Wang Mengshu, an expert at the Chinese Academy of Engineering, said at a group discussion on the sidelines of the annual session of the National People's Congress that Wi-Fi should not be provided on high-speed trains, as it might disturb communication signals 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 tiny screens of smart phones and laptops. However, on last Tuesday Beijing Youth Daily said it should be market demand that decides whether the Wi-Fi is offered on the trains or not.
An increasing number of residents, especially young white-collar workers, are addicted to their smart phones rather than face-to-face interactions, thanks to the extensive Wi-Fi coverage across the country. That partly justifies Wang's opposition to the offering of Wi-Fi on high-speed trains, because they are not supposed to be dependent on high-tech devices. It is also evident that passengers on trains without free Wi-Fi will use their smart phones and other mobile devices less. However, whether the trains should provide a free Wi-Fi service fundamentally depends on customer demand.
In other words, state-owned as it is, the China Railway Crop still 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 "for the sake of their well-being".
Free Wi-Fi, in fact, is already available 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. It requires proper guidance, not a total ban on the bus, to make up for the negative effects of high-end technologies, such as people's increasing addiction to smart phones.
1.Which is one of the reasons for Wang Mengshu saying no to free Wi-Fi on the train?
A. Making communication signals of trains stable.
B. Not focusing on the screens of phones and laptops.
C. A high cost of keeping trains in good condition.
D. Missing the beautiful views throughout a journey.
2.Which of the following best explains the underlined part in the second paragraph?
A. Some people go against Wang's proposal.
B. Wang's opposition proves reasonable in part.
C. Most people think Wang's suggestion hard to carry out.
D. Young white-collar workers consider Wang's advice right.
3.What does "market rules" in the 3rd paragraph refer to?
A. Demand depends on supply.
B. The market decides purchasing power.
C. Everything depends on money.
D. The market is in the control of customers.
4.According to the last paragraph, the author agree _______.
A. People should drop smart phones.
B. Every coin has two sides.
C. High-end technologies cause more side effects.
D. A total ban on free Wi-Fi is reasonable.

Although one might not think so as a result of the disadvantages, thousands and thousands of ads have shown advertising is of great importance to the society in which people live, either in the United Kingdom, or in many other parts of the world .Advertising is necessary as a means of communicating with others, of telling them about the goods and services that are offered, and of which most of them would never get to hear at all if it were not for advertising. And advertising does a great deal to a rising standard of living conditions.
In talking about advertisement, one should not think only a commercial on television, or an advertisement in the newspaper or magazines and—in the sense of communication—even the spoken or written words of salesmen. After all, the roots of advertising are to be found in the market place in the ancient times.
For many years it was thought that it was not enough to just produce goods and supply services. It is only more recently that people came to understand the production of goods would be a waste of resources unless those goods can be sold at fair price within a reasonable time period. In the competitive society in which we live, it is very important that we go out and sell what we have to offer, and advertising plays an important part, whether selling at home or in export market. Around 2 percent of the UK national product is spent on advertising. But it must be thought that this advertising tries to sell goods to customers who do not buy them. Of course, advertising does try to catch the eyes of the buyer, but if the product one has bought does not match what the advertisement had described, it is extremely unlikely that the goods will sell well.
1.According to the text, advertising is important to____.
A. every person in the world B. people with a high standard of living
C. some famous companies D. a large number of people in the world
2.What is the earliest advertisement in history?
A. Shop window show and wrapping of the goods.
B. Advertisements on TV
C. face-to-face talks between sellers and buyers
D. Products in many newspapers and magazines
3.The writer tries to tell us that goods will sell well if ____.
A. advertisements are well designed
B. enough money is spent on advertising
C. they are of high quality and well wrapped
D. advertisements mirror the true value

Instead of a normal court hearing, the trial on Wednesday appeared more like a prepared drama. Hundreds of reporters waited outside the court, in the hope of learning “shocking” information about the case, which includes well-known military singer Li Shuangjiang’s son, who gang-raped a woman with another four men on February.
The case was not a public hearing because it includes teenagers, whose privacy must be protected under law, but many details had been exposed by the lawyers before the trial.
Lawyers of all five suspects and the woman’s lawyer made a lot of debate on the Internet before the trial, making the case more confused.
Wu Ming’an, a law professor from the China University of Political Science and Law, said it was a pity to see such a “performance” by the lawyers.
“It can be understood that the two parties freely spoke their opinions, but it’s not professional or wise to see lawyers do the same,” Wu said. “Instead, the lawyers should guide and persuade their clients(当事人) to calm down, especially for such a non-public and sensitive case.”
China has no clear rule to manage lawyers’ behavior before trials, “but it should be general knowledge that the lawyers of the two sides cannot leak too many details, particularly in a case that includes teenagers”, Wu added.
Yi Shenghua, a lawyer who has been following the case, said it does more harm than good to both parties for such detailed information to be exposed before the trial.
“It’s OK for lawyers to speak, but what is said must be reasonable and legal. Although judgments should not be affected by public opinion, it’s hard for them not to be,” he said, suggesting judicial authorities should speak out if the case goes wrongly.
Trials must be conducted based on evidence, while lawyers should protect their clients’ rights instead of adding fuel to the flames, Yi said.
In my eyes, the most important aspect of the case, lies in how to make lawyers do their work more professionally and reasonably.
1.Why was the case not a public hearing?
A. Because it included the well-known military singer Li Shuangjiang’s son.
B. Because the victim was a woman.
C. Because teenagers’ privacy must be protected under law.
D. Because many details had already been exposed before the trial.
2.What is Wu ming’an’s attitude towards the lawyers’ behavior of making a lot of debate on the internet before the trial?
A. approval B. critical C. neutral D. indifferent
3.The underlined part “leak” in para. 6 refers to_________.
A. give away B. squeeze out C. break down D. sweep up
4.From Yi Shenghua, we know that _______________.
A. The lawyers’ behavior before trials hasn’t been ruled.
B. It doesn’t matter whether the detailed information is exposed before the trial.
C. What lawyers say must be reasonable and legal.
D. It is hard for judgments to be affected by public opinion.
