【題目】C

Researchers are now using three-dimensional, or 3D printing to create models of the human heart to help heart specialists. The heart doctors can use the models to better help patients before an operation.

Surgeons regularly use digital images to explore the heart in close detail. But no two human hearts are alike. This led Matthew Bramlet to create exact heart models from those images. Dr. Bramlet is a pediatric or children's heart expert at the University of Illinois College of Medicine. He says the 3-D models show information he cannot get any other way.

A 3-D printer uses images from a digital display to create a physical model of a human heart. Matthew Bramlet says doctors can use the model, in his words, "to understand the anatomy(解剖) for the first time."

Pictures from medical tests like CAT scan or MRI are sent to a 3-D printer to create a heart in a plaster or clay form. The printer then constructs the heart, thin layer by thin layer. Dr. Bramlet says the model matches the real heart in every detail.

Dr. Bramlet has built model hearts for different kinds of heart operations. All of the operations were successful. In his first case, digital images showed only one tiny hole in a baby's heart. But, the 3-D printed model showed several defects or problems that the baby was born with. Dr. Bramlet says those defects could not be seen easily in the images. The heart surgeon was able to change the type of surgery for the patient based on the 3-D model. He added that 3-D heart models saves time during heart operations.

Matthew Bramlet continues to research the technology. He is working with the National Institutes of Health to build a 3-D library that includes heart models and images that others can use.

【解析】文章主要介紹的是使用3D打印技術(shù)打印心臟模型，來指導(dǎo)外科醫(yī)生更準確地挽救病人的生命。使用3D打印技術(shù)制作的心臟模型更為逼真，能夠讓醫(yī)生更全面地分析患者的病情。從而對病情做出更加準確的判斷。

【1】B 細節(jié)理解題。根據(jù)第一段“to create models of the human heart to help heart specialists. The heart doctors can use the models to better help patients”可知，使用3D技術(shù)來打印心臟模型是為了幫助醫(yī)生更好地幫助病人。

【2】A 細節(jié)理解題。根據(jù)第二段“But no two human hearts are alike. This led Matthew Bramlet to create exact heart models from those images.”可知，沒有兩個人的心臟是完全一樣的，這促使Matthew Bramlet產(chǎn)生了創(chuàng)造心臟模型的念頭。

【3】D 猜測詞意題。根據(jù)”one tiny hole in a baby's heart...the 3-D printed model showed several defects or problems that the baby was born with.”醫(yī)生通過3D打印技術(shù)發(fā)現(xiàn)嬰兒的心臟有幾處先天性缺陷，劃線詞與problems并列。

【4】C 細節(jié)理解題。根據(jù)第四段“Pictures...are sent to a 3-D printer to create a heart in a plaster or clay form. The printer then constructs the heart, thin layer by thin layer.”可知，來自CAT和MRI的照片發(fā)送到3D打印機中，打印機使用這些照片來制作心臟模型。B、C與題意無關(guān)。

【5】A 主旨大意題。根據(jù)第一段“Researchers are now using three-dimensional, or 3D printing to create models of the human heart to help heart specialists.”和第二段“the 3-D models show information he cannot get any other way”與第三段“doctors can use the model to understand the anatomy(解剖) for the first time”及第四段“the model matches the real heart in every detail”可知文章主要講的是3D打印技術(shù)在醫(yī)學(xué)上的使用。

【題目】Dolphins call out the specific names of loved ones when they become separated, a study finds．Other than humans, they are the only animals known to do this, according to the study．The big difference with dolphins is that these communications consist of whistles（鳴叫）, not words．

Earlier research found that dolphins have a “signature whistle” that would be somewhat like human shouting, “Hey everybody! I’m an adult healthy male named George, and I mean you no harm．”

The new finding is that dolphins also say the names of certain other dolphins．“Animals produced copies of the same sound when they were separated from a close partner．This supports our belief that dolphins copy another animal’s signature whistle when they want to reunite with that animal,” Stephanie King, who led the study, says．

King and her colleagues collected acoustic（聲音的）data from wild dolphins around Sarasota Bay, Florida, from 1984 to 2009．The researchers also studied four adult male dolphinshousedat the Seas Aquarium, also in Florida．

Those males are adults that keepers named Calvin, Khyber, Malabar and Ranier, all of whom, as well as all of the wild ones, developed their own signature whistles that served as names in communication with other dolphins．

“A dolphin uses its signature whistle to broadcast its identity and announce its presence．The signature whistles allow animals to identify one another over long distances and allow animals to recognize one another and to join up with each other,” King explains．“Dolphin whistles can be heard up to 20km away, depending on water depth and whistle frequency（頻率）．”

The researchers said dolphins copy the signature whistles of loved ones, such as a mother, when the two are separated．These “names” are always used in positive situations, and are only directed toward loved ones．

While researchers are often unwilling to apply the word language to non-human communications, dolphins clearly have a very complex communication system．

【1】The underlined word “housed” in Paragraph 4 probably means “_________”．

A. raised B. saved C. discovered D. hunted

【2】Which of the following plays a part in whether dolphin whistles can be heard over a distance?

A. The dolphin’s identity．

B. The water temperature

C. The whistle frequency．

D. The dolphin’s age．

【3】When do dolphins copy the signature whistles of loved ones?

A. When there is a fight．

B. When their keeper comes．

C. When they are apart．

D. When they are hungry．

【4】Where is the passage probably taken from?

A. A magazine about scientific advances．

B. A website about various animals．

C. A report on animal acoustics．

D. An essay about the relationship between humans and animals．

【題目】My 18-month-old son, Adam, called from the front door．“Look, Mama! Doggie!” I dropped what I was doing and stuck my head out the door．Brandy, our next-door neighbor’s 11-year-old dog, was over again．“Go away!” I shouted．

Brandy’s owner had died about a month earlier．The woman’s family had emptied the house and stuck a “For Sale” sign in the front yard, but the family had left old Brandy behind．For weeks, she’d been wandering around the neighborhood．

It wasn’t that I disliked dogs or anything like that．I just didn’t think about them very much．I never had a dog growing up and had never thought to get one．

Brandy went away and I stayed outside with Adam．Then the phone rang．I went inside to take the call．When I came back, Adam was gone．I searched the yard, front and back, then the basketball court and public pool．No trace of him．I was so nervous that I ran home and called the police, then my husband．

Police searched the neighborhood．Suddenly I heard another sound: a dog barking．“It’s coming from the woods,” one of my neighbors said．We followed the barking to a wooded cliff（懸崖）．There we found my son, and he was just inches away from the edges of the cliff, fast asleep．Brandy was beside him, leaning（倚靠）against him to keep him away from the edge．When I picked Adam up, Brandy sank down on her side, breathing quickly．She must have been holding Adam there for hours!

I thanked the police and brought Adam and Brandy back to our house．She hesitated a moment on our doorstep, no doubt remembering the time I’d driven her away．

“Come on, girl,” I said．“This is your home now．” Brandy stepped in, and once she saw she was really welcome, she relaxed and lay down on the floor just inside the door．She’d done a great thing, and I wondered if she knew it ．She’d certainly touched me in a way that no animal ever had．What a pity a dog like Brandy had been left behind!

【1】What is the correct order for the events in the story about Brandy?

b．She stepped into the woman’s house．

c．She appeared at the woman’s front door．

C. c, d, b, a D. a, c, d, b

【2】What did the woman do when she first saw Brandy?

A. She gave her some food．

B. She drove her away．

C. She took her home．

【3】Why did the woman call the police?

A. Her son was lost

B. Brandy was gone．

C. Brandy appeared in her yard．

D. She got a scary call．

【4】How were they able to know that the woman’s son was near the cliff?

A. By searching the neighborhood．

B. By hearing a dog barking．

I like eating fruit and vegetables what are of great benefit to our healthy. Not only do they prevent us from falling into ill, but they help us lose weight. I used to hate vegetables, but follow the doctor’s advice, I gradually kicked the bad habit. Just as an old saying going, “An apple a day keeps the doctor away”. However, there are still many children dislike fruit and vegetables. On contrary, influenced by this or that kind of advertisement, many were crazy about junk food. Consequently, they become weaker and weaker instead of getting strong. In my opinion, we must take action to change them.
