Chuck Wall teaches management and human relations at Bakersfield College. He walked into class one day and told his students that their homework was to perform a simple and random act of kindness. Not {#blank#}1{#/blank#} (understand) the homework, the students didn't know what to do. Chuck didn't answer their questions. {#blank#}2{#/blank#}, he encouraged his students to work it out by themselves.

    One week later, the students entered the classroom and began sharing their stories {#blank#}3{#/blank#} (excited). One reported on helping a poor dog {#blank#}4{#/blank#} (abandon) by its owner. Another student told others about giving blankets away to the homeless. Gradually, more and more students developed the habit of doing such kind acts, from {#blank#}5{#/blank#} they benefited a lot.

    Since then, similar kind acts {#blank#}6{#/blank#} (perform) in schools around the world. Many schools organize a Random Acts of Kindness Week, around November 13^th, {#blank#}7{#/blank#} (celebrate) World Kindness Day. Some schools use each day of Random Acts of Kindness Week to perform a {#blank#}8{#/blank#} (differ) kind act, such {#blank#}9{#/blank#} making a new friend, helping someone, doing community service or raising money for a charity. In this way, students learn to consider other people and think about how small actions can make the world a {#blank#}10{#/blank#} (good) place.

    If you go out to the fields at night in spring or summer, you can hear frogs singing{#blank#}1{#/blank#}(joy) here and there. It seems as if they were performing a field symphony（交响乐）.

    The frog is a good and useful creature that benefits human beings. They can catch fast-moving insects. Each frog eats a large number of pests that are {#blank#}2{#/blank#}(harm) to crops. This little creature is regarded {#blank#}3{#/blank#}“the natural enemy of pests”.

    {#blank#}4{#/blank#} now frogs are getting fewer and fewer. This is{#blank#}5{#/blank#}they are killed and put on the table as a delicious dish by their chief enemy, human beings. It is a shameless and cruel act, isn't it? Another reason responsible for the rapid reduction of frogs is {#blank#}6{#/blank#}farmers use insecticides (杀虫剂) to kill pests and frogs get {#blank#}7{#/blank#}(kill)as a result of drinking poisoned water or eating poison-killed insects.

    Something must be done without delay {#blank#}8{#/blank#}(save) frogs. If we don't punish those {#blank#}9{#/blank#}sell and kill frogs to make money, then one day all of us {#blank#}10{#/blank#}(punish) by nature for failing to keep the balance of nature.

    You might want to think twice before purchasing{#blank#}1{#/blank#}(conventional) grown strawberries or spinach(菠菜). According to a new report from the Environmental Working Group(EWG), these foods are the most likely{#blank#}2{#/blank#}(pollute) with the pesticide.

    Even low levels of pesticide exposure can be harmful to infants, babies and young children,{#blank#}3{#/blank#}parents and caregivers should take measures to lower children's exposures{#blank#}4{#/blank#}pesticides while still{#blank#}5{#/blank#}(feed) them diets rich in healthy fruits and vegetables.

    Just last year, the red berry knocked apples and{#blank#}6{#/blank#}(hold) the title of the most polluted. The pesticide increased in strawberries because of out-of-season demand. The most polluted strawberry had traces of 20{#blank#}7{#/blank#}(vary) pesticides.

    Also moving up on{#blank#}8{#/blank#}list this year is spinach. Spinach jumps from the{#blank#}9{#/blank#}(eight) to the second most polluted product. The study finds spinach samples contain more pesticides by weight than all other produce{#blank#}10{#/blank#}(test). In high doses, it can cause damage to the nervous system.

    Changes are hard for many people to accept. However, what's worth keeping in mind is that life is constantly changing. We might lose our jobs, lose our loved ones, or have other life-changing things, but these changes are just part of life. We might not like how society is changing or how our community is changing, but we need to be able to deal with these changes in a positive way. Luckily, there are many ways to view changes, to deal with them and to finally accept them.

To deal with changes wisely, you should accept that feeling when a type of change is upsetting you. There's no way you'll get past it if you ignore it and don't work through it. Thus, if you've lost your job, let yourself feel mad and/or disappointed. You can even express your feelings to others, but do so in a polite way. Also you can ask yourself, "Why am I upset or worried about this change?" Then, "What is it that I believe will happen, as a result of this change?" And then, "Are these thoughts and beliefs correct and practical?" Going through these questions can help you determine if the change is really worth worrying about. What's more, even though the change can have a negative effect on your life, in most situations you can use it to turn a loss into an opportunity or a way to rediscover your enthusiasm for life.

    Of course, when it comes to dealing with changes, taking action is more important. If you're going through a period in your life when the change is negatively influencing you, make yourself busy. Making yourself busy, by working, producing something or engaging socially with others, will do more than just make you forget worries–it'll help you contribute to changing your life positively for the future. Besides, you can try something you've never done before.

    An important part of accepting changes is finding a way to move on and thinking about your future. By looking ahead, you'll be able to better deal with the past and accept it as that had to happen in order to move forward. So accept the change that makes you uncomfortable, and determine you're going to try to use your energies to make an even better world. In this way, you're using it to power what you think is a positive change.

    "It was the most {#blank#}2{#/blank#} (eager) expected debut in the history of the national pastime," sports author Robert wrote. "It {#blank#}3{#/blank#}(represent) both the dream and the fear of equal opportunity, {#blank#}4{#/blank#} it would change forever the color of the game and the attitudes of Americans."

Just two years into the Major Leagues, Robinson won the National League Most Valuable Player Award. He'd go on to play in six World Series and helped give the Dodgers {#blank#}8{#/blank#} World Series win in 1955.

    Off the field, Robinson was a forefather of the Civil Rights Movement, speaking out against {#blank#}9{#/blank#} (race) discrimination and {#blank#}10{#/blank#} (push) baseball to use its economic influence to fight against racialism.
