Popular part-time jobs for teens include babysitting, delivering (递送) newspapers, restaurant work and shop work. Children in Britain can work two hours a day at the most on a school day but not during school hours. During weekends and school holidays, they can work longer hours.

    Bank accounts (账户)

    Some children and teenagers have a bank account. There is no age limit at which you can open a bank account, but a bank manager can decide whether to open an account for a child or a young person. Parents can put pocket money directly into their child's bank account. Most banks have a prepaid bank card designed for young people.

    Mobile apps

    Many companies have made mobile apps for children, including GoHenry, Osper and Gimi. Parents can add money to their children's accounts and check to see how the money is spent. Children can choose to save their money or spend it using a card. The apps suggest that kids from 8 to 13 can use the cards.

Have you ever had lucid (清醒的) dreams? Recent studies suggest that the number of people having them is on the rise. Someone having a lucid dream realizes they are dreaming and may from then on" direct" the action, or they may simply " watch" the dream unfold. The sense of awareness (知道) makes it different from a dream that is simply very lively and true to life. And although the description may seem strange, the process is far from alien to many of us.

Studies suggest that the number of people in the Western world experiencing lucid dreams, which happen once in a while, has risen by between 10 and 40 per cent since the 1980s. Today, they are so common that about one in eight of us will have one in our lives. But still, little is known about what causes them or what is behind the rise.

Research carried out at the respected Harvard University in the US shows that the brain is working hard during lucid dreams. In fact, the level of the mental (精神

的) activity in some parts of the brain is similar to that of a person who is awake. Lucid dreamers seem to share certain personal characters. For example, in general they are quite creative. They are also good at digging deep into problems and going out of their way to solve them. Furthermore, they always believe in personal responsibility rather than letting society carry the can.

Our nightmares (噩梦) may show our waking worries, with the five most common ones-- falling, being run after, feeling disabled, being late and the death of a loved one. Men are more likely to have nightmares about fights or being fired while hair and tooth loss appear more in women's nightmares-perhaps showing worries about losing their looks. Research has also found that women have more nightmares than men. Their dreams are also scarier and more unforgettable.

Imagine （想象） walking into a movie theater without being greeted by the smell of popcorn. It's hard to believe, isn't it? For many people, popcorn goes hand in hand with movies. They can't have one without the other. But 1  did this happen?

The 2  between the two is younger than you may think. In the mid-1800s, popcorn was already a popular snack in America. Vendors sold it on the 3  . People, especially kids, loved this street food. In the early 1900s, vendors started to sell popcorn 4  movie theaters.

However, theater owners didn't like popcorn. They believed it would make the experience of watching a movie 5  enjoyable. Eating it would make too much noise during the silent movies.

Later, when movies added sound, the 6  noise problem went away. More and more people went to the movies. Some of them even secretly（秘密地） took popcorn into the theaters. Later, more movie theaters 7  . Some of them agreed people to eat popcorn while they were watching movies.

In the 1930s, the theater owners found that people didn't need to buy popcorn from street vendors. Because popcorn was 8  to make, they could make and sell it themselves. They did that and the smell of popcorn drew more people to their theaters. The 9  made a lot of money, and people enjoyed themselves at the movies.

Today, popcorn is still an important part of the movie-going experience. Roles, a man who once ate three bags of popcorn, said, "People come to theaters sometimes just for the 10 . They don't even care what is playing!"
