二、完形填空（共15小题; 每小题1分, 满分15分）
Curiosity is often called the “engine of progress”. It drives humans to explore, discover, and create. From ancient times to the present, curious minds have 11 the world we live in today.
When Isaac Newton saw an apple fall from a tree, he didn’t ignore it. Instead, he felt 12 and asked, “Why does it fall down ” This question led him to 13 the theory of gravity. Similarly, Archimedes was curious about the water rising when he got into a bath. His 14 led to the discovery of buoyancy (浮力), which is still used in physics today.
In daily life, curiosity helps us learn better. A 2014 study 15 that curious people remember information 30% better than others. This is because curiosity makes the brain more 16 to new knowledge. For students, staying curious can 17 them to ask more questions and find answers on their own.
Curiosity also brings joy. Think about how a child 18 hours playing with a toy to figure out how it works. That joy of 19 is the same feeling scientists get when they make a new discovery. Especially, it’s a 20 that keeps us going even when things are difficult.
However, curiosity isn’t just for great scientists. It’s for everyone. Whether you’re 21 how a phone works or why stars twinkle, asking “why” is the first step to learning. As the saying goes, “The important thing is not to stop 22 .”
So, let’s keep our curious minds alive. Ask questions, 23 experiments, and never be afraid to explore. You never know what amazing things you might 24 or how your curiosity could 25 the world.

三、阅读理解（共两节, 20小题; 每小题2分, 满分40分）
第一节: 阅读下面短文, 从每题所给的A、B、C、D四个选项中, 选出最佳选项。
A
In the past you could draw anything you wanted on a computer screen and then print it out on a piece of paper—a flat piece of paper. But imagine being able to print something that is three-dimensional—3D．Would you like to design an object, such as a cup or a toy, and then “print” it out Well, there is the technology to help you do this—to produce even a whole house!
3D printers might be the size of a suitcase or even a small room, depending on the object they are made to produce. You make a 3D design on your computer and send it to the printer. Inside the machine, the object you have designed is made as one object.
So how is this being used In medicine, 3D printing is often used to make teeth. The dentist takes a 3D image, something like a photo of the real tooth and a new one is printed in that exact shape. Then you might also want to print a mobile phone cover or a special pair of shoes.
Scientists are taking this even further. They have made a bicycle that just needs a chain and two tires (轮胎). Car parts have been made for a while, and now they are even making a body of a whole car!
But imagine how printing a whole house might help people build houses. A Chinese company has made houses using a giant 3D printer. They use a mixture that includes concrete (混凝土) and recycled building waste.
This is a good thing, as it helps the environment. They believe that their method of printing houses is cheaper, faster, less dusty and less noisy than the ordinary way that houses are built.
It seems that 3D printing technology will change our world, and China is leading the way.
26．3D________ enables you to “print” out many objects you design on your computer.
A．screen B．product C．paper D．technology
27．The size of a 3D printer might be________ according to the object they design.
A．changeable B．always small C．seldom big D．the same
28．In medicine, 3D printing is often used to print________ in the exact shapes.
A．dentists B．teeth
C．photos D．mobile phone covers
29．Scientists are taking this even further. Here “this” probably refers to “________”.
A．a pair of shoes B．the printing
C．a new bicycle D．a whole car
30．Which of the following can be the best title for this passage
A．Use the 3D printing technology to build houses.
B．China is now ready to produce 3D printers.
C．The 3D technology will change our world.
D．3D printing technology protects the environment.
B
No matter how you do it, booking holidays can be a headache. It used to need a visit to a travel agent (旅行代理人)… Later, online travel agents showed up, allowing people to plan trips from the comfort of their own homes. Now, they are promising to handle the brainwork, too, with the help of AI. Expedia, for example, has introduced Romie, its “ AI-powered travel buddy (伙伴). ” has brought out TripGenie.
Many people want AI to save them from boring tasks. This may explain why AI trip planners are drawing attention. They’re perfect for those who go mad when booking holidays.
But are these AI booking agents reliable (可靠的) Some have tried them out. When a couple asked TripGenie to find a romantic (浪漫的) hotel in Paris, its top suggestion was by the airport. Well, perhaps the AI agent is still in its early days, they said.
Tools like TripGenie are facing competition from AI companies, too. OpenAI, for example, is testing its system. The AIbot is designed to “mimic (模仿) a human’s use of the Web.” When asked about that Paris trip, it suggests places with a view of the Eiffel Tower. Some researchers think OpenAI might soon change the online travel agents’ market.
________. Air Canada got in trouble after its chatbot wrongly promised a user a discount (折扣). Could AI agents be fooled into booking a more expensive flight Would anyone feel safe giving his or her credit card information to an AI agent then
AI agents may also have difficulty understanding the endless variety (不同种类) of people’s tastes. Not everyone finds an expensive view of a metal tower romantic. One couple—the groom (新郎) Icelandic and the bride (新娘) French—recently got married on a flight between their countries. A hotel room by Paris Charles de Gaulle Airport might have suited them better.
31．Why does the author say “booking holidays can be a headache” in paragraph 1
A．Because it is always expensive.
B．Because it used to need going to a travel agent and now there are too many choices.
C．Because AI is not helpful at all.
D．Because people don’t like to travel.
32．What is Romie
A．An AI-powered travel helper from Expedia. B．A travel agent from .
C．A new airport in Paris. D．A chatbot from OpenAI.
33．Which of the following can be put in ________
A．Planning a trip is very popular now
B．Some users worry about slow replies from AI booking agents
C．AI booking agents can help us get cheap tickets
D．One problem with AI booking agents is that they make mistakes
34．The writer talks about the couple who married on a plane in the last paragraph to show that ________ .
A．airport hotels are usually very romantic
B．flying between countries is a good way to travel
C．TripGenie’s suggestion is reliable
D．different people may have special needs that AI doesn’t understand
35．What is the main purpose (目的) of the passage
A．To suggest a new AI travel agent called Romie.
B．To explain how AI travel agents work and study.
C．To discuss whether AI travel agents are reliable.
D．To encourage people to use AI to book holidays.
C
How Students Can Practice Environmental Protection
With the development of the world, environmental problems have become more and more serious. As students, we have a responsibility to protect the environment. There are many simple ways we can practice environmental protection in our daily lives.
First, we can save paper. Every year, a large number of trees are cut down to make paper. We can use both sides of a piece of paper when doing homework or taking notes. We can also reuse old notebooks by using the blank pages. In addition, we can send e-mails instead of writing letters to our friends, which can save a lot of paper.
Second, we can save electricity. We should turn off the lights, computers and air conditioners when we leave the classroom or our rooms. We can also use energy-saving bulbs, which use less electricity than ordinary bulbs. During the day, we can open the curtains to let in natural light instead of turning on the lights.
Third, we can reduce waste. We can bring our own shopping bags when going shopping instead of using plastic bags. Plastic bags are harmful to the environment because they take a long time to decompose. We can also separate our waste into different categories, such as recyclable waste and non-recyclable waste. This makes it easier for workers to recycle the waste.
Finally, we can plant trees. Trees can absorb carbon dioxide and release oxygen, which is good for the air. Every spring, many schools organize tree-planting activities. We can take part in these activities and plant more trees in our community.
Protecting the environment is not a difficult task. It requires our efforts every day. If every student can do a little bit for the environment, we will have a better world.
36．Why should we save paper according to the passage
A．Because paper is expensive. B．Because a lot of trees are cut down to make paper.
C．Because we don’t have enough paper. D．Because paper is not easy to use.
37．What can we do to save electricity
A．Use ordinary bulbs instead of energy-saving bulbs. B．Keep the lights on when we leave the room.
C．Use natural light during the day. D．Keep the air conditioner on all day.
38．Why are plastic bags harmful to the environment
A．Because they are too expensive. B．Because they take a long time to decompose.
C．Because they are not easy to carry. D．Because they are not strong enough.
39．What can trees do for the environment
A．They can absorb oxygen and release carbon dioxide.
B．They can absorb air and release water.
C．They can absorb water and release air.
D．They can absorb carbon dioxide and release oxygen.
40．What is the main idea of the passage
A．Environmental problems are very serious.
B．Schools should organize more activities.
C．Students can practice environmental protection in many simple ways.
D．We should plant more trees.
第二节: 阅读下面短文, 从短文后所给的选项中选出能填入短文空白处的最佳选项, 使短文通顺连贯, 其中有两项是多余选项。
Water is important and necessary for life. We drink it and use it to wash, and it helps plants grow. 41 But in our daily lives, we often waste water without knowing it.
When we brush our teeth, do we always remember to turn off the tap Many don’t. 42 Just a little water each time adds up to a lot over days. It’s such an easy way to waste water.
43 Some people think running water cleans dishes better, so they keep it running when they wash dishes. In this way, they waste a lot of valuable water.
Watering plants at noon is also a mistake. The strong sun makes much of the water turn into steam quickly, leaving plants thirsty. 44
The good news is that we can still make a difference.
45 For example, take shorter showers or collect rainwater for plants. Every effort counts. If we all do our part, we can save a lot of water and protect water resources.
A．This is a really bad habit.
B．We can start with small changes.
C．It’s used in almost every part of our lives.
D．As a result, they may not grow well.
E．But they don’t realize how wasteful this is.
F．People hardly notice how much water they waste.
G．Washing dishes is another way to waste a lot of water.

Some of them were dying. I began to worry because I didn’t want to get sick or die. I also considered what I should do to save my friends. So I decided to do some research (研究) for my underwater life.
My research started. At first, I noticed there were many bottles, plastic bags and other kinds of rubbish in the water. Then I went on. I got closer and noticed a man pouring polluted things into the water. They flowed everywhere. Other people saw him do this and they followed him. I found that these things smelled strange. Then I tasted them. They made me feel terrible. I hated them! I really wanted to tell them that these things were killing us! But I couldn’t. I thought the government should make some rules to stop pollution from happening again.
I think it is so stupid of people to do bad things to the earth that they are living on! I can’t understand why they are doing these. People should care about the environment. If they do that, we will not have anything to worry about. I suggest they take my advice. If so, I believe that everyone will live a happy life.

二、完形填空（共15小题; 每小题1分, 满分15分）
Curiosity is often called the “engine of progress”. It drives humans to explore, discover, and create. From ancient times to the present, curious minds have 11 the world we live in today.
When Isaac Newton saw an apple fall from a tree, he didn’t ignore it. Instead, he felt 12 and asked, “Why does it fall down ” This question led him to 13 the theory of gravity. Similarly, Archimedes was curious about the water rising when he got into a bath. His 14 led to the discovery of buoyancy (浮力), which is still used in physics today.
In daily life, curiosity helps us learn better. A 2014 study 15 that curious people remember information 30% better than others. This is because curiosity makes the brain more 16 to new knowledge. For students, staying curious can 17 them to ask more questions and find answers on their own.
Curiosity also brings joy. Think about how a child 18 hours playing with a toy to figure out how it works. That joy of 19 is the same feeling scientists get when they make a new discovery. Especially, it’s a 20 that keeps us going even when things are difficult.
However, curiosity isn’t just for great scientists. It’s for everyone. Whether you’re 21 how a phone works or why stars twinkle, asking “why” is the first step to learning. As the saying goes, “The important thing is not to stop 22 .”
So, let’s keep our curious minds alive. Ask questions, 23 experiments, and never be afraid to explore. You never know what amazing things you might 24 or how your curiosity could 25 the world.

第一节: 阅读下面短文, 从每题所给的A、B、C、D四个选项中, 选出最佳选项。
A
In the past you could draw anything you wanted on a computer screen and then print it out on a piece of paper—a flat piece of paper. But imagine being able to print something that is three-dimensional—3D．Would you like to design an object, such as a cup or a toy, and then “print” it out Well, there is the technology to help you do this—to produce even a whole house!
3D printers might be the size of a suitcase or even a small room, depending on the object they are made to produce. You make a 3D design on your computer and send it to the printer. Inside the machine, the object you have designed is made as one object.
So how is this being used In medicine, 3D printing is often used to make teeth. The dentist takes a 3D image, something like a photo of the real tooth and a new one is printed in that exact shape. Then you might also want to print a mobile phone cover or a special pair of shoes.
Scientists are taking this even further. They have made a bicycle that just needs a chain and two tires (轮胎). Car parts have been made for a while, and now they are even making a body of a whole car!
But imagine how printing a whole house might help people build houses. A Chinese company has made houses using a giant 3D printer. They use a mixture that includes concrete (混凝土) and recycled building waste.
This is a good thing, as it helps the environment. They believe that their method of printing houses is cheaper, faster, less dusty and less noisy than the ordinary way that houses are built.
It seems that 3D printing technology will change our world, and China is leading the way.
26．3D________ enables you to “print” out many objects you design on your computer.
A．screen B．product C．paper D．technology
27．The size of a 3D printer might be________ according to the object they design.
A．changeable B．always small C．seldom big D．the same
28．In medicine, 3D printing is often used to print________ in the exact shapes.
A．dentists B．teeth
C．photos D．mobile phone covers
29．Scientists are taking this even further. Here “this” probably refers to “________”.
A．a pair of shoes B．the printing
C．a new bicycle D．a whole car
30．Which of the following can be the best title for this passage
A．Use the 3D printing technology to build houses.
B．China is now ready to produce 3D printers.
C．The 3D technology will change our world.
D．3D printing technology protects the environment.

No matter how you do it, booking holidays can be a headache. It used to need a visit to a travel agent (旅行代理人)… Later, online travel agents showed up, allowing people to plan trips from the comfort of their own homes. Now, they are promising to handle the brainwork, too, with the help of AI. Expedia, for example, has introduced Romie, its “ AI-powered travel buddy (伙伴). ” has brought out TripGenie.
Many people want AI to save them from boring tasks. This may explain why AI trip planners are drawing attention. They’re perfect for those who go mad when booking holidays.
But are these AI booking agents reliable (可靠的) Some have tried them out. When a couple asked TripGenie to find a romantic (浪漫的) hotel in Paris, its top suggestion was by the airport. Well, perhaps the AI agent is still in its early days, they said.
Tools like TripGenie are facing competition from AI companies, too. OpenAI, for example, is testing its system. The AIbot is designed to “mimic (模仿) a human’s use of the Web.” When asked about that Paris trip, it suggests places with a view of the Eiffel Tower. Some researchers think OpenAI might soon change the online travel agents’ market.
________. Air Canada got in trouble after its chatbot wrongly promised a user a discount (折扣). Could AI agents be fooled into booking a more expensive flight Would anyone feel safe giving his or her credit card information to an AI agent then
AI agents may also have difficulty understanding the endless variety (不同种类) of people’s tastes. Not everyone finds an expensive view of a metal tower romantic. One couple—the groom (新郎) Icelandic and the bride (新娘) French—recently got married on a flight between their countries. A hotel room by Paris Charles de Gaulle Airport might have suited them better.
31．Why does the author say “booking holidays can be a headache” in paragraph 1

B．Because it used to need going to a travel agent and now there are too many choices.
C．Because AI is not helpful at all.
D．Because people don’t like to travel.
32．What is Romie
A．An AI-powered travel helper from Expedia. B．A travel agent from .
C．A new airport in Paris. D．A chatbot from OpenAI.
33．Which of the following can be put in ________
A．Planning a trip is very popular now
B．Some users worry about slow replies from AI booking agents
C．AI booking agents can help us get cheap tickets
D．One problem with AI booking agents is that they make mistakes
34．The writer talks about the couple who married on a plane in the last paragraph to show that ________ .
A．airport hotels are usually very romantic
B．flying between countries is a good way to travel
C．TripGenie’s suggestion is reliable
D．different people may have special needs that AI doesn’t understand
35．What is the main purpose (目的) of the passage
A．To suggest a new AI travel agent called Romie.
B．To explain how AI travel agents work and study.
C．To discuss whether AI travel agents are reliable.
D．To encourage people to use AI to book holidays.

How Students Can Practice Environmental Protection
With the development of the world, environmental problems have become more and more serious. As students, we have a responsibility to protect the environment. There are many simple ways we can practice environmental protection in our daily lives.
First, we can save paper. Every year, a large number of trees are cut down to make paper. We can use both sides of a piece of paper when doing homework or taking notes. We can also reuse old notebooks by using the blank pages. In addition, we can send e-mails instead of writing letters to our friends, which can save a lot of paper.
Second, we can save electricity. We should turn off the lights, computers and air conditioners when we leave the classroom or our rooms. We can also use energy-saving bulbs, which use less electricity than ordinary bulbs. During the day, we can open the curtains to let in natural light instead of turning on the lights.
Third, we can reduce waste. We can bring our own shopping bags when going shopping instead of using plastic bags. Plastic bags are harmful to the environment because they take a long time to decompose. We can also separate our waste into different categories, such as recyclable waste and non-recyclable waste. This makes it easier for workers to recycle the waste.
Finally, we can plant trees. Trees can absorb carbon dioxide and release oxygen, which is good for the air. Every spring, many schools organize tree-planting activities. We can take part in these activities and plant more trees in our community.
Protecting the environment is not a difficult task. It requires our efforts every day. If every student can do a little bit for the environment, we will have a better world.
36．Why should we save paper according to the passage
A．Because paper is expensive. B．Because a lot of trees are cut down to make paper.
C．Because we don’t have enough paper. D．Because paper is not easy to use.
37．What can we do to save electricity
A．Use ordinary bulbs instead of energy-saving bulbs. B．Keep the lights on when we leave the room.
C．Use natural light during the day. D．Keep the air conditioner on all day.
38．Why are plastic bags harmful to the environment
A．Because they are too expensive. B．Because they take a long time to decompose.
C．Because they are not easy to carry. D．Because they are not strong enough.
39．What can trees do for the environment
A．They can absorb oxygen and release carbon dioxide.
B．They can absorb air and release water.
C．They can absorb water and release air.
D．They can absorb carbon dioxide and release oxygen.
40．What is the main idea of the passage
A．Environmental problems are very serious.
B．Schools should organize more activities.
C．Students can practice environmental protection in many simple ways.
D．We should plant more trees.

Water is important and necessary for life. We drink it and use it to wash, and it helps plants grow. 41 But in our daily lives, we often waste water without knowing it.
When we brush our teeth, do we always remember to turn off the tap Many don’t. 42 Just a little water each time adds up to a lot over days. It’s such an easy way to waste water.
43 Some people think running water cleans dishes better, so they keep it running when they wash dishes. In this way, they waste a lot of valuable water.
Watering plants at noon is also a mistake. The strong sun makes much of the water turn into steam quickly, leaving plants thirsty. 44
The good news is that we can still make a difference.
45 For example, take shorter showers or collect rainwater for plants. Every effort counts. If we all do our part, we can save a lot of water and protect water resources.
A．This is a really bad habit.
B．We can start with small changes.
C．It’s used in almost every part of our lives.
D．As a result, they may not grow well.
E．But they don’t realize how wasteful this is.
F．People hardly notice how much water they waste.

根据短文内容，回答问题。
Hello, everyone. My name is Jack. I am a fish. However, I feel very terrible. I want to share my life with you. I hope everyone can listen to me and help us.
One fresh sunny day, while I was swimming in the water, I felt something special going through my gills (鳃). It was a different kind of water. I also found many of my friends became sick. Some of them were dying. I began to worry because I didn’t want to get sick or die. I also considered what I should do to save my friends. So I decided to do some research (研究) for my underwater life.
My research started. At first, I noticed there were many bottles, plastic bags and other kinds of rubbish in the water. Then I went on. I got closer and noticed a man pouring polluted things into the water. They flowed everywhere. Other people saw him do this and they followed him. I found that these things smelled strange. Then I tasted them. They made me feel terrible. I hated them! I really wanted to tell them that these things were killing us! But I couldn’t. I thought the government should make some rules to stop pollution from happening again.
I think it is so stupid of people to do bad things to the earth that they are living on! I can’t understand why they are doing these. People should care about the environment. If they do that, we will not have anything to worry about. I suggest they take my advice. If so, I believe that everyone will live a happy life.
