When today's moms and dads were kids，exploring nature meant creating an ant farm or making a mud pie．But with hot topics like environment，green and organic，today's little kids will need to become little environmentalists．It's time to get started in the backyard．
“Nature Discovery in My Backyard”is the first book in a series of children's books by The Little Environmentalists．LLC．The book is written for preschoolers and early readers． This picture book follows a little girl discovering what everyone sees，when they stop to look and smell the roses．A falling leaf，a beautiful flower or grass under feet become nature lessons．
“Children will smell，hear，feel and see their way through their own backyard nature discovery，”explains Rebecca Mattano，creator of “The Little Environmentalists”．“Each page gives a new and special look into nature with colorful pictures．It not only teaches but challenges children to find all that nature shows．”
To help parents and educators with their“green”lessons，the book gives tips on nature for every season of the year．Interesting educational facts on plants and animals are introduced in the back of the book．How many adults can name the animal family that the groundhog(土撥鼠)is in? You might be surprised to learn that it's the squirrel family．
The groundhog digs its home underground．They dig about 700 pounds of soil out of the ground when they are making their homes and can finish this in one day．They are in the squirrel family．
“My hope is for these books to build environmental knowledge，”adds Mattano．
The book introduces plenty of easy-to-do outdoor activities led by teachers and parents．

Susan Dahl had spent four months homeless in Colorado and just been on a painful 10-hour bus trip through ice and snow．Hungry and broke，she was anxious to get back to family in Minnesota．That's when a tall man in a red coat and red hat sat next to her at the downtown bus station，talked to her quietly and then gave her $100 on that December afternoon．The man was doing the work of Larry Stewart，Kansas City's original Secret Santa who wandered city streets handing out $100 bills to those who looked like they needed money．Stewart died of cancer at the age 58 earlier this year，but his spirit lives on．“Here's a $100 bill … and this is in memory of Larry Stewart，”said Dahl,56．
During about a quarter century， Stewart quietly gave out more than $1.3 million to people in streets，restaurants，bus stations，shelters and markets，saying it was his way of giving back at Christmas for all the wealth and generosity(慷慨)he had received in his lifetime．For years，Stewart did not want his name known or want thanks，but last December he acknowledged who he was and used his last few months while battling cancer to press his message of kindness toward others．He even trained some friends in the ways of Secret Santa．This Christmas，a friend who told Stewart in the hospital that he would carry on for him is out on the streets，handing out $100 bills，each one stamped with“Larry Steward，Secret Santa”Between Kansas City and several other cities this Christmas，the new Secret Santa will give away $75,000 of his own money，mostly in $100 bills．
“I didn't want to be a Secret Santa，”said the man，a businessman who lives in the Kansas City area．“I wanted to give Larry money．But last year he said I had to hand it out myself．So I did and got hooked．Anyone can be Secret Santa，”he says．“You don't have to give away $100．You can give away kindness．Help someone．”
45．We can learn from the passage that Larry Stewart
A．lived in Kansas city of the US B．gave away $1,300,000 openly
C．died of heart attack in hospital D．was fifty-six years old this year
46．The underlined word“broke”in Paragraph 1 probably means

In most situations ，light helps us see. But when it comes to looking at the night sky, light is actually a kind of pollution.
It stops us from seeing some of life’s most beautiful sights：stars，planets, and even galaxies(星系).”When I was a little boy , I loved the night sky,” recalls Robert Gent of the International Dark-Sky Association, an organization working to reduce light pollution.
“I remember looking up and the sky was full of stars ,and I asked , ‘How many are there? How far away are they? Can we visit them? ’ I became an astronomer because I was amazed by their beauty, ”he says .” Now in most big cities kids can’t see the stars like I did.”
Normally ，about2,500 stars can be seen by the human eyes without using any special equipment. But because of light pollution，today you actually see just 200 to 300 from suburbs, and fewer than 12 from cities.
Fortunately, there is a solution that is inexpensive and has benefits right away ， says Gent. “If we shine lights down at the ground instead of up into the sky ， and use lower brightness levels , we can save enormous amounts of energy and enjoy the beauty of the night skies.”
Many cities and towns have passed laws limiting lights at night ，making sure of enough shine for safety without creating a lot of light pollution.
Light pollution does harm to more than our view of the heavens. Research shows that lots of nighttime light can harm wildlife.
Migrating birds(候鳥)sometimes fly over cities and become confused by the brightness, flying in circles until they drop from extreme tiredness. Sea turtles need dark beaches for nesting and won’t nest near bright lights. Too much light at night may even affect human health, scientists are still learning more.
For all these reasons ，researchers are working on ways to use lights only when and where they are truly needed.
49．Today, people can't see the stars like before exactly they can see ______stars now.
A．a(chǎn)bout 2,500 B．just 200 C．less than 300 D．fewer than 12
50．We can infer from the passage that ________
A．light pollution has few bad effects on wildlife
B．too much lights will destroy sea turtle’s nests
C．kids now have less imagination towards the skies than their fathers.
D．shining the lights up into skies is a good way to solve the light pollution.
51．Which of the following statements is NOT mentioned in the passage?
A．Robert Gent showed great interest in the skies full of stars , which made him become an astronomer.
B．With more harm found in the future , there is still a long way fight against light pollution.
C．The International Dark-Sky Association is aimed at reducing light pollution.
D．Laws limiting lights at night have passed and saved light pollution successfully.

Do you find getting up in the morning so difficult that it’s painful? This might be called laziness, but Dr Kim has a new explanation . He has proved that everyone has a daily energy cycle.
During the hours when you labour through your work , you may say that you’re “hot.” That’s true . The time of day when you feel most energetic is when your cycle of body temperature is at its peak(高峰). For some people the peak comes during the forenoon. For other it comes in the afternoon or evening. No one has discovered why this is so , but it leads to such familiar words as :”Get up .John! You’ll be late for work again!” The possible explanation to the trouble is that John is at his temperature-and-energy peak in the evening. Much family quarreling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has.
You can’t change your energy cycle, but you can learn to make your life fit it better. Habit can help .Dr Kim believes. Maybe you’re sleepy in the evening but feel you must stay up late anyway . Counteract(對抗)your cycle to some extent by habitually staying up later than you want to . If your energy is low in the morning but you have an important job to do early in the day , rise before your usual hour . This won’t change your cycle , but you’ll get up steam and work better at your low point.
Get off to a slow start which saves your energy . Get up with a leisurely yawn(哈欠)and your body stretching. Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do usual work in the afternoon and save tasks requiring more energy or attention for your shaper hours.
56．If a person finds getting up early a problem, most probably _______
A．he is a lazy person B．he refuses to follow his own energy cycle
C．he is not sure when his energy is low D．he is at his peak in the afternoon or evening
57．Which of the follow may lead to family quarrels according to the passage?
A．Unknowing of energy cycle.
B．Understanding the energy cycle.
C．A change in a family member’s energy cycle.
D．Attempts to control the energy cycle of other family members.
58．If one wants to work more efficiently at his low point in the morning, he should ______
A．change his energy cycle B．overcome his laziness
C．get up earlier than usual D．go to bed earlier
59．You are advised to rise with a yawn and stretch because it will ___________
A．enable you to fix your attention on your work
B．help you to control your temper early in the day
C．keep your energy cycle under control all day
D．help to keep your energy for the day’s word
60．Which of the following statements is NOT TRUE?
A．getting off to work with a minimum effort helps people save their energy.
B．Dr Kim explains why people reach their peaks at different hours of day.
C．Habit can help people adapt to their own energy cycles.

生物：對激素?zé)狳c(diǎn)考題的歸納分析
對激素?zé)狳c(diǎn)考題的歸納分析
為了幫助廣大考生備考“激素分泌的調(diào)節(jié)和相關(guān)激素間的作用”這一考點(diǎn),筆者對各地的模擬試題及近年的相關(guān)高考題加以分析比較,從而歸納概括出以下三類題型的創(chuàng)新與預(yù)測。
[例題1]取正常小鼠，每天飼喂一定量的甲狀腺激素，3周后，該小鼠（ ）
A．新陳代謝增強(qiáng)，促甲狀腺激素含量增加
B．新陳代謝增強(qiáng)，促甲狀腺激素含量減少
C．新陳代謝減弱，促甲狀腺激素含量增加
D．新陳代謝減弱，促甲狀腺激素含量減少
[研析]本題考查的知識點(diǎn)是動物體內(nèi)甲狀腺激素的功能及其激素的反饋調(diào)節(jié)。動物體內(nèi)甲狀腺激素的主要功能是：促進(jìn)新陳代謝和生長發(fā)育，尤其對中樞神經(jīng)系統(tǒng)的發(fā)育和功能具有重要影響，提高神經(jīng)系統(tǒng)得興奮性。當(dāng)體內(nèi)血液中甲狀腺激素含量超過正常值時，通過反饋調(diào)節(jié)會抑制下丘腦和垂體的活動，垂體所分泌的促甲狀腺激素的含量則會減少。
[答案] B。
[點(diǎn)擊]對于甲狀腺激素和促甲狀腺激素之間的關(guān)聯(lián)是學(xué)生容易搞混的地方。學(xué)生應(yīng)該搞清楚，正常情況下，首先是促甲狀腺激素影響著甲狀腺激素的合成和分泌，其次，甲狀腺激素反過來又會影響促甲狀腺激素的合成和分泌。當(dāng)甲狀腺激素含量在血液中過高時，就是一個典型的反饋調(diào)節(jié)，促甲狀腺激素含量將會減少，從而會減少甲狀腺激素的合成和分泌，使甲狀腺激素含量在血液中趨于一個穩(wěn)定值。
[創(chuàng)新?預(yù)測1] 下圖表示甲狀腺活動調(diào)節(jié)的示意圖。對這一調(diào)節(jié)的描述錯誤的是（ ）
狳c(diǎn)考題的歸納分析.files/image002.jpg)
A．X與Y結(jié)構(gòu)分別表示下丘腦和垂體
B．a(chǎn)與b物質(zhì)分別表示促甲狀腺激素釋放激素和促甲狀腺激素
C．Z結(jié)構(gòu)的活動只受Y結(jié)構(gòu)的控制
D．血液中的甲狀腺激素含量起著反饋調(diào)節(jié)的作用
[答案] C 甲狀腺激素的分泌調(diào)節(jié)屬于反饋調(diào)節(jié)。當(dāng)寒冷等刺激影響下，下丘腦的一些細(xì)胞能合成并分泌促甲狀腺激素釋放激素，促進(jìn)垂體活動合成并分泌促甲狀腺激素，促甲狀腺激素又能刺激甲狀腺合成并分泌甲狀腺激素，從而促進(jìn)新陳代謝，以使機(jī)體抵御寒冷等刺激。但當(dāng)血液中甲狀腺激素的含量增加一定程度時，會抑制下丘腦和垂體的活動，使促甲狀腺激素釋放激素和促甲狀腺激素的合成和分泌減少，從而使血液中甲狀腺激素含量不致過高。本題就是對這一知識點(diǎn)的考查，因此A、B、D項(xiàng)屬于正確的。另外甲狀腺激素的分泌活動除了受垂體的調(diào)節(jié)外，還受血液中血糖濃度、其它激素和神經(jīng)系統(tǒng)的調(diào)節(jié)。
[例題2]下圖表示機(jī)體內(nèi)生命活動調(diào)節(jié)的途徑。下列說法錯誤的是（ ）
狳c(diǎn)考題的歸納分析.files/image004.jpg)
A．該圖示可以說明神經(jīng)系統(tǒng)可控制內(nèi)分泌系統(tǒng)的活動
B．胰島B細(xì)胞的分泌活動不受④過程的調(diào)節(jié)
C．如果感受器、①、下丘腦、⑦和內(nèi)分泌腺組成機(jī)體內(nèi)的某一反射活動的反射弧，則效應(yīng)器為圖中的的組織
D．如果圖示中的內(nèi)分泌腺為甲狀腺，則⑥的增加可引起③和④的減少
[研析]本題所示的是神經(jīng)調(diào)節(jié)和體液調(diào)節(jié)共同作用的圖，兩者之間，神經(jīng)調(diào)節(jié)為主，并控制著體液調(diào)節(jié)。胰島B細(xì)胞不受垂體控制，但受下丘腦的控制，圖中⑦就可作為這個實(shí)例。如果感受器、①、下丘腦、⑦和內(nèi)分泌腺組成機(jī)體內(nèi)的某一反射活動的反射弧，則效應(yīng)器為圖中的內(nèi)分泌腺，而不應(yīng)該是圖中的組織。甲狀腺激素的調(diào)節(jié)是一個反饋調(diào)節(jié)，當(dāng)其含量過高時，會減少促甲狀腺激素和促甲狀腺激素釋放激素的合成和分泌。
[答案] C。
[相關(guān)鏈接] 垂體、下丘腦在內(nèi)分泌活動中的重要作用:垂體是人體重要的內(nèi)分泌腺，它不僅本身能分泌多種激素，如生長激素直接調(diào)節(jié)控制生長發(fā)育、新陳代謝，而且能分泌幾種激素如促甲狀腺激素、促性腺激素，分別調(diào)節(jié)甲狀腺、性腺等內(nèi)分泌的活動。因此曾被稱為“內(nèi)分泌之王”。而垂體的活動又受下丘腦控制，下丘腦可以比喻為內(nèi)分泌的“王中王”，是機(jī)體調(diào)節(jié)內(nèi)分泌活動的總樞紐。它通過分泌促激素釋放激素來調(diào)節(jié)控制垂體的活動，如分泌促甲狀腺激素釋放激素促進(jìn)垂體合成分泌促甲狀腺激素，還能分泌促性腺激素釋放激素，促腎上腺激素釋放激素等。下丘腦是中樞神經(jīng)系統(tǒng)的一部分，本身能產(chǎn)生傳導(dǎo)興奮，其興奮性受大腦皮層控制，因此它是神經(jīng)調(diào)節(jié)和激素調(diào)節(jié)的聯(lián)系樞紐。
[創(chuàng)新?預(yù)測2] （多選題）下圖表示下丘腦神經(jīng)分泌細(xì)胞、垂體細(xì)胞、甲狀腺細(xì)胞及它們分泌的激素之間的關(guān)系。下列有關(guān)分析正確的有（ ）
狳c(diǎn)考題的歸納分析.files/image006.jpg)
A．激素A是促甲腺激素釋放激素
B．當(dāng)體內(nèi)缺乏I元素時，將導(dǎo)致激素C的合成受阻
C．人遭遇危險而情緒緊張時血液中激素C的含量將會增加
D． 激素C與下丘腦分泌的生長激素之間存在協(xié)同作用
[答案]ABC 激素C為甲狀腺激素，與生長激素之間有著協(xié)同作用。但生長激素是由垂體所分泌的，所以D選項(xiàng)錯誤。
[例題3]為探索影響動物體內(nèi)甲狀腺激素水平的相關(guān)因素，某研究性學(xué)習(xí)小組做了如下一些實(shí)驗(yàn)：
狳c(diǎn)考題的歸納分析.files/image008.jpg)
（l）實(shí)驗(yàn)一：取生長正常的成年雄鼠甲，對其體內(nèi)甲狀腺激素和促甲狀腺激素進(jìn)行不間斷檢測。每隔3d對甲鼠的甲狀腺做一次等量切除，其甲狀腺激素和促甲狀腺激素水平如上圖所示，請據(jù)圖回答：
①圖中曲線a表示的激素是 ，曲線b表示的激素是 。
②實(shí)驗(yàn)結(jié)果表明，在正常情況下，甲狀腺細(xì)胞的分泌功能（產(chǎn)生的激素量）與甲狀腺的體積成 關(guān)系。
③通過該實(shí)驗(yàn)，還可以給人啟示，對于患 的病人可以實(shí)施手術(shù)治療。
（2）實(shí)驗(yàn)二：取生長正常的成年雄鼠乙，每隔3d注射一次等量的促甲狀腺激素釋放激素，并測得其體內(nèi)甲狀腺激素和促甲狀腺激素含量的變化，總是先上升后下降，請分析產(chǎn)生這種生理變化的原因。
①當(dāng)體內(nèi)促甲狀腺激素釋放激素濃度升高時， 合成和分泌增多，進(jìn)而刺激甲狀腺合成和分泌甲狀腺激素。
②當(dāng)停止注射促甲狀腺激素釋放激素時，其體內(nèi)過高的 就會抑制 和 的分泌活動，從而使相應(yīng)的激素水平下降。
（3）為了驗(yàn)證碘是合成甲狀腺激素的原料，某同學(xué)提出了這樣一個實(shí)驗(yàn)方案：取生長狀況相同的雄鼠丙和雌鼠丁，其中給丙鼠每天喂含碘的食物，丁鼠每天喂不含碘的等量的食物；兩只鼠放在不同室內(nèi)條件下飼養(yǎng)，一段時間后對兩只鼠體內(nèi)甲狀腺激素水平進(jìn)行測定。請改正該方案中的不足之處： 。
[研析]本題結(jié)合實(shí)驗(yàn)全面考查了學(xué)生對甲狀腺激素和促甲狀腺激素之間關(guān)系的理解，以及考查了學(xué)生對實(shí)驗(yàn)基本操作規(guī)則的掌握程度。實(shí)驗(yàn)一中，由于切除甲狀腺，那么甲狀腺激素含量將會持續(xù)下降，促甲狀腺激素含量將會持續(xù)增加。通過該實(shí)驗(yàn)可用于治療甲亢病人的理論指導(dǎo)。實(shí)驗(yàn)二是探討甲狀腺激素的反饋調(diào)節(jié)。下丘腦分泌的促甲狀腺激素釋放激素，垂體分泌的促甲狀腺激素會促進(jìn)甲狀腺激素的合成和分泌，同時甲狀腺激素反過來又會影響下丘腦和垂體的活動。在實(shí)驗(yàn)設(shè)計方案中，該同學(xué)忽略了等量原則：實(shí)驗(yàn)用的老鼠性別應(yīng)相同，培養(yǎng)的條件也應(yīng)該相同，且有利于老鼠的生存。
[答案]（1）①促甲狀腺激素 甲狀腺激素 ②正相關(guān) ③甲亢
（2）①促甲狀腺激素 ②甲狀腺激素 下丘腦 垂體
（3）①丙鼠和丁鼠的性別應(yīng)相同 ②放在相同的適宜條件下飼養(yǎng)
[方法/技巧]1．配合題意，理解圖的含義，理解圖在解題中所起的重要作用。
2．緊扣圖所給的信息回答題目，盡量不要偏離圖形所反應(yīng)出的知識點(diǎn)。
3．學(xué)科內(nèi)知識會靈活應(yīng)用，能觸類旁通。
4．掌握必須的實(shí)驗(yàn)設(shè)計原則：等量原則、單一變量原則。
[創(chuàng)新?預(yù)測3] 下面是采用動物實(shí)驗(yàn)法和臨床觀察法，研究甲狀腺的內(nèi)分泌功能。分析結(jié)果，回答下列問題：
實(shí)驗(yàn)一：腺體制劑飼喂蝌蚪，結(jié)果蝌蚪發(fā)育加快，體型小。
實(shí)驗(yàn)二：摘除成年狗腺體，結(jié)果成年狗食欲不振、臃腫、呆笨、萎靡。
實(shí)驗(yàn)三：摘除小狗腺體，結(jié)果除上述癥狀外，發(fā)育停止。
臨床四：地方性甲狀腺腫癥狀是腺體腫大，勞動時心跳快、氣短，以食鹽加碘可以防治。
