Period Two Learning about Language Ⅰ.閱讀理解
A
Every child should have a solid science education whether they want to be the next Albert Einstein or Michael Jordan.Science is all around us;it is everywhere,reaching everything that we do.The “we” in that last statement includes children.Children that understand how science plays a role in our everyday lives have a wonderful foundation(基礎(chǔ))for success in life.Children can learn science at any age.The earlier they start the better.The best way for kids to learn is through play and repetition.These are wonderful science toys for preschool science activities.With play being the best way kids learn,it only makes sense then introducing toys to them that encourage understanding science.Children love to use their imagination to have fun and to help them understand the world around them.So play is a wonderful time to introduce science to them.Think of the games that we used to play.Don’t Spill the Beans, Don’t Break the Ice,the Telephone Game,Lincoln Logs,each of these games has science behind it.Children are by nature curious(好奇的)as they feel out the world,trying to make sense of what is around them.Science feeds that curiosity hunger that they have.It is a hunger that needs to be encouraged and satisfied.Finding these toys is not as hard as one would think.To make sure that you get good quality toys,visit science toy shops online.These are the best places to find unique(獨(dú)特的)science toys such as 3D space projectors,or Hydro Greenhouses.Help your children appreciate the world around them with understanding the world around them.This way,they understand how we are all connected together.Children will not only question the world,but be able to come up with answers to those questions on their own.Science is life.【語(yǔ)篇解讀】 不管將來(lái)是否從事科學(xué)研究,每一個(gè)孩子都需要接受科學(xué)教育,不僅因?yàn)榭茖W(xué)和我們的日常生活密切相關(guān),而且學(xué)習(xí)科學(xué)會(huì)為他們未來(lái)的成功奠定基礎(chǔ)。1.Don’t Spill the Beans,Don’t Break the Ice,the Telephone Game and Lincoln Logs are the games ________.
A.that are the most widely played B.that can introduce science to children C.that most students like to play at school D.that keep children strong and healthy 答案 B 細(xì)節(jié)理解題。根據(jù)第二段最后的“Think of the games that we used to play.Don’t Spill the Beans,Don’t Break the Ice,the Telephone Game,Lincoln Logs,each of these games has science behind it.”可知,這些游戲都有科學(xué)的成分,能教給孩子們科學(xué)知識(shí)。] 2.The third paragraph is mainly to tell us that ________.
A.children are born curious about the world B.it is necessary to feed children in time C.science toys can satisfy children’s curiosity
D.most of the toys online are very cheap 答案 C 主旨大意題。通讀本段可知,本段主要講孩子天生對(duì)這個(gè)世界好奇,而科學(xué)可以滿足他們的好奇心,而教給他們科學(xué)知識(shí)的最好方法是讓他們玩科學(xué)玩具,故選C項(xiàng)。] 3.The text is most probably written for ________.
A.parents
B.scientists
C.children
D.teachers 答案 A 推理判斷題。該文講述了孩子接受科學(xué)教育的重要性以及最佳方式,由最后一段“Help your children appreciate the world around them...”可知,本文的寫作對(duì)象最有可能是家長(zhǎng)。]

Wong Fuk-wing,a Hong Kong volunteer(志愿者)at an orphanage(孤兒院)in Yushu,was killed in the earthquake when he was trying to save others on April 14,2010.Wong managed to run safely out of the building with some children when the first quake happened at 7:50 am on April 14,but he went back inside to rescue three other children and three teachers inside,although he knew the danger of aftershocks(余震). At 10 am,all the children and one of the teachers were saved.However,Wong was buried under the fallen building and died.The other two teachers were still waiting to be rescued.46-year-old Wong was a truck driver,who often said he could only give his efforts to charity(慈善)instead of money,as he did not earn a lot.His tragic(悲劇的)end touched the hearts of many people both in Hong Kong and on the mainland.Wong began volunteering in 2002.In 2003,Wong was told by the doctor he got serious illness,which gave him a great blow.However,the illness did not deter the warm-h(huán)earted man.When the earthquake struck Wenchuan in Sichuan Province in 2008,Wong rushed to the disaster area of Shifang to offer his help though his family did not want him to go.In fact,Qinghai is a place Wong had often visited since 2006.As a volunteer,he gave out medicine and clothing to the orphanage there.No one could expect that Wong would die helping others.Hong Kong Chief Secretary Henry Tang Ying-yen said he had “the highest respect” for the hero who gave his life for others.“What he did has shown the Hong Kong spirit.” The citizens of Hong Kong called him “the pride of Hong Kong’s people” and people on the mainland have also praised him as “a true hero”. 【語(yǔ)篇解讀】 本文介紹了香港義工黃福榮——阿福的故事。4.Wong died in the earthquake ________.
A.a(chǎn)fter he sent medicine and clothing to the orphanage B.when he returned to save the teachers and students C.because he suffered from his serious illness again D.a(chǎn)s the first earthquake happened 答案 B 細(xì)節(jié)理解題。本文第二、三段介紹了阿福地震中救人犧牲的事跡,故選B項(xiàng)。] 5.The underlined word “deter” in Para.5 refers to “________”.
A.prevent C.beat
B.refuse D.encourage 答案 A 詞義猜測(cè)題。由第五段中的“When the earthquake struck Wenchuan in Sichuan Province in 2008,Wong rushed to the disaster area of Shifang to offer his help...”可以看出嚴(yán)重的疾病也未能阻止他去汶川地震災(zāi)區(qū)當(dāng)一名志愿者。] 6.Which of the following words can be used to describe Wong according to the passage? A.Honest and self-satisfactory B.Warm-hearted and selfless.C.Proud and self-centered.D.Capable and hardworking.答案 B 推理判斷題。阿福從2002年開(kāi)始做義工,不顧自身疾病參與汶川地震和玉樹(shù)地震的援救工作,并在玉樹(shù)地震中獻(xiàn)出生命。從他的事跡不難看出,阿福是一個(gè)熱心而無(wú)私的人。]

A 13-year-old American boy on Saturday became the youngest climber to conquer Mount Qomolangma,the world’s highest mountain.Jordan Romero from Big Bear,California,climbed up the 8,850 meter summit(峰頂)from the Tibetan side.On the same day,a Nepali(尼泊爾的)man,Apa Sherpa,broke his own world record of climbing Qomolangma when he reached the summit for the twentieth time.Apa Sherpa’s team set off from Nepal’s capital,Kathmandu,last month,heading for the base camp(大本營(yíng))on the Chinese side of the mountain.“The team has just called in and believe that they are standing on top of Mt.Qomolangma,”Romero’s blog said.“Their dreams have now come true.Everyone is happy.”
The climbing has put Romero one step closer to reaching his goal of climbing the highest mountains on all seven continents(大洲).“It is just a goal,”Romero said.He had already climbed five peaks(高峰),and needs to climb only Vinson Massif,the highest peak in Antarctica,to hit his goal.The youngest person before to climb Qomolangma was 16-year-old Temba Tsheri Sherpa of Nepal.Romero climbed together with a team including his father Paul and three local guides.He wanted to pick a small piece of rock from the top of the world and wear it in a necklace.While Nepal insists that anyone planning to climb Mount Qomolangma must be 16,China does not have any age restrictions(限制).Some mountain climbers haven’t agreed with the Romero family for letting him try it but his father said the climbing from the Chinese side is less dangerous.【語(yǔ)篇解讀】 本文是一篇新聞。一名13歲的美國(guó)男孩成功登上了珠穆朗瑪峰的峰頂,轟動(dòng)了世界。
7.Jordan Romero climbed up Mount Qomolangma mainly to ________.
A.meet Apa Sherpa B.build his body C.break the world record D.realize part of his goal 答案 D 細(xì)節(jié)理解題。根據(jù)第四段的“The climbing...reaching his goal of climbing the highest mountains on all seven continents(大洲).”可知,喬丹攀登珠穆朗瑪峰的主要目的是要實(shí)現(xiàn)他的夢(mèng)想——登上世界七大洲的高峰。] 8.Why did Jordan Romero choose to climb from the Chinese side of Mount Qomolangma? A.China allows climbers of any age to climb Mt.Qomolangma.B.It wasn’t far from Jordan’s base camp on the Chinese side.C.There were more challenges on the Chinese side.D.There were more local guides on the Chinese side.答案 A 細(xì)節(jié)理解題。根據(jù)最后一段可知,從珠峰的中國(guó)境內(nèi)攀爬有兩個(gè)原因,一是沒(méi)有最小年齡限制,二是危險(xiǎn)較小(他的父親這樣認(rèn)為)。故選A項(xiàng)。] 9.Which of the following is TRUE? A.Apa Sherpa climbed up Mount Qomolangma from the Tibetan side to the base camp on the Nepali side.B.Jordan Romero’s father and three American guides climbed up Mount Qomolangma with Romero.C.The youngest person who has climbed up the world’s highest mountain is 16 years old.D.Apa Sherpa has reached the summit of Mount Qomolangma twenty times.答案 D 細(xì)節(jié)理解題。由第二段最后一句可知A項(xiàng)錯(cuò)誤;由第五段第二句可知B項(xiàng)錯(cuò)誤;由第一段第一句話可知C項(xiàng)錯(cuò)誤;由第二段第二句可知D項(xiàng)正確。]
10.What would be the best title for the passage? A.The great dream of picking rocks from top of Qomolangma B.California teen becomes the youngest to climb Qomolangma C.The most number of successful Qomolangma climbs D.Mount Qomolangma climbing becomes more popular 答案 B 主旨大意題。本文是一篇新聞,報(bào)道了一名13歲的美國(guó)男孩登上了珠穆朗瑪峰頂,成為世界上最年輕的成功登頂珠峰的人。故B項(xiàng)最能概括本文大意。] Ⅱ.根據(jù)短文內(nèi)容,從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。
__1__ Safety in the highway is not totally out of our hands.Here are four ways we can protect ourselves when we travel.__2__ People in small cars are injured more often and more severely than people traveling in large cars.Factories of small cars are strengthening their products’ safety,which helps.But the mix of large cars and small cars on the road is the main reason of the problem.Being thrown into glass and metal car parts,or being thrown from the car can really hurt or even kill you.__3__ The safety belt’s main purpose is to pull you back if your car has a sudden crash with another vehicle or object,or if it rolls over.A belt can reduce the chance of deadly injury by 45% and the chance of serious injury by 50%.Air bags are important.More than half of all new cars sold have air bags.Air bags provide protection in frontal crashes—the type of crash that kills the most drivers—when they are also wearing safety belts.Most people are demanding air bags in the cars they buy.__4__ Effective as they are,they can’t take the place of safety belts.Drunk driving crashes are less likely to happen if you don’t drink.__5__ Many people have realized that drunk driving can lead to death and injury,prison time and other results.There are movements to strengthen penalties(處罰)for drinking and driving.A.How to drive safe.B.You are safe in a large car.C.How to protect ourselves in the highway? D.Air bags are not installed in all cars.E.That’s why safety belts should be worn.F.Drunk driving is the most serious problem.G.But the protection provided by air bags is limited in side or rear crashes.答案 1.C 2.B 3.E 4.G 5.F

2.引入新課:
通過(guò)上節(jié)課的學(xué)習(xí),我們已知道:物體運(yùn)動(dòng)狀態(tài)改變時(shí)產(chǎn)生加速度,而產(chǎn)生的加速度又和物體的質(zhì)量及所受力的大小有關(guān),那么:加速度跟物體所受力的大小及物體質(zhì)量之間有什么關(guān)系呢?本節(jié)課我們就來(lái)研究這個(gè)問(wèn)題。
二、新課教學(xué)
(一)用投影片出示本節(jié)課的學(xué)習(xí)目標(biāo):
1.理解加速度與力的關(guān)系;
2.理解加速度與質(zhì)量的關(guān)系
3.理解牛頓第二定律的內(nèi)容。
(二)學(xué)習(xí)目標(biāo)完成過(guò)程:
1、加速度和力的關(guān)系:
(1)用投影片出示本節(jié)課所用的實(shí)驗(yàn)裝置,教師進(jìn)行講解:圖中是兩輛質(zhì)量相同的小車,放在光滑的水平板上,小車的前端各系上細(xì)繩,繩的另一端跨過(guò)定滑輪各掛一個(gè)小盤,盤里放有數(shù)量不等的砝碼,使兩輛小車在不同的拉力下做勻加速運(yùn)動(dòng)。
(2)對(duì)本次實(shí)驗(yàn)中說(shuō)明的兩個(gè)問(wèn)題
a:砝碼跟小車相比質(zhì)量較小,細(xì)繩對(duì)小車的拉力近似地等于砝碼所受的重力。
b:用一只夾子夾住兩根細(xì)繩,以同時(shí)控控制兩輛小車。
(3)實(shí)驗(yàn)的做法:
a:在兩砝碼盤中放不同數(shù)量的砝碼,以使兩小車所受的拉力不同。
高考資源網(wǎng) 2006精品資料系列
b:打開(kāi)夾子,讓兩輛小車同時(shí)從靜止開(kāi)始運(yùn)動(dòng),一段時(shí)間后關(guān)上夾子,讓它們同時(shí)停下來(lái)。
(4)需觀察的現(xiàn)象,觀察兩輛車在相等的時(shí)間里,所發(fā)生的位移的大小。(實(shí)驗(yàn)現(xiàn)象:所受拉力大的那輛小車,位移大)
(5)分析推理:
a:由公式s1?at2得到在時(shí)間t一定時(shí),位移s和加速度a成正比;
2b:由實(shí)驗(yàn)現(xiàn)象得到:小車的位移與他們所受的拉力成正比。
c:推理得到結(jié)論:對(duì)質(zhì)量相同的物體,物體的加速度跟作用在物體上的力成正比,即:
a1F1?或a?F a2F2a1F1?a2F2
(6)鞏固練習(xí):
a.據(jù)得到:要使物體在短時(shí)間內(nèi)速度的改變很大,即加速度很大,就必須給物體提供。
b.競(jìng)賽用的小汽車,要求起動(dòng)后幾秒鐘內(nèi)速度由零達(dá)到60m/s以上,他們?yōu)槭裁匆b備功率很大的發(fā)動(dòng)機(jī)?
2:加速度和質(zhì)量的關(guān)系:
(1)實(shí)驗(yàn)裝置同上;
(2)說(shuō)明與前次實(shí)驗(yàn)的不同。
前一次實(shí)驗(yàn)中,我們是保持小車質(zhì)量不變,而改變小車所受力的大小,來(lái)研究加速度和力之間的關(guān)系的。
本次實(shí)驗(yàn)是使兩輛小車所受拉力相同,而在一輛小車上加放砝碼的,以增大質(zhì)量,研究加速度和質(zhì)量之間關(guān)系的。
(3)實(shí)驗(yàn)現(xiàn)象:
在相同的時(shí)間里,質(zhì)量小的那輛小車的位移大。
(4)分析推理,得到結(jié)論:
在相同的力作用下,物體的加速度跟物體的質(zhì)量成反比,即
a1/a2=m2/m1或a∝m3:牛頓第二運(yùn)動(dòng)定律
(1)綜合上述實(shí)驗(yàn)中得到的兩個(gè)關(guān)系,得到下述結(jié)論:
物體的加速度跟作用力成正比,跟物體的質(zhì)量成反比,且加速度的方向跟引起這個(gè)加速度的力的方向相同。
(2)公式表示:
a∝F或者F∝ma m即:F=kma
a:如果每個(gè)物理量都采用國(guó)際單位,k=1;
高考資源網(wǎng) 2006精品資料系列
b:力的單位(牛頓)的定義:使質(zhì)量為1千克的物體產(chǎn)生1m/s2的加速度的力叫做1牛頓。
(3)推廣:上面我們研究的是物體受到一個(gè)力作用的情況,當(dāng)物體受到幾個(gè)力作用時(shí),上述關(guān)系可推廣為:
物體的加速度跟所受的合力成正比,跟物體的質(zhì)量成反比,加速度的放心跟合力的方向相同。即F合=ma。
(4)介紹F合和a的瞬時(shí)對(duì)應(yīng)關(guān)系
a:只有物體受到力的作用,物體才具有加速度。
b:力恒定不變,加速度也恒定不變。
c:力隨著時(shí)間改變,加速度也隨著時(shí)間改變。
d:力停止作用,加速度也隨即消失。
4:例題分析(課本例題)
(1)學(xué)生閱讀例題內(nèi)容
(2)分析:
??質(zhì)量m已知???必須先求F1和F2的合力,而合力的大小可
要求物體的加速度?以用作圖法求解,也可以用計(jì)算法求解。
(3)用投影片展示解題過(guò)程:
如圖所示,建立平面直角坐標(biāo)系,把力F1和F2分別沿x軸和y軸的方向分解F1的兩個(gè)分力為:
F1x?F1xcos60o,F2y?F2sin60o
F2的兩個(gè)分力為:F2xo?F2cos60o,F2y?F2sin60
F1y和F2y大小相等,方向相反,相互抵消,F(xiàn)1x和F2x的方向相同,所以:
F合?F1x?F2x?F1cos60o?F2cos60o?5N?5N?10N
已知合力F合和質(zhì)量m,據(jù)F合=ma,即可求得:
10Na?F合??5m/s2
2kg
三:小結(jié)
1:本節(jié)課的研究方法——控制變量法
2:牛頓第二運(yùn)動(dòng)定律確定了a和F之間的大小關(guān)系,也確定的a和F的方向關(guān)系
3:求解合力時(shí),可采用建立平面直角坐標(biāo)系,將各個(gè)力沿x軸和y軸分解,最后求合力的方法。
