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.

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism (新陈代谢) becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious circle in its tracks, people need to consume food and supplements that will neutralize the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.
1.It can be inferred from Para. 2 that __________.
A． foods with natural enzymes help people keep fit
B． we’d better be cautious about raw and whole foods
C． it is essential for people to protect their vital organs
D． giving up cooked and refined foods is a new lifestyle
2.Processed foods are unhealthy because they __________.
A． destroy body’s cells
B． stop body’s metabolism
C． may lead to obesity
D． are difficult to digest
3.What is the main purpose of this passage?
A． To warn people of the problem of obesity
B． To advocate eating more raw and whole foods.
C． To inform people of the harm of processed foods.
D． To tell the differences between raw and processed foods.
4.The underline word “vicious” in the last paragraph probably means ____________.
A． violent
B． progressive
C． positive
D． harmful

Dolphins(海豚) live in a dark underwater world. It’s often impossible to see each other or anything else around them, so sound plays an important role in their survival. To communicate with each other, dolphins produce all kinds of sounds.
Only other dolphins understand what the sounds mean. Scientists haven’t uncovered their secret communication, except for one kind of whistle. It might last less than a second, but this whistle is a big deal. Why? Because these whistles are actually names of dolphins - and every dolphin has one. Scientists call these sounds a “signature whistle.” When other dolphins hear the whistle, they know which dolphin is calling.
Dolphins often hunt by themselves but still need to stay connected to the group. Since they can’t always see each other, dolphins use their signature whistles to check in with other dolphins hundreds of yards away. “In coastal areas, dolphins exchange whistles even when they’re a third of a mile apart,” says Greg Campbell, who studies animals. That means dolphins shout out to group members that might be nearly five football fields away.
What’s amazing is who names the baby dolphin. Not the mother. Not an auntie dolphin or another group member. Scientists believe the baby dolphin itself comes up with the signature whistle. Like human babies, a baby dolphin plays with sounds throughout its first year. While testing its sound skills, a baby dolphin is doing something amazing. It’s creating or figuring out its signature whistle. How or why it chooses its signature whistle is not clear. Studies show that most of the time the signature whistle is nothing like its mother’s or group members’ whistles.
When the baby dolphin is about a year old, its signature whistle is set. It repeats it often so the other dolphins learn to recognize it.
Deciphering(破译) dolphin names is just the beginning of figuring out what dolphins communicate about. Do they chat about sharks? Discuss the tides? Maybe they even have a name for people. Someday scientists are to decipher the rest of dolphins’ communication.
1.Sound is important for dolphins because of ______.
A．their poor sense of direction
B．their living environment
C．their strong enemies
D．their big groups
2.The dolphin’s signature whistle ______.
A．lasts along time
B．can travel long distances
C．is especially helpful in hunting
D．can be recognized by other animals
3.The author writes the text mainly to _____.
A．encourage readers to study dolphins
B．tell readers how dolphins communicate
C．show how lovely and clever dolphins are
D．introduce a special sound made by dolphins
4.A baby dolphin gets its name ______.
A．soon after it was born B．according to its size
C．all by itself D．with the help of its group

Three Critical Truths We Forget All Too Soon
So much happens in our lives every day that we often forget what we have learned. In effect, the only thing faster than the speed of our thoughts is the speed of our forgetfulness. 1.
●Small steps get you to big places.
The greatest of all mistakes is to do nothing simply because you can only do a little. In fact, it is far more productive to take many small steps in the right direction than to make a giant leap. 2.Figure out where you want to go, take a step, and keep on stepping. Diligence and persistence will get you there.
● 3.
Two people can be affected by the same circumstance but respond in completely different ways. The reason is that it just depends on their attitudes. When you expect life to be unkind, it will always live up to your expectations. On the other hand, when you consider yourself to be in a fortunate situation, you will find yourself in many more. 4.
●You can only change yourself.
Don't wait for someone who hurt you to make it up to you; this kind of thinking only keeps your old wounds from healing. 5. You have no control over them, and they may never change. Inner peace is found by changing your thinking, not the people who hurt you. So forgive those who have hurt you in the past, and even more importantly, forgive yourself for allowing them to hurt you. Then smile like you've never cried re-open your heart and mind like you've never been hurt, and live the rest of your life like you're running out of time.
A. Fear always exists.
B. Attitude makes all the difference.
C. The path to every goal requires a hundred small steps--one after the other.
D. Here are some important reminders to jog your memory.(唤起记忆)
E. Waiting for them to change is not the answer.
F. In the end, we learn even more from our failures than we do from our successes.
G. It’s important to remember that there is value in every situation and circumstance.

The Washington post – NASA’s newest space habitat looks sort of like a kids’ moon bonce, a big, bright, inflatable globe that could be lots of fun to play in. Soon astronauts on the International Space Station could get the chance to try . The expandable habitat made by Bigelow Aerospace recently passed NASA’s strict certification requirements and is scheduled to be flown to the station in September.
Called the BEAM ( Bigelow Expandable Activity Module), the habitat would be attached to the space station, where it would stay for two years. While there, it would be tested to see how it handles the rigors of space – the radiation, the station’s movement and even how it stands up to the debris (碎片) flying around in orbit.
The private Las Vegas company, founded by millionaire real estate mogul(地产大亨) Robert Bigelow, won a $17.8 million contract from NASA to provide the module to the space station.
“Today is the first step, but it’s a big step,” said Bigelow’s George Zamka. Replace the space station or make it larger. It also hopes to build the habitats on the moon. Its B330 module would be even bigger, with 330 cubic meters of internal (内部的 ) space. The modules could be connected. Creating research facilities, the company says, or even space hotels.
In an interview ,NASA’s William Gerstenmaier, said he was eager to see how the module performs , and said he was especially pleased “ to see how the private sector can step up and help us meet our requirements.” The module will be flown to the space station by SpaceX, the first commercial company to res
upply the space station.
1.What would be the best title for this passage?
A. NASA’s space habitats flown to the station.
B. NASA’s space habitat it the station.
C. NASA’s new expandable space habitat.
D. NASA’s newest inflatable globe.
2.Which of the following is TRUE according to the passage?
A. NASA’s newest space habitat is a kids’ moon bounce.
B. Astronauts of Bigelow Aerospace could get the chance to try the space habitat.
C. NASA was founded by Robert Bigelow.
D. The B330 module to be built on the moon would be with an inside space of 330 cubic meters.
3.The underlined word “rigors” in Paragraph 2 refers to “_________”.
A. difficulties B. environments
C. movements D. changes
4.The passage is most probably taken from ________.
A. a newspaper B. a booklet
C. a magazine D. a science fiction
