For many people, history classes are seen as no more than requirements for getting degrees in chemistry, biology, business, marketing, etc. {#blank#}1{#/blank#}． Below are a few reasons why it's vital that today's people continue to learn about the past.

    Understanding where people come from plays a key role in understanding who they are.{#blank#}2{#/blank#} For this reason, it's extremely important to learn history in order to understand why people are the way that they are.   

    Through history classes, you can experience a shift (改革) in the way you think. {#blank#}3{#/blank#}It's important to develop minds to be able to consider problems from different angles. Finally, this shift can improve your ability to analyze and understand situations, to make educated decisions and to learn how to weigh the consequences related to each choice before you.

    {#blank#}4{#/blank#}The idea that history repeats itself is rooted in truth. From wars to fashion to political trends, historians are often able to make predictions about the future based upon the past. By having a deep understanding of what happened in the past, today's people can better prepare for brighter futures by making the right decisions—instead of repeating old mistakes.

    Many people may not believe that a degree in history can lead to a well-paid job. In fact, students who graduate with degrees in history can become lawyers, business owners, think tank members, educators, leaders in historical organizations writers and so on. {#blank#}5{#/blank#}.

Happiness begins from appreciation

    If you are feeling that life just cannot be any worse for you, it can be challenging to think positive. When stressed, depressed, upset or otherwise in a negative state of mind because you are aware that misfortune keeps occurring, it is important to shift those negative thoughts to something positive. {#blank#}1{#/blank#}

    It is often very hard to think positive when so many things are negative, but be sure that someone, somewhere is worse off than you. {#blank#}2{#/blank#} If you start with one small, positive thing and appreciate it during the course of your day, you will begin to move into a more positive situation and people will start showing up in your life. With appreciation, you will find that over time, you will change your outlook and choose to be happy, regardless of the events around you. {#blank#}3{#/blank#}

    Begin and end each day with a “Thank you for this wonderful, glorious day!”

    When you see the rise of gas prices, say “I am so glad to have a vehicle in which to get around.”

    When your boss is too hard on you, say “I am grateful for my job as I know that many don't have one.”

    If you are having health problems, be grateful for what does work: “I really do appreciate it that my eyes see, my ears hear, my mouth tastes, my legs walk, my arms lift and my mind thinks and everything else works.”

    Write down what you're grateful for each day. In moments when you're feeling really down, read loud what you wrote previously. {#blank#}4{#/blank#} If you practice this regularly, you will find your list getting longer and longer.

Yellow Robot deliver snacks to your home

    A robot makes its way back to a supermarket after making a delivery during a demonstration in Beijing.

    Along a street on the outer edges of Beijing, a yellow and black cube about the size of a small washing machine moves leisurely to its destination. This “little yellow horse” is a delivery robot, transporting daily essentials like drinks, fruit and snacks from the local store to the residents. Equipped with GPS system, cameras and radar, the robot is seen by its creator as the future of logistics(物流) in China.

    “The weak point is that it can't deliver directly to the door like a human.” said one customer, who does not live on the ground floor. “But it is still quite practical. The robot delivers relatively quickly.”

    The robot takes off for Chinese customers' love of cashless payments and smartphone shopping. China is the world's biggest online shopping market with more than half of its population making at least one smartphone purchase per month, according to professional services firm PricewaterhouseCoopers. Whether buying electronics, toilet paper or clothes, Chinese customers are used to simply tapping a button on their smartphone and getting a home delivery.

    To get a delivery via the “little yellow horse”, customers select the desired products, tap in the address and pay via their phone. Then, the supermarket staff place the items in the robot.

    Liu Zhiyong, founder and CEO of Zhen Robotics, which manufactures the robot, sees a bright future for his creation. “At the moment, there are 100 million packages delivered every day in China. It will be one billion in the future,” Liu said. “ There will not be enough humans to make the deliveries. We need more and more robots to fill this gap and reduce costs.” These costs are especially high in the last kilometer of a delivery.

    Each year there is an increasing number of cars on roads and streets as millions of new cars and trucks are produced. One out of every six Americans work at putting together the parts of cars, driving trucks, building roads or filling cars and trucks with gas. {#blank#}1{#/blank#} Because most Americans find they are using their cars in almost every aspect of their life. {#blank#}2{#/blank#} The polluted air becomes poisonous and dangerous to health.

    {#blank#}3{#/blank#} That's what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.

Another way is to take the place of the car engine by something else.{#blank#}4{#/blank#} Many makers believe that it will take years to develop a practical model that pleases man.

To prevent the world from being polluted by cars, we'll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle. Bicycling is thought to help keep the air clean. But this change does not come easily. A large number of workers may find themselves without jobs if a car factory closes down.{#blank#}5{#/blank#}

    Although cars have led us to a better life, they have also brought us new problems.

A. Americans know cars very well.

B. Americans won't live without cars!

C. Inventors are now working on steam cars as well as electric cars.

D. However, the number of vehicles has continued to increase in recent years.

E. One way to get rid of the polluted air is to build a car that does not pollute.

F. Thus the problem of air pollution would become less important than that of unemployment.

G. However, some have realized the serious problems of the air pollution that is caused by cars.

    Some recent surveys show that the health conditions of many white collar employees and office workers are rather critical. Death cases among white collar employees and office workers are increasing year by year and these cases are generally believed to have been caused by overwork and spending little time taking rest or doing exercise.

    If their offices are within the distance of half an hour's walk, some office workers now choose to go to work on foot. Ms. Deng, who works in a foreign enterprise in Beijing, has been walking to her office for more than six months now. I usually have a tight work schedule and can't find time to do exercise. So I choose to walk to work. As she said, if the office is not far from home, most women would like to go to work on foot. Walking is good for their health and can help them to keep good figures as well.

    Apart from walking to office, one can also find time to do exercise when one is at work. The simplest way is to abandon the lift. Mr. Wei, who works in the Passenger Service Department at Shenzhen Airlines, is one of such men who frequently climb stairs to his office. I only use the lift whenever I'm with my colleagues or my boss. Otherwise, I would climb stairs instead of taking the lift.

    In addition, some office workers try to find time to go to a gym at the end of a day. Ms. Sang works in a law firm in Shenzhen. She goes to the gym several times a week when she has the time. I go to the gym every weekend. During the weekdays, I will also go there whenever I have the time. Ms. Sang and her husband both have a gym membership card for a whole year. The cards cost them 3, 000 yuan. However they think it's worth it.
