　　2017年英語六級閱讀理解練習題及答案(一)

　　Scattered around the globe are more than 100 small regions of isolated volcanic activity known to geologists as hot spots. Unlike most of the world's volcanoes. they are not always found at the boundaries of the great drifting plates that make up the earth's surface; on the contrary, many of chem lie deep in the interior of a plate. Most of the hot spots move only slowly, and in some cases the movement of the plates past them has left trails of dead volcanoes. The bot spots and their volcanic trails are milestones that mark the passage of the plates.

　　That the plates are moving is now beyond dispute. Africa and South America. for example. are moving away from each other as new material is injected into the sea floor between them. The complementary coastlines and certain geological features that seem to span the ocean are reminders of where the two continents were once joined. The relative motion of the plates carrying these continents has been constructed in detail, but the motion of one plate with respect to another cannot readily be translated into motion with respect to the earth’s interior. It is not possible to determine whether both continents are moving in opposite directions or whether one continent is stationary and the other is drifting away from it. Hot spots. anchored in the deeper layers of the earth, provide the measuring instruments needed to resolve the question. From an analysis of the hot-spot population it appears that the African plate is stationary and that it has not moved during the past 30 million years.

　　The significance of hot spots is not confined lo their role as a frame of reference. It now appears that they also have an important influence on the geophysical processes chat propel the plates across the globe. When a continental plate comes to rest over a hot spot. the material rising from deeper layer creates a broad dome. As the dome grows, it develops deep fissures (cracks); in at least a few cases the continent may break entirely along some of these fissures, so that the hoc spot initiates the formation of a new ocean. Thus just as earlier theories have explained the mobility of the continents, so hot spots may explain their mutability (inconstancy).

　　1.We can learn from che first paragraph that_____________.

　　A. there are no volcanic activities on hoc spots

　　B. most hoc spots are located in the inner part of a plate

　　C. hot spots usually lie. at che boundaries of drifting plates;

　　D. the passage of plates through hot spots will leave dead volcanoes

　　2.The author believes that_____________.

　　A) the motion of the plates corresponds to thar of the earth's interior

　　B) the geological theory about drifting plates has been proved to be true

　　C) the hot spots and the plates move slowly in opposite directions

　　D) the movement of hot spots proves the continents are moving apart

　　3.That Africa and South America were once joined can be deduced from the fact that_________.

　　A) the two continents are still moving in opposite directions

　　B) they have been found to share certain geological features

　　C) the African plate has been stable for 30 million years

　　D) over 100 hot spots are scattered all around the globe

　　4.The hot spot theory may prove useful in explaining__________.

　　A) the structure of the African plates.

　　B) the revival of dead volcanoes.

　　C) the mobility of the continents.

　　D) the formation of new oceans.

　　5.The passage is mainly about______________.

　　A) the features of volcanic activities

　　B) the importance of the theory about drifting plates

　　C) the significance of hot spots in geophysical studies

　　D) the process of the formation of volcanoes

　　1.從文章第一段我們可以知道，_____________。

　　A)在熱點沒有火山活動

　　B)大多數的熱點位于板塊內部

　　C)熱點通常位于漂移板塊的邊界處

　　D)板塊經過熱點后會留下死火山

　　[B]根據題干直接查找到第1段。第2句第2個分句提到“其中很多位于板塊內部的深處”，而表達同樣含義的是B選項。該段第1句指出，這些互不相連、發生火山運動的小地區，地質學家稱之為熱點，可見A項錯誤。選項C與第2句第1個分句的內容相反。倒數第2句提到“在某些情形下，板塊移動經過熱點留下死火山的痕跡”，即不是所有板塊移動都會留下死火山的痕跡，故D錯。

　　2.作者相信______________。

　　A)板塊運動與地球內部是一致的

　　B)若干漂移板塊的`地質學理論被證明是正確的

　　C)熱點與板塊向相反方向緩慢移動

　　D)熱點的移動證明了大陸在相互遠離

　　[B]文章第2段的開頭指出That the plates are moving is now beyond dispute。beyond dispute意為“毋庸置疑”，故答案選B項。從第2段第4句的“但是一個板塊相對于另外一個板塊的運動不能被順理成章地解釋成板塊與它相對于地球內部的運動”，可排除A項。

　　3.可以從_________________的事實，推斷非洲和南美洲曾經是連接在一起的。

　　A)兩個洲仍然向相反方向移動

　　B)人們發現兩個洲擁有某些共同的地質特征

　　B)非洲板塊3千萬年來一直保持穩定

　　D)超過100個熱點散步在全球

　　[B]從第2段的第3句可知，非洲和南美洲曾經連接在一起的證據有兩個——海岸線所具有的互補的特征(complementary coastlines)及某些地質特點(certain geological features)。B項符合后者，故為正確答案。

　　4.熱點理論可能在解釋___________時被證明是有用的。

　　A)非洲板塊的結構

　　B)死火山的復活

　　C)大洲的可動性

　　D)新海洋的形戒

　　[D]關于hot spot theory的作用，除了第2段提到的參照作用外，第3段論及的另一個重要作用在于它能夠推動扳塊在地球表面漂移(propel the plates across the globe)，從而引發了新海洋的形成(initiates the formation of a new ocean)。故答案選D項。

　　5.文章主要是關于_______________。

　　A)火山活動的特征

　　B)漂移板塊理論的重要性

　　C)熱點在地理物理學研究中的意義

　　D)火山形成的過程

　　[C]全文三個段落主要是圍繞“熱點對于地球物理學研究的意義”而展開的。故答案選C項。全篇共三段，第l段講的是hot spots的定義與分布，第2段講hot spots在大陸板塊移動中的參照作用，第3段講hot spots引起新海洋形成的地球物理意義。

　　2017年英語六級閱讀理解練習題及答案(二)

　　“The world's environment is surprisingly healthy. Discuss.”If that were an examination topic, most students would tear it apart. offering a long list of complaints: from local smog (煙霧) to global climate change, from the felling(砍伐) of forests to the extinction of species. The list would largely be accurate,the concern legitimate. Yet the students who should be given the highest marks would actually be those who agreed with the statement. The surprise is how good things are, not how bad.

　　After all. the world's population has more than tripled during this century, and world output has risen hugely. so you would expect the earth itself to have been affected. Indeed, if people lived, consumed and produced things in the same way as they did in 1900 (or 1950. or indeed 1980), the world by now would be a pretty disgusting place: smelly, dirty. toxic and dangerous.

　　But they don't. The reasons why they don't. and why the environment has not been ruined. have to do with prices. technological innovation, social change and government regulation in response to popular pressure. That is why today's environmental problems in the poor countries ought. in principle, to be solvable.

　　Raw materials have not run out. and show no sign of doing so. Logically. one day they must: the planet is a finite place. Yet it is also very big. and man is very ingenious. What has happened is chat every time a material seems to be running short, the price has risen and. in response. people have looked for new sources of supply, tried to find ways to use less of the material, or looked for a new substitute. For this reason prices for energy and for minerals have fallen in real terms during the century. The same is true for food. Prices fluctuate, in response to harvests. natural disasters and political instability; and when they rise, it takes some time before new sources of supply become available. But they always do. assisted by new farming and crop technology. The long-term trend has been downwards.

　　It is where prices and markets do not operate properly that this benign (良性的) trend begins to scumble, and the genuine problems arise. Markets cannot always keep the environment healthy. If no one owns the resource concerned. no one has an interest in conserving it or fostering it: fish is the best example of this.

　　◆1.According to the author, most students_________________.

　　A) believe the world's environment is in an undesirable condition

　　B) agree that the environment of the world is not as bad as it is thought to be

　　C) get high marks for their good knowledge of the world's environment

　　D) appear somewhat unconcerned about the state of the world's environment

　　◆2.The huge increase in world production and population________________.

　　A) has made the world a worse place to live in

　　B) has had a positive influence on che environment

　　C) has not significantly affected the environment

　　D) has made the world a dangerous place to live in

　　◆3.One of the reasons why the long-term trend of prices bas been downwards is that__________.

　　A) technological innovation can promote social stability

　　B) political instability will cause consumption io drop

　　C) new farming and crop technology can lead to overproduction

　　D) new sources are always becoming available

　　◆4.Fish resources are diminishing because_________________.

　　A) no new substitutes can be found in large quantities

　　B) they are not owned by any particular entity

　　C) improper methods of fishing have ruined che fishing grounds

　　D) water pollution is extremely serious

　　◆5.The primary solution to environmental problems is_______________.

　　A) to allow market forces to operate properly

　　B) to curb consumption of natural resources

　　C) to limit the growth of the world population

　　D) to avoid fluctuations in prices

　　◆1.作者認為，大部分學生__________________。

　　A)相信全球環境現在是糟糕的

　　B)同意全球環境沒有人們想象的那么糟糕

　　C)在關于全球環境知識上掌握得很好，取得了很高的分數

　　D)對全球環境表現出不關心的態度

　　[A]根據文章第1段前兩句“如果以《全球環境狀況非常好》作為考試題，大多數學生會將試卷撕碎，并列出一大堆的抱怨，從煙霧到全球氣候變暖，從砍伐森林到物種滅絕”，由此可推斷，大多數學生認為全球環境并不令人滿意。因此,A正確。

　　◆2.世界生產力和人口的激增，_________________。

　　A)使得這個世界的居住環境更加糟糕

　　B)已經對環境造成了正面的影響

　　C)并沒有嚴重地影響環境

　　D)使得世界的居住環境更加危險

　　[C]根據文章第2段全段和第3段首句“本世紀，全球人口增加了三倍多，全球產量也有巨大的增長，因此你可能會認為地球會受到影響。的確.如果人們還像1900年或1950年甚至1980年那樣居住，消費和生產，那么到現在，地球很可能是一個令人厭惡的地方但人們沒有這樣做”，注意此處的虛擬語氣，由此可推斷產量和人口的增加并沒有對全球環境造成太大的影響，故此，應選C。

　　◆3.從長期來看，價格是下降的，其中的一個原因是_____________。

　　A)技術創新促進了社會穩定型

　　B)政治的不穩定性會導致消費下降

　　C)新的農耕和作物技術會導致過度生產

　　D)總能獲得新的資源

　　[D]根據文章第4段第4、5句“每次當一種資源似乎就要匱乏時，價格就會上升，相應地，人們會尋找新的`資源，想方設法找到節省資源的方法或者尋找新的替代品。正因為如此，本世紀能源和礦產品的價格實質上已經下降了一，故應選D。

　　◆4.魚類資源在減少，因為___________________。

　　A)沒有大量的新替代品

　　B)魚類資源不屬于任何一個實體

　　C)不當的捕魚方法損壞了漁區

　　D)水質污染非常嚴重

　　[B]根據文章最后一段第2、3句“市場并不能總是保持環境的健康發展。如果相關的資源不屬于任何人，人們就沒有興趣保護它、培養它。魚類資源就是一個最好的例子”，因此，可推斷B正是魚類減少的原因。

　　◆5.解決環境問題的主要辦法是_________________。

　　A)讓市場力量恰當地運作

　　B)減步自然資源的消耗

　　C)限制世界人口增長

　　D)避免價格波動

　　[A]根據文章展后一段第1句“在價格和市場手段不能正常運轉的地方，這種良性的趨勢就會動搖，就會出現環境能源等問題”，故此，讓市場價格手段正常地發揮作用才是解決環境問題的方法，A與文章的意思相符，故而正確。

　　2017年英語六級閱讀理解練習題及答案(三)

　　In the last two hundred years there have been great changes in the method of production of goods. This is now also true of the building industry; for mechanization has been introduced. System building can save both time and money. The principle of system building is that the building is made from a set of standard units. These are either made at the building-site or at a factory. Some designers, in fact, are standardizing the dimensions of rooms. They are made in multiples of a single fixed length, usually ten centimeters. This is called a modular (標準件的) system, and it means that manufactures can produce standardized fittings at a lower cost. The most important fact about system building is its speed. A ten-storey flat, for example, can be completed in four months.

　　There are several new methods of system building. One is the panel method. In this case, the construction company sometimes erects a factory on the site. The walls and floors of the building, called panels, are cast in a horizontal or vertical position. Conduits for electrical wires and sleeves for pipes are cast in the panels when they are being made. The moulds for making these castings are situated all around the building.

　　After the concrete panels are cast, they are allowed to set and harden for a week. Next they are lifted by a tower crane on to any section of the building. There the panels are cemented together at their joints and the floor covering is laid.

　　After the panels have been cemented together, the crane lifts a case into the area. It contains all the fittings to be installed, such as wash-basins, radiators and pipes. Finishing tradesmen, such as plumbers, plasterers, painters and electricians, follow behind to complete the work.

　　In some building developments, in some countries, whole flats with internal features like their bathrooms, bedrooms and connecting stairs, and weighing as much as twenty tons, are carried to the building-site ready-made. A giant overhead crane is used to lift them into position. In the future, this method may become more widespread.

　　◆1. The main difference between panel method and the method discussed in the last paragraph is_______.

　　A. the latter uses ready-made internal features

　　B. panels are cast in a level position

　　C. the former is used to build walls and floors while the latter to construct bathrooms or bedrooms

　　D. the former is more expensive than the latter

　　◆2. Which of these statements is TRUE of system building?

　　A. It employs more men. B. It is difficult and dangerous.

　　C. It can save both time and money. D. It means less mechanization.

　　◆3. According to the passage, the principle of system building is that_______.

　　A. construction methods are safer

　　B. buildings are made from a set of standardized units

　　C. similar buildings can be produced
