抗凍能力也不一樣在夏季活動期多不耐寒,在冬季休眠期則更為耐寒。這是因為春夏季節(jié),植物生長旺盛,養(yǎng)分消耗多于積累,因而其抗凍能力較弱。如北方的梨樹,在-30~-2℃低溫下能平安越冬,在春天卻抵擋不住微寒的襲擊;松樹的針葉,冬天能耐30℃的嚴寒,夏天如果人為地降溫到一8℃就會凍死,就是這個道理。
地名他很熟習,即使有時候繞點遠也沒有多大關系,好在自己有的是力氣。拉車的方法,以他干過的那些推、拉、扛、挑的經(jīng)驗來領會,也不算十分難。況且他有他的主意:多留神,少爭勝,大概總不會出了毛病。至于講價爭座,他的嘴慢氣盛,弄不過那些老油子們。知道這個短處,他干脆不大到“車口兒”上去;哪里沒車,他放在哪里。在這僻靜的地點,他可以從容的講價,而且有時候不肯要價,只說聲:“坐上吧,瞧著給!”他的樣子是那么誠實,臉上是那么簡單可愛,人們好像只好信任他,不敢想這個傻大個子是會敲人的。即使人們疑心,也只能懷疑他是新到城里來的鄉(xiāng)下老兒,大概不認識路,所以講不出價錢來。以至人們問到:“認識呀?”他就又像裝傻,又像耍俏的那么一笑,使人們不知怎樣才好。
有一年的春天,我因為脊椎側(cè)彎沒有得到完全矯正,再加上長時間久坐,經(jīng)常腰背疼得坐立難安。因別人介紹認識了家在重機廠的李醫(yī)生,便下定決心好好治療。每天下了班就開車到重機廠李醫(yī)生家。剛好是三月,風暖起來,花開成片,如同有人在潑灑顏料一般,醉人的酒紅,少女明艷的桃紅,嬰兒般純凈的粉白,這邊染一塊,那邊染一塊。到李醫(yī)生家,要經(jīng)過農(nóng)大門口一條筆直的路,兩旁種滿重瓣晚櫻,這個時節(jié),花團錦簇,觸目驚心。一直以來,我總是回避從這里經(jīng)過,農(nóng)大總是提醒我心里的疼痛,讓我想起弟弟,想起他在這里生活的歲月。我的弟弟,曾在這里學習,后來,他得了癌癥,發(fā)現(xiàn)時已是晚期,治療了半年多,還是離開了。弟弟開始治療也是在三月。爸爸的朋友在醫(yī)院對面有一套小房子,弟弟暫時住在這里,我每天下了班過去。
到超市買東西,看到標簽上的薄荷二字會無端升騰起莫名的親切感。生活日用品,不知道什么時候都換成了薄荷味的。出門時手包里會塞上一小包薄荷味的口香糖,并不為吃,只為能常??窗b上那片綠綠的薄荷葉。有一回,在居住附近的集市上碰到賣花人,這賣花人特別,竟只賣一種植物,是薄荷!天太熱,他把一盆盆青郁郁的薄荷小心放在剛下過雨的淺水溝里。水溝雖不太千凈,可那薄荷卻越發(fā)的青茂。我站在一旁看得癡,那一盆盆薄荷,在記憶里綿延開來,延展為一條明亮的鄉(xiāng)路,通往那無憂無慮簡單清寂的鄉(xiāng)村歲月。
十年前的那天,華北平原正吹著暖風,一片蔥綠,槐花花事已過。清晨,約幾位朋友登泰山,望不盡的奇峰峻嶺,一派令人驚嘆的“青未了”!約行兩小時,艱難的盤山道走過,迎面而來的是一片開闊地,中天門到了!令人驚喜的是,在平原已過了季節(jié)的槐花,在中天門竟以漫山遍野的燦爛迎接我:花若有待!我知道,槐花隱忍著推遲她的花期,等著我的到來。
