2 . What if a rollercoaster ride looked like this: no rails, no trains, just a chair on a mechanical arm (机械手臂) and a pair of glasses—VR glasses meaning virtual reality? That’s how it is in Nanchang, China, where a new amusement park relies entirely on digital entertainment.

Compared with a traditional theme park, this VR theme park takes up smaller space and much less time to build, but it brings visitors similar playing experience. The park uses VR for a variety of attractions, including the roller coaster ride, a musical video game where you have to hit the right notes, and a shooter in a completely unreal environment. It really gives you the feeling of reality.

The park wants to invest in a future technology and hopes to keep people’s fascination with virtual reality of life. For the technology, it is still highly experimental. What we want to do with virtual reality is to experience things in and beyond reality, but in fact the VR we can experience right now has a lot of limits. For example, although on the visual front, we can say we’ve broken past reality in our visual experience, there’s still a lack of physical feedback, meaning we can see the virtual world around us but we can’t feel them. That limits the technology’s appeal from many applications.

For now, one of its main uses is in professional training. For example, for pilots in a Boeing VR simulator(模拟器), a real touchable interface is combined with a virtual world outside. Some significant development is still needed before we can virtually wander around in our houses, go for a walk without leaving the house or actually hold a product in our hands before buying it online. Nanchang hopes to become a significant VR player in the future not just with digital rollercoasters.

1. What can be an advantage of the VR theme park over traditional ones?

A．Its lower cost.	B．Its shorter building time.
C．Its larger area.	D．Its more exciting attractions.

2. What is the third paragraph about?

A．The limits of the present VR technology.

B．The uses of VR technology in the future.

C．The vivid experience of playing a VR roller coaster.

D．The experiments done to improve VR technology.

3. What can be done now with the aid of VR technology?

A．Playing a musical instrument.	B．Walking out without leaving the house.
C．Training pilots in a simulator.	D．Touching a product when shopping online.

4. What’s the best title for the text?

A．A Roller Coaster without Rails

B．Nanchang: the Next King of VR Technology

4 . China became the first country to clone a monkey using non-reproductive cells, reducing the need to keep lab monkeys and paving the way for more accurate, effective, and affordable animal tests for new drugs .

By December of 2017, Chinese scientists had created two clone macaques named "Zhong Zhong" and "Hua Hua" by nuclear transferring of somatic cells -- any cell in the organism other than reproductive cells. This was the similar technology used to create the famous clone sheep Dolly in 1996.

"Cloning a monkey using somatic cells has been a world-class challenge because it is a primate（灵长类）that shares its genetic makeup, therefore all of its complexity, with humans." Pu Muming said.

"For drug and other lab tests, scientists have to purchase monkeys from all over the world, which is costly, bad for the environment and produces inaccurate results because each monkey might have different genes, " Pu said.

"By cloning monkeys using somatic cells, we can mass produce large numbers of genetically identical（相同的）offspring in a short time, and even change their genes to suit our needs," he added. "This can save time, cut down experiment costs, and produce more accurate results, leading to more effective medicine."

"This achievement will help China lead the world research in an international science project related to neural（神经的）mapping of primate brains，," he said. However, bio labs from the United States, Japan, and European countries are also very able, and they will quickly catch up to China after the monkey cloning technology is made public, Sun added."This means we have to innovate（创新）continuously and work extra harder this year to stay ahead," he said.

1. What is special about China's cloning monkey?

A．It transferred cells in the lab.

B．Il creates two monkeys at a lime.

C．It adopts a method of embryo splitting.

D．It uses non-reproductive cells.

2. Why do scientists clone monkeys?

A．To keep monkeys from being endangered.

B．To test new medicines on them.

C．To find the side effects of medicines.

D．To find a cure for mental diseases.

3. What Sun said in the last paragraph suggests____

A．they are determined to catch up to America

B．they try to avoid competition from other countries

C．they aren't satisfied with what they have achieved

D．they have to keep the monkey-cloning technology a secret

5 . Several years ago I started riding a bike. At first, I thought it was only a ______ ride. But as I built up strength, my friends encouraged me to try some longer ______. The first one to come along was a 150-mile journey, an event held every year that ______ money to fight cancer.

My focus ______ at that moment. I'd been doubting my body for a whole day. But now I knew — it wasn't the body, but the ______ that would help me reach my goal.
