Two years ago, Jo acted as a teacher in Papua New Guinea. There was no electricity, water or textbooks in the school. When she knew that the students {#blank#}1{#/blank#} (die) to learn chemistry, she tried to show {#blank#}2{#/blank#} (they) chemistry experiments every week. Sometimes, she doubted whether chemistry was relevant{#blank#}3{#/blank#} these students, because most of them would go back to their villages. Actually, they had no{#blank#}4{#/blank#} (person) ambition. The local people had a hard life. Their hut was so dark that it took time for one's eyes {#blank#}5{#/blank#} (adjust). The only possessions {#blank#}6{#/blank#} could be seen were one broom, a few tin plates and cups and a couple of jars. They didn't speak much of the local English dialect. When {#blank#}7{#/blank#} (sit) around, she loved listening to them softly talking to each other in their language{#blank#}8{#/blank#} (occupy) with teaching, she had no time for social{#blank#}9{#/blank#} (activity). Instead, she often joined in their family party. She felt it was {#blank#}10{#/blank#} privilege to spend a day with them.

    I am looking at an old friend of mine.

    He has been one of my best{#blank#}1{#/blank#}(friend )for almost 12 years. He has blessed my life with his loyalty, kindness{#blank#}2{#/blank#}(wise) and love since the day when I first met him{#blank#}3{#/blank#}doesn't matter to me that he has four legs instead of two, fur instead of clothes, and barks at me instead of talking to me.

    As I watch my friend sleeping{#blank#}4{#/blank#}the sun, I cant help{#blank#}5{#/blank#}(think) of all the goodness he has brought into my life. He has been with me every day through good and bad times. He has always been my protector. He has always reminded me that I am loved and showed me how{#blank#}6{#/blank#}(love)others at the same time.

    My friend has aged far{#blank#}7{#/blank#}(quickly)than me and had more and more health problems over the years. I am not sure how long we will be together before he {#blank#}8{#/blank#}(pass)away from this world.

    This {#blank#}9{#/blank#}(wonder)dog has helped me understand that you don't have to be perfect to be loved and{#blank#}10{#/blank#}poor health and old age might affect the body but they don't have to decrease the spirit.

    {#blank#}1{#/blank#}(eat) an egg a day may lower your risk of cardiovascular disease, a study of more than 400,000 adults in China{#blank#}2{#/blank#}(suggestion).

    Daily egg eaters had an 18% lower risk of dying from cardiovascular(心血管的) disease, {#blank#}3{#/blank#}manifests(表现，显现) as heart attacks and strokes,{#blank#}4{#/blank#}(compare) with adults who avoided eggs, according{#blank#}5{#/blank#}the research published Monday in the journal Heart.

    {#blank#}6{#/blank#}(Common) called heart disease, cardiovascular disease includes heart{#blank#}7{#/blank#} (fail), arrhythmias(心律不齐) and heart valve problems in addition to strokes and attacks. Raised blood pressure, carrying too much {#blank#}8{#/blank#}(weigh) or obesity, and elevated(提升) blood sugar all contribute to the risk of cardiovascular disease, which{#blank#}9{#/blank#} trigger (引发)by unhealthy diet, physical inactivity, smoking and{#blank#}10{#/blank#}(harm)use of alcohol.

    There is a tendency to think of each of the arts as {#blank#}1{#/blank#} separate area of activity. Many artists, however, would prove {#blank#}2{#/blank#} there has always been a warm relationship between the a warm relationship areas of human activity. For example, in the late nineteenth century the connections between music and painting were especially close. Artists {#blank#}3{#/blank#} (invite) to design clothes and settings for operas and ballets, {#blank#}4{#/blank#} sometimes it was the musicians who were inspired by the work of contemporary painters. Of the musical compositions as responses to the visual arts, perhaps the most famous is Mussorgsky's Pictures at an Exhibition.

    Mussorgsky composed the piece in 1874 after the death, at the age of 39, of the artist Victor Hartman. {#blank#}5{#/blank#} their friendship had not been a particularly long-lasting one, Mussorgsky was shocked by Hartmann's unexpected death. The following year the critic, Vladimir Stasov, {#blank#}6{#/blank#} decided to told an exhibition of Hartmann's work, suggested that Mussorgsky {#blank#}7{#/blank#} (try) to relieve his grief by writing something in memory of Hartmann.

    The exhibition served as Mussorgsky's inspiration. The ten pieces that make up Pictures at an Exhibition {#blank#}8{#/blank#} (intend) as symbols rather than representation of the paintings in the exhibition. Between each is a promenade (舞曲中 行进), as the composer walks from one painting to {#blank#}9{#/blank#} The music is sometimes witty and playful, sometimes almost alarming and frightening. Thought a range of surprising contrasts, Mussorgsky manages {#blank#}10{#/blank#} (convey) the spirit of the artist and his work.
