DOKUMEN NEGAR




The text is for question 16 and 17





To the manager of Taco Tacontento
            I am writing to bring to your attention a serious issue I had in your establishment last week. I ordered a vegetarian bean burrito, and halfway through my meal, I bit into what turned out to be a chicken bone.
            I am a vegetarian, and the presence of bone in my burrito was jarring. I showed the bone to the staff, who offered to make me a new burrito with the same beans the bone presumably came from. I did not want to risk eating any meat of finding another bone, so I asked for a taco salad instead.
            I am a regular customer at your restaurant, and I have never had any problems with your food in the past. While I am relatively certain this was a fluke, I am still concerned about how the bone got into the beans. I would like to know how this might have happened.
            I am also concerned with the ack of understanding I received from the staff member who helped me. I don’t know if she was working alone of merely misunderstood my request, but she refused to let me speak to her supervisor while I was in the restaurant. I felt she acted very unprofessionally.
            I hope to hear back from you about this incident. I can be reached by phone at (555)867-5309 at any time or by email at mhoss@mailclient.com.

Sincerely,
Marilyn Hoss

The following text is for question 30  to 32
            Nowadays, many people have realized that agriculture is much more important than other supporting tools in economic development. In Indonesia, agriculture should be the priority of development because of some good reasons.
            First of all, the agriculture’s contribution in the beginning of the development of the country was the highest of all sectors. At present, almost half of the total Indonesian labors are working in aagriculture sectors, but the contribution of agriculture sector does not reach 30 percent.
            Second, agriculture sector is expected to fulfill the need of food in the country. As the number of population increases in an alarming rate each year, food supply must also increase but agricultural production percapita never increases more than one precent each year, and in some extreme cases, it is even stangnant.
            Last but not least, without agricultural development, the growth of industrial sector will be hampered because the growth that coes from industry will bring a wider gap into the internal economy in that country. In turn, this gap will  create serious poverty problem, wider inequality of income distribution, and increase unemployment.
            Based on the above discussion, it is obvious that the government should put agriculture as the priority of national development.

This text is questions 33 to 35
            It is just one of three movies opening this week featuring rising star George MacKay, a gifted and versatile actor whose ship appear to have come. In this affecting and atmospheric fable he plays Aaron, the sole survivor of mysterious fishing accident in which several souls were lost, including his long-idolised older brother.
            Stigmatized by the insular Scottish community who blame him for the enexplained tragedy and anraptured by fairytale memories of a ses devil that swallowed children into its “dirty belly” , this wandering ghost is drawn back to the dark waters whose whispered secreats haunt his waking dreams. With its shifting visual and avocativesoundscpes, this is an arresting and hypnotic feature debut from writer-director Paul Wright, who won a Bafta with his short film Until the River Runs Red.
            The extraordianary Kate Dickie is utterly believable as the heartbroken mother whose beside stories fired her son’s imagination, and whose karaoke rendition of the First Time Ever I Saw Your Face rings with almost unbeareable pathos. Michael Smiley is equally strong as the putative father-in-law with an overprotective mean streak who becomes Aaron’s physical adversary, but the real monsterhere are altogether more mythical and elusive. A full aweek after first viewing, I find myself still sifting through montage images that linger in the mind like a half-remembered dream.

ALL THROUGH THE NIGHT
Marry Higgins Clark
            Reading Marry Higgins Clark always remind me of watching “Murder She Wrote”.The show usually had three plot lines – the standard “rule of three” – and by the end of the hour it was wrapped neatly like a nice package with Angela Lansbury tying up the loose ends by solving the case brilliantly. Throught we knew the formula, it never kept us from tuning in, usually for the sheer pleasure of escape and watching the story unfold.
            The three plot in All Throught the Night concern a stolen chalice, a missing baby and a will which seems to be fraudulent. To solve the mystery, she revives her beloved characters Alvirah and Willy Meehan – the former cleaning woman and plumber who won the lottery and left their life in Jackson Heights, Queens for an apartment on central park. Like Angela Lansbury, the two  of them have fun along the way solving the way solving the puzzle.
            The pace is swift and the story is a pure escape – totally fun Mary Higgins Clark. I admit however, that I am still trying to conjure up what the melody of the song “All Throught the Night” sounds like
            This holiday season, put the aside your chores and curl up on the couch with “All Throught the Night”. When you close it you will be relaxed and more ready to enjoy the festivities. and then you might just want to tuck a copy into someone’s stocking or gift bag, as well.
36. Who is the writer of the book “All Throght The Night” ?

The text is for question 39.





            Part of the decision to live the homeschooling lifestyle should include weighing the pros and cons of homeschooling. Those who favor homeschooling state that it is educational freedom.Most homeschooled students have the choice to study and learn what they want,when they want,for as long they want.With your lives no longer revolving around school hours,homework and the school calendar,your family can plan off-season vacations, visit parks and museums during the week,andlive your lives according to what works for you.Next,it is certainly emotional freedom.Sadly,peer pressure,competition,boredom,and bullies-are all part of a typical school day .Homeschooled kids can dress,act and think the way they want,without fear of ridicule or a need to “fit in”.But,the opponents are of different views.Homeschooling is time restraints. Homeschooling can be a full-time job unto itself.It takes research,preparation,time to set up,clean-up,organization,and of course,teaching itself.This is lot to do on top of other work,be that a job outside the home,or all that goes with running a family.It also has financial restraints .For married parents,one partner often foregoes full-time employment out of the home in order to homeschool.This can be a big sacrifice for families who are struggling to balance their budget.
 
 










39.  Parents prefer homeschooling to conventional education as …
A. homeschooling frees children from physical,mental and emotional pressures
B. conventional schooling takes up sizeable time and money of parents
C. Formal education tends to put more emphasis on academic learning
D. homeschooled children’s talent can be more optimally developed
E. children educated formally tend to develop violence



The following textis for questions 40-41.





The Music Downloading Controversy
As the title implies there is an ongoing debate about music downloading. The Recording Industry Association of America (RIAA) along with several recording artist filed lawsuits against the company alleging that they “infringed” on record labels’copyrighted music is illegal, but many industry professionals avid downloaders and legal experts are still debating whether or not it can be viewed as immoral.
      There are those who believe that downloading a song without paying for it is not only illegal,but immoral. Nonetheless,people continue to download songs anyway,rationalizing that the record companies are getting what they deserve years after overpriced CD’s or that the artists won’t really miss the money.Some people are not sure what to make of the situation,sympathizing in some respects with either side.There are several proposed solutions to this problem,but it has become obvious that there is not easy or clear answer.
     After recording companies experienced record losses over the last few years contributed largely to this controversial practice,the RIAA has made its positions clear.They commenced to “take legal action against thousands of people for illegally sharing music files”.They view this as the first step to encouraging file-sharers to stop illegally downloading music.RIAA is not the only parties potentially harmed  by illegal file-sharing,but also the artists who work to produce these albums Recording artists Anastasia feels that “if you dig an artist that much,then you should want to help keep that artists alive,by purchasing one file-sharing is a considered a large threat to the entertainment industry.
      Many down-loaders realize that this activity is illegal,but they are unclear about how it can be construed as unethical.Many of the individuals who engage in file sharing are teenagers undoubtedly with limited budgets.For them ,the harmfull effects of their download on multimillionaire recording artists are negligible.Futhermore,it is difficult for them to viem the situation from the standpoint of pampered artists and greedy recording companies.In the day before music down-loads,CDs cost about $17.99.Listener often argued that they had overpaid because albums have only one or two good songs.Moreover, artists usually only received a fraction of the proceeds,making recording companies wealthy.Others believe that downloading music is okay as long as the person does not burn CDs and sell them.
 
 























40.  According to those who agree,music downloading is ….
        A.  harmful for both recording companies and the antists
        B.  not harmful since the recording companies are greedy
        C.  okay as the person does not have budget to get the CDS
        D.  okay unless for business purposes
        E.  okay because only teenagers who download music
41.  “…recording artist are negligible” (Paragraph 4).
The underlined word is closest in meaning to ….
A.     Very urgent
B.     Unpredictable
C.     Insignificant
D.     Not effective

            Climate change is the consequence of unchecked olution. When carbon emissions caused by human activity enter the air they have dangerous effects on the environment, the economy, and our wellbeing. But Justas humans cause it, we can stop its progress. Climate change is caused by trapping exces carbon in Earth’s atmosphere, This trapped carbon pollution heats up, altering the Eart’s climate patterns. The largest source of this pollution is the burning of fossil fuels such as coal and oil for energy. While carbon has entered the atmosphere for millions of year through natural events such as forest fires and volcanoes, the burning of fossil fuels and the clearing of land have resulted in the highest levels of greenhouse pollution in our atmosphere in the last 800,00 years. The Earth’s atmosphere has evolved to retain sufficient warmth from the sun to encourage a healthy, dynamic ecosystem, while shielding us from its harsher effects. The introduction of huge amounts of excess pollutants thickens this blanket of protective gases, causing heat to remain trapped within, rather than harmlessly escaping skywards. These gases can remain in our atmosphere for up to 90 years, contributing to long-term warming.
 
 















42. What is the topic of the text?
A.    Processes in the event of the greenhouse pollution.
B.     Relationship between pollution and climate.
C.     Effect of air pollution on the atmosphere
D.    Meanings of global warming.
E.     Causes of climate change.
