As is known to all．medicine comes in different packages． Some in a tablet can make your headache go away． Others from a tube can prevent your cuts from becoming infected． But Call medicine come packaged in chicken eggs?
A team of scientists from Scotland says yes．They have engineered special chickens that can lay eggs with disease—treating drugs inside．These drugs are made of molecules called proteins.Animals make thousands of proteins–they are the main ingredients in skin，hair．milk and meat．Since animals can make proteins easily，they can also make protein drugs．Researchers have already made COWS，sheep and goats produce protein drugs in their milk．But chickens are cheaper to take care of．need less room，and grow faster than other animals．A team of researchers changed chickens’ DNA一the code that tells cells how to make proteins–so that the birds’ cells made two protein drugs．One drug can treat skin cancer，and the other treats a nerve disease。
The scientists changed the chickens’DNA so that the birds made these drugs only in their egg whites．This protects the chickens’bodies from the drugs’possible harmful effects and makes it easy．for scientists to collect the drugs．These special chickens can pass on their drug—laying abilities to their chicks．The scientists need to improve these chickens before they—settle in drug companies′ labs．The birds don′t make enough drugs to treat people yet．But of be day it will come into our daily life．
1.Scientists choose chickens to make protein drugs for the following reason EXCEPT __________。(B)
A. Thiekens grow faster than other animals
B. it‘s easier to change chickens’DNA
C. it costs less to care for chickens
D. Chickens need less room
解析：细节题=根据第二段中的“But chickens are cheaper to take care of，need less room，and grow faster than other animals”可判断A、C、D三项正确．B项未提及，故本题选B。
2.Why do scientists change chickens’DNA?(C)
A. Betcause drugs cannot be collected．
B. Because chickens cannot make proteins．
C. Betcause drugs may bring harmful effects to chickens．
D. Because chickens can only,make drugs in their egg whites．
解析：细节题：根据第二段中的“Animals make thousands of proteins…”可知B项错误：根据第三段中的“The scientists changed the chickens’DN A so that the birds made these drugs only in their egg whites．This protects the chickens’bodies from the drugs’possible harmful effects and makes …”，可知科学家改变鸡的DNA原因有二，一是避免鸡受到药物副作用的影响，二是便于收集药物。A项是对原文的曲解，D项是改变DNA的结果，是实现目的的途径，本题选C。
3.This passage is a piece of__________.(A)
A. exposition
B. description
C. naration
D. argumentation
解析：推断题。本文主要讲述科学家通过改变鸡的DNA使其携带能够治疗疾病的药物文章以阐明事实为主．是一篇典型的说明文exposition“说明文”，对客观事物进行说明和阐释；description“描写文”，捕绘人物、事件、景物等，表现手法以描写、叙述为主；narration“记叙文”，以记人、叙事等为主；argunientation“议论文”，包括论点、论据和论证过程故本题选。
Extraonlinary creative activity has been characterized as revolutionary．flying in the face of what is established and producing not what is acceptable but what will become accepted．According to this formulation．highly creative activity transcends the limits of an existing form and establishes a new, principle of organization．However the idea that extraordinary creativity transcends established limits is misleading when it is applied to the arts， even though it may be valid for the sciences．Differences between highly creative art and highly
