    Chinese scientists recently have produced two monkeys with the same gene, Zhong Zhong and Hua Hua, using the same technique that gave us Dolly the sheep. These monkeys are not actually the first primates(灵长类)to be cloned. Another one named Tetra was produced in the late 1990s by embryo(胚胎)splitting, the division of an early-stage embryo into two or four separate cells to make clones. By contrast, they were each made by replacing an egg cell nucleus(原子核)with DNA from a differentiated body cell. This Dolly method, known as somatic cell nuclear transferSCNT, can create more clones and allows researchers greater control over the edits they make to the DNA.

Success came from adopting several new techniques. These included a new type of microscopy to better view the cells during handling or using several materials that encourage cell reprogramming, which hadn’t been tried before on primates. Still, the research process proved difficult, and many attempts by the team failed. Just two healthy baby monkeys born from more than 60 tested mothers. This leads to many researchers’ pouring water on the idea that the team’s results bring scientists closer to cloning humans. They thought this work is not a stepping stone to establishing methods for obtaining live born human clones. Instead, this clearly remains a very foolish thing to attempt, it would be far too inefficient, far too unsafe, and it is also pointless.

But the scientists involved emphasize that this is not their goal. There is now no barrier for cloning primate species, thus cloning humans is closer to reality. However, their research purpose is entirely for producing non-human primate models for human diseases; they absolutely have no intention, and society will not permit this work to be extended to humans. Despite limitations, they treat this breakthrough a novel model system for scientists studying human biology and disease.

1.What do we know about the technology called SCNT?

A. It created the first two primates.

B. It may contribute to editing the DNA.

C. It can divide an early-stage embryo into several cells.

D. It produced two cloned monkeys with different genes.

2.What does the author mean by “pouring water on the idea” in paragraph 2?

A. Keeping a hot topic of it.

B. Attaching no importance to it.

C. Having a low opinion of it.

D. Adding supportive evidence to it.

3.What is the scientists’ purpose to clone these monkeys?

A. To prepare for their research on human cloning.

B. To serve as a stepping stone to their reputation.

C. To help with the study of human diseases.

D. To raise money for holding an exhibition of novels.

4.What can we infer from the passage?

A. Cloning humans is already on its way.

B. New techniques seem to be pointless.

C. Society won’t agree to clone another monkey.

D. The success rate of cloning a monkey was not high.

 

1.B 2.C 3.C 4.D 【解析】 本文是一篇科普类的文章。被称作SCNT的高科技可能有助于编辑DNA。本文中科学家们克隆这些猴子的目的是帮助研究人类疾病。 1.细节理解题。根据第一段最后一句This Dolly method, known as somatic cell nuclear transfer(SCNT), can create more clones and allows researchers greater control over the edits they make to the DNA.可知,SCNT可能有助于编辑DNA。故B项正确。 2.词义猜测题。根据第二段中Still, the research process proved difficult, and many attempts by the team failed. Just two healthy baby monkeys born from more than 60 tested mothers. This leads to many researchers’ pouring water on the idea that the team’s results bring scientists closer to cloning humans.可知在第二段中“pouring water on the idea”的意思是“对它的评价很低。”故C项正确。 3.推理判断题。根据最后一段中However, their research purpose is entirely for producing non-human primate models for human diseases; they ly have no intention, and society will not permit this work to be extended to humans.可知,科学家们克隆这些猴子的目的是帮助研究人类疾病。故C项正确。 4.推理判断题。根据倒数第二段最后两句They thought this work is not a stepping stone to establishing methods for obtaining live born human clones. Instead, this clearly remains a very foolish thing to attempt, it would be far too inefficient, far too unsafe, and it is also pointless.和最后一段最后一句Despite limitations, they treat this breakthrough a novel model system for scientists studying human biology and disease.可知,克隆一只猴子的成功率并不高。故D项正确。

People usually visit cafes to ease themselves of their tiredness and keep themselves from falling asleep, but Mr. Healing, a popular cafe chain in South Korea actually does the opposite. Customers can come in, order a drink, lie down in a comfortable massage chair, and take a nap.

Many Koreans suffer from a lack of sleep as a result of overworking, so any opportunity to relax and even take a nap is greatly appreciated. Mr. Healing is the perfect place to go when you’re on a short work or school break and you need to catch up on sleep. The cafe offers massage periods in various modes, depending on how much time you have and how you choose to spend it.

The 20-minute session is priced at $3.5, the 30-minute massage costs $7, and the 50-minute session is $9, all of which also include a drink. Once you make your choice, you are taken to the “healing center”. You are asked to take off your shoes as well as any jewelry that might damage the chairs, after which you can choose a massage mode, from “stretch” or “sleep”. You can start with stretch for a few minutes, and then switch to sleep if you want to take a short nap. After it comes to an end, you are taken back to the cafe area to enjoy a coffee or one of the many other refreshing drinks on the menu.

Mr. Healing cafes are so popular in Korea that customers are advised to make reservations in advance to be sure that a massage chair is available. “I have to sit on a chair and stare at a computer monitor all day due to my job, the healing room was truly effective to relieve tiredness and stress from weekdays,” said Park Hye-sun, a 24-year-old officer.

Sandra Cisneros was born in Chicago in 1954 to a Mexican American family. As the only girl in a family of seven children, she often felt like she had “seven fathers,” because her six brothers, as well as her father, tried to control her. Feeling shy and unimportant, she retreated(躲避)into books. Despite her love of reading, she did not do well in elementary school because she was too shy to participate.

In high school, with the encouragement of one particular teacher, Cisneros improved her grades and worked for the school literary magazine. Her father encouraged her to go to college because he thought it would be a good way for her to find a husband. Cisneros did attend college, but instead of searching for a husband, she found a teacher who helped her join the famous graduate writing program at the University of Iowa. At the university’s Writers’ Workshop, however, she felt lonely-a Mexican American from a poor neighborhood among students from wealthy families. The feeling of being so different helped Cisneros find her “creative voice”.

“It was not until this moment when I considered myself truly different that my writing acquired a voice. I knew I was a Mexican woman, but I didn’t think it had anything to do with why I felt so much imbalance in my life, but it had everything to do with it! That’s when I decided I would write about something my classmates couldn’t write about.”

Cisneros published her first work, The House on Mango Street, when she was twenty-nine. The book talks about a young Mexican American girl growing up in a Spanish-speaking area in Chicago, much like the neighborhoods in which Cisneros lived as a child. The book won an award in 1985 and has been used in classes from high school to graduate school level. Since then, Cisneros has published several books of poetry, a children’s book, and a short-story collection.

1.Which of the following is TRUE about Cisneros in her childhood?

A. She had seven brothers.

B. She felt herself a nobody.

C. She was too shy to go to school.

D. She did not have any good teachers.

2.The graduate program gave Cisneros a chance to ________.

A. run away from her family

B. develop her writing style

C. make a lot of friends

D. search for a husband

3.According to Cisneros, what was the key factor in her success?

A. Her feeling of being different.

B. Her training in the Workshop.

C. Her childhood experience.

D. Her early years in college.

4.What do we learn about The House on Mango Street?

A. It is quite popular among students.

B. It is a book of poetry written by Cisneros.

C. It wasn’t a success as it was written in Spanish.

D. It won an award when Cisneros was twenty-nine.
