Writing task 1 sample answers and exercises (Introductory sentence) The line graph compares the spending on five research fields by the US government from 1980 to 2008. Overall, the spending on all kinds of research increased over the period. (Detail paragraph 1) As can be seen from the graph, approximately 8 billion dollars was spent on health studies in 1980 then dipped to around 6 billion dollars before the peak at about 21 billion dollars in 2004. Followed by a slight drop of 1.5 billion dollars in the following 4 years. By contrast, with only 2.5 million dollars from 1980 to 1994, General Science was the least spending in the US throughout the years. Since then, General Science observed a steady growth and double in 2000 to have one more billion dollars till 2008. (Detail paragraph 2) Space, Energy and other fields varied considerably over the given period. Prior to 8 billion dollars in 1997, the amount of funding allocated for Energy studies hovered around 5 billion dollars from 1980 till 1991, and then plummeted to the beginning. Thereafter, this figure grew at 2 million dollars which amounted to 7.5 billion dollars in the 2008. Witness the similar pattern, Space had 9 billion dollars in the last year, 2 million dollars higher than other fields.

being disposed daily in various cities in 2000 Overall, Mexico city was the most polluted city As can be seen from the chart, an equal maximum volume of both SO2 and N2O of approximately 200 microgram per m3 was observed in Mexico City, doubled the minimum amount of around 80 to 100 microgram per m3 Los Angeles was destroyed by N2O, with the minimum and maximum N2O levels 39 and 104 micrograms per m3 respectively, while the maximum volume of SO2 at only 10 microgram per m3 The second most pollute city was Beijing where a minimum of 25 microgram per m3 and a maximum of 130 micrograms per m3 of SO2 on a daily basis, whereas the level of N2O ranged from 14 to 54 units Air quality in Calcuta was polluted by approximately 47 to 59 microgram per m3 of SO2 and 30 to 52 micrograms per m3 of SO2 19 There are many people believe that social networking sites (such as Facebook ) have a huge negative affect on both individuals and society From my perspective, I completely agree with this and I will elaborate on the reasons in following paragraphs On the one hand, although social networking sites are developing strongly, they still have big negative impact on both individuals and society because people will lag behind in developing world One standout example of this is using Facebook The software programmers who like to watch useless things, such as comedy clips, friends’ photo or advertisement videos on Facebook will lack of their knowledge If these programmers not spend time learning new programming languages or new technical methods, day by day these programmers can not apply new technical applications, they can not make good products for their company These programmers can not improve their career and they also make bad effect on their company On the other hand, social networking sites still have some positive affect on both individuals and society This is because those social networking sites are providing huge community of users where companies can introduce their products to users quickly and spend less money for advertisement than other social media It helps them get more profit on business If companies good business, they not only help to improve their company but they also help economic development for countries In conclusion, although I concede that there are many advantages of using social networking sites but I still agree that social networking sites have huge negative impact on individuals and society because by spending much time for using them, people will lag by their own achievements Question 7: Air pollution in four

to practise writing your overviews: Find a chart and write an overview, then send it to a friend or classmate Ask them to draw the chart from your overview If it looks totally different, write your overview again Repeat until your friend can draw a graph that looks similar Repeat this regularly until you can write a good overview every time.” 22
