Your telephone is running low on power while you are waiting to fly out of an airport.
Then you discover a public USB charging area close by. 【小题1】 Then you take a deep breath and sit back, happy to get the power for free.
What could go wrong? Plenty.
In addition to providing an electrical current, phone charging cords can send and receive data. That free USB charging hub at an airport, hotel or any other public place may not only charge your phone. 【小题2】 The USB charging hub could be connecting to your phone and copying your contact list, email and text messages, voice mail, photographs and videos. It can also copy passwords, banking information and any other information stored on your phone.
If you want to charge your phone while traveling, you have other choices that do not increase your risks.
Connect your phone only to electrical outlets so data transfer is not possible. 【小题3】 It is better to use a distant wall outlet than a nearby USB charging hub.
Carry an extra, fully-charged battery. Having one means you can charge your phone without having to worry about carrying a special cord or finding a power outlet. 【小题4】
If you must use a public USB charging center, be sure to turn off your phone completely.
【小题5】 But it will reduce the chances of it happening, depending on what phone you have.
A. Remember to fully charge your phone before you leave home or work.
B It also could be transferring information to and from the device.
C. The public USB charging hub may even download programs to your phone.
D This may or may not prevent data transfer.
E. You can charge your phone with the extra battery wherever you are.
F. An available outlet may not be as near as a USB charging hub, but the few extra steps may keep you safe.
G. You quickly reach for a charge cord and connect your phone to the charging hub.

The Loss of Innocence
Innocence is such a precious gift. It’s explained as freedom from guilt or wrong doing. Just imagine never having to worry about anything and having a guilt free mind. Some people wish to save this kind of innocence from being lost from childhood to adulthood.
What would the world be like if innocence were never lost? One way it would benefit humanity is the lack of hatred （仇恨）among the world. During youth, there may be an occasional argument, even a little physical fight, but nothing like firing a handgun at a fellow human being. And children are blind towards the racial differences of others. A kid will hang out with any other kid. It is the lack of innocence and the ignorance we learn from adults that influence children otherwise. Another benefit is the constant desire for fun and adventure. With very little if any time at all for fun，the adventurous mind is lost in time with the responsibilities placed upon adults. If innocence were kept alive, these ambitions would never depart from our lives.
However, other people actually hate the idea of innocence lasting for ever. They feel that the lack of organization and mental power of those with innocence would cause extremely destructive consequences to society in general. A large number of individuals would never have the urge to learn, work, and act upon the necessary needs for humanity to survive. Without a proper education which is usually provided by those who no longer live in a world of innocence, people would not have the desire to succeed, get a good job in life, or provide income for their families, which would hurt the lives of children.
The lack of a good education and career would also harm the economy. As long as innocence is kept alive, no one would be terribly angered at the lack of effort people put out in the workplace, resulting in a strong decline in production and quality of needed goods.
Maybe it is wrong in wanting to save innocence. It sure is a nice thought, though. Perhaps innocence was meant to be lost. It was God’s will to make things the way they are, and there is a good purpose for everything. All that remains to be said about innocence is to enjoy it while it lasts.

Humans use electricity to light up the night sky. But did you know that nature itself can glow, too?
【小题1】. Some use their lights to communicate. Others shine to hunt, to mate or to protect themselves. The vampire squid, for example, gives out a cloud of light to scare enemies.
【小题2】.
In 2013, the US company Gleaux said it had created the world’s first light-producing plant, reported the Daily Mail.
【小题3】.
“People have dreamed about this stuff for many years,” said Alexander Krichevsky, the company’s founder.
He and other researchers are working toward a future in which glowing plants replace lamps and glowing trees line highways.【小题4】, making them glow to let farmers know when they need water or are ready to be picked.
While GleauX is working on glowing plants, the French company Glowee is trying to use glowing bacteria to light up shop windows and street signs. It is the same type of bacteria that causes certain sea animals to light up.
【小题5】.The company is now working on a light that shines brighter, lasts longer and comes in different colors.
“Our goal is to change the way we produce and use light,” said Glowee founder Sandra Rey. “We want to offer a global solution that will reduce the 19 percent of electricity consumption used to produce light.”

A．People are also creating glowing bacterial art that you can hang in your home

B．Scientists have found many glowing creatures, most of which live in the ocean

C．Krichevsky also hopes the technology could be used in crops

D．Researchers around the world are looking into nature’s lights for new ideas

E. It is a genetically-modified plant that glows like fireflies do
F. In 2016, Glowee created a bacteria-powered light that glows for three days

More than loo genes are related with increased risk of developing schizophrenia（精神分裂症）,bipolar disorder （躁郁症）and alcoholism（酗酒）,confirms a large study published in the recent issue of the British scientific journal Nature.
The world's largest study into the genetic basis of mental illnesses was led by researchers from British universities,including University College London (UCL),Cardiff University and King's College London (KCL).
Researchers believe that they are now much closer than before to understanding the complex biological causes, which make some people being at high risk of developing mental illnesses.They also believe that these findings could lead to new treatments.
The researchers analyzed the DNA of about 37,000 patients with schizophrenia,bipolar disorder or alcoholism, and compared the smallest genetic changes to those found in about 113,000 healthy people.They then identified about 128 independent genetic variants（变体）at 108 locations on the human chromosomes（染色体）that contribute significantly to developing schizophrenia—83 of these sites have never before been linked to the illness,according to scientists.
For example,people with the variant of the GRM3 gene,thought to be important in brain signaling,are around 2 to 3 times more likely to develop schizophrenia or alcohol dependence.The variant,which is found in approximately one in every 200 people,is also associated with a three times risk of developing bipolar disorder.
"We could be looking at the next big drug target for treating mental illness,"Professor David Curtis from UCL, co-author of the paper,said."The work opens up new ways to prevent and treat mental illnesses by revealing the mechanisms involved in their development."
【小题1】What can we learn from Paragraph 3?

A．Researchers are disappointed at curing biological causes.

B．Researchers are worried about the complex biological causes.

C．Researchers have found the method of curing biological causes.

D．Researchers are confident for figuring out the complex biological causes.

【小题2】According to Paragraph 4,the researchers found      .

A．there are 37,000 patients with mental illnesses in the world

B．most of the sites have never before been linked to mental illnesses

C．there is little difference between the patients and the healthy people

D．the cause of mental illnesses has nothing to do with the genetic changes

【小题3】We can learn from Paragraph 5      .

A．the variant of the GRM3 gene is important

B．the number of people with the variant of the GRM3 gene is large

C．the number of people with the variant of the GRM3 gene is small

D．people with the variant of the GRM3 gene aren't likely to suffer schizophrenia

【小题4】What's the main topic discussed in the text?

A．The importance of gene variants.
