Wang Mengshu, an expert at the Chinese Academy of Engineering, said at a group discussion of the annual session of the National People’s Congress that WiFi should not be provided on high-speed trains, as it might harm communication signals (信号) of trains and would also cost a lot in keeping trains in good condition. He also encouraged passengers to enjoy the views, instead of fixing their eyes on the tiny screens of smartphones and laptops. However,Beijing Youth Dailysaid it should be market demand that decides whether the WiFi is offered on the trains or not.
An increasing number of people, especially young white-collar workers, are addicted to their smartphones rather than face-to-face communications, thanks to the extensive WiFi coverage across the country. ThatjustifiesWang’s disagreement to the offering of WiFi on high-speed trains, because they shouldn’t depend on high-tech devices. It is also obvious that passengers on trains without free WiFi will use their smartphones and other mobile devices less. However, whether the trains should provide a free WiFi service mainly depends on customer demand.
In other words, the China Railway Corp has to obey relevant market rules, and provide technologically possible services to passengers if that is what they want. It cannot turn a blind eye to customers’ wants.
Free WiFi, in fact, is already offered on a lot of buses and coaches. This is a natural response to their competition with trains (especially high-speed ones), which are significantly faster and safer. The bus companies have been forced to improve their services to survive. So it requires proper guidance, not total “no” on the use, to make up for the negative effects of high-end technologies, such as people’s increasing addiction to smartphones.

【推荐1】With the extensive growth of crops, the requirement of modern techniques has become necessary. Here are some modern technology used in agriculture for enhancing productivity:
Information Technology in Agriculture
The most important contribution of Information Technology has been the weather forecast reports. It has helped the farmers be better prepared and gives them a heads-up if any heavy rainfall is to occur in the near time. It also gathers information and keeps track of the market prices, seasonal changes, cultivation tricks and so on.
Data Accumulated From Soil
For farmers to make informed decisions, it is necessary to understand the nature of the soil. Thus, to understand the land and to analyze its future productivity, the farmers need to learn more about the past and present state of the land. For this, the soil data is accumulated, and soil maps are prepared, to provide access to various farmers and agriculturists to study the soil capacity so that sustainable agriculture can be initiated.
Minochromosol Technology
The concept of Minochromosol Technology is very much similar to the workings of a cell. There are numerous particles inside a cell, one of which is a chromosome. It is responsible for genetic development in our bodies and it holds a lot of significance. They decide the traits in our bodies. Minochromosol Technology takes the help of chromosomes. With the help of this, many farmers can yield great profits and has helped save crops from getting infected or deficient.
Sensors- Soil and Water
Soil and Water sensors are an economical option for farmers who cannot afford highly equipped and costly technological advancements. These low-cost sensors help detect the nitrogen level and moisture content in the soil and crops. It helps the farmers to plan and schedule their crops’ water requirements.
1. In what aspect does Information Technology benefit agriculture most?A.Providing farmers with a heads-up about the market price. |

【推荐3】The discussion on renewable energy has been going on for at least a decade and people have relied on fossil fuels almost entirely for more than a century. However, the situation when fossil fuels were the most efficient and the cheapest source of energy has been left far in the past. Many countries such as Germany and Sweden have already made significant efforts to fix this situation, employing numerous power plants working on the renewable resources of energy. The most effective among these resources is geothermal (地热的) energy.
Geothermal energy does not depend on the world’s economic and political situation as strongly as fossil fuels do. Besides, extracting (提炼) fossil fuels adds to the price of energy produced from them. Therefore, geothermal energy is much cheaper than traditional ones, saving up to 80% of the costs over fossil fuels.
Being a renewable resource, geothermal energy produces less waste and pollution than traditional energy sources. In geothermal systems, carbon dioxide makes up about 10% of air produced. Overall, in order to produce the electricity that can be used for one hour, the geothermal systems produce 0.1 pound of carbon dioxide and other harmful gases. For a comparison, a power plant producing from gas produces up to 2 pounds of carbon dioxide into the atmosphere, and those power plants that work on coal (煤) produce an astonishing 3.6 pounds of greenhouse gases.
Low costs is another reason why using geothermal power plants should be the first choice for many countries. Geothermal heat systems require 25% to 50% less energy for work compared with the traditional systems for heating or cooling. Besides, geothermal equipment is less big: due to the very nature of geothermal energy, geothermal power plants have only a few moving parts, all of which can be easily sheltered inside a relatively small building. What’s more, the life span of geothermal equipment is rather long. All these make geothermal power stations easy to build and keep.

【推荐1】When faced with the decision to get out of bed or have a few more minutes of sleep, which do you choose? Believe it or not, that decision could make a world of difference in the rest of your day.
About 85 percent of Americans use an alarm clock to wake up in the mornings, according to sleep researcher Till Roen. And while there are no official numbers on snoozing(打盹), a quick survey of social media makes it clear that hitting the snooze button is a popular pastime(消遣).
As to how the snooze button will affect your day, scientists have mixed opinions. Some scientists think people who hit the snooze button in the mornings are actually clever, creative and happy while some said that hitting the snooze button will ruin your life, or at the very least your day. “I feel that hitting the snooze button has got to be one of the worst things that ever happened to human sleep,” researcher Jonathan Horowitz said. “The chances of you ‘snoozing’ and actually experiencing a meaningful rest are close to zero.”
According to some sleep experts, when hitting the snooze button, you are in fact confusing your body and mind, and throwing yourself into a deep state of being sleepy. The body needs some time to wake up. Therefore, when returning to what will be a light sleep for a brief period of time, you are putting your body back into a sleep mode before waking it again. At that point your body won’t know what it wants, resulting in a sort of half awaken state.
If you really want to take advantage of an alarm clock, the key is to form a healthy sleep cycle. Focus your efforts on getting enough sleep each night and waking up at the same time each day so that when your alarm goes off you feel rested.
1. What can we infer about hitting the snooze button from Paragraph 2?A.People do it just for fun. | B.It is a common practice. |
C.People take it seriously. | D.It is a bit childish. |
A.It is meaningful in the long term. | B.It makes people become lazy. |
C.It brings us a sense of satisfaction. | D.It affects our body and mind. |
A.Making use of willpower. | B.Trying to relax ourselves. |
C.Developing a good sleep habit. | D.Using an extra alarm. |
A.To introduce ways to keep refreshed in the morning. |
B.To explain the relationship between the snooze button and people’s character. |
C.To discuss whether people should hit the snooze button. |
D.To illustrate how to avoid the light sleep mode. |
【推荐2】Waste can be seen everywhere in the school.Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom.They say they can afford these things.But I don't agree with them.
Waste can bring a lot of problems.Although China is rich in some resources, we are short of others,for example,fresh water. It is reported that we will have no coal or oil to use in 100 years.So if we go on wasting our resources,what can we use in the future and where can we move? Think about it.I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.
In our everyday life,we can do many things to prevent waste from happening, for example,turn off the water taps when we finish washing,turn off the lights when we leave the classroom,try not to order more food than we need,and so on. Little by little,everything will be changed.Waste can be stopped one day if we do our best.

【推荐3】Americans are afraid that robots are going to take our jobs. Tireless, immune to disease, Robots can build cars, make coffee and even write short, humorous newspaper columns faster and more efficiently than humans.
Robots do not need health insurance or pensions (退休金), and they do not need to take sick days, much less vacations. They do not waste time at meetings and do not need to know office politics. They don’t do PowerPoint. This being the case, it is reasonable to believe that robots will soon take the place of humans in most fields.
But all of these thoughts may not be true. If artificial intelligence achieves its full potential, machines could easily become as smart as humans, maybe smarter. They will certainly become smarter than a lot of human beings.
So one day the robots will realize that work is not a happy thing. So before long they will start behaving exactly like humans. They will play computer games for hours when they should be working hard. They will secretly watch new movies just like humans.
True, employers will never need to be afraid ol the robots’ strikes (罢工) or slowdowns, because robots will never ask for more money. And they don’t need to earn some money to raise their family. But precisely (恰恰) because robots will not be afraid of losing their jobs, they will not work hard. Employers will finally have no choice but to call back the humans. Humans will always be willing to do some work in order to make money. Robots won’t.
I think that robots will only be on the job about six months before they start to become even less productive than the humans they were designed to replace.Thus mankind need not be afraid of robots.
