Question

【題目】 Imagine having an ear made out of an apple. It seems like a crazy idea from a horror movie. 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(器官) in labs to replace our old ones. But it is a hard job. For example, liver cells(肝細(xì)胞) can grow in a lab, but the cells still need things like blood vessels(血管)to actually work. These things have to grow inside a scaffold (支架).

In the past, scientists have used man-made materials, animal parts and even dead people as scaffolds. 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 scaffold.

They first cut an apple into the shape of an ear. Then they used a special way to take out the apple's cells and make it a scaffold. The team then added human cells to the apple, and watched it grow.

“You can implant these scaffolds 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 took over the pieces of apple.

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

He says that the lower petals could be perfect for repairing skin. And asparagus(蘆筍) could fix a broken spine(脊柱).

Now, Pelling and his team are trying hard to put these crazy ideas into reality.

【1】Pelling’s idea of man-made ear seems crazy because he used _______ as scaffolds.

A.animal partsB.dead peopleC.man-made materialsD.ordinary apples

【2】The underlined word “implant” in Paragraph 7 probably means _______.

A.pickB.putC.produceD.protect

【3】From the last three paragraphs, we can infer that Pelling will experiment with other fruit, plants or vegetables _______.

A.to make human earsB.to repair burnt skin

C.to fix a broken spineD.to make human body parts

Answer 1

【答案】

【1】D

【2】B

【3】D

【解析】

本文講述了加拿大生物物理學(xué)家安德魯·佩林用蘋果來(lái)培育人類耳朵。這是一項(xiàng)艱難的工作。過(guò)去，科學(xué)家們使用人造材料、動(dòng)物器官甚至死人作為支架。事實(shí)證明，這既困難又昂貴。佩林和他的團(tuán)隊(duì)發(fā)現(xiàn)，蘋果是一種廉價(jià)容易于使用的支架。他們把蘋果切成耳朵的形狀。然后用一種特殊的方法把蘋果細(xì)胞取出來(lái)做成支架。然后，將人類細(xì)胞添加到蘋果中，并觀察其生長(zhǎng)。把這些支架植入人體，人體會(huì)輸送細(xì)胞和血液，讓這些東西活下來(lái)。研究小組將蘋果支架植入一只活老鼠體內(nèi)，老鼠的細(xì)胞慢慢地占據(jù)了蘋果碎片�，F(xiàn)在佩林正在考慮用其他的水果、植物或蔬菜，現(xiàn)在，佩林和他的團(tuán)隊(duì)正努力將這些瘋狂的想法變成現(xiàn)實(shí)。

【1】細(xì)節(jié)理解題。根據(jù)“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.”可知是使用普通的蘋果作為支架，故選D。

【2】詞義猜測(cè)題。pick挑選；put放置；produce生產(chǎn)；protect保護(hù)；根據(jù)“You can implant these scaffolds into the body, and the body will send in cells and a blood supply and actually keep these things alive.”可知此處是把支架放進(jìn)身體里，所以此處是“放入”，故選B。

【3】推理判斷題。根據(jù)“He says that the lower petals could be perfect for repairing skin. And asparagus(蘆筍) could fix a broken spine(脊柱).”可知是身體的相關(guān)器官，所以用水果等制造人體器官，故選D。
