初中英语说明文阅读理解

Imagine having an idea, drawing it on paper, bringing it to a store and seeing it turned into an object. This is now possible with the help of 3D printers. Such machines were once used just by universities and big companies, but now, stores with 3D printing services are appearing around the United States.
Bryan Jaycox and his wife opened The Build Shop LLC in Los Angeles two years ago. The Jaycoxs offer 3D printing classes and services for anyone who is interested.
“I think 3D printing is going to be huge. It’s going to have a huge influence on society as a whole.” says KiChong Tran, one of the students in a recent class. He plans to open a 3D printing business in Cambodia (柬埔寨).
3D printing services are coming into American people’s life. The UPS Store is a nationwide retailer (零售商) that provides copying and other services. The UPS Store recently put 3D printers in three of its independently-owned stores. Burke Jones owns one of the stores in San Diego.
“The demand has been amazing. There has been a lot of interest from people. It’s been much more than I would have imagined.”
The UPS Store plans to add 3D printers in three more stores.
For $11, someone used a 3D printer to produce two small plastic parts as part of a knuckle (指节) for a hand. He works for the company which is testing finger prosthetics (假肢). He says the same–day or next-day printing services will speed up testing of parts and get them to patients faster.
Staples, an American store, is selling 3D printers on its website for as low as about $1,300. As with any technology - experts expect the printing speed to increase and the price to go down.
Bryan Jaycox requires $15 an hour to print an object. He also sets the price depending on the size of the object and up to $50 an hour for design and labor services.
Mr Jaycox thinks that within five years, 3D printing technology could become more user friendly. But KiChong Tran says even today’s technology can make a difference in a developing country like Cambodia.
“With 3D printing you can give them tools, so they are responsible more for their own development and they learn skills beyond just like learning English and becoming a tour guide or something like that. You can actually create things that give value to the world.”
He says it’s not just Cambodia but anywhere where there is a 3D printer, it can turn a good idea into reality.

What does the underlined part mean in this passage?

B．There is no 3D printing business in Cambodia.

D．3D printing plays the most important role in daily life.

Which part of the world has the most nearsighted students? Just look around you–it’s East Asia. Nine in ten school leavers in major East Asian cities are nearsighted, according to the BBC. Experts say books and video games are not to blame. East Asian students, they say, aren’t getting enough sunlight.
People become nearsighted because their eyeballs grow out of shape and light entering their eyes cannot focus correctly. The body can produce a chemical called dopamine (多巴胺) to stop eyeballs from changing shape. And guess what scientists have just discovered? Sunlight can help our bodies produce more dopamine, reported AFP.
According to the study, primary school students in Singapore spend only 30 minutes outdoors every day; in Australia, by contrast, kids spend about three hours a day outside. As a result, fewer children in Australia are nearsighted–only 10 percent, compared with 90 percent in Singapore.
“Children in East Asia basically go to school... go home and stay inside. They study and they watch television,” Ian Morgan of the Australian National University told AFP.
But being a bookworm or a couch potato does not directly harm the eyes, added Morgan. “As long as they get outside, it doesn’t seem to matter how much study they do,” he explained. “There are some kids who study hard and get outside and play hard and they are generally fine. The ones who are at major risk are the ones who study hard and don’t get outside. As a result of massive (巨大的) educational pressures and the construction (构成) of a child’s day, the amount of time they spend outside in bright light is minimized.”
Experts suggest children should stay outside for two to three hours every day. This can include time spent in the playground and walking to and from school.
Which of the word has the similar meaning as the underlined phrase “nine in ten”?

A．many

B．few

C．some

D．most

What is the main reason for the large number of nearsighted students in East Asia, according to scientists?

A．Too much reading or gaming.	B．Lack（缺少）of sunlight.
C．Genetic reasons.	D．Lack of exercise.

What can we conclude from Paragraph 2?

A．Dopamine is a chemical that causes eyeballs to grow out of shape.

B．Dopamine can stop light entering the eyes from focusing correctly.

C．Spending time in the sun can make the loss of dopamine in the body.

D．The more dopamine a person has in their body, the better eyesight he or she has.

According to Morgan, what kind of people are most likely to suffer from nearsightedness?

A．Those who like watching TV.

B．Those who take exercise regularly.

C．Those who study hard and play hard outdoors.

D．Those who stay indoors studying all day
