In a cold winter, a couple had to move out from the luxury (豪华的) house because of bankruptcy（破产）. The husband worked day and night to support the family but with no care of his wife. So she thought, "He doesn't love me any more. He just cares about his business ...... not me".

    One day, she began to take a bath, but he stopped her at the door, "Let me take it first, okay?"

    "Why not let me shower first," she asked.

    "I was tired, sweetie! You take it later, okay?" She was totally discouraged. (泄气的)

    On a tiring day, she found nothing to do and turned on his computer, a few words blurred(使……模糊)her eyes. It was his diary:

    Today, I was quite sad. She asked me why I was always taking the bath first, and I said to her that I was tired out. She was unhappy, in her mind, to think I treated her not as well as usual. But what can I do? I was not as rich as before! We moved to the small apartment, and there was only a shower in the bathroom. It was so cold to take a shower in such a freezing winter. But I found that if one person took the shower first, the room could get warmer, so every time I rushed to the bathroom first. I was thinking that, when she took the shower, the room would get warmer, at least 1℃, 2℃ or 3℃. Now I can't give her comfortable life, bring her the luxury restaurant, buy expensive dresses for her, but at least, I can give her 1℃ love.

    After reading the diary, the wife was deeply moved.

    Many people do the same things on their birthday: They have a big cake with lots of candles(蜡烛), and listen to their friends and family sing "Happy Birthday to You".    ①     would you like to pay money to sing that song?

    "I never thought the song was owned(拥有) by anyone," Nelson said in the e-mail to the New York Times.

    Some experts(专家) said that nobody knew who wrote "Happy Birthday to You". They also said there was no way to know    ④    people began to sing the song. But they believed(相信) people started to sing it long before the company began to own ⑤it.

    195 countries reached an agreement(协议) on Dec. 12, 2015 after two weeks' talks in Paris. They talked about climate(气候) change. It is the first time in history that most of the world's countries, rich or poor, promised to take action to deal with climate problems.

    Below is a chart showing where the greenhouse gas(温室气体) comes from.

Where is greenhouse gas from?

    The Paris Agreement(巴黎协定) sets up a goal of cutting down the earth temperature to less than 2℃. If the warming gets above 2℃， there will be serious problems on the earth like natural disasters.

The agreement also asks countries to volunteer to do things. For developed countries, they will do even more. They have a plan to offer over 100 billion dollars to help poorer countries to develop clean energy like water and wind power.

    However, the Paris Agreement won't solve earth warming by itself. The future also depends on how well each country will carry out their promises.

    Many people seem to know well about the rain forests. Some people even go to the rain forests to spend some of their time trying to make friends with the plants and animals there. The scientists are actually hard at work studying the plants that grow in the very top level of a rain forest. Rain forests are one of the richest environments on Earth. They are home to millions of species of plants and animals. The red research raft provides scientists with a platform from which to study life in the treetops. Scientists can even sleep on the raft, so they can stay up in the treetops for days at a time.

    Rain forests cover only about 6 percent of Earth's land surface. However, they contain more than half of the plant species on Earth. Many of these plants provide useful medicines to use against human diseases. In fact, about 25 percent of prescription medicines in the United States are based on chemicals from rain forest plants. Scientists think that many new medicines might be developed from plants that are yet to be discovered.

    Unluckily, rain forests are disappearing. Rain forest trees are being cut down for wood. Huge chunks of the forests are cleared to provide land for farm animals and crops. Scientists haven't identified all the plants in these forests yet. Some scientists think thousands of kinds of plants that we'll never even know about are being destroyed each year.
