单元话题阅读理解训练
（2022·江苏·宜兴市万石中学九年级阶段练习）
Next time, when you get stuck(堵塞) behind a slow driver, look at the colour of his car. It will probably be green. American researchers have found that green cars are chosen by stubborn(固执的) drivers who dislike to get out of the way for anybody. They also complain about the way others drive.
The study also shows that bright red cars are usually driven by outgoing people who hate being overtaken(赶超). And, it is said that yellow cars are always in a hurry. Drivers of yellow cars will not wait when they get stuck. They will turn off the road and try to find another way.
Blue is the colour chosen by the relaxed drivers. It’s hardly possible for them to get angry with other drivers and they will almost certainly stop before the red light.
Black was the only colour available when cars were first sold. Many people remember that Henry Ford, the producer of the first cars, once said “Any colour—so long as (只要)it’s black” when someone asked about what colour car he could have. Now black has become a popular colour in some countries.

Mary: Mrs James, there is a colour in each of the sentences. What do they mean

with a green thumb grows plants well and a white lie is not a bad one.
Mary: I’m afraid I don’t understand them all. Would you give me an example for “a white lie”
Mrs James: Certainly. Now I just give you some bread. In fact you don’t like it, but you don’t want to let me know it. Instead you say, “No, thanks. I’m not hungry.” That’s a white lie.
Mary: It sounds very interesting. Thanks very much.
Mrs James: You are welcome. Colours are meaningful. I think you will meet more sentences like these in the future. Please come to me if you have any questions.

（2021·江苏·沭阳县修远中学九年级阶段练习）The world around us is full of colours—the grass is green, and the sky is blue. What a pity it will be if people can not see the colours. But there are people who are blind to certain colours.
Human colour blindness is a strange thing to explain. In a single eye there are millions of very small things called “cones”. They help us to see in bright light and to tell the difference between colours. There are also millions of “rods” which are used for seeing when it is nearly dark. They show us the shape but not the colour.
Some birds and other animals’ eyes have few or no cones, so they cannot see colours. Cats and dogs cannot see colours as well as we can.
Some insects(昆虫) can even see X－rays. Scientists know that there are other colours around us which insects can see but we cannot see.
People have their favourite colours. Blue is often popular because it is the colour of the sky and sea. Green is the colour of nature, it makes us think of grass, field and forest. Yellow is the colour of the sun. Red is the colour of blood and fire. It makes some people think of accidents, danger and blood. Black is the colour of the night. In the dark we cannot see what is around us, so we are sometimes afraid of the unknown and do not like black as a colour.
8．What does the underlined phrase “colour blindness” mean in Chinese
A．夜盲 B．色差 C．色盲 D．色弱
9．Which of the following statements about “cones” and “rods” is RIGHT
A．Some birds can’t see colours because their eyes have no rods.
B．Cones are used for seeing in the dark.
C．Rods help us to see in bright light.
D．Rods show us the shape but not the colour at night.
10．We can find this article in ________ column (栏目) of a magazine.
A．Amazing animals B．Believe it or not C．Do it yourself D．Let’s play
（2022·江苏·南通市新桥中学八年级期中）If you go shopping in any toy store, you can see clearly the different games and toys for boys and girls: there are a lot of pink toys on one side of the store for girls; and dark-coloured cars, guns, and soldiers for boys. Some big stores with toys may even have a pink floor for girls and a blue floor for boys. In fact, it is difficult to buy a toy for a girl that is not pink.
Some people think that too much pink is bad for girls. Sue Palmer, writer of Toxic Childhood, is very worried that most girls over the age of three are crazy about the colour. According to some scientists, this happens for two reasons. Firstly, most companies offer too many products in pink. Also, many parents think their little daughter looks cute in pink. Sue Palmer says that girls at this age cannot make proper decisions by themselves, but the pink can affect the choices and the decisions they will make in the future.
Some parents are worried too—for example, Vanessa Holburn, thirty-two, who has two girls under the age of four. Their bedrooms are a sea of pink and Vanessa is not happy. “Pink says that you are soft and gentle. Blue says that you are strong and powerful. I want my daughters to be strong and powerful. I’m worried that pink will not help them with that,” she says.
But not everyone thinks there’s something wrong with pink. Grayson Turner is a father of three girls and he isn’t worried at all. “People forget that things change all the time,” he says. “My girls used to love pink when they were little, but as they get older, they change.” Turner explains that his twelve-year-old daughter never wears pink clothes any more. “This love of pink is just a fashion and all fashions change,” he adds. “It’s only since the 1940s that people have started dressing girls in pink—before that it was a colour for boys.”
11．Which of the following best shows the structure of the passage
A． B． C． D．
12．According to Grayson Turner, ________.
A．parents needn’t worry about pink toys B．all little kids love the colour pink
C．pink has always been a colour for girls D．his girls now prefer the colour blue
13．The purpose of this passage is to ________.
A．explain why girls are crazy about the colour pink
B．make parents less worried about the colour pink
C．encourage girls to give up playing with pink toys
D．show people’s different opinions about the colour pink
（2021·江苏·扬州市江都区第三中学九年级阶段练习）Many daily American expressions are based on(以……为基础) colours.
Red is a hot colour. Americans often use it to represent heat. When they say “red-hot”, that means they are very angry about something. Loud music is popular with many people. Some may say that such music is red-hot.
Pink is a lighter kind of red. People sometimes say “I’m in the pink” when they are in good health. The expression was first used in America at the beginning of the 20th century. It probably comes from the fact that many babies are born with a nice pink colour that shows that they are in good health.
Blue is a cool colour. The old Blues music in the United States is the opposite of red-hot music. Blues is slow and sad. Someone who is “blue” is very sad.
The colour green is natural for trees and grass. But it is an unnatural colour for humans. A person who has an upset stomach may say “I’m feeling a bit green”. A person on a boat who is feeling very sick from high waves can be said “look very green”. Sometimes a person may be very jealous because he does not have anything as nice as someone has, like a fast new car. That person may say “I’m green with envy”. Some people are green with envy because someone has more dollars or “greenbacks”. Dollars are called greenbacks in American slangs because that is the colour of the bottom of their bank notes.
The colour black is used often in expressions. People may say “it’s a black day” when everything goes wrong on that day.
In some cases, colours describe a situation. Blackouts were common during the World War II. All the lights in a city were turned off at night to make it difficult for enemy planes to find their aims in the dark.
14．What does “I’m in the pink” mean
A．I’m sad . B．I’m happy. C．I’m healthy. D．I’m worried.

A．a red day B．a green day C．a pink day D．a black day

B．If you are blue, you are very happy.
C．Blue and red are both warm colours.

（2021·江苏盐城·九年级阶段练习）Yellow is the colour of sunshine. It has something to do with joy, happiness, and energy. Light yellow is also associated with (和……有关) freshness. Yellow gives us warming feelings, encourages cheerfulness and mental activity, and creates muscle (体力) energy. Yellow is often associated with food. Bright yellow can get more attention than other colors. That’s why taxis are painted this color. When overused, yellow may make people disturbed(不安的) ; it is known that babies cry more in yellow rooms. Yellow is seen before other colors when it is put against black; this way is often used to give a warning. In some big events, yellow represents honor (荣誉) and loyalty. Also, the meaning of yellow is connected with weakness.
People use yellow to call up pleasant, cheerful feelings. They can choose yellow to help sell children’s products (产品). Yellow is very useful for catching attention, so people can use it to highlight the most important part of a design. However, men usually think of yellow as a very joyful, childish color, so it is not recommended to use yellow when selling famous, expensive products to men. Nobody will buy a yellow business suit. Yellow is an unstable(不稳定的) color, so try not to use yellow if you want to suggest stability(稳定) and safety. Dark yellow represents warning, sickness and jealousy(嫉妒的).

（2021·江苏·南京市第十三中学九年级阶段练习）What do you think of black cats Are they unluckier than cats of other colors Many people in Western countries think so. Scientists at the University of California Berkeley (UC Berkeley) did a study on cat colours and people’s understandings of cat personalities.
The study found that people do judge (判断) cat personalities by color. Scientists did a survey on the Internet. There were 49 statements (描述) matching five cat colorings with 10 personalities. People think orange and bi-coloured (双色的) cats are friendly, tri-coloured (三色的) cats are not generous and white cats are calm, lazy and shy. As for black cats people think they don’t have special personalities.
But why do so many people dislike keeping black cats as pets People think black cats have less special personalities which might be because of their bad reputation (口碑). They think black cats may bring bad luck especially at Halloween. Movies and television shows also make people believe that.
Although people have these ideas, UC Berkeley scientists give another reason: people don’t think black cats are pretty enough. After all nothing can show black cats are unluckier than other cats. “You can’t judge a cat by its colour because it’s the personality of the cat not the colour that will let you know if the cat is right for you” Cathy Marden, a scientist said.
22．Many people in Western countries may think black cats are ________.
A．lovely animals B．a sign of bad luck

（2021·江苏·盐城市第一初级中学九年级阶段练习）I wonder whether there is any girl or boy who does not like to see a rainbow in the sky. It is so beautiful.
There is a story, saying that whenever you see a rainbow you should run at once to the place where it touches the ground, and there you would find a pot of gold. Of course it is not true. You could not find the pot of gold or its end. No matter how far you run, it always seems far away.
A rainbow is not a thing which we can feel with our hands as we can feel a flower. It is only the influence of light shining on raindrops. The raindrops catch the sunlight and break it up into all the wonderful colours which we see. It is called a rainbow perhaps because it is made up of raindrops and looks like a bow(弓).
That is why we can never see a rainbow in a clear sky. We see a rainbow only when there is rain in the air and the sun is shining brightly through the clouds.
Every rainbow has many colours in the same order. The first of the top colour is always red, next comes orange, then green, and last of all, blue. A rainbow is indeed one of the wonders of nature.
26．Children like rainbows because ________.
A．they are beautiful B．they are like bows
C．they can find a pot of gold at the end of a rainbow D．they are good to crops

29．We can see a rainbow ________.
A．when it is raining heavily B．when it is snowing
C．when it is cloudy D．when it becomes fine shortly after raining .
30．Which of the sentence is not true

C．There are seven colours in a rainbow ,the last colour is green.
D．A rainbow is one of the wonders of nature.
（2022·江苏·沭阳县怀文中学九年级期中）Many scientists find that colours can change people’s feelings.
It’s very interesting. Some colours can make people feel relaxed, and some colours can make people feel nervous. Now, this kind of knowledge is being used in many places. For example, school walls are always painted green because green makes students feel relaxed. It is also good for the students’ eyes. Some books are also green or light blue for the same reason.
Restaurant owners not only have to know how to make food, but also have to know how to make money. Here are some things they’ve learned from scientific studies. The colour red makes people hungry. Many fast food restaurants have red furniture or walls. Soft colours like pink and light blue make people feel relaxed, so they spend more time eating. Loud music may be nice at first, but it soon makes people want to leave. Hard seats also make customers want to eat quickly and leave. Many restaurants, especially fast food restaurants, use this knowledge to make customers eat faster.
31．Which colour isn’t mentioned in this passage
A．Green. B．White. C．Light blue. D．Red.
32．What do many fast food restaurants do

（2022·江苏·大港中学九年级阶段练习）
The idea that red means stop and green means go has influenced our lives in more ways than just traffic signals. We have been taught from a young age that the colour red means danger and green means it is okay to move forward. But why were those colours chosen for traffic lights in the first place For something we have to look at every day, why couldn’t they have been prettier colours
Well, it’s important to know that before traffic lights for cars, there were traffic signals for trains. At first, railway companies used red to mean stop, white to mean go, and green to mean warn. As you could imagine, trains ran into a few problems with white meaning go. For example, one train mistook a bright star for a white
light and something unexpected happened. Because of that, railway companies finally moved green meaning go and used yellow to mean warn. And it’s been that way ever since.
Red has always been a colour that meant danger, long before cars were even around. This most likely started because it’s the colour with the longest wavelength(波长) so it can be seen somewhere farther than other colours.
But, believe it or not, yellow was once used to mean stop. Back in the 1900s, some stop signs were yellow because it was too hard to see a red sign in a poorly lit area. Finally, highly reflective materials(高反射材料) were developed and red stop signs were born. Since yellow can be seen well at all times of the day, school zones, some traffic signs, and school buses continue to be painted yellow.
So next time you’re impatiently waiting at a traffic light, don’t get so mad at them; they’ve certainly come a long way.
34．Which of the following colours meant go at first
A．Red. B．Yellow. C．White. D．Green.
35．Why does red mean danger
A．Because it’s the brightest colour. B．Because it can be seen far away.
C．Because railway companies say so. D．Because it has the shortest wavelength.
36．What does the text mainly tell use
A．How important traffic lights are. B．Which colour has the longest wavelength.
C．What red, yellow and green can be used for. D．Why traffic lights are red, yellow and green.

Next time, when you get stuck(堵塞) behind a slow driver, look at the colour of his car. It will probably be green. American researchers have found that green cars are chosen by stubborn(固执的) drivers who dislike to get out of the way for anybody. They also complain about the way others drive.
The study also shows that bright red cars are usually driven by outgoing people who hate being overtaken(赶超). And, it is said that yellow cars are always in a hurry. Drivers of yellow cars will not wait when they get stuck. They will turn off the road and try to find another way.
Blue is the colour chosen by the relaxed drivers. It’s hardly possible for them to get angry with other drivers and they will almost certainly stop before the red light.
Black was the only colour available when cars were first sold. Many people remember that Henry Ford, the producer of the first cars, once said “Any colour—so long as (只要)it’s black” when someone asked about what colour car he could have. Now black has become a popular colour in some countries.

（2021·江苏·沭阳县修远中学九年级阶段练习）Mary didn’t understand such sentences as “She is blue today.”, “You are yellow.”, “He has a green thumb.”, “He has told a white lie.” and so on. And she went to the teacher Mrs James for help.
Mary: Mrs James, there is a colour in each of the sentences. What do they mean

with a green thumb grows plants well and a white lie is not a bad one.
Mary: I’m afraid I don’t understand them all. Would you give me an example for “a white lie”
Mrs James: Certainly. Now I just give you some bread. In fact you don’t like it, but you don’t want to let me know it. Instead you say, “No, thanks. I’m not hungry.” That’s a white lie.
Mary: It sounds very interesting. Thanks very much.
Mrs James: You are welcome. Colours are meaningful. I think you will meet more sentences like these in the future. Please come to me if you have any questions.

（2021·江苏·沭阳县修远中学九年级阶段练习）The world around us is full of colours—the grass is green, and the sky is blue. What a pity it will be if people can not see the colours. But there are people who are blind to certain colours.
Human colour blindness is a strange thing to explain. In a single eye there are millions of very small things called “cones”. They help us to see in bright light and to tell the difference between colours. There are also millions of “rods” which are used for seeing when it is nearly dark. They show us the shape but not the colour.
Some birds and other animals’ eyes have few or no cones, so they cannot see colours. Cats and dogs cannot see colours as well as we can.
Some insects(昆虫) can even see X－rays. Scientists know that there are other colours around us which insects can see but we cannot see.
People have their favourite colours. Blue is often popular because it is the colour of the sky and sea. Green is the colour of nature, it makes us think of grass, field and forest. Yellow is the colour of the sun. Red is the colour of blood and fire. It makes some people think of accidents, danger and blood. Black is the colour of the night. In the dark we cannot see what is around us, so we are sometimes afraid of the unknown and do not like black as a colour.
8．What does the underlined phrase “colour blindness” mean in Chinese
A．夜盲 B．色差 C．色盲 D．色弱
9．Which of the following statements about “cones” and “rods” is RIGHT
A．Some birds can’t see colours because their eyes have no rods.
B．Cones are used for seeing in the dark.
C．Rods help us to see in bright light.
D．Rods show us the shape but not the colour at night.
10．We can find this article in ________ column (栏目) of a magazine.
A．Amazing animals B．Believe it or not C．Do it yourself D．Let’s play
（2022·江苏·南通市新桥中学八年级期中）If you go shopping in any toy store, you can see clearly the different games and toys for boys and girls: there are a lot of pink toys on one side of the store for girls; and dark-coloured cars, guns, and soldiers for boys. Some big stores with toys may even have a pink floor for girls and a blue floor for boys. In fact, it is difficult to buy a toy for a girl that is not pink.
Some people think that too much pink is bad for girls. Sue Palmer, writer of Toxic Childhood, is very worried that most girls over the age of three are crazy about the colour. According to some scientists, this happens for two reasons. Firstly, most companies offer too many products in pink. Also, many parents think their little daughter looks cute in pink. Sue Palmer says that girls at this age cannot make proper decisions by themselves, but the pink can affect the choices and the decisions they will make in the future.
Some parents are worried too—for example, Vanessa Holburn, thirty-two, who has two girls under the age of four. Their bedrooms are a sea of pink and Vanessa is not happy. “Pink says that you are soft and gentle. Blue says that you are strong and powerful. I want my daughters to be strong and powerful. I’m worried that pink will not help them with that,” she says.
But not everyone thinks there’s something wrong with pink. Grayson Turner is a father of three girls and he isn’t worried at all. “People forget that things change all the time,” he says. “My girls used to love pink when they were little, but as they get older, they change.” Turner explains that his twelve-year-old daughter never wears pink clothes any more. “This love of pink is just a fashion and all fashions change,” he adds. “It’s only since the 1940s that people have started dressing girls in pink—before that it was a colour for boys.”
11．Which of the following best shows the structure of the passage
A． B． C． D．
12．According to Grayson Turner, ________.
A．parents needn’t worry about pink toys B．all little kids love the colour pink
C．pink has always been a colour for girls D．his girls now prefer the colour blue
13．The purpose of this passage is to ________.
A．explain why girls are crazy about the colour pink
B．make parents less worried about the colour pink
C．encourage girls to give up playing with pink toys
D．show people’s different opinions about the colour pink
（2021·江苏·扬州市江都区第三中学九年级阶段练习）Many daily American expressions are based on(以……为基础) colours.
Red is a hot colour. Americans often use it to represent heat. When they say “red-hot”, that means they are very angry about something. Loud music is popular with many people. Some may say that such music is red-hot.
Pink is a lighter kind of red. People sometimes say “I’m in the pink” when they are in good health. The expression was first used in America at the beginning of the 20th century. It probably comes from the fact that many babies are born with a nice pink colour that shows that they are in good health.
Blue is a cool colour. The old Blues music in the United States is the opposite of red-hot music. Blues is slow and sad. Someone who is “blue” is very sad.
The colour green is natural for trees and grass. But it is an unnatural colour for humans. A person who has an upset stomach may say “I’m feeling a bit green”. A person on a boat who is feeling very sick from high waves can be said “look very green”. Sometimes a person may be very jealous because he does not have anything as nice as someone has, like a fast new car. That person may say “I’m green with envy”. Some people are green with envy because someone has more dollars or “greenbacks”. Dollars are called greenbacks in American slangs because that is the colour of the bottom of their bank notes.
The colour black is used often in expressions. People may say “it’s a black day” when everything goes wrong on that day.
In some cases, colours describe a situation. Blackouts were common during the World War II. All the lights in a city were turned off at night to make it difficult for enemy planes to find their aims in the dark.

（2021·江苏盐城·九年级阶段练习）Yellow is the colour of sunshine. It has something to do with joy, happiness, and energy. Light yellow is also associated with (和……有关) freshness. Yellow gives us warming feelings, encourages cheerfulness and mental activity, and creates muscle (体力) energy. Yellow is often associated with food. Bright yellow can get more attention than other colors. That’s why taxis are painted this color. When overused, yellow may make people disturbed(不安的) ; it is known that babies cry more in yellow rooms. Yellow is seen before other colors when it is put against black; this way is often used to give a warning. In some big events, yellow represents honor (荣誉) and loyalty. Also, the meaning of yellow is connected with weakness.
People use yellow to call up pleasant, cheerful feelings. They can choose yellow to help sell children’s products (产品). Yellow is very useful for catching attention, so people can use it to highlight the most important part of a design. However, men usually think of yellow as a very joyful, childish color, so it is not recommended to use yellow when selling famous, expensive products to men. Nobody will buy a yellow business suit. Yellow is an unstable(不稳定的) color, so try not to use yellow if you want to suggest stability(稳定) and safety. Dark yellow represents warning, sickness and jealousy(嫉妒的).

（2021·江苏·南京市第十三中学九年级阶段练习）What do you think of black cats Are they unluckier than cats of other colors Many people in Western countries think so. Scientists at the University of California Berkeley (UC Berkeley) did a study on cat colours and people’s understandings of cat personalities.
The study found that people do judge (判断) cat personalities by color. Scientists did a survey on the Internet. There were 49 statements (描述) matching five cat colorings with 10 personalities. People think orange and bi-coloured (双色的) cats are friendly, tri-coloured (三色的) cats are not generous and white cats are calm, lazy and shy. As for black cats people think they don’t have special personalities.
But why do so many people dislike keeping black cats as pets People think black cats have less special personalities which might be because of their bad reputation (口碑). They think black cats may bring bad luck especially at Halloween. Movies and television shows also make people believe that.
Although people have these ideas, UC Berkeley scientists give another reason: people don’t think black cats are pretty enough. After all nothing can show black cats are unluckier than other cats. “You can’t judge a cat by its colour because it’s the personality of the cat not the colour that will let you know if the cat is right for you” Cathy Marden, a scientist said.
22．Many people in Western countries may think black cats are ________.
A．lovely animals B．a sign of bad luck

（2021·江苏·盐城市第一初级中学九年级阶段练习）I wonder whether there is any girl or boy who does not like to see a rainbow in the sky. It is so beautiful.
There is a story, saying that whenever you see a rainbow you should run at once to the place where it touches the ground, and there you would find a pot of gold. Of course it is not true. You could not find the pot of gold or its end. No matter how far you run, it always seems far away.
A rainbow is not a thing which we can feel with our hands as we can feel a flower. It is only the influence of light shining on raindrops. The raindrops catch the sunlight and break it up into all the wonderful colours which we see. It is called a rainbow perhaps because it is made up of raindrops and looks like a bow(弓).
That is why we can never see a rainbow in a clear sky. We see a rainbow only when there is rain in the air and the sun is shining brightly through the clouds.
Every rainbow has many colours in the same order. The first of the top colour is always red, next comes orange, then green, and last of all, blue. A rainbow is indeed one of the wonders of nature.

A．they are beautiful B．they are like bows

D．A rainbow is one of the wonders of nature.
（2022·江苏·沭阳县怀文中学九年级期中）Many scientists find that colours can change people’s feelings.
It’s very interesting. Some colours can make people feel relaxed, and some colours can make people feel nervous. Now, this kind of knowledge is being used in many places. For example, school walls are always painted green because green makes students feel relaxed. It is also good for the students’ eyes. Some books are also green or light blue for the same reason.
Restaurant owners not only have to know how to make food, but also have to know how to make money. Here are some things they’ve learned from scientific studies. The colour red makes people hungry. Many fast food restaurants have red furniture or walls. Soft colours like pink and light blue make people feel relaxed, so they spend more time eating. Loud music may be nice at first, but it soon makes people want to leave. Hard seats also make customers want to eat quickly and leave. Many restaurants, especially fast food restaurants, use this knowledge to make customers eat faster.
31．Which colour isn’t mentioned in this passage

（2022·江苏·大港中学九年级阶段练习）
The idea that red means stop and green means go has influenced our lives in more ways than just traffic signals. We have been taught from a young age that the colour red means danger and green means it is okay to move forward. But why were those colours chosen for traffic lights in the first place For something we have to look at every day, why couldn’t they have been prettier colours
Well, it’s important to know that before traffic lights for cars, there were traffic signals for trains. At first, railway companies used red to mean stop, white to mean go, and green to mean warn. As you could imagine, trains ran into a few problems with white meaning go. For example, one train mistook a bright star for a white
light and something unexpected happened. Because of that, railway companies finally moved green meaning go and used yellow to mean warn. And it’s been that way ever since.
Red has always been a colour that meant danger, long before cars were even around. This most likely started because it’s the colour with the longest wavelength(波长) so it can be seen somewhere farther than other colours.
But, believe it or not, yellow was once used to mean stop. Back in the 1900s, some stop signs were yellow because it was too hard to see a red sign in a poorly lit area. Finally, highly reflective materials(高反射材料) were developed and red stop signs were born. Since yellow can be seen well at all times of the day, school zones, some traffic signs, and school buses continue to be painted yellow.
So next time you’re impatiently waiting at a traffic light, don’t get so mad at them; they’ve certainly come a long way.
34．Which of the following colours meant go at first
A．Red. B．Yellow. C．White. D．Green.
35．Why does red mean danger
A．Because it’s the brightest colour. B．Because it can be seen far away.
C．Because railway companies say so. D．Because it has the shortest wavelength.
36．What does the text mainly tell use
A．How important traffic lights are. B．Which colour has the longest wavelength.
C．What red, yellow and green can be used for. D．Why traffic lights are red, yellow and green.
