Question

【題目】 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（細胞）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.

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

【答案】

【1】A

【2】A

【3】B

【4】D

【5】C

【解析】

這篇短文主要講述了加拿大科學家Andrew Pelling用廉價的材料來生產人身體的某一部分，已經試驗成功的是用蘋果來制作一個人體的耳朵，后期還會用更多的植物來制作各種人類的器官和組織，這有利于降低醫(yī)療成本。

【1】細節(jié)理解。body and organs身體和器官；biology and organ生物學和器官；physic and body物理與身體； biology and physics生物學與物理學。根據文中“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” 他認為未來水果和蔬菜可以用來廉價地修復人體部位�？茖W家們一直試圖在實驗室里培育器官來取代我們的舊器官�？芍�，Andrew Pelling是研究身體和器官的。故選A。

【2】細節(jié)理解。Fruits.水果；Animals.動物； dead people死人；man-made人造的。根據文中“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，佩林和他的團隊發(fā)現蘋果是一種廉價易用的支架，他們首先將蘋果切成耳朵形狀�？芍�，用水果做支架。故選A。

【3】細節(jié)理解。根據文中“They first cut an apple into the shape of an ear. Then they used a special way to take out the apple’s cells（細胞）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，他們首先將蘋果切成耳朵形狀。然后他們用一種特殊的方法取出了蘋果的細胞，并將其制成支架，研究小組隨后將人類細胞加入蘋果中，并觀察其生長。將這些支架植入人體內。可知順序為：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。根據題意，故選B。

【4】細節(jié)理解。根據文中““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，人體就會輸送細胞和血液供應，并使這些東西存活下來。選項D“ By sending in cells and a blood supply” 通過輸送細胞和血液。故選D。

【5】標題歸納。Scaffolds and cells支架和細胞； Organs and cells器官和細胞；Organs Made of Apples由蘋果制成的器官； Scientists and apples科學家和蘋果。根據文中“Imagine having an ear made out of an apple. It seems like a crazy idea. But it could happen in the near future.” 想象一下有一個蘋果做的耳朵。這似乎是個瘋狂的主意。但這可能在不久的將來發(fā)生�？芍�這篇短文的表示提示“水果做的器官”。故選C。
