Question

根據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。
  __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.
  _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. “  __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.  __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.  __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.

Answer 1

小題1:G
小題2:F
小題3:B
小題4:E
小題5:C

試題分析：
小題1:根據(jù)后面的句子：But can medicine come packaged in chicken eggs?
可知藥的包裝各種各樣：答案是：G
小題2:根據(jù)后面的句子：Animals make thousands of proteins—they’re the main ingredient in skin, hair, milk, and meat.可知這些藥是蛋白質(zhì)分子組成的，答案是：F
小題3:根據(jù)前面的句子：可知藥的這些特點使它成為藥廠的很好的選擇，答案是：B
小題4:根據(jù)前面的句子：the code that tells cells how to make proteins so that the birds’ cells made two protein drugs可知下面介紹這兩種藥物，答案是：E
小題5:根據(jù)前面的句子：These special chickens can pass on their drug-laying abilities to their chicks.可知科學(xué)家已經(jīng)繁殖了五代可以做藥的雞了。答案是：C
點評：在答題中，應(yīng)首先略讀一下短文，了解一下短文的大致意思，然后把幾個選項含義理解透，尤其注意意思相近，表達有交叉的選項之間的區(qū)別。然后再細讀短文，把答案填入合適位置。答題時可以把含義相近的幾個選項輪流填入同一處位置，反復(fù)閱讀，反復(fù)體會，找出最佳選項，對于實在沒有把握的小題可以留待最后完成。完成短文后，再認真通讀一遍全文，看看上下語意是否通順，是否符合邏輯關(guān)系。
