文章大意:本文主要介绍了火星上古老的淡水湖。

1 . Researchers said they had found out that there was once an ancient fresh water lake on Mars that might have been able to support life.

A team of researchers from the US Curiosity Rover Mission, analyzed (分析) some mudstone and fine-grained sediment (细粒沉积物) which can tell us that there was at least one lake around 3.6 billion years ago.

The team said their analysis showed that the lake was calm and likely had fresh water, including key biological elements, such as carbon, hydrogen, oxygen, nitrogen and sulphur (硫磺). Theoretically, such a lake would provide perfect conditions for simple living things.

The findings were published in the US Journal Science and presented at the American Geophysical Union’s fall meeting in San Francisco. “It is important to note that we have not found signs of ancient life on Mars. What we have found is that there once existed a lake on its surface which might make it possible for some simple living things to live billions of years ago,” Professor Sanjeev Gupta said in a statement. Gupta described the new research as “a huge positive step” for the exploration of Mars.

In previous studies, scientists found evidence of water on Mars’ surface in other rocks. However, the new research provides the strongest evidence yet that Mars could have been habitable enough for life to continue.

1. Researchers have found evidence that an ancient fresh water lake probably existed on ________.
A.the EarthB.VenusC.MarsD.the Moon
2. The following biological elements EXCEPT ________ have been found on Mars according to the analysis.
A.oxygenB.nitrogenC.hydrogenD.carbon dioxide
3. The underlined word “habitable” in the last paragraph probably means “________” in Chinese.
A.可居住的B.无法生存的C.习惯的D.不可能的
4. Which of the following is TRUE according to the passage?
A.The researchers thought it impossible for a fresh water lake to exist on Mars.
B.Gupta thought of the new research as “a huge positive step” for the exploration of Mars.
C.Researchers have taken great efforts to find signs of ancient life on Mars.
D.The findings about the fresh water lake haven’t been published in the US Journal Science.
5. On which column of a book can you find this passage?
A.Science.B.Travelling.C.Life.D.Education.
6. What is the passage mainly about?
A.How did the fresh water lake disappear on Mars?B.Ancient life signs found on Mars.
C.An ancient fresh water lake on Mars.D.The importance of water.

6 . It's reported that a Chinese company has created a new facial recognition system that can identify (识别) people even if they are wearing masks. Developers began working on the new system in January 2020 when the novel coronavirus appeared in China. The fast spread of the virus has led most people to wear masks in public to protect themselves and people around.

China is regarded as a world leader in the development of artificial intelligence (AI). According to engineers at the Beijing-based Hanwang Technology Ltd, this system is the first to be created to identify people wearing face masks. A team of 20 engineers completed it in about a month, adding a collection of about 6 million unmasked faces and a smaller collection of masked faces," the company said.

Hanwang is now selling two main kinds of products using the new technology. One performs single channel recognition (单通道识别), which will be used at the entrances to buildings. The other product is a multi-channel (多通道识别) recognition system that uses groups of cameras. It's said that the multi-channel system can identify a person in a crowd of up to 30 people within a second.

When people wear a mask, the recognition rate   can reach about 95 percent," said Huang Lei, Hanwang's vice president. The system's success rate for people without wearing a mask is about 99. 5 percent."

Nowadays the new system is trying to identify people with both sunglasses and a mask. In such cases, all of the key facial information is lost, making recognition hard," Huang said.

1. What does Paragraph 1 mainly want to tell us?
A.The truth that people should wear masks in public.
B.The reason why a new facial recognition system was created.
C.The time when the novel coronavirus appeared in China.
2. How is the facial recognition system able to recognize masked faces?
A.After many unmasked and masked faces are stored in it.
B.After just a large collection of masked faces are added to it.
C.After 20 engineers work hard for a month.
3. What do we know about the multi—channel recognition system?
A.It can identify people with sunglasses and masks.
B.It can be found at the entrances to buildings.
C.Many cameras are used at the same time.
4. Which part of the head does the system mainly pay attention to when a person wears a mask?
A.The hair.B.The ears.C.The eyes.
5. The writer wrote the passage to________.
A.show the rapid development of China
B.explain the popularity of AI
C.introduce a new recognition system

8 . What's going to happen in the future

What's going to happen in the future?Here are some things that scientists say is most likely to happen 10to 30 years from now.

1 Digital money

We used to pay with cash for everything we bought. In fact,we are already using one type of digital money,when we swipe(刷卡)our bus pass or use a credit card to shop online.

You have to admit that using a card is much easier than searching your pocket for change. It is also safer than carrying a lot of cash on your person. People in Sweden completely stopped using cash last year and the US might be next.

2 Bionic(仿生的)eye

People who are blind may have a chance to get their sight back-by wearing bionic eyes. A blind eye can no longer sense light,but a bionic eye can use a camera to “see” the environment and send data into the brain.

Although the bionic eye that's out now only allow patients to see lights and unclear shapes,a high resolution(分辨率)version could be just a few years away.

3 Self-driving car

Unlike a human driver,a self-driving car won't be distracted(分神)by a phone call,the radio or something outside the window. Sensors(探测器)and cameras on the car would allow it to keep strictly to the rules of the road and keep a safe distance from other cars. This would greatly reduce the number of road accidents Many vehicle companies are now planning self-driving cars. By 2040,driverless vehicles will be the main vehicles on the road.

9 . Do you find it difficult to put down your mobile phone?
If yes, you’re not alone. These days, many people are facing the stress in the use of mobile phones. They reach for their mobile phones when they wake up in the morning, and keep checking their social media apps to get the latest updates (更新).
A report from Google shows that 70 percent of people don’t want to spend much time on their phones. This is why Google introduced an app called Dashboard for the new Android operating system(安卓操作系统). This new app includes functions (功能) that help users manage the time. For example, users can see how many times they’ve unlocked their phone, how many times they’ve checked their social media apps, and how much time they spend on each app every day.
Once the users see this information, they’ll be able to make some changes. With the App Timer (计时) function, users can set a time limit for how long they can use each app for every day. After they’ve hit the limit, they won’t be able to use the app until the next day. And with another function, the app gets incoming calls silent when the user puts the phone face down.
If people truly want to make full use of their free time instead of losing hours on their phones, these new functions are just one way of doing that.
After all, who needs to use an app to stop you from using other apps? The easiest answer would be just to use your willpower.
1. Where does the users’ stress come from?
A.Too many updates of the apps.B.Too many functions of the apps.
C.Too much information they receive.D.Too much time they spend on the phone.
2. Which of the followings is NOT included in Dashboard’s functions?
A.It stops the users from using willpower.
B.It checks how much time the users spend on apps.
C.It lists how many times the users have unlocked the phone.
D.It shows how many times the users have checked social media apps.
3. What does the underlined word “limit” in Paragraph 4 mean?
A.目的B.标准C.许可D.限制
4. Which picture shows the phone gets incoming calls silent?
A.B.C.D.
5. What does the writer think of Dashboard?
A.Its design is perfect.B.It may be helpful to some people.
C.It needs more functions.D.It has too many functions.

10 . We’ve come a long way from blackboards and chalk. Modern technology (技术) has provided us with lots of ways we can make learning more interesting.   Perhaps most importantly of all, it’s also more interactive (互动).
Some kinds of tools (工具) have been developed. They make the 21st century learning experience much more interactive and interesting. Attracting the attention of students is always difficult, but these tools have made a big difference in how pupils learn.
For example, an interactive whiteboard is different from a traditional chalkboard. It allows the teachers to show images and provide sound as well.   If you imagine a large computer screen with colorful images and sound added in, you can see why so many pupils are drawn in by what they see and hear in a modern classroom.
Various audio (声音的) tools also help to make sure that everyone can hear what the teacher has to say. In the past, if a teacher said something that a child missed, perhaps the child was too timid (胆小的) or nervous to ask them to repeat it. Now they are less likely to miss out simply because they’re sitting too far away from the teacher to hear them.
The 21st century classroom is able to teach pupils more than one thing. For example, imagine a history lesson is given in a modern classroom. How is it different from a classroom setting in the past? The answer is simple. The students will not only learn about history itself, they will also learn how to use the modern equipment (设备) that helps the teacher get their message across.
Modern technology can make teaching and learning easier. Student response (应答) system makes everyone able to express their opinions or answers without having to speak up. Since everyone can do it, the teacher can see who needs more help in other ways.
It’s clear that this kind of classroom technology is making a great difference in modern classrooms.
TopicModern technology helps us make teaching and learning more interesting and interactive.
    1    
of using modern technology in the classroom
1. Make it much easier to attract pupils’     2     by using different tools.
●Whiteboards allow teachers to show colorful images and provide sound.
●Audio tools make students hear the teacher’s     3     even if they sit too far away from the teacher.
2. Make students learn more than one thing.
●Help students learn the knowledge of a       4     and the use of modern equipment as well.
3. Make teaching and learning easier.
●Student response system makes students give their opinions or answers without     5     up and allows teachers to help students when necessary.
ConclusionModern classroom technology makes a great difference to teaching and learning.
