A new report says plastics are responsible for $13 billion in damage to the oceans and the undersea environment. The findings were announced recently at a United Nations conference．{#blank#}1{#/blank#}.

    Plastic thrown away carelessly makes its way into rivers and other waterways.{#blank#}2{#/blank#}. After a while, it collects in the sea. And plastic never goes away. Plastic is not biodegradable—destroyed by bacteria or natural processes. Instead, it just breaks up into smaller pieces over time. The oceans contain a lot of chemicals and other pollutants(污染物).{#blank#}3{#/blank#}.That means harmful material may get into our food supply.

    {#blank#}4{#/blank#}. Human beings cause pollution and they can take steps to stop it. They can use fewer single use product containers and throw plastics away correctly. Plastic recycling programs also works—where old bottles and other plastics are collected, broken down and used to make new products. We could reuse bottles in our households many times if we wish to, rather than end it after the first use. We could, when we get rid of that plastic, recycle it and reuse it, which replaces the need for raw materials.

    The report also calls on companies to improve methods for using plastics.{#blank#}5{#/blank#}. And it calls for information about the way plastic is thrown out or removed from use. By putting a new value on plastic, industry has a special reason to clean up the environment.

    But all of the companies must join to deal with the problem.

A. Then, fish may eat the plastics.

B. But people can make a big difference.

C. Plastics should be gathered together and reused.

D. It is convenient to use plastic bags in everyday life.

E. It asks for them to better measure and control plastic use.

F. The plastic eventually reaches coastal areas and ocean waters.

G. The report tells about harm to sea life and what might be done to improve the situation.

    A man had a dream in which he was told where he could find fantastic wealth in a remote place. When he awoke, he immediately set off to find it. After a long journey full of danger and hardship, he arrived at the place in his dream. A local man who had heard about the dreamer's purpose laughed loud and long, saying that he had dreamed three times about a house where great treasure was buried under a fountain. It made the dreamer realize that the place the local was describing was his very own yard. He returned home and found the treasure.

    Like the man in this tale, the Chinese movie industry has been on a long journey to find its place in the world. In 1994, “The Fugitive” became the first major Hollywood film to be shown in the country in decades. Audiences were attracted by the movie's fast pace and sound effects, and it proved to be a great success. Since then, the Chinese film industry has balanced a complex (复杂的) relationship with Hollywood.

    Although there has been a sharp slowdown in China's box-office numbers—movie-ticket revenue rose just 3.7 percent in 2017 after growing by an average of 35 percent per year from 2011 to 2016~the country still has a huge movie market, with theaters continuing to expand into more rural areas and audiences proving that they have a strong desire for Hollywood action films. So much so that recently, Hollywood has even started to make movies with China in mind, casting Chinese movie stars with great box-office power and changing the plots of films to win over Chinese moviegoers.

    Many in China's film industry, from young scriptwriters (编剧) to senior critics, know Hollywood's dramatic structure all too well and support its styles. And many American offerings introduced in the Chinese market, regardless of quality, continue to do well among Chinese audiences, especially with young people, whose tastes and viewing habits have been shaped by Hollywood movies and TV shows. Like audiences in other developing countries, those in China tend to have a worldview filtered (过滤) by and focused on the United States, even though the United States doesn't mean the whole world and Hollywood isn't the world's only movie industry.

    Like an ocean that refuses no rivers, China's movie industry will continue to influence and allow itself to be influenced by its international counterparts (对应的人或物). China needs the United States, and the United States needs China. But at the moment, a large difference exists in that very few Chinese movies are able to enter the American market and attract a significant audience. Chinese audiences provide Hollywood with huge profits, but what does China's film industry gain in return?

    What is the easiest way to stay warm in the super cold?{#blank#}1{#/blank#}. At least that is what Santa Claus told me.

    During Christmas, Dennis and I went to Finland. We brought back some tips for keeping warm in a cold temperature.

    ⒈There layers(层)work wonders.

    Start with the base layer, which sits right on your skin: choose something that can absorb sweat{#blank#}2{#/blank#}A sweater is a good choice. The most important layer is the outer clothes, which should be waterproof(防水的)and windproof.

    ⒉{#blank#}3{#/blank#}.

    You lose heat from every millimeter of uncovered skin, which was the biggest lesson I learned on this trip. My whole body was well covered. But I missed one sport: my face. So it often felt like the wind was going to blow my nose off.

    ⒊Exercise, don't just stand still.

    When it's cold, exercising may be the last thing you feel like doing, but be smart.{#blank#}4{#/blank#}and you will feel the difference. When we first got to Finland, we were freezing. But after a couple of minutes jumping around, we felt less cold.

    ⒋If you have a heater

    You may want to turn it all the way up, but it's best to keep it at between 18 and 20 degrees{#blank#}5{#/blank#}but not create a huge difference between inside and outside.

A. Grow a crazy beard.

B. The key is what your layer is

C. Cover every bit of your skin

D. That will keep you comfortable

E. Take a walk, faster than your normal speed

F. Don't forget to keep your hands and feet warm, too

G. The middle layer keeps your body heat from getting away

    These days, tall modern buildings are everywhere. But if you want to see how life was back in the old days, China still has many beautiful water towns to visit. And now, CNN has chosen five of the country's most beautiful ones.

    The village of Zhouzhuang in Jiangsu calls itself the “oldest water town in China”. The village was built in 1086and is crossed with canals. Taking a boat ride through town, the red lanterns might make you think of China's romantic past.

Hongcun in Anhui is 900 years old. It was built to look like a big ox. Huangshan Mountain is the head; the town is the body and the bridges are legs. Hongcun is filled with lakes and beautiful Anhui-style buildings.

    Fenghuang in Hunan doesn't look like a bird, but its name means “phoenix” in Chinese. The town is really as beautiful as the mythical bird. The stilted buildings on each side of the Tuojiang River make the area look like a scene from a postcard.

    Huangyao in Guangxi is known for its natural fengshui. The town lies in a river bend. People say it can prevent the villagers' good fortune from flowing away

    While most water towns are in the south, Shangdong's Tai'erzhuang stands out in the north. The town lies on the bank of the Beijing-Hangzhou Grand Canal. It was a busy trading center during the Ming and Qing dynasties. In the town, there are ancient bridges, a canal and temples, making you think of its past glory.

    In cooperation with German experts, several scientists from the University of Bradford believe that they finally solved a mystery that has been confusing millions of people: why our hair turns gray with age.

    The researchers came up with their results by examining native hair and cells from human hair follicles（毛囊）. They say the secret turns out to be hidden in catalase（过氧化氢酶）, which is causing hair to turn gray.

    Catalase production goes down with age and stress, allowing hydrogen peroxide（过氧化氢） in the hair to do its favorite job—making hair gray, and then white, by blocking the normal production of melanin（黑色素）. Melanin is our hair's natural pigment that is responsible for the color of hair. It also determines the color of our eyes and skin.

    Dr. Gerald Weizmann, an editor of a journal, says," All of our hair cells make a tiny bit of hydrogen peroxide, but as we get older, this little bit becomes quite a lot, and our hair turns gray and then white."

    The new study brings hope for millions of people who have to color their hair: to finally obtain some shampoo that will decrease levels of hydrogen peroxide and therefore restore gray or white hair to its natural color or even prevent it from turning gray.

    The researchers are already conducting an experiment with such a drug on a few volunteers with gray hair and expect to get the results in the next two to three months. If everything works out, millions of people will choose between this drug and other previously used expensive dyes. However, even if the drug works, it will take at least several years before it can be brought to the market.

Most parents are worried the first time they catch their kids out in a lie. According to child and teen psychiatrist Gayani DeSilva, lying can actually be a sign of healthy development in young children. "Kids lie for many reasons, and much of it is normal," DeSilva says. "People are not born with the knowledge of communicating with others and getting their needs met. They'll experiment with different communication styles and techniques until they find the ones that work best for them. Lying is one of those techniques."

As kids get older, they become more aware of how their actions affect others, and many will lie less frequently. In spite of this, parents still need to Lead their kids to form a habit of not lying. According to DeSilva, when children lie, look at them directly and ask what they need. After they tell you, gently remind them that telling you directly will be more effective than lying.

It's also a good idea to model the behavior you want to see in your kids. In other words, don't lie to your children. This will set you and your children on a course of open communication and trust.In some cases, lying is a sign of a deeper issue. A child who is neglected will lie more than a child who has attentive and responsive parents. He's not sure whether he's loved. He may lie to please others. The same goes for a child who has experienced something unpleasant. He may lie to try to hide his shame, avoid admitting his needs, or to control his surroundings to ensure his safety.

By paying attention to the reasons behind a lie, parents can figure out what need to be done. For example, while Jack might lie about completing his homework in order to play video games, he also might be trying to avoid negative feelings connected with school work, and this is just where parents should start, says therapist Gideon Javna.
