3D printing technology has been advancing at a rapid pace. NASA is looking at uses in space and scientists are researching the technology for 3D printing of organs. But they can now also help us build our dream home. A robot named Frank sits in at the 3D home showroom in Viera. He’s part of an impressive pedigree, as his predecessor constructed the largest 3D printed building. The showroom is for people to get a close look at the emerging technology, according to Jennifer McKinney of Apis Cor. “People can kind of go around and look at the wall samples and see that it’s very similar to traditional concrete masonry block(砌墙块) construction.” McKinney said.
Brevard-based Apis Cor created Frank and is a very non-traditional construction company. They see their new way of building homes extremely current. It solves the problem of supply chain issues and the lack of skilled workers. The process only requires about three people and will take two weeks once Frank and two smart support machines are set up.
Homes will start at $300,000, but the sky’s the limit, as customization(定制) can be done easily. “I like the fact that it’s so durable. In different parts of the country we are seeing storms and tornadoes that went through Kentucky, which are not far from where we live. The room can stand the heavy wind,” Ohio resident Jan Stockton said while visiting.
Traditional home construction sites are usually littered with scraps(废料) and extra material. But Apis Cor says that its 3D home printing process will remove most of that waste. Thus, it’ll be greener and more efficient. “We just print what we need and even if there’s a little bit here and there, we can reincorporate it back into the home,” McKinney said. $7,000 will reserve a 3D printed house before operations start in 2023. The company is focused on building homes here in Florida before their plans to expand across the country.

1.Why is a showroom put in Viera?

A To introduce robot Frank’s background.

B To show people the newest 3D house.

C To explore emerging technologies.

D To build our dream home.

解析：选B。B。推理判断题。根据文章第一段的The showroom is for people to get a close look at the emerging technology可以得知这个展室是为了让人们近距离的接触3D打印房屋技术。故选B。

2.What should Apis Cor do when printing houses?

A Hire skilled workers.

B Prepare support machines.

C Buy a lot of concrete.

D Create a long supply chain.

解析：选B。B。细节理解题。根据文章第二段最后一句的The process only requires about three people and will take two weeks once Frank and two smart support machines are set up可以得知整个过程只需要三个人，但是需要机器人Frank和两台智能辅助设备的支持。故选B。

3.What is the advantage of 3D houses?

A They are not expensive.

B They are very large.

C They are quite strong.

D They are not heavy.

解析：选C。C。推理判断题。根据文章第三段最后一句The room can stand the heavy wind可以得知这个房屋能禁得住大风，所以可推知这个房子很结实“strong”。故选C。

4.Why is the 3D home printing process greener?

A It is littered with scraps.

B It needs extra materials.

C It has no leftovers.

D It focuses on building homes.

解析：选C。C。推理判断题。根据文章最后一段的“We just print what we need and even if there’s a little bit here and there, we can reincorporate it back into the home”可以得知当有剩余的材料的时候，3D打印能重新再次利用这些材料，所以是不会产生废物的，因此更加绿色。故选C。
