第三部分 閱讀理解 (共20小題；每小題2分，滿分40分)
閱讀下列短文，從每題所給的四個(gè)選項(xiàng)(A、B、C和D)中，選出最佳選項(xiàng)。
A
The
The Food and Drug Administration says meat and milk from clones of adult cattle, pigs and goats are safe to eat. An FDA official called them “as safe to eat as the food we eat every day.” And when those clones reproduce sexually, the agency says, their offspring(后代)are safe to eat as well. But research on cloned sheep is limited. So the FDA proposes that sheep clones not be used for human food.
The
The agency says it must receive comments by April second. The FDA seemed ready to act several years ago, but a committee called for more research.
For now, the government will continue to ask producers to honor a request that they not sell foods from cloned animals.
Clones are still rare. They cost a lot and are difficult to produce.
The FDA says most food from cloning is expected to come not from clones themselves, but from their sexually reproduced offspring. It says clones are expected to be used mostly as breeding animals to spread good qualities.
Public opinion studies show most Americans do not like the idea of food from cloned animals. But this research also shows the public knows little about cloning.
Cloning differs from genetic engineering. A cell taken from a so-called donor animal is grown into an embryo(胚胎) in the laboratory. Next, the embryo is placed into the uterus(子宮) of a female animal. If the process is successful, the pregnancy reaches full term and a genetic copy of the donor animal is born.

A. To tell an interesting story. B. To give some advice on foods.
C. To give a report. D. To compare different opinions.
57. Who believe that foods from cloning are safe to eat?__________
A. Most Americans B. An advisory committee C. Critics D. The FDA
58. It can be inferred from the last paragraph that_____.
A. cloning has much in common with genetic
B. not every cell taken from a donor animal can grow into a genetic copy

D. cloned animals grow faster than normal ones
59. Which of the following is true about foods from cloning?_______________
A. They come from the sexually reproduced offspring of cloned animals.
B. The food from first-generation cloned animals is very expensive.
C. Only FDA has the right to sell the food.

答案與解析
1-5:CBABC 6-10:CBABC 11-15:ABCAC 16-20:ABCAB

22.D考查句式結(jié)構(gòu)和語序。注意本句不是強(qiáng)調(diào)句，而是it做主語表示時(shí)間，before引導(dǎo)時(shí)間狀語從句的it be+一段時(shí)間+before引導(dǎo)的狀語從句，表示“在……之前有多久，多長(zhǎng)時(shí)間之后……”。句意：你知道奧巴馬還要等多長(zhǎng)時(shí)間才正式在白宮上任嗎？

25.C考查形容詞句式。這里用“the+比較級(jí)，the+比較級(jí)”結(jié)構(gòu)表示“越……就越”。從語境和選項(xiàng)看，A項(xiàng)的語序和時(shí)態(tài)不對(duì)，B項(xiàng)的形容詞不對(duì)，D項(xiàng)差冠詞，只有C項(xiàng)正確。
26.C考查虛擬語氣。語境表示與過去實(shí)際情況相反的假設(shè)，用過去完成時(shí)，表示“我真希望當(dāng)初注意自己的發(fā)音問題了”。
27.B考查倒裝句。從語境看，本題用否定意義的副詞little放在句首，句子用倒裝句。

B．疫苗進(jìn)入機(jī)體與抗原結(jié)合，使抗原失去增殖能力，并形成沉淀等，由吞噬細(xì)胞予以清除C．以該病毒核衣殼蛋白為抗原制備的單克隆抗體不一定能診斷出流感病毒感染者
D．流感疫苗研究比天花疫苗研究困難，原因在于它們遺傳物質(zhì)的差別
4．下列與生態(tài)系統(tǒng)的有關(guān)敘述，正確的是（ ）
A．各類生態(tài)系統(tǒng)均由生產(chǎn)者、消費(fèi)者和分解者組成
B．生物圈是一個(gè)自給自足的生態(tài)系統(tǒng)
C．碳在生物群落與無機(jī)環(huán)境之間的循環(huán)主要以CO2的形式進(jìn)行
D．通過光合作用同化太陽能總量為A的草場(chǎng)上，生活著一定數(shù)量的牛和羊，這些牛和羊均可最多獲得A/5的能量
5．下圖用不同形式表示了雜交瘤細(xì)胞產(chǎn)生抗體過程中，細(xì)胞中有關(guān)膜面積的變化，下列分析正確的是（ ）
