    We are lucky to live in a rich country where we have many things. However, most of us usually1some things.

    Electricity（电） is one thing that we waste2 Lights, TVs,3and other things are often kept on even when no one is using them. We should turn them off when we do not need them. It4less than a second to do it. Anyhow, not wasting electricity is saving money, because we do not have to5the electricity we do not use.

    The second thing that we often waste is water. Fresh water is precious（宝贵的）,6it shouldn't be wasted. It is only a simple matter of turning off a tap. I am sure7can do this easily if he wants to.

    8big waste is food. My mother9cook so much food that much of it was thrown away. I told her we had wasted so much10. She thought I was right and now 11cooks what we can eat.

    It is not12to be wasteful. I find there is a simple13of not wasting things. That is to use only what we14. Do not touch what we do not need15this way we can stop being wasteful.

    An important question about eating out is who pays for the meal. If a friend of yours asks you to have lunch with him, you may say something like this, "I'm afraid it'll have to be someplace cheap, as I have very little money." The other person may say, "OK, I'll meet you at McDonald's."

    This means that the two agree to go Dutch, that is, each person pays for himself. He may also say, "Oh, no. I want to take you to lunch at Smith's," or "I want you to try the Chinese dumplings there. They're great." This means the person wants to pay for both of you. If you feel friendly towards this person, you can go with him and you needn't pay for the meal. You may just say, "Thank you. That would be very nice."

    American customs (1) about who pays for dates (2) are much the same as in other parts of the world. In the old days, American women wanted men to pay for all the meals. But, today, a university (3) girl or a woman in business world will usually pay her way during the day. If a man asks her for a dance outside the working hours, it means "Come, as my guest (4)." So as you can see, it is a polite thing to make the question clear at the very beginning.

    In earliest times, men considered lightning to be one of the great mysteries (神秘的事物) of nature. Some ancient peoples believed that lightning and thunder were the weapons (武器) of the gods.

    In reality, lightning is a flow of electricity formed high above the earth. A single flash of lightning 1.6 kilometres long has enough electricity to light one million light bulbs (灯泡).

    The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752. In the same year he also built the first lightning rod (避雷针). This device (装置物) protects buildings from being damaged by lightning.

    Modern science has discovered that one stroke (闪击) of lightning has a voltage (电压) of more than 15 million volts (伏特). A flash of lightning between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second.

    Scientists judge that there are about 2,000 million flashes of lightning per year. Lightning hits the Empire State Building in New York City 30 to 48 times a year. In the United States alone it kills an average (平均数) of one person every day.

    The safest place to be in case of an electrical storm is in a closed car. Outside, one should go to low ground and not get under trees. Also, one should stay out of water and away from metal fences. Inside a house, people should avoid open doorways and windows and not touch wires or metal things.

    With lightning, it is better to be safe than sorry?

    Here is a story: A man sees a butterfly(蝴蝶). The butterfly tries to get out of its chrysalis(蛹). Feeling sorry for it, the man decides to help. He cuts the chrysalis and the butterfly comes out easily. Surprisingly enough, the butterfly is unable to fly. If the butterfly doesn't struggle(挣扎；奋斗) to leave the chrysalis, it can't fly! The struggle develops the energy in the butterfly which makes it fly. Similarly, the challenges of life bring out the best in young people and make the fly.

    When people are young, meeting and overcoming challenges will make them strong and ready to face life. When we look at successful people, we see that the most successful of them are people who have had to struggle. One famous businessman, who now owns many big supermarkets, used to carry clothes on his back and sell them from door to door when he was young. Another successful man is Dennis. His father died when he was only twenty. His father's death forced him to mature fast. He had to bring up a family of nine people. He took up the challenges and overcame them. Today his brothers and sisters are leading successful lives.

    Sometimes challenges do not appear to us because we keep away from them. So some parents and teachers actively encourage young people to face challenges. They might organize some activities for young people which provide them with challenges, like rock-climbing, camping, volunteer work and so on. However, just passing exams will not prepare a person for life. We must meet and overcome challenges. The young people of today will become the leaders of tomorrow. For countries to continue to become successful, it is important that the young people learn to meet challenges and overcome them.

    Look! Students are learning folk        at school. They are       a middle school in Nanshan. The school has offered folk art classes since 2016. It invites artists to teach students embroidery (刺绣)and pyrograph (烙画). Pyrograph is a kind of art in which the artist draws on pieces of wood or       objects by using burn marks. Students        use gourds (葫芦)for their pyrography classes. The classes can help students learn more about Chinese traditional folk art and pass        on.

    We        in about two months. I think it is a good chance for me to say thanks to our school, all the teachers and classmates. Our school is very beautiful. I        my happiest time here since we came to this school. At school we aren't        to break the school rules. I have met so many good teachers in my school life. They are all very kind. But now I only want       you something about my English teacher in Grade Seven. She was very strict with us but also patient. At that time, I had so many problems learning English that I wanted to give up English. My English teacher always      me a lot. She helped me with my problems. Besides, she often talked with me about the ways of learning English. I'll remember her forever.

    I have a cold. I feel very tired. My throat is sore, I have a cough and my head hurts. Last night,       . The fever made my body feel hot. I really don't like being sick, because I can't go to school. And my friends can't visit me, either.       .

    There is no cure（治疗）for the common cold. Below are three ways to help stop a cold spreading and to feel better again.

    First, wash your hands. Washing your hands is the most important way to stop the spread of colds. Cold germs(细菌）are spread by touch.       . So if we wash hands carefully using soap and hot water. We won't get the cold easily.

       There is a saying that "coughs and sneezes spread illness". Always use a handkerchief(手帕) or napkin to cover your mouth when coughing and your nose when sneezing. That way, the germs won't get onto your hands and spread to things you touch such as doors, cups or plates.

    Finally, clean your house and take care of yourself. We can use a robot cleaner to clean our house on time. Be sure to use only your own toothbrush and cup……

          , but if you get worse, you should see a doctor at once. Eat healthy simple foods such as soup or rice. Get enough rest and sleep. Stay in bed, read a book, do your schoolwork or practice your English!

    Remember that a common cold only lasts a few days. You'll feel better soon.

A. Next, cover your nose and mouth

B. The germs(细菌) get on to your hands and from there into your eyes, nose and mouth

C. We should stay away from all kinds of colds

D. I also had a fever so I didn't sleep very well

E. Because if one of you gets a cold, often all of you get it

F. Some cold medicines can help stop fever and aches

G. I hope all of you'll get better soon
