Question

19．The technique can lead to new ways to produce medicines，the researchers from the universities of Istanbul and Hawaii hope．
As part of an effort to improve treatments for life-threatening illnesses，a team of scientists have created rabbits that glow（發(fā)光） in the dark．
Their efforts produced two rabbits out of a litter of eight that went from being a normal，fluffy white to glowing green in the dark．The rabbits were born at the University of Istanbul as part of a collaboration（合作） between scientists from universities in Turkey and Hawaii．
The rabbits glow to show that a genetic manipulation technique can work efficiently，though the specific color is more cosmetic than scientific．"The green is not important at all-it's just a marker to show the experiment can be done successfully，"said University of Hawaii associate professor Stefan Moisyadi．
To produce the glowing effect，researchers injected jellyfish DNA into a mother rabbit's embryos．Those altered embryos（胚胎）．Those altered embryos were then inserted back into the mother．Similar experiments have resulted in glowing cockroaches and cats．
Eventually，the researchers hope the technique can lead to new ways to produce medicines，Moisyadi said．"The final goal is to develop animals that act as barrier reactive to produce beneficial molecules in their milk that
can be cheaply extracted，especially in countries that can't afford big pharma plants that make drugs，that usually cost $1bn to build，and be able to produce their own protein-based medication in animals，"Moisyadi said．
The rabbits are expected to have the same life span as their non-glowing counterparts（副本），but Moisyadi said he understands people can object to this kind of experimentation involving live animals．
"To the people against，I say：think about，what are the benefits and what are the injuries？"Moisyadi said．"And if the benefits outweigh the injuries，let's go with the benefits．"
Moisyadi，a native of Turkey who is now with the University of Hawaii，started developing the project in 2006，and researchers are now waiting to see if pregnant sheep produce similar results．

21．Moisyadi's attitude towards this kind of experiment isC．
A．doubtful．
B．indifferent．
C．supportive．
D．objective．
22．How did glowing effect produce？D
A．It was just the result of genetic selection．
B．Put a light into a mother rabbit's embryos．
C．Injected glowing cats DNA into a mother rabbit's embryos．
D．Injected Jellyfish DNA into a mother rabbit's embryos．
23．The final goal of this research isD．
A．To make animals cuter．
B．To make nights brighter．
C．To produce all kinds of glowing animals．
D．To produce beneficial molecules in animals'milk．
24．What can we learn according to the passage？C
A．The life span of glowing rabbits is much shorter than that of non-glowing ones．
B．The glowing rabbits were born only at the University pf Hawaii．
C．Scientists have created glowing cockroaches and cats before．
D．Three rabbits out of eight can glow in the experiment．

Answer 1

分析 經(jīng)過研究人員的努力，土耳其和夏威夷大學(xué)的科學(xué)家們合作培育出能發(fā)光的兩只兔子，研究人員希望該技術(shù)最終能產(chǎn)生生產(chǎn)藥物的新方法．

解答 21．C推理判斷題，倒數(shù)第二段""To the people against，I say：think about，what are the benefits and what are the injuries？"Moisyadi said．"And if the benefits outweigh the injuries，let's go with the benefits．"和最后一段的"Moisyadi，… started developing the project in 2006，"可知他是支持的．故選C．
22．D　細(xì)節(jié)理解題．根據(jù)第五段"To produce the glowing effect，researchers injected jellyfish DNA into a mother rabbit's embryos．Those altered embryos（胚胎）．Those altered embryos were then inserted back into the mother．"為了使之產(chǎn)生發(fā)光效果，研究人員在母兔的胚胎中注入水母的DNA，再把這些變異的胚胎植回母體．可知選D．
23．D　細(xì)節(jié)理解題，根據(jù)"The final goal is to develop animals that act as barrier reactive to produce beneficial molecules in their milk…"最終目標(biāo)是培育乳汁中含有有益分子．故選D．
24．C 推理題．根據(jù)文章內(nèi)容，To produce the glowing effect，researchers injected jellyfish DNA into a mother rabbit's embryos．Those altered embryos（胚胎）．Those altered embryos were then inserted back into the mother．Similar experiments have resulted in glowing cockroaches and cats．相似的實(shí)驗(yàn)曾使用在發(fā)光的蟑螂和貓身上，即曾經(jīng)創(chuàng)造出過這樣的發(fā)光的蟑螂和貓，結(jié)合選項(xiàng)，故選C

點(diǎn)評(píng) 題目涉及多道細(xì)節(jié)理解題，做題時(shí)結(jié)合原文和題目有針對性的找出相關(guān)語句進(jìn)行仔細(xì)分析，結(jié)合選項(xiàng)選出正確答案．推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案，切忌胡亂猜測，一定要做到有理有據(jù)．
