All scientists subscribe {#blank#}1{#/blank#} the view that it is human activities that have caused the global warming. Huge {#blank#}2{#/blank#} (quantity) of carbon dioxide produced by burning fuels like coal,  natural gas and oil {#blank#}3{#/blank#} (result) in the "greenhouse effect". All scientists also agree that the levels of carbon dioxide keep on {#blank#}4{#/blank#} (increase), so more heat energy tends to be {#blank#}5{#/blank#} (trap) in the atmosphere. {#blank#}6{#/blank#} the scientists have different attitudes towards this phenomenon. On the one hand, some think the {#blank#}7{#/blank#} of increasing the temperature by 5 degrees would be a catastrophe. On the other hand, others are {#blank#}8{#/blank#} to this view and believe that there will be few bad environmental {#blank#}9{#/blank#} caused by more carbon dioxide. On the contrary, they think it will be beneficial to plants, crops and a greater range of animals, {#blank#}10{#/blank#} will make people's life better.

    The party began shortly after nine. Mr. Wood, who lived in the flat below, sighed to himself as he heard {#blank#}1{#/blank#} （excite） voices and the noisy music. Luckily, he had brought some work home from the office, with {#blank#}2{#/blank#} he kept himself busy for a couple of hours, thus managing to pay no attention{#blank#}3{#/blank#}the noise overhead. But by eleven o'clock he felt tired and was ready to go to bed though from his {#blank#}4{#/blank#}（early） experience he knew it was no use{#blank#}5{#/blank#}（try） to get to sleep. He undressed and{#blank#}6{#/blank#}（lie） for a while in bed, trying to read, but he found himself reading the same page over and over again. He then turned off {#blank#}7{#/blank#} light and buried his head in the pillow. But even so he could not shut off the noise. Finally, after{#blank#}8{#/blank#} seemed hours, his patience was gone.

    He jumped out of bed, put on some clothing, marched firmly up the stairs, and walked into his neighbor's apartment. The owner of the apartment came across the room and, {#blank#}9{#/blank#}Mr. Wood could say anything, cried, "My dear fellow, come and join us. I know our parties would trouble you. I meant to send you an invitation." Mr. Wood's anger disappeared then and there. He said, "I'd better go and get changed." Minutes later, he returned,{#blank#}10{#/blank#}（proper） dressed, only to find that the party was nearly over.

    In our daily life, we often meet with difficulties. Some people do nothing but wait, while others try hard to conquer{#blank#}1{#/blank#}. Personally, we should face with difficulties positively and make every effort to overcome them.

    My memory drew me back to five years ago when I was {#blank#}2{#/blank#} middle school student. At that time, I had great trouble studying English. First of all, I felt it hard to memorize English {#blank#}3{#/blank#}(word). Besides I didn't dare to say anything in class when {#blank#}4{#/blank#} (ask) questions. What annoyed me most was that I failed exams {#blank#}5{#/blank#}(constant). I was about to give up {#blank#}6{#/blank#} my English teacher found my problems. He encouraged me and gave me some good advice. So {#blank#}7{#/blank#} (inspire) by him, I decided to settle my problems.{#blank#}8{#/blank#}(follow) his advice, I made progress gradually. I owe my achievement {#blank#}9{#/blank#} the teacher whose encouragement was of great {#blank#}10{#/blank#}.(important).

    Smell the flowers before you go to sleep and you may just end up with rosy dreams. Have a whiff of rotten(腐烂的)eggs during the night and your dreams may be {#blank#}1{#/blank#}(pleasant). So says researcher Dr. Boris Stuck, {#blank#}2{#/blank#}invited sleeping volunteers to a rose vs. rotten egg test in the University Hospital Mannheim in Germany. The subjects didn't dream about roses {#blank#}3{#/blank#}eggs, but rather he found that what they smelt affected the emotions of {#blank#}4{#/blank#}(they) dreams.

    And if you think {#blank#}5{#/blank#}(smell) have a say in dreams, wait for what TV tells us. A UK study reveals that people exposed {#blank#}6{#/blank#}black-and-white film and TV in their youth are to have monochromic(单色的)dreams throughout their life more {#blank#}7{#/blank#}(probable). Eva Murzyn from the University of Dundee tested two age groups— one half {#blank#}8{#/blank#}(age) over 55 and {#blank#}9{#/blank#}other half under 25.

    The result? Under 5% of the dreams of the under-25s were in black and white. {#blank#}10{#/blank#}(watch)color TV in childhood seems to be the reason why.
