【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 manmade 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 out 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 shape of flower petals could be perfect for repairing skin. And asparagus(蘆葦) 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 manmade ear seems crazy because he used ________ as scaffolds.
A.animal partsB.dead people
C.manmade materialsD.ordinary apples
【2】The underlined word “implant” in Paragraph 7 probably means ________.
A.pickB.putC.produceD.protect
【3】Which is the right order of making an ear out of an apple according to the passage
a. Put the apple scaffold inside a mouse.
b. Add human cells to the apple scaffold.
c. Cut an apple into the shape of an ear.
d. Make the apple ear a scaffold.
e. Take out the apple’s cells in a special way.
A.abcdeB.bedaeC.cedbaD.cdaeb
【4】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
【答案】
【1】D
【2】B
【3】C
【4】D
【解析】
短文大意:本文是新聞類閱讀,介紹了加拿大生物物理學(xué)家安德魯·佩林計劃用蘋果來種植耳朵的實驗,他甚至設(shè)想用水果、蔬菜來制造其他人體器官。
【1】考查細節(jié)理解。根據(jù)開頭“Imagine having an ear made out of an apple. It seems like a crazy idea from a horror movie想象一個蘋果做成的耳朵。這似乎是恐怖電影里的瘋狂想法”,可知是因為他使用普通的蘋果作為支架,故選D。
【2】考查詞義理解。pick撿;put放;produce生產(chǎn);protect保護。根據(jù)后文的舉例“The team put the apple scaffold inside a living mouse研究小組將蘋果支架植入一只活老鼠體內(nèi)”,可知本句“implant”意思是“放置put”,故選B。
【3】考查細節(jié)排序。a. 把蘋果支架放在老鼠體內(nèi)。b. 將人類細胞添加到蘋果支架上。c. 把蘋果切成耳朵的形狀。d. 把蘋果穗做成支架。e. 用特殊的方法取出蘋果細胞。根據(jù)文章第六段和第八段:先把蘋果切成耳朵的形狀;再用特殊的方式取出蘋果的細胞;接著把切成耳朵的蘋果做成器官;然后把人體細胞加人到蘋果支架;最后把蘋果耳朵植入小白鼠體內(nèi);可知c-e-d-b-a順序正確,故選C。
【4】考查推理判斷。根據(jù)第二段第二句“He thinks fruit and vegetables can be used to cheaply repair human body parts in the future. 他認為,未來可以用水果和蔬菜來廉價修復(fù)人體器官”和倒數(shù)第二段“He says that the shape of flower petals could be perfect for repairing skin. And asparagus could fix a broken spine花瓣的形狀可以完美地修復(fù)皮膚。蘆筍可以修復(fù)斷了的脊椎”,可知他想用水果蔬菜來造人體器官,to make human body parts(制作人體器官)符合題意,故選D。

【題目】Young Inventor Creates Plastic from Fish Scales
Lucy Hughes, a 24-year-old English inventor, has used fish skin and scales(鱗)to create a new kind of plastic that will break down in about six weeks. Her invention won 2019 James Dyson Award, which was created by the famous English inventor James Dyson to encourage students to try to use their creativity to solve problems in the real world.
Lucy Hughes studied how to design products at the University of Sussex in England. As a designer, she knew a lot about how wasteful many products are. Plastic bags, for example, are often used once for a short time and then thrown away. She decided to challenge herself to make something out of waste instead
The University of Sussex isn't far from the coast. Ms. Hughes spent some time studying the fishing business and the waste from fish that were thrown away. After some tests, she decided that the fish skin and scales seemed like the most likely parts for her product. She tried more than 100 different experiments before getting things just right. Ms. Hughes called her finished product "MarinaTex". It solves two problems: the single-use plastic and fish waste.
MarinaTex is clear and feels like plastic, but it's stronger than normal plastic that is of the same thickness. It is also cheap to make since it's made from fish waste. The process of making MarinaTex also doesn't use much energy. Most importantly, MarinaTex doesn't take hundreds of years to break down. On its own, it breaks down in four to six weeks.
For winning the contest, Ms. Hughes will earn f,30, 000. Her school will get f,5, 000. She is looking forward to moving ahead with her idea. She hopes the award money will help her with the process of getting MarinaTex into use as quickly as possible. She thinks that one of the best uses for MarinaTex will be in some kinds of food packaging.
【1】What did Lucy Hughes create?
【2】How many experiments did Lucy Hughes try?
【3】What problems does MarinaTex solve?
【4】What is Paragraph 4 mainly about?
【5】How will Lucy Hughes possibly spend the award money?

【題目】 Farmers' Harvest (收獲) Festival in China started from 2018. It is the first festival for farmers. The festival falls on the Autumnal Equinox (秋分) each year. And the Autumnal Equinox is usually between September 22nd and 24th, during the harvest season.
As we all know, China has the largest population all over the world. In the past, it was difficult to feed the people.

The festival shows that our government is paying more attention to agriculture and farmers' life. It will greatly encourage farmers. China has a long history of agriculture. The Farmers' Harvest Festival helps to show China's long farming culture to the world. It also improves the cultural self-confidence (文化自信心) and national pride (民族自豪感).
The festival is especially created for farmers, so they think of their own ways to celebrate it. During the festival, many different kinds of activities are held across the country, such as folk culture performances, food tasting and so on.

【題目】Dog’s Best Friend
Jarrett Little was road testing his mountain bike outside of Columbus, Georgia, when his riding partner, Chris Dixon, stopped suddenly. Something nearby moving among the trees had caught her attention. It turned out to be a sandy-colored five-month-old dog.
“He was really thin, and had a broken leg,” Little told CBS News. The cyclists fed the friendly dog and shared their water. They also quickly realized that the dog was coming with them, although they had no idea how. They were more than seven miles from downtown and riding bikes. “We couldn’t leave him,” Little said. “Out there next to the Oxbow Meadows, he was going to end up as alligator (短吻鱷) food.”
Little, a 31-year-old business owner, had an idea. He carefully picked up his new friend and put the 38-pound dog’s back legs into the pockets of his cycling shirt. Then he placed the dog’s front legs over his shoulders.
“He was hurt, so he wasn’t trying to fight,” Little says. “He was also happy that we were there, touching him, and hadn’t taken off on him.”
Their 30-minute ride into town ended at a bike store, where they got more water and food for the dog. “That was when Andrea Shaw, a company worker, happened by. The dog went straight to her, smelling and “l(fā)oving on her,” says Dixon. Shaw was touched and, after learning what had happened, decided to keep the dog.
Shaw called him Columbo after the town where they’d met and planned an operation on his leg. Today, Columbo is living the high life on a farm with a horse and a six-year-old boy to keep him company. As Dixon said, “He is really the luckiest dog alive.”
【1】Why did Dixon stop suddenly during the road testing?
A.She noticed something moving among the trees.
B.She had cycled seven miles and wanted to rest.
C.She met some other riding partners by chance.
D.She wanted to share some water with Little.
【2】What can we learn about the dog?
A.He is unfriendly to people.
B.He is kept happily on a farm.
C.He weighed about 31 pounds.
D.He ended up as alligator food.
【3】According to the passage, the dog’s best friend is .
A.the alligatorB.the humanC.the horseD.CBS News
