    Farming in the USA today is very different from that 100 years ago. In those days, farmers did not have many machines to help them. They had animals. {#blank#}1{#/blank#}This meant that farms were smaller than they are now. Farmers also worked in a different way in the past. In those days, farmers grew fruits and vegetables and kept cows, pigs and chickens to feed their families. {#blank#}2{#/blank#}

    Farmers have a very special life in many ways. First of all, they can't leave the job at the end of the day. They live on the farm and there is always work to do. Second, a lot of farm work is outdoors, so the weather is very important for farmers. {#blank#}3{#/blank#} A lot of bad weather means farmers will lose money. Finally, farmers work with plants and animals. They understand nature better than other people do.

    {#blank#}4{#/blank#} Spring is a time for planting. Farmers are busy getting the fields ready and then planting the seeds(种子). In summer, farmers must take good care of the plants. Some may need water. Other plants may have problems with insects or diseases. Then in fall, the fruits or plants are ready for picking. {#blank#}5{#/blank#} Winter is a time for rest or for work on the farm machines.

A. Farm work changes with the seasons.

B. That is a very busy time for farmers.

C. But animals work slowly compared to machines.

D. It is also important for the success of their farms.

E. Today farmers grow things on the farms so they can sell them.

    The young woman at the airline check-in desk meant no harm. She greeted a customer with a question which would be no problem in Chinese," What's your problem?" But this question is impolite in English, and the customer became very angry. In this situation, the young woman should say." May I help you?" or" How can I help you?" Then she would not be facing an unhappy traveler.

    Maybe you would like something. Instead of saying" Giving me a hamburger," say," Could I have a hamburger, please?" or "I'd like a hamburger." English speakers often use the expressions" please "and" thank you". When requesting something, use" Can I" or "Could I". In formal situations," May I" is the best.

    {#blank#}3{#/blank#}

    When someone asks your opinion, you don't want to make them feel upset by saying something they think is unkind. Maybe someone asks," What do you think of my idea?" Don't say," It's a terrible idea." if you don't like it. Say," I don't think it's the best idea." Then people will accept your opinion more easily.

    {#blank#}4{#/blank#}

    When you can't accept an invitation, don't say." I can't. I'm busy" Refuse in a more indirect way." I'm afraid I can't…" or" I'd love to, but…" or" That sounds great, but..." These phrases soften the message and make it easier to accept.

    {#blank#}5{#/blank#}

    Avoid saying others have done wrong. Don't say," You don't understand me." Say, Maybe I need to make clear what I mean." Give special attention to" I" or" We" rather than" you". Take time to learn polite phrasing. Then you'll make your communication with people more pleasant.

    In 30 years from now, what will we eat? Will the food still be the same as it is now?

The United Nations says that there will be over 9 billion people in the world by 2050. Our food needs will grow by 70%. What we eat now may not be enough for humans in the future. That is to say, we'll have to turn to something else. But what else can we eat? Here are a few possible choices.

    Veggie (Vegetable) meat

    A new kind of hamburger is now popular in the US. It looks the same as any other hamburger, and so is the taste. But it's actually a "beef" burger made out of plants. The company behind the burger, Impossible Foods, uses peas and potatoes to make the "beef". They take coloring, protein (蛋白质) and fats from these plants and mix them together.

    Making meat out of plants uses less water and land than raising animals for meat. It also creates fewer green house gases. Some food companies are making chicken, pork and other meat out of plants, too-follow the same steps as making the "beef".

    Insects

    Insects take up little space and don't make much waste. They also have more protein than beef, chicken and pork. This makes insects another possible food of the future.

    It's common for people in some places to eat whole insects. But most people probably won't want to see the insects they eat. So in the future, people will first turn insects used for food into powder (粉末). Then they can use the powder to make other foods like chips, protein bars, biscuits and so on.

    Algae

    The BBC says algae farming could become the world's biggest farming industry in the future. They point out that algae is cheap and grows very quickly. Also, it's very nutritious (有营养的). It has much more protein and oil than many other plants.

    Besides eating algae as a dish on its own, people may also use algae oil and algae butter in the future. Some algae has a strong taste. The UK scientists are trying to use algae to take the place of salt.

    CCTV reported that every year Chinese people throw away a lot of food which can feed 200 million people for a year.

    Do we have too much food? Of course not. According to the UN World Food Programmed, there were 900 million hungry people all over the world in 2013.

    About six million children die of hunger every year.

    So think about it. We should say no to people who waste food every day. An old saying goes," Every grain on the plate comes from hard work. "It tells us everybody must save food.

    Luckily a number of people have realized the importance of saving food.

    Li Hong, a waitress in a restaurant in Jiangsu, once lost her Job because she took some leftover(剩余的) food home for her son. But many people were by her side and criticized(批评) the waste of food.

    What should we do in our daily life to stop wasting food? We can do many things to prevent it from happening. Here are some tips:

    Don't order too much food in a restaurant. Only order as much as you can eat. If you can't eat all the food you order, take the rest of it home.

    Don't be too picky(挑别的) about food. Some food may not be tasty, but your body needs it.

    Don't keep too much food at home, especially for fruit and vegetables.
