Read the passage and mark the letter A, B, C or D to answer the following questions.

Most sources of illumination generate light over an appreciable period, and indeed if an object is lit for a very brief time (1ess that 1/25 second), the human eye will not react in time to see the object. A photographic emulsion - that is, a light-sensitive coating on photographic film, paper, or glass - will, however, record much shorter bursts of light. A photographic flash can therefore be used to capture high-speed movement on film as well as to correct deficiencies of the normal surrounding lighting. Photoflash is now generated electronically, but the earliest form, first used in 1864, was a paper bag containing

magnesium wire and some oxygen-rich substance, such as potassium chlorate. When the bag was ignited, the metal burned with an intense flash. A contemporary observer reported that "this quite unsafe device seems to have done nothing worse that engulf the room in dense smoke and lead to pictures of dubious quality and odd poses.”

The evolution of the photoflash was slow, flashbulbs, containing fine wire made of a metal, such as magnesium or aluminum, capable of being ignited in an atmosphere of pure oxygen at low pressure, were introduced only in the 1920's. In the earliest type, the metal was separated from the oxygen by a thin glass bulb. The flash was fired by piercing the bulb and allowing the oxygen to come into contact with the metal, which ignited spontaneously. Later bulbs were fired by an electric battery, which heated the wire by passing a small current through it. Other combinations, such as the pairing of oxygen difluoride with zirconium, have also been used. In each case enough energy is given out to heat the oxidizable metal momentarily to a white hot emission of visible light. The smoke particles are so small that they cool rapidly; but since they are white, they contribute to the brilliance by reflecting the light from their still glowing neighbors. A slightly bigger form of the metal will burn for a longer time.

Which of the following most accurately reflects the main idea of the last paragraph? 

A. The time when photoflash was first used. 

B. How metal burns in an atmosphere of pure oxygen. 

C. How early photoflash worked. 

D. The role of glass in flashbulb.

Read the following passage and mark the letter A, B,c or D on your answer sheet to indicate the correct answer to each of the questions.

Coca Cola is a popular drink for people all over the world. At first, very few people drank Coca Cola, but now it is sold in more than 160 countries. More than 1.6 billion gallons are sold every year.

Coca Cola was invented by Dr. John Pemberton in Atlanta on 8 May, 1886. However, the name Coca Cola was given by Frank Robinson, one of Dr. Pemberton’s partners. Later, in 1888, the business was sold to another man, Asa Candler. He opened his first factory to produce this drink in 1895 in Dallas, Texas. Since then, a great quantity of Coca Cola has been produced there.

Since 1982, a special kind of Coca Cola has been made for overweight people - diet Coke. They have used many clever advertisements to increase the amount of Coca Cola sold every year.

Besides Coca Cola, there are many other drinks of the same kind sold all over the world such as Pepsi Cola, Sp - Cola and Dr. Pepper. However, Coca Cola is the most popular. People drink Coca Cola with their meals, when they are thirsty or when they socialize with friends.

It is certain that more and more people will drink Coca Cola all over the world in this century.

28.       The first Coca Cola factory was opened in Dallas by______.

A. Dr. Pemberton                                  B. Asa Candler

C. Frank Robinson                                D. Dr. Pepper

29.       The word “there” refers to______.

A. where Coca Cola was first made B. the city with the first Coca Cola factory

C. Atlanta, a U.S. City                          D. the place that Coca Cola is sold

30.       Diet Coke is used for ______people.

A. fat                     B. sick                     C. thin                    D. small

31.       Which of the following is closest in meaning to the word “popular”?
