A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components(元件), ”said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.

They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.

Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day-to-day basis.”

72. The difficulty the team of engineers met with while making the robotic fly was that ________.

A. they had no model in their mind

B. they did not have sufficient time

C. they had no ready-made components

D. they could no assemble the components

73. It can be inferred from paragraphs 3 and 4 that the robotic fly_________.

A. consists of a flight device and a control system

B. can just fly in limited areas at the present time

C. can collect information from many sources

D. has been put into wide application

74. Which of the following can be learned from the passage?

A. The robotic flyer is designed to learn about insects.

B. Animals are not allowed in biological experiments.

C. There used to be few ways to study how insects fly.

D. Wood’s design can replace animals in some experiments.

75. Which of the following might be the best title of the passage?

A. Father of Robotic Fly

B. Inspiration from Engineering Science

C. Robotic Fly Imitates Real Life Insect

D. Harvard Breaks Through in Insect Study

【語篇解讀】本文為一篇說明文,講述機器人蒼蠅的研發,面臨的困難以及前景。

段落

關鍵詞、句

大意推測

第一部分(Para. 1)

create the first robotic fly; the mechanical fly; a platform for a series of new high-tech systems;  what a fly does naturally; the size of a fat housefly; mini wings; perform controlled flight tasks.

哈佛大學的一組技師在自然界的激發下,創造了第一部機器人蒼蠅。進而描述了機器人蒼蠅的樣子與用途。

第二部分(Para. 2)

extremely important; as a whole system;  not just the sum of a bunch of individual components(元件); has been working on;for over a decade;got the go-ahead to start piecing together the components.;the added difficulty; off the shelf; have to develop them all on our own

機器人蒼蠅要的是一套完整的體系,而不是一組獨立原件簡單地相加。哈佛大學Robert Wood教授數十年都在致力于研究機器人蒼蠅這個課題。幾年前,他的團隊就開始了拼裝原件。但這個項目也遇到了困難:那些元件沒有一件能現貨供應的,只能自己做。

第三部分(Para. 3-4)

a series of systems to start and drive…;has a number of interdependencies on the individual components; was built into a set of power, computation, sensing and control systems; …the success of the project proves that…; these tiny components can be built and manufactured; is linked to; a small, off-board power source;  equip it with; a built-in power source; someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield; be able to take off, land and fly around.

從兩個方面說明機器人蒼蠅:一.機器人蒼蠅所需要的一套體系。看上去相當簡單地能夠移動翅膀的系統卻在那些單個原件中有很多相互依賴的成份,每個成分不僅要各自運轉良好,還要和與它相連的所有成分都配合好。二. 機器人蒼蠅配有內置電源,是為了將來有一天能在營救點,在牧場上或者戰場上從事數據收集工作。

第四部分(Para. 5)

a new way to study flight mechanics and control at insect-scale; …on board could have much broader applications; open scientific questions; difficult with the animals; using…instead; drives us on …

此設計為研究飛行力學和控制昆蟲規模提供了一種嶄新的方法。然而(搭載的)動力設備,傳感以及運算技術會有更廣泛的應用。Wood設計的機器人蒼蠅在某些動物實驗方面可以用來代替動物。

72. 答案:C.

解析:細節理解題。考生根據第二段最后一句 “The added difficulty with a project like this is that…可知事實上那些元件沒有一件能現貨供應的,要理解be off the shelf 的用法,所以選項C. they had no ready-made components就是對本句的同義替換,故為正確答案根據文章第一段Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly.是有制作模型的,故排除A。根據文章第二段“It’s extremely important for us to think about …, ”the Harvard engineering professor who has been working ….可知選項B. they did not have sufficient time他們沒有充足的時間,不合適;而選項D. they could no assemble the components他們不會組裝元件是對原文的誤解,并不是要組裝,故排除選項D。

73. 答案:B

解析:推理判斷題。題干要求在第三段和第四段來推測,所以根據文章內容but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. 故選項A. consists of a flight device and a control system是片面的,排除;根據第四段so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield.可知選項C.中的from many sources應為 from many sites/places,故排除;選項D. has been put into wide application的定位在第五段Yet, the power, sensing and computation technologies on board could have much broader applications.可知已經大量應用是錯誤的,故排除。縱觀三四兩段,尤其是第四段尾句“Basically it should be able to take off, land and fly around,” he said.可推斷出只有B. can just fly in limited areas at the present time正確。

74. 答案:D

解析:推理判斷題。文章末段的to study biology in ways…would be difficult with animals, but using these robots instead告訴我們這些機器人可以替代動物,故D項正確。考生注意的是,說明文末段尤其帶有轉折關系的路標詞往往是題眼所在。根據第四段so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. 可知A選項錯誤,故排除。文章最后一段中指出“You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said.,并沒有說:不允許拿動物進行生物實驗,故排除B選項。根據文章最后一段Wood says the design offers a new way to study flight mechanics and control at insect-scale.及“So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day-to-day basis.”可知以后會有更多的問題等待我們去探索,但并不是說過去在研究昆蟲飛行方面常常方法很少,故排除。

75. 答案:C

解析:主旨大意題。本題考查考生理解全文、提煉信息、概括總結的能力。選擇最佳標題,一般來說,考生只有通篇理解文章傳遞的信息,才可能概括出全文的最佳標題。對比四個選項,A選項意為“機器人蒼蠅之父”,文章的主題主要說明“機器人蒼蠅”,故排除。B選項“來自工程學中的靈感”與文章的主題“機器人蒼蠅”關系不大,故排除。D選項“哈福大學在昆蟲研究領域的突破”, 并沒有點明主題“機器人蒼蠅”,故排除。C選項既交待了“Robotic Fly” 又講了與真實生活中昆蟲的關系,所以爭取答案為C。

In many parts of the world, cars play an important role in daily life and many societies would not exist without them.  【小題1】 But this is the prediction made by a team of transport researchers who are taken seriously, not only by government but also by car manufacturers.
The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an international research program.  【小題2】 That will mean much saving, no accidents and better use of roads. The super-intelligent car in the future will drive itself.  【小題3】 Instead, we will have a choice of cars and change them as frequently as we change our clothing.
According to Dr. David Davis, who leads the research team, these predictions are based on the rising cost of the car culture, which had blocked up our cities, polluted our air, and caused more deaths than both world wars put together.
Davis says, cars will be fitted with some intelligent devices(裝置) to regulate(調節) the distance between one car and another.  【小題4】 computers are much safer drivers than people, so cars in a road train will be able to drive much closer together than cars driven by people.
By 2010, Dr. David Davis believes, car technology will give motorists a clear view of the road, whatever the weather conditions, by projecting an image of the road ahead on to the car’s windscreen.  【小題5】 Cars will be connected by an electronic tow bar to the car in front to form “road-trains”. “The front vehicle in such a train burns the normal amount.”says Davis. “but all the others in the train would burn about ten percent of the normal amount,  and so produce about ten percent of the pollution.”

A.The team there believes that by 2030 all cars will be computerized.
B.They believe that cars will become more important in 20 years.
C.And it will not be owned by one individual.
D.And by 2030, cars will travel in line, linked to each other electronically.
E.So the idea that in 20 years’ time, no one will own cars may be hard to believe.
F.Every driver will use less fuel in the car he owns.
G.The car will automatically speed up, or slow down, to match the speed of the car in front.

I shall never forget the day when the earthquake took place. The time was about 5 o’clock in the afternoon and I was driving along the road to take my daughter from school. Our plan was to go swimming together. I had finished my work at 4 o’clock and then gone to the Post Office. Then I’d stopped off at a shop in order to get some fresh fruit. We like to have some fruit to eat after our swim.

I was driving along a high road on my way to my daughter’s school. Over my road was another road which was built like a bridge for cars coming to the other way. I was hungry so I put the bag of apples in the seat beside me and started to eat one.

Suddenly I saw the cars in front of me start to move from side to side. Then my car started to shake! I didn’t know what was happening. Perhaps something had gone wrong with my car. I drove a little more slowly and then I stopped the car and at the same moment the road fell onto the cars in front of me.

I found myself in the dark. I couldn’t move. The bottom parts of both of my legs and my feet were hurting badly and I couldn’t move them. All around me was quiet. But above me I could hear shouts and a lot of noise. Then I memorized (記起) what had happened. I had been in an earthquake.

For about two hours nobody came. Luckily I could reach the bag of apples, so at least I had plenty to eat. Then I heard people climbing towards me. A team of people had come to see if anyone was under the broken road. I called out. “I’m here!” I heard a shout. Soon a stranger climbed to the side of the road near my car. “How are you doing?” he asked.

“Not too bad,” I said, “but my feet and leg feel as if they’re broken.” “We’ll have you out of there just as soon as we can.” They didn’t get me out until the next morning. I had been in my car for fourteen hours.

1.When the earthquake took place, the writer was ______.

A. on his way to the Post Office    B. stopping off a shop

C. doing some shopping          D. under a road built like a bridge

2.The writer’s car began to move from side to side because ________.

A. there was something wrong with his car

B. he ate apples as he drove

C. an earthquake began to happen

D. he drove too fast

3.Which is the following is TRUE according to the passage?

A. When the earthquake happened, the writer was with his daughter together.

B. The writer’s leg and feet were badly wounded in the earthquake.

C. The writer was saved as soon as the stranger climbed up the road.

D. The writer was frightened that he forgot everything that happened around.

Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.

Decibels(分貝) measured in water are different from those measured on land. A noise of 120 decibels on land causes pain to human ears. In water, a decible level of 195 would have the same effect.

Some scientists have suggested setting a noise limit of 120 decibles in oceans. They have observed that noises above that level can frighten and confuse whales.

A team of American and Canadian scientists discovered that loud noises could seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing, which seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected(感染的).

Many researches whose work depends on ocean sounds disagree with a limit of 120 decibels. They say such a limit would mean an end to important industrial and scientific research.

Scientists do not know how many and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they previously believed. They want to prevent noises from harming creatures in the ocean.

1.The second paragraph mainly tells us that the noises on land and in water       .

A.are both from human activities.

B.both do harm to sea animals

C.are measured differently

D.have the same effect on humans

2.As to(依據) the effects of noises on whales, which of the following statements is TRUE according to the passage?

A.They are deaf to noises.

B.Noises at a certain level may hurt them.

C.They are easily confused by noises.

D.Noises will limit their ability to reproduce.

3.Many researchers think that the noise limit of 120 decibels would        .

A.protect whales from noises

B.benefit them a lot in their research work

C.do good to their health

D.increase industrial output

4.What will scientists most probably do in the future?

A.Count the number of sea animals.

B.Stop their research on the ocean.

C.Study the effect of different noises.

D.Protect sea creatures from harmful noises.

Half of the world’s population is affected by Asian monsoons (季風), but monsoons are difficult to predict. American researchers have put together a 700-year record of the rainy seasons, which is expected to provide guidance for experts making weather predictions.

Every year, moist (潮濕的) air masses,known as monsoon,produce large amounts of rainfall in India, East Asia, Northern Australia and East Africa. All this wet air is pulled in by a high pressure area over the Indian Ocean and a low pressure area to the south.

According to Edward Cook, a weather expert at Columbia University in New York, the complex nature of the climate systems across Asia makes monsoons hard to predict. In addition, climate records for the area are too recent and not detailed enough to be of much use. Therefore, he and a team of researchers spent more than fifteen years traveling across Asia, looking for trees old enough to provide long-term records. They measured the rings(年輪), or circles, inside thousands of ancient trees in more than 300 places.

Rainfall has a direct link to the growth and width of rings on some kinds of trees. The researchers developed a document they are calling a Monsoon Asia Drought Atlas. It shows the effect of monsoons over seven centuries, beginning in the 1300s.

Professor Cook says the tree-ring records show periods of wet and dry weather. “If the monsoon basically fails or is a very weak one, the trees affected by monsoons at that location might put on a very narrow ring. But if the monsoon is very strong, the trees affected by that monsoon might put on a wide ring for that year. So, the wide and narrow ring widths of the chronology(大事年表) that we developed in Asia provide us with a measure of monsoon variability.” With all this information, researchers say they can begin to improve computer climate models for predicting the behavior of monsoons.

“There has been widespread famine and starvation and human dying in the past in large droughts. And on the other hand, if the monsoon is particularly heavy, it can cause extensive flooding.” said Eugene Wahl, a scientist with America’s National Oceanic and Atmospheric Administration. “So, to get a sense of what the regional moisture patterns have been, dryness and wetness over such a long period of time in great detail, I would call it a kind of victory for climate science.”

1.What’s the passage mainly about?

A.The effects of Asian monsoons.             B.The necessity of weather forecast.

C.The achievements of Edward cook.          D.A breakthrough in monsoon prediction.

2.It is difficult for experts to predict Asian monsoons because _______.

A.it is hard to keep long-term climate records.

B.they are formed under complex climate systems.

C.they influence many nations.

D.there is heavy rainfall in Asia.

3.What can be inferred from the passage?

A.Long and detailed climate records can offer useful information for monsoon research.

B.The Monsoon Asia Drought Atlas has a monsoon record for about 1,300 years.

C.The trees affected by monsoon grow fast if the monsoon is weak.

D.The rainfall might be low although the monsoon is strong in monsoon-affected areas.

4.According to Professor Cook, the rings of the trees _______.

A.determine the regional climate.

B.have a great influence on the regional climate.

C.offer people information about the regional climate.

D.reflect all kinds of regional climate information.

5.What do we know about the research according to Eugene Wahl?

A.It is a great achievement in climate science.

B.It should include information about human life in the past.

C.It has analysed moisture models world wide,

D.It will help people prevent droughts and floods.

6.Which of the following best describes the tone of this passage?

A.Matter-of –fact    B.Pessimistic         C.Humorous         D.Friendly.
