New sea bridge opens in China

A new bridge just opened on October24.The long bridge links(连接)three cities. It is the HongKong-Zhuhai-Macao Bridge(HZMB).The bridge looks like the letter "Y ".It is 55 kilometers long. It is the world's longest sea bridge. China spent nine years building this bridge. The HZMB is not just a bridge, but also part tunnel(登道）and part island .In one part, the bridge turns into an undersea tunnel. The tunnel passes through two man-made islands. Large ships can pass by above the tunnel. The HZMB makes it much faster to travel between the three cities. It takes 45 minutes to go from Hong Kong to Zhuhai. In the past, it took four hours.

Chinese scientists made headlines last year by cloning（克隆）a pair of monkeys-Zhong Zhong and Hua Hua. Their names come from the Chinese words zhonghua, or "Chinese nation ". The monkeys were cloned using the same techniques(技术）that were used to produce Dolly, the world's first cloned animal, about 20 years ago. The monkeys could be used as a model to study genetic(遗传的）diseases, including some cancers(癌症）.

As one saying goes, where there are Chinese people, there are kungfu legends. Jin Yong was regarded as one of the greatest kung fu fiction writers in China. And for many people, he built a magical kungfu kingdom that they could escape into every now and then. But this kingdom is falling apart now, because he passed away on October 30, 2018, at the age of 94.

Have you ever seen snow? Many people in the world have not. Some countries never have snow; some have only a little on the tops of very high mountains. In the north of England, there is quite a lot of snow every winter, but in the south of England, there is usually little. When a student from a warm country comes to England in autumn for the first time, he feels cold at first. There are often dark clouds, grey sky and cold rain in England in autumn, and most students from warm countries do not like this.
But snow is different. Though it is cold, it is also beautiful. Perhaps, after several dark mornings, the student wakes up one day, and there is a lot of light in his room. He thinks "Is it so late?"and jumps out of bed. But no, it is not very late. He looks out of the window and there is the snow on the ground and on the houses and everywhere. The light of his room comes from clean, beautiful snow.

   When you are curious about something and want to know more about it, you can use the way of asking questions. Asking questions is the first step to make discoveries and find interesting answers. The following steps can guide you during the research.
   Step 1 Write down the subject that you are interested in on a piece of paper. Just get the main idea down. For example, you might write:
Discover more about robots.
   Step 2 Stop and think for a moment about what you have already known about your subject. List what you have already known like the sentences below:
   1. The first robot appeared in the USA in 1959.
   2. A robot can do housework and act as a teacher.
   3. Sometimes a robot catches viruses and causes a lot of problems.
   Step 3 What can you do with what you want to learn? By asking questions, start writing down questions about the robots on the paper:
   1. What might robots be like in the future?
   2. What other things can robots do for people?
   3. What kind of power will robots possibly use in five years?
   Step 4 Armed with your list of questions, you can now go to the nearest library or computer to begin your research. As you learn more about your subject, you'll probably discover some new questions.
   For example, you might discover that robots can help scientists explore dangerous places, like the sea and outer space. How? What happened? Asking new questions can help you research your subject more widely.
   The next time you find something interesting to research, take time to organize your thinking by asking good questions. And remember that learning more always brings more questions.

   Want to stay away from colds? Put on a happy face.
   Compared to unhappy people, those who are cheerful and relaxed are less likely to suffer from colds, according to a new study. It's possible that being happy helps the body fight illnesses, say the researchers from New York University.
   "It seems that positive feelings may reduce the danger of illness," said the study's chief researcher Sheldon Cohen.
In an earlier study, Cohen found that people who were cheerful and lively caught coughs and colds less often. People who showed feelings were also less likely to tell their doctors that they felt ill.
   In this study, Cohen's interviewed 193 adults every day for two weeks. During the interviews, the people were given colds by doctors and had to stay alone in a room for six days.
   The results showed that everyone in the study was equally likely to get ill. But for people who said they felt happy during the research period, their illness are less serious and lasted for a shorter time.
   Cohen believes that when people experience positive feelings, their body may produce a chemical that helps fight illness and disease. So if you are worried about your health, look on the bright side more often.

Dreams may be more important than sleep. Some people don't need much sleep. But we all need to dream, scientists say.

Dreams take up about one quarter of our sleeping time. People have several dreams each night. Dreams are like short films. They are usually in color. Some dreams are like old films. They come to us over and over again. That may be because the dreamer is worrying about something. Dreaming may be a way of trying to find an answer.

Some people get new ideas about their work from dreams. They could have been thinking about their work all day. These thoughts can carry over into dream. Sometimes we wake up with a good feeling from a dream. But often we can't remember the dream.

Dreams can disappear quickly from memory. Too much dreaming can be harmful. The more we sleep, the longer we dream. The mind is hard at working when we dream. That is why we may have a long sleep and still wake up tired.

Many children spend a lot of time watching or playing with electronic media –from televisions to video games, computers and other devices（设备）.

So, it is natural that parents should wonder about the time children spend looking at a TV or computer screen. Americans say “screen time” when they talk about any time children spend in front of an electronic device.

Perhaps parents can stop worrying so much about screen time, at least for older boys and girls. In October 2016, the American Academy of Pediatrics (AAP) listed several suggestions for parents and child care workers. Here are some of the suggestions.

●Avoid digital media use in children younger than 18 to 24 months.

●For children aged 18-24 months, avoid letting the child watch media alone. And avoid using media as a way to comfort your child.

●For children two to five years of age, allow one-hour screen time on “high-quality（质量）programming” a day and watch it with your child.

●For children aged 6 and older, don't spend too much time using media. Also, make sure that screen time does not take the place of healthy sleep, exercising, doing homework and other activities.

●Make sure to have media-free time together as a family, such as dinner or driving. Also make some areas of the home media-free. Turn off you child's electronic devices an hour before bedtime.

Some primary schoolchildren have been raised in homes with more green space around. They are likely to come with larger volumes of white and grey matter in certain areas of the brain. These differences are associated(关联) with beneficial effects on cognitive function (认知功能). This is the main conclusion of a study led by the Barcelona Institute for Global Health.

The study was performed among 253 schoolchildren in Spain .Lifelong exposure(接触) to green space in the living places was recorded—using the information on the children's addresses from birth up through to the time of the study. Brain structure was studied using 3D magnetic resonance imaging (MRI). Working memory and inattentiveness(注意力不集中)were graded with computers.

“This is the first study that shows the association between long-term exposure to green space and brain structure.” Says Dr. Payam Dadvand, the leading researcher of the study, “Our findings suggest that exposure to green space early in life could result in beneficial structural changes in the brain.”

The findings show that long-term exposure to greenness is positively associated with white and grey matter volumes in several parts of the brain. Some of them are related to higher scores on cognitive tests. Moreover, larger volumes of white and grey matter in those parts might lead to better working memory and less inattentiveness.

Exposure to nature has been thought to be necessary for brain development in children. Another study of 2,593 children shows that children in school with more green space have a greater increase in working memory and a greater decrease in inattentiveness.

Humans are believed to be tied to nature. Playing in greener areas offers children opportunities to search and learn. Accordingly, green space is thought to prompt important exercises in discovery, creativity and risk taking. These exercises in turn positively influence brain development.

Dr. Dadvand's study suggests how such structural changes could bring about the beneficial effects of green spaces on cognitive development, it also adds to the proof that suggests the lasting effects of early life exposure to greenness on our health and the benefits of increasing greenness in cities.

Further studies are needed to prove the findings in other populations, settings and climates. And researchers need to examine differences according to the nature and quality of green space.
