The first two decades of this century were dominated by the microbe hunters. These hunters had tracked down one after another of the microbes responsible for the most dreaded scourges of many centuries: tuberculosis, cholera, diphtheria. But there remained some terrible diseases for which no microbe could be incriminated: scurvy, pellagra, rickets, beriberi. Then it was discovered that these diseases were caused by the lack of vitamins, a trace substance in the diet. The diseases could be prevented or cured by consuming foods that contained the vitamins. And so in the decades of the 1920's and 1930's, nutrition became a science and the vitamin hunters replaced the microbe hunters.
In the 1940's and 1950's, biochemists strived to learn why each of the vitamins was essential for health. They discovered that key enzymes in metabolism depend on one or another of the vitamins as coenzymes to perform the chemistry that provides cells with energy for growth and function. Now, these enzyme hunters occupied center stage.
How do vitamins influence health?
A. They are broken down by cells to produce energy.
B. They are necessary for some enzymes to function.
C. They protect the body from microbes
D. They keep food from spoiling.

According to airline industry statistics, almost 90 percent of airline accidents are survivable or partially survivable. But passengers can increase their chances of survival by learning and following certain tips. Experts say that you should read and listen to safety instructions before takeoff and ask questions if you have uncertainties. You should fasten your seat-belt low on your hips and as tightly as possible. Of course, you should also know how the release mechanism of your belt operates. During takeoffs and landings, you are advised to keep your feet flat on the floor. Before takeoff you should locate the nearest exit and an alterative exit and count the rows of seats between you and the exits so that you can find them in the dark if necessary.
In the event that you are forewarned of a possible accident, you should put your hands on your ankles and keep your head down until the plane comes to a complete stop. If smoke is present in the cabin, you should keep your head low and cover your face with napkins, towels, or clothing. If possible, wet these for added protection against smoke inhalation. To evacuate as quickly as possible, follow crew commands and do not take personal belongings with you. Do not jump on escape slides before they are fully inflated, and when you jump, do so with your arms and legs extended in front of you. When you get to the ground, you should move away from the plane as quickly as possible, and never smoke near the wreckage.
What is the main topic of the passage?
A. Guidelines for increasing aircraft passenger survival
B. Procedures for evacuating aircraft
C. Safety instructions in air travel
D. Airline industry accident statistics

One crucial development in this movement toward industrialization was the growth of the railroads. The railway network expanded rapidly until the railroad map of the looked like a spider's web, with the steel filaments connecting all important sources of raw materials, their places of manufacture, and their centers of distribution. The railroads contributed to the industrial growth not only by connecting these major centers, but also by themselves consuming enormous amounts of fuel, iron, and coal.
Many factors influenced emerging modes of production. For example, machine tools, the tools used to make goods, were steadily improved in the latter part of the nineteenth century-always with an eye to speedier production and lower unit costs. The products of the factories were rapidly absorbed by the growing cities that sheltered the workers and the distributors. The increased urban population was nourished by the increased farm production that, in turn, was made more productive by the use of the new farm machinery. American agricultural production kept up with the urban demand and still had surpluses for sale to the industrial centers of .
The labor that ran the factories and built the railways was recruited in part from American farm areas where people were being displaced by farm machinery, in part from Asia, and in part from . now began to send tides of immigrants from eastern and southern Europe-most of whom were originally poor farmers but who settled in American industrial cities. The money to finance this tremendous expansion of the American economy still came from European financiers for the most part, but the Americans were approaching the day when their expansion could be financed in their own "money market."
According to the passage, who were the biggest consumers of manufactured products?
A. City dwellers
B. Farmers
C. Railway workers
D. Europeans

Western people rely on technical and mechanical solutions in everything they do. Refrigerators preserve their food, washing machines clean their underwear and computers are supposed to solve all their problems. When they are ill, they rely on the surgeon’s knife. If their hearts are running down, then they must be repaired, if they cannot be repaired, they should be replaced, just as an old car sometimes gets a new engine. But up to now we have had a shortage of donors to give their hearts, to keep one person alive, another donor had to die.
Nowadays there is more and more talk about using monkeys. Every monkey has a near-human heart, and humans have always been over careful in respecting the lives and well-being of other animals. This includes the life and well-being of other humans. Therefore, in the early years of the 22nd century - It was told the mass killings of monkeys may occur. We’ll need to use their hearts for human consumption.
Monkeys, on the whole, are happier creatures than their near relatives, Homo sapiens, or man. They know fear, of course, and they face real dangers, but they are also more intelligent than us. They create no unnecessary dangers for themselves, they run no businesses, chase no money, are unimpressed by gold – that utterly useless metal, and they do not care at all about hell or evil spirits. I have a vague feeling that it is not monkeys’ hearts that we ought to implant in ourselves, but monkeys’ brains.
The author says that monkeys….
A. people will careless about other human beings
B. Monkeys will become extinct
C. Monkey hearts will be used in transplant operations
D. Monkey hearts will form part of our diet

One of the most renowned Spanish architects of all time was Antoni Gaudi. Gaudi's emergence as one of 's preeminent artists at the end of the nineteenth century marked a milestone in the art world.
Gaudi's popularity helped to bring about the acceptance and rebirth of the Catalan language, which had been banned during the literature and art. Gaudi shares his Catalonian background with two other famous Spanish artists, Pablo Picasso and Miro. The diverse ethnic background of the region greatly influenced the work of Picasso and Miro, as well as Gaudi. Thus, their works were a combination of an old history and an active, vivid imaginary world. This has sometimes been referred to as the “Catalan Mind.” Yet it was perhaps Gaudi who had the greatest talent for bringing together diverse groups, ones which others viewed as being too diametrically opposed to be capable of coming together and co-existing amicably.
This was apparent not only in the artists and other individuals who surrounded him, but also in the varied styles and techniques he employed in his architecture. Much of his work can be seen in , where his structures are known as a fine representation of modernism. He also used a great variety of color in his buildings, and this art nouveau is often associated with his own unique style of design. All of these factors are what helped put him at the forefront of art movements to come: his unique ability to take on and transform traditional Spanish elements with the emerging diverse ethnic groups, merging these with his own fertile imagination, and consequently turning these forces into some of the greatest architecture the world has ever seen.
Miro has been viewed as being a prototype of
A. Spanish architecture
B. the Catalan mind
C. a fantasy
D. the Castilian mind

An example of a bizarre occurrence regarding a species of frog dates from the summer of 1995, when 'an explosion' of multi-coloured frogs of the species Rana klepton esculenta occurred in the Netherlands. Normally these frogs are brown and greenish-brown, but some unknown contributory factor is turning these frogs yellow and/or orange. Nonetheless, so far, the unusual bi- and even tri-coloured frogs are functioning similarly to their normal-skinned contemporaries. It is thought that frogs with lighter coloured skins might be more likely to survive in an increasingly warm climate due to global warming.
Highly-coloured frogs are an unusual phenomenon in nature.
