2 . The Internet, mobile phones and iPads are parts of our lives now. Technology is greatly affecting all ways of our lives, from the ways we work to the ways we play. And it even causes a number of social problems such as cloning (克隆) humans.
We have had lots of technology and it has changed our lives a lot. There is no doubt that humans will continue to use more and more technology. Here are some examples of modern technology that will change our ideas and will affect our lives greatly.
| Global positioning system (GPS) It’s a system that uses radio signals from satellites to show exact (精确的) information. It tells you where the user is on the Earth in all weather conditions. It’s made up of three parts: satellites, control equipment (设备) on land and receivers. |
| Space technology Russian and American scientists have worked together for the International Space Station (ISS) for a long time. They hope the ISS will provide a long-lasting lab. Such a lab will bring humans limitless (无限的) advantages. It’s even hoped that one day space technology will take humans to their new houses in space. |
| Underwater robot Hercules is a kind of underwater robot with some high technology equipment. It will be used to search for ancient ships which were destroyed into the deep sea during their journey long ago. |
The world is changing so quickly that it’s hard for us to catch up with all the new inventions because they seem to come out every month. It’s important for us to learn about new technology and the role that it plays in our lives. So we should be willing to accept modern technology, or we will fall behind the times.

3 . Self-driving cars are believed to be the future of driving. Companies including Toyota, Uber and Google are all competing to be the first to bring them to market.
However, car makers need to solve one problem first: How driverless cars communicate with passers-by, bikers and other drivers. Most drivers today use gestures to show their purposes. They wave a car into a lane(车道), or nod at passers-by and cyclists, to let them cross the street. But self-driving cars don’t have this ability. What can they do? US carmaker Ford and its partner Virginia Tech think they have the answer, reported Business Insider. The team is testing a method that uses light signals to show what self-driving cars are doing. For example, if a driverless car is yielding, it could flash two white lights side to side. A solid white light tells there are no humans in the car. A slow blinking light shows the car is coming to a stop. A rapidly flashing light tells passers-by that the car is about to speed up. To test the method on real roads, the team designed a special suit that looks exactly like a car seat. When a driver wears it, it appears to people that the car is really driverless. The team then successfully got more than 1,500 hours of data after about 2,900 kilometres of “self-driving” through busy cities. The data recorded how people interacted with a driverless vehicle. Ford says they plan to share the data with 11 other companies, reported dogonews. com. The company wants to work with other carmakers to design a signaling system that would be understood by all.

7 . Nook’s arrival, Good or Bad?
Booklovers, most of them, will tell you what a pleasure it is to lend a favorite read to a friend—the novel you stayed up all night to get to the end of; the travel book that made you feel as if you yourself were on a train ride through India. For a while it seemed that e-book users were to be denied this pleasure of lending to friends. You could b

8 . 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.

10 . What is 5G? It is the fifth generation (代) of mobile network technology. These new networks are coming.
China issued commercial license (发放商用牌照) for 5G on June 6, 2019. This means that China’s Telecom (中国电信) companies have been able to offer 5G networks to mobile phone users.
Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data (数据) and the Internet. And 4G made all of these things faster. What’s special about 5G?
5G has a very short delay (延时) between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds (毫秒) to send and receive data. But 5G will reduce the delay to 1 millisecond or less. This big change will not only make our mobile Internet faster, but also deeply change our lives.
Entertainment (娱乐)
5G networks are about 100 times faster than 4G. This means you can download (下载) a movie in seconds.
Transportation
5G will also bring us safer self-driving cars. These cars can send signals (信号) to each other. 5G will allow cars to react (反应) even faster than real drivers.
Smarthomes
5G also makes the Internet of Things possible. Internet of Things is a large network that connects everything to the Internet. Smarthomes are part of it. For example, if its sensor feels the air becoming dry, a smart sprinkler (洒水器) can water your plants by itself.
