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
For centuries, time was measured by the position of the sun with the use of sundials. Noon was recognized when the sun was the highest in the sky, and cities would set their clock by this apparent solar time, even though some cities would often be on a slightly different time. Daylight Saving Time (DST), sometimes called summer time, was instituted to make better use of daylight. Thus, clocks are set forward one hour in the spring to move an hour of daylight from the morning to the evening and then set back one hour in the fall to return to normal daylight.
Benjamin Franklin first conceived the idea of daylight saving during his tenure as an American delegate in Paris in 1984 and wrote about it extensively in his essay, "An Economical Project." It is said that Franklin awoke early one morning and was surprised to see the sunlight at such an hour. Always the economist, Franklin believed the practice of moving the time could save on the use of candlelight, as candles were expensive at the time.
In England, builder William Willett (1857–1915) became a strong supporter for Daylight Saving Time upon noticing blinds of many houses were closed on an early sunny morning. Willet believed everyone, including himself, would appreciate longer hours of light in the evenings. In 1909, Sir Robert Pearce introduced a bill in the House of Commons to make it obligatory to adjust the clocks. A bill was drafted and introduced into Parliament several times but met with great opposition, mostly from farmers. Eventually, in 1925, it was decided that summer time should begin on the day following the third Saturday in April and close after the first Saturday in October.
The U.S. Congress passed the Standard Time Act of 1918 to establish standard time and preserve and set Daylight Saving Time across the continent. This act also devised five time zones throughout the United States: Eastern, Central, Mountain, Pacific, and Alaska. The first time zone was set on "the mean astronomical time of the seventy-fifth degree of longitude west from Greenwich" (England). In 1919, this act was repealed.
President Roosevelt established year-round Daylight Saving Time (also called War Time) from 1942–1945. However, after this period, each state adopted its own DST, which proved to be disconcerting to television and radio broadcasting and transportation. In 1966, President Lyndon Johnson created the Department of Transportation and signed the Uniform Time Act. As a result, the Department of Transportation was given the responsibility for the time laws. During the oil embargo and energy crisis of the 1970s, President Richard Nixon extended DST through the Daylight Saving Time Energy Act of 1973 to conserve energy further. This law was modified in 1986, and Daylight Saving Time was reset to begin on the first Sunday in April (to spring ahead) and end on the last Sunday in October (to fall back).

A. Franklin’s idea of daylight saving
B. Franklin's first conception
C. Franklin’s first official tenure
D. Franklin’s delegation

SHAYNE’S DREAMS COME TRUE - BUT WILL THEY BE SHATTERED?
It is a week before The X Factor live tour when I meet the winner of the series, Shayne Ward. “It has been mental,” he says, referring to the past six months of his life. “I've just been talking to Louis Walsh on the phone. Louis Walsh!” Walsh, a top record producer and The X Factor judge, now manages Shayne’s career. “I was talking to Simon Cowell (a celebrity record producer) yesterday!” He shakes his head in amazement. And these people are telling me they're excited about working with me. “I can't get my head round it.”
Shayne is about as natural as any pop star arriving in the public arena can be. “I just can’t accept where I am now” he says sincerely. “It doesn't feel real. To me, this is just a job.” “What do you think being famous feels like?” I ask him. “I'm not sure, to be honest. Different from this?” he laughs, with only a hint of nerves. Since winning The X Factor, Shayne's success has been phenomenal. His debut single took just three days to reach the number one spot. On tour, he's going to play to audiences of 10,000 on average. He has already brought the house down at a gig in his home city. “I walked out after that performance and just thought, “I’m dreaming!””
Shayne is one of a family of seven children. Times were hard, but he has never wished or a different childhood. Although he thought about going to college, he ended up leaving school at sixteen, just to help his mother pay the rent. He set out on his reality show journey shortly afterwards. When he told he friends he had an audition for The X Factor, none of them really believed him. “I thought I’d go fot it because my family wanted me to, but I never really believed that I would win.”
Naturally, Ward is a fan of reality TV talent shows. “They're brilliant, because people who want recording contracts try for years and get nowhere. Then these competitions come along the people at home decide whether they like the singers or not. So its not just a few people at a record company deciding who gets a chance.” But the previous winner of The X Factor only had one hit. He hasn't been heard of since then. Is Shayne Ward going to be another talent show flop?
A lot of people feel cynical about reality TV show winners and their chances of continuing success. Audiences usually lose interest in them as soon as the show has finished. In fact, contestants on shows like Big Brother are given severe warnings from the show’s producers beforehand, basically telling them “you will not be liked”. Talent shows like The X Factor have to offer contestants a kind of stardom though, and something they can think of as a career, months afterwards at least.

C. the phone call D. the show
Question 40: Which of the following statement is TRUE about Shayne Ward?
A. He is certain how well known he is.
B. He finds his present situation unacceptable.
C. He is confused about the nature of fame.
D. He thinks his job isn’t particularly glamorous.
Question 41: After performing in his home city, Shayne felt
A. overwhelmed B. embarrassed
C. disappointed D. relieved
Question 42: After leaving school at the age of sixteen, Shayne
A. set off on a trip
B. gave up performing
C. got himself a job
D. applied to a college
Question 43: The word “flop” in the passage is closest in meaning to
A. someone who is unpopular
B. someone who is unsuccessful
C. someone who isn’t ambitious
D. someone who lacks character
Question 44: According to the passage, who decide the winner of a reality TV talent show?

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 following questions.
Plants are subject to attack and infection by a remarkable variety of symbiotic species and have evolved a diverse array of mechanisms designed to frustrate the potential colonists. These can be divided into preformed or passive defense mechanisms and inducible or active systems. Passive plant defense comprises physical and chemical barriers that prevent entry of pathogens, such as bacteria, or render tissues unpalatable or toxic to the invader. The external surfaces of plants, in addition to being covered by an epidermis and a waxy cuticle, often carry spiky hairs known as trichomes, which either prevent feeding by insects or may even puncture and kill insect larvae. Other trichomes are sticky and glandular and effectively trap and immobilize insects. If the physical barriers of the plant are breached, then preformed chemicals may inhibit or kill the intruder, and plant tissues contain a diverse array of toxic or potentially toxic substances, such as resins, tannins, glycosides, and alkaloids, many of which are highly effective deterrents to insects that feed on plants. The success of the Colorado beetle in infesting potatoes, for example, seems to be correlated with its high tolerance to alkaloids that normally repel potential pests. Other possible chemical defenses, while not directly toxic to the parasite, may inhibit some essential step in the establishment of a parasitic relationship. For example, glycoproteins in plant cell walls may inactivate enzymes that degrade cell walls. These enzymes are often produced by bacteria and fungi.
Active plant defense mechanisms are comparable to the immune system of vertebrate animals, although the cellular and molecular bases are fundamentally different. Both, however, are triggered in reaction to intrusion, implying that the host has some means of recognizing the presence of a foreign organism. The most dramatic example of an inducible plant defense reaction is the hypersensitive response. In the hypersensitive response, cells undergo rapid necrosis ― that is, they become diseased
and die ― after being penetrated by a parasite ; the parasite itself subsequently ceases to grow and is therefore restricted to one or a few cells around the entry site. Several theories have been put forward to explain the bases of hypersensitive resistance.
Question 1. What does the passage mainly discuss?
A. How the immune system of animals and the defense mechanisms of plants differ
B. How plant defense mechanisms function
C. Theories on active plant defense mechanisms
D. The success of parasites in resisting plant defense mechanisms
Question 2. The phrase "subject to" in line 1 is closest in meaning to
A. attractive to
B. strengthened by
C. classified by
D. susceptible to
Question 3. The word "puncture" in line 8 is closest in meaning to
A. surround B. pinch
C. pierce D. cover
Question 4. The word "which" in line 13 refers to
A. barriers B. tissues
C. substances D. insects
Question 5. Which of the following substances does the author mention as NOT necessarily being toxic to the Colorado beetle?
A. Alkaloids B. Glycosides
C. Resins D. Tannins
Question 6. Why does the author mention "glycoproteins" in line 17?
A. To illustrate how chemicals function in plant defense
B. To emphasize the importance of physical barriers in plant defense
C. To compare plant defense mechanisms to the immune system of animals
D. To introduce the discussion of active defense mechanisms in plants
Question 7. Where in the passage dose the author describe an active plant-defense reaction?
A. Lines 1-3 B. Lines 13-15
C. Lines 19-23 D. Lines 4-6
Question 8. The passage most probable continues with a discussion of theories on
A. the basis of passage plant defense
B. the principles of the hypersensitive response.
C. how chemicals inhibit a parasitic relationship.
D. how plants produce toxic chemical.
