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 |

About 1966 or so, a NASA(美国航空航天局) team doing work for the Apollo moon mission took the astronauts near Tuba City. There the landscape of the Navajo Reservation looks very much like the lunar surface. Among all the trucks and large vehicles were two large figures that were dressed in full lunar space suits.
Nearby a Navajo shepherd (牧羊人) and his son were watching the strange creatures walk about, occasionally being watched over by other NASA workers. The two Navajo people were noticed and approached by the NASA people. Since the shepherd and his son did not know English, they asked the NASA people who the strange creatures were. The NASA people told them that they were just men that were getting ready to go to the moon. The shepherd became very excited and asked if he could send a message to the moon with the astronauts.
The NASA officials thought this was a great idea so they provided a tape recorder. After the man gave them his message, they asked his son to translate. His son would not.

About ten years ago, a young and very successful businessman named Josh was traveling down a Chicago neighborhood street. He was going a bit too fast in his shiny, black, 12 cylinder Jaguar XKE, which was only two months old.
He was watching for kids rushing out from between parked cars and slowed down when he thought he saw something. As his car passed, no child came out, but a brick sailed out and — WHUMP! — it hit the Jag’s shiny black side door! SCREECH...!!!! Immediately Josh stopped the car, jumped out, seized the kid and pushed him up against a parked car. He shouted at the kid, "What was that all about and who are you? Just what the heck are you doing?!" Building up a head of steam, he went on. " That’s my new Jag, that brick you threw is gonna cost you a lot of money. Why did you throw it?" "Please, mister, please....I’m sorry! I didn’t know what else to do!" begged the youngster. "I threw the brick because no one else would stop!" tears were streaming down the boy’s face as he pointed around the parked car. "It’s my brother, mister," he said. "He rolled of the curb (路沿) and fell out of his wheelchair and I can’t lift him up. "Sobbing, the boy asked the businessman," Would you please help me get him back into his wheelchair? He’s hurt and he’s too heavy for me.
Moved beyond words, the young businessman tried hard to swallow the rapidly swelling lump in his throat. Straining, he lifted the young man back into the wheelchair and took out his handkerchief and wiped the scrapers and cuts, checking to see that everything was going to be OK. He then watched the younger brother push him down the sidewalk toward their home.
It was a long walk back to the black, shining 12 cylinder Jaguar XKE — a long and slow walk. Josh never did fix the side door of his Jaguar. He kept the dent (凹痕) to remind him not to go through life so fast that someone has to throw a brick at him to get his attention. Feel for the bricks of life coming at you.
