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 transfer（SCNT）, 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.

   Would you buy a car that can release calming smells into the air when you are stuck in heavy traffic? Would you buy a robot that smells like a human being?

Many people have seen the 3-D computer-made environments of virtual reality（虚拟现实）. Now these virtual worlds will not just look and sound real. Researchers have created VR environments that even smell like the real ones. With the new technology, users open a virtual door and step into a new environment, like a rainforest. After they enter this virtual world, special equipment releases forest-like smells into the air to make the experience feel more real.

Suzanne Fisher-Murray said, “It is a really wonderful experience that you have because you’re exploring this environment and you have smells with it.”

In the United States, Smell-O-Vision was designed to provide smells during the showing of a movie. The Smell-O-Vision system was once popular in the 1960s. Now, Emanuela Maggioni says it is close to becoming popular again. “It connects emotions and memories with the sense of smell,” Maggioni said. “It is unbelievable what we can do with the technology.”

The uses of smell technology are not just limited to films and the performing arts. Researchers showed a computer program where users could imagine themselves driving a car. The system included a special smell-spraying machine. Dmitrijs Dmitrenko said, “We want to deliver the smell of lavender(薰衣草) every time the person drives over the speed limit. We choose lavender because it’s a very calming smell.”

Scientists are experimenting with smells instead of sounds or image-based alerts on telecommunications equipment. And businessmen have already used smells to influence people’s behavior. “Not only in stores, but also in other places you can create and stimulate(刺激) immediate purchase,” Maggioni said. “So you’re in a library and when you smell coffee you will unconsciously have the need to drink a coffee.”

【小题1】Using smell technology, researchers make VR environments ________.

A．have a smell of a rainforest

B．even smell like the real ones

C．look like a 4-Denvironment

D．frighten people with a virtual world

【小题2】The example of Smell-O-Vision proves that________.

A．America is the first to use smell technology

B．cinemas are the most suitable places for the sense of smell

C．smell technology has been used before

D．it is out of date to use smell-spraying devices

【小题3】How is smell technology used by businessmen？

A．To make buyers understand salesmen better.

B．To remind people of their unrealistic purchase.

C．To help customers choose their favorite goods.

D．To stimulate people to buy things.

【小题4】What is the main idea of the passage？

A．The new developments of smell technology.

B．A major breakthrough of VR technology.

C．The sense of smell in human communication.

D．The advanced smell-spraying machines.

Several Jobs That Will Be Automated By Artificial Intelligence(AI) And Robots
Translator
Image recognition software and voice recognition software are bringing some major advances to language translation．Applications like Google’s Word Lens can translate words from signs and documents in real time and there are a lot of translation apps that allow you to type in a word or phrase and will translate it for you．
Some will even speak the phrase for you and raw word-to-word translation will be fully automated soon．
Fast food workers
Automated ordering booths have already made their way into a few McDonald’s restaurants around the world，and cooking positions could be removed next．The booths probably can’t handle customer service problems well，so televideo systems could bring in an office employee to deal with complaints．
Field technician
New advances in the Internet of Things could make this work obsolete.
Low-cost sensors combined with high availability cellular／satellite communications and cloud technology are being started to automate and alarm these sites, and can be checked and maintained from a desktop or mobile device.
Sales representative
But, e-commerce is changing how we make purchasing decisions, especially those where there isn’t much differentiation among the major competitors.
If you’re selling a high-differentiation product and／or a high-price, low-volume product you have some job security, but if you’re selling a high-volume, low-differentiation product, you better start polishing your resume, said Doug Camplejohn, CEO of Fliptop. “These kind of product sales are all moving online.”
【小题1】What can Google’s Word Lens do?

A．Translate by image and voice recognition software.

B．Speak the phrase or word for you.

C．Make real-time translation.

D．Allow you to type in a word or phrase.

【小题2】What can we infer from the second part?

A．All the restaurants own automated ordering booths.

B．Service problems can’t be handled automatically.
