Mr. White lived in the country. One day, he bought a second-class train ticket and went to London to buy something. All the seats in the second-class carriages had been taken when Mr. White got on the train. {#blank#}1{#/blank#}

    Half an hour later, {#blank#}2{#/blank#} So he went into one of them and took an empty seat. The other four men seemed to be rich people because they all wore fine clothes. But just before the train started, a different kind of person jumped in and sat down.{#blank#}3{#/blank#} It was clear that he was very poor.

    Everyone in the carriage looked unhappy with the young man. Mr. White thought that he would not be the only person to pay more. {#blank#}4{#/blank#}If so, he was wrong. For when the train had traveled an hour, the door opened and the ticket-collector came into the carriage. Of course, Mr. White had to pay more money for his ticket. But to his great surprise, one by one each of the four men held out a second-class ticket. {#blank#}5{#/blank#} He was the only man who had the first-class ticket in the carriage.

    Do you clean your school desks every day? If not, then maybe it's about the time for you to get started. Keyboards, computer mice and telephone dials are infected (polluted) with lots of germs(细菌), according to scientists from the University of Arizona, the US.

    The study suggests that office equipment should be regularly cleaned. “Desks are in fact germs' cafeterias(自助餐厅),” said Charles Garbage, a biologist who took part in the study. “They are breakfast bars, lunch tables and everything else.” The desks at your school are probably not different.

    The scientists found that telephones in workplaces have almost 4,000 germs/cm², keyboards 500 and computer mice around 250. The office as a whole contains 4, 750germs/cm².

    When some people catch a cold or flu, they leave germs on the surfaces(表面) they touch during the day. Some flu germs can live on the surface for up to 72 hours, so the germs can easily move to other people. If you're ever wondered why everyone catches the germs when only one student has a cold, now you know the answer.

    Experts in the US last month warned about the spread(传播) of the germs during flu seasons. They reminded Americans to cover their noses and mouths while sneezing, often wash their hands and clean their office desks.

Hand washing is the most important. Killing germs during hand washing is useful only if you clean carefully with soap and water for at least 30 seconds. You should pay close attention to cleaning your thumbs, fingertips and fingernails.

    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.

    I am Canadian. I started learning French when I was 10 years old. But my whole experience with the language was in the classroom. All of that changed, however, during my last summer of high school. As a 17-year-old girl, I flew across the country by myself for the first time! I headed for Quebec to live in the province with a French-speaking host family, who didn't speak any English. And I would learn French at a local school.

    On the first day of school, all of us students were given a test to determine (测定) our language level. We were required to speak only French all summer.

    I made every effort to communicate in a second language by making new friends, seeing movies and even ordering food from restaurants in French. Though I couldn't understand most of it at the very beginning, the whole experience was exciting and refreshing.

    On weekends, my classmates and I took trips to different places around the province. On one trip, we went whale watching on the St. Lawrence River. Even though it was raining, we could see huge whales swimming around our boat. The most memorable part of our trip was a visit to historic Quebec City. I walked along the stone streets, took pictures of the European-style (欧式的) buildings, and learned some stories there.

    Finally my efforts paid off! At the end of the summer, I was able to communicate pretty well. I couldn't wait to go back to school and talk with my French teacher. Being fully immersed (沉浸)in a French-speaking environment was a valuable learning experience. And it could be the main reason for my improvement in French.
