They are both places with very cold temperatures and few people live there. However, the North and South Poles are not much alike as people may imagine.The North Pole has no land, only thick ice. Temperatures seldom go above 32℉, at which water turns into ice. Most of the time, it stays below zero. In winter temperatures are usually as low as -30℉.Although conditions were very poor, people tried for many centuries to reach the North Pole. About 100 years ago, two men, Robert Peary and Mathew Henson, were able to get to this environment full of troubles and difficulties. They reached the North Pole on March 8th, 1909.It was really a hard trip for them.There are few things more dangerous than crossing the Arctic (北极圈) on foot. People who stayed there may face many problems: very cold temperatures, sudden storms, and even hunger. Most of the area is uninhabited. Few people can live in such a difficult place.People might think that with such low temperatures for most of the year, the ice would be thick and hard. However, this is not true in the Arctic. The movement of the ocean water under the ice may often cause many different changes on the surface. Sometimes the ice breaks into two opening lanes of water (水道) called "leads". Anyone who falls into a lead can be frozen to death in a few minutes.1. This passage is probably from .A. a book reviewB. a science bookC. a school reportD. a computer magazine2.According to the passage, what happened about 100 years ago?A. Two men succeeded in getting to the North Pole.B. Temperatures in the North Pole went above 32℉.C. The environment in the North Pole suddenly became worse.D. The North Pole changed into thick ice because of the temperatures.3. What does the underlined word "uninhabited" probably mean in Chinese?A.气候恶劣的B.充满危险的C.困难重重的D.无人居住的4.The reason for the ice to break into two opening lanes of water is .A. that the temperature suddenly dropsB. that the water under the ice is frozenC. that the ocean water under the ice movesD. that the surface is covered with lots of ice5.What does this passage mainly talk about?A. The thick ice in the North Pole.B.A difficult trip to the North Pole.C. The real situation in the North Pole.D. The differences between the North Pole and the South Pole.BMick Polly, an owner of a toy store, lives with his teenage daughter Carolina in Kentucky.

She was sitting high with her eyes closed, her skin still wet from the shower and her messy hair behind her back. I realized she was taking in every touch from my hands. Today we would send Kitty away for a week of a summer camp. This was all my idea. She's nearly 12, and I notice that I'm with my child nearly 24 hours a day. Living on the farm without neighbours, Kitty has become increasingly dependent(依赖的) on me.After lunch, we drove to the camp place. After we got out of the car, we were introduced to the other children. Kitty followed me closely, holding my hand all the time. “I need youfor a few more minutes,”she said to me, horror in her eyes.I pulled away and walked up to a camp worker. “Excuse me,”I said loudly,“I'd like to introduce you to my daughter. Maybe you could help her meet afew of these kids.”He came over to talk to Kitty and I kissed on her face.

As a conservative (保守的〕country, India does not welcome 58________expression of affection(感情〕such as hugging and kiss. 59________Indian people’s eyes are big and considered the most beautiful in Asia, it is not proper to look straight into a person’s eyes while talking. Indian people make less eye communication than Western people do . However, this doesn’t 60________that Indian people are not honest. It is just part of their culture.

Eat Eastern foodD. See forests.BThe main difference between China and Western countries on the dinner table is chopsticks instead of a knife and fork, but that’s just a small difference. Besides, in decent(合宜的) restaurants, you can always ask for a pair of knife and fork, if you find the chopsticks not helpful enough.The real difference is that in the West, you have your own plate of food, while in China the dishes are placed on the table and everyone shares. If you are being treated to a formal〔正式的〕dinner and particularly if the host thinks you’re in the country for the first time, he will do his best to give you a taste of many different types of dishes. The meal usually begins with a set of at least four cold dishes, to be followed by the main courses of hot meat and vegetable dishes. Soup will then be served ( unless it is a Guangdong-style restaurant), followed by rice, noodles or dumplings. Perhaps one of the things that surprise a Western visitor most is that some of the Chinese hosts like to put food into the plates of their guests. In formal dinners, there are always “ public〞--chopsticks and spoons for this purpose, but some hosts may use their own chopsticks. This is a sign of real friendship and politeness. It is always polite to eat the food, If you do not eat it, just leave the food on the plate.People in China tend to over-order food, for they will find it embarrassing (为难〕if all the food is consumed.( 吃光);When you have had enough , just say so, Or you will always overeat!〔〕71. What’s the real difference between Chinese and Western table manners ?A. The tools people use to eat.B. If people share food on the same plate.C. The things people like to eat.D. How to begin the dinner politely. ( )72. If a foreigner first comes to have dinner in a Chinese family, he may be ____A. given little foodB. served with rice firstC. served with many dishesD.asked to use “public〞chopsticks ( )73. Which of the following is the right order for most Chinese formal dinners according to the passage ?A. Rice-----Soup-----hot meat----cold dishesB. Vegetable-----dishes-----soup-----dumplings----cold dishesC. Cold dishes-----hot meat-----soup----riceD. Cold dishes-----suop----hot meat---rice( )74. What can we infer from the passage ?A. In the West it’s common to put food into the plates of their guests.B. Westerners think it’s polite to eat up all the food on the plate.C. It’s not polite to leave the food on the plate in China.D. Most Westerners are richer than Chinese people.( )75. What’s the best title for this passage ?A. Having Dinner with Foreigners.B. How to use Chopsticks.C.The Importance of Table Manners.D. Different Table Manners.CA greeting is a way of saying “ Hello “ to someone. People in different countries greet each other in different ways. 76_______________ In the United States , people usually shake hands. The handshake has an interesting origin(起源)77______.Shaking the person’s right hand while looking him or her in the eye is the usual way. Handshakes are also common in other parts of the world, including Britain and Russia. In Russia , a man often holds another man’s hand very strongly during the handshake. Most people in New Zealand also greet each other by shaking hands 78_______.In other countries, such as France and Belgium, hugging and kissing are more common when two people meet. In those culture , people kiss each other on the cheek. 79_____In Saudi Arabia , men might hug and kiss each other ( but not with a woman ) on the check.

For example, people drove on the left side of the road and many people carried an umbrella all the time. There were also many other things that I found really ▲ .The first thing I noticed was how polite British people were. When I got on the bus, the driver would greet me; when people got off the bus, they would say “Thank you” to the driver; when I went into a shop, I would be greeted by a smili ng salesman who would say, “Can I help you?”The family I stayed with were very nice, but their house was full of oddities (怪现象). Firstly, there were carpets (地毯) everywhere, even in the bathroom. Also, the bathroom was full of surprises. The first time I tried to wash my hands I burned myself. The cold and hot water came out of different taps (水龙头)! Then, when I tried to dry my hair I couldn't find a socket (插座) for my hairdryer. Maybe that wasn't such a big surprise. More surprising was the fact that British people didn't take their shoes off when they went into a house — can you imagine?I guess that for British people all of these things are normal. It's only when you visit a foreign country that you realize that what you think is normal is not. Normality depends on where you are.根据材料内容选择最佳答案。

(1)为了通过测量得到如图所示I U关系的完整曲线,在下图中甲和乙两个电路中应选择的是图。

简要说明理由:(电源电动势为9V,内阻不计,滑线变阻器的阻值为0~100Ω)。

(2)在图丙电路中,电源电压恒为9V,电流表读数为70mA,定值电阻R1=250Ω。

由热敏电阻的I U关系曲线可知,热敏电阻两端的电压为V;电阻R2的阻值为Ω。

(3)举出一个可以应用热敏电阻的例子:三、计算题(共2个小题,共40分)10.(20分)一个直流电动机的内电阻r=2Ω,与R=8Ω的电阻串联接在线圈上,如图所示。

已知线圈面积为2m2,共100匝,线圈的电阻为2Ω,20T的匀强磁场中绕OO'以转速n=600r/min匀速转动,在合线圈在B=2π上开关S后电动机正常工作时,电压表的示数为100V,求电动机正常工作时的输出功率。

11.(20分)一个小型水力发电站,发电机输出电压U0=250V,内电阻可以忽略不计,最大输出功率为P m=30kW,它通过总电阻R线=2.0Ω的输电线直接向远处的居民区供电。

设居民区所有用电器都是额定电压U 用=220V的电灯,总功率为P用=22 kW,不计灯丝电阻随温度的变化。

(1)当居民区的电灯全部使用时,电灯两端的电压是多少伏?发电机实际输出的电功率是多大?(2)若采用高压输电,在发电机端用升压变压器,在用户端用降压变压器,且不计变压器和用户线路的损耗。

已知用户变压器的降压比为40∶1,当全部用户电灯正常发光时,输电线上损耗的功率是多大?##参考答案1.C 解析:电流方向随时间周期性变化的电流为交变电流,电流方向不改变的为直流电,显然两图中表示的都是交变电流,A错误;两图中V=220V,图乙电压的最大值相同,但图甲中是正弦交流电,有效值为2是锯齿形交流电,有效值不能按上式计算,B错误;图甲所示的正弦式交=100 π,所以电压的瞬时值表达式流电的周期为2×10-2s,角速度ω=2πT为u=311sin100πt V,C正确;变压器原副线圈的电压与匝数成正比,频率不变,D错误。

2.AC 解析:电容器是通高频、阻低频,选项A正确;电感线圈是通低频、阻高频,选项C正确。

3.D 解析:A选项,由图象可知电动势的有效值为220V,而电压表测量的是路端电压,其大小为U=ER+r R=22095+5×95V=209V;B选项,由图象读出交变电流的周期为T=0.02s,则频率f=1T=50Hz,一个周期内电流的方向要改变2次,故每秒钟电流方向要改变2×50=100(次);C选项,灯泡的实际功率为P=(ER+r )2R=(22095+5)2×95W=459.8W;D选项,由焦耳定律得Q=(ER+r )2rt=(22095+5)2×5×1J=24.2J。

本题正确选项为D。

4.A 解析:输出电压U1不是输电线上损耗的电压,故不能用U12R计算导线上损耗的功率,A错;导线损耗电压为ΔU=U1-U2,故P损=ΔU 2R =(U1-U2)2R,B正确;P损=I2R=ΔUI=(U1-U2)I,故C、D项正确。

5.B 解析:由图象可以看出随着浓度的增大电导均匀增大,则电阻均匀减小,电路中电流非均匀增大,电压表示数也将非均匀增大,所以选项B正确。

6.BCD 解析:闭合电路中感应电动势的瞬时值表达式e=U m sinωt=nBSωsin ωt=12nBl2ωsin ωt,A错;在t=π2ω时刻,线圈转过90°,线圈平面与磁场平行,B正确;电阻R上产生的热量为Q=(m2R+r)2Rt=n2B2l4πωR16(R+r)2,故C正确;从t=0时刻到t=π2ω时刻,通过R的电荷量q=it=nΔΦΔtR+r Δt=nΔΦR+r=nB×l×12lR+r=nB l22(R+r),故D正确。

7.AB 解析:由T2的副线圈两端电压的表达式知,副线圈两端的电压有效值为220V,电流为I=22011A=20A,A对;由于输电线电流I'=204A=5A,所以升压变压器的输入功率为P=P线+P R=52×10W+202×11W=4650W,B对;发电机中的电流变化频率与T2的副线圈两端电压的频率相同,也为50Hz,C错;当用电器的电阻R0减小时,其消耗的功率变大,发电机的输出功率变大,D错。

8.D 解析:由图象知T=0.02s,ω=2πT=100πrad/s,u=202sin(100πt)V,A项错误;由于副线圈两端电压不变,故只断开S2,两灯串联,电压为额定值一半,不能正常发光,B项错误;只断开S2,副线圈电路电阻变为原来2倍,由P=U 2R知副线圈消耗功率减小,则原线圈输入功率也减小,C项错误;输入电压额定值U1=20V,由U1U2=n1 n2及P R=U22R得P R=0.8W,D项正确。

9.答案:(1)甲电压可从0调到所需电压,调节范围较大(2)5.2 111.8(111.6~112.0均可)(3)热敏温度计(提出其他实例,只要合理均可)解析:由于图中要求测量多组数据,所需电压调节范围较大,且从零开始变化,所以应选用分压电路,即图甲;根据欧姆定律可以先求出R1的电流I1=36mA,所以热敏电阻和R2电流为I2=I-I1=34mA,由图可读出热敏电阻在34mA时的电压为5.2V,则R2两端电压为3.8V,即可求出R2=111.8Ω。

10.答案:800W解析:线圈转动时产生的电动势的最大值为:E m =NBSω=200 2V 有效值为:E=m 2=200 V设线圈的电阻为r',则电路中的电流I 为:I=E -U R +r '=10A电动机正常工作时的输出功率为: P=UI-I 2r=800W 。

11.答案:(1)131V 14.9kW (2)12.5W 解析:(1)如图所示由P 用=U 用2R用得,R 用=U 用2P用=2.2ΩI=U 0R 用+R线=25042A=59.5 AU 灯=IR 用=131VP 输=IU 0=14880W=14.9kW 。

(2)若采用高压输电,在发电机端用升压变压器,在用户端用降压变压器,如图所示P 用=U 4I 4,因U 4=220V,P 用=22kW 所以,I 4=100AI3 I4=n4 n3,I3=140I4=2.5AP损=I32R线=12.5W。
