Unit 7 The unknown world单元话题阅读理解
一、阅读理解
Why is it called Mars (火星) Well, Mars is the name of the Roman god of war (罗马战神) . People see the planet (星球) as a symbol of war for thousands of years. It is also known as the Red Planet because of its color. It is red because it's rich in iron (铁). Chinese people called it the "fire star" for the same reason.
Scientists was interested in the planet. They first saw Mars in the sky more than 4, 000 years ago. Then, people from all over the world studied the planet. About 200 years ago, scientists started to study pieces of Mars. They broke away and drifted (漂流) through space for millions of years before they got to Earth.
Scientists have learned some things about Mars. For example, Mars is home to a 21-kilometer-tall mountain—the tallest in our solar system (太阳系) . However, Qomolangma, Earth's highest mountain, is just 9 kilometers tall. Like Earth, Mars has moons. It has two moons named Phobos and Deimos. The Red Planet also has the largest dust storms (沙尘暴) in the solar system. And they can last for months.
Earth is 10 times heavier than Mars. So The Red Planet's gravity (重力) is only 37 percent as strong as Earth's, meaning you can jump nearly two times higher on Mars. For the same reason, you are two times heavier on Earth than on Mars.
1．Why does Mars get the name "fire star"
A．Because it is red.
B．Because it is rich in iron.
C．Because it is the symbol of war.
2．When did scientists see Mars for the first time
A．Millions of years ago.
B．Over 4, 000 years ago.
C．More than 200 years ago.
3．What does the underlined word "They" refer to in paragraph 2
A．Scientists. B．Pieces of Mars. C．Stars.
4．We can know ________ about Mars in paragraph 3.
A．the color B．the weather C．the size
5．What can we infer (推断)from the last paragraph
A．Mars has stronger gravity than Earth.
B．People are heavier on Mars than on Earth.
C．People can jump higher on Mars than on Earth.

As space science develops, man has learned more and more about space. Space is not only amazing but also dangerous. While working in space, spacemen are facing danger as well as success.
Scientists have found out that the radiation (辐射) is the greatest danger to spacemen in space. When spacemen are working in space, they are in danger of the radiation from the sun and other stars, which is bad for their health.
The harm of the radiation won't be found until their children even grandchildren are born. Some special medicine may work a little, but no really effective medicine has been found so far.
Space rubbish is also thought to be a great danger to spacemen. It's reported that there were 9,000 man-made things flying in space. About 30% of these are satellites, 10% are spaceships, and the rest are space rubbish. An explosion (爆炸) in space in 1999 made a cloud of 300, 000 fragment (碎片), each at least 4mm in size. A small piece of these even knocked a spaceship window and caused some damage (损坏).
Scientists are watching and reporting any possible danger all the time. They are working to deal with space rubbish. Although space is really dangerous, it interests many people on the earth.
We may even choose to leave the earth and live in space in a few years. So we should do something to help improve the space environment.
6．The radiation from the sun and other stars is ________.
A．good B．helpful C．useful D．harmful
7．Space rubbish and radiation in space are dangerous to ________.
A．spacemen working in space B．people only on the earth
C．all the people except children D．the old people on the earth
8．The passage talks about ________ kinds of danger in space.
A．two B．three C．four D．five
9．Which of the following is TRUE
A．Scientists have found out ways to solve any problem in space.
B．Every one of us can have a travel to space in ten years.
C．The harm of the radiation may be found in the spacemen's children.
D．Space is really dangerous, so it doesn't interest anyone on the earth.
10．The best title (标题) of the passage is ________.
A．Space Radiation B．Space Danger
C．Space Junk D．Space Travel

On April 2, we said goodbye to Tiangong-1, China's first prototype space station. According to the China Manned Space Agency (中国载人航天局), Tiangong-1 re-entered the Earth's atmosphere (大气层) and some of its debris (碎片) fell into the South Pacific Ocean.
There are many spacecraft (宇宙飞船) that are still in orbit (轨道) above the Earth. After finishing their trips, they will all re-enter the Earth's atmosphere like Tiangong-1. There are two types of re-entries: controlled re-entry and uncontrolled re-entry.
Some satellites and manned spacecraft come back to the Earth in a controlled re-entry. Experts calculate (计算) the path of the falling spacecraft and its speed. They can guide the spacecraft to fall in a chosen area.
Some spacecraft may have problems while in space after a certain amount of time. These spacecraft come back in an uncontrolled re-entry. It is hard to tell when and where these spacecraft will fall until the last few hours. The US space station Skylab came back partially uncontrolled in 1979. Parts of the station fell in western Australia, but no one was hurt.
During re-entry, most of the spacecraft will burn up while passing through the Earth's atmosphere. Only a small amount of the debris will reach the ground. The debris typically ends up falling into the ocean, China Daily reported.
（1）The debris from Tiangong-1________.
A．fell into the South Pacific Ocean
B．fell in western Australia
C．fell in the central part of the US
D．fell into the North Pacific Ocean
（2）When the spacecraft finishes its trip, it will________.
A．burn up and disappear
B．speed up and fly back to the Earth
C．enter another orbit and stay in space
D．re-enter the Earth's atmosphere
（3）From the passage, we know there are________ types of re-entries.
A．one B．two C．three D．four
（4）Which of the following is TRUE about the US space station Skylab
A．It came back in a controlled re-entry.
B．Some people were hurt by its debris.
C．Parts of it fell in western Australia.
D．It was directed to fall into the ocean.
（5）This passage most probably comes from________.
A．a storybook B．a movie review
C．a science magazine D．a government report

"Volunteering makes you look at the world differently. You see how little things can change a person's life for the better, which makes everyone a better person," Mason, a volunteer said.
National Volunteer Week started in 1974 and is held every April. It is a time to thank volunteers for their achievements. It is also a perfect opportunity (机会) to encourage others to take their first step toward becoming a volunteer. Making the decision to take the first step can be the biggest problem, because they often wonder if they will be able to meet the organization's expectations (期望). Some people fear not knowing anyone else in the group. Not having enough time also prevents some from sharing their abilities.
The following tips can help if you have some of these worries.
Start out slowly, and don't add too much pressure. Even a few hours a month can make a big difference in someone's life.
Choose an organization with the same interests and common values.
Take part in a training meeting for new volunteers, even if it is not asked.
Work with a veteran volunteer. He volunteered a lot, and he can help you increase the confidence and completely understand the organization's expectations.
Invite a friend or family member to serve. It is a good experience to volunteer with them.
Finally, it is most important to enjoy the volunteer experience and to remember that not all volunteer experiences are perfect. If one experience doesn't work, don't give up and you'll surely find the right opportunity.
Spend some time on volunteer work and you will see great changes in people's lives. As Mason discovered during his volunteer experience, "...little things can change a person's life."
（1）Volunteering can help____________.
A．make a decision B．see the world clearly
C．thank other people D．make a person's life better
（2）What could be the reason for stopping people from taking the first step
A．They don't have enough time.
B．They are prevented by their families.
C．They fear that their abilities are shared.
D．They don't expect to become volunteers.
（3）Which of the following can help people take the first step
A．Start out quickly.
B．Organize a training meeting.
C．Invite a friend to be with them.
D．Join a group with different values.
（4）The underlined word "veteran" in the passage means "_____________".
A．polite B．humorous C．young D．experienced
（5）What is the main idea of the passage
A．To tell people to make changes in their lives.
B．To encourage people to start their volunteering.
C．How to make great achievements in volunteering.
D．How to keep on volunteering whatever happened.

Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk (垃圾) has become a problem in outer space too.
According to BBC News, there are more than 22,000 pieces of space junk floating around the Earth. And these are just the things that we can see from the surface of the Earth by telescopes (望远镜). There are also millions of smaller pieces of junk that we can't see.
Objects, like bits of old space rockets or satellites, move around the planet at very high speed, so fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle.
To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when an American satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.
To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the Earth's atmosphere after that time. In the upper parts of the atmosphere, it will burn up.
Many scientists are also suggesting different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the Earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to the Earth to be safely destroyed.
"The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers," says Marco Castronuovo, an Italian space researcher.
"The time to act is now. The longer we leave the problem, the bigger it will become," he says.
（1）What does the underlined word "these" in Paragraph 2 refer to
A．Telescopes. B．Satellites.
C．Pieces of space junk. D．BBC News reports.
（2）Why is space junk considered a problem
A．Because it burns up after it re-enters the atmosphere.
B．Because it often stops the view of telescopes on Earth.
C．Because it could force new space tools to travel at slower speeds.
D．Because it may crash into other space tools, causing damage or death.
（3）Countries want future space tools to be able to fall back into the Earth's atmosphere so that_________.
A．the tools can be reused later
B．the tools don't become space junk
C．the Earth's atmosphere can stay clean
D．the effects of space flight can be studied
（4）How do the Germans plan to deal with space junk
A．Catch it with nets.
B．Use robots to collect it.
C．Burn it in the Earth's atmosphere.
D．Send it further away from the Earth.
（5）In which section of the newspaper would you probably read this article
A．The environment. B．Local News.
C．Education. D．Fashion.

Unit 7 The unknown world单元话题阅读理解
一、阅读理解
Why is it called Mars (火星) Well, Mars is the name of the Roman god of war (罗马战神) . People see the planet (星球) as a symbol of war for thousands of years. It is also known as the Red Planet because of its color. It is red because it's rich in iron (铁). Chinese people called it the "fire star" for the same reason.
Scientists was interested in the planet. They first saw Mars in the sky more than 4, 000 years ago. Then, people from all over the world studied the planet. About 200 years ago, scientists started to study pieces of Mars. They broke away and drifted (漂流) through space for millions of years before they got to Earth.
Scientists have learned some things about Mars. For example, Mars is home to a 21-kilometer-tall mountain—the tallest in our solar system (太阳系) . However, Qomolangma, Earth's highest mountain, is just 9 kilometers tall. Like Earth, Mars has moons. It has two moons named Phobos and Deimos. The Red Planet also has the largest dust storms (沙尘暴) in the solar system. And they can last for months.
Earth is 10 times heavier than Mars. So The Red Planet's gravity (重力) is only 37 percent as strong as Earth's, meaning you can jump nearly two times higher on Mars. For the same reason, you are two times heavier on Earth than on Mars.
1．Why does Mars get the name "fire star"
A．Because it is red.
B．Because it is rich in iron.
C．Because it is the symbol of war.
2．When did scientists see Mars for the first time
A．Millions of years ago.
B．Over 4, 000 years ago.
C．More than 200 years ago.
3．What does the underlined word "They" refer to in paragraph 2
A．Scientists. B．Pieces of Mars. C．Stars.
4．We can know ________ about Mars in paragraph 3.
A．the color B．the weather C．the size
5．What can we infer (推断)from the last paragraph
A．Mars has stronger gravity than Earth.
B．People are heavier on Mars than on Earth.
C．People can jump higher on Mars than on Earth.

As space science develops, man has learned more and more about space. Space is not only amazing but also dangerous. While working in space, spacemen are facing danger as well as success.
Scientists have found out that the radiation (辐射) is the greatest danger to spacemen in space. When spacemen are working in space, they are in danger of the radiation from the sun and other stars, which is bad for their health.
The harm of the radiation won't be found until their children even grandchildren are born. Some special medicine may work a little, but no really effective medicine has been found so far.
Space rubbish is also thought to be a great danger to spacemen. It's reported that there were 9,000 man-made things flying in space. About 30% of these are satellites, 10% are spaceships, and the rest are space rubbish. An explosion (爆炸) in space in 1999 made a cloud of 300, 000 fragment (碎片), each at least 4mm in size. A small piece of these even knocked a spaceship window and caused some damage (损坏).
Scientists are watching and reporting any possible danger all the time. They are working to deal with space rubbish. Although space is really dangerous, it interests many people on the earth.
We may even choose to leave the earth and live in space in a few years. So we should do something to help improve the space environment.
6．The radiation from the sun and other stars is ________.
A．good B．helpful C．useful D．harmful
7．Space rubbish and radiation in space are dangerous to ________.
A．spacemen working in space B．people only on the earth

On April 2, we said goodbye to Tiangong-1, China's first prototype space station. According to the China Manned Space Agency (中国载人航天局), Tiangong-1 re-entered the Earth's atmosphere (大气层) and some of its debris (碎片) fell into the South Pacific Ocean.
There are many spacecraft (宇宙飞船) that are still in orbit (轨道) above the Earth. After finishing their trips, they will all re-enter the Earth's atmosphere like Tiangong-1. There are two types of re-entries: controlled re-entry and uncontrolled re-entry.
Some satellites and manned spacecraft come back to the Earth in a controlled re-entry. Experts calculate (计算) the path of the falling spacecraft and its speed. They can guide the spacecraft to fall in a chosen area.
Some spacecraft may have problems while in space after a certain amount of time. These spacecraft come back in an uncontrolled re-entry. It is hard to tell when and where these spacecraft will fall until the last few hours. The US space station Skylab came back partially uncontrolled in 1979. Parts of the station fell in western Australia, but no one was hurt.
During re-entry, most of the spacecraft will burn up while passing through the Earth's atmosphere. Only a small amount of the debris will reach the ground. The debris typically ends up falling into the ocean, China Daily reported.
（1）The debris from Tiangong-1________.
A．fell into the South Pacific Ocean
B．fell in western Australia
C．fell in the central part of the US
D．fell into the North Pacific Ocean
（2）When the spacecraft finishes its trip, it will________.
A．burn up and disappear
B．speed up and fly back to the Earth
C．enter another orbit and stay in space
D．re-enter the Earth's atmosphere

A．one B．two C．three D．four
（4）Which of the following is TRUE about the US space station Skylab
A．It came back in a controlled re-entry.
B．Some people were hurt by its debris.

"Volunteering makes you look at the world differently. You see how little things can change a person's life for the better, which makes everyone a better person," Mason, a volunteer said.
National Volunteer Week started in 1974 and is held every April. It is a time to thank volunteers for their achievements. It is also a perfect opportunity (机会) to encourage others to take their first step toward becoming a volunteer. Making the decision to take the first step can be the biggest problem, because they often wonder if they will be able to meet the organization's expectations (期望). Some people fear not knowing anyone else in the group. Not having enough time also prevents some from sharing their abilities.
The following tips can help if you have some of these worries.
Start out slowly, and don't add too much pressure. Even a few hours a month can make a big difference in someone's life.
Choose an organization with the same interests and common values.
Take part in a training meeting for new volunteers, even if it is not asked.
Work with a veteran volunteer. He volunteered a lot, and he can help you increase the confidence and completely understand the organization's expectations.
Invite a friend or family member to serve. It is a good experience to volunteer with them.
Finally, it is most important to enjoy the volunteer experience and to remember that not all volunteer experiences are perfect. If one experience doesn't work, don't give up and you'll surely find the right opportunity.
Spend some time on volunteer work and you will see great changes in people's lives. As Mason discovered during his volunteer experience, "...little things can change a person's life."
（1）Volunteering can help____________.
A．make a decision B．see the world clearly
C．thank other people D．make a person's life better

Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk (垃圾) has become a problem in outer space too.
According to BBC News, there are more than 22,000 pieces of space junk floating around the Earth. And these are just the things that we can see from the surface of the Earth by telescopes (望远镜). There are also millions of smaller pieces of junk that we can't see.
Objects, like bits of old space rockets or satellites, move around the planet at very high speed, so fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle.
To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when an American satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.
To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the Earth's atmosphere after that time. In the upper parts of the atmosphere, it will burn up.
Many scientists are also suggesting different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the Earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to the Earth to be safely destroyed.
"The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers," says Marco Castronuovo, an Italian space researcher.
"The time to act is now. The longer we leave the problem, the bigger it will become," he says.
（1）What does the underlined word "these" in Paragraph 2 refer to
A．Telescopes. B．Satellites.
C．Pieces of space junk. D．BBC News reports.
（2）Why is space junk considered a problem
A．Because it burns up after it re-enters the atmosphere.
B．Because it often stops the view of telescopes on Earth.
C．Because it could force new space tools to travel at slower speeds.
D．Because it may crash into other space tools, causing damage or death.
（3）Countries want future space tools to be able to fall back into the Earth's atmosphere so that_________.
A．the tools can be reused later
B．the tools don't become space junk
C．the Earth's atmosphere can stay clean
D．the effects of space flight can be studied
（4）How do the Germans plan to deal with space junk
A．Catch it with nets.
B．Use robots to collect it.
C．Burn it in the Earth's atmosphere.
D．Send it further away from the Earth.
（5）In which section of the newspaper would you probably read this article
