Question

【题目】 Imagine having an ear made out of an apple. It seems like a crazy idea. But it could happen in the near future.

Canadian biophysicist Andrew Pelling used an apple to grow a human ear. He thinks fruit and vegetables can be used to cheaply repair human body parts in the future.

Scientists have been trying to grow organs in labs to replace our old ones. But it‘s a hard job. In the past, scientists have used man-made materials, animal parts and even dead people as scaffolds（支架）. But that has proved to be difficult and expensive.

Pelling and his team, however, found the apple to be a cheap and easy-to-use scaffolds.They first cut an apple into the shape of an ear. Then they used a special way to take out the apple‘s cells（细胞）and make it a scaffold. The team then added human cells to the apple, and watched it grow. “You can implant（移植）these scaffold into the body, and the body will send in cells and a blood supply and actually keep these things alive, ” Pelling said during a Ted Talk speech.

The team put the apple scaffold inside a living mouse and the mouse’s cells slowly take over the pieces of the apple.

Now Pelling is thinking of the other fruit, plants or vegetables to use.

④Add human cells to the apple scaffold.

A.①④②③B.②①④③C.②①③④D.④①③②

【4】How will the body keep the implanted scaffolds alive?

A.By repairing the scaffolds.B.By replacing the scaffolds.

C.By taking over the scaffolds.D.By sending in cells and a blood supply

【5】What‘s the best title of the passage?

A.Scaffolds and cellsB.Organs and cells

C.Organs Made of ApplesD.Scientists and apples

【5】C

【解析】

这篇短文主要讲述了加拿大科学家Andrew Pelling用廉价的材料来生产人身体的某一部分，已经试验成功的是用苹果来制作一个人体的耳朵，后期还会用更多的植物来制作各种人类的器官和组织，这有利于降低医疗成本。

【1】细节理解。body and organs身体和器官；biology and organ生物学和器官；physic and body物理与身体； biology and physics生物学与物理学。根据文中“He thinks fruit and vegetables can be used to cheaply repair human body parts in the future. Scientists have been trying to grow organs in labs to replace our old ones” 他认为未来水果和蔬菜可以用来廉价地修复人体部位。科学家们一直试图在实验室里培育器官来取代我们的旧器官。可知，Andrew Pelling是研究身体和器官的。故选A。

【2】细节理解。Fruits.水果；Animals.动物； dead people死人；man-made人造的。根据文中“Pelling and his team, however, found the apple to be a cheap and easy-to-use scaffolds.They first cut an apple into the shape of an ear” 然而，佩林和他的团队发现苹果是一种廉价易用的支架，他们首先将苹果切成耳朵形状。可知，用水果做支架。故选A。

【3】细节理解。根据文中“They first cut an apple into the shape of an ear. Then they used a special way to take out the apple’s cells（细胞）and make it a scaffold. The team then added human cells to the apple, and watched it grow. “You can implant（移植）these scaffold into the body,”可知，他们首先将苹果切成耳朵形状。然后他们用一种特殊的方法取出了苹果的细胞，并将其制成支架，研究小组随后将人类细胞加入苹果中，并观察其生长。将这些支架植入人体内。可知顺序为：②Cut an apple into the shape of an ear.；①Make the apple a scaffold.；④Add human cells to the apple scaffold.；③Implant this scaffold into the human body。根据题意，故选B。

【4】细节理解。根据文中““You can implant（移植）these scaffold into the body, and the body will send in cells and a blood supply and actually keep these things alive,”Pelling said during a Ted Talk speech.”可知，人体就会输送细胞和血液供应，并使这些东西存活下来。选项D“ By sending in cells and a blood supply” 通过输送细胞和血液。故选D。

【5】标题归纳。Scaffolds and cells支架和细胞； Organs and cells器官和细胞；Organs Made of Apples由苹果制成的器官； Scientists and apples科学家和苹果。根据文中“Imagine having an ear made out of an apple. It seems like a crazy idea. But it could happen in the near future.” 想象一下有一个苹果做的耳朵。这似乎是个疯狂的主意。但这可能在不久的将来发生。可知这篇短文的表示提示“水果做的器官”。故选C。
