We have recently heard some interesting ways that 5G technology might change our lives in the future. 5G promises internet speeds between 50 to 100 times faster than the present 4G systems. The technology is also built to deal with many more users without slowing services down. Such improvements are sure to be popular for 5G users worldwide.

While 5G is set to start in some limited areas of the United States this year, much of the rest of the world is not expected to receive such service widely until 2023.

One project called 5G Rural First in Britain, though, is already testing this superfast technology, but not on humans. Instead, the experiment involves an unlikely group of internet users-cows. The system connects the animals to 5G in an effort to automate（自动化）the milking process.

Testing areas are set up at farms in three countries of England. The cows are fitted with 5G devices（装置）that connect to a robotic milking system. The system uses sensors（传感器）and machine learning to fully automate the process. System designers say technology takes over after a cow feels ready to be milked and walks toward an automatic gate. The device is designed to recognize each cow. It then sets machine to the right height for milking. During the process, machines give food to the cow in return.

In one of the test areas, about 50 of the farm's 180 cows are fitted with 5G smart devices and health-watching sensors. Project officials say the devices do not harm the cows and the sensors allow farmers to immediately discover any problems such as health problems.

Other technology tools powering the 5G smart farms include automated brushes that turn on when the cow touches them. Sensors also control the supply of light in the cows' living areas depending on the weather. And an automatic feeding system makes sure the animals always get enough to eat.

Nick Chrissos works on the project. He said the system can connect every cow, and every other animal on the whole farm. “That's what 5G can do for farming—really free the power that we have within this farm, everywhere around the United Kingdom, and everywhere around the world.”

1.What's Paragraph 4 mainly about?

A.How the system automates the milking process.

B.How the technology knows when to milk cows.

C.How the designers connect 5G devices to cows.

D.How the testing areas were set up in the countries.

2.According to the passage, 5G smart farms _________.

A.effect huge changes on the animals

B.improve the cow operations in many ways

C.make the internet speed slow down greatly

D.test the technology on both cows and people

3.What's Nick Chrissos' attitude towards the 5G technology?

A.Worried. B.Hopeful. C.Surprised. D.Doubtful.

Now, are you changing your living habits to have a low carbon life? Here are some strategies (策略) for you.

Strategy One

●Each week, choose one day when you don’t eat meat. Meat takes up lots of energy because it takes a long time to produce. And animals must be fed on farmed plants, which could be used to feed many more people.

Strategy Two

●Only buy the amount of food you need. When you buy food, go local rather than imported (进口的), and get fresh vegetables instead of frozen.

Strategy Three

●Make sure you keep the things such as paper and plastic bottles separate (独立) so that they can be recycled. There are places where you can recycle batteries. Make sure you find them.

Strategy Four

●Take showers rather than baths and reduce your shower time by two minutes. This will save water and give you an extra two minutes in bed.

Strategy Five

●Buses and trains are better than cars, but walking or cycling is better still. It’s also better for your health and cheaper. It can even be quicker than sitting in a car at rush hours in a busy city. For long distances, coaches are better than trains.

Strategy Six

●Try to buy good, long-lasting products even though they may cost a little more. A small screen TV is better than a big screen. Keep your electronic products one year longer than you would usually have.

1.What does the underline phrase “low carbon” in paragraph one mean?

2. According to the passage, which of the following is WRONG?

3. What’s the purpose(目的) of the passage?

It's hard to imagine life without the Internet. How greatly it has changed our lives in the past 15 years since it was widely used. At the same time, however, the Internet has also caused some traditions to fall away (消失).
