Last month, my family experienced a terrible thing.My brother Tom had just received a new train set. We decided to build a little “world” for it with mountains, streetlights and even a lake. We found a large board that was big enough to hold the train. We spent over a week building the things with paper and cardboard.When we finished all the things, we showed everyone our new train set. It was very wonderful. Now, it was time to turn it on. I flipped the switch and the train began to move. Everyone was excited.I turned to look at Tom, and he looked strange. He was shaking. “Tom!” I shouted. He didn’t move, looking straight ahead. Suddenly, my dad realized what was happening. He reached quickly for the switch and turned off the train.The water had leaked(漏) from the bag under the board and arrived where Tom was standing. One of our wires had fallen under the table and was touching it. We sent Tom to the hospital. And luckily Tom was fine. He told us that when the electricity was on, he could not move at all.We learned a lesson that day. Keep water away from electricity! It’s too dangerous.26．How long did it take them to build the little “world”?A．A month        B．Over a month.      C．More than a week.   D．Less than a week.27．The underlined word “flipped” in Paragraph 3 most probably means “________”.A．起飛            B．按下（開關(guān)）      C．計(jì)時(shí)           D．發(fā)電28．The underlined word “it” in Paragraph 5 refers to ________A．the board        B．the water         C．the bag          D．the table29．Which of the following is TRUE according to the passage?A．After finishing the train set, my dad turned it on.B．There were mountains, bridges and a lake on the large board.C．Tom couldn’t move at all when the electricity was on.D．I found Tom was strange and then I turned off the switch quickly.30．According to the passage, we should remember to ________A．stay away from water             B．have something electric near usC．take good care of the young         D．keep water away from electricityBCars make our lives more convenient. But they can also be a problem, especially fossil fuel (化石燃料) cars, which are a major cause of air pollution.   To improve the environment, many countries are developing electric vehicles (EVs, 電動(dòng)車). Among them, China is taking a leading role and has created the world’s largest EV market, according to the Wall Street Journal.   Last year, over 40 percent of the 753,000 EVs sold worldwide were sold in China, more than twice as many as the number sold in the United States, according to the International Energy Agency.   Chinese drivers are already big fans of EVs. Chinese auto companies, including BYD and BAIC (北汽集團(tuán)), rank among the top in the world in EV sales.   “Charging (充電) an electric car is cheaper than filling up a fossil fuel car with gas,” said Wu Hao, who bought an electric car from BAIC this year.    However, there are still some problems. It can be hard to find charging stations (充電樁) and the cars can’t go far before needing to be recharged.   Some of these problems are being solved. In 2014, China had 31,000 charging stations, according to Xinhua. Now China has the world’s largest EV charging network, with more than 167,000 charging stations in total, according to the Economic Daily.  Developing EVs is one of many efforts China has made to reduce pressure on its environment after the government promised to stop increases in carbon dioxide emissions (二氧化碳排放量) by 2030. “As China goes, so will the world’s auto industry,” the Wall Street Journal said.31. What do we know about electric vehicles?  A. They are sold more than fossil fuel cars.  B. They are more convenient than fossil fuel cars.  C. They cause less pollution than fossil fuel cars.  D. They are safer than fossil fuel cars.32. How many EVs were sold in China last year?  A. More than 301,000.  B. More than 753,000.  C. More than 31,000.  D. more than 450,800.33. What do we know about charging EVs?  A. It is convenient to charge EVs.  B. People need to charge them near their home.  C. It costs less money than filling up a fossil fuel car.  D. Charging EVs takes too much time.34. What do we know from the story?  A. EVs can go far after they are charged.  B. More countries will encourage people to use EVs.  C. Fossil fuel cars will disappear in the future.  D. China should build a larger EV charging network.35. The passage is mainly aboutA. how to deal with air pollutionB. why EVs are so popularC. the development of EVs in ChinaD. why China needs electric cars CUntil the late 1800s, most people went to bed soon after sunset. They used candles and oil for light. Amer­ican inventor Thomas Edison changed the way people lived when he invented the first light club .The light bulb was just one of the more than 1000 inventions of this great inventor.Thomas Alva Edison was born in 1847.

In order to thank him, the father taught Edison how to operate the telegraph. Edison then made improvements to the telegraph. He earned money from his inventions.In 1876 , Edison started the first research laboratory in New Jersey. He worked very hard. He lived in his laboratory and became rich because of his inventions. He married twice and had six children. But he worked so hard that he spent little time with his families.Edison's greatest inventions included an improved telephone, photograph and electric battery. He is best remembered for inventing the long-lasting light bulb.In the 1870s. many inventors were trying to make a light bulb. Edison tried hundreds of times, Finally he found a filament（燈絲） made of carbon. Edison's lamp was a great success. It burned for more than 40 hours.36.

We use energy every day.Electricity is a form of energy and this is what powers the TV, hairdryer, phone, fridge, electric toothbrush and more! Our growing need for energy is one of the problems facing the world today, because producing electricity also produces pollution.Here are some simple ways to make a big difference when using electricity.On or off? Leaving televisions and computers on with the little red light showing still uses electricity, even though they might look like they’re turned off. To stop this you can turn them off.Lights out! Turning lights off when you’re not in the room can save a lot of energy.Fridge door closed. The fridge is an important part of the kitchen, because it keeps food fresh, cool and healthy! But it takes a lot of energy to keep cool, so try not to leave the fridge door open or put hot things inside.Use the sun's energy. An increasing number of people are fitting solar panels（太陽能電池板） to their houses. They create electricity from sun-light, which can then be used to power our homes. Solar heating panels make hot water, reducing the need for electricity or gas.41．The underlined word “powers” means “     ” in Chinese.A．動(dòng)力 B．權(quán)利 C．驅(qū)動(dòng) D．散發(fā)42．What can save energy according to the passage?A．Turn the lights off when you’re not in the room.B．Use gas to create electricity.C．Leave the fridge door open or put hot things inside.D．Leave televisions and computers on.43．There are        ways to save electricity in the passage.A．three B．four C．five D．six44．Which is NOT true according to the passage?A．We don't have any energy problem today.B．The fridge can keep food fresh, cool and healthy.C．When we produce electricity, we produce pollution, too.D．Electricity from sunlight can be used to power our homes.45．The passage mainly tells us      .A．electricity is a form of energyB．how to create electricity from sunlightC．how to use the fridge correctlyD．the different ways to save electricity 第二節(jié) 閱讀填空（共5小題；每小題1分，滿分5分）根據(jù)短文內(nèi)容，將下面A---E五個(gè)句子分別填入文中空缺處，使得補(bǔ)全后的短文意思通順，結(jié)構(gòu)完整。Electricity is an important part in our life.
