Aesop (伊索) was a slave living around 550 BC. We call the stories he wrote fables, as every story has a moral. Almost all the fables he wrote are {#blank#}1{#/blank#} (humor) and entertaining, appealing to people {#blank#}2{#/blank#} all ages. Till now, Aesop's fables {#blank#}3{#/blank#} (translate) into many languages and are known all over the world. Not only {#blank#}4{#/blank#} the fables themselves lived for nearly 1500 years, but the {#blank#}5{#/blank#} (express) from them have entered various languages.

    One fable, for instance, is about a farmer who was driving his cart along a country road. The cart got {#blank#}6{#/blank#} (stick) in the mud, but the farmer made {#blank#}7{#/blank#} effort to get it out. Instead, he began to pray to the gods for help. The god Hercules finally appeared and told {#blank#}8{#/blank#} man to get busy and push {#blank#}9{#/blank#}. “Push your shoulder to the wheel.” Hercules advised.

    The moral of the story is clear. We mustn't rely on others for help. Another saying which has come from the fable is “God helps those {#blank#}10{#/blank#} help themselves.”

    {#blank#}1{#/blank#}(see) from outer space, Earth is a blue planet, due to the fact that the ocean covers over 70 percent of its surface. According to a new study published in the journal Science, the ocean plays a great role in {#blank#}2{#/blank#}(slow)down global warming. It is" {#blank#}3{#/blank#}important buffer(缓冲物)", {#blank#}4{#/blank#}The New York Times put it.

    The oceans can absorb 93 percent of the heat trapped by the greenhouse gases {#blank#}5{#/blank#}humans release into the atmosphere. And the other 7 percent {#blank#}6{#/blank#}(absorb)by the air, land and ice caps, according to the Guardian.

    "If the ocean wasn't absorbing as much heat, the surface of the land would heat up much {#blank#}7{#/blank#} (fast) than it is right now," said professor Malin L. Pinsky at Rutgers University in the US. "In fact, the ocean is saving us from rapid warming right now."

    However, the ocean itself, as Discover Magazine noted, is heating up 40 percent faster on average than the United Nations {#blank#}8{#/blank#}(believe) five years ago. That means if the ocean temperatures increase {#blank#}9{#/blank#} this speed, the high water temperatures "will kill off marine ecosystems, raise sea {#blank#}10{#/blank#} (level) and make hurricanes more destructive (破坏性的)", the Guardian reported.
