【解析】本文记述了一位母亲对孩子的正确教育：从小培养独立做事的好品格。
6.句意：当我有困难的事要做时，我常常向妈妈求助。
ask动词原形；asking动名词；to ask动词不定式；asked过去式。这里是：used to do sth.意为“过去常常做某事”，需用动词不定式。故选C。
7.句意：但她总是说：“亲爱的，你自己做吧。”
Do动词原形；Does第三人称单数；Did过去式；To do动词不定式。分析句子结构可知，这里是肯定祈使句，用动词原形。故选A。
8.句意：我认为她是世界上最懒的妈妈！
from从……起；at在；on在……上；in在(某范围或空间内的)某一点。由后面的提示词the world可知，这里是短语in the world意为“在世界上”。故选D。
9.句意：例如，有一天，我决定邀请几个朋友来我家。
few几乎没有，修饰可数名词；a few一些，修饰可数名词；little几乎没有，修饰不可数名词；a little一些，修饰不可数名词。few，little表示“几乎没有”，其意义是否定的；a few，a little表示“有一些”，其意义是肯定的。由空后的friends可知，这里是可数名词复数，表示肯定意义，因此用a few修饰。故选B。
10.句意：对不起，我在弹吉他。我没有时间。
play动词原形；played过去式；plays第三人称单数；am playing现在进行时。结合语境分析，这里应该用现在进行时，表示动作的正在进行，其结构是be+动词的现在分词。故选D。
11.句意：亲爱的，恐怕我帮不了你。
can’t不能；mustn’t禁止；needn’t不必；shouldn’t不应该。根据“I don’t have time.”可知，这里应该是我不能帮助你。故选A。
12.句意：因为我妈妈很懒，我不得不洗衣服和打扫房间。
If如果；When什么时候；Because因为；Before之前。分析句子结构可知，这里是由because引导的原因状语从句。故选C。
13.句意：我甚至不得不自己去看牙医。
I我，主格代词；me我，宾格代词；my我的，形容词性的物主代词；myself我自己，反身代词。前文说妈妈太“懒”了，什么都不帮我做，因此这里是说看牙医是我自己去的，因此用反身代词。故选D。
14.句意：我真的很难把每件事都做好，但我学到了很多。
and和；but但是；or或；so所以。分析句子结构可知，前后句之间是转折关系，因此用but连接。故选B。
15.句意：多棒的母亲啊！
What感叹句引导词，后跟名词；What a后跟可数名词单数；How感叹句引导词，后跟形容词或副词；How a没有这种形式。这题考查感叹句，此题的中心词mother是名词，因此感叹词用what引导，而mother又是单数，因此用冠词a修饰，符合：What + a/an＋形容词＋可数名词单数＋主语＋谓语！故选B。

Energy is everywhere. 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（太阳能电池板） 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.
26. The underlined word “powers” means “ ” in Chinese.

【答案】CABAD
【解析】本文叙述了电是我们的必需品，我们离不了电，但是我们今天仍然面临着能源问题，因此我们要节约用电，短文给出了四条节约用电的建议。
26. 词义猜测题。根据the TV, hairdryer, phone, fridge, electric toothbrush and more后面的这些词都是名词，所以划线的应该是动词。理解上下文可知句意：电是一种能源，可以使电视、吹风机、手机、冰箱、电动牙刷以及更多的东西运转。因此power的意思是"使……运转"，驱动。根据Electricity is a form of energy可以推测这里划线的是“驱动”。故选C。
27. 细节理解题。根据Turning lights off when you’re not in the room can save a lot of energy.可知，当不在房间里的时候请把灯关掉，这样省电，故选A。

Cars 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, 电动车). 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 (北汽集团), rank among the top in the world in EV sales.
“Charging (充电) 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 (充电桩) 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.

Wind power is a very clean source of energy. This is how wind power works. Wind makes windmills spin (旋转). When the windmills spin, they make electricity. Then we can use the electricity. A lot of people think that wind power is new, but that’s not true. For thousands of years, people have used wind to sail boats and move water. We still do those things today, but these days we mostly use wind power to make electricity.
Wind power is a very popular source of energy (能源). Most people think that we should use it more and more. First of all, it’s clean. Windmills don’t pollute the environment at all. Second, we can use wind power forever. After all, we will always have wind. Also, wind power is cheap, and it’s getting even cheaper.
A lot of people don’t understand wind power very well. They believe that there are problems with wind power, but many of those problems are not real. For example, some people say that windmills are dangerous for birds. They used to be true, but it isn’t true anymore. Old windmills killed birds because they spun very fast. New windmills spin slowly, and they aren’t dangerous for birds.
However, there are real problems with windmills. One problem is that many people think windmills are very ugly. This is a problem for people, because windmills are often in very pretty areas. Also, wind doesn’t blow all the time, so we can’t use wind power all the time. Finally, windmills are noisy. Wind power is becoming more and more common. Right now, more than 80 countries use wind power. About 2. 5 percent of the world’s power comes from the wind. For some countries, that number is a lot higher. Wind power gives Denmark more than 25 percent of its electricity.
36. When did people start using wind power
A. About 25 years ago. B. About 80 years ago.
C. About 500 years ago. D. Over 1,000 years ago.
37. New windmills don’t kill birds because ________.
A. birds don’t fly near them B. they spin slowly
C. they are shorter than old windmills D. new windmills don’t spin
38 . ________, so we CAN’T use wind power all the time.
A. Windmills break all the time B. We can’t use windmills at night
C. Windmills are too expensive to use all the time D. Wind doesn’t blow all the time
39. What does the article say about wind power
A. Most people don’t like it. B. It’s getting cheaper.
C. Denmark doesn’t use it. D. There are no problems about it.
40. What is the best title for the passage
A. Expensive Windmills B. Cheap and Clean Energy
C. Popular and Clean Wind Power D. Dangerous Birds

Energy is everywhere. 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（太阳能电池板） 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.

Cars 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, 电动车). 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 (北汽集团), rank among the top in the world in EV sales.
“Charging (充电) 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 (充电桩) 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.

Wind power is a very clean source of energy. This is how wind power works. Wind makes windmills spin (旋转). When the windmills spin, they make electricity. Then we can use the electricity. A lot of people think that wind power is new, but that’s not true. For thousands of years, people have used wind to sail boats and move water. We still do those things today, but these days we mostly use wind power to make electricity.
Wind power is a very popular source of energy (能源). Most people think that we should use it more and more. First of all, it’s clean. Windmills don’t pollute the environment at all. Second, we can use wind power forever. After all, we will always have wind. Also, wind power is cheap, and it’s getting even cheaper.
A lot of people don’t understand wind power very well. They believe that there are problems with wind power, but many of those problems are not real. For example, some people say that windmills are dangerous for birds. They used to be true, but it isn’t true anymore. Old windmills killed birds because they spun very fast. New windmills spin slowly, and they aren’t dangerous for birds.
However, there are real problems with windmills. One problem is that many people think windmills are very ugly. This is a problem for people, because windmills are often in very pretty areas. Also, wind doesn’t blow all the time, so we can’t use wind power all the time. Finally, windmills are noisy. Wind power is becoming more and more common. Right now, more than 80 countries use wind power. About 2. 5 percent of the world’s power comes from the wind. For some countries, that number is a lot higher. Wind power gives Denmark more than 25 percent of its electricity.
36. When did people start using wind power
A. About 25 years ago. B. About 80 years ago.
C. About 500 years ago. D. Over 1,000 years ago.
37. New windmills don’t kill birds because ________.
A. birds don’t fly near them B. they spin slowly
C. they are shorter than old windmills D. new windmills don’t spin
38 . ________, so we CAN’T use wind power all the time.
A. Windmills break all the time B. We can’t use windmills at night
C. Windmills are too expensive to use all the time D. Wind doesn’t blow all the time
39. What does the article say about wind power
A. Most people don’t like it. B. It’s getting cheaper.
C. Denmark doesn’t use it. D. There are no problems about it.
40. What is the best title for the passage
A. Expensive Windmills B. Cheap and Clean Energy
C. Popular and Clean Wind Power D. Dangerous Birds
D
