More and more people read an iPad in bed, reserved as a place for sleep, before they go to sleep.
Charles, a professor from Harvard Medical School% and hi& 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 f6r four hours before sleeps 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 the people 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 today5s journal article that because of the rise of e-readers and the increasingly widespread use of e-things among children and teenagers, more research into the long-term consequences of these devices on health and safety is urgently needed. Charles 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.

You can’t always predict a heavy rain or remember your umbrella. But designer Mikhail Belyaev doesn’t think that forgetting to check the weather forecast before heading out should result in you getting wet. That’s why he created lampbrella, a lamp post with its own rain sensing umbrella.
The designer says he came up with the idea after watching people get wet on streets in Russia. “Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy(伞蓬)built into a street lamp.” he said.
The lampbrella is a standard-looking street lamp fitted with an umbrella canopy with a built-in electric motor which can open or close the umbrella on demand. Sensors(传感器)first ensure that it starts raining and the motors open up in response to their sensors and then people can protect themselves from the rain under the canopies.
In addition to the rain sensor, there’s also a 360° motion sensor on the fiberglass street lamp which detects whether anyone’s using the lampbrella. After three minutes of not being used, the canopy is closed.
According to the designer, the lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lightning strike. Each lampbrella would offer enough shelter for several people. Being installed(安装)at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.
While there are no plans to take lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department, and insists his creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.
【小题1】What do we know from Belyaev’s words in Paragraph2?
A.His creation was inspired by an experience.
B.It rains a lot in the city of Saint Petersburg.
C.Street lamps are protected by canopies.
D.He enjoyed taking walks in the rain.
【小题2】Which of the following shows how the lampbrella works?
A.Motor→Canopy→Sensors.B.Sensors→Motor-Canopy.
C.Motor→Sensors→Canopy.D.Canopy→Motor→Sensors.
【小题3】What does paragraph 5 mainly tell us about the lampbrella?
A.Its moving speed.B.Its appearance.
C.Its disadvantages.D.Its safety.
【小题4】What can be inferred from the last paragraph?
A.The designer will open a company to promote his product.
B.The lampbrella could be put into immediate production.
C.The designer is confident that his creation is practical.
D.The lampbrella would be put on show in Moscow.

How old is “old”? 【小题1】 Two hundred years ago, you were old at 35. That was the average life then. At the turn of this century, as medical knowledge advanced, the average life span(长度) increased to 45. In 1950, 70-year-olds were really old. Today, a healthy 70-year-old is looking forward to many more active years.
So, how old is old? The answer is one you’ve heard many times, from all sorts of people. “You are as old (or young) as you feel!” The calendar(日历) simply tells you how many years you have lived.   【小题2】
Once an unknown author wrote,“  【小题3】. Nobody grows old by living a number of years; people grow old by giving up their goals.”
【小题4】. Alice Brophy, when she was with the New York City commission for the Aging, said, “It upsets me when people say, ‘Gee, you look young for your age!’ What does that mean? Is there some model that you’re supposed to look a certain way at 65 and 75 and 85? You know you can die old at 30 and live young at 80”
There are many wrong ideas about aging.  【小题5】. Here are some of the more common ones. For example, most older people are in poor health, or older people are unable to change.
A.It’s extremely terrible to be grown old.
B.Youth is not a time of life but it is a state of mind.
C.These ideas stereotype(固化) people on the basis of age.
D.Old is a point of view.
E. Older people are stubborn, unable to change.
F. The answer has changed over the years.
G. Your body tells you how well you’ve lived.
