10.One theory explaining thesephenomenasuggests that acupuncture blocks pain signals from reaching the brain.

分析 解釋這些現(xiàn)象的一個(gè)理論表明,針灸阻止疼痛信號到達(dá)大腦.

解答 答案是phenomena.考查單詞填空.these后面接名詞復(fù)數(shù)形式.句意是"解釋這些現(xiàn)象的一個(gè)理論表明,針灸阻止疼痛信號到達(dá)大腦."所以用phenomenon的復(fù)數(shù)形式phenomena表示"現(xiàn)象".故答案是phenomena.

點(diǎn)評 本題考查單詞填空.首先要根據(jù)語境明確句意,然后再根據(jù)相關(guān)語法決定正確答案.

18.I really love my job because I enjoy working with small children and like the challenges and awards from the job.I also think my work is important.There was a time when I thought I would never have that sort of career.
I wasn't an excellent student because I didn't do much schoolwork.In my final term I started thinking what I might do and found I didn't have much to offer.I just accepted that I wasn't the type to have a career.
I then found myself a job,looking after two little girls.It wasn't too bad at first.But the problems began when I agreed to live in,so that I would be there if my boss had to go out for business in the evening.We agreed that if I had to work extra hours one week,she'd give me time off the next.But unfortunately,it didn't often work out.I was getting extremely tired and fed up,because I had too many late nights and early mornings with the children.

Now I've got a full-time job there.I shall always be thankful to Megan.I wish I had known earlier that you could have a career,even if you aren't top of the class at school.

15.Years ago,I lived in a building in a large city.The next building was only a few feet away from mine.There was a woman living there,and I had never met her,yet I could see she sat by her window each afternoon,sewing or reading.
After several months had gone by,I began to notice that her window was dirty.Everything was unclear through the dirty window.I would say to myself."I wonder why that woman doesn't wash her window.It really looks terrible."
One bright morning I decided to clean my flat,including washing the window on the inside.
Late in the afternoon when I finished the cleaning,I sat down by the window with a cup of coffee for a rest.What a surprise!Across the way,the woman sitting by her window was clearly visible (看見).Her window was clean!
Then it dawned on me.I had been criticizing (批評) her dirty window,but all the time I was watching hers through my own dirty window.
That was quite an important lesson for me.How often had I looked at and criticized others through the dirty window of my heart,through my own shortcomings?
Since then,whenever I wanted to judge (評判) someone,I asked myself first,"Am I looking at him through my own dirty window?"I try to clean the window of my own world so that I may see the world about me more clearly.
59.The writer couldn't see everything clearly through the window becauseD.
A.the woman's window was dirtyB.the writer was near-sighted
C.the woman lived nearbyD.the writer's window was dirty
60."It dawned on me"probably means"C".
A.I knew it grew light   B.it cheered me up
C.I began to understand itD.it began to get dark
61.It's clear thatC.
A.they both worked as cleaners B.the writer often washed the window
C.the writer had never met the woman beforeD.they lived in a small town
62.From the passage,we can learnA.
A.one must judge himself before he judges others
B.one should often make his windows clean
C.one shouldn't criticize others very often
D.one must look at others through his dirty windows.

By the year 2020,the International Space Station is expected to be retired; while,in the same year,China's space station will be completed.
Zhang Bonan,chief designer of the program,said that the station would be a national,and even international,space lab.
"Experiments there will be different and flexible,"he said,"International cooperation will be encouraged and the door of the station will be open for any experiments that fit the requirements."
●New flight system
A cargo transportation system that supplies goods and propellants (推進(jìn)劑) is key to China building its own space station.
