【2016高考训练】阅读理解—推理判断题。
Expensive perfumes(香水) come in tiny bottles, but many hide a whale-sized secret.
To perfect a particular smell, perfume-makers often use an ingredient that comes from sperm whales, called ambergris. But using ambergris, which helps a perfume last longer, is strongly opposed by many people who think it is wrong to kill whales just so we can sweet, Joerg Bohlmann is neither a perfumer nor a whale expert, He's a plant biologist at the University of British Columbia in Canada. But his discovery of a new plant gene(基因) might push whales out of the perfume business.
The gene comes from fir trees, found throughout North America and commonly used as Christmas trees. The trees produce a chemical that can be used in perfume in place of ambergris—but with a catch.
“There's a problem that many people wouldn't consider. In the tree, the chemical is mixed with many others. That makes separation a challenge,” Bohlmann says.”It's like trying to isolate sugar from a biscuit.”
This is where science becomes useful. When Bohlmann learned that fir trees produce the ambergris-like chemical, he decided to use his gene know-how to find the instructions for how to make the ambergris-substitute.
Bohlmann found that gene and took it out of the tree cells. Then he did something that might sound strange to someone who doesn't work in genetics: Bohlmann put the gene from the tree into yeast(酵母) cells.
Yeast may sound familiar because it's used to make things like bread, wine and beer. Biologists like to work tith yeast because it easily adopts new genes and changes its features and behavior. When Bohlmann put the fir tree into the yeast, the yeast started making the same chemical that had seen produced by the tree.
Perfumers pay big money for ambergris because it is a fixative, which means it holds a smell in place on a person's body.
“Cheap perfumes smell good in the first hour or so and then everything it gone.” explains Bohlmann. “But expensive perfumes are much more stable. Their smell lasts much longer, for hours or even a day after you apply them.”
The new chemical, made from the tree genes, can be used as a fixative, too. And using yeast to make it is far cheaper than acquiring ambergris.
Bohlmann admits he never thought he'd get into the perfume business. But now, he says, producers have been calling to find out how to use his technology in mew perfumes.
It can be inferred from the passage that if a perfume contains ambergris,
Its user probably supports whale hunting
Its smell will last for about an hour
There will be a whale symbol on hour
It is probably very expensive
The underlined expression “with a catch” in Paragrph 3 means
Being difficult to hold
B. having a hidden problem
C.
needing further testing
D. being too similar
3.
According to the passage, why are yeast cells often used in genetic research?
A. They can take on the characteristics of other genes
B. They can reproduce much faster than other cells.
C. They share some of the qualities of plant genes.
D. They're much cheaper to use than ambergris.
4. What can we learn about Joerg Bohlmann from the passage?
A. He is opposed to whale hunting.
B. He made his discovery during Christmas.
C. He has worked in the perfume industry for many years.
D. He has previously done genetic esearch.

本文是一篇科普说明文。介绍了一种使香水香味持久的物质——龙涎香，因这一物质来自于鲸，所以遭到人们的反对。科学家们发现一些树中的化学物质可以用来取代它，他们利用酵母菌成功制造出了这些化学物质。
D 推理判断题。 根据第二段第二句以及倒数第三段可知，含有龙涎香的香水价格昂贵，故D项正确。
B 词义猜测题。根据第四段中“There's a problem that many people wouldn't consider.” 可知该词组意为”有隐含的问题“， 故选B项正确。
A 细节理解题。根据第七段第二句可知，由于酵母菌容易吸收其他基因，并将目的基因成功表达出来，故常被用于基因工程研究中，故A项正确。
D 推理判断题。根据第二段最后一句及第三段表达的语境可知，Joerg Bohlmann 已经意识到，这些树中某些基因所产生的和其他物质可以被用于香水中以代替龙涎香，但是这些化学物质和其他物质混合在一起，难以分离，故可以断定，Joerg Bohlmann 曾经做过基因研究，故D项正确。
2016高考训练题。阅读理解阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。The Netherlands on Monday introduced its first-ever intelligent bicycle, fitted with electronic devices to help bring down the high accident rate among elderly cyclists in the bicycle-mad country.
Developed for the government by the Netherlands Organization for Applied Scientific Research (TNO), the intelligent bicycle, runs on electricity. A commercial-available bicycle is expected to be on the market in the next two years and should sell for between 1, 700 to 3, 200 euros per bicycle.
The devices on the bike are linked through an onboard computer with a vibrating (震动的) warning system fitted in the bicycle's saddle and handlebars to warn cyclists of the coming danger.
The saddle vibrates when other cyclists approach from behind, while, the handlebars do the same when barriers appear ahead.
"Accidents often happen when cyclists look behind them or get a fright when they are passed at high speed," said Maurice Kwakkernaat, one of TNO's research scientists involved in the project. "The onboard system technology has already been at work in the car industry," he said.
''More and more elderly people are using a bicycle, not only for short distances, but also for longer distances," Dutch Environment and Infrastructure Minister Melanie Schultz van Haegen told AFP. "This type of bicycle is truly needed in the Netherlands because it will help us bring down the number of elderly people who are injured every year and allow them to continue to enjoy cycling," she said.
In the Netherlands, bicycles outnumber the population of 17 million by at least one million and there are some 25,000 km of bicycle path in the country. Those statistics are set to grow as more and more people take to two-wheeled transport, leading to an increased risk of injury.
Last year, 184 cyclists died in the country, of which 124, or 67%, were older than 65, according to the Central Statistics Office. The year before, 200 cyclists died, the majority of victims also being elderly.
The current model weighs 25 kilograms but researchers are working on making the onboard systems smaller.
1. The intelligent bicycle is aimed to ________.
A. protect the environment
B. help reduce traffic pressure
C. popularize the use of bicycles
D. improve safety for elderly cyclists
2. Which part of the intelligent bicycle will vibrate when another cyclist was suddendly found ahead ?
A. The handlebars.
B. The wheels.
C. The saddle.
D. The onboard computer.
3. We can learn from the passage that ________.
A. the elderly ride bicycles wherever they go B. the accident rate among elderly cyclists is high
C. the number of elderly cyclists is decreasing D. the elderly are planning to give up cycling
4. Which is the best title for the passage?
A. A Test Bicycle
B. Elderly Cyclists
C. A Smart Bicycle
D. A Bicycle-mad Country

故事类
As a young boy, I sometimes traveled the country roads with my dad. He was a rural mail carrier, and on Saturdays he would ask me to go with him. Driving through the countryside was always an adventure: There were animals to see, people to visit, and chocolate cookies if you knew where to stop, and Dad did.
In the spring, Dad delivered boxes full of baby chickens, and when I was a boy it was such fun to stick your fingers through one of the holes of the boxes and let the baby birds peck on your fingers.
On Dad's final day of work, it took him well into the evening to complete his rounds because at least one member from each family was waiting at their mailboxes to thank him for his friendship and his years of service.“Two hundred and nineteen mailboxes on my route，” he used to say, “and a story at every one.” One lady had no mailbox, so Dad took the mail in to her every day because she was nearly blind. Once inside, he read her mail and helped her pay her bills.
Mailboxes were sometimes used for things other than mail. One note left in a mailbox read, “Nat, take these eggs to Marian; she's baking a cake and doesn't have any eggs.” Mailboxes might be buried in the snow, or broken, or lying on the ground, but the mail was always delivered. On cold days Dad might find one of his customers waiting for him with a cup of hot chocolate. A young girl wrote letters but had no stamps, so she left a few buttons on the envelope in the mailbox; Dad paid for the stamps. One businessman used to leave large amounts of cash in his mailbox for Dad to take to the bank. Once, the amount came to $32,000.
A dozen years ago, when I traveled back to my hometown on the sad occasion of Dad's death, the mailboxes along the way reminded me of some of his stories. I thought I knew them all, but that wasn't the case.
As I drove home, I noticed two lamp poles, one on each side of the street. When my dad was around, those poles supported wooden boxes about four feet off the ground. One box was painted green, and the other was red, and each had a long narrow hole at the top with white lettering: SANTA CLAUS, NORTH POLE. For years children had dropped letters to Santa through those holes.
I made a turn at the corner and drove past the post office and across the railroad tracks to our house. Mom and I were sitting at the kitchen table when I heard footsteps. There, at the door, stood Frank Townsend, Dad's postmaster and great friend for many years. So we all sat down at the table and began to tell stories.
At one point Frank looked at me with tears in his eyes. “What are we going to do about the letters this Christmas？”he asked.
“The letters？”
“I guess you never knew.”
“Knew what？”
“Remember, when you were a kid and you used to put your letters to Santa in those green and red boxes on Main Street? It was your dad who answered all those letters every year.”
I just sat there with tears in my eyes. It wasn't hard for me to imagine Dad sitting at the old oak table in our basement reading those letters and answering each one. I have since spoken with several of the people who received Christmas letters during their childhood, and they told me how amazed they were that Santa had known so much about their homes and families.
For me, just knowing that story about my father was the gift of a lifetime.
1. It can be inferred from the passage that the writer regarded his travels with Dad as ________.
A. great chances to help other people
B. happy occasions to play with baby chickens
C. exciting experiences with a lot of fun
D. good opportunities to enjoy chocolate cookies

【要点综述】这是一篇感人的叙述亲情的文章，在这里，父亲是一个乡村送信人，这么多年来他都无私地为219个信箱服务，一直到他退休。但让作者没有料到的是，父亲还在每年圣诞节的时候扮演着圣诞老人的角色，默默地回复着孩子们写给圣诞老人的信。
1. C 推理判断题。从全文第一段提到的…always an adventure: There were animals to see…知，作者认为与父亲一起去乡下送信是一件惬意的事情，因为在路上碰到的事情令人激动不已，所以选C项。
. B 推理判断题。从文章第四段…One businessman used to leave…the amount came to $32,000.知，商人认为父亲是一个诚实且值得信赖的人，所以他才会这么相信他，让他把数目很多的钱送往银行，由此知B项为最佳答案。
. D 细节理解题。从文章最后几段可以看出，作者没有想到的是，父亲竟然还曾扮演过圣诞老人的角色，给孩子们回信，这大大出乎他的意料。这也可以从倒数第二段I just sat there with tears in my eyes.可以看出，我对父亲的这种行为感到非常吃惊和感动，由此选D项。
. C 文章结构题。从第四段知，作者在这里举到了几个事例，如帮人送鸡蛋，帮小姑娘支付邮票，甚至帮一个商人去存钱等等，这些都是例子，所以该段举了很多事例来说明父亲平凡中的“伟大”，故选C项。
59. D 推理判断题。从倒数第二段…and they told me how amazed they were that…推断知，当时小朋友们对于圣诞老人居然这么了解他们的家庭生活感到非常吃惊，所以答案选D项。
. A 主旨大意题。从全文知，本文作者主要讲述了自己的父亲，一个平凡中显现伟大的送信人的故事，所以用A项能较好地概括全文中心，这里用The Mail来突出父亲的工作和他的敬业，故A项最佳。
