Today, after finishing dinner in town, my husband and I were driving back home. As we pulled over, we saw a couple painting their furniture.

    I went inside our home, {#blank#}1{#/blank#} (change) and then went back out again to ask our neighbors if they needed any help. While leaving my home, I was plagued (困扰) by thoughts of {#blank#}2{#/blank#} (embarrass), denial, or being received. {#blank#}3{#/blank#}, I gathered the courage to go down and ask {#blank#}4{#/blank#} ,anyway!

    Initially, the woman denied. Then, the man said, “Sure”, and he handed me a spray paint bottle. We got into some good conversations {#blank#}5{#/blank#} painting with great effort.  When we finished, I briefly chatted with them before leaving.

    In the end, not only {#blank#}6{#/blank#} I enjoy helping them, but also learned about my neighbors. {#blank#}7{#/blank#} the way home, I must admit, I couldn't help but wonder {#blank#}8{#/blank#} they might be thinking about me.  {#blank#}9{#/blank#} is tough to do a good deed for others and not expect that they will be thinking good about you.

    Today's experience taught me some  {#blank#}10{#/blank#} (value) lessons in my life! Hopefully, these lessons will help me continue my acts of kindness in future.

    Today so many people are talking about AIDS, for which, {#blank#}1{#/blank#} (fortunate)，there is no cure now. When we talk about its influence on our society, this disease is {#blank#}2{#/blank#} most severe public health problem of all that we are facing in the 21^st century. It is spreading at a(n) {#blank#}3{#/blank#} (surprise) speed, especially in Africa.

    The UN AIDS organizations have come to the {#blank#}4{#/blank#} (conclude) that in the past 20 years, 20 million people have died of AIDS. And this figure will be three times bigger in the next two decades {#blank#}5{#/blank#} measures are taken in poor countries. Only if people change their basic behavior in time, can AIDS {#blank#}6{#/blank#} (stop) from spreading. For example, in San Francisco, the rate fell greatly when a serious program was carried out. People were {#blank#}7{#/blank#} (please) to change their behavior when they realized how serious a risk they were taking.

    Experts think in order to get the message across to those {#blank#}8{#/blank#} don't realize the seriousness of AIDS, a well {#blank#}9{#/blank#} (design) educational campaign is the only thing at the moment that can help. It would be criminal not to put it into practice. So everyone has a share of responsibility in the fight {#blank#}10{#/blank#}AIDS.

    Once there lived a rich man, {#blank#}1{#/blank#} wanted to do something for the people of his town. But first he wanted to find out {#blank#}2{#/blank#}they deserved his help.

    In the center of the main road into the town, he placed {#blank#}3{#/blank#} very large stone. Then he {#blank#}4{#/blank#} (hide) behind a tree and waited. Soon an old man came along with his cow.

    “Who put this stone in the center of the road？” said the old man，but he did not try to remove the stone. Instead, with some difficulty he passed around the stone and continued on his way. {#blank#}5{#/blank#} man came along and did the same thing; then another came, and another. All of them complained about the stone but not tried to remove {#blank#}6{#/blank#}. Late in the afternoon a young man came along. He saw the stone，{#blank#}7{#/blank#} (say) to himself: “The night will be very dark. Some {#blank#}8{#/blank#} (neighbor) will come along later in the dark and will fall against the stone.”

    Then he began to move the stone. He pushed and pulled with all his {#blank#}9{#/blank#} (strong) to move it，only to find a bag of money under the stone. Imagine {#blank#}10{#/blank#} surprised he was!

    Earth Day is an event {#blank#}1{#/blank#} (annual) celebrated on April 22.{#blank#}2{#/blank#} (found) by Senator Gaylord Nelson, an American politician and environmentalist, it was originally aimed at helping the public to know the current situation of pollution and {#blank#}3{#/blank#} (get) people to care about the earth.

    In 1962, Rachel Carson's bestseller “Silent Spring” created an {#blank#}4{#/blank#} (aware) of the dangerous effects of pesticides(农药）. Then, a fire,{#blank#}5{#/blank#}broke out in 1969 on Cleveland's Guyahoga River, revealed the problem of chemical pollution in water. Senator Gaylord Nelson dreamed of{#blank#}6{#/blank#}similar event that would get people to take environmental issues seriously. In 1969, he was inspired by protests against the Vietnam War and came up with the idea for Earth Day.

    In the fall of 1969, Nelson announced it and appealed to the entire country to get involved. Consequently, telegrams, letters and telephone calls {#blank#}7{#/blank#} all over the country poured in. Since 1970, Earth Day celebrations have grown. Later, Nelson{#blank#}8{#/blank#}(award) the Presidential Medal of Freedom because of his work.

    Today, numerous communities celebrate Earth Week, an entire week of{#blank#}9{#/blank#}(activity) focused on the environmental issues. In 2017, the March for Science {#blank#}10{#/blank#}(occur) on Earth Day and was followed by the People's Climate Mobilization on April 29.

    Diets have changed in China — and so too has its top crop. Since 2011, the country {#blank#}1{#/blank#}(grow) more corn than rice. Corn production has jumped nearly 125 percent over {#blank#}2{#/blank#} past 25 years, while rice has increased only 7 percent.

    A taste for meat is {#blank#}3{#/blank#} (actual) behind the change: An important part of its corn is used to feed chickens, pigs, and cattle. Another reason for corn's rise: The government encourages farmers to grow corn instead of rice {#blank#}4{#/blank#} (improve) water quality. Corn uses less water {#blank#}5{#/blank#} rice and creates less fertilizer(化肥) runoff. This switch has decreased {#blank#}6{#/blank#} (pollute) in the country's major lakes and reservoirs and made drinking water safer for people.

    According to the World Bank, China accounts for about 30 percent of total {#blank#}7{#/blank#} (globe)fertilizer consumption. The Chinese Ministry of Agriculture finds that between 2005—when the government {#blank#}8{#/blank#} (start) a soil-testing program {#blank#}9{#/blank#} gives specific fertilizer recommendations to farmers - and 2011, fertilizer use dropped by 7.7 million tons. That prevented the emission(排放) of 51.8 million tons of carbon dioxide. China's approach to protecting its environment while {#blank#}10{#/blank#} (feed) its citizens "offers useful lessons for agriculture and food policymakers worldwide." says the bank's Juergen Voegele.
