Running a few kilometers each day is good for our health. However, new research says running too much could be bad for us. Running long distances {#blank#}1{#/blank#}(regular) for many years could make our life{#blank#}2{#/blank#}(short), not longer. The study is from the Minneapolis Heart Institute. A researcher said too much running can created plague(斑) inside your heart,{#blank#}3{#/blank#}can lead to heart disease. He wrote that running too much for many years takes away the good things from exercise. He{#blank#}4{#/blank#}(add) that the risk of heart disease could be{#blank#}5{#/blank#}same as someone who never exercised.

    Researchers looked{#blank#}6{#/blank#}the health and training of 3,300 runners over the age of 35. 70% of them ran over 30 kilometers a week. Men who ran marathons for 25 years had 62% more plaque in their heart than men who did little{#blank#}7{#/blank#}no exercise. Another doctor said he felt cheated. He started running marathons in 1967. He used{#blank#}8{#/blank#}(run) 60 kilometers every week. He said, “I thought I was out there exhausting{#blank#}9{#/blank#}(me), building an absolutely strong heart.” The doctor advised{#blank#}10{#/blank#}(exercise) frequently but not to overdo things.

    It was a sunny day. A little boy's father was sitting on the couch, drinking a beer, while {#blank#}1{#/blank#} (watch) a basket match. Seeing this, the boy rushed to his father and shouted, “Daddy, Daddy, show me how to play catch!” The father, staring {#blank#}2{#/blank#}  the television screen, replied, “Let me finish watching {#blank#}3{#/blank#} match. Play outside and come back in five minutes.”

    “Okay, Daddy!” said the boy, running out of the room. Five minutes later, the boy returned, screaming , “Daddy, let's go. Let's play catch now !”

    By this time, the father had opened another cold beer and another match was beginning.{#blank#}4{#/blank#} (patient) with the boy's interruption, the dad brought a magazine to his son. On the cover of the magazine was a large picture of the world. The father, who{#blank#}5{#/blank#}(bother) and angry, began tearing the magazine cover into small {#blank#}6{#/blank#} Then, the father turned to his boy and said, “Son, once you put this picture back together, we can play catch,  but do not interrupt me again{#blank#}7{#/blank#} you finish.”

    A few minutes later, the boy returned and said, “I{#blank#}8{#/blank#} (finish), Daddy! Can we play catch now?” Surprised, the father glanced towards his child, and there lay the magazine with the world together. The dad asked his child{#blank#}9{#/blank#} he put the world together so quickly.

    “{#blank#}10{#/blank#} was simple,” said the boy. “On the back of the world was the picture of a person, and once I put the person together, that's when the world came together. ”

    Zac Sunderland is an American who was born in 1991. On July 16^th, 2009 Zac sailed (航行) back to Marina del Rey, California where he had left over a year before. As soon as he arrived, he {#blank#}1{#/blank#} (become) the youngest person in history to sail alone around the world. In order to get the amazing {#blank#}2{#/blank#} (achieve), Zac solved lots of problems.

    When something broke on his boat, {#blank#}3{#/blank#} (thousand) of miles out to sea, Zac had to repair it all by {#blank#}4{#/blank#} (he). Fresh food doesn't last long, so he got used to {#blank#}5{#/blank#} (eat) freeze-dried meals and canned food. And he felt lonely.

    Zac's experiences at sea were not all difficult or miserable(痛苦的). He got {#blank#}6{#/blank#}chances of seeing a night sky more shining than you have ever seen from land, watching {#blank#}7{#/blank#} (beauty) sunrises and sunsets and meeting different marine(海中的) life.

    Zac sailed alone but not non-stop. He made stops along the way {#blank#}8{#/blank#} (add) some more food and fuel. During those stops, he met people from different cultures. His father met him during many of his stops, took him out {#blank#}9{#/blank#} an excellent meal and helped repair the boat {#blank#}10{#/blank#} (frequent).

    The heat wave that broke high temperature records in five European countries a week ago is now over Greenland, {#blank#}1{#/blank#} (cause) the surface of the islands vast ice sheet to melt at near-record levels and a huge {#blank#}2{#/blank#} (lose) of ice in the Arctic. On Wednesday alone, more than 10 billion tons of ice was lost to the oceans by surface melt, which is equal {#blank#}3{#/blank#} about 4,000,000 Olympic-sized swimming pools, said Ruth Mottram, a climate scientist with the Danish Meteorological Institute.

    Melting {#blank#}4{#/blank#} (increase) in recent decades because of climate change and has been decreasing accumulation from snow. Previously, during the 1970s and the 1980s, Greenland lost {#blank#}5{#/blank#} average of 50 billion tons of ice each year. From 2010 to 2018, that figure shot up to 290 billion tons {#blank#}6{#/blank#} (annual). This summer, the extent of the melt could surpass (超过) the record set in 2012, {#blank#}7{#/blank#} about 97% of the ice sheets surface began to melt. NASA-JPL Caltech reported at the time.

Greenland, the worlds largest island, {#blank#}8{#/blank#} (lie) between the Atlantic and Arctic oceans, with 82 per cent of its surface {#blank#}9{#/blank#} (cover) in ice. A June 2019 study by scientists in the U. S. and Denmark said melting ice in Greenland alone will add between 5 and 33 centimeters to the rising {#blank#}10{#/blank#} (globe) sea levels by the year 2100. If all the ice in Greenland melted, which would take centuries, the world's oceans would rise by 7.2 meters.

    Poetry is never far away from our daily lives. Many of us grew up reciting classic poems, learning to enjoy this beautiful art form that's able to use just a few lines {#blank#}1{#/blank#}(express) such rich meanings.

    The Chinese Shijing, which dates back to the Western Zhou Dynasty, has a {#blank#}2{#/blank#}(long) history than the Homeric Epics(荷马史诗). Even today, classic poems {#blank#}3{#/blank#}(love) by a lot of people.

    To recognize the special {#blank#}4{#/blank#}(able) of poetry and get its creative spirit, World Poetry Day is held by the United Nations on March 21 each year to support linguistic diversity through poetic expression.

    The Chinese Poetry Congress(中国诗词大会) showing classic poetry is {#blank#}5{#/blank#}(extreme)popular. The competition saw over 100 hopeful participants taking part in {#blank#}6{#/blank#}number of challenges. The participants, {#blank#}7{#/blank#}ages range from 7 to 70, include students, farmers, teachers and foreign competitors with an interest {#blank#}8{#/blank#}Chinese literature.

    And even TV series involving poetry are very {#blank#}9{#/blank#}(success). For example, in The Legend of Zhenhuan, one of the drama's most moving songs was adapted from a poem {#blank#}10{#/blank#} (write)by Wen Tingyun of the Tang Dynasty.
