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.

We all have habits that we want to give up. These are habits which are not good for us in some way or another. A habit is an activity that we have got used to. It's not easy to break a bad habit because we have got used to it, and it has become convenient (方便的).

We are so used to our bad habits that most of the time we even don't realize that we have them until someone points them out to us. So the first step that will lead to changing a bad habit is to accept the fact that is not good for you.

Since you know you have developed a bad habit, it's best to find out why you developed it in the first place. Find out the reason behind it, as that will help you in understanding why you're so willing to perform that act. There is nothing to feel scared of. You have to face it and then give it up.

Find out how bad habits have spoiled (损坏，糟蹋) things around you. For example, a bad habit of getting up late can destroy the schedule (时间表) of your whole day. And, if this is what you do every day, then imagine how many days it has already eaten up. Realize this and make up your mind to give it up.

An alarm (警报) is something that will prevent you from performing your habit. For example, to avoid getting up late, set an alarm and decide that you need to make a little effort to reach it to turn it off.

Tell your family and friends about your decision so that they can prevent you from performing the bad habit and also remind you of the promise you made to yourself.

Reward yourself every time you stop yourself from performing the bad habit. This will keep you encouraged to break the bad habit and at the same time make you happy.

There are habits that people have carried with them for years and it will surely take some time to give them up. However, breaking a habit is a better choice than letting it grow into an addiction(瘾). Try giving up a bad habit, and feel the difference in yourself. You will be proud of yourself and I will certainly congratulate you on it.
