The bed should be reserved as a place for sleep, but people tend to read an iPad a lot in bed before they go to sleep.
Charles Czeisler, a professor at Harvard Medical School, and his colleagues got a small group of people for an experiment. For five days in a row, the people read either a paper book or an iPad for four hours before sleep. Their sleep patterns were monitored all night. Before and after each trial period, the people took hourly blood tests to paint a day-long picture of just how much melatonin (褪黑激素) was in their blood at any given time.
When subjects read on the iPad as compared to the paper books, they reported feeling less sleepy at night and less active the following morning. People also took longer to fall asleep on the iPad nights, and the blood tests showed that their melatonin secretion (分泌) was delayed by an hour and a half.
The researchers conclude in today's journal article that given the rise of e-readers and the increasingly widespread use of e-things among children and adolescents, more research into the long-term consequences of these devices on health and safety is urgently needed. Czeisler and colleagues go on, in the research paper, to note：“Reading an iPad in bed may increase cancer risk.”
However, software has been developed that can reduce some of the blue light from the screens of phones and computers according to time of day, and there are also glasses that are made to filter (过滤) short wavelengths. While they seem like a logical solution for the nighttime tech users, it needs more research.In Charles Czeislers experiment, all the subjects were asked to______.
| A．sit in a row and receive the strict tests |
| B．have their sleep patterns observed all night |
| C．read a paper book and an iPad at the same time |
| D．have their blood tested per hour during the trial |
The third paragraph tells us the iPad readers were likely to____________.
| A．feel less sleepy and tired in the day |
| B．fall asleep more easily after reading |
| C．become less energetic the next morning |
| D．have a lot more melatonin secretion |
The special software recently developed can______.
| A．remove the blue light from your devices completely |
| B．help prevent eyes being harmed by short wavelength |
| C．weaken the harm done by doing nighttime e-reading |
| D．be used in all the e-things widely and safely |
Which of the following can be the best title for the text?
| A．No e-reading in bed before sleep |
| B．New software for night e-readers |
| C．Wrong behaviors before bedtime |
| D．No games on iPad in bed |
A study has found, spending hours playing violent video games prevents teenagers from their moral growth. It is thought that regular touch to violence and lack of contact with the outside world makes it harder for them to tell right from wrong．They also struggle to trust other people，and see the world from their viewpoints．
Researchers from Brock University in Ontario found that those who spend more than three hours each day in front of the screen are particularly unlikely to have developed the ability to empathize(同情)．
The Canadian researchers surveyed 109 boys and girls，aged 13 and 14，about whether they played video games，which games they liked，and how long they spent playing them．Their findings found that 88 percent of teens said they played games，and more than half admitted to playing games every day．Violent games were among the most popular．
The teenagers also filled in a questionnaire designed to measure their moral development．For example，they were asked how important it is to save the life of a friend．
Previous studies have suggested that a person’s moral judgment goes through four phases as they grow from children and enter adulthood．By the age of 13 or 14，scientists claim young people should be entering the third stage，and be able to empathize with others and take their viewpoints into account．The research found that this stage appeared to be delayed in teenagers who regularly played violent video games．
It is also thought that teenagers who play games regularly did not spend enough time in the real world to learn to take others’ thoughts into consideration．Researcher Mirjana Bajovic said：“The present results indicate that some teenagers, who spent three or more hours a day playing violent video games，are deprived of such opportunities．” he added：“Touch to violence in video games may influence the development of moral reasoning because violence is not only presented as acceptable but is also justified and rewarded．”
They concluded that rather than trying to enforce an ‘unrealistic’ ban on the games，parents and teachers should encourage teenagers to do charity work and take up after-school activities．Why did the Canadian researchers carry out the studies?
| A．To develop teenagers’ ability to communicate. |
| B．To enrich teenagers’ awareness of social life． |
| C．To discuss how to save the life of a friend． |
| D．To measure teenagers’ moral development． |
What does Mirjana Bajovic want to tell us according to his words?
| A．Playing games regularly will improve teens’ intelligence. |
| B．Vio1ent games cost teens social experiences in real life． |
| C．Playing games makes teens help others. |
| D．Playing games inspires teens to develop fast. |
What would be the result of playing violent video games?
| A．Getting teens hard to take others into consideration. |
| B．Causing teens easier to tell right from wrong． |
| C．Helping teens make more good friends． |
| D．Making teens easy to get along with． |
What can be inferred from the text?
| A．Playing video games should be forbidden among teens. |
| B．Parents and teachers should let teens go online． |
| C．Teens should be encouraged to do more meaningful things. |
| D．Game designers should be kindly treated and rewarded. |
As the saying goes, man struggles upwards; water flows downwards. Water runs downhill from mountaintops to streams to rivers to oceans. But downhill isn’t the only way that water moves .A new study measures how water travels from country to country for human consumption. This flow isn’t the type we usually think about .These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports. They call this a flow of “virtual water（虚拟水）”.
We typically think about water as the liquid that flows from a tap. However,92％of the water used by people goes into growing crops，according to water researcher Arjen Hoekstra. He recently studied the hidden travels of virtual water used in products made from things like crops and meats .These products are shipped around the world.
For example, consider a sugary soft drink. Hoekstra estimated that to produce one half-liter of the drink requires between 170 and 310liters of the water—about 95％—is used to grow and process the ingredients(原料).Another 4％goes into the packaging and labeling. In Hoekstra’s calculation, when one country produces a half-liter of soda and sells it abroad，it exports as much virtual water as would fill a large refrigerator．
According to Hoekstra’s new report，dry countries like Israel and Kuwait，both in the Middle East,get the majority of their virtual water from other countries，through imported products. More surprisingly, some wetter countries，like the Netherlands and the United Kingdom, also get the majority of their virtual water from other places. That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries.
In the United States most of the virtual water used comes from American sources .In China even less of the water associated with its products.The example of a sugary soft drink in Paragraph 3 is given to show_________.
| A．how drinks are shipped |
| B．how virtual water is exported |
| C．how virtual water is used |
| D．how drinks are made |
In which countries does most part of virtual water come from outside?________
| A．Kuwait and the Netherlands |
| B．China and the United Kingdom |
| C．America and the Netherlands |
| D．Israel and America |
What is the best title for the passage?
| A．Crops and Virtual Water |
| B．Water’s worldwide travels |
| C．Benefits of Virtual Water |
| D．Import and Export of Water |
The passage is most probably a________.
| A．science news report | B．science fiction story |
| C．newspaper advertisement | D．book review |

You may never think a documentary film could have aroused so much public enthusiasm in Chinese history. Nowadays everybody is talking about a new 7-part documentary called A Bite of China which was recently broadcast late at night on CCTV I. The documentary describes various gourmet items across the vast Chinese culinary (烹饪) landscape.
According to Taobao, China’s biggest online retail website, just five days after the series began to air, nearly 6 million people went to the site in search of various local specialties, particularly those mentioned in the documentary. More than 7.2 million deals were concluded. A ham producer from Yunnan Province saw his sales grow 17-fold in five days.
However, one can’t help but believe that the documentary’s popularity is probably linked to the endless stream of terrible food security issues that have emerged in recent years. In one well-received article, a netizen wrote, “I wonder how many felt so empty-hearted and sighed after watching the film. Blue-vitriol watered chive, formaldehyde(甲醛) sprayed cabbage, Sudan Red colored salty eggs, restaurants using gutter oil. The list is long…”
A varied and ancient food culture that is famous world-wide and which should have made the Chinese proud ends like this: one can only sigh. Food is the most vital thing in people’s lives. Yet China’s food industry is a typical description of “bad money driving out the good”.The market is huge while the cost of faking and cheating is so low for immoral businessmen; and the punishment is too light. Take the milk industry as an example. Although Sanlu, the company that sold the melamine-adulterated milk powder, was punished, thousands of other dairies didn’t work hard to improve the quality. In order to allow national brands to survive, Chinese authorities are happy to loosen their regulations.
As the documentary shows, people are attracted not to gourmet items like matsutake, a species of rare mushroom grown naturally in remote forests, but to common Chinese dishes like barley, lotus root or tofu. They are what meet our basic needs. This explains why people are so excited about A Bite of China---it is a reminder that there is still a world out there where food is excellent and people have dignity.The underlined word “gourmet items” probably means_______.
| A． delicious food | B．latest technology |
| C． beautiful clothes | D．great inventions |
The second paragraph mainly talks about______.
| A．the content of the documentary |
| B．the producer of the documentary |
| C．The popularity of the documentary |
| D．the history of Chinese gourmet |
We can infer from what a netizen wrote in one well –received article that _____.
| A．the price of food is too high for many common people |
| B．the documentary was made by a world-famous Chinese director |
| C．there is a huge contrast between the ancient food culture and the reality |
| D．none of the television viewers have a knowledge of the Chinese food culture |
According to the passage, China’s food industry is full of faking and cheating because_____.
| A．there are still so many poor people at the present time |
| B．the punishment for unscrupulous businessmen isn’t serious enough |
| C．the Chinese government encourages it to do so |
| D．the food technology is not so advanced as in developed countries |
On Sept 18, they arrived before polling stations even opened, dressed in school uniforms, with book bags over their shoulders—and, for the first time in British history, ballot (选票) cards in hands.
More than 109,000 Scottish teenagers aged 16 to 17 took part in the Scottish independence referendum (公民投票), in which Scotland eventually decided not to become independent.
The age group only made up a small part of the 4.29 million total voters, but they have “demonstrated how the youngest voters can be some of the most enthusiastic in a mature democracy”, commented The Associated Press. Casting their ballots, they were “proud and passionate” to help their nation decide whether to break away from the UK after 307 years in union.
“You feel like you’ve got a say, because it is going to be you. You are going to decide what it is like when you’re older,” 16-year-old Erin Cheshire in Glasgow, who voted “yes”, told The Wall Street Journal.
At age 16, Scottish residents are allowed to join the military, get married, and work. Eighteen is the legal drinking age, as well as the UK’s voting age. But in 2013, Scottish law was changed to allow 16- and 17-year-olds in Scotland to vote in the referendum. The government pushed for the change because “younger voters are more likely to vote with their hearts, not their heads—and embrace fundamental change by voting for the pro-independence Yes Scotland campaign”, NBC News said.
But when the decision was handed down, some worried that high school students might not be as informed as adult voters. However, many experts said that assumption was wrong.
Professor Jan Eichhorn of the University of Edinburgh insisted that Scottish teenagers were as likely to read newspaper articles and campaign materials as their parents. They would simply get these resources through social media.
“There’s no evidence to suggest that they’re less capable than adults of voting, from a research point of view,” Eichhorn told NPR.
Scotland’s move to let younger teenagers vote in the referendum has led to a discussion about whether the voting age ought to be lowered to 16, both in the UK and the US.
“By 16, most people have about as stable an ideology (思想意识) as they are going to get,” Professor Jason Brennan of Georgetown University wrote for CNN, arguing that the US should also think about allowing younger US citizens to vote. The Scottish independence referendum was held on Sept. 18 ______.
| A．to encourage youngsters to be concerned with politics |
| B．to lower the minimum voting age to 16 for the referendum |
| C．to elect who would be the new leader of Scotland |
| D．to decide whether Scotland would become independent from the UK |
According to the passage, we can learn ______.
| A．It is possible for the USA to lower the voting age to 16 in the future. |
| B．Scotland gained its independence from the UK eventually. |
| C．All the people in Scotland thought highly of the government’s decision to lower the voting age to 16. |
| D．Scottish teenagers aged 16 are allowed to join the military, get married, work and drink alcohol now. |
What doe the underlined word “embrace” (in para.5) probably mean?
| A．Approve of | B．Object to |
| C．Know about | D．Admit to |
What is Jan Eichhorn’s opinion of the Scottish teenagers aged 16 to 17?
| A．They are too enthusiastic to make informed decisions. |
| B．They make no difference to the voting result. |
| C．They are as informed and capable as adults of voting. |
| D．They are unwilling to be involved in the decision of the country’s future. |
