Unit 3 The world of science
一、阅读理解（本大题共15小题，共30.0分）
A
In the field of educational technology, some apps might be getting too smart. There are more and more apps providing help for students.
Photomath
The new, seemingly magic app allows users to take pictures of a math problem, and then receive a step-by-step solution. A Photomath spokeswoman says educators have welcomed the app with positive reviews, but the app causes a lot of angry public discussion and disagreement. Why It is because students can use it to cheat when doing their math homework.
Price: Free
iHomework 2
Whether you're a high school student or a college student, there's one thing you've got for sure: a lot of schoolwork. iHomework 2 can help you keep track of all your homework. It can help you arrange it in a particular order according to types, or based on deadlines (截止日期).
Price: Free
WolframAlpha
WolframAlpha is similar to Photomath, but it focuses on older students studying high levels of math. The service also produces step-by-step solutions to advanced topics, making it a popular tool for college students.
Price: 18.00
Homework Helper
Chinese Internet search company Baidu has launched an app called Homework Helper with which students can get answers to homework. Users post a picture or type their homework questions onto online forums, and those who answer the questions can win e-coins that can be used to buy some products. The app has more than 800 million users, much to the concern of many parents who argue that the students spend less time thinking about challenging problems.

Long before social distancing, Greg Dailey was already keeping his customers at arm's length. In fact, to those on his paper route in central New Jersey, Greg has never been anything more than a shape past their driveway. But all that changed when one elderly customer asked him a simple favor: Could he please pull in and throw the paper closer to the garage
"If she can't get the paper at the sidewalk, which is 20 feet from the house, during the COVID-19 pandemic (流行病), how is she going to get the things she needs " Greg said. "So a couple days later I just decided, you know what, I'm going to put this note out." The note, stuck in the next day's edition, said "My name is Greg Dailey and I deliver your newspaper every morning"—which was news to most people—"I would like to offer my services—free of charge—to anyone who needs groceries (食品杂货)."
From that moment, the phone has been ringing off the hook. He takes the orders, does the shopping, and delivers the groceries—not by throwing them out the window, but by carefully placing them on the porch.
So far, he's delivered to nearly 100 senior citizens on his route, and some not on his route. If Greg hears about a person who is elderly or disabled, he will be there. Eileen Stein, 85, said: "I don't have enough adjectives. He is one of the finest people in the world." Another went even further, and called him the closest thing to bravery and kindness.
Greg says he might not necessarily stop when the pandemic is over. "There's something about being able to do something really nice for people," Greg said. Greg didn't do volunteer work before—actually, he didn't do his own grocery shopping before. He's just a guy called on to do it by chance—who will now stay in service by choice.
4. What does the underlined part in paragraph 1 mean
A. Being familiar with his customers.
B. Being fond of his paper delivery job.
C. Trying to narrow the social distance gap.
D. Avoiding close contact with his customers.
5. Why did Greg begin the grocery delivery service
A. To earn more.
B. To make himself better known.
C. To do grocers a favor.
D. To help customers get necessities easily.
6. Which word best describes customers' attitude to Greg
A. Appreciative. B. Confused. C. Negative. D. Unconcerned.
7. What can we infer about Greg from the last paragraph
A. He will start his own grocery store.
B. He used to take part in volunteer work.
C. He developed more newspaper delivery routes.
D. He will continue his services after the pandemic.

A solar-powered car that can be charged as it drives is being tested in Germany. Munich-based producer Sono Motors has built the new type, named Sion, and will likely help the European company hit its national goal of 1 million electric cars on the road.
Sono Motors which was founded in 2016 wants to achieve great development in the electric car market. It is on its way to beginning production of one of the first affordable electric cars—the Sion.
The Sion has a total of 248 solar cells built into the vehicle, which enable the vehicle to recharge its battery when sunlight is hitting the solar cells, whether it is on the road, or parked in the sunny spot in a car park. Sono Motors has also included support for traditional power outlets (电源插座)—so car owners aren't left on cloudy days.
The Sion also uses moss (苔藓) fixed into the dashboard to naturally change the wetness inside the car. The solar panel-packed vehicle is set to put into the market in Germany before long.
Sono Motors wants the Sion to be universal and hopes to allow the car to be charged using solar energy as well as traditional outlets. Some 8,800 people have already placed orders for the electric vehicle. Prices for the Sion tend to start from ?16,000 next year. The all-electric vehicle will offer a range of up to 305 km before the battery runs out completely and it needs to recharge by either solar power or using a wall outlet, the company said.
The Sion was designed originally as an environmentally friendly car. It will also be designed around comfort to help it compete with other modern vehicles. "We have a seat heater and there is air conditioning and a large infotainment (资讯娱乐节目) system where I can also connect my phone interactively, which means I really have a vehicle which is very simple and has no decoration," Laurin Hahn, co-founder and CEO of the company told Reuters.
8. Why can the Sion continue to work even on a cloudy day
A. It has 248 solar cells working.
B. It can use traditional power outlets.
C. It can be recharged wherever it stops.
D. It stores lots of energy ahead of time.
9. Why is the moss used in the Sion
A. To decorate the car. B. To keep the air fresh.
C. To control the wetness. D. To change the temperature.
10. What can we know about the Sion from Laurin Hahn's words
A. It is nicely decorated. B. It is expected to be cheaper.
C. It has many unique functions. D. It needs to be further improved.
11. What's the best title of the text
A. The first electric cars put into the market
B. New solar-powered cars developed in Germany
C. Sono Motors contributing to environmental protection
D. The solar-powered cars taking the place of traditional cars
D
The story of moon trees started in 1971, when Apollo 14 started a task to the moon. The task pilot was Stuart Roosa, a former U. S. Forest Service smoke jumper. When he was selected for the job, a few of his Forest Service co-workers asked him to take hundreds of tree seeds (种子) into space with him. He agreed.
Seeds were collected from five types of trees: loblolly pine, sycamore, sweetgum, redwood, and Douglas fir. The seeds were sorted—there were 400-500 in total—and another set of seeds remained on Earth as a control sample (对照样本).
On Jan. 31, 1971, Roosa, along with astronauts Alan Shepard and Edgar Mitchell, took off on the third task to the moon. The seeds stayed with Roosa as he moved around the moon and flew back to Earth. But the tool containing the seeds burst open, and the crew thought the seeds couldn't germinate any longer. However, the Forest Service sent the seeds to two of their stations anyway. Nearly all of the seeds began to sprout (发芽), and after a few years, the Forest Service had more than 420 young moon trees.
In 1975 and 1976, most of the young trees were given away to be planted for the country's two hundredth celebration. Not all states received trees because the five species were from western and southern states and wouldn't grow in other climates. Other young moon trees found homes in the U. S. such as at the White House, the Kennedy Space Center in Florida, the Goddard Space Flight Center in Maryland, Washington Square in Philadelphia, Valley Forge National Historical Park in Pennsylvania, and various universities. Some trees were given away as gifts to other countries, including Brazil, Switzerland, and Japan.
The number of moon trees has increased over the years, as cuttings were taken off moon trees and replanted. These second-generation moon trees are called half-moon trees. Roosa passed away in 1994, but a moon sycamore stands over his grave in Virginia.
12. Why were a set of tree seeds left on Earth
A. To tell moon trees apart easily.
B. To ensure their growth under control.
C. To protect them against being damaged.
D. To make a comparison with seeds in space.
13. What does the underlined word "germinate" in paragraph 3 probably mean
A. Suffer. B. Grow. C. Float. D. Change.
14. What do we know about moon trees from the last paragraph
A. Their type has increased greatly.
B. They are renamed half-moon trees.
C. They don't grow very well on Earth.
D. Their cuttings lead to more moon trees.
15. What is the main idea of the text
A. The story of moon trees.
B. The discovery of moon trees.
C. The three tasks of Roosa to the moon.
D. The contribution of Roosa to moon trees' growth.

One morning, Joey sat at the kitchen table and read the sports page of the paper. He heard his grandfather coming down the stairs. When his grandfather came into the kitchen, Joey could see he wasn't his usual happy self.
"Morning, Grandfather," he smiled. His grandfather sat across the table, looking sad. He didn't pick up the paper to read. Instead, he asked, "Joey, is anything happening in town today " "There's a ball game between Sequoyah Middle School and my school tonight. Would you like to go " Joey told him.
Joey felt bad for his grandfather. He knew he couldn't read. His grandfather had told him often, "I didn't have the chance to go to school regularly. Looking after the animals and tending to the crops on the farm were much more important in those days than learning to read."
One day Grandfather asked Joey, "Joey, would you go with me to the grocery store (食品杂货店) I need several things." In the store, Joey's grandfather walked up and down the aisles (过道), looking at all the pictures on the cans. He saw a can without a picture on it. "What's in that can " he asked. Joey, reading the label, said "It's a can of chicken soup." His grandfather walked to the meat counter but he couldn't read the prices or the labels. Finally, Grandfather gave Joey the grocery list and stepped out of the store. "I will meet you at the car," he said. Joey watched him go through the door, and he thought, "I wish I could help him out but I don't know where to begin and how to start."
The next day was Sunday. Joey went to the library to look through some books when he saw a sign on the library wall. It read, "Do you know somebody who can't read We can help. Just call this number." Joey wrote the number down, and hurried home. "Somebody can teach you how to read. Just call this number," Joey explained excitedly to his grandfather.
Paragraph 1:
Several days later, Grandfather put on his best suit for his first day of school. ____________________________________________________________________

Paragraph 2:
Months later, Grandfather said to Joey, “I just got a letter from Aunt Helen and let me read it to you." ____________________________________________________________________

37.【答案】 Several days later, Grandfather put on his best suit for his first day of school. He arrived at the library an hour early. During that first class, he was so worried and nervous that he couldn't remember anything the teacher said. He felt very sad and even wanted to give up. Joey encouraged him and promised to help with his study. They learned together and worked hard on the lesson every day. He took over a lot of chores to give his grandfather more time to study. Grandfather's constant efforts earned considerable progress in the following months.
Months later, Grandfather said to Joey,“I just got a letter from Aunt Helen and let me read it to you." As Grandfather read, he pronounced each word very slowly. When he finished reading the letter, Joey cried. He was so proud of his grandfather for overcoming a lifelong obstacle that his chest felt as though it was about to burst. Grandfather looked up from the page and locked his tear-filled eyes on Joey. "Grandfather," said Joey, "good job! I'm so proud of you." Grandfather smiled back.

In the field of educational technology, some apps might be getting too smart. There are more and more apps providing help for students.
Photomath
The new, seemingly magic app allows users to take pictures of a math problem, and then receive a step-by-step solution. A Photomath spokeswoman says educators have welcomed the app with positive reviews, but the app causes a lot of angry public discussion and disagreement. Why It is because students can use it to cheat when doing their math homework.
Price: Free
iHomework 2
Whether you're a high school student or a college student, there's one thing you've got for sure: a lot of schoolwork. iHomework 2 can help you keep track of all your homework. It can help you arrange it in a particular order according to types, or based on deadlines (截止日期).
Price: Free
WolframAlpha
WolframAlpha is similar to Photomath, but it focuses on older students studying high levels of math. The service also produces step-by-step solutions to advanced topics, making it a popular tool for college students.
Price: 18.00
Homework Helper
Chinese Internet search company Baidu has launched an app called Homework Helper with which students can get answers to homework. Users post a picture or type their homework questions onto online forums, and those who answer the questions can win e-coins that can be used to buy some products. The app has more than 800 million users, much to the concern of many parents who argue that the students spend less time thinking about challenging problems.

Long before social distancing, Greg Dailey was already keeping his customers at arm's length. In fact, to those on his paper route in central New Jersey, Greg has never been anything more than a shape past their driveway. But all that changed when one elderly customer asked him a simple favor: Could he please pull in and throw the paper closer to the garage
"If she can't get the paper at the sidewalk, which is 20 feet from the house, during the COVID-19 pandemic (流行病), how is she going to get the things she needs " Greg said. "So a couple days later I just decided, you know what, I'm going to put this note out." The note, stuck in the next day's edition, said "My name is Greg Dailey and I deliver your newspaper every morning"—which was news to most people—"I would like to offer my services—free of charge—to anyone who needs groceries (食品杂货)."
From that moment, the phone has been ringing off the hook. He takes the orders, does the shopping, and delivers the groceries—not by throwing them out the window, but by carefully placing them on the porch.
So far, he's delivered to nearly 100 senior citizens on his route, and some not on his route. If Greg hears about a person who is elderly or disabled, he will be there. Eileen Stein, 85, said: "I don't have enough adjectives. He is one of the finest people in the world." Another went even further, and called him the closest thing to bravery and kindness.
Greg says he might not necessarily stop when the pandemic is over. "There's something about being able to do something really nice for people," Greg said. Greg didn't do volunteer work before—actually, he didn't do his own grocery shopping before. He's just a guy called on to do it by chance—who will now stay in service by choice.
4. What does the underlined part in paragraph 1 mean
A. Being familiar with his customers.
B. Being fond of his paper delivery job.
C. Trying to narrow the social distance gap.
D. Avoiding close contact with his customers.
5. Why did Greg begin the grocery delivery service
A. To earn more.
B. To make himself better known.
C. To do grocers a favor.
D. To help customers get necessities easily.
6. Which word best describes customers' attitude to Greg
A. Appreciative. B. Confused. C. Negative. D. Unconcerned.
7. What can we infer about Greg from the last paragraph
A. He will start his own grocery store.
B. He used to take part in volunteer work.
C. He developed more newspaper delivery routes.
D. He will continue his services after the pandemic.

A solar-powered car that can be charged as it drives is being tested in Germany. Munich-based producer Sono Motors has built the new type, named Sion, and will likely help the European company hit its national goal of 1 million electric cars on the road.
Sono Motors which was founded in 2016 wants to achieve great development in the electric car market. It is on its way to beginning production of one of the first affordable electric cars—the Sion.
The Sion has a total of 248 solar cells built into the vehicle, which enable the vehicle to recharge its battery when sunlight is hitting the solar cells, whether it is on the road, or parked in the sunny spot in a car park. Sono Motors has also included support for traditional power outlets (电源插座)—so car owners aren't left on cloudy days.
The Sion also uses moss (苔藓) fixed into the dashboard to naturally change the wetness inside the car. The solar panel-packed vehicle is set to put into the market in Germany before long.
Sono Motors wants the Sion to be universal and hopes to allow the car to be charged using solar energy as well as traditional outlets. Some 8,800 people have already placed orders for the electric vehicle. Prices for the Sion tend to start from ?16,000 next year. The all-electric vehicle will offer a range of up to 305 km before the battery runs out completely and it needs to recharge by either solar power or using a wall outlet, the company said.
The Sion was designed originally as an environmentally friendly car. It will also be designed around comfort to help it compete with other modern vehicles. "We have a seat heater and there is air conditioning and a large infotainment (资讯娱乐节目) system where I can also connect my phone interactively, which means I really have a vehicle which is very simple and has no decoration," Laurin Hahn, co-founder and CEO of the company told Reuters.
8. Why can the Sion continue to work even on a cloudy day
A. It has 248 solar cells working.
B. It can use traditional power outlets.
C. It can be recharged wherever it stops.
D. It stores lots of energy ahead of time.
9. Why is the moss used in the Sion
A. To decorate the car. B. To keep the air fresh.
C. To control the wetness. D. To change the temperature.
10. What can we know about the Sion from Laurin Hahn's words
A. It is nicely decorated. B. It is expected to be cheaper.
C. It has many unique functions. D. It needs to be further improved.
11. What's the best title of the text
A. The first electric cars put into the market
B. New solar-powered cars developed in Germany
C. Sono Motors contributing to environmental protection
D. The solar-powered cars taking the place of traditional cars
D
The story of moon trees started in 1971, when Apollo 14 started a task to the moon. The task pilot was Stuart Roosa, a former U. S. Forest Service smoke jumper. When he was selected for the job, a few of his Forest Service co-workers asked him to take hundreds of tree seeds (种子) into space with him. He agreed.
Seeds were collected from five types of trees: loblolly pine, sycamore, sweetgum, redwood, and Douglas fir. The seeds were sorted—there were 400-500 in total—and another set of seeds remained on Earth as a control sample (对照样本).
On Jan. 31, 1971, Roosa, along with astronauts Alan Shepard and Edgar Mitchell, took off on the third task to the moon. The seeds stayed with Roosa as he moved around the moon and flew back to Earth. But the tool containing the seeds burst open, and the crew thought the seeds couldn't germinate any longer. However, the Forest Service sent the seeds to two of their stations anyway. Nearly all of the seeds began to sprout (发芽), and after a few years, the Forest Service had more than 420 young moon trees.
In 1975 and 1976, most of the young trees were given away to be planted for the country's two hundredth celebration. Not all states received trees because the five species were from western and southern states and wouldn't grow in other climates. Other young moon trees found homes in the U. S. such as at the White House, the Kennedy Space Center in Florida, the Goddard Space Flight Center in Maryland, Washington Square in Philadelphia, Valley Forge National Historical Park in Pennsylvania, and various universities. Some trees were given away as gifts to other countries, including Brazil, Switzerland, and Japan.
The number of moon trees has increased over the years, as cuttings were taken off moon trees and replanted. These second-generation moon trees are called half-moon trees. Roosa passed away in 1994, but a moon sycamore stands over his grave in Virginia.
12. Why were a set of tree seeds left on Earth
A. To tell moon trees apart easily.
B. To ensure their growth under control.
C. To protect them against being damaged.
D. To make a comparison with seeds in space.
13. What does the underlined word "germinate" in paragraph 3 probably mean
A. Suffer. B. Grow. C. Float. D. Change.
14. What do we know about moon trees from the last paragraph
A. Their type has increased greatly.
B. They are renamed half-moon trees.
C. They don't grow very well on Earth.
D. Their cuttings lead to more moon trees.
15. What is the main idea of the text
A. The story of moon trees.
B. The discovery of moon trees.
C. The three tasks of Roosa to the moon.
D. The contribution of Roosa to moon trees' growth.

One morning, Joey sat at the kitchen table and read the sports page of the paper. He heard his grandfather coming down the stairs. When his grandfather came into the kitchen, Joey could see he wasn't his usual happy self.
"Morning, Grandfather," he smiled. His grandfather sat across the table, looking sad. He didn't pick up the paper to read. Instead, he asked, "Joey, is anything happening in town today " "There's a ball game between Sequoyah Middle School and my school tonight. Would you like to go " Joey told him.
Joey felt bad for his grandfather. He knew he couldn't read. His grandfather had told him often, "I didn't have the chance to go to school regularly. Looking after the animals and tending to the crops on the farm were much more important in those days than learning to read."
One day Grandfather asked Joey, "Joey, would you go with me to the grocery store (食品杂货店) I need several things." In the store, Joey's grandfather walked up and down the aisles (过道), looking at all the pictures on the cans. He saw a can without a picture on it. "What's in that can " he asked. Joey, reading the label, said "It's a can of chicken soup." His grandfather walked to the meat counter but he couldn't read the prices or the labels. Finally, Grandfather gave Joey the grocery list and stepped out of the store. "I will meet you at the car," he said. Joey watched him go through the door, and he thought, "I wish I could help him out but I don't know where to begin and how to start."
The next day was Sunday. Joey went to the library to look through some books when he saw a sign on the library wall. It read, "Do you know somebody who can't read We can help. Just call this number." Joey wrote the number down, and hurried home. "Somebody can teach you how to read. Just call this number," Joey explained excitedly to his grandfather.

37.【答案】 Several days later, Grandfather put on his best suit for his first day of school. He arrived at the library an hour early. During that first class, he was so worried and nervous that he couldn't remember anything the teacher said. He felt very sad and even wanted to give up. Joey encouraged him and promised to help with his study. They learned together and worked hard on the lesson every day. He took over a lot of chores to give his grandfather more time to study. Grandfather's constant efforts earned considerable progress in the following months.
Months later, Grandfather said to Joey,“I just got a letter from Aunt Helen and let me read it to you." As Grandfather read, he pronounced each word very slowly. When he finished reading the letter, Joey cried. He was so proud of his grandfather for overcoming a lifelong obstacle that his chest felt as though it was about to burst. Grandfather looked up from the page and locked his tear-filled eyes on Joey. "Grandfather," said Joey, "good job! I'm so proud of you." Grandfather smiled back.
