Ⅳ.阅读理解
A
Almost 80% of the Americans have stated their opposition to cloning pet animals such as cats and dogs, yet companies still try to make a business out of selling cloned pets.Pet cloning has been promoted as a way to “bring back” or “copy” a beloved companion animal.However, studies have shown that cloning remains an experimental technology with many failures.
Behind each lovely picture of a cloned cat or dog lie hundreds of animals that were kept in lab cages, receiving bad treatment to produce just that one cloned animal.For all that, you end up with a cloned animal who is unlikely to appear like the original physically or behaviorally and may experience serious health problems.Also, while pet cloning companies are charging customers up to $150,000 for a cloned pet, millions of homeless animals of the same species are available in US animal shelters for around $100.Unfortunately, most of these animals are killed for lack of adopting homes.
With No Pet Cloning campaign, the American Anti-Vivisection Society (AA VS) tries to protect both animals and people from harm.They campaigned until the US companies that sold cloned animals closed their doors.First it was Genetic Savings & Clone Inc.and then it was BioArts International.
When BioArts was closed, its owner, Lou Hawthorne, finally had to acknowledge the problems of pet cloning.According to Hawthorne，he has seen numerous failures during his pet cloning attempts, “One clone—which was supposed to be black and white—was born greenish-yellow where it should have been white (we still have no good explanation for how that happened)．”
The AAVS is educating the public about the animal suffering and is seeking regulation of cloning activities.They will continue to take the lead in protecting animals from the threats of pet cloning.
1．According to the passage, companies keep on selling cloned pets to __B__ .
A．carry on scientific studies B．get economic interests
C．protect pet animals D．comfort animal lovers
解析：细节理解题。

根据第一段companies still try to make a business out of selling cloned pets.一些公司仍然售卖克隆宠物挣钱，获得经济利益。

故选B项。

2．What does the author try to do by writing second paragraph？__A__
A．To tell the truth behind pet cloning.
B．To show the method of pet cloning.
C．To compare pet animals with homeless ones.
D．To save the animals kept in labs and shelters.
解析：推理判断题。

根据第二段第一句可知在克隆猫或狗的美妙图景背后，是为了生产克隆动物，无数的动物被关在实验室的笼子里，接受不良对待这一事实。

故选A项。

3．The underlined word “acknowledge” probably means __C__ .
A．accept B．study
C．admit D．manage
解析：词义猜测题。

根据下句According to Hawthorne, he has seen numerous failures during his pet cloning attempts.据Hawthorne所说，他目睹了宠物克隆实验过程中的无数次失败，可知，他终于承认宠物克隆存在的问题。

故选C项。

B
Scientists in Argentina have created the world’s first cow to own two human genes that will enable it to produce human-like milk, which is matchless up to now.It is a breakthrough in the area of clone.
Genetic engineering was used to introduce the “mothers’mil k” genes into the animal before birth, according to the National Institute of Agribusiness Technology in Buenos Aires.
As an adult, the cloned cow “will produce milk that is similar to that of humans”，which will prove “a development of great importance for the nutrition of infants”，as it is said in a statement.
“The cloned cow, named Rosita ISA, is the first one born in the world that owns two human genes that contain the proteins present in human milk，” the statement said.
In April, scientists in China published details of research showing that they had created GM Holstein dairy cows which produced milk containing proteins found in human breast milk.
But the Argentine team says the Chinese only introduced one human gene, whereas their research involved two genes, meaning the milk will more closely resemble that of humans.
Rosita ISA was born on April 6 and was delivered by Caesarean section because she weighed around 100 pounds, roughly twice the normal weight of Jersey cows.
Adrian Mutto, from the National University of San Martin said, “Our goal was to raise the nutritional value of cows’milk by adding two human genes, the protein lactoferrin and lysozyme，which can provide newly-born babies with anti-bacterial and anti-viral (抗病毒) protection.”
Cristina Kirchner, President of Argentina, said that the scientific institute “makes all Argentines proud”．She also revealed that she had rejected the “honor” of having the cow named after her.“They came to tell me that the name is Cristina, but what woman would like to have a cow named after her? It appeared to me to be more appropriate to call it Rosita.”
语篇解读：文章介绍了阿根廷科学家通过添加人类基因的方式培育出了能生产“类人乳”的牛。

这是基因工程的一项突破。

4. What can we know about Rosita ISA according to the passage？__A__
A．Its milk has larger nutritional value than others’.
B．It is the first cow with a human gene.
C．It is as heavy as Jersey cows.
D．Its milk has the same proteins as human breast milk.
解析：推理判断题。

根据文章第一段第一句．..the world’s first cow to own two human genes...可知，B项中的a human gene错误；根据第七段．..twice the normal weight of Jersey cows.可知C 项错误；根据第六段．..the milk will more closely resemble that of humans.可知，这种奶只是与母乳相似，故D项错误；根据第四段可知，该克隆牛所产牛奶和母乳相似，而且根据倒数第二段可知，它所产的奶在提供婴儿所需的营养方面有重大的进步。

故选A项。

5. Lactoferrin and lysozyme in milk __D__ .
A．can offer more proteins in cow milk
B．help provide more milk from cow
C．can increase the production of milk
D．are good for babies’health
解析：推理判断题。

根据文章倒数第二段中的．..the protein lactoferrin and lysozyme，which can provide newly-born babies with anti-bacterial and anti-viral protection.可知，牛奶中的乳铁蛋白(lactoferrin)和溶菌酶(lysozyme)可以为婴儿提供抗菌和抗病毒的保护，对婴儿的健康有好处。

故选D项。

6. We can infer from the last paragraph that __C__ .
A．it is hard to name the cow
B．the president wants the cow named after her
C．honorable as it is, no women like the cow named after them
D．Cristina Kirchner objects to creating the cloned cow
解析：推理判断题。

根据文章最后一段第三句．..but what woman would like to have a cow named after her？可知，该反问句表示肯定意义，表示没有一个女人愿意一头牛跟自己姓。

故选C项。

7. What would be the best title of the passage？__B__
A．Scientists in Argentina Could Produce Human Milk
B．Scientists Create a Cow That Produces “Human” Milk
C．The Cloned Cow Would Bring About Benefits
D．How Was the Cloned Cow Born?
解析：主旨大意题。

文章第一段第一句提出Scientists in Argentina have created the world’s first cow to own two human genes that will enable it to produce human-like milk，which is matchless up to now.下文围绕该主题进行阐述。

由此可知，本文主题是科学家培育出了一头能生产“类人乳”的牛。

故选B项。

to
find a taxi.We took the boy to a
hospital.The doctors examined the boy quick

his
parents and left after they came to the hospital.
解析：
1．主语是Steven and I，谓语动词应用复数形式。

2．cry for help意为“大声求救”，help是不可数名词，表泛指，前面不用冠词。

3．laying的原形是lay，作“放置”讲；此处应表示“躺”，用lie，其现在分词为lying。

4．fall off是固定短语，意为“从……上摔下来”。

5．前后表示转折，故用转折连词but。

6．few指代可数名词，此处“急救(知识)”是不可数名词，故用little。

7．情态动词后用动词原形。

8．manage to do sth.是固定短语，意为“设法达成某事”，动词不定式作宾语。

9．修饰谓语动词examined应用副词quickly。

10．代词的指代应与上文中的the boy一致，故用his。
