New Energy Vehicles: Driving
Towards a Greener Future
In recent years, new energy vehicles(NEVs), especially electric cars(EVs, 电车), have become a hot topic worldwide.As countries want to reduce air pollution and control climate change, NEVs are seen as a key way.China, for example, has taken a leading role in this field, creating the world's largest EV market.In 2024, 40% of the 753，000 EVs sold worldwide were sold in China, far more than other countries.
NEVs are environmentally friendly.Unlike traditional fossil fuel cars(油车), which emit harmful gases, EVs produce zero tailpipe pollution.Charging(充电) an EV is also cheaper than fueling a gasoline car.As Wu Hao, an EV owner in China, said “Charging costs much less than buying gas.” Additionally, governments encourage people to buy NEVs.
However, there were some challenges.A few years ago, finding charging stations was difficult, and EVs couldn't travel long distances.But progress has been made.China built over 167，000 charging stations, forming the world's largest EV charging network.Battery technology is also improved, allowing newer models to drive farther on a single charge.Many believe autonomous driving and advanced battery systems are making NEVs more appealing to(吸引) young people.
In conclusion, with technological improvement and government support, NEVs are made to change how we travel, making our cities cleaner and our future brighter.

单元语法专题训练
被动语态(Ⅱ)
一般过去时的被动语态
1．构成：be(was/were)＋及物动词的过去分词
2．句式变化：
肯定句：主语＋was/were＋及物动词的过去分词＋其他．如：
They were invented by Thomas Edison.它们是由托马斯·爱迪生发明的。
否定句：主语＋was/were＋not＋及物动词的过去分词＋其他．如：
They weren't invented by Thomas Edison.它们不是由托马斯·爱迪生发明的。
一般疑问句：Was/Were＋主语＋及物动词的过去分词＋其他？
其肯定回答为：Yes，主语＋was/were.；否定回答为No，主语＋was/were＋not.如：
—Were they invented by Thomas Edison？它们是由托马斯·爱迪生发明的吗？
—Yes，they were./No，they weren't.是的。/不是。

1．某些可以用well、easily等修饰的不及物动词，如sell、wash、clean、ride、write等，和某些系动词，如 look、sound、smell、taste、feel等，往往用主动形式表示被动意义。如：

3．接双宾语的动词变为被动语态，直接宾语(物)作被动语态的主语时，动词后面要用介词，这个介词是由与其搭配的动词决定的。如：
He sent me a book.→A book was sent to me (by him).一本书被他送给了我。
4．一些短语动词用于被动语态时，短语动词应当看作一个整体，而不能丢掉其中的介词或副词。如：

(河北石家庄期中)阅读下面短文，简略回答问题。
After a game like football, the players might get an X ray in the hospital if they hurt their legs or arms.A dentist can use X rays to look at teeth.And airport workers use an X ray machine to check objects before a plane leaves.Nowadays, X ray technology is widely used in medicine and other fields.
X rays were first discovered by a German scientist, Wilhelm Conrad Rontgen(1845—1923).He found them quite by accident in 1895.One day, he discovered that an unknown kind of radiation(放射线) could hardly pass through hard objects like bones.Later, Rontgen took a photo of his wife's hand.It clearly showed her ring and her bones.That was the first X ray photo in the world.
Why is there an “X” in the word X ray It's because Rontgen couldn't explain exactly how it worked.He just knew that X rays were new and useful for science.In fact, X rays soon became an important tool in medicine.With the help of X rays, doctors could see inside the human body for the first time without surgery(外科手术).
Rontgen was awarded the first Nobel Prize(诺贝尔奖) in physics in 1901 for his discovery.When he was asked what he was thinking at the moment of discovery, he replied, “I didn't think.I investigated(研究).” Rontgen gave away his Nobel Prize money to his university.And he never took out any patents(专利权) on X rays, to make sure that the world could freely make use of his discovery.

These days, people show all kinds of things on the internet like delicious food, nice clothes, wonderful holidays and so on.Now showing the number of steps is becoming popular.
Now more and more people find it important to be in good health.To keep fit, many people go to work on foot.When they start walking, they open the step counter app(计步器应用程序) on the phones to record how many steps they walk that day.After a day's walk, some people show the number on the internet.This can make them learn from each other and keep exercising.
“This helps me to exercise much and keep a good habit，” Miss Liu said.“I can also talk about how to keep healthy with my friends on the internet.We can encourage each other to keep exercising.”
Now Mr Wu likes to exercise.But in the past he found it hard to keep it every day.“After I use the step counter app, everything becomes different.It is great to exercise with my friends.I really like it．Sometimes there are prizes for those who walk more steps，” he said.
【主旨大意】 本文主要介绍了计步器应用程序如何通过记录步数来帮助人们养成锻炼习惯、保持健康，并促进朋友间的相互鼓励。
1．What can't we know from the second paragraph B
A．Why many people go to work on foot.
B．How people show the number of steps on the internet.
C．How people use the step counter app.
D．Why people show the number of steps on the internet.
细节理解题。根据“To keep fit, many people go to work on foot.”可知，第二段提到了为什么许多人步行去上班；“When they start walking, they open the step counter app on the phones to record how many steps they walk that day”可知，第二段提到了人们如何使用计步器；根据“This can make them learn from each other and keep exercising.”可知，第二段提到了为什么人们在网上显示步数，但并未具体说明他们是“如何”把步数发到网上的，因此选项B所说的“如何展示步数”从文中无法得知。
2．The underlined word “it” refers to A．
A．exercising with friends
B．being healthy
C．the prize
D．the step counter app
代词指代题。根据“It is great to exercise with my friends.I really like it．”可知，此处it指的是前文提到的“exercise with my friends”。
3．What's the structure(结构) of the text？A
　　　　　 　　　　　 　　　
A．①/②③④ B．①②/③④
C．①/②③/④ D．①②③/④
篇章结构题。通读全文可知，第一段引入了“使用计步应用程序变得越来越流行”的现象；第二段解释原因(健康重要性、使用app记录)；第三段、第四段引用两人事例说明好处。所以该篇文章的结构是：总分结构。

阅读下面短文，简略回答问题。
New Energy Vehicles: Driving
Towards a Greener Future
In recent years, new energy vehicles(NEVs), especially electric cars(EVs, 电车), have become a hot topic worldwide.As countries want to reduce air pollution and control climate change, NEVs are seen as a key way.China, for example, has taken a leading role in this field, creating the world's largest EV market.In 2024, 40% of the 753，000 EVs sold worldwide were sold in China, far more than other countries.
NEVs are environmentally friendly.Unlike traditional fossil fuel cars(油车), which emit harmful gases, EVs produce zero tailpipe pollution.Charging(充电) an EV is also cheaper than fueling a gasoline car.As Wu Hao, an EV owner in China, said “Charging costs much less than buying gas.” Additionally, governments encourage people to buy NEVs.
However, there were some challenges.A few years ago, finding charging stations was difficult, and EVs couldn't travel long distances.But progress has been made.China built over 167，000 charging stations, forming the world's largest EV charging network.Battery technology is also improved, allowing newer models to drive farther on a single charge.Many believe autonomous driving and advanced battery systems are making NEVs more appealing to(吸引) young people.
In conclusion, with technological improvement and government support, NEVs are made to change how we travel, making our cities cleaner and our future brighter.
1．How many electric cars were sold in China in 2024
301，200.
2．According to Wu Hao, why are electric cars better than traditional fossil fuel cars
Charging(an_EV)_is_cheaper./Charging_costs_much_less_than_buying_gas.
3．What were the challenges of electric cars a few years ago
Finding_charging_stations_and_driving_long_distances.
4．What makes NEVs more appealing to young people
Autonomous_driving_and_advanced_battery_systems.
5．What do you think of New Energy Vehicles
They_can_save_energy./Greener.(开放性题目，言之有理即可)

否定句：主语＋was/were＋not＋及物动词的过去分词＋其他．如：
They weren't invented by Thomas Edison.它们不是由托马斯·爱迪生发明的。
一般疑问句：Was/Were＋主语＋及物动词的过去分词＋其他？
其肯定回答为：Yes，主语＋was/were.；否定回答为No，主语＋was/were＋not.如：
—Were they invented by Thomas Edison？它们是由托马斯·爱迪生发明的吗？

According to a latest report，a few schools in China are using a kind of very special uniform to watch their students' daily life and stop them from playing truant(旷课).
Such uniforms have tracking chips(追踪芯片) in them which can record the time and date a student enters the school and a short video，parents can see through a mobile app.
Once a student doesn't have class without asking for leave，an alarm will be caused to tell both teachers and parents.And a voice alarm will go off as long as a student leaves school without being allowed.A GPS system also follows a student's movements once he has left the school.
Eleven schools in Guizhou have used the uniforms which are developed by Guizhou Guanyu Technology.But the company's project manager said the school wouldn't use the tracking system during out of school hours.The project manager said that fewer and fewer students had been absent since the uniforms were used in some schools.
However，the uniforms have been criticized(批评) on social media.“If you were a child，would you like to be watched 24 hours a day？” one Weibo user asked.“Don't children have human rights and privacy？” added another user.
A headmaster in Guizhou said that although teachers were able to track students at all times，they did not use this technology often.
“We choose not to check the position of students after school，but when the students are missing and playing truant，the uniforms help to find out where they are，” the headmaster said.

(河北石家庄期中)阅读下面短文，简略回答问题。
After a game like football, the players might get an X ray in the hospital if they hurt their legs or arms.A dentist can use X rays to look at teeth.And airport workers use an X ray machine to check objects before a plane leaves.Nowadays, X ray technology is widely used in medicine and other fields.
X rays were first discovered by a German scientist, Wilhelm Conrad Rontgen(1845—1923).He found them quite by accident in 1895.One day, he discovered that an unknown kind of radiation(放射线) could hardly pass through hard objects like bones.Later, Rontgen took a photo of his wife's hand.It clearly showed her ring and her bones.That was the first X ray photo in the world.
Why is there an “X” in the word X ray It's because Rontgen couldn't explain exactly how it worked.He just knew that X rays were new and useful for science.In fact, X rays soon became an important tool in medicine.With the help of X rays, doctors could see inside the human body for the first time without surgery(外科手术).
Rontgen was awarded the first Nobel Prize(诺贝尔奖) in physics in 1901 for his discovery.When he was asked what he was thinking at the moment of discovery, he replied, “I didn't think.I investigated(研究).” Rontgen gave away his Nobel Prize money to his university.And he never took out any patents(专利权) on X rays, to make sure that the world could freely make use of his discovery.
1．Where is X ray technology widely used
In_medicine_and_other_fields.
2．When were X rays discovered
In_1895.
3．What was in the first X ray photo in the world
It_was_Rontgen's_wife's_hand.
4．Why did Rontgen name the ray “X ray”？
