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 |
Maggie was very glad that James was not a frequent visitor to the house. So far as the children were concerned, they had a mystery about him that stirred their imagination. He stirred Maggie’s anger, however, so that she often said to her husband, “It’s mercy that brother of yours doesn’t come oftener.”
In fact James came once a year, unexpectedly, around eight o’clock in the evening, and he stayed for six hours of close discussion with his brother. His arrival was a signal to the children that their bedtime would be delayed. Not that he ever spoke to them or played with them. He took no notice of them, as if he was unable to see children, at least until the time came for him to go. Instead, after his first greeting and a careless kiss, James took no notice of Maggie either, except to add, “You’ll be getting on with the supper, Maggie.” Such was his regard for her.
Maggie paid him back in her own way. She kept the children up, the four of them, to keep her company, she said, but of course they sang and made a noise and broke the endless sound of James’s voice. Very late, they dropped off to sleep in their chairs. Then, when James was about to go, Maggie woke them up and so more or less forced him to part with four shillings before he left. That gave her some satisfaction, for James, though rich, was mean. He always went home by the last train, just after two o’clock.
Maggie’s children secretly stared at their uncle. They could not forget that he had, in their mother’s words, “lost two wives and taken a third, ” They wondered about those two unfortunate lost ladies. They asked each other what their fate had been, and if neither could ever be found again. James never brought his third wife with him nor ever mentioned her. The children decided that he must be so frightened of losing her that he never allowed her outside the door. The underlined word “mercy” in the text most probably means _______.
| A．loss | B．wonder | C．lucky thing | D．terrible thing |

What do we know about James’ behavior?
| A．He was a kind man, with love for the family. |
| B．He was generous, especially towards his brother. |
| C．He was anxious to please the family, especially the kids. |
| D．He was rude to his sister-in-law. |

Spending as little as $5 a day on someone else could significantly boost happiness, the team at the University of British Columbia and Harvard Business School found on Thursday.
Their experiments on more than 630 Americans showed they were measurably happier when they spent money on others—even if they thought spending the money on themselves would make them happier.
“We wanted to test our theory that how people spend their money is at least as important as how much money they earn,” said Elizabeth Dunn, a psychologist at the University of British Columbia. They asked their 600 volunteers first to rate their general happiness, report their annual (yearly) income and detail their monthly spending including bills, gifts for themselves, girls for others and donations to charity.
“Regardless of how much income each person made, those who spent money on others reported greater happiness, while those who spent more on themselves did not,” Dunn said in a statement.
Dunn’s team also surveyed 16 employees at a company in Boston before and after they received an annual profit-sharing bonus of between $3,000 and $8,000. “Employees who devoted more of their bonus to pro-social spending experienced greater happiness after receiving the bonus and the manner in which they spent that bonus was a more important predictor of their happiness than the size of the bonus itself” they wrote in their report, published in the journal Science.
They gave their volunteers $5 or $20 and half got clear instructions on how to spend it. Those who spent the money on someone or something else reported feeling happier about it.
“These findings suggest that very minor alterations (changes) in spending allocations (shares)—as little as $5—may be enough to produce real gains in happiness on a given day，”Dunn said. What is the general idea of the passage?
| A．The more you earn, the greater happiness you will get. |
| B．Spending more money on yourself will make you happier. |
| C．Money can buy happiness, but only if you spend it on someone else. |
| D．You can spend only 5$ a day to get happiness. |
The underlined word “boost” in the first paragraph probably means_______.
| A．help to find | B．help to bring | C．help to increase | D．help to get |
Which of the following statements is NOT true according to the passage?
| A．Those who spend more money on others can get much more bonus. |
| B．People usually think spending money on themselves will make them happier. |
| C．Very small changes in spending your money may be enough to gain happiness. |
| D．Researchers think that how people spend their money is at least as important as how much money they earn. |
It can be inferred from the 6th paragraph that ______.
| A．the volunteers not given 5$ or 20$ spent their own money on themselves. |
| B．those who spent the money on someone or something else felt happier about it. |
| C．the volunteers were given 5$ or 20$ as a reward for the experiment. |
| D．half of the volunteers could spend the money as they liked. |

It may help you to know that there is no such thing as a perfect speech．At some point in every speech, every speaker says something that is not understood exactly as he has planned．Fortunately, the moments are usually not obvious to the listeners. Why ? Because the listeners do not know what the speaker plans to say. They hear only what the speaker does say. If you lose your place for a moment, wrongly change the order of a couple of sentences, or forget to pause at a certain point, no one will be any the wiser．When such moments occur, don’t worry about them. Just continue as if nothing happened．
Even if you do make an obvious mistake during a speech, that don’t really matter. If you have ever listened to Martin Luther King’s famous speech – “ I have a dream”, you may notice that he stumble（结巴）his words twice during the speech．Most likely, however, you don’t remember．Why? Because you were fixing your attention on its message rather than on his way of speech-making. People care a lot about making mistakes in a speech because they regard speech-making as a kind of performance rather than as an act of communication. They feel the listeners are like judges in an ice-skating competition．But, in fact, the listeners are not looking for a perfect performer. They are looking for a well-thought-out speech that expresses the speaker’s ideas clearly and directly．Sometimes a mistake or two can actually increase a speaker’s attractiveness by making him more human．
As you work on your speech, don’t worry about being imperfect．Once you free your mind of this, you will find it much easier to give your speech freely．The underlined part in the first paragraph means that no one will ___________．
| A．be smarter than you | B．notice your mistakes |
| C．do better than you | D．know what you are talking about |

| A．your attention is on the content |
| B．you don’t fully understand the speech |
| C．you don’t know what the speaker plans to say |

It can be inferred from the passage that ___________
| A．giving a speech is like giving a performance |
| B．one to two mistakes in a speech may not be bad |
| C．the listeners should pay more attention to how a speech is made |
| D．the more mistakes a speaker makes, the more attractive he will be |
What would be the best title of the passage?
| A．How to Be a Perfect Speaker |
| B．How to Make a Perfect Speech |
| C．Don’t Expect a Perfect Speech |
| D．Don’t Expect Mistakes in a Speech |
When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure—and so soon—that another ant is dead.
One scientist recently came up with a way to explain this ant behaviour. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.
But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.
To test his theory , Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical overrides the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.What is the function of the first paragraph?
