It happened last weekend, when 18yearold Evoni Williams was serving an elderly man breakfast. He needed help. So Williams leaned over the table with a fork and a knife and cut up his ham for him. It might have ended there, but a customer named Laura Wolf was struck enough to take a picture and post it online. “I didn't know the photo was taken until a couple of hours later，” Williams told the Houston Chronicle. “When I saw it, it's just something I would do for anybody. I was so busy in here, and I actually took the time to stop and hear what he had to say instead of walking past him.” It apparently meant something to others too. As of Sunday, more than 130,000 people had reacted to the post and nearly 7,000 have shared it.But the story has extended beyond the Internet. Williams, a recent Texas City High School graduate, was honored at a

While most people were warming up their cars， Trevor， my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually does。
After putting in 10 hours of labor, he returned to find his bike gone。
The bike， a black Kona 18 speed， was our only transport。
Trevor used it to get to work， putting in 60-hour weeks to support his young family。
And the bike was also used to get groceries（食品杂货），saving us from having to walk long distances from where we live。
I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story。
Shortly after that， several people in our area offered to help. One wonderful stranger even bought a bike, and then called my husband to pick it up. Once again my husband had a way to get to and from his job。

河北省沧州市盐山中学2019-2020学年高二下学期4月月考英语试卷一、阅读理解(共两节，满分40分）第一节（共15小题，每小题2分，满分30分）AIt was a winter morning, just a couple of weeks before Christmas 2005. While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone.The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries(食品杂货),saving us from having to walk long distances from where we live.I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, and then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity as a whole. And it has influenced us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.1.Why was the bike so important to the couple?A.The man’s job was bike racing.B.It was their only possession.C.It was a nice Kona 18 speed.D.They used it for work and daily life.2.We can infer from the text that ________.A.the couple worked 60 hours a weekB.people were busy before ChristmasC.the stranger brought over the bikeD.life was hard for the young family3.What do the couple learn from their experience?A.Strangers are usually of little help.B.One should take care of their bike.C.News reports make people famous.D.An act of kindness can mean a lot.BI travel a lot,and I find out different “styles” (风格)of directions every time I ask “How can I get to the post office?”Foreign tourists are often confused(困惑的)in Japan because most streets there don’t have names;in Japan,people use landmarks(地标)in their directions instead of street names. For example, the Japanese will say to travelers,“Go straight down to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop. ”In the countryside of the American Midwest, there are not usually many landmarks. There are no mountains, so the land is very flat; in many places there are no towns or buildings within miles. Instead of landmarks, people will tell you directions and distances. In Kansas or Iowa, for example, people will say, "Go north two miles. Turn east,and then go another mile."People in Los Angeles, California, have no idea of distance on the map; they measure distance in time,not miles. “How far away is the post office?” you ask. “Oh,”they answer, “it’s about five minutes from here. ’’You say,“Yes,but how many miles away is it?”They don’t know.It’s true that a person doesn’t know the answer to your question sometimes. What happens in such a situation? A New Yorker might say,wSorry, I have no idea. But in Yucatan, Mexico, no one answers “I don't know." People in Yucatan believe that “I don't know" is impolite. They usually give an answer, oftena wrong one. A tourist can get very, very lost in Yucatan!4.When a tourist asks the Japanese the way to acertain place,they usually .A.describe the place carefullyB.show him a map of the placeC.tell him the names of the streetsD.refer to recognizable buildings and places5.Which is the place where people measure distance in time?A.New York.B.Los Angeles.C.Kansas.D.Iowa.6.People in Yucatan may give a tourist a wrong answer_____.A.in order to save timeB.as a testC.so as to be politeD.for fun7.what can we infer from the text?A.It's important for travelers to understand cultural differences.B.It's useful for travelers to know how to ask the way properly.C.People have similar understandings of politeness.D.New Yorkers are generally friendly to visitors.CSports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.There are many environment-friendly sport. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes;and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.8.Which of the following is the author most probably in favor of?A.Playing basketball in a gymB.Motor racing in the desert.C.Cycling around a lake.D.Swimming in a sports center.9.What do we know about golf from the passage?A.It is popular in Portugal and Spain.B.It needs water and electricity to keep its courses green.C.It pollutes the earth with chemicals and wastes.D.It causes water shortages around the world.10.The author uses power walking as an example mainly because ___________.A.it uses fewer resourcesB.it improves our healthC.it is an outdoor sportD.it is recommended by experts11.The author writes the passage to ____________.A.show us the function of major sportsB.encourage us to go in for green sportsC.discuss the major influence of popular sportsD.introduce different types of environment-friendly sportsDGoing green seems to be a fad(时尚) for a lot of people these days. Whether that is good or bad, we can't really say, but for the two of us, going green is not a fad but a lifestyle.On April 22, 2011, we decided to go green every single day for an entire year. This meant doing 365 different green things, and it also meant challenging ourselves to go green beyond easy things. Rather than recycle and reduce our energy, we had to think of 365 different green things to do and this was no easy task.With the idea of going green every single day for a year, Our Green Year started. My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all the green things that could be done to help the environment. We wanted to push the message that every little thing counts.Over the course of Our Green Year, we completely changed our lifestyle. We now shop at organic(有机的) stores. We consume less meat, choosing green food. We have greatly reduced our buying we don't need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made fresh bread. In our home office anyone caught doing something un-green might be punished.Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planet.12.What might be the best title for the passage?A.Keeping Open-MindedB.Protecting the PlanetC.Going GreenD.Celebrating Our Green Year13.It was difficult for the couple to live a green life for the whole year because _____________.A.they were expected to follow the green fad.B.they didn't know how to educate other people.C.they needed to perform unusual green tasks.D.They were unwilling to reduce their energy.14.What did the couple do over the course of Our Green Year?A.They sold their home-made food.B.They ignore others' un-green behavior.C.They chose better chemical cleaners.D.They tried to get out of their un-green habits.15.What can we infer from the last paragraph?A.The government will give support to the green project.B.Some people disagree with the couple's green ideas.C.The couple may continue their project in the future.D.Our Green Year is becoming a national campaign.第二节，七选五（共5小题，每小题2分，共10分）根据短文内容,从短文后的七个选项中选出能填入空白处的最佳选项。

河北省沧州市盐山中学2019_2020学年高二化学上学期期末考试试题(B)(含解析)
河北省沧州市盐山中学2019-2020学年高二化学上学期期末考试试题（B ）（含解析）一、单选题（本大题共20小题，共40.0分） 1.下列说法或表示方法正确的是( )A. 等质量的硫蒸气和硫固体分别完全燃烧，后者放出的热量多B. 氢气的燃烧热为285.8 kJ·mol －1，则氢气燃烧的热化学方程式为2H 2(g)＋O 2(g)=2H 2O(l) ΔH＝－285.8 kJ·mol －1C. Ba(OH)2·8H 2O(s)＋2NH 4Cl(s)= BaCl 2(s)＋2NH 3(g)＋10H 2O(l) ΔH<0D. 已知中和热为57.3 kJ·mol －1，若将含0.5 mol H 2SO 4的浓溶液与含1 mol NaOH 的 稀溶液混合，则放出的热量大于57.3 kJ 【答案】C 【解析】【详解】A.硫蒸汽所含能量比硫固体高，所以，等物质的量的硫蒸汽和硫固体分别完全燃烧，前者放出热量多，选项A 错误；B ．氢气的燃烧热为285.8kJ•mol -1，氢气的燃烧热热化学方程式为：H 2（g ）+12O 2（g ）=H 2O （l ）△H=-285.8 kJ/mol ，选项B 错误；C ．反应中固体生成气体，△S ＞0，在常温下能自发进行，△G=△H-T•△S ＜0，故ΔH<0，选项C 正确；D ．已知中和热为57.3kJ•mol -1，若将含0.5molH 2SO 4的浓硫酸溶液与含1mol NaOH 的溶液混合，由于浓硫酸溶解会放出热量，所以放出的热量要大于57.3kJ ，选项D 错误； 答案选C 。
2.将等物质的量的A 、B 混合于2L 的密闭容器中，发生下列反应：3A （g ）+B （g ）⇌xC （g ）+2D （g ），经2min 后测得D 的浓度为0.5mol/L ，c （A ）：c （B ）=3：5，以C 表示的平均速率v （C ）=0.25mol •L -1•min -1，下列说法正确的是（ ） A. 反应速率()v B 0.25= 11mol L min --⋅⋅ B. 该反应方程式中，x 1= C. 2min 时，A 的物质的量为1.5mol D. 2min 时，A 的转化率为60%【答案】C 【解析】【详解】A 、根据题意得v （D ）=0.5mol/L ÷2min=0.25 mol ·L -1·min -1，则根据化学反应速率之比等于方程式中化学计量数之比可知v （B ）=1/2v （D ）=0.125 mol ·L -1·min -1，A 错误； B 、根据题意得v （D ）=0.5mol/L ÷2min=0.25 mol ·L -1·min -1，以C 表示的平均速率v （C ）=0.25mol ·L -1·min -1，根据化学反应速率之比等于方程式中化学计量数之比可知x ＝2，B 错误；C 、2min 时，D 的物质的量是0.5mol/L ×2 L=1mol ，所以消耗A 、B 的物质的量分别是1.5mol 、0.5mol ，设A 、B 起始物质的量均为y ，则剩余A 、B 的物质的量分别是y-1.5mol 、y-0.5mol ，根据c(A)：c(B)=3：5，解得（y-1.5mol ）/(y-0.5mol)=3:5，解得y=3mol 。

Appreciation.BGuangzhououtbreak linked to strains inIndiaThe gene sequencing of the COVID-19 outbreak inGuangzhou.Guangdongprovince, indicates it is very similar in structure to the mutatedstrains detected inIndia, a senior health official from the city said on Sunday.“And it has the characteristic of quick spread.” Chen Bin, deputy director of the city's health commission, said at a news conference inGuangzhouon Sunday.She urged relevant departments and medical staff to act quickly to block the chain of infection and control the spread of the coronavirus in the southern metropolis.Zhang Zhoubin, deputy director of theGuangzhoucenter for disease control and prevention, said the strain of coronavirus spreads easily.“The virus can be spread through a meal or through a short period of indirect contact,” he said.The city reported five confirmed eases and 21 asymptomatic carriers as of 2 pm Sunday after the first con finned case was detected in the city's Liwan district on May 21, Chen said.To prevent the virus from spreading, the city government tightened its disease control and prevention measures over the weekend. Six communities and housing estates previously designated as low-risk areas were raised to medium-risk ones, Chen said.In addition to asking local residents to get vaccinated, the city has organized nucleic acid testing in Haizhu and Yuexiu districts starting from Sunday. Residents in specific areas of Tianhe, Baiyun and Panyu districts have also been required to take nucleic acid tests to expand the screening of suspected patients and asymptomatic carriers.Liwan previously required all its residents to take nucleic acid tests.As of Saturday, more than 2-25 million residents of the city have had samples collected for nucleic acid tests, Chen said. More than 10,000 medical workers from the entire city have been sent to Liwan to help vaccinate locals against COVID-19 and collect samples for nucleic acid testing.Deng Wenjun, director of circulation section with Guangzhou Supply and Marketing Cooperative, said there are sufficient supplies of food and daily necessities in the medium-risk areas.4. What is the characteristic of the COVID-19 which broke out inGuangzhou?A. It disappears quickly.B. It spreads fast.C. It has a lot to do with temperature.D. It has the same nature as the seasonal flu.5. Which district have residents who have not been required to take nucleic acid tests?A. Tianhe.B. Haizhu.C. Panyu.D. Zengcheng.6. Which of the following statements is TRUE?A. The virus can hardly be spread through a short period of indirect contact.B. There are 21 symptomatic carriers in the Liwan district as of 2 pm Sunday.C. All the people living in Liwan district arc previously asked to take nucleic acid tests.D. Supplies of food and daily necessities in the medium-risk areas arc still not enough.7. Where can you probably find this article?A. On a news website.B. In a fashion magazine.C. In a history book.D. In a travel journal.CIf you believe in thermometers (温度计), you should believe in global warming. And if you believe in eating French fries with your hamburger, you should worry more about carbonemission.It won't happen overnight, but as the planet’s climate changes, the growth cycles of main crops will all be heavily affected. Here are three of the crops that might not beat the heat.The potato actually needs a great deal of beauty rest to develop properly. “They need a cool nighttime temperature in order to start growing the tuber, the part that we eat,” Nelson says.Temperature and altitude are two primary concerns in coffee growth, and farmers are stuck between a rock and a hard place. “We know that coffee grows in a certain temperature range,” Nelson says. “They've been moving up the mountains, but at some point you run out of mountains to move up.” Higher-grade strains of Arabica coffee in Central American regions are at particular risk due to the need for lower growing temperature, especially since diseases and pests are also becoming more of a factor as temperatures rise.Even if you're looking at the direct effects of temperature alone, rice is in trouble. “As nighttime temperatures go up, the rice is going to have a problem flowering and won't make as many seeds,” Nelson says. In addition to this direct heat consequence, rising sea levels will flood many rice paddies and destroy water salinity levels, while droughts will lower production, raise prices, and further shame westerners who are clumsy with chopsticks to be able to clear their plates once a new grain is adopted.8. What is the closest meaning to the underlined word “emission” in Paragraph 1?A. Mixture.B. Pollution.C. Giving off.D. Going down.9. What does the potatoes' development need according to Nelson?A. Cool temperature at night.B. Sudden rise of the temperature.C. Enough water and salt.D. Much sunshine and fresh air.10. The rice is difficult to flower,probably because ________.A. sea levels go up suddenlyB. many seeds can't be producedC. the temperature rises at nightD. both temperature and altitude rise11. What is the best title for the text?A. How Does Global Warming Affect WesternersB. How Does the Cool Temperature Affect RiceC. What Is the Real Reason For Crops’ GrowthD. Three Crops That Won't Survive Climate ChangesDHow much do consumers care about the carbon footprint of the products they buy? Would they care more if the goods were labeled with emissions（排放物）data?Does it matter at which stage in the lifecycle of a product the carbon is emitted? Research published in the International Journal of Environmental Policy and Decision Making offers a way to find out．Study participants view a carbon footprint label as similar to labels that have appeared on some existing products．The label shows the carbon dioxide emissions connected with their production, transportation, usage and disposal（清理）, thus showing the buyer the likely effect on climate change of buying a particular product．In the first group of studies, the research team proved that carbon emissions and a carbon emissions label would indeed play a role in consumer product decisions, although not as great a role as price．In a second set of studies, the team found that emissions connected with usage were most important to consumers followed by the transportation and disposal stages．The carbon footprint of the producing process was considered less important to consumers than the other stages in the product's lifecycle because it is outside the consumer's control．That is, the participants felt they were less responsible for carbon emitted during producing process．Consumers value recycling a product, but the researchers found that, overall, the consumers would preferproducers to offset（补偿）carbon emissions rather than having toaddressthe problem directly themselves．Consumers are increasingly concerned with climate change problems, and already carbon labeling isappearing on some products．"We find that participantsnot only take the carbon label into account when making product decisions, but they want detailed information on the label," the researchers explain．They suggest that companies should prepare for how carbon emissions labels might affect future consumer choice．12. Which of the following most affects consumer's choice?A. Labels．B. Price．C Packaging． D. Carbon footprint．13. About the carbon dioxide emissions in the product's lifecycle, which stage do consumers care most?A. Usage stage．B. Transportation stage．C. Disposal stage．D. Producing stage．14. Which of the following can best replace the underlined word "address"?A. Look into．B. Point out．C. Deal with．D. Run into．15. What can be inferred from the last paragraph?A. Companies should take carbonemissions more seriously．B. All products have been labeled with carbon emissions data．C. Producers will attach less importance to carbon emissions labels．D. Products labeled with carbon emissions data will have poor sales．第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
