　　雅思閱讀試題及答案 1

　　Almost everyone with or without a computer is aware of the latest technological revolution destined to change forever the way in which humans communicate， namely， the Information Superhighway， best exemplified by the ubiquitous Internet. Already， millions of people around the world are linked by computer simply by having a modem and an address on the `Net， in much the same way that owning a telephone links us to almost anyone who pays a phone bill. In fact， since the computer connections are made via the phone line， the Internet can be envisaged as a network of visual telephone links. It remains to seen in which direction the Information Superhighway is headed， but many believeit is the educational hope of the future.

　　The World Wide Web， an enormous collection of Internet addresses or sites， all of which can be accessed for information， has been mainly responsible for the increase in interest in the Internet in the 1990s. Before the World Wide Web， the `Net was comparable to an integrated collection of computerized typewriters， but the introduction of the `Web in 1990 allowed not only text links to be made but also graphs， images and even video.

　　A Web site consists of a `home page， the first screen of a particular site on the computer to which you are connected， from where access can be had to other subject related `pages(or screens) at the site and on thousands of other computers all over the world. This is achieved by a process called `hypertext. By clicking with a mouse device on various parts of the screen， a person connected to the `Net can go traveling， or surfing through a of the screen， a person connected to the `Net can go traveling， or `surfing through a web of pages to locate whatever information is required.

　　Anyone can set up a site; promoting your club， your institution， your companys products or simply yourself， is what the Web and the Internet is all about. And what is more， information on the Internet is not owned or controlled by any one organization. It is， perhaps， true to say that no one and therefore everyone owns the `Net. Because of the relative freedom of access to information， the Internet has often been criticised by the media as a potentially hazardous tool in the hands of young computer users. This perception has proved to be largely false however， and the vast majority of users both young and old get connected with the Internet for the dual purposes for which it was intended - discovery and delight.

　　TRUE/FALSE/NOT GIVEN

　　1.Everyone is aware of the Information Superhighway.

　　2.Using the Internet costs the owner of a telephone extra money.3.Internet computer connections are made by using telephone lines.

　　Reading Passage 1: Toughened Glass - A Flawed Innovation

　　Toughened glass, also known as tempered glass, has become a staple in modern architecture due to its superior strength compared to ordinary glass. The manufacturing process involves heating ordinary glass to approximately 620°C followed by rapid cooling, creating a material that is up to five times stronger. When it breaks, it shatters into small, blunt fragments rather than sharp shards, reducing the risk of injury. These properties have made it the preferred choice for applications ranging from skyscraper windows to smartphone screens.

　　However, toughened glass has a little-known vulnerability: spontaneous shattering. In rare cases, the glass can break without any apparent external force. This phenomenon has plagued architects and engineers for decades, with incidents reported in public buildings, homes, and even vehicles. A 2018 study by the Glass and Glazing Federation found that approximately 1 in 30,000 toughened glass panels will shatter spontaneously.

　　The root cause lies in the manufacturing process. During production, tiny impurities called nickel sulfide inclusions can form within the glass. These inclusions are harmless at high temperatures but undergo a phase transformation as the glass cools. Over time, this transformation causes the inclusions to expand, creating internal stress. When the stress exceeds the glasss tolerance—often years after installation—the panel shatters suddenly.

　　Environmental factors can accelerate this process. Temperature fluctuations are a key trigger, as repeated heating and cooling exacerbate the expansion of nickel sulfide inclusions. Humidity and UV radiation may also play a role, though their exact impact is still being researched. In one well-documented case, a toughened glass door in a shopping mall shattered on a hot summer day after direct sunlight heated the panel for several hours.

　　To address this issue, manufacturers have developed quality control measures. Advanced X-ray technology can detect nickel sulfide inclusions before the glass leaves the factory, reducing the risk of defective panels reaching the market. Some producers also use a process called "heat soaking," which involves heating toughened glass to 290°C for several hours. This accelerates the phase transformation of nickel sulfide, causing any flawed panels to shatter during production rather than after installation.

　　Despite these improvements, spontaneous shattering remains a concern. Architects are now advised to use laminated toughened glass for critical applications. This combines a layer of toughened glass with a polyvinyl butyral interlayer, which holds the fragments together if shattering occurs, preventing injury and property damage. As research continues, scientists hope to develop entirely new glass compositions that eliminate nickel sulfide inclusions altogether.

　　Questions 1-5: True/False/Not Given

　　Reading Passage 2: The History of Twin Studies

　　The scientific study of twins has long been a valuable tool for understanding the interplay between genetics and environment. Twin research dates back to the 19th century, when Francis Galton—a cousin of Charles Darwin—first recognized the potential of twins to illuminate the nature-nurture debate. Galton’s 1875 paper "The History of Twins" laid the groundwork for modern twin studies, arguing that similarities between identical twins indicated genetic influence.

　　Twins are categorized into two types: monozygotic (MZ) and dizygotic (DZ). Monozygotic twins develop from a single fertilized egg that splits into two embryos, resulting in individuals with nearly identical DNA. Dizygotic twins form from two separate eggs fertilized by different sperm, sharing approximately 50% of their genes—similar to ordinary siblings. This distinction is crucial for research, as comparing the two types allows scientists to isolate genetic and environmental factors.

　　The first large-scale twin study was conducted in 1924 by Hermann Siemens in Germany. Siemens analyzed data from 1,000 twin pairs, focusing on the inheritance of physical traits such as eye color and height. His findings confirmed Galton’s hypothesis that genetic factors play a significant role in determining physical characteristics. However, Siemens also noted that environmental factors, such as nutrition, could modify these traits.

　　In the mid-20th century, twin studies expanded to include psychological traits. A landmark 1956 study by Leonard Heston examined the heritability of schizophrenia using twin pairs where one sibling had the disorder. Heston found that identical twins of schizophrenic individuals had a 46% chance of developing the condition, compared to only 14% for dizygotic twins. This provided strong evidence for a genetic component in schizophrenia.

　　The 1970s saw the rise of adoption studies, which combined twin research with adoption data. These studies compared identical twins separated at birth and raised in different environments (adoption twins) with those raised together. One famous example is the Minnesota Twin Study, which began in 1979 and followed 137 twin pairs over several decades. The study found striking similarities between separated identical twins in areas such as personality, intelligence, and even hobbies—suggesting a strong genetic influence on these traits.

　　Critics of twin studies argue that they oversimplify the nature-nurture interaction. They point out that identical twins may receive more similar treatment than dizygotic twins, a phenomenon known as "equal environment bias." Additionally, adoption studies have limitations, as adoption agencies often place twins in similar socioeconomic environments. Modern researchers address these issues by using more sophisticated statistical models to account for environmental similarities.

　　Today, twin studies continue to advance our understanding of genetics and environment. With the advent of genomic sequencing, researchers can now link specific genes to traits identified in twin studies. This integration of classical twin research with modern genetics has opened new avenues for personalized medicine, allowing scientists to predict disease risk based on genetic profiles. As technology progresses, twin studies remain a cornerstone of genetic research.

　　Reading Passage 3: The Future of Urban Farming

　　Urban farming—the practice of cultivating food in cities—has emerged as a potential solution to the challenges of food security and sustainability in the 21st century. With the global population projected to reach 9.7 billion by 2050, and 68% of people living in urban areas, traditional agricultural systems face increasing pressure to meet demand. Urban farming offers a way to produce food closer to consumers, reducing transportation costs and carbon emissions.

　　One of the most innovative forms of urban farming is vertical farming, which involves growing crops in stacked layers or vertically inclined surfaces. This method maximizes space efficiency, allowing production in areas where land is scarce. Vertical farms use hydroponic or aeroponic systems, which grow plants without soil—instead delivering water and nutrients directly to the roots. These systems use up to 95% less water than traditional agriculture, a critical advantage in regions facing water scarcity.

　　Another promising approach is rooftop farming. Rooftops, which are often underutilized in cities, can be transformed into productive gardens. Rooftop farms not only produce food but also provide environmental benefits: they reduce urban heat island effect by absorbing sunlight that would otherwise be reflected by concrete, and improve air quality by filtering pollutants. In New York City, the Brooklyn Grange operates two rooftop farms covering over 65,000 square feet, producing 50,000 pounds of vegetables annually and employing local residents.

　　Community gardens are a more traditional form of urban farming that fosters social connections while producing food. These gardens are typically managed by local residents who share plots and harvests. Research has shown that community gardens improve food access in low-income neighborhoods, where fresh produce is often scarce (a problem known as "food deserts"). They also promote mental health by providing green space and opportunities for physical activity.

　　Despite its benefits, urban farming faces several challenges. High startup costs are a major barrier, especially for vertical farms that require specialized equipment. Limited access to land and zoning restrictions also hinder expansion—many cities have regulations that prohibit commercial farming in residential areas. Additionally, urban farmers must address soil contamination in older cities, where land may contain heavy metals or pollutants from industrial activity.

　　Technological advancements are helping to overcome these obstacles. Sensor technology allows farmers to monitor plant health and optimize water and nutrient delivery, increasing yields and reducing waste. Renewable energy sources such as solar panels can power vertical farms, making them more sustainable and cost-effective. Some cities are also revising zoning laws to support urban farming—for example, Chicago’s Urban Agriculture Zoning Ordinance allows commercial farming in certain residential areas and provides tax incentives for farmers.

　　The future of urban farming looks promising as more cities embrace the concept. A 2023 report by the Food and Agriculture Organization (FAO) estimates that urban farming could supply 15-20% of global food demand by 2050. This would not only enhance food security but also create jobs, reduce environmental impact, and build more resilient communities. As technology improves and policies adapt, urban farming may become an integral part of future urban landscapes.
