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

As heart disease continues to be the number-one killer in the United States, researchers have become increasingly interested in identifying the potential risk factors that trigger heart attacks. High-fat diets and "life in the fast lane" have long been known to contribute to the high incidence of heart failure. But according to new studies, the list of risk factors may be significantly longer and quite surprising.

Heart failure, for example, appears to have seasonal and temporal patterns. A higher percentage of heart attacks occur in cold weather, and more people experience heart failure on Monday than on any other day of the week. In addition, people are more susceptible to heart attacks in the first few hours after waking. Cardiologists first observed this morning phenomenon in the mid-1980, and have since discovered a number of possible causes. An early-morning rise in blood pressure, heart rate, and concentration of heart stimulating hormones, plus a reduction of blood flow to the heart, may all contribute to the higher incidence of heart attacks between the hours of 8:00 A.M. and 10:00 A.M.

In other studies, both birthdays and bachelorhood have been implicated as risk factors. Statistics reveal that heart attack rates increase significantly for both females and males in the few days immediately preceding and following their birthdays. And unmarried men are more at risk for heart attacks than their married counterparts. Though stress is thought to be linked in some way to all of the aforementioned risk factors, intense research continues in the hope of further comprehending why and how heart failure is

triggered.

Read the following passage and write the letter A, B, C or D on the top of the first page to indicate the correct answer to each of the questions.

The incredible growth of the Internet over recent years has caused problems for parents and teachers. Parents worry about which sites their children spend time on, who they chat to online and the possible effects that computer games might have on them. For teachers, meanwhile, the main worry is the way the Internet makes cheating easier!

Schools and universities say there has been a huge increase in plagiarism – taking other people‟s words and ideas and pretending that they are your own. In the past, anyone who wanted to copy had to go to a library, find the right books, read through them, find the sections they needed and then physically write down the words they wanted to use. Nowadays, though, students can simply copy extracts from websites- while really desperate students sometimes copy whole essays! As if this wasn‟t bad enough, sites offering to actually do homework – at a price – have also started appearing.

Despite all this, we shouldn‟t assume that the Internet only brings problems. Indeed, you could say that for every problem the Internet creates, it also brings a solution. Parents can now use sophisticated controls to stop kids accessing sites that might do them harm, while new software helps teachers to detect copied work immediately. Many, of course, are already able to recognize when someone is cheating! „Some students suddenly start using words they can‟t possibly understand like „dialectical antagonism‟,‟ explains one teacher, „or parts of their essays feel different.”

One of the hardest things for teachers today is deciding how to mix modern technology with traditional study skills – and how best to use the Web in class. As more and more schools install computers in every classroom, the role of the teacher is changing. Making sure students don‟t just copy things and do learn how to quote copied work properly is part of their job, but so is designing suitable projects to fully exploit the Web in helping students students learn about subjects and develop their life and social skills.

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

Until recently, hunting for treasure from shipwrecks was mostly fantasy; with recent technological advances, however, the search for sunken treasure has become more popular as a legitimate endeavor. This has caused a debate between those wanting to salvage the wrecks and those wanting to preserve them.

Treasure hunters are spurred on by the thought of finding caches of gold coins or other valuable objects on a sunken ship. One team of salvagers, for instance, searched the wreck of the RMS Republic, which sank outside the Boston harbor in 1900. The search party, using side-scan sonar, a device that projects sound waves across the ocean bottom and produces a profile of the sea floor, located the wreck in just two and a half days. Before the use of this new technology, such searches could take months or years. The team of divers searched the wreck for two months, finding silver tea services, crystal dinnerware, and thousands of bottles of wine, but they did not find the five and a half tons of American Gold Eagle coins they were searching for.

Preservationists focus on the historic value of a ship. They say that even if a shipwreck's treasure does not have a high monetary value, it can be an invaluable source of historic artifacts that are preserved in nearly mint condition. But once a salvage team has scoured a site, much of the archaeological value is lost. Maritime archaeologists who are preservationists worry that the success of salvagers will attract more treasure-hunting expeditions and thus threaten remaining undiscovered wrecks. Preservationists are lobbying their state lawmakers to legally restrict underwater searches and unregulated salvages. To counter their efforts, treasure hunters argue that without the lure of gold and million-dollar treasures, the wrecks and their historical artifacts would never be recovered at all.
