文档简介
Passage 1
Like any doctor，Jacques Fellay wants to give his patients the best care.Hidden inside our bodies are genetic(基因的)markers that can tell him which patients could probably have diseases such as AIDS and provide early treatments.However，there are worries for Fellay：they contain sensitive details that could lead to embarrassment，discrimination or even worse.
A new kind of encryption，Fully Homomorphic Encryption (FHE)(完全同态加密)，is making it possible for data users to run multiple operations on genetic data without seeing the contents.This can help end big data's privacy problems，and Fellay's patients can be some of the first to benefit.
In 1978，the concept of Homomorphic Encryption(HE)was firstly proposed.According to it，one could encrypt and share data with others，who could analyze and perform calculations on the data with no idea what it means.After getting the data back，the data user could simply arrive at the result using the secret key and it will make total sense.
In 2009，Craig Gentry firstly provided a workable FHE program.Like HE，it rests on a mathematical idea called a homomorphism，which mostly relies on using algebra(代数)to map data from one form to another without changing its underlying structure.However，it supports multiple operations on encrypted data，rather than only one calculation in HE.
Later，Gentry went on to work at IBM，which now has complicated FHE tools to run encrypted data.In the medical field，for example，it detected signs of pneumonia(肺炎)infection by applying FHE to analyze the encrypted CT scans of more than 1，500 people's lungs.In a paper published in October 2021，the team used FHE to collect data from multiple sources and predicted the effect of cancer treatments or the process of HIV infection，as in Fellay's case.
Workable，but still slow: calculations on the FHE encrypted data could take millions of times longer than those on raw data.But，as Goldwasser said，“If you believe that security is not a plus，but it's a must，then in some sense there is no overhead.”

Passage 2
When I was about six years old，my mother came home one day and found that I had collected half a dozen babies of the neighbourhood—all of them too young to walk—and had them sitting before me on the floor while I was teaching them to wave their arms.When she asked the explanation of this，I informed her that it was my school of dance.She was amused，and placing herself at the piano.She began to play for me.This school continued and became very popular.Later on，little girls of the neighbourhood came and their parents paid me a small sum to teach them.This was the beginning of what afterwards proved a very profitable occupation.
My mother took me to a famous ballet teacher，but his lessons did not please me.When the teacher told me to stand on my toes(脚趾)I asked him why，and when he replied“Because it is beautiful”，I said that it was ugly and against nature and after the third lesson I left his class，never to return.This stiff(僵硬)and commonplace gymnastics which he called dancing only disturbed my dream.I dreamed of a different dance.I did not know just what it would be，but I was feeling out towards an invisible world into which I guessed I might enter if I found the key.
My art was already in me when I was a little girl，and it was owing to the heroic and adventurous spirit of my mother that it was not prevented.I believe that whatever the child is going to do in life should be begun when it is very young.I wonder how many parents realize that by the so called education they are giving their children，they are only driving them into the commonplace，and taking away from them any chance of doing anything beautiful or original.
5．What was the writer doing when her mother came home one day
A．Teaching some babies to dance.
B．Directing some babies to walk.
C．Getting some babies together.
D．Making some babies sit still.
6．How did the writer find the ballet

C．Graceful and original.
D．Dreamlike and gymnastic.
7．What did the writer think she owed her success in art to
A．The ballet classes she had attended.
B．Her inborn talent and great efforts.
C．The lucky chance her parents gave her.
D．Her mother's support and understanding.
8．What's the main idea of the text
A．Children should be encouraged to be educated as early as possible.
B．Children should be driven to develop their interest in art at an early age.
C．Parents should discover and develop their young children's natural gift.
D．Parents should instruct their children to decide on a promising occupation.
Passage 3
Endangered polar bears are breeding(繁殖)with grizzly bears(灰熊)，creating “pizzly” bears，which is being driven by climate change，scientists say.
As the world warms and Arctic sea ice thins，starving polar bears are being forced ever further south，where they meet grizzlies，whose ranges are expanding northwards.And with that growing contact between the two come increasing hybrids(杂交种)．
With characteristics that could give the hybrids an advantage in warming northern habitats，some scientists guess that they could be here to stay.“Usually，hybrids aren't better suited to their environments than their parents，but these hybrids are able to search for a broader range of food sources，”Larisa DeSantis，an associate professor of biological sciences at Vanderbilt University，told LiveScience.
The rise of“pizzly”bears appears with polar bears' decline：their numbers are estimated to decrease by more than 30% in the next 30 years.This sudden fall is linked partly to“pizzly”bears taking up polar bears' ranges，where they outcompete them，but also to polar bears' highly specialized diets.
“Polar bears mainly consumed soft foods even during the Medieval Warm Period，a previous period of rapid warming.”DeSantis said，referring to fat meals such as seals.“Although all of these starving polar bears are trying to find alternative food sources，like seabird eggs，it could beatippingpoint for their survival.”Actually，the calories they gain from these sources do not balance out those they burn from searching for them.This could result in a habitat ready for the hybrids to move in and take over，leading to a loss in biodiversity if polar bears are replaced.
“We're having massive impacts with climate change on species，”DeSantis said.“The polar bear is telling us how bad things are.In some sense，‘pizzly’bears could be a sad but necessary compromise given current warming trends.”
9．Why do polar bears move further south
A．To create hybrids. B．To expand territory.
C．To relieve hunger. D．To contact grizzlies.
10．What makes“pizzly”bears adapt to natural surroundings better than their parents
A．Broader habitats. B．More food options.
C．Climate preference. D．Improved breeding ability.
11．What does the underlined phrase“a tipping point” in Paragraph 5 refer to
A．A rare chance.
B．A critical stage.
C．A positive factor.
D．A constant change.
12．What's the main idea of the text
A．Polar bears are changing diets for climate change.
B．Polar bears have already adjusted to climate change.
C．“Pizzly”bears are on the rise because of global warming.

Passage 7
Lam Hon ming，director of the State Key Laboratory at the Chinese University of Hong Kong，is a top expert in soybean(大豆)research.Since 1998，Lam's team has been cooperating with scientists in Chinese mainland.In 2010，he came across Zhang Guohong，an agricultural expert from Gansu，China，at a national soybean conference.With the same major，they hit it off and decided to improve farmers' lives and promote local agriculture.
Farmers in Gansu depend largely on the weather for their livelihood，mainly on rainfall，which is also a cause of severe poorness in the area.In 2016，they developed three new soybean varieties suited to salty soil and rare rainfall of Northwest China.All received official government approval.
As the land in Northwest China is not suitable for the growth of common varieties of soybeans，local farmers never planted soybeans，and it became a major problem for spreading new soybeans.Lam and Zhang increased communication with farmers through various ways.To ensure farmers' income，Lam struck a partnership with a Hong Kong food company that will purchase all soybeans at market price when they are harvested.
By 2020，the planting area of the three approved soybeans in Gansu had gone beyond 2.4 million square kilometers，covering 46 of the province's 80 plus counties，and the output had reached 7.71 million kilograms，adding about 30 million yuan to local farmers' income.
Zhang said that Professor Lam's contribution has greatly pushed the poorness relief and agricultural research in Northwest China.“It is hard to keep doing agricultural research with less funding.And it is more difficult to travel from Hong Kong to the poor areas of the Northwest to do agricultural research，”he added.In the future，Lam will continue to work with mainland scientists and lead more“Hong Kong power”into the development of the country's Northwest.
22．What can we know about the two scientists from Paragraph 1
A．They have been friends since 1998.
B．They both major in agriculture.
C．They once served in the same lab.
D．They met by chance in Hong Kong.
23．What does the underlined word“it”in Paragraph 3 refer to
A．Rainfall is not enough.
B．The locals lived a poor life.
C．Little land is rich in nutrition.
D．The farmers never planted soybeans.
24．What does Paragraph 4 mainly tell us
A．More work needs to be done.
B．All farmers become better off.
C．The two scientists are successful.
D．Soybeans grow throughout Gansu.
25. Which of the following can best describe Lam Hon ming
A．Dependent. B．Honest.
C．Open minded. D．Devoted.
Passage 8
Transport is undergoing a massive transformation so it can meet society's demands for a low carbon economy.Introducing Electric Vehicles (EVs) and reducing gasoline use are helping，but zero carbon hydrogen can speed up both the transition(转变)and long term decarbonization of transport.
In the US，transportation produces the largest share of all greenhouse gas emissions(排放)in the economy at 29%，according to the Environmental Protection Agency.More than 90% of transport fuel is petrol based，but if more vehicles used hydrogen，emissions of this kind would plummet．
However，hydrogen is not considered an ideal replacement for gasoline as an engine fuel for cars because it is harder to store safely.And while Fuel Cell Electric Vehicles (FCEVs) that turn hydrogen into electricity can compete with EVs in performance—and even outcompete them on the range and refill time，extra energy is needed to produce the hydrogen needed for fuel.Also，finding investment for storage，pipelines and fuel stations is still a challenge for many nations.
Currently，governments worldwide are backing green hydrogen projects to reduce greenhouse gas emissions in heavy industries like freight(货运)，steel，and energy storage.But hydrogen transport will need rapid production methods to create the fuel needed for the world's road fleet.
Thankfully，research is advancing all the time.Nanoscale(纳米的)thin films are applied to improving the chemical process to rapidly harvest hydrogen from the sea water.The same technology has been successfully used in solar power devices.Since hydrogen is the most abundant element in the universe and as sea water makes up about 96% of all water on Earth，there is a virtually limitless supply.
Even wastewater and solid waste can create green hydrogen.Researchers at Princeton University are using sunlight to separate hydrogen from industrial wastewater.Chemical plants that currently face high costs for cleaning wastewater could transform it into clean hydrogen supplies.
26．What does the underlined word“plummet”mean in Paragraph 2
A．Stop. B．Decrease.
C．Continue. D．Disappear.
27．What is Paragraph 3 mainly about
A．Ways of storing hydrogen safely.
B．Benefits of fuel cell electric vehicles.
C．Challenges of using hydrogen as car fuel.
D．Differences between gasoline and hydrogen.
28．What makes it more efficient to get hydrogen from the ocean
A．The application of solar power devices.
B．The method of identifying water elements.
C．The invention of the water transport system.
D．The use of the nanoscale thin film technology.
29．Which of the following can be a suitable title for the text
A．Clean Energy Hydrogen Ready to Take Off
B．Traditional Fuels Bound to Reach a Dead End
C．How We Can Generate Energy from Hydrogen
D．What the Future of Transportation May Be like
Passage 9
In the South China Sea，there is a group of Jiaoren，or Chinese mermaids(美人鱼)，whose teardrops become pearls after they fall.To the north of Kunlun Mountains，there's a monster called Xiangliu，which has nine heads with human faces but the body of a snake.
These magic creatures from the ancient book of legends ShanHaiJing，which inspired J．K.Rowling for her FantasticBeastsandWheretoFindThem series，are now brought back to life by a young Chinese girl in her photos.
Chen Xin，who learned painting as a child，said she started the photo series to commemorate(纪念)the days she spent with her grandma.
Every night before she went to sleep，her grandma told her stories in ShanHaiJing.“I remember，especially in the summer nights，my grandma stayed outside to enjoy the light wind，”Chen said.“She sat on a rocking chair while I counted the stars and listened to her stories.” These stories opened her mind to an imaginative world with fantastic creatures.
To design the makeup and look of these creatures，Chen checked documents and combined the images with the appearance of animals.She used various means and materials to make the items look like horns or tails.“I used real yak horns(牦牛角)．It's difficult to fix them onto the head and face of models，as they will drop.So it takes a long time，”Chen said.She also chose places whose geographical conditions met the descriptions of the creatures for photos.“For example，some creatures live in areas surrounded by rocks，so I will try to find such a place，” she said.
Recently，Chen has been working on another two photo series about the 24 solar terms and Chinese food.“I'm happy that more and more people are now paying attention to and falling in love with Chinese traditional culture，”she said.
30．Why does the author write the first paragraph
A．To amuse the readers.
B．To recommend an ancient book.
C．To introduce the topic of the text.
D．To stress the diversity of Chinese culture.
31.Why did Chen start the photo series
A．To become famous.
B．To show off her talent.
C．To spread traditional Chinese culture.
D．To remember the happy days with her grandma.
32. What opened Chen's mind to an imaginative world
A．Chen's carefree childhood.
B．Those peaceful starry nights.
C．One of J．K.Rowling's books.
D．Stories told by Chen's grandma.
33．What's the main idea of Paragraph 5
A．How to draw creatures from ShanHaiJing.
B．The efforts Chen made to bring legendary animals to life.
C．The makeup and look of creatures from ShanHaiJing.
D．Where to find a place to match the creatures from ShanHaiJing.

走入现实的女孩。
30.解析：推理判断题。根据第一段“In the South China Sea，there is a group of Jiaoren，or Chinese mermaids(美人鱼)，whose teardrops become pearls after they fall.To the north of Kunlun Mountains，there's a monster called Xiangliu，which has nine heads with human faces but the body of a snake.(在中国南海，有一群美人鱼，她们的眼泪掉下来就变成了珍珠。在昆仑山的北面，有一种怪物叫“相柳”，它有九个头，长着人面，身体却是蛇。)”第一段作者描述《山海经》里的精怪，形象生动，是为了引出本文的话题——中国女孩陈馨。
答案：C
31.解析：细节理解题。根据第三段“Chen Xin，who learned painting as a child，said she started the photo series to commemorate the days she spent with her grandma(从小学习绘画的陈馨说，她开始拍摄这一系列照片是为了纪念和奶奶一起度过的日子)”可知，陈馨开始拍摄系列照片为了纪念和奶奶在一起的快乐时光。
答案：D
32.解析：细节理解题。根据第四段“These stories opened her mind to an imaginative world with fantastic creatures(这些故事打开了她的心扉，让她看到了一个充满想象力的世界，有着奇妙的生物)”可知，奶奶讲的故事让陈馨的思绪进入了一个充满想象力的世界。
答案：D
33.解析：主旨大意题。通读第五段可知，为了设计这些生物的妆容和外观，陈查阅了相关文档，并将图像与动物的外观相结合。她用各种方法和材料使物品看起来像角或尾巴。她花了很长时间把真正的牦牛角固定在模特的头上和脸上，因为它们会掉下来。她还选择了那些地理条件符合生物描述的地方拍照。因此，本段主要讲陈馨为了让《山海经》里的精怪走入现实所付出的努力。
答案：B
Like any doctor，Jacques Fellay wants to give his patients the best care.Hidden inside our bodies are genetic(基因的)markers that can tell him which patients could probably have diseases such as AIDS and provide early treatments.However，there are worries for Fellay：they contain sensitive details that could lead to embarrassment，discrimination or even worse.
A new kind of encryption，Fully Homomorphic Encryption (FHE)(完全同态加密)，is making it possible for data users to run multiple operations on genetic data without seeing the contents.This can help end big data's privacy problems，and Fellay's patients can be some of the first to benefit.
In 1978，the concept of Homomorphic Encryption(HE)was firstly proposed.According to it，one could encrypt and share data with others，who could analyze and perform calculations on the data with no idea what it means.After getting the data back，the data user could simply arrive at the result using the secret key and it will make total sense.
In 2009，Craig Gentry firstly provided a workable FHE program.Like HE，it rests on a mathematical idea called a homomorphism，which mostly relies on using algebra(代数)to map data from one form to another without changing its underlying structure.However，it supports multiple operations on encrypted data，rather than only one calculation in HE.
Later，Gentry went on to work at IBM，which now has complicated FHE tools to run encrypted data.In the medical field，for example，it detected signs of pneumonia(肺炎)infection by applying FHE to analyze the encrypted CT scans of more than 1，500 people's lungs.In a paper published in October 2021，the team used FHE to collect data from multiple sources and predicted the effect of cancer treatments or the process of HIV infection，as in Fellay's case.
Workable，but still slow: calculations on the FHE encrypted data could take millions of times longer than those on raw data.But，as Goldwasser said，“If you believe that security is not a plus，but it's a must，then in some sense there is no overhead.”
1．What is Fellay concerned about
A．Serious diseases.
B．Sensitive patients.
C．The safety of personal data.
D．The lack of genetic information.
2．In what way is FHE different from HE
A．It speeds up the analyses.
B．It allows more calculations.
C．It prevents direct access to data.
D．It depends on the use of algebra.
3．What is Goldwasser's attitude towards FHE
A．Contradictory. B．Unclear.
C．Favorable. D．Intolerant.
4．What is the main idea of the text
A．FHE protects privacy in the big data era.
B．FHE opens a new world for medical workers.
C．Gentry proposed a new encryption technology.
D．Homomorphic encryption developed over time.
Passage 2
When I was about six years old，my mother came home one day and found that I had collected half a dozen babies of the neighbourhood—all of them too young to walk—and had them sitting before me on the floor while I was teaching them to wave their arms.When she asked the explanation of this，I informed her that it was my school of dance.She was amused，and placing herself at the piano.She began to play for me.This school continued and became very popular.Later on，little girls of the neighbourhood came and their parents paid me a small sum to teach them.This was the beginning of what afterwards proved a very profitable occupation.
My mother took me to a famous ballet teacher，but his lessons did not please me.When the teacher told me to stand on my toes(脚趾)I asked him why，and when he replied“Because it is beautiful”，I said that it was ugly and against nature and after the third lesson I left his class，never to return.This stiff(僵硬)and commonplace gymnastics which he called dancing only disturbed my dream.I dreamed of a different dance.I did not know just what it would be，but I was feeling out towards an invisible world into which I guessed I might enter if I found the key.
My art was already in me when I was a little girl，and it was owing to the heroic and adventurous spirit of my mother that it was not prevented.I believe that whatever the child is going to do in life should be begun when it is very young.I wonder how many parents realize that by the so called education they are giving their children，they are only driving them into the commonplace，and taking away from them any chance of doing anything beautiful or original.
5．What was the writer doing when her mother came home one day

7．What did the writer think she owed her success in art to
A．The ballet classes she had attended.
B．Her inborn talent and great efforts.
C．The lucky chance her parents gave her.
D．Her mother's support and understanding.
8．What's the main idea of the text
A．Children should be encouraged to be educated as early as possible.
B．Children should be driven to develop their interest in art at an early age.
C．Parents should discover and develop their young children's natural gift.
D．Parents should instruct their children to decide on a promising occupation.
Passage 3
Endangered polar bears are breeding(繁殖)with grizzly bears(灰熊)，creating “pizzly” bears，which is being driven by climate change，scientists say.
As the world warms and Arctic sea ice thins，starving polar bears are being forced ever further south，where they meet grizzlies，whose ranges are expanding northwards.And with that growing contact between the two come increasing hybrids(杂交种)．
With characteristics that could give the hybrids an advantage in warming northern habitats，some scientists guess that they could be here to stay.“Usually，hybrids aren't better suited to their environments than their parents，but these hybrids are able to search for a broader range of food sources，”Larisa DeSantis，an associate professor of biological sciences at Vanderbilt University，told LiveScience.
The rise of“pizzly”bears appears with polar bears' decline：their numbers are estimated to decrease by more than 30% in the next 30 years.This sudden fall is linked partly to“pizzly”bears taking up polar bears' ranges，where they outcompete them，but also to polar bears' highly specialized diets.
“Polar bears mainly consumed soft foods even during the Medieval Warm Period，a previous period of rapid warming.”DeSantis said，referring to fat meals such as seals.“Although all of these starving polar bears are trying to find alternative food sources，like seabird eggs，it could beatippingpoint for their survival.”Actually，the calories they gain from these sources do not balance out those they burn from searching for them.This could result in a habitat ready for the hybrids to move in and take over，leading to a loss in biodiversity if polar bears are replaced.
“We're having massive impacts with climate change on species，”DeSantis said.“The polar bear is telling us how bad things are.In some sense，‘pizzly’bears could be a sad but necessary compromise given current warming trends.”
9．Why do polar bears move further south
A．To create hybrids. B．To expand territory.
C．To relieve hunger. D．To contact grizzlies.
10．What makes“pizzly”bears adapt to natural surroundings better than their parents
A．Broader habitats. B．More food options.
C．Climate preference. D．Improved breeding ability.
11．What does the underlined phrase“a tipping point” in Paragraph 5 refer to
A．A rare chance.
B．A critical stage.
C．A positive factor.
D．A constant change.
12．What's the main idea of the text
A．Polar bears are changing diets for climate change.
B．Polar bears have already adjusted to climate change.
C．“Pizzly”bears are on the rise because of global warming.
D．“Pizzly”bears have replaced polar bears for global warming.

Passage 7
Lam Hon ming，director of the State Key Laboratory at the Chinese University of Hong Kong，is a top expert in soybean(大豆)research.Since 1998，Lam's team has been cooperating with scientists in Chinese mainland.In 2010，he came across Zhang Guohong，an agricultural expert from Gansu，China，at a national soybean conference.With the same major，they hit it off and decided to improve farmers' lives and promote local agriculture.
Farmers in Gansu depend largely on the weather for their livelihood，mainly on rainfall，which is also a cause of severe poorness in the area.In 2016，they developed three new soybean varieties suited to salty soil and rare rainfall of Northwest China.All received official government approval.
As the land in Northwest China is not suitable for the growth of common varieties of soybeans，local farmers never planted soybeans，and it became a major problem for spreading new soybeans.Lam and Zhang increased communication with farmers through various ways.To ensure farmers' income，Lam struck a partnership with a Hong Kong food company that will purchase all soybeans at market price when they are harvested.
By 2020，the planting area of the three approved soybeans in Gansu had gone beyond 2.4 million square kilometers，covering 46 of the province's 80 plus counties，and the output had reached 7.71 million kilograms，adding about 30 million yuan to local farmers' income.
Zhang said that Professor Lam's contribution has greatly pushed the poorness relief and agricultural research in Northwest China.“It is hard to keep doing agricultural research with less funding.And it is more difficult to travel from Hong Kong to the poor areas of the Northwest to do agricultural research，”he added.In the future，Lam will continue to work with mainland scientists and lead more“Hong Kong power”into the development of the country's Northwest.
22．What can we know about the two scientists from Paragraph 1
A．They have been friends since 1998.
B．They both major in agriculture.
C．They once served in the same lab.
D．They met by chance in Hong Kong.
23．What does the underlined word“it”in Paragraph 3 refer to
A．Rainfall is not enough.
B．The locals lived a poor life.
C．Little land is rich in nutrition.
D．The farmers never planted soybeans.
24．What does Paragraph 4 mainly tell us
A．More work needs to be done.
B．All farmers become better off.
C．The two scientists are successful.
D．Soybeans grow throughout Gansu.
25. Which of the following can best describe Lam Hon ming
A．Dependent. B．Honest.
C．Open minded. D．Devoted.
Passage 8
Transport is undergoing a massive transformation so it can meet society's demands for a low carbon economy.Introducing Electric Vehicles (EVs) and reducing gasoline use are helping，but zero carbon hydrogen can speed up both the transition(转变)and long term decarbonization of transport.
In the US，transportation produces the largest share of all greenhouse gas emissions(排放)in the economy at 29%，according to the Environmental Protection Agency.More than 90% of transport fuel is petrol based，but if more vehicles used hydrogen，emissions of this kind would plummet．
However，hydrogen is not considered an ideal replacement for gasoline as an engine fuel for cars because it is harder to store safely.And while Fuel Cell Electric Vehicles (FCEVs) that turn hydrogen into electricity can compete with EVs in performance—and even outcompete them on the range and refill time，extra energy is needed to produce the hydrogen needed for fuel.Also，finding investment for storage，pipelines and fuel stations is still a challenge for many nations.
Currently，governments worldwide are backing green hydrogen projects to reduce greenhouse gas emissions in heavy industries like freight(货运)，steel，and energy storage.But hydrogen transport will need rapid production methods to create the fuel needed for the world's road fleet.
Thankfully，research is advancing all the time.Nanoscale(纳米的)thin films are applied to improving the chemical process to rapidly harvest hydrogen from the sea water.The same technology has been successfully used in solar power devices.Since hydrogen is the most abundant element in the universe and as sea water makes up about 96% of all water on Earth，there is a virtually limitless supply.
Even wastewater and solid waste can create green hydrogen.Researchers at Princeton University are using sunlight to separate hydrogen from industrial wastewater.Chemical plants that currently face high costs for cleaning wastewater could transform it into clean hydrogen supplies.
26．What does the underlined word“plummet”mean in Paragraph 2
A．Stop. B．Decrease.
C．Continue. D．Disappear.
27．What is Paragraph 3 mainly about
A．Ways of storing hydrogen safely.
B．Benefits of fuel cell electric vehicles.
C．Challenges of using hydrogen as car fuel.
D．Differences between gasoline and hydrogen.
28．What makes it more efficient to get hydrogen from the ocean
A．The application of solar power devices.
B．The method of identifying water elements.
C．The invention of the water transport system.
D．The use of the nanoscale thin film technology.
29．Which of the following can be a suitable title for the text
A．Clean Energy Hydrogen Ready to Take Off
B．Traditional Fuels Bound to Reach a Dead End
C．How We Can Generate Energy from Hydrogen
D．What the Future of Transportation May Be like
Passage 9
In the South China Sea，there is a group of Jiaoren，or Chinese mermaids(美人鱼)，whose teardrops become pearls after they fall.To the north of Kunlun Mountains，there's a monster called Xiangliu，which has nine heads with human faces but the body of a snake.
These magic creatures from the ancient book of legends ShanHaiJing，which inspired J．K.Rowling for her FantasticBeastsandWheretoFindThem series，are now brought back to life by a young Chinese girl in her photos.
Chen Xin，who learned painting as a child，said she started the photo series to commemorate(纪念)the days she spent with her grandma.
Every night before she went to sleep，her grandma told her stories in ShanHaiJing.“I remember，especially in the summer nights，my grandma stayed outside to enjoy the light wind，”Chen said.“She sat on a rocking chair while I counted the stars and listened to her stories.” These stories opened her mind to an imaginative world with fantastic creatures.
To design the makeup and look of these creatures，Chen checked documents and combined the images with the appearance of animals.She used various means and materials to make the items look like horns or tails.“I used real yak horns(牦牛角)．It's difficult to fix them onto the head and face of models，as they will drop.So it takes a long time，”Chen said.She also chose places whose geographical conditions met the descriptions of the creatures for photos.“For example，some creatures live in areas surrounded by rocks，so I will try to find such a place，” she said.
Recently，Chen has been working on another two photo series about the 24 solar terms and Chinese food.“I'm happy that more and more people are now paying attention to and falling in love with Chinese traditional culture，”she said.
30．Why does the author write the first paragraph
A．To amuse the readers.
B．To recommend an ancient book.
C．To introduce the topic of the text.
D．To stress the diversity of Chinese culture.
31.Why did Chen start the photo series
A．To become famous.
B．To show off her talent.
C．To spread traditional Chinese culture.
D．To remember the happy days with her grandma.
32. What opened Chen's mind to an imaginative world
A．Chen's carefree childhood.
B．Those peaceful starry nights.
C．One of J．K.Rowling's books.
D．Stories told by Chen's grandma.
33．What's the main idea of Paragraph 5
