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.

Harbin is known as "the City of Ice". Usually, it has heavy snow from the early November. It's time for Harbin to come to life and attract visitors all over the world. 

Harbin Ice and Snow World has been a business card since 1999. This 816,682-square-meter park is the largest ice and snow theme park in the world. Visitors can enjoy more than 1,000 artworks made of ice and snow. And also, they can try the super ice slide (滑梯). The number of the ice slides this year is increased from 8 to 14 and the longest one is 512 meters. 

Visitors from the south of China is a large part of the tourism crowd. Chen Ling, a visitor, said, "I'm from Guangzhou. I come here to enjoy the hot winter. My trip will last about a week. I hope I will have a great time!" However, the southern visitors may be less prepared for the cold. So the local government gives the most important suggestion: Pack enough warm clothes. The more, the better. A Harbin taxi driver said, "My wife works in a hotel. These days we're busy but we both feel very excited. Ice and snow are important parts of our city. All the visitors are sure to feel the enthusiasm (热情) of us. Welcome to my hometown!"

You may feel bored in winter sometimes. But Harbin Ice and Snow World can make the long, cold months beautiful and creative.

Mother's Day first began in America. A mother was very kind. After she died, her daughter wanted to remember her so she wanted to make a day for all the mothers. In 1913, America decided to make the second Sunday of May to be Mother's Day and every family had to put up a national flag to show their love to mothers. Later, it became an important festival to remember and praise(赞扬) all the mothers in the world.

In China, some people want to make our own Mother's Day. There is a famous story about Mother Meng. She loved her son very much and did a lot for her son. Chinese people think she was a great mother, so people want to make lunar(阴历的) April 2nd to be the day. Because Mother Meng's son——Mengzi was born on that day.

On Mother's Day, children often help their mothers do some cleaning and they also buy gifts for their mothers. Some mothers even go for a trip and have some other activities to celebrate this day.
