24.讀下列的材料,思考並完成下列問題。(12分)
材料:細心的人會注意到,兩年前的10月,我國第一艘載人飛船神舟五號發射成功。今年神舟六號的發射,又逢金秋時節,難道是巧合嗎?不是。這是因為秋季的氣象條件,最適合我國發射載人飛船。
飛船發射季節的選擇,要考慮到各種可能影響到發射的因素,其中氣象條件是最直接、最關鍵的決定因素。
飛船上天後,要由航天測控網對飛船實施測控管理。我國的航天測控網由多個地面測控站和4艘遠望號航天測量船組成。這4艘測量船分別是太平洋上的「遠望」一號和「遠望」二號測量船,印度洋上的「遠望」四號測量船,大西洋上的「遠望」三號測量船。其中,3艘測量船都在緯度相對較高的南半球。
南半球的季節正好與我國相反。我國的春夏季節在南半球是秋冬季節,海況很惡劣,即使正常航行都難保安全,更不用說在海上執行測控任務了,因此不宜發射飛船。我國的秋冬季節在南半球是春夏季節,海況較好,便於航行和執行測量任務。因此,我國神舟一號至五號飛船的發射時機都選在與南半球相反的秋冬季節。(宜昌日報)
(1)影響「神舟六號」發射的因素中,最直接、最關鍵的決定因素是 ;
(2)飛船上天後,要由航天測控網對飛船實施測控管理。我國4艘遠望號航天測量船實行測控的地點在 、 、 ;其中有3艘遠望號航天測量船在 半球 緯度地區。
(3)「神舟六號」為什麼要在秋季發射?(2分)
(4)「神舟六號」發射要考慮天氣和氣候的條件;我們的日常生產、生活也離不開天氣和氣候。請你試舉兩個事例說明天氣和氣候與我們的生產、生活的關系。(4分)
25.讀「全球候鳥遷徙路線圖」及相關材料,回答問題。(19分)
材料一: 在周邊國家紛紛「中招」後,中國也終於未能倖免,此次禽流感為何來勢如此洶洶?它是怎樣傳播擴散的?專家分析,此次禽流感,極有可能與遷徙候鳥參與傳播有關。一般通過兩種途徑傳染,一是通過禽肉、禽蛋等禽產品的流通進行傳播,另一種就是通過飛禽傳播,主要是通過大量攜帶病毒的候鳥遷徙進行傳播。當攜帶病毒的野鴨、大雁等候鳥往南遷徙過冬時,其帶有病毒的糞便及分泌物會污染遷徙沿途的水源、土壤等環境,當地禽類一旦接觸帶有病毒的環境,便會感染禽流感,並波及與之接觸的人類。(新浪網)
材料二: 1878年以來,禽流感的暴發頻率呈幾何級數增加,使人們不得不思考其中原因。首先,隨著社會和科技的進步,人們對於疾病的關注更勝從前,同時由於流通渠道的方便和快捷,信息共享的程度更高了,一些流行疾病由於人們的關注而顯得發生得更加頻繁。但是不可否認,人類的活動確實在不斷改變著自然,改變著人類所有能夠觸及的生態環境。禽流感近年來的頻繁暴發確實和人類對環境的改變有著一定的關系。(CCTV-農業頻道)
(1)讀「全球候鳥遷徙路線圖」,候鳥遷徙的路線中經過中國的有
條;找出其中候鳥經過大洲、大洋最多的一條路線,並將大洲、大洋的名稱寫出來:
、 、 、 、 、 、 。
(2)圖中不可能發生禽流感的大洲是 。
(3)認真閱讀材料:此次禽流感的傳播途徑是什麼?(2分)
(4)「人類的活動確實在不斷改變著自然,改變著人類所有能夠觸及的生態環境。禽流感近年來的頻繁暴發,確實和人類對環境的改變有著一定的關系。」結合你在地理課中所學到的人口與環境的關系的知識,談談你對這句話的理解?(8分)

7. 仁愛 七年級上冊 100~104頁答案
1、把200千米的水引到城市中來,這個任務交給了甲,乙兩個施工隊,工期50天,甲,乙兩隊合作了30天後,乙隊因另有任務需離開10天,於是甲隊加快速度,每天多修0.6千米,10天後乙隊回來,為了保證工期,甲隊速度不變,乙隊每天比原來多修0.4千米,結果如期完成。問:甲乙兩隊原計劃各修多少千米?
解:設甲乙原來的速度每天各修a千米,b千米
根據題意
(a+b)×50=200(1)
10×(a+0.6)+40a+30b+10×(b+0.4)=200(2)
化簡
a+b=4(3)
a+0.6+4a+3b+b+0.4=20
5a+4b=19(4)
(4)-(3)×4
a=19-4×4=3千米
b=4-3=1千米
甲每天修3千米,乙每天修1千米
甲原計劃修3×50=150千米
乙原計劃修1×50=50千米
2、小華買了4支自動鉛筆和2支鋼筆,共付14元;小蘭買了同樣的1支自動鉛筆和2支鋼筆,共付11元。求自動筆的單價,和鋼筆的單價。
解:設自動鉛筆X元一支 鋼筆Y元一支
4X+2Y=14
X+2Y=11
解得X=1
Y=5
則自動鉛筆單價1元
鋼筆單價5元
3、據統計2009年某地區建築商出售商品房後的利潤率為25%。
(1)2009年該地區一套總售價為60萬元的商品房,成本是多少?
(2)2010年第一季度,該地區商品房每平方米價格上漲了2a元,每平方米成本僅上漲了a元,這樣60萬元所能購買的商品房的面積比2009年減少了20平方米,建築商的利潤率達到三分之一,求2010年該地區建築商出售的商品房每平方米的利潤。
解:(1)成本=60/(1+25%)=48萬元
(2)設2010年60萬元購買b平方米
2010年的商品房成本=60/(1+1/3)=45萬
60/b-2a=60/(b+20)(1)
45/b-a=48/(b+20)(2)
(2)×2-(1)
30/b=36/(b+20)
5b+100=6b
b=100平方米
2010年每平方米的房價=600000/100=6000元
利潤=6000-6000/(1+1/3)=1500元
4、某商店電器櫃第一季度按原定價(成本+利潤)出售A種電器若干件,平均每件獲得百分之25的利潤。第二季度因利潤略有調高,賣出A種電器的件數只有第一季度賣出A種電器的6分之5,但獲得的總利潤卻與第一季度相同。
(1)求這個櫃台第二季度賣出A種電器平均每件獲利潤百分之幾?
(2)該櫃台第三季度按第一季度定價的百分之90出售A種電器,結果賣出的件數比第一季度增加了1.5倍,求第三季度出售的A種電器的利潤比第一季度出售的A種電器的總利潤增加百分之幾?
解:(1)設成本為a,賣出件數為b,第二季度利潤率為c
那麼利潤=a×25%=1/4a
第二季度賣出電器5/6b件
第一季度的總利潤=1/4ab
第二季度利潤=ac×5/6b=5/6abc
根據題意
1/4ab=5/6abc
c=1/4×6/5
c=3/10=30%
(2)第一季度定價=a(1+25%)=5/4a
第三季度定價=5/4a×90%=9/8a
第三季度賣出(1.5+1)b=2.5b件
第三季度的總利潤=9/8a×2.5b-2.5ab=5/16ab
第三季度比第一季度總利潤增加(5/16ab-1/4ab)/(1/4ab)=(1/16)/(1/4)=0.25=25%
5、將若干只雞放入若干個籠中。若每個籠中放4隻,則有一隻雞無籠可放;若每個籠中放5隻,則恰有一籠無雞可放,那麼,雞、籠各多少?
設雞有x只,籠有y個
4y+1=x
5(y-1)=x
得到x=25,y=6
6、用白鐵皮做罐頭盒,每張鐵皮可製成盒身25個,或制盒底40個,一個盒身和兩個盒底配成一套罐頭盒,現有36張白鐵皮,用多少張制盒身,多少張制盒底可以使盒身與盒底正好配套?
分析:因為現在總有36張鐵皮製盒身和盒底.所以x+y=36.公式;用制盒身的張數+用制盒底的張數=總共製成罐頭盒的白鐵皮的張數36.得出方程(1).又因為現在一個盒身與2個盒底配成一套罐頭盒.所以;盒身的個數*2=盒底的個數.這樣就能使它們個數相等.得出方程(2)2*16x=40y
x+y=36 (1)
2*16x=40y (2)
由(1)得36-y=x (3)
將(3)代入(2)得;
32(36-y)=40y
y=16
又y=16代入(1)得:x=20
所以;x=20
y=16
答:用20張制盒身,用16制盒底.
25、從A城到B城,水路比陸路近40千米,上午11時,一隻輪船以每小時24千米的速度從A城向B城行駛,下午2時,一輛汽車以每小時40千米的速度從A城向B城行駛,輪船和汽車同時到達B城,求A城到B城的水路和陸路各多長?
解:設水路a千米,陸路b千米
a+40=b(1)
a/24-3=b/40(2)
(1)代入(2)
a/24-3=(a+40)/40
1/60a=4
a=240千米
b=240+40=280千米
水路240千米,陸路280千米
注意:上午11時到下午2時相差3個小時
26、某汽車在相距70千米的甲乙兩地往返行駛,由於路程中有一個坡度均勻的小山,所以去時用時2.5小時,返回使用時2.3小時,已知汽車在平地上每小時行駛30千米,下坡時每小時行駛40千米,上坡時每小時行駛20千米,求的上坡路,下坡路及平地的路程?
解:設去時上坡a千米,下坡b千米,則平路是70-a-b千米
a/20+b/40+(70-a-b)/30=2.5(1)
a/40+b/20+(70-a-b)/30=2.3(2)
(1)-(2)
a/40-b/40=0.2
a-b=8
a=b+8代入(1)
解得
b=4千米
a=12千米
所以去的時候平路70-4-12=54千米,上坡12千米。下坡4千米
1.兩車站相距275km,慢車以50km/一小時的速度從甲站開往乙站,1h時後,快車以每小時75km的速度從乙站開往甲站,那麼慢車開出幾小時後與快車相遇?
設慢車開出a小時後與快車相遇
50a+75(a-1)=275
50a+75a-75=275
125a=350
a=2.8小時
2.一輛汽車以每小時40km的速度由甲地開往乙地,車行3h後,因遇雨,平均速度被迫每小時減少10km,結果到乙地比預計的時間晚了45min,求甲 乙兩地距離。
設原定時間為a小時
45分鍾=3/4小時
根據題意
40a=40×3+(40-10)×(a-3+3/4)
40a=120+30a-67.5
10a=52.5
a=5.25=5又1/4小時=21/4小時
所以甲乙距離40×21/4=210千米
3、某車間的鉗工班,分兩隊參見植樹勞動,甲隊人數是乙隊人數的 2倍,從甲隊調16人到乙隊,則甲隊剩下的人數比乙隊的人數的 一半少3人,求甲乙兩隊原來的人數?
解:設乙隊原來有a人,甲隊有2a人
那麼根據題意
2a-16=1/2×(a+16)-3
4a-32=a+16-6
3a=42
a=14
那麼乙隊原來有14人,甲隊原來有14×2=28人
現在乙隊有14+16=30人,甲隊有28-16=12人
4、已知某商店3月份的利潤為10萬元,5月份的利潤為13.2萬元,5月份月增長率比4月份增加了10個百分點.求3月份 的月增長率。
解:設四月份的利潤為x
則x*(1+10%)=13.2
所以x=12
設3月份的增長率為y
則10*(1+y)=x
y=0.2=20%
所以3月份的增長率為20%

There are many beautiful flowers in the yard, too. I can also go fishing and swimming in the river near my home. I think the life in the countryside is very interesting. Do you think so?
Please write to me soon.

V. Hello, my name is Tim. That』s my good friend, Michael. He is very smart. When he was five, he could ride a bike and write. But I couldn』t. I could swim and draw at the age of five. Now we are in the same class. We often play ball games together. Michael is good at playing basketball while I do well in soccer. We hope we can be in the Olympic Games one day.

IV. Dear Jack,
I』m very glad to get your letter. You want to know about the weather in Hainan. Now let me tell you. The weather here is very good all year around. Spring lasts from March to May. It』s very warm. Sometimes it rains , but not heavily. Summer begins in June. It』s a very hot season. The sun shines brightly every day. People like wearing sunglasses and shorts. Fall comes after summer. The weather gets a little cool, but the leaves don』t turn yellow and they seldom fall from the trees. December, January and February are in winter. It isn』t cold at all. It』s my favorite season. You can see green trees and red flowers here and there. It never snows in Hainan, so I can』t make snowmen. If you want to come here, you』d better come in winter. I am sure you』ll have a good time.
