陕西省榆林市绥德中学2019-2020学年高一上学期第三次阶段性考试试卷第Ⅰ卷（选择题，共48分）一、选择题。
（第1～9题为单项选择题，第10～12题为多项选择题，每小题4分，选对但选不全得2分，共48分）1.对下列现象解释正确的是A. 在一定拉力作用下，车沿水平方向前进，所以力是物体运动的原因B. 向上抛出的物体由于惯性向上运动，以后惯性变小，速度越来越小C. 质量大的物体运动状态不容易改变是由于物体的质量大，惯性也就大的缘故D. 高速行驶的汽车由于速度大，所以惯性大，很难停下来【答案】C【解析】【详解】A．力不是使物体运动的原因，物体不受力时也可以做匀速直线运动，故A错误；B．向上抛出的物体由于惯性向上运动，以后由于受到重力的作用，速度越来越小，物体的惯性只与质量有关，质量不变，惯性不变，故B错误；CD．惯性大小的量度是质量，惯性越大，运动状态越难改变，与速度大小无关，故C正确，D错误；故选C。
2.如图所示，当小车水平向右加速运动时，物块M相对车厢静止与其后竖直壁上，当车的加速度a增大时A. 物块仍相对车厢滑动B. 物块所受静摩擦力增大C. 车厢壁对物块的压力增大D. 车厢对物块的作用力方向不变【答案】C【解析】【详解】以物块为研究对象，物体受重力Mg，车厢的弹力N和静摩擦力f，根据牛顿第二定律可得，水平方向：N=Ma，竖直方向：f=MgC．当加速度增大时，车厢壁对物块的压力N增大，故C正确；AB．当加速度增大时，物块仍相对于车厢静止，在竖直方向受力平衡，即f=Mg不变；故AB均错误；D．物体受车厢的弹力和向上的静摩擦力，当加速度增大时，N增大，静摩擦力f不变，则两者合力的方向变化，车厢对物块的作用力方向改变，故D错误。
故选C。
3.如图所示，用力F推放在光滑水平面上的物体P、Q、R，使其做匀加速运动. 若P和Q之间的相互作用力为6 N，Q和R之间的相互作用力为4 N，Q的质量是2 kg，那么R的质量是（）A. 2 kgB. 3 kgC. 4 kgD. 5 kg【答案】C【解析】【详解】对Q受力分析有：6N-4N=2kg×a，则运动的加速度为1m/s2，再对R受力分析得：m R a=4N，得m R=4kg，选项C正确．4.如图所示，小张同学左手抓起一只篮球，当篮球与手臂都静止时，下列说法正确的是（）A. 手对篮球的作用力的大小等于篮球的重力B. 手对篮球的作用力的大小大于篮球的重力C. 手对篮球的作用力和篮球的重力是一对相互作用力D. 手对篮球的作用力和篮球对手的作用力是一对平衡力【答案】A【解析】【详解】AB．篮球受到重力和手对篮球的作用力，在这两个力的作用下处于平衡状态，故手对篮球的作用力和篮球的重力是一对平衡力，等大反向。

I have been very naughty and the school master is very angry with me. She is going to write to you. You must come and take me away from here. She does not want me in the school any longer. The trouble started last night when I was smoking a cigarette in bed. As I was smoking, I heard footsteps coming towards the room .I did not want a teacher to catch me smoking, so I threw the cigarette away. Unfortunately, the cigarette fell into the waste--paper basket. It caught fire.There was a curtain near the waste --paper basket. It caught fire too. Soon thewhole room was burning. The master phoned the fire brigade. The school is a long way from the town and before the fire brigade arrived, the whole school was on fire.

Not all people realize this, but it is quite true. The human body can live without food for a long time, but two or three days without water usually result in death.Many people do not understand how much water the human body needs, butmany people do not drink enough, especially in the hot weather. Most people drink when they are thirsty but often need more water after exercises.65 to 70 percent of the human body is water. Water is important in several different ways. Most people need five to seven litres(升) of water every day, but we need not drink this amount because a lot comes from the food we have. If we don’t have enough water, however, we will feel tired and many become ill. Do you know what the best drink is? Yes, you are right. Cold water!8.Do most people drink five litres of water every day?_______A. Yes, because water is the most importantB. No, because what we eat contains waterC. Yes, because we can’t live without waterD. No, because we are not thirsty9.How much water are there in the human body?_________A. About three fourths of the human body is water.B.

Cold water is the best drink.B. Few people understand how much water the human body needs.C. Not all the people realize water is the most important.D. When we feel tired or become ill, we never need any water.DIf you want to be a volunteer, you have to answer the following typical questions. Do you want to work with people, animals or machines? Do you want to work indoorsor outdoors, directly serve people in need or serve people behind the scenes? Every year, thousands of people in the west offer volunteer service. V olunteering greatly strengthens the community because it helps the old, the young, the weak, the sick, and the disabled and the injured to solve problems.V olunteers usually help in many different ways. They may give people advice, offer friendship to the young, drive the elderly to church (if up to the driving age), advise kids against drugs, work as assistants in schools or nursing homes, raise funds, plant trees, help out in local libraries and do many other things. V olunteering can be a few hours a week or a few hours a month. Anybody who wants to serve people in need can become a volunteer.In fact, the art of volunteering is a process of both giving and receiving. V olunteering allows volunteers to meet new people, make new friends and mix with people from all walks of life. V olunteering is an excellent way to experiment and try out new techniques and skills, discover your individual talents and explore career choice.

operations．“She can’t run but she can walk really fast，but there are iust certain things she wishes she could do,” said Stella’s mother，Kim Malpass．One of those things is goingto the restroom on her own．“This is the one thing in school she needs help with,” Kim said，“she can do just about everything on her own but she just isn’t able to pull her pants(裤子) up.’’Jodi Carroll，Stella’s doc tor for two years had been trying to find a solution，but had no luck reaching out to clothing companies．“After man y searches I realized we needed to invent something，” Carroll said．She then got in touch with the Petoskey High School drafting team，and no doubt they were all in．“As soon as I told the students about it, they supported（支持）me and we went to work right away,” Lauren Liebler，the school’s engineering teacher, says．Students say it was the perfect project for the students，combining brainstorming，design thinking，problem-solving and tests．Once Stella tried the device(装置)，it was kind of a disappointment to find out that the first one didn’t work，but then it was just the matter of coming up with the next idea or seeing how they could improve the first one to make it work．After three

hotels in Paris than any other city in France, as this is such a popular place for a short weekend break．But for a break with a difference，how about staying in one of the chateaux(城堡)that have been changed into famous hotels in luxury（奢侈、奢华）?On the other hand，if you enjoy taking a touring holiday，there are thousands of French campsites（营地）in France，where you can put up your own tent，but on many campsites for more convenience you could even live in a chalet(棚屋)．You can easily find campsites with excellent facilities（设施）that include swimming pools，shops，clubs，bars，entertainment，playgrounds，etc．These are good for the whole family holiday and some even offer other activities such as tennis，fishing，swimming and more，which can make for an

car．Before they left，they asked me for advice about how to find accommodation（膳宿、住处）．I suggested that they should stay at“bed and breakfast” houses，because this kind of accommodation gives a foreign visitor a good chance to speak English with the family．My friends listened to my advice，but they came back with some funny stories．“We didn’t stay at bed and breakfast houses，”they said，“because we found that most families were away on holiday.’’I thought this was strange．Finally I understood what had happened．My friends spoke little English，and they thought“V ACANCIES”meant“holidays”，because the Spanish word for “holidays” is “vacations”．So they did not go to house where the sign outside said“V ACANCIES”，which in English means there are free rooms．Thenmy friends went to house where the sign said “NO V ACANCIES”，because they thought this meant the people who owned the house were not away on holiday．But they found that these houses were all full．As a result，they stayed at hotels!We laughed about this and about mistakes my friends made in reading other signs．In Spanish，the word “DIVERSION”means fun．In EngIish，it means that workmen are repairing the road，and that you must take a different road．When my friends saw t he wo rd‘DIVERSION’on a road sign，they thought they were going to have fun．Instead，the road ended in a large hole．English people have problems too when they learn foreign languages．Once in Paris，when someone offered me some more coffee，I said“Thank you”in Frenc h．I meant that I would like some more．However，to my surprise，the coffee pot was taken away! L ater I found out that “Thank you”in French means“No，thank you．”12.My Spanish friends wanted advice about____________．A．learning English B．finding places to stay in England C．driving their car on English roads D．going to England by car13.I suggested that they stay at“bed and breakfast”houses because_______．A．they would be able to practice their EnglishB．it would be much cheaper than staying in hotelsC．it would be convenient for them to have dinnerD．there would be no problem about finding accommodation there14.“NO V ACANCIES”in English means________．A．no free rooms B．free roomsC．not away on holiday D．holidays15.If you see a road sign that says“DIVERSION”in UK，you will___________．A．fall into a holeB．have a lot of fun and enjoy yourselfC．find that the road is blocked by crowds of peopleD．have to take a different road第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填人空白处的最佳选项。
