Ⅱ 次の英文を読み、 設問に答えなさい。
How many hours a day do you spend on your *cell phone?
Today, more and more young people are spending more and more time on smartphones and
computers. According (D) a 2013 *survey carried out by the *Japanese Cabinet Office, 97.2% of
high school students owned a cell phone; of these, 82.8% had a smartphone. This is a *drastic increase
from 2010, when only 3.9% of those with cell phones had smartphones. The survey also shows that the
spread of smartphones has led to increased access to the Internet among children, whose average
access time on a weekday is 107 minutes. The Cabinet Office also found that 40% of Japanese children
*log on to the Internet more than two hours a day, and that 8% spend more than five hours a day online.
This has led to some serious social and *psychological problems. Heavy Internet users become
*obsessed with staying online and @develop an *addiction to games, social media sites, and free
communication systems such as LINE.
The various *adverse effects of such addictions have been reported in most developed countries.
Many young addicts suffer (2) headaches and sleep disturbances such as *insomnia. They fail to
maintain normal weight *due to eating irregularities. And many are more likely to experience
emotional distress, isolation, anxiety, and depression. A British study suggests a clear link
between excessive Internet use (3) lower self-esteem. Those young people who spend more than
four hours a day looking at a screen are particularly *vulnerable to mental *disorders.
Several related studies conducted in China make clear the effects of Internet use on brain structure.
One study has shown that *volume @losses were seen in the *gray matter areas of Internet addicts'
brains. These areas are involved in people's ability to develop *empathy and compassion for others.
Another Chinese study used MRI scans to look at the brains of Internet-addicted teenagers and found
significant damage in the *white-matter nerve fibers connecting the brain areas governing emotions,
decision-making, and self-control. Similar (4) can be seen in the brains of heavy alcohol and drug
users.
