5.As part of an effort to improve treatments for life-threatening illnesses,a team of scientists have created rabbits that glow in the dark.
Their efforts have produced two rabbits out of a litter of eight that went from being a normal,soft white to glowing green in the dark.The rabbits were born at the University of Istanbul as part of the collaboration between scientists from universities in Turkey and Hawaii.
The rabbits glow to show that a genetic operation 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(水母)DNA into a mother rabbit's embryos.Then those embryos were inserted back into the mother.Similar experiments have resulted in glowing cockroaches(蟑螂)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 are able to produce beneficial molecules(分子)in their milk that can be cheaply extracted(提取),especially in countries that cannot afford big factories that make drugs,which  usually cost US $1 bn to build.Then they will 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,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.
31.What do we know about the glowing rabbits?D
A.They live shorter lives than ordinary rabbits.
B.Their fur became green after the experiment.
C.They were chosen from a special species of rabbits.
D.The color that they glow isn't of interest to scientist.
32.Why did scientists conduct the experiment to create glowing rabbits?C
A.To research  animal genes.
B.To improve animal species.
C.To produce cheap,beneficial medicine.
D.To improve animal's ability to resist disease.
33.Which animal wasn't used as the test subject?C
A.The cat.B.The jellyfish.C.The sheep.D.The cockroach.
34.Which of the following is TRUE,according to the passage?C
A.The project is supported by people.
B.The success rate in creating the rabbits is 20%.
C.The project has been conducted for more than nine years.
D.The project is mainly conducted by Turkish scientists.
35.What is Moisyadi's attitude towards such experimentation?B
A.Doubtful.B.Supportive.C.Disapproving.D.Indifferent.

分析 一只发光的兔子听起来就像来自迷幻歌曲中的一种生物,但是夏威夷大学马诺阿分校的遗传学家Ryuzo Yanagimachi和Stefan Moisyadi与土耳其伊斯坦布尔大学的研究人员合作,成功培育出了一只真正的荧光兔子.科学家们想利用这个技术来研究药物.

解答 31.D,推理判断题,根据Stefan Moisyadi说的话The green is not important at all-it's just a marker to show the experiment can be done successfully可知,科学家对兔子发出的绿色不感兴趣,故答案为D.
32.C,推理判断题,根据句子The final goal is to develop animals that are able to produce beneficial molecules(分子)in their milk that can be cheaply extracted(提取),especially in countries that cannot afford big factories that make drugs,which usually cost US $1 bn to build.Then they will be able to produce their own protein-based medication in animals可知,科学家做这个实验是为了提取出有效的便宜的药物,故答案为C.
33.C,细节理解题,根据句子To produce the glowing effect,researchers injected jellyfish(水母)DNA into a mother rabbit's embryos.Then those embryos were inserted back into the mother.Similar experiments have resulted in glowing cockroaches(蟑螂)and cats.可知,绵羊没有作为研究对象,故答案为C.
34.C,细节理解题,根据句子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可知,这个项目已经实施超过九年了,故答案为C.
35.B,推理判断题,根据句子And if the benefits outweigh the injuries,let's go with the benefits可知,Moisyadi认为如果好处大于坏处,就往好的方面看,可见他是支持的,故答案为B.

8.The ninth week of SEAL(Sea,Air,Land) training is referred to as Hell Week.It is six days of no sleep,physical and mental suffering and one special day at the Mud Flats (泥沼)where you will sink into the mud.
It is on Wednesday of Hell Week that we came down to the mud flats and spend the next 15 hours keeping alive in the freezing-cold mud,the cold wind and the strong pressure from the instructors to give up.
As the sun began to set that Wednesday evening,my training class,having broken some of the rules,was ordered into the mud.We sank into the mud until only our heads could be seen.The instructors told us we could leave the mud if only five men would give up---just five men and we could get out of the cold.
Looking around the mud flat,it was clear that some of us were about to give up.It was still over eight hours till the sun came up---eight more hours of coldness.Our cries were so loud that it was hard to hear anything.And then,one voice began to fly through the night---one voice raised in song.
The song sounded terrible,but it was sung with great power.One voice became two,and two became three,and before long everyone in the class was singing.
We knew that if one man could rise above the suffering then others could as well.The instructors warned us of more time in the mud if we kept up the singing---but the singing went on and on.And somehow,the mud seemed a little warmer,the wind a little weaker and the morning not so far away.
If I have learned anything in my time traveling the world,it is the power of hope.The power can change the world by giving people hope.
So,if you want to change the world,start singing when you're up to your neck in mud.

15.Cookies don't really matterAs I sat beside the window of our classroom that afternoon,my heart sank further with each passing car.This was a day I'd looked forward to for weeks:Miss Pace's fourth-grade,end-of-the-year party.
I had happily volunteered (主动推荐) my mother when Miss Pace looked for cookie (小甜饼) volunteers.Mom's chocolate chips were well-known,and I knew they'd be popular with my classmates.But two o'clock passed,and there was no sign of her.Most of the other mothers had already come and gone,dropping off their sweet offerings (礼物).
The three o'clock bell soon took me away from my thoughts ad I took my book bag from my desk.
I decided I would slam (摔) the front door,and refuse to return her hug.But when I arrived,she wasn't at home.I was lying face-down on my bed upstairs when I heard her come through the front door."Robbie,"she called out a bit urgently (急切地)."Where are you?"I could then hear her rushing anxiously from room to room,wondering where I could be.I remained silent.
Coming through the door,she said:"I'm so sorry,honey,"she said."I just forgot.I got busy and forgot."Then my mother did something completely unexpected.Sh began to laugh!How could she laugh at a time like this?I rolled over and faced her,ready to let her see my anger.But my mother wasn't laughing at all.She was crying."I let you down.I let my little boy down."I was moved by her tears.I tried to remember her kind words from times past when I'd skinned knees or cut myself,times when she knew just the right thing to say."It's okay,Mom.We didn't even need those cookies.There was plenty of stuff to eat.Don't cry.It's all right.Really."
We didn't say another word.We just held each other.When we came to the point where I would usually pull away (离开),I decided that,this time,I could hold on,perhaps,just a little bit longer.
