9.Imagine what you could do with a machine that could make things disappear.
(36)F In the books of J.R.R.Tolkein,Bilbo Baggins finds a ring that can make him disappear.Of course,there's also poor Harry Potter,who used his invisibility cloak (隱形斗篷)to hide  from danger.
Now that you've got some ideas,it's time for the hard part:building the cloak.(37)G
An invisibility cloak has to cheat anything or anyone who might be watching.In order to understand how something can be seen,it's important to understand how we see.
Human beings can only see objects that reflect light waves.These waves enter the eyes and are then processed by the brain.However,if an object doesn't reflect light,then the waves don't enter the eyes,and the brain doesn't process.(38)C
Cummer was part of a team of scientists from Duke University,including David Smith and David Schurig,who built the world's first version of an invisibility cloak.(39)EHe in May said that an invisibility cloak was possible and Pendry was not the only one thinking about a disappearing act.At the same time,a Scottish physicist,Ulf Leonhardt published a paper on building invisibility equipment.
"It wasn't easy,"says Cummer."As often happens in science and research,it didn't work very well the first time.That first cloak didn't work like Harry Potter's-(40)BSo the research is still under way."

A.Would you like an invisibility cloak that works just like the one Harry Potter got from his father?
B.The scientists didn't actually seeanything disappear.
C.So building an invisibility cloak is building something that doesn't reflect light.
D.Researchers in England and the USA have found the materials to build such a cloak.
E.They had been inspired by the work of a British physicist,John Pendry.
F.For inspiration,you could read some books.
G.To do that,you have to give up science fiction and turn to real science.

分析 本文屬于說明文閱讀,作者通過這篇文章主要向我們描述了一個(gè)關(guān)于制造隱形斗篷的研究,然而制作隱形斗篷并不容易,盡管已經(jīng)出現(xiàn)了隱形斗篷的第一個(gè)版本,但并不能像哈利波特的斗篷一樣使物體消失,研究還在不斷嘗試中.

解答 36.F.推理判斷題.根據(jù)文章第二段"In the books of J.R.R.Tolkein,Bilbo Baggins finds a ring that can make him disappear"在J.R.R.Tolkein的書,Bilbo Baggins 發(fā)現(xiàn)了一個(gè)可以讓他消失的戒指,可推測前文應(yīng)為為了獲得靈感,你可以讀一些書;故選F.
37.G.推理判斷題.根據(jù)文章第三段"An invisibility cloak has to cheat anything or anyone who might be watching.In order to understand how something can be seen,it's important to understand how we see"一件隱形斗篷必須欺騙任何會(huì)被看到的人活事物,為了了解什么是可以被看到的,這是非常重要的去了解我們?nèi)绾慰吹绞挛锏模豢赏茰y前文應(yīng)為要制作隱形斗篷,你必須放棄科幻小說,轉(zhuǎn)向真正的科學(xué);故選G.
38.C.推理判斷題.根據(jù)文章第四段"However,if an object doesn't reflect light,then the waves don't enter the eyes,and the brain doesn't process"可知如果一個(gè)物體不反射光,那么波不進(jìn)入眼睛,大腦不處理,人們便看不見;因此前文為所以建立一個(gè)隱形斗篷是建立一個(gè)不反射光的東西;故選C.
39.E.推理判斷題.根據(jù)文章第五段:Cummer was part of a team of scientists from Duke University,including David Smith and David Schurig,who built the world's first version of an invisibility cloak,Cummer是一隊(duì)來自杜克大學(xué)的科學(xué)家,包括David Smith和David Schurig,他們建造了世界上的隱形斗篷的第一個(gè)版本,可推測后文為他們?cè)挥锢韺W(xué)家John Pendry的工作鼓舞;故選E.
40.B.推理判斷題.根據(jù)文章最后一段"As often happens in science and research,it didn't work very well the first time.That first cloak didn't work like Harry Potter's"正如科學(xué)研究中經(jīng)常發(fā)生的那樣,第一次總是不能做的很好,這第一件斗篷并沒有像哈利•波特那樣;可知后文為科學(xué)家們實(shí)際上并沒有看到什么東西消失;故選B.

點(diǎn)評(píng) 七選五閱讀是完成性閱讀,和完形填空很類似,不同的是一個(gè)選詞,一個(gè)選句子.解題時(shí),要注意上下文語境,充分考慮信息詞(選項(xiàng)中和空格前后句子中相同或相近的詞),選出最符合語境的句子.

17.Life is difficult.
    It is great truth because once we truly understand and accept it,then life is no longer difficult.
 Most do not fully see this truth.Instead,they complain about their problems and difficulties as if life should be easy.It seems to them that difficulties represent a special kind of suffering especially forced upon them or upon their familie s,their class,or even their nation.
 What makes life difficult is that the process of facing and solving problems is a painful one.Problems,depending on their nature,cause us sadness,loneliness or regret or anger and fear.These are uncomfortable feelings,often as painful as any kind of physical pain.And since life causes an endless series of problems,life is always difficult and is full of pain as well as joy.
Yet,it is in this whole process of solving problems that life has its meaning.Problems are the serious tests that tell us success from failure. When we desire to encourage the growth of human spirit,we encourage the human ability to solve problems,just as in school we set problems for our children to solve.It is through the pain of meeting and working out problems that we learn.As Benjamin Franklin said,"Those things that hurt instruct."It is for this reason that wise people learn not to fear but to welcome the pain of problems.
25.From the passage,it can be inferred thatB.
A.everybody has problems
B.we become stronger by meeting and solving the problems of life
C.life is difficult because our problems bring us pain
D.people like to complain about their problems
26. The writer probably used just one short sentence in the first paragraph toD.
A.save space

B.the writer feels life is easy
C.the writer likes to complain about his problems
