I 次の英単語で最も強く発音する部分(第一アクセント) を、 それぞれ記号で答えなさい。 1. del-i-cate アイウ 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. 2. a-bil-i-ty 3. access 4. va-ri-e-ty 5. in-tro-duce アイウエ アイ アイウエ アイウ () cell phone: ## 1.

10 15 3 experimenting with music. Scientists in an English university are They want to know what music makes customers spend money. What they did was to play different kinds of background music in a restaurant. They watched carefully and recorded what happened. They found that customers spent 22 pounds on average when However, if they played soft, classical music, customers spent over 24 pounds. That's 10 percent more! they played pop music. "According to our research, music does affect people's moods. Classical music makes customers feel rich and sophisticated," says 10 Dr. Adrian North from the University of Leicester. "They then buy luxury items, such as appetizers, desserts and coffee." Interestingly, if there was no background music, the customers spent only 21 pounds on average. They spent less because they skipped some of the luxury items. 5 レストランや喫茶店では音楽を流していますね。 あの音楽によって売上に変化はあるのでしょうか。 の科学者が実験を行いました。 その結果は...
