二、阅读理解：阅读下面的短文，根据文章内容进行判断，正确为“T”，错误为“F”。Passage 1 (教材课文原文)

"The printer did not always manage to spread the plastic evenly, making some of the ribs of the honeycomb structure of the block uneven," reported ARN (Australian Radio Network) to the surprise of no one who has used a 3D printer. But the architects remain optimistic. The first few printed blocks are meant to be test pieces as they improve the process.

It takes about a week to print a 3-meter high block right now. The project's leaders hope to eventually get that down to two hours and finish the first of 12 rooms in a year, and the entire house in less than 3 years.

}

Ultimately, 3D Print Canal House is an architectural research project, one that is very much being conducted in the public eye: you can actually buy tickets to visit the construction site for Euros. The top floors will become more ornate, for example, as newer techniques are incorporated. They'll explore the possibilities of 3D printing, like the honeycomb walls or an entire room recycled, redesigned, and built anew. Nobody's going to move into a 3D printed house soon, but, if anyone ever does, something might be learned from this experiment by the canal.

1. According to the passage, the 3D printer can type with plastic evenly.

2. This 3D printer printed some blocks to test its work.

3. The project's leaders will finish the entire house in less than 3 years.

4. 3D Print Canal House is printed to live.

5. The canal house will be decorated more.

二、阅读理解：阅读下面的短文，根据文章内容从A、B、C三个选项中选出一个最佳选项。In the grass, a baby duck was hatched (孵化) out in a college biology lab with a backward left foot.

At the time, it probably wouldn’t have survived, if Mike Gary didn’t recommend a proper operation to cut off that bad foot.

-

Months after the healing process, engineers at Novacopy Company produced a 3D printed model that would be used to create a prosthetic (修复的) foot for the duck. Considering that ABS plastics were not flexible enough for this type of exercise, the Novacopy company made a three-dimensionally modeled foot made of silicone, with the hope to create a permanent prosthesis(假肢) for the duck.

It took just 13 hours to produce. This 3D prosthesis demonstrated the 3D technologies can be used not only for human application, but also in foreign subjects such as animals and other medical treatments.

1. Where was the baby duck hatched out回答正确

A. In a college biology lab.

2. What was wrong with the baby duck回答正确

B. It was born with a backward left foot.

3. Could ABS plastics be used to produce a 3D printed model that would be used to create a prosthetic foot for the duck回答正确

A. No, because ABS plastics were not flexible enough.

4. How long did it take to create a permanent prosthesis for the duck回答正确

B. 13 hours.

5. What did the last sentence of this passage indicate回答正确

C. 3D technologies can be used to human, animals and other medical treatments.
