小題1:Painkillers in a tablet can make your headache go away. Antibiotic cream(抗生膏)from a tube can prevent your cuts from becoming infected. But can medicine come packaged in chicken eggs?
A team of scientists from Scotland says yes. They've engineered special chickens that lay eggs with disease -treating drugs inside.
小題2:Animals make thousands of proteins—they’re the main ingredient in skin, hair, milk, and meat. Since animals can make proteins easily, they’re good candidates for making protein drugs.
Researchers have already made cows, sheep, and goats that pump out protein drugs in their milk. But chickens are not expensive to take care of; what’s more, they need less room, and grow faster than these other animals. “小題3:”says Simon Lillico of the Roslin Institute near Edinburgh, Scotland.
Lillico and a team of researchers changed chickens’ DNA—the code that tells cells how to make proteins so that the birds’ cells made two protein drugs. 小題4:
The scientists altered the chickens’ DNA so that the birds made these drugs only in their egg whites (蛋清). 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. 小題5:The scientists need to improve these chickens before they roost (棲息) in drug companies’ labs. The birds don’t make enough drugs to treat people yet. But once the researchers perfect their technique, you might eventually take your medicine sunny-side up.
A.Medicine comes in lots of different uses.
B.Those qualities could make chickens a better choice to become living drug factories.
C.So far, the Scottish researchers have bred five generations of drug—producing birds.
D.Some chickens are found having the ability of treating diseases.
E. One drug can treat skin cancer, and the other treats a nerve disease called multiple sclerosis(硬化).
F. These drugs are made of molecules called proteins.
G. Medicine comes in lots of different packages.

試題分析:這是一篇科技類(lèi)閱讀。一組來(lái)自蘇格蘭的科學(xué)家說(shuō)可以。他們研制出一種特殊的雞。這種雞生的蛋里面含有治病藥品。這些藥品都來(lái)自于那些經(jīng)設(shè)計(jì)后能在其蛋白中產(chǎn)出某些藥品的雞。這些藥品都是由叫做蛋白質(zhì)的分子構(gòu)成的。
小題1:根據(jù)后文Painkillers in a tablet can make your headache go away. Antibiotic cream from a tube can prevent your cuts from becoming infected. But can medicine come packaged in chicken eggs? 片劑類(lèi)止痛藥能消除你的頭痛。裝在管子中抗生素膏能預(yù)防你傷口感染。但藥品能裝在雞蛋中嗎?可知這里應(yīng)該是:藥品有不同的包裝。故選G。
小題2:根據(jù)后句Animals make thousands of proteins動(dòng)物能產(chǎn)生很多的蛋白質(zhì)?芍@里應(yīng)該是These drugs are made of molecules called proteins.這些藥是由叫蛋白質(zhì)的成分構(gòu)成。故選F。
小題3:根據(jù)前文But chickens are not expensive to take care of; what’s more, they need less room, and grow faster than these other animals.但是雞飼養(yǎng)成本更低,而且所需空間較小,生長(zhǎng)較其它動(dòng)物快。所以這里應(yīng)該是:Those qualities could make chickens a better choice to become living drug factories雞的這些特性使之成為轉(zhuǎn)化成活性藥品工廠的最佳選擇。故選B。
小題4:根據(jù)前文the birds’ cells made two protein drugs這樣雞的細(xì)胞就能產(chǎn)生兩種蛋白質(zhì)藥品。可知接著要說(shuō)明這兩種蛋白質(zhì),故用One drug can treat skin cancer, and the other treats a nerve disease called multiple sclerosis一種治療癌癥,另一種治療叫做多樣硬化的神經(jīng)方面的疾病。故選E。
小題5:根據(jù)后文The scientists need to improve these chickens before they roost (棲息) in drug companies’ labs在這些雞進(jìn)入藥廠的實(shí)驗(yàn)室之前,科學(xué)家還得對(duì)這些雞進(jìn)行改善?芍@里應(yīng)該是:So far, the Scottish researchers have bred five generations of drug—producing birds.到現(xiàn)在為止,蘇格蘭科學(xué)家已經(jīng)五種生產(chǎn)藥品的鳥(niǎo)。故選C。
